how to transfer oversized string over message system

for text based message system, if there's a limit of x KB, you can still transfer (~5 * x) KB by

1. compressing the original payload
2. encoding compressed binary to text
3. sending it

receiver reverses the process to get original payload by

1. testing to make sure message is encoded
2. decoding it to compressed binary
3. uncompressing decoded binary

import org.apache.commons.codec.binary.Base64;

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;

String payload = """
        {
        }""";
System.out.printf("original size: %s bytes\n", payload.length());

ByteArrayOutputStream baos = new ByteArrayOutputStream();
GZIPOutputStream gos = new GZIPOutputStream(baos);
gos.write(payload.getBytes());
gos.close();
byte[] compressed = baos.toByteArray();
System.out.printf("compressed size: %s bytes\n", compressed.length);

String encoded = Base64.encodeBase64String(compressed);
System.out.printf("encoded size: %s bytes\n", encoded.length());

System.out.println("is message encoded? " + Base64.isBase64(encoded));
byte[] decoded = Base64.decodeBase64(encoded.getBytes());
System.out.printf("decoded size: %s bytes\n", decoded.length);

GZIPInputStream gis = new GZIPInputStream(new ByteArrayInputStream(decoded));
ByteArrayOutputStream output = new ByteArrayOutputStream();
byte[] buffer = new byte[4096];
int bytesRead;
while ((bytesRead = gis.read(buffer)) > 0) {
    output.write(buffer, 0, bytesRead);
}

gis.close();
String uncompressed = output.toString();
System.out.printf("uncompressed size: %s bytes\n", uncompressed.length());

original size: 9450 bytes

compressed size: 1235 bytes

encoded size: 1648 bytes

is message encoded? true

decoded size: 1235 bytes

uncompressed size: 9450 bytes

mixing spring boot web and webflux

Following how to use reactor scheduler in micro-services, things becomes even more tricky if you mix spring boot web and webflux.

how to use reactor scheduler in micro-services

Depending on how many cores we have for your micro-services, we may have as low as 4 threads (reactor-http-nio- or reactor-http-epoll-) when it comes to listening and talking to outside. If these threads are blocked in a way we didn't expect, the performance could be worse than traditional synchronised paradigm. Here're a few examples to show how it works when offloading blocking operations to a larger thread pool at different places. Logs happen at doOnSubscribe and doOnSuccess.

Customise IntelliJ IDEA

I'm happy with default behaviour of this IDE overall. Here're the only couple of settings I'd like to change.

Enable Full Text Search for MongoDB

If you get this in mongo console
db.coll.ensureIndex({'content':'text'})
{
    "err" : "text search not enabled",
    "code" : 16633,
    "n" : 0,
    "connectionId" : 1,
    "ok" : 1
}

, and this in mongod console
[conn1] insert test.system.indexes keyUpdates:0 exception: text search not enabled code:16633 locks(micros) w:336411 336ms

, you need to enable full text search when starting MongoDB.
mongod --setParameter textSearchEnabled=true

Try again.
db.coll.ensureIndex({'content':'text'})

Check indexes.
db.coll.getIndexes()
[
    {
        "v" : 1,
        "key" : {
            "_id" : 1
        },
        "ns" : "test.coll",
        "name" : "_id_"
    },
    {
        "v" : 1,
        "key" : {
            "_fts" : "text",
            "_ftsx" : 1
        },
        "ns" : "test.coll",
        "name" : "content_text",
        "weights" : {
            "content" : 1
        },
        "default_language" : "english",
        "language_override" : "language",
        "textIndexVersion" : 1
    }
]

Check index size. It's about half the text size it indexed.
db.coll.stats()
{
    "ns" : "test.coll",
    "count" : 6245,
    "size" : 69054068,
    "avgObjSize" : 11057.496877502002,

        "_id_" : 212576,
        "content_text" : 85381968
    },
    "ok" : 1
}

Have a test.
db.coll.runCommand("text", {search:'Hello'})
{
    "queryDebugString" : "hello||||||",
    "language" : "english",
    "results" : []
    "stats" : {
        "nscanned" : 4,
        "nscannedObjects" : 0,
        "n" : 4,
        "nfound" : 4,
        "timeMicros" : 157
    },
    "ok" : 1
}

Not bad.

