Problem (Exception) while integrate SIP into OSGi Framework

Dear Developers,

I have created a simple sip application (java based) that successful send the REGISTER and INVITE packet to the proxy server

Currently I tried to integrate this simple application into an standard plug in service with OSGi framework (with eclipse) to implement in Knopflerfish osgi framework environment.

When I try to initiate the SIP service, it throws this exception:

Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: javax/sip/InvalidArgumentException

Can anyone help me? Or probably could tell me what's the problem?

Thanks a million in advance.

It could not find javax/sip/InvalidArgumentException, have you added classpath correctly?

First of all, thanks for the reply.
You meant the program cannot find the "javax/sip/InvalidArgumentException"?
I have added the library into the project library.
Which classpath do you meant?

I don't really know, because lately I'm not working on OSGi.
But you have to make your bundle is able to find SIP library at run-time.

You should take a look at run configuration screen (I don't know what tool are you using, but it should have one), there should be something like Run-time library.

I am currently using the eclipse to develop the application and plug-in.
Do you have any idea where it is placed on?
Do you meant the project properties -> Java Build Path -> Libraries ?
Is that exception error based on the configuration? Not on my coding?

No, not Java Build Path, that is for compile time. I believe this happened because improperly configuration, it has nothing to do with coding.

How do you run the application? I think you can find configuration about Run-time Libraries in a tab in that dialog .

I don't know much about SIP, but I do know that you have a NCDFE on javax.sip.InvalidArgumentException.

In OSGi, that probably means that your bundle doesn't import the javax.sip package. Honestly, I almost never lean on the Eclipse PDE to handle this work for me, so I am a bit fuzzy on what you'd need to do with regard to Eclipse PDE...but breaking it down to bare OSGi, you'll need an "Import-Package: javax.sip" in your bundle's manifest. How you get that there can be done a number of ways, depending on your development model.

I use things like BND and Pax-Construct...they're awesome at handling this kind of detail for me. But in PDE...I'm not so sure. Sorry that I can't help more in that regard.

Thanks everyone for helping me resolve this problem.
It is been resolved.

We need to add the library at the OSGi Manifast file
so that it can be found.

Thanks for the update.
