JMS for Osgi-Bundle Communication

Hey,
I want to use jms for commuication between OSGi-Bundles. I have implementet the bundles so far, but I get the following error message:

Has anybody an idea, how I can fix this
Chris

Hello there,
Many thanks for the reply,
Well just clarify i may be wrong, i said i need 100 queues is because
we have hunderds of brokers office where we can place orders
our requirement is as below.
a) One client can place multiple orders with MULTIPLE brokers simultaneously. i.e choose different brokers and do a long and short
at the same time
b) Now based on the brokers chosen by the client orders must be
routed to multiple broker's office
c) same way trade updates / trade confirmation's need to be sent
to the client , please note that MULTIPLE brokers will be sending
the orders to the SINGLE client
d) Now i need a reliable channel to do this, both of the actions (point
b and c ) is async . Unless i create a seperate queue for each of
the brokers how is it possible to reliably (i mean specific broker / client) to communicate with each other
e) It is a complex scenario , please do let me know if you can get the point , if not please do mention i will try to simplify my questions
Would greatly appreciate if someone can help to scrutinize on the architecture , more importantly if JMS is appropriate here.
Many thanks,

What is the best practise to provide a text file for a Java class in a OSGi bundle in CQ?

This is probably a very basic question so please bear with me.
What is the best way to provide a .txt file to be read by a Java class in a OSGi bundle in CQ 5.5?
I have been able to read a file called "test.txt" that I put in a structure like this /src/resources/<any-sub-folder>/test.txt from my java class at /src/main/java/com/test/mytest/Test.java using the bundle's getResource and getEntry calls but I was not able to use the context.getDataFile. How is this getDataFile method call to be used?
And what if I want to read the file located in another bundle, is it possible? or can I add the file to some repository and then access it - but I am not clear how to do this.
And I would also like to know what is the best practise if I need to provide a large data set in a flat file to be read by a Java class in CQ5.
Please provide detailed steps or point me to a how to guide or other helpful resources as I am a novice.
Thank you in advance for your time and help.
VS

As you can read in the OSGi Core specification (section 4.5.2), the getDataFile() method is to read/write a file in the bundle's private persistent area. It cannot be used to read files contained in the bundle. The issue Sham mentions refers to a version of Felix which is not used in CQ.
The methods you mentioned (getResource and getEntry) are appropriate for reading files contained in a bundle.
Reading a file from the repository is done using the JCR API. You can see a blueprint for how to do this by looking at the readFile method in http://svn.apache.org/repos/asf/jackrabbit/tags/2.4.0/jackrabbit-jcr-commons/src/main/java /org/apache/jackrabbit/commons/JcrUtils.java. Unfortunately, this method is not currently usable as it was declared incorrectly (should be a static method, but is an instance method).

Create OSGi Bundle for GSA JAPI

Hi
We will be using GSA for the search feature for the website built in CQ5.4. For integration we are using GSA JAPI (http://gsa-japi.sourceforge.net/gsa-japi.html), however I am getting error with the JAR that was converted to the OSGi Bundle based on the instructions given in the knowledge base "How to Convert a jar File into an OSGi Bundle" (http://dev.day.com/content/kb/home/cq5/Development/ApacheFelix/ConvertAJarIntoOsgiBundle.h tml).
Error is in the import statement itself. Currently I have taken the source code and created the OSGi bundle, but then this is tedious to maintain. Can you please suggest on how to convert the jar to the osgi bundle or any other alternative solution.
Thanks,
Chetanya

Hi Chetanya,
It sounds like you already have everything you need. Regarding future maintenance of GSA JAPI, it looks like there hasn't been a new release in four years, so you might be safe there. Also, you could consider submitting the manifest file you created back to the project - perhaps the maintainers would consider making an update?
Thanks,
Matt

When using rabbitmq-jms for vFabric RabbitMQ javax.jms.Message.getJMSDestination does not return the actual destination when it is received from a consumer listening on a Topic with a wild card