Java development using Ubuntu 11.10 and OpenJDK 7

I tried Ubuntu 11.10 Oneiric Ocelot Beta 1. LightDM is lighter and beautiful. Maybe I can keep using Ubuntu on my ThinkPad T42, rather than jumping onto Lubuntu.

Due to the retiring of the "Operating System Distributor License for Java (DLJ)", Sun / Oracle JDKs / JREs cannot be installed by enabling Canonical Partners' repository any more. It's a good news to OpenJDK. With more usage of OpenJDK, we can expect higher priority and fewer bugs.

Since Java 7 is out, the first thing I did is installing OpenJDK 7. From Ubuntu Software Centre, you can only install JRE. I miss Synaptic Package Manager.
sudo apt-get install openjdk-7-jdk

Change default JRE of system from OpenJDK 6 to 7.
sudo update-alternatives --config java

I got following error when installing Subclipse plugin to Eclipse.
An internal error occurred during: "Install download0".
Library /usr/lib/i386-linux-gnu/libsoftokn3.so does not exist

Creating a symbolic link sovled it.
cd /usr/lib/i386-linux-gnu/
sudo ln -s nss/libsoftokn3.so libsoftokn3.so

After Subclipse is installed, I had a small problem in starting Eclipse 3.7 Indigo, but it's a common one.

sudo apt-get install libsvn-java
and
-Djava.library.path=/usr/lib/jni
in eclipse.ini solved it.

m2eclipse and Google plugin for Eclipse work out of box. Maven 3.0.3 works fine with OpenJDK 7.

Apache Tomcat 7.0.21 works fine with OpenJDK 1.7.0 but if you haven't created the above symbolic link, you'll get below error when starting Tomcat.
java.security.ProviderException: Library /usr/lib/i386-linux-gnu/libsoftokn3.so does not exist

I also tried to install Gnome Shell.
sudo apt-get purge gnome-shell

Installation finished successfully but later when I specified Gnome to login, I got a dialog box saying
failed to load session "gnome"

There are a couple of solutions to the problem but none works for me, so I installed classic Gnome.
sudo apt-get install gnome-session-fallback

A fantastic experience, I'm looking forward to its release next month.

Return code 400 when creating a new feature type

I came across a 400 return code when I tried to use REST Configuration API of GeoServer to create a new feature type. The reference doesn't give any explanation to it. From GeoServer's log, I got

ERROR [geoserver.rest] - No such feature type:

It shows that I'm trying to publish a feature type that doesn't exist. Problem solved here but I'd like to go the extra mile, check the source of FeatureTypeResource#buildFeatureType.

170  if(fti.getName() == null) {
171     throw new RestletException("Trying to create new feature type inside the store, " +
172              "but no feature type name was specified", Status.CLIENT_ERROR_BAD_REQUEST);
173  } else if(fti.getAttributes() == null || fti.getAttributes() == null) {
174      throw new RestletException("Trying to create new feature type inside the store, " +
175              "but no attributes were specified", Status.CLIENT_ERROR_BAD_REQUEST);
176  }

WTF is line 173 doing?

How to add another data source in JPA

It's quite easy to create a data source using JPA support of Spring framework. It not so difficult to add another data source to your application as well.

In META-INF/persistence.xml, define another persistence unit.

     <persistence-unit name="anotherUnit" transaction-type="RESOURCE_LOCAL">  
         <class>com.youcompany.YourClass</class>  
         <exclude-unlisted-classes>true</exclude-unlisted-classes>  
         <properties>  
             <property name="hibernate.hbm2ddl.auto" value="update" />  
             <!-- validate | update | create | create-drop -->  
         </properties>  
     </persistence-unit>  

Note that you should define all the domain classes you will be using in the defined persistence unit in <class> elements.

