Re: [cdt-dev] Template engine can't see my pagesAfterTemplateSelectionPr

[bala.torati@xxxxxxxxxxx]

Hi Beth,

I have attached a fix for this problem,
not using the reflection API directly. Originally it was implemented in
the "Eclipse way" to create the executable class using ExtensionRegistry,
when I implemented it as a standalone plugin. But during the integration
of TE into new project model, and the seperation of core and ui parts of
the TE resulted in calling the Reflection API directly. I fixed this problem
now with the following patch. Did you open a defect for this issue? If
not, please ask a committer to apply this patch, if you found it's ok.



Regards,
-Bala

Subject	[cdt-dev] Template engine can't see my        pagesAfterTemplateSelectionProvide class

I'm getting a ClassNotFoundException when the template engine tries to
load
my  pagesAfterTemplateSelectionProvider class.
The class is indeed there.

java.lang.ClassNotFoundException:
org.eclipse.ptp.pldt.wizards.wizardPages.MPIPageProvider
      ....
      at org.eclipse.cdt.ui.templateengine.Template.getExtraCreatedPages(
Template.java:147)

 <template
            filterPattern=" "
            id="org.eclipse.ptp.pldt.projects.MPIhelloWorldCProject"
            location="templates/MPIhelloWorldCproject/template.xml"
            pagesAfterTemplateSelectionProvider=
"org.eclipse.ptp.pldt.wizards.wizardPages.MPIPageProvider"
            projectType=."org.eclipse.cdt.build.core.buildArtefactType.exe"
>
      </template>

in Template.java it's using Class.forName instead of the eclipse class
loader

//e.g.
pagesProvider="org.eclipse.ptp.pldt.wizards.wizardPages.MPIPageProvider";
Class clazz = Class.forName(pagesProvider);
instead of something like.
                    
                     
                     
           
 ExtensionRegistry.createExecutableExtension()        
                     
                    
                     
                     
           



Have you been able to get this to work using a class in another project
from template engine, as the pagesAfterTemplateSelectionProvider class?

Are these changes what you were talking about that will be coming in 4.0.2?
