[jelly] howto setup eclipse for jelly development?

["Wannheden, Knut" <kn...@paranor.ch>]

Hi,

I was wondering if someone could provide some easy instructions on how to
best set up Eclipse for development on the Jelly project.

I suppose the first step is to check out Jelly as a Java project from CVS.
This part is quite easy.

The next step is probably to setup the project classpath using the Maven
definitions, which is very well explained in
http://radio.weblogs.com/0112098/stories/2003/02/12/usingEclipseAndMaven.htm
l.

Now comes the harder part: Now that Jelly has been modularized into the core
and the individual tag libraries (all as individual Maven projects) I don't
know how to best map these to Eclipse projects.  Should I create a single
Java project for everything?  Or should I create individual projects for the
tag libraries?  For the former to work, I assume I will have to setup the
classpath and sourcepath manually, which isn't very elegant.  And for the
latter to work I assume I will somehow have to use a different root
directory for the Jelly core project as projects can't be nested in Eclipse.
Also I guess I'd have to setup the project dependencies manually.

Hopefully there's a much easier solution altogether! :-)

Cheers,

What I've been doing locally is to add all the source directories for each
library I'm working on to the project along with manually adding any extra
jar dependencies. So I have a single project with all the source code for
Jelly in there, divided into java & test directories for each library. Then
I get the benefit of eclipse compile checking if I change something in
Jelly's core etc.

It'd be nice to patch the eclipse plugin for Maven to do this automatically.
The same thing could be used to generate the eclipse project for Maven
itself; it has a similar issue of lots of sub-projects (plugins) that it'd
be nice to include in the same large project.

Hi guys,
Here is the scenario

* JDBC Driver: Oracle's
* API: PersistancBroker
* Context: Tomcat 4.0
 
While loading the application, I get an exception stating ...

But when I use MYSQL, it works quite fine.
 
Any idea?