Define another database context xml file.

 <?xml version="1.0" encoding="UTF-8"?>

     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

         <property name="minEvictableIdleTimeMillis" value="${dbcp.minEvictableIdleTimeMillis}" />  
     </bean>  
     <bean id="anotherJpaAdapter"  
         class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"

     <bean id="anotherEntityManagerFactory"  
         class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"  
         p:dataSource-ref="anotherDataSource" p:jpaVendorAdapter-ref="anotherJpaAdapter">  
         <property name="loadTimeWeaver">  
             <bean  
                 class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver" />  
         </property>  
         <property name="persistenceUnitName" value="anotherUnit"></property>  
     </bean>  
     <bean id="anotherTxManager" class="org.springframework.orm.jpa.JpaTransactionManager"  
         p:entityManagerFactory-ref="anotherEntityManagerFactory" />  
 </beans>  

In the JPA implementation of generic DAO class, annotate the 1st persistence unit in the setter of EntityManager.

     protected EntityManager entityManager;  
     @PersistenceContext(unitName="firstUnit")  
     public void setEntityManager(EntityManager entityManager) {  
         this.entityManager = entityManager;  
     }  

Create another generic DAO class for new persistence unit. All the operations to the new domain objects should be accomplished via this new generic DAO.

If you want to access data source directly, use

     @Autowired  
     @Qualifier("anotherDataSource")  
     private DataSource dataSource;  

Don't forget to getAutoCommit and keep the status of any connection you get from data source if you need to setAutoCommit yourself, and close the connection in finally statement.

That's it.

These user agents have accessed myTunes

myTunes is my personal project aggregating popular Chinese podcasts finished in 2006. Its core functions are generating dynamic RSS feeds (such as all the video contents, all the mp3 contents, etc), and providing OPML, which iTunes supports from several years ago. The UI, which is just a consumer of myTunes' API (RSS and OPML), is implemented in JSF.

I promised to publish all the user agents that have accessed myTunes and I think it's the right time now.


Thanks Datong for this pretty logo.

Good practice in using java.util.concurrent

Concurrent package was introduced from Java 5 and still doesn't get reasonable acceptance. Traditional thread programming is just too strong for us to unlearn it. Several years ago, I created a task framework to solve commonly used scenario, a modified version (most changes are generic related) is used in a product I participated in 2008.

In my current project, I have a requirement of setting timeout for serials of web service operations, which is very suitable for concurrent package. I learned a good lesson from this simple task. I reckon I need to revise my framework one day.

The 1st lesson I learned is it's harder and not safe to set thread name to a Callable thread. One workaround is calling Thread.currentThread().setName() at the beginning of call(). But thread is not owned by Callable but by ExecutorService, so this might have some side-effects. Use it at your own risk.

The 2nd one is the overhead of creating and removing threads is much heavier than I imaged before. In debug mode you can see the process of creation and removal of threads, especially when you submit the thread in loops. Try your best to minimize the operations in call() and only call call() when necessary.

Third tip is by using Future.get(1L, TimeUnit.MILLISECONDS) and ignoring TimeoutException you get an asynchronized thread.

Last but not least is always cancel future and shutdown service. If you fail to do so, the callable will be in running status forever and eventually you'll have no memory to create any new thread. Although I don't see any difference between Future.cancel(true) and Future.cancel(false), ExecutorService.shutdown() and ExecutorService.shutdownNow() in my case.

One more bug submitted

createRecordComponent is not called for the first record created

I'm using Smart GWT 2.2 and facing a strange bug. The com.smartgwt.client.widgets.grid.ListGrid#createRecordComponent(ListGridRecord record, Integer colNum) is not called for the very first record. Thanks to smartgwt's popularity, I found some complaints and workarounds.

In Issue 450 - smartgwt - createRecordComponent(final ListGridRecord record, Integer colNum) {} never executed, someone suggested create a function that does all the job createRecordComponent is supposed to do and call this function explicitly. If this works, the event model needs also to be hacked, because nothing wrong in createRecordComponent. Hope he/she will contribute the solution to the product.

