Exception because of emty line in Manifest.mf

[pascal1]

Hello,
the ActivitiDesigner throws an exception when the Manifest.mf of the Jar-File contains an emty line. In my Jar, created by a build.xml, there are two emty lines at the end of the Manifest.mf and because of this it doesn´t work. When I remove them manually it works well…

Maybe you can implement that emty lines will be ignored…

Thanks,
Pascal

I think we use the default manifest-reading capabilities… Can't you make your ant-build file create a manifest that doesn't contain the empty lines?

Can you show the stack trace thrown by the designer? So I can assert this is activiti-specific reading or not?

[pascal1]

Yes, I´m looking for the reason of this emty lines, but I didn´t find anything yet. It is only a standard "<manifest>"-tag where attributes are added in my build.xml

Looks like error is in loading an Image to display in SWT. If you claim the removal of the blank lines fixes this problem, probably the activiti-extention-name that is read from the manifest (with the empty lines) causes a certain resource not to be found…

[pascal1]

Yes, the last line in the Manifest.mf is the activiti-extention-name, so maybe with the empty lines an additional ressource wants to be found… I´m searching for a way to get a right Manifest.mf out of my ANT-Build…

Now I have the same Exception at another point in my Custom-Shape. The MoneyTask-Example works, my own one never works. Because of that I changed the example to a class with my properties. That still works. But when I want to rename the Class or the package-Path, suddenly there is that Exception again. What can I do to get my own Package-Path and Class-Name for the custom shape in the palette? Is there any config or something like that where I have to change something?

Thanks,
Pascal

[pascal1]

So, after some more attempts now I have:

- Eclipse Indigo with Activiti-Designer 5.9 : Like the post before (own Jar doesn´t work, the example works, example with renamed class doesn´t work)

- Eclipse Helios with Activiti-Designer 5.8.1: My own Jar works perfect

- The installation of Activiti-Designer 5.8.1 on Eclipse Indigo fails:
     "Cannot complete the install because one or more required items could not be found.
     Software being installed: Activiti Eclipse BPMN 2.0 Designer 5.8.1 (org.activiti.designer.feature.feature.group 5.8.1)
     Missing requirement: Activiti Designer - Eclipse 5.8.1 (org.activiti.designer.eclipse 5.8.1) requires 'bundle org.eclipse.emf.transaction 0.0.0' but it could not be found
     Cannot satisfy dependency:
       From: Activiti Eclipse BPMN 2.0 Designer 5.8.1 (org.activiti.designer.feature.feature.group 5.8.1)
       To: org.activiti.designer.eclipse [5.8.1]"

…and after that I get an Exception when I want to open a Diagram…


Maybe there must be changes between 5.8 & 5.9 that are the reason for my problem?