When using rabbitmq-jms for vFabric RabbitMQ javax.jms.Message.getJMSDestination does not return the actual destination when it is received from a consumer listening on a Topic with a wild card. I have tested with both 1.0.3 and 1.0.5 clients with RabbitMQ 3.1.5.
I was wondering if the community was aware of this problem and if there are any workarounds? If not what is the proper channel to file a bug report. An example code snippet is below. The test fails because the TextMessageMatcher expects the destination passed in on construction (second parameter) to equal the desination on the message received (aquired from getJMSDestination).
        Mockery context = new Mockery();
        final MessageListener messageListener = context.mock(MessageListener.class);
        final Latch latch = new LatchImpl();
        final String prefix = "test" + System.currentTimeMillis();
        context.checking(new Expectations() {
                oneOf(messageListener).onMessage(with(new TextMessageMatcher("MSG1", prefix + ".1234")));
                will(new CustomAction("release latch") {
                    @Override
                    public Object invoke(Invocation invocation) throws Throwable {
                        latch.unlatch();
                        return null;
        final Connection connection = createConnection(null, null);
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        connection.start();
        Topic wildcardTopic = (Topic) getInitialContext().lookup(prefix + "." + "#");
        Topic destination = (Topic) getInitialContext().lookup(prefix + ".1234");
        final MessageConsumer consumer = session.createConsumer(wildcardTopic);
        consumer.setMessageListener(messageListener);
        MessageProducer producer = session.createProducer(null);
        producer.send(destination, session.createTextMessage("MSG1"));
        latch.await(5000);
        connection.close();
        Thread.sleep(5);
        context.assertIsSatisfied();

Cannot load css files into osgi bundle

I want to create JavaFX application based on several osgi bundles. I use Felix framework for osgi container. I face the same issue as this post
Exception logged when using custom css in JavaFX in Felix OSGI
How I can set globally
-Dbinary.css=false
Into the start JavaFX method. I would like at a low level to configure this.

This should not be any issue with PE7 as it is meant for opening any supported not corrupted image. Can you please re check this issue with you. Make sure you have copied the image successfully and completely from your phone to your machine.
If again you are facing the issue please share the image your are trying to open.

Replication from an OSGI bundle - help

I am an OSGI newb!
I create a custom WorkflowProcess that is called from a WorkflowLauncher when a certain node gets created on the Author instance. The WorkflowProcess needs to replicate the node structure onder this node to the publisher.
I am having problems using the Replicator from the WorkflowProcess in the OSGI bundle. I am not about to instantiate an instance of com.day.cq.replication.Replicator. I have tried using the @Reference annotation, but at runtime the replicator is null. I have seen suggestions of using the Sling on the front end but that is not what I am looking for.
So my questions are:
1.) How do I get an instance of com.day.cq.replication.Replicator from inside a WorkflowProcess (WorkflowSession)?
2.) Can I use Sling in the bundle?
3.) Is there an easier way to do this?
4.) Can I programmatically connect to the Publish server from my WorkflowSession and create the nodes with jcr?
Thanks.

The code to manually trigger replicator would look somewhat like this:
import javax.jcr.Session;
import com.day.cq.replication.Replicator;
import org.apache.sling.jcr.api.SlingRepository;
@Reference
private Replicator replicator;
@Reference
private SlingRepository repository;
try{
     Session session = repository.loginAdministrative(null);
     replicator.replicate(session, ReplicationActionType.ACTIVATE, path);
finally{
     if (session != null){
          session.logout();
          session = null;

