Re: ibator question about <commentGenerator> element

by Jeff Butler-2 :: Rate this Message:

This is a limitation in the eclipse plugin - the classpath for the "Generate iBATIS Artifacts" menu option is hardcoded in the plugin.xml file. You have these options:

1. Add your class to the JAR as you are doing

2. Package your class as a seperate plugin and add it to the Abator UI plugin.xml dependancies

3. Use the integrated Ant task rather than the menu option - because you can set the class path with the Eclipse Ant support

#3 is the best option now. When I finally get to releasing ibator, I plan on doing away with the menu option completely and using a launch configuration instead (Run As->Ibator Build). This will give you better control over the classpath for situations like these.

BTW - I'm in the midst of a major refactoring of ibator now. This is the cause of the delay in releasing.

Hello:

I have created a specialization of the DefaultCommentGenerator class and over-ridden the addFieldComment method.

Using Eclipse, I "Generate iBATIS Artifacts" and everything works fine as long as I add my class file to the abator.jar file in ./eclipse/plugins/org.apache.ibatis.abator.core_1.1.0.

When I change the plugin.xml file in ./eclipse/plugins/org.apache.ibatis.abator.core_1.1.0 to include an additional <library> element to refer to my class file, I get the following run-time error (in the Eclipse PDE Runtime Error Log).
