[news.eclipse.tools] Re: Editor plugin: instantiation external class

["Bob Foster" <bob@xxxxxxxxxx>]

Built path and plugin loading are unrelated. You need to include the jar in
your plugin folder (or it needs to be in another plugin) and add a runtime
library element to your plugin.xml.

Unless it's xerces; then you need to not put it in your plugin folder and in
your plugin.xml import the org.apache.xerces plugin. You will then need to
call the thread's setContextClassLoader(this.getClass().getClassLoader())
before trying to call parser stuff.

Oh, yes, and bow three times in the direction of an OTI office, any one will
do, while reciting, "It makes perfect sense. It makes perfect sense. It
makes perfect sense." ;-}
