Danilo Ghirardelli updated MAGNOLIA-2608:
-----------------------------------------
Attachment: taglibs.patch
Just to refute myself, I attached a patch to do what Philipp suggested. The
attached patch wraps freemarker and tricks it to load jars from all the
classpath when they are requested under WEB-INF/lib.
The counterpart getResourceAsStream has been changed as well to do load files
with absolute paths. This is a potentail security problem, but given that the
method is called only by freemarker class and only with the data provided by
the previous method, there should be no risk of loading random files on
filesystem.
This make possible working with freemarker in Magnolia directly under eclipse,
without deploying.

> freemarker can't load tag libraries when magnolia (magnolia/trunk) is run
> inside eclipse. The magnolia webapp is run from the eclipse workspace,
> without copying resources to a standard webapp layout (WEB-INF/lib doesn't
> exists and taglib modules are not jarred).
> Unfortunately freemarker looks for taglib in a WEB-INF/lib folder explicitly
> and dies with a NPE if the folder is missing:
> Caused by: java.lang.NullPointerException
> at
> freemarker.ext.jsp.TaglibFactory.getLocationsFromLibJars(TaglibFactory.java:290)
> at
> freemarker.ext.jsp.TaglibFactory.getMoreTaglibLocations(TaglibFactory.java:206)
> at freemarker.ext.jsp.TaglibFactory.get(TaglibFactory.java:163)
> .. or simply complains about the missing taglib if an empty WEB-INF/lib
> directory is created:
> freemarker.template.TemplateModelException: Could not find webapp resource
> /cms-taglib
> at freemarker.ext.jsp.TaglibFactory.loadTaglib(TaglibFactory.java:432)
> at freemarker.ext.jsp.TaglibFactory.access$300(TaglibFactory.java:106)
> at freemarker.ext.jsp.TaglibFactory$Taglib.load(TaglibFactory.java:414)
> (tried by simply adding the demo-project dependency to the empty webapp)
> unfortunately really annoying during development...
