Re: help with sample application

Same error even if I edit global web.xml. The jar files are in TOMCAT_HOME/common/lib which is also in my classpath.

I tried another thing, which was placing a cactus.properties in my home directory than the error changed. Now I get this:

My classes are like this:

import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;

public class SampleServlet extends HttpServlet
{
   public void saveToSession(HttpServletRequest request)
   {
       String testparam = request.getParameter("testparam");
       request.getSession().setAttribute("testAttribute", testparam);
   }
}

import junit.framework.Test;
import junit.framework.TestSuite;

import org.apache.cactus.ServletTestCase;
import org.apache.cactus.WebRequest;

public class TestSampleServlet extends ServletTestCase
{
   public TestSampleServlet(String theName)
   {
       super(theName);
   }

   public static Test suite()
   {
       return new TestSuite(TestSampleServlet.class);
   }

   public void beginSaveToSessionOK(WebRequest webRequest)
   {
       webRequest.addParameter("testparam", "it works!");
   }

   public void testSaveToSessionOK()
   {
       SampleServlet servlet = new SampleServlet();
       servlet.saveToSession(request);
       assertEquals("it works!", session.getAttribute("testAttribute"));
   }
}

I thought that since the jar files I am using to compile the cliente are the same that are on the server, I wouldn't get an error like this. I've seen this kind of error when you compile the classes with one version of the library and try to execute it with another version.

Thanks again.

Hi Kelly,

On http://jakarta.apache.org/cactus/integration/howto_tomcat.html, it says
to edit the global web.xml but you said you have created a web.xml in your
webapp. Can you try to do exactly as described on the page and see if it
works?

Where have you put the cactus jars (commons-logging, aspectjrt, cactus,
etc)?

What is the name of your war (more specifically have you named it "test")?

Thanks
-Vincent

PS: We'll get it to work, no worries... ;-)

Sorry for the lack of information....

The web.xml is as follow and is located in my application WEB-INF
directory:

<web-app>

<servlet>
 <servlet-name>ServletRedirector</servlet-name>
 <servlet-class>
   org.apache.cactus.server.ServletTestRedirector
 </servlet-class>
 <init-param>
   <param-name>param1</param-name>
   <param-value>value1 used for testing</param-value>
 </init-param>
</servlet>

<servlet>
 <servlet-name>ServletTestRunner</servlet-name>
 <servlet-class>
   org.apache.cactus.server.runner.ServletTestRunner
 </servlet-class>
</servlet>

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

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

</web-app>


The page I was referring to is this one:

http://jakarta.apache.org/cactus/integration/howto_tomcat.html

I'm trying to follow this example.

Thanks

Kelly

Hi Vincent,

yes it is a 404. I copied and pasted the web.xml that is in the example
page. I 'm wondering it is a problem with my tomcat version. I'm using
tomcat 5.0.27

What web.xml? The global one or the one in your war's web-inf/Web.xml?

Could

you show us your web.xml?

Could you also tell me what example page you are referring to?

There should be no pb with your Tomcat install.

Thanks
-Vincent

Hi Kelly,
What error are you getting? A 404? If so it means your mapping in

web.xml

is

not correct. If it's a 500 error then your tomcat logs should have the
error.

Thanks
-Vincent

PS: Could you please tell me what Cactus page you are referring to? If
there's something to fix in the doc we need to know where it's not well
explained.

Subject: help with sample application

I'm trying to run cactus sample application as is explained in cactus
page. But I get this error: _The requested resource
(/test/ServletTestRunner) is not available.
_The url I'm typing is

http://localhost:8080/test/ServletTestRunner?suite=TestSampleServlet

I'm using tomcat 5.0.27 and java 1.4.2_04

I already tried placing the libs in common/lib and in webapps/test/lib
without results.

All the requested libraries are also in my classpath

Could anyone help me?

Kelly.
