Hallo all,
I wrote a servlet example under Tomcat
early. Now I want to run it with Soap.
How can I convert this servlet under
HTTP into SOAP, i.e how can write a client and server
programs?
I installed Tomcat und apache-soap 2.3.1.
It works.
Another question: can I change
the predefinded web.xml under
\jakarta-tomcat-4.1.30\webapps\soap\WEB-INF,
if I want to call another url also with
soap protocol for instance http://localhost:8080/Wins/RequestParamExample3.
I tried to change the servlet name and
servlet mapping in web.xml under soap. For example replace
<servlet-class> org.apache.soap.server.http.RPCRouterServlet
and <servlet-mapping>
/servlet/rpcrouter. But everytime after editing the tomcat server can't
run.
Why servlet in Tomcat without soap can call
arbitrary URL, only you should put your java class in
webapps/your-Servletname/WEB-INF/classes
and edit your web.xml to set the servlet name and
servlet class and mapping. Why is the url in soap web-application in client
program always http://localhost:8080/soap/servlet/rpcrouter.
The following is web.xml
under webapps\soap\WEB-INF and my
sevlet program RequestParamExample3.java
