I am using MyEclipse 8.6 on Windows 7 64-bit OS.

I have recently started using JAXWS to create a web service in my web application which I run and debug in the integrated/sandbox Tomcat server.

I provide the JAXWS JARs (version 2.1.7) in my WEB-INF/lib folder as recommended.

However, sandbox Tomcat seems to insist on loading XFire JARs before my own JARs and this results in a ClassCastException when launching the WSServletContextListener.

I believe the problem is in the .metadata\.me_tcat\conf\catalina.properties file which is being told:
shared.loader=${catalina.home}/../../com.genuitec.eclipse.ws.xfire_8.6.1.me201011040812/lib/*.jar

Removing this entry or emptying its value only results in it being automatically re-added the next time I launch Tomcat.

The only thing that appears to fix the problem is if I delete all JAR files from the specified MyEclipse XFire lib folder.

There are many other developers in my department that work on this code and I can't ask them all to mutilate their MyEclipse installation so that we can implement a web service.

Is there another solution that I might be missing?

Does it make sense to automatically include JAR files for XFire for all web applications whether or not the developer wants to use them? And especially if they can't override them?

Thanks in advance.

jmrobichaud ,

Sorry that you are seeing this issue. I have escalated it to a dev team member. They will get back to you.

jmrobichaud,

I couldn't replicate your problem. If the application includes jars in its lib folder, they should always be picked up first, when running application code. I had thought that you might have another web service application deployed which didn't have a JAX-WS jar file in the lib folder and so Tomcat loaded the one we supply, via the shared.loader property. However, I couldn't replicate that situation though it may be worthwhile checking this.

Of course, you can always test on an externally installed Tomcat installation (which can be configured and launched from MyEclipse), if necessary but I can't see that it should be necessary.

So please check that there are no other deployed applications that might be causing the problem you see. If there aren't then can you try to create a minimal project that exhibits this behavior and send it to us, so we can try to replicate here?
