Hi,
Really hoping someone can help me, long story short I have a bundle that
wraps apache axis and under JRE1.4 everything worked fine. However I've
since upgraded to JRE1.5 which happens to include
javax.xml.namespace.Qname that is causing a java.lang.LinkageError when
trying to call a webservice in a plugin. After researching I realized the
issue is because axis also has an implementation of the same class but
when instantiated from a client plugin its getting loaded from the JRE.
OSGI and ClassLoading is a sore spot for me but what I think needs to
happen is to somehow say "in this plugin that is creating a webservice
call, whenever it instantiates a new Qname class use the class provided in
the axis plugin and not the one in the JRE" Atleast I think that is what
needs to happen. Can anyone offer some suggestions? - Duncan

Bill, a couple of good things have happened over the last few days, one I
just got my scuba certification in Belize and saw some great things
including a couple of sharks, and secondly (more importantly) I followed
your lead and added a version tag to the package so that it now loads the
right class. Thanks so much, this one would have taken me a long time. -