OSGi bundle JNI load/unload problem

Hi everybody!!
One more thread about the topic. I still didn't find a solution. Can anybody help me?
I have an OSGi bundle that access native methods from a JNI library (for a medical device). I could make my bundle work once, but the second time I tried to access the methods, the dll was still in use I couldn't get data from the methods.
This is the class I used (I even tried with a custom libloader):
public class Omron637ITjni {
     /*Native functions from the JNI dll*/
     public native int OmronInit();
     public native int OmronClose();
     public native int OmronFinish();
     public native int OmronOpen(int disp);
     public native int OmronRead(MeasurementData MData, int pos);
     public native void OmronNumRead(DataCount DCount);
     static{
          //Using LibLoader
          /*try {
          LibLoader.loadCommLib("omron637IT");
          catch ( Exception x ) {
          // do what is necessary
               System.out.println(x);
          //Using System Commander
          try{
               System.out.println("Charging Library Omron");
               System.loadLibrary("omron637IT");
          }catch(UnsatisfiedLinkError unsatisfiedlinkerror)
System.out.println("Error loading library: " + unsatisfiedlinkerror);
As it seems not to work, I'm trying with Singleton pattern. This is my new class:
public class Omron637ITjni_Singleton {
          * Native functions from the JNI dll
          public native int OmronInit();
          public native int OmronClose();
          public native int OmronFinish();
          public native int OmronOpen(int disp);
          public native int OmronRead(MeasurementData MData, int pos);
          public native void OmronNumRead(DataCount DCount);
          private static Omron637ITjni_Singleton singleton;
          * Instance accessor following singleton.
          public static Omron637ITjni_Singleton getInstance() {
               if (singleton == null){
                    System.out.println("Create Object");
                    singleton = new Omron637ITjni_Singleton();
               else{
                    System.out.println("Object already created; use instance");
               return singleton;
          * Private constructor to ensure that a <tt>ResourceManager</tt>
          * cannot be constructed from outside this class.
          private Omron637ITjni_Singleton() {
          static{
               //Using LibLoader
               /*try {
               LibLoader.loadCommLib("omron637IT");
               catch ( Exception x ) {
               // do what is necessary
                    System.out.println(x);
               try {
                    System.out.println("Charging Omron library from Singleton");
                    System.loadLibrary("omron637IT");
                    System.out.println("Library charged");
               } catch (UnsatisfiedLinkError ule) {
                    System.out.println("Error loading library: " + ule);
At this very moment, when executing
Omron637ITjni_Singleton jni = Omron637ITjni_Singleton.getInstance();
from the Activator, I get from the Knopflerfish console:
[stdout] omron637ITBPM starting...
[stdout] Service registered: Omron 637IT Blood Pressure Monitor
[stdout] Charging Library Omron desde Singleton
[stdout] Library chatged
[stdout] Create object
Then, I call a services provided by the bundle:
framework call omron637IT.Omron637ITInterface getData
which calls the following function:
public void getData() {
          // TODO Auto-generated method stub
          //Omron637ITjni jni = new Omron637ITjni();
          //Singleton
          Omron637ITjni_Singleton jni = Omron637ITjni_Singleton.getInstance();
          try {
               int res = jni.OmronInit();
               int ok_open = jni.OmronOpen(res);
               System.out.println("The attempt of connecting the Omron637IT device ended with code: " + ok_open + " [(0) normal (1) still in process (2) error]");
               if (ok_open == 0){ //OK
                    DataCount NumData = new DataCount();
                    jni.OmronNumRead(NumData);
                    System.out.println("DATA");
                    System.out.println("----");
                    for (int pos = 0;pos<NumData.nData1;pos++){
                         MeasurementData Data = new MeasurementData();
                         int ok_read = jni.OmronRead(Data,pos);
                         int annyo = Data.cYear + 2000;
                         int i = pos + 1;
                         if (ok_read == 0)
                              System.out.println("Num: " + i + "; Date-> " + Data.cDay + "/" + Data.cMonth + "/" + annyo + "; Time-> " + Data.cTime + ":" + Data.cMinute + ":" + Data.cSecond + "; Sys-> " + Data.nSys + "; Dia-> " + Data.cDia + "; Pls-> " + Data.cPls);
                    int stop = jni.OmronClose();
                    System.out.println("Close with code " + stop + " Right?");
                    int finish = jni.OmronFinish();
                    System.out.println("Finish with code " + finish + " Right?");
                    System.gc();
                    System.gc();
               else
                    System.out.println("The process of opening the device ended with error");
          }catch (UnsatisfiedLinkError ule) {
               System.out.println("BRUTAL ERROR: " + ule);
[stdout] The objeto already exists
[stdout] BRUTAL ERROR: java.lang.UnsatisfiedLinkError: OmronInit
Result: null
which indicates that this time I'm using the same instance of the singleton class created in the activation process, but that I cannot access the method. ANY HINT??

OEP install in Eclipse 3.4.2 fails with no repo for groovy bundle

I have Eclipse 3.4.2 on my Ubuntu box, and I tried to install OEP from <http://download.oracle.com/otn_software/oepe/ganymede> in the update manager.
It chugs for a bit, and then fails with:
No repository found containing: org.codehaus.groovy/osgi.bundle/1.5.7.20081120_2330
Any ideas on how to proceed with this?

