hello all,

I have made a simple hello world web service in Eclipse with Tomcat,
Running from Eclipse with the clients works fine, but when that I try to
run it on another server an access it from there I got this exception:

---------------------------------------
HTTP STATUS 500

type Exception report

message

description The server encountered an internal error () that prevented it
from fulfilling this request.

exception

org.apache.jasper.servlet.JspServlet.service(JspServlet.java :272)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

I have transfered the web.xml file and lib and classes folder in a WEB-INF
folder and also all the JSP files(Input,Method,Result,TestClient). The
Methods and Input sections of the client display is fine. However, I
received the error in the Results section of the client.

Does any one have any idea what could be the problem?

thanks a lot
Mitra
