"jbosssx-client.jar" can be found in your JBoss server in the directory "client". And it should be much newer than 2007.
Probably "www.java2s.com" contains a much older file from an earlier version than 5.0Beta2.
yes you are right, but here's my problem:
if I take the Jboss5.0 version of jbosssx-client.jar, the program can't find the class and if I take the older version from 2007 I get
[javac] F:\Entwicklung\JBoss_5.0\jw-0215-ejbsecurity\example\src\main\com\mkeym\customsec\ejb\TradingAccountSecurityProxy.java:22: com.m
keym.customsec.ejb.TradingAccountSecurityProxy is not abstract and does not override abstract method
So this doesn't fit some how.
My question is, where can I find the jboss5.0 version of a jar that keeps the SecurityProxy class that fits.
give "jbosssx-as-client.jar" a try, this one contains your class in 5.0.1.
