I have installed Eclipse Heloios3.6 and Tomcat 6.0 and jdk 1.6.
Can you give the library files for struts and configuration file for struts namely struts-config.xml and web.xml?
While I tried to run struts, it shows the requested resource is not available error.
Assuming you mean Struts 2, did you have a look here: http://struts.apache.org/2.x/docs/home.html?
The core part of web.xml is this:
<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
<init-param>
<param-name></param-name>
<param-value></param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
Then there's a struts.xml in your classpath, not a struts-config.xml (although you might be able to configure the lookup).
