Add .jar file into Tibco Designer

I want to use my class methods into TIBCO Designer(5.6) project. I expor开发者_如何学编程t my Java project into .jar with my Eclipse Indigo. Then I create AliasLibrary in the Desinger and add the .jar. But after I create Java Method add click to choose Class, I click on my .jar file in Class Path Archive List field and Package / Class list is empty. Can anyone help me?

Try compiling it to the same target Java version as TIBCO Designer/BW is using. Usually TIBCO will use its own JRE, not necessarily the latest/the one you've installed if e.g. you've installed the JDK.
