Hi,
Using Class.forName() in OSGi always cause problem.
Seems you already figure out the solution, but I think you need add
dynamic import for jain-sip bundle.
Another solution is use fragment bundle which contain the classes
that jain-sip need init using Class.forName() and attach this
fragment to the jain-sip bundle, in this case the jain-sip bundle play
the role as a host and all resources in fragment is available for host.

We're using jain-sip 1.2 to develop a sip-bc and deployed to SMX4.3
without an error. Then we create an SA to start it.
While SIPReceiverEndpoint.start, SipFactory.createStack, we got a
PeerUnavailableException.
I wonder if Class.forName (aka Java reflection) does not work.
Here is a page talking about dynamic import.

Therefore, we added
<servicemix.osgi.dynamic.import>*</servicemix.osgi.dynamic.import>
to the
pom.xml of sip-bc.
Still got the same exception.
The following code is a snippet of SipFactory.java.
private SipStack createStack(Properties properties)
throws PeerUnavailableException {
try {
// create parameters argument to identify constructor
Class[] paramTypes = new Class[1];
paramTypes[0] = Class.forName("java.util.Properties");
// get constructor of SipStack in order to instantiate
Constructor sipStackConstructor = Class.forName(
getPathName() +
".javax.sip.SipStackImpl").getConstructor(
paramTypes);
// Wrap properties object in order to pass to
constructor of
// SipSatck
Object[] conArgs = new Object[1];
conArgs[0] = properties;
// Creates a new instance of SipStack Class with the
supplied
// properties.
SipStack sipStack = (SipStack)
sipStackConstructor.newInstance(conArgs);
sipStackList.add(sipStack);
String name =
properties.getProperty("javax.sip.STACK_NAME");
this.sipStackByName.put(name, sipStack);
return sipStack;
} catch (Exception e) {
String errmsg = "The Peer SIP Stack: "
+ getPathName()
+ ".javax.sip.SipStackImpl"
+ " could not be instantiated. Ensure the Path Name has been
set.";
throw new PeerUnavailableException(errmsg, e);
}
}
