[news.eclipse.platform.rcp] Classpath Problems working with Libs that us

[Benjamin Pasero <bpasero@xxxxxxxxxx>]

Hi,

my idea was to work with JDom and allow to contribute the used
XML Parser.

Currently my setup is:

- Apache Xerces XML Parser as contributed library plugin
- JDom as library plugin

and a third plugin in which an instance of SAXParser (JDom) is
created with "org.apache.xerces.parsers.SAXParser" as SAX-Parser-Class.

The JDom library plugin is always present, while the XML Parser
plugin can be replaced by another XML Parser contribution.

The problem is, that JDom inside its SAXParser uses reflection to
instantiate that "org.apache.xerces.parsers.SAXParser". That results
in a NoClassFoundException, as the JDom plugin is not having any
dependancy to the Xerces plugin. Actually it should not have, because
the used Parser is contributable.

Everything works just fine as soon as Jdom is made dependant on the
contribution, but hopefully there is a different way?

Any ideas?

Ben
