Strange PlugIn starting problem [message #37022]

Hi,

I have written a plugin called "myplugin". I tested it with the
runtime-workbench and all was well. Now, I thought that "myplugin" was
probably not the best name, so I changed it to "de.uni_sb.cs.dd" (which is
only hardly better but at least fully qualified :)). However, after I
(manually) changed all package names (from "myplugin.x" to
"de.uni_sb.cs.dd.x") and altered the imports, the plugin does not run
anymore! I must add that I also had problems with the classpath, so I
created a completely new project and added each file separately to its new
destination (i.e. de/uni_sb/cs/dd/x). I copied the manifest file and
replaced all "myplugin" strings, and then I selected "Update classpath.."
from the context menu of the manifest file and rebuilt the whole project.
Now, when I select an action of my plugin, I get the error message that
"The chosen operation is not currently available." along with the
exception: "Could not create action delegate for id:
de.uni_sb.cs.dd.actions.IsolateAction
Reason:
Plug-in de.uni_sb.cs.dd was unable to load class
de.uni_sb.cs.dd.actions.IsolateAction."

Now, the class de/uni_sb/cs/dd/actions/IsolateAction exists, and it does
implement "IWorkbenchWindowActionDelegate".

Does anybody have an idea what I could have overlooked?
The plugin worked before I renamed it... (Next time I will think of an
appropriate name _before_ starting to program :-)).

Well, thanks for your help,
Philipp

Check the package names in your plugin.xml

Hi,

thanks for the advice, but I already replaced all occurences of
\"myplugin\" with the correct name in the manifest file. The error still
occurs. In fact, I searched for \"myplugin\" in all files and did not get
a result, so I am pretty confident that I have replaced all occurences.

Verify that the requires section in your plugin.xml is correct. Maybe
one of the required plug-ins got removed while playing with the Java
build path.

Hmm, the requires section looks okay to me.
Maybe I am just too blind for it right now. Here is my plugin.xml file
(slightly shortened). Notice that I renamed the project again (thinking
that maybe the underscore could lead to problems). The new name is
"de.uds.cs.st.dd", so the IsolateAction is in
de/uds/cs/st/dd/eclipse/actions/IsolateAction.java and
de/uds/cs/st/dd/eclipse/actions/IsolateAction.class

This is really driving me crazy -- I hope that it's just an easy
"oooups"-error in the end :)

The following library entries are not needed since you already reference
the plug-ins in the required section:

<library name="org.eclipse.core.boot/boot.jar"/>
<library name="org.eclipse.core.resources/resources.jar"/>
<library name="org.eclipse.core.runtime/runtime.jar"/>
<library name="org.eclipse.ui/ui.jar"/>
<library name="org.eclipse.jdt.core/jdtcore.jar"/>
<library name="org.eclipse.jdt.launching/launching.jar"/>
<library name="org.eclipse.jdt.ui/jdt.jar"/>
<library name="org.eclipse.jdt.debug/jdimodel.jar"/>
<library name="org.eclipse.jdt.debug.ui/jdiui.jar"/>
<library name="org.eclipse.debug.core/dtcore.jar"/>
<library name="org.eclipse.debug.ui/dtui.jar"/>
<library name="org.junit"/>

Hi,

after all the error was quite stupid:
I had the runtime-workbench start with the "-dev /bin" parameter, whereas
this should now read "-dev /", since there is no more bin directory...
Well...

Daniel: Thanks for mentioning the duplicates in my "runtime" section. I
removed them now...

Thanks for the help,
Philipp
