i'm calling an ejb 3.0 bean and it partualy seems to work but ....


String value =bean.myroutine(String abc);
works perfectly

changing the bean definition to .....
myroutine( myclass xxx)
does not offer any construction error But fails with a runtime error

class myclass
{String aaa="dassd";
String bbb="sdsds";
}
xxx=new myclass();
String value=bean.myroutine2( xxx)
// obviously all bean interfaces are addapted to myclass instead of String

ps: as I Use Dom4j.Document as class it works fine
just my classes do not seem to work !!!!???

fails with
javax.ejb.EJBException: java.lang.IllegalArgumentException:
Wrong target. class com.bean for public java.lang.String com.cyclus.bean.myroutine2(xxx)

It seems to simple for me not to make a mistake.
