Infinispan cannot work with XSLT transform?

[yfeng1998]

I have learned how to use distributed task service from example given at Need some example.

However, now I find out that Infinispan has some problem running XSLT transform in a remote server.

To set up example is easy, I added following lines to call() method in a DistributedCallable implementation:

    StreamResult result = new StreamResult(new StringWriter());

    TransformerFactory tFactory = TransformerFactory.newInstance();

    Transformer transformer = tFactory.newTransformer(new StreamSource("path to your XSL file"));

I did it in the example given in previous link.

When it executes, local server A runs fine but remote server B throw exception:

16:42:48,392 ERROR [org.infinispan.remoting.InboundInvocationHandlerImpl] (remo

e-thread-0) ISPN000260: Exception executing command: javax.xml.transform.Transf

rmerConfigurationException: Translet class loaded, but unable to create transle

instance.                                                                    

        at com.sun.org.apache.xalan.internal.xsltc.trax.TemplatesImpl.defineTra

sletClasses(TemplatesImpl.java:369) [rt.jar:1.8.0_25]                         

If server B runs first, then it runs fine but server A throws the same exception.

I am testing this with WildFly 8.2. But it appears to be an issue with running XSLT transformation in a remote Infinispan server.

Thanks for any help!

Hi, Infinispan does not have anything to do with XSLT transformations. This is probably a class-loading issue, but publishing whole stack trace would provide more useful information.

Hi, thanks for reply. It makes some sense since a similar error was reported at WildFly, the difference is that I only got the error when running from Infinispan. Here's the complete stack trace from the new StreamSource() line in above code:

09:09:43,318 ERROR [org.infinispan.remoting.InboundInvocationHandlerImpl] (remote-thread-0) ISPN000260: Exception executing command: javax.xml.transform.TransformerConfigurationException: Translet class loaded, but unable to create translet instance.

        [at the new StreamSource() line shown above]

Any suggestion for workaround would be appreciated, thanks!

PS. WildFly 8.2 is running Infinispan 6.0.2 version.
