Hi
Has anyone solved this problem. I been working on this problem since days. I set the soap.jar files and jwsdk etc in the systems environment variables as well. I am using java sdk 1.4.But I dont know what is wrong my browser wont display the applet ifI use soap in it,if I leave the soap part the browser displays it.