In createRecordComponent not called for changed record when refreshing ListGrid, another one suggested showRecordComponent must be implemented as well, if not all the columns' component are created in create/updateRecordComponent. Sounds simple but no matter showRecordComponent returns true or false, createRecordComponent still fails to be called.

What helped me is ListGrid.createRecordComponent not called unless a column is sorted. I don't call setSortField because I have no field to sort. I call ListGrid#sort after a new record is added and problem solved.

soapUI 3.5.1 on Ubuntu 10.04

Update: soapUI 3.6.1 on Ubuntu 10.10 doesn't have the following problem.

I got following error in my console when I tried to run soapUI on Ubuntu. It was started, after a blank splash screen, but cannot create a project.

Exception in thread "XpcMessageLoop" java.lang.NoSuchMethodError: com.jniwrapper.gtk.GTK.initialize([Ljava/lang/String;)V
    at com.teamdev.xpcom.impl.awt.linux.AwtLinuxPlatform.a(SourceFile:166)
    at com.teamdev.xpcom.impl.E.initialize(SourceFile:69)
    at com.teamdev.xpcom.c.run(SourceFile:150)

The solution is to uncomment the following line in soapui.sh

# JAVA_OPTS="$JAVA_OPTS -Dsoapui.jxbrowser.disable=true"

To set authentication information for a web service, use this dialog box.

How to connect an InputStream to an OutputStream

In the FTP Proxy product, one basic requirement is to intercept upstream authentication commands (USER and PASS commands sent from FTP client to FTP server), finish customized authentication and then let FTP client and FTP server work together with following tasks.

For upstream commands, the proxy has an inputstream from client and an output stream to server; for downstream commands, it has an inputstream from server and an inputstream to client. An easy way to deal with it is StreamConnector.

Don't mix up with similar solutions like Convert a Java OutputStream to an InputStream and Java utilities for stream wiring and file format detection.

Where is Sun Java?

Trust yourself should be 1st law in open source world.

I installed Ubuntu 10.04 and noticed Sun Java in not in default repository any more. I checked Ubuntu 10.04 LTS Release Notes and found

Sun Java moved to the Partner repository

For Ubuntu 10.04 LTS, the sun-java6 packages have been dropped from the Multiverse section of the Ubuntu archive. It is recommended that you use openjdk-6 instead.

If you can not switch from the proprietary Sun JDK/JRE to OpenJDK, you can install sun-java6 packages from the Canonical Partner Repository. You can configure your system to use this repository via command-line:

add-apt-repository "deb http://archive.canonical.com/ lucid partner"

Easy, but it's wrong. Here is how to enable partner's repository.

 

You can see the leftover of the wrong command. What a(nother) shame.

Submitted another bug to Eclipse

It's unavoidable to have ambiguous types in single Java file. The way to solve the problem is very easy, using fully qualified class name. Unfortunately, the Content Assist of Eclipse 3.6M4 is not that smart to generate correct code.

I submitted this bug to Eclipse today and let's see what will happen.

Schema of iTunes podcast feed

In 2006, in order to aggregate my favourite podcasts and share them with other iPod owners, I did a podcast aggregation service named myTunes.

I chose JAXB to map XML documents to Java objects and vice versa, so I need a schema or DTD file of iTunes podcast feed. Unfortunately I couldn't find one. I had to generate one myself.

I got an example feed from Apple. I removed a few elements that I think of no use at the moment and generated its schema.

Then I created Java classes (ObjectFactory.java, Rss.java, ChannelType.java, ImageType.java, ItemType.java and EnclosureType.java) using xjc. Now we're ready to output iTunes compatible podcast feed.

I had closed myTunes before I moved to Melbourne in 2008. In less than 2 years, myTunes collected several hundreds of user agent (it only collects user agent, nothing else). I think it'll be a good idea to publish them one day.
