Hello everyone,
I'm currently having a problem; in essence, as in the title, is about JSPs with
JDK5.0 features that do not compile.
I'm running JBoss 4.0.3 SP1 with the default integrated Tomcat 5.5, with JDK5.0.
I wrote a very simple JSP in Eclipse 3.1.2 with the JBoss IDE 1.5.1 GA,
packaged and deployed into JBoss. There is no problem with starting JBoss or
deploying the WAR. This is the JSP:
<?xml version="1.0" encoding="UTF-8" ?>
| <%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
| <%
| java.util.Vector<String> v = new java.util.Vector<String>();
| %>
It's just the declaration and definition of a Vector using JDK5.0's generics
feature.
However, when I tried to access this JSP through the browser, I get this error:
02:14:15,000 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception
| org.apache.jasper.JasperException: Unable to compile class for JSP

| An error occurred at line: 3 in the jsp file: /index.jsp

Ok, this basically means that the compiler did not recognize the JDK5.0
features. I had already set the following options in Tomcat's conf/web.xml file:
<servlet>
| <servlet-name>jsp</servlet-name>
| <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
| <init-param>
| <param-name>fork</param-name>
| <param-value>false</param-value>
| </init-param>
| <init-param>
| <param-name>xpoweredBy</param-name>
| <param-value>false</param-value>
| </init-param>
| <init-param>
| <param-name>compilerSourceVM</param-name>
| <param-value>1.5</param-value>
| </init-param>
| <init-param>
| <param-name>compilerTargetVM</param-name>
| <param-value>1.5</param-value>
| </init-param>
| ...
| </servlet>
It still does not work, it does not compile.
I did search Google for any possible solutions but to no avail. For some reason
it seems as if no one encountered it before; either I'm not searching properly
or there are no articles on this issue. I did find a thing about Tomcat
versions prior to 5.5.16 (this issue was fixed in 5.5.16):
http://issues.apache.org/bugzilla/show_bug.cgi?id=38389
The problem was regarding the compilerSourceVM and compilerTargetVM as
mentioned above.
However, I'm very sure that the version of Tomcat that came with JBoss 4.0.3
SP1 is not 5.5.16, although I was unable to find which version was it.
I believe if I were to integrate Tomcat 5.5.16 into JBoss, the issue might be
resolved. However I'm unable to find any such tutorial or resource to
accomplish this on Google.
Another note is that I'm unwilling to use JBoss 4.0.4 RC1 because there is a
bug with EJB3's TransactionManager (yes, I'm using EJB3; RC5 integrated into
default server configuration):
http://www.jboss.com/index.html?module=bb&op=viewtopic&t=78114
Basically I'm stumped. Tried all I can. Can anyone please tell me how to
resolve this issue in JBoss 4.0.3 SP1? Please direct me to any existing
resolutions, if any. I would also appreciate links to articles that describe
how to integrate Tomcat 5.5.x into JBoss. Thanks!
