Hi all
This problem has been driving me crazy and I know that it should be a
simple problem. I have already posted this in this mailing list, but a
simply configuration issue is stopping my development work!! Please help.
There is a reason why I post this in the struts mailing list because a
non-struts web application works fine with Eclipse WTP.
I have written the simplest struts-enabled HelloWorld application. It
works fine if I deploy it directly to the Tomcat server. But I get a 404
error while configuring it with Eclipse WTP.
Below is my configuration:
Java - 1.4.2_13
Tomcat 5.5.23 with Java 1.4 compatible jars
Struts 2.0.6 with Java 1.4 compatible jars
Eclipse WTP 3.2.2
I created a new "dynamic web project" with Tomcat 5.5 as runtime, "test"
as "context root" and "WebContent" as "Content Directory". I copied the
struts jars to the "WebContent/WEB-INF/lib" folder. The jsp files are
placed in "WebContent/WEB-INF/jsp" folder.
The following is my folder structure:
+ WebContent
- + WEB-INF
- + classes
- struts.xml
- + jsp
- + lib
- + src
- web.xml
Following are my codes:
web.xml

<title>Hello World!</title>
</head>
<body>
<h2><s:property value="message" /></h2>
</body>
</html>
When I run the application by using "run on server" option, the tomcat
server starts without a problem and opens the url "http://localhost
:8080/test/" in the browser. "http://localhost
:8080/test/HelloWorld.action" gives a 404 error. But the same application
deployed directly in Tomcat, works fine!!
Please help.
Thanks
