Trying to run an Apache Turbine servlet as a J2EE project [message #189241] Tue, 06 March 2007 17:46 Go to next message

I have a webapp that uses the Apache Turbine framework. So that
framework provides the servlet class, not my webapp. I cannot find a way
of running it using web tools and attached to a Tomcat server instance
setup in Servers. I need to get it running here to be able to use the
Profiler, as I have up until now used the sysdeo plugin, but there seems
no way it will work with TPTP. Neither will TPTP work with the Agent
controller and an independently running Tomcat. It stops Tomcat running
adding the JVM arg required. Web tools seems to cater purely for JSP
application with their own Servlet class, is this right?

Is there some documentation on setting up Web tools to work with any
sort of framework like Turbine or Spring?

Thx.

I should point out that when I do try to run the Turbine webapp under
the Tomcat 5.5. server on localhost (Run modules directly from workspace
is unchecked)

I added the turbine jar ( with the servlet class) into the classpath and
the turbine src directory into the server configuration too.

My VM args are

-Dcatalina.base="D:\Tomcat_5.5" -Dcatalina.home="D:\Tomcat_5.5"
-Djava.endorsed.dirs="D:\Tomcat_5.5\common\endorsed"

I get this.

I found that because I had included the Turbine jar in the classpath it
caused the clash as it also uses log4j. But removing that means it can
no longer find the servlet class supplied by that very same Turbine jar.
Looks like catch 22 to me. Now I have removed that and I get

Can someone at least tell me that Web Tools will not run with a Apache
Turbine webapp? I don't have enough knowledge to determine this and I
feel like I am wasting my time.

I'm not familiar with Apache Turbine, but is there a reason not to
include the jar(s) in WEB-INF/lib? As far as I know, "setting up a
framework" is just a matter of including in the Dynamic Web project what
is needed per the requirements of the framework.

With respect to TPTP, there are a couple of bugs affecting profiling use
with WTP servers, Bug 174863[1] for WTP 1.5.3 and Bug 174886 for WTP 2.0
M5. You haven't mentioned with versions of Eclipse and WTP you are
using, so I can't say if they apply. If you have th TPTP SDK for
profiling, it's fairly easy to patch TPTP to get it working with WTP
1.5.3 and WTP 2.0M5.

I assume the VM argument you are referring to is "-XrunpiAgent", which
is what TPTP silently adds. To help the piAgent to be found, I add a
"PATH" environment variable to the launch configuration that includes
the path to the directory containing the piAgent.dll in TPTP, i.e. the
directory for the org.eclipse.hyades.execution.win32.x86_??? plug-in.
If the piAgent isn't found when executing Profile on server, then Tomcat
won't start.

Cheers,
Larry
