My RCP app shows the Error Log view, but renames it to "Messages" so as
not to frighten users. This is done via the following extension in
plugin.xml:
<extension
point="org.eclipse.ui.views">
<view
name="%views.messages.name"
icon="icons/obj16/info.gif"
category="org.eclipse.pde.runtime"
class="org.eclipse.pde.internal.runtime.logview.LogView"
id="org.eclipse.pde.runtime.LogView">
</view>
</extension>
This works fine when launching the app from a workbench. But when
packaged for export and run externally, the Error Log view is not loaded.
The plugin containing the LogView class,
org.eclipse.pde.runtime_3.2.0.v20060329-1600.jar, is packaged with the
RCP app. Yet when the app runs the part is not displayed; instead you
get an error "Unable to create view: Plug-in
com.rolemodellers.rim.humanedj was unable to load class
org.eclipse.pde.internal.runtime.logview.LogView.", with the class
loader failure stack shown below.
I have tried editing MANIFEST.MF in the pde runtime plugin jar, removing
the x-friends qualifier on the package in question; i.e., changing this:
Export-Package: org.eclipse.pde.internal.runtime;x-internal:=true,org.
eclipse.pde.internal.runtime.logview;x-friends:="org.eclipse.pde.ui ",
org.eclipse.pde.internal.runtime.registry;x-internal:=true
to this:
Export-Package: org.eclipse.pde.internal.runtime,org.
eclipse.pde.internal.runtime.logview,
org.eclipse.pde.internal.runtime.registry
but it doesn't make any difference.
Any ideas, anyone?
Thanks!
All the best
Keith

Got it working, but no idea why. All I did was deploy the Application
plugin unpacked (i.e., as a directory rather than a jar). Now the Error
Log view loads fine, even without modification to the manifest in
org.eclipse.pde.runtime.
?!
