"Jasper 2 JSP Engine How To" ant script - ServletException not found
Hello,
I've been trying to follow the "Jasper 2 JSP How To" located at
http://tomcat.apache.org/tomcat-5.0-doc/jasper-howto.html
to compile a sample JSP, but I'm running into the error
BUILD FAILED
E:\workspace\progsoftware\trunk\source\jasper\build.xml:5: taskdef A class needed by class
org.apache.jasper.JspC cannot be found: javax/servlet/ServletException
I'm using the ant script provided in the Howto as-is. For the JSP, "process.jsp" I use
<html>
<head></head>
<body>
Jasper
</body>
</html>
since this is only an educational demo. I do not think the problem is with the JSP since the error
occurs on line 5, which is a taskdef that does not mention the jsp.
My setup is Windows XP SP2, Tomcat 5.5.15 (I also tested with 5.5.12 with the same result), and
Ant 1.6.5. The Tomcat distributions I used were the Windows binaries with installers.
My command line, adapted from the Howto, is
ant -Dtomcat.home="C:\Program Files\Apache Software Foundation\Tomcat 5.5"
-Dwebapp.path=E:\workspace\progsoftware\trunk\source\jasper
webapp.path is the working directory, target directory, and source directory, since I want to keep
things as simple as possible while getting everything working correctly.
To make sure the path are set up correctly, here are some directory listings.

I've tried the following so far
1) reverting to an older version of Tomcat, as mentioned above.
2) several Google searches, including "servletexception jasper2", but no dice
3) rewriting the build script, based on a forum discussion at
http://www.experts-exchange.com/Web/Web_Languages/JSP/Q_21567260.html, although I embellished a
bit:

Glen, thanks for the suggestion on the search terms. After reading some search hits, I copied all
the jars in TOMCAT_HOME\common\lib to ANT_HOME\lib and everything works now.

Well, I just did a Google search on "taskdef A class needed by class"
(with the quotes, of course) and got 239 hits. You'll probably find
your answer somewhere in there.

Glen, thanks for responding. I placed both the property and path element references to servlet-api
at the beginning of their respective sections, and defined jdk.javac.path. I still get the same
error.
Any ideas on why build.xml provided by the Tomcat website doesn't work?

Of course, it looks like it can't find javax.servlet.ServletException
while building. This is kept in servlet-api.jar.

jdk.javac.path doesn't seem to be defined anywhere--that may be a
problem. Also, I'm unsure if it matters, but ${servlet.api} is listed
last in this set, so the Jasper libraries listed earlier may not be able
to find it, and hence may not be able to see the ServletException class.
I would move servlet.api before the jasper references.