David,
It's possible that the error you saw was due to a network glitch.
I just tried with a fresh install of eclipse-jee-ganymede-SR2-win32 with the update site you provided and it worked fine.
if you are interested we do have all-in one installers available with Ganymede SR2 + OEPE 1.1 or just the plugins zip which can be unzipped into the dropins folder at: http://www.oracle.com/technology/software/products/oepe/oepe_11g.html

WebLogic 12c and OSGi bundles ClassCastException error

When I deploy an OSGi bundle to WebLogic 12c there are no errors. However, when I try and access my application I get the following error:
java.lang.ClassCastException: com.sun.faces.taglib.jsf_core.ViewTag cannot be cast to javax.servlet.jsp.tagext.Tag
I suspect that WebLogic 12c is loading different versions of the JSF than what I have in my OSGi bundle but I am unable to confirm (I tried to deploy the wls-cat tool but I continue to get 503 errors even after a server restart).
My bundle currently uses JSF 1.1. After reading various forum posts, I have done the following but have not had any success:
1. Followed the steps in Re: jsf 1.2 on weblogic 12c (i.e. deploying the jsf-1.2.war, modified my weblogic.xml accordingly in my war and then deployed, etc)
2. Checked all of my manifest entries (which were correct) and even tried to set the required-bundles to my own JSF in the WEB-INF/lib directories
Are there any instructions/settings for having OSGi bundles work within WebLogic 12c? Note that my OSGi bundle works correctly in WebLogic 11.
Side question..I read that even though WebLogic 12c ships JSF 1.2 for backwards compatibility, it is deprecated for this release (as per http://docs.oracle.com/cd/E24329_01/web.1211/e21049/configurejsfandjtsl.htm#i163099). Does that mean that even if I get my bundle deployed/working that if there are other errors/issues in the future then I would not be supported? I am just trying to confirm so that I can make a decision about upgrading my JSF.
Thanks :)

gday -
WLS 12c (12.1.1) doesn't recognize OSGi bundles -- if you have a library you wish to use with your web application, then it needs to conform the packaging requirements for the Java EE deployment model you are using.
If you are getting conflicts with a WLS supplied library (JSF in this case it appears) then you need to specify a filtering classloader definition in a weblogic deployment descriptor so that the web/app classloader is instructed to ignore a specified set of packages/resources from the parent loaders and load them locally.
By way of an example, assume you have a web application in which you are bundling JSF 1.2 and you want to use this in place of the JSF 2.1 API/impl that is provided by WLS 12.1.1. In that case, you'd create a WEB-INF/weblogic.xml file and provide the following settings within in.
<weblogic-web-app xmlns="http://xmlns.oracle.com/weblogic/weblogic-web-app">
        <container-descriptor>
                    <prefer-application-packages>
                        <package-name>javax.faces.*</package-name>
                        <package-name>com.sun.faces.*</package-name>
                        <package-name>com.bea.faces.*</package-name>
                    </prefer-application-packages>
                    <prefer-application-resources>
                        <resource-name>javax.faces.*</resource-name>
                        <resource-name>com.sun.faces.*</resource-name>
                        <resource-name>com.bea.faces.*</resource-name>
                        <resource-name>META-INF/services/javax.servlet.ServletContainerInitializer</resource-name>
                    </prefer-application-resources>
        </container-descriptor>
</weblogic-web-app>Deploying that with your application, in which you have supplied the JSF 1.2 API and implementation jars in the standard WEB-INF/lib directory will direct WLS to use those locally supplied libraries instead of its JSF API/implementation.
Hope that helps.

Coherence 3.6 OSGI bundle

Is Coherence (version 3.6) OSGI bundle available? If not please point me to the link that documents coherence dependency information which i require while bundelizing coherence jar using a scaffolding tool. Thanks in advance.

Hi Yashas,
There is no OSGi bundle for Coherence available to download from OTN but you can use external tools like Eclipse IDE (creating plugins) or pax construct to convert coherence.jar to an OSGi bundle.

Is there way to use the 11gR1 JRF as an osgi bundle in 11gR2?

We've got a number of developers who want to use JDev 11gR2 for performance reasons, but we have to write software for 11gR1 Fusion Middleware. Is there a way to load the 11gR1 JRF and related dependencies as an osgi bundle? Or some other mechanism to accomplish the same? (Can I please have my cake and eat it too?)

No, I don't really have any documentation on it or anything. I just know that nothing like that exists :)

Are JUnit jar and spring OSGi bundle in OEPE compatible with each other?

