Problem with Ant Integration (and workaround)

[Bill Siggelkow <bi...@bellsouth.net>]

I recently had a wierd problem with the Cactus-Ant Integration.  I am using
the 1.6dev-20030907 ant integration jar.  Anyway, the problem I had was with
the "cactus" task (attempting to start Tomcat).  When I ran the Ant script
from within Eclipse it failed with the error "Couldn't find tools.jar ...".
However, when I ran the script from the command-line it worked fine.  I
traced the problem down to the getToolsJar method of the
AbstractJavaContainer class.  Basically, what this method does is try to
locate the "tools.jar" in the following location:

[java.home]/../lib/tools.jar

This works fine if "java.home" is pointing to something like
C:\j2dsk1.4.2\jre ... However when running in Eclipse my "java.home" was
C:\Program Files\Java\jre -- and, consequently, the tools.jar couldn't be
found.  My quick-and-dirty workaround was to create the following a 'lib'
folder under C:\Program Files\Java and copy the tools.jar there.  It seems
like the getToolsJar method could be made a little smarter to handle this
situation.

Thanks for the info, Vincent.  The "javac" task works for me under Eclipse
because I have included the tools.jar in the Ant runtime classpath
(Window->Preferences->Ant->Runtime) so the javac task must be using a
different mechanism to locate the tools.jar.  I will try and find the time
to take investigate this and submit a patch -- right now my 3-year-old wants
to color -- priorities :)

Hi Bill

This is a known problem in Eclipse :-) It's the same if you use the
<javac> task in Ant. It will fail under default Eclipse. Because, by
default Eclipse configures the JRE and not the JDK. I heard they're
going to change something in future versions.

That said, you're right, we should definitely improve the getToolsJar.
We'd be happy to get a patch if you have some time...

Thanks
-Vincent
