Library in dynamic web application [message #173092]

I am developing a web application that is based on other java projects
that hold some base classes. Additionally these base projects depend on a
Library that is installed as plugin in eclipse and provides JAR's as a
Library in the classpath of the base project.

How can I add this library to the classpath of the web application? Though
the base project exports the library and is included as a J2EE Module
Dependency the library is not loaded when I start the application.

In J2EE Module Dependencies, you can use the "Add External JARs..."
button to include these kind of JARs in your web application. This
would involve specifying the full path to the JARs in the plug-in. You
could also use the "Add Variable..." button and define a variable that
covers most of the path to the plug-in. Then reference the JAR from
that variable.

Cheers,
Larry

Thanks for your anwser. This would be a workaround to solve my problem.

Will it be possible to include libraries in the future? Is there a feature
request in the bug database?

cheers

You cannot add a library and that stinks.
If you add a variable it will barf.
It only works if you add a jar directly. That stinks too.

I'm not aware of a specific bug with this feature request, though I
believe there are some that imply that populating the web project's
WEB-INF/lib should be more automated.

The sticking point with this particular feature is that while in many
cases it may be appropriate to assume that an exported library in a
project should be included in a web project's WEB-INF/lib, if it depends
on that project, there are valid cases where it should not. Supporting
both cases and maintaining sync when changes are made to dependent
project's exported Libraries will likely make this a non-trivial feature
to implement. I don't know if anything is planned for WTP 2.0 in this
area, so feel free to add your request.

Cheers,
Larry

I fully agree! WTP deployment is completely useless for any reasonably
sized project. You might want to vote for
https://bugs.eclipse.org/bugs/show_bug.cgi?id=138648
perhaps that'll get it fixed...