The OEPE 11g comes with org.junit4_4.3.1 and Spring OSGi Bundle (org.springframework.bundle.spring_2.5.6.v200808081800.jar). However, these two seem to be incompatible. For example, @RunWith(SpringJUnit4ClassRunner.class) in a test case gives error because org.junit.internal.runners.JUnit4ClassRunner is not in the junit.jar.

Hello,
There could be a compatibility issue.
I mentioned in the other thread that downloading a more recent JUnit JAR and using it in your project might help us diagnose the issue further.
Let us know the results of that test.

Andrew

Coherence 3.5 as OSGi bundle

Hi,
We are starting out on an OSGi project which will use Coherence 3.5 as a data grid for storing and manipulating application data. I see that Coherence (as a separate product) is getting released as a Jar and not as an OSGi bundle. When I looked on the web, I see that Coherence (3.4) is getting packaged along with other Oracle products (CEP 10.3) as OSGi bundle (http://blogs.oracle.com/CEP/2008/10/oracle_complex_event_processin_1.html) and Oracle Fusion Middleware 11g.
Let us know if we can expect to see Coherence getting released as an OSGi bundle in the near future.
Till that time, Is there any guidance/recommendation on:
1) Running Coherence in OSGi environment
2) Accessing Coherence from an OSGi client application
Thanks,
Prakash

1. Generally, it's easiest if there is membership in only one Coherence cluster per OSGi container. In other words, one member of one cluster per container.
2. (From Stephen Felts, note that this was pre-3.5) Coherence currently uses the context classloader of the thread to find the default configuration file (coherence-cache-config.xml) and the JMX configuration (reports/report-group.xml). This is generally not the correct thing when running in OSGi. Applications will need to reset the context classloader before getting the class.
ClassLoader oldLoader = Thread.currentThread().getContextClassLoader();
ClassLoader newLoader = com.tangosol.net.CacheFactory.class.getClassLoader();
Thread.currentThread().setContextClassLoader(newLoader);
CacheFactory.getCache(cacheName); //Start coherence cache instance
Thread.currentThread().setContextClassLoader(oldLoader);"
{code}
3. (From Hal Hildebrand) There are issues that can come up specifically with respect to serialization with complex dependencies across bundles. Basically, OSGi allows classes to be hidden through the modules, so you have to be really careful as to the class loader you use for the cache. Here's a simple scenario showing the issue: Let's say that we're using the class loader from Bundle A. Bundle A imports the interface FOO from Bundle B. Bundle A uses an implementation of FOO, FooImpl, from Bundle C. However, Bundle C either doesn't import FooImpl (i.e. it's a private class) or Bundle A doesn't import the package from Bundle C. So, if you serialize FooImpl into the cache, what happen in the above scenario is that the cache will not be able to deserialize FooImpl using Bundle A's class loader.
4. There are various issues around the use of static fields in Coherence. These are very "non OSGI like". It's generally an issue when you are trying to create a Coherence bundle and decide what APIs to expose. Some of the "builder" work that went into 3.5 was designed to help rectify this and make Coherence easier to use in OSGi.
5. (From Jeff Trent, in lieu of having a Coherence bundle as part of the Coherence distribution) Bundlizing Coherence jar(s) is a prerequisite for using Coherence w/ OSGi. For this, you can essentially lift the bundles out of (e.g.) CEP. There are tools like BND (http://www.aqute.biz/Code/Bnd) integrated into Maven that really make this quite simple to do.
The summary I have so far is that using Coherence in OSGi is easy for easy stuff today, but there are a number of things that we're developing to make the more complex use cases simple in the future.
Peace,

[ERROR] could not find source for resource bundle modules.

We are in the process of upgrading our flex application from SDK3.6 to SDK4.5.0.17899.
Flexmojos version used for compilation is 3.9.
The flex library project is complied with SDK4.5.0 version but BUILD is not getting SUCESS from maven.
The following is the reason is showing and unable to find out the root cause.
[ERROR] could not find source for resource bundle modules.
Can you please help me out.
Thanks,

the 3.5 SDK directory
/usr/local/lib/flex_sdk/3.5.0/frameworks/locale/en_US
solves the problem.
Not sure why as the charts_rb.swc comes from Flex 2.0

Error: could not find source for resource bundle charts

I am trying to upgrade from Flex SDk 3.4 to 3.5.
I have copied the Data Visualisation SWCs under libs, locale and rlsls folders as suggested by adobe.
I get the following error when building the application
