Deploying Servlet and JSP in Jboss/Jetty 3.0.4

[rikd]

Hi,

Am having problems deploying my test servlet and jsp in the jetty version of jboss. All works ok with the tomcat version - but i need to get it working with jetty...

Anyway...

BAsically I have a doPost in my servel as
public void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException {
RequestDispatcher dispatch;
ServletContext context;

try {
HttpSession session = request.getSession(true);
Greeting greet = (Greeting) GreetingFactory.getGreetingFactory().getGreeting();
session.setAttribute("greeting",greet);

context = getServletContext();
dispatch = context.getRequestDispatcher("/HelloWorldJSP");
dispatch.forward(request,response);

} catch (Exception e) {
throw new ServletException(e);
}
}

This should call me JSP which is mapped as follows in the web.xml


<servlet-name>HelloWorldJSP</servlet-name>
<jsp-file>HelloWorld.jsp</jsp-file>


<servlet-mapping>
<servlet-name>HelloWorldJSP</servlet-name>
<url-pattern>/HelloWorldJSP</url-pattern>
</servlet-mapping>

I put all this in my hello.war and deploy which works ok..

But as soon as I point my browser to http://localhost:8080/hello/HelloWorldServlet I get the following exception trace...

Which version of TC - this will let me know the Jasper version.

JBoss 3.0.x is still on Jasper 1
TC 4.1 (AFAIK) has moved on to Jasper 2 (so has Jetty 4.2 * JBoss 3.2).

This may be a difference in Jasper.

Please come back with more details.

The TC version is 4.0.3....

I used jboss-3.0.4 with jetty and jboss-3.0.0 with tomcat 4.0.3...

I've found a work-around:
In web.xml add a terminating "/" in the "url-pattern" tokens, e.g. <url-pattern>/errorpage.jsp/</url-pattern>

The problem is in JspServlet.java; loadJSP:
if( outURI.endsWith("/") )
outURI = outURI + jspUri.substring(1,jspUri.lastIndexOf("/")+1);
else
outURI = outURI + jspUri.substring(0,jspUri.lastIndexOf("/")+1);;
The jspUri.lastIndexOf() causes the exception!
I haven't gone further to find out why, and I don't know if the work-around is a good idea, - but it got me up and running!

Ytru the 3.2 series, it uses Jasper2, which is possibly the same version you had in your Tomcat distro.

If it works, but you need 3.0.x for other reasons, simply copy the jasper jars from one jbossweb.sar to the other.
