Websocket connection failed

Hi,

I'm trying to develop an application based on websockets in the Netweaver Cloud.

My tests on Tomcat 7 were successfull but in the cloud the connection failed.

At the moment its a small test application with two files.

One html-file to open the connection and a servlet to manage the connections. The servlet extends the WebSocketServlet in the org.apache.catalina.websocket package. With "'ws://' + window.location.host + '/WebSocket/socket'" the connection will be opened.

And in the web.xml is the following entry:

  <servlet>

    <servlet-name>Server</servlet-name>

    <servlet-class>socket.Server</servlet-class>

  </servlet>

  <servlet-mapping>

    <servlet-name>Server</servlet-name>

    <url-pattern>/socket</url-pattern>

  </servlet-mapping>

It works on local Tomcat 7 Server, but when I deploy and test on Netweaver Cloud I get the following exception:

HTTP Status 500 -

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

Has someone an idea what I could do?
