Question

I’m trying to use MessagePack in a WAR application in Glassfish, but I’m getting this exception (although JavaAssist already is a library of the project):

java.lang.NoClassDefFoundError: javassist/ClassPath at
org.msgpack.template.builder.BuilderSelectorRegistry.initForJava(BuilderSelectorRegistry.java:58)
at
org.msgpack.template.builder.BuilderSelectorRegistry.(BuilderSelectorRegistry.java:38)
at
org.msgpack.template.TemplateRegistry.(TemplateRegistry.java:38)
at org.msgpack.MessagePack.register(MessagePack.java:149)

this happern When I call

org.msgpack.MessagePack.register()

Any ideas?

Answer 1

I posted the error in the MessagePack’s JIRA and this is the answer:

I added this libraries to my classpath:

javassist.jar msgpack-0.5.2-devel.jar slf4j-api-1.6.2.jar
slf4j-ext-1.6.2.jar slf4j-simple-1.6.2.jar

Copying them directly to the lib folder of glassfish, to: C:\Program
Files\glassfish-3.1\glassfish\domains\domain1\lib

I’m gonna work now in adding them as part of my war

Thank you very much again.
