<div>To whom may still be interested in this NK 3 issue ;-) I finally did found out what caused the java.lang.LinkageError: loader constraint violation: loader (instance of com/ten60/netkernel/module/ModuleClassLoader) previously initiated loading for a different type with name "javax/xml/namespace/QName" also happens with "javax/xml/namespace/NamespaceContext". It turns that its problematic if multiple of these classes exist in the dynamic classpath. (I was sure I checked this before, but I must have made errors then.) If you delete them from the following jars in ext-xml-core: (1) xbean.jar and (2) xmlpublic.jar. (You''ll have to open up the ext-xml-core jar to get at those and repackage lateron, also don''t forget to remove the old jars from the lib/expanded directory.) I found out due to a new set of accessors (sorry, still can''t move on to NK 4 :-( ) I was creating which relied on libraries who also included these java.namespace classes. And it resolved my problems by making sure that they actually only exist in the endorsed xml-apis.jar. (I also tried the other way around, i.e., removing them from the endorsed jar,  but that didn''t help. Probably in that case it gets them from some default location also.) I assume it also solves the cold restarts where this linkage error would also pop up. Greetings, Menzo</div>

To whom may still be interested in this NK 3 issue ;-)

I finally did found out what caused the java.lang.LinkageError:

also happens with "javax/xml/namespace/NamespaceContext".

If you delete them from the following jars in ext-xml-core: (1) xbean.jar and (2) xmlpublic.jar.

May 16, 2009 22:16NK4 changes to the classloader

It''ll be interesting to see if NK4 sorts this problem out. The only reason for this problem that I can see is that classloading is supposed to be synchronized and part of NK3 classloader wasn''t for performance reasons. This could lead to the case of a classloader saying something wasn''t loaded and then when the load was attempted is was now there. We''ve now tightened this up.

May 16, 2009 20:51Problem on Solaris

We consistently get this problem with our code on Solaris after a cold restart - both for my personal NK project and the deltaxml web site.

I''ll try and create a more specific reproduction of the problem.

We''re currently looking at this as we are trying to configure Team City for continuous integration with my NK house billing app.

Hi Gabriel,

Indeed I''ve seen both problems before ;-)

The first one happens (from time to time/always?) when you do a hot restart of the server. Tony also had a look at it once, but until now we haven''t been able to resolve it. My ''solution'' is currently that I always do a full restart of the server when needed.

The second is as Peter described. You are requesting an XML aspect for an XSLT document that has already been compiled into a Tranformer aspect. That aspect can''t be transrepted back into an XSLT document.

So for now I only see a solution for the second problem, i.e., by linking the XML aspect to the Transformer aspect so a Transformer aspect to XML aspect transreptor can just return that aspect.

The first problem would need a new quest for its actual cause ...

Hope this helps (a bit),

Menzo

Hi Gabriel,

Second problem first. Looks like you are trying to use a variable as XML that has already been transrepted to an XSLTTransformerAspect - ie it must be a stylesheet? Can you make a reference to the original source rather than the variable? If you can show some of the code that would help.

First problem - can you post your module.xml where this script is declared. It looks like the class is being loaded using another classloader prior to this transreptor trying to use a module classloader.

Menzo is the expert on this xslt2 library - if we''re in luck he might have seen this before ;-)

Cheers,

Peter

<div>We are having trouble using the xslt2 accessor in netkernel 3.3.1 via DPML as outlined @ http://www.1060research-server-1.co.uk/docs/3.3.0/book/developerreference/doc_ura_xslt2.html. Below you''ll find the error we are getting.  Any assistance would be greatly appreciated.
