I migrate from jboss3.0.6(jdk1.4) to jboss4.2.3(jdk1.5) GA,and most of the application functions can run . but i am puzzled for a big problem.My application can not call the servlet from applet. i had used "System.out.println" to export the information in the servlet's init and doget function . The same programe can run well in old enviroment!
What can i do ?
