Hi,

I am new to ECF, and when I try to create a container using following code:

IContainerFactory factory = ContainerFactory.getDefault();
IContainer container=factory.createContainer("ecf.xmpp.smack");

I get following error on second line at factory.createContainer("ecf.xmpp.smack)" :
"The type org.eclipse.ecf.core.identity.ID cannot be resolved. It is indirectly referenced from required .class files"

I don't know why. I have checked the target platform and the ECF sdk is added there.
Can you please help to fix this issue?

I am using Ecliple Juno Release 1, with ECF 3.5.6.

Hi Nadeem,

The call also involves that ID class. You need to add the bundle or package that exports this ID class. Add it to "require bundle" or "import package".

Regards,

Wim

Hmmm...this is very strange, as org.eclipse.ecf.core.identity.ID class is declared in org.eclipse.ecf.identity and is used throughout nearly all of ECF.

I can't currently reproduce it...using a very similar piece of example code in this class

http://git.eclipse.org/c/ecf/org.eclipse.ecf.git/tree/examples/bundles/org.eclipse.ecf.example.clients/src/org/eclipse/ecf/example/clients/XMPPChatClient.java

One thing that might be going on with your code...is that perhaps it's running as a java application rather than a plugin? i.e. How are you invoking this code? Is it in a main method? Or is it part of an Eclipse/OSGi Application? Because of OSGi's classloading model, it's necessary to run your code as an Eclipse/OSGi Application...because then the appropriate class namespace is setup (including the org.eclipse.ecf.identity.ID class and others).

Please let us know and I'll help diagnose further.

Dear Wim and Scott,

Thank you very much for your kind support.

I have fixed the problem by following Wim's instructions to add the package (org.eclipse.ecf.core.identity) that exports ID class to the "imported packages" list. I was considering ID class to be a part of org.eclipse.ecf.core package.

@Scott it was a plug-in project and I was getting compile time error. Thanks a lot for your kind consideration and reply.

Best regards
