Here's some information to give you some hints, some possible things to explore, but I doubt it will help directly.
You don't say what version of equinox, or VM, you are using, but if it is pre 3.6 M2, I'd suggest you try with the latest milestone just to see if it works. I say this because in 3.6 M2, Bug 285505 was fixed which _might_ be indirectly related. https://bugs.eclipse.org/bugs/show_bug.cgi?id=285505. Especially if it does solve your problem, and you need to use a released version, you can employ a work around in your own code, by using the threads threads context classloader. Something like Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader()); _before_ your code calls (directly or indirectly) SOAPPartImpl. (with all the right resets/trys/finallys, etc.) But this type of problem is pretty complicated, and depends on many things (e.g. which JVM you are using, which and how many versions of "Node" you have on your classpath, how and where orasaaj.jar gets its version of 'Node'). There's quite a few things on the internet that describe or address the issue in different contexts, one such example is http://www.ibm.com/developerworks/websphere/library/techarticles/0310_searle/searle.html . But, I think, its fundamentally a DOM implementation and JVM issue, and OSGi just finds the problem early, before it gets to a runtime problem? But, you say it happens while "trying to build a bundle" so if you mean that literally ... then my advise won't really help at all (since it is a runtime solution). In any case, I hope the information gives you some things to look at, or to frame the question more precisely.

I trying to build a bundle,when deploy into osgi and run,it throw an error: java.lang.LinkageError: loader constraint violation: when resolving overridden method "oracle.j2ee.ws.saaj.soap.SOAPPartImpl.appendChild(Lorg/w3c/dom/Node;)Lorg/w3c/dom/Node;" the class loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) of the current class, oracle/j2ee/ws/saaj/soap/SOAPPartImpl, and its superclass loader (instance of <bootloader>), have different Class objects for the type org/w3c/dom/Node used in the signature, the oracle.j2ee.ws.saaj.soap.SOAPPartImpl is in orasaaj.jar and it is used by parlayX,I found that the orasaaj.jar and rt.jar both have this class SOAPPartImpl, To solve this problem ,what do I have to do, in addition, it is normal and successful that the project just run as a application , Many Thanks Fox_______________________________________________ equinox-dev mailing list [email protected] https://dev.eclipse.org/mailman/listinfo/equinox-dev
