Debugging an Oxygen SDK Extension Using the Eclipse Workbench

To debug problems in an extension code without having to bundle its Java classes in a JAR library, perform the following steps:
  1. Download and install Oxygen XML Author.
  2. Create an Eclipse Java Project (for example, MySDKProject) with the corresponding Java sources (for example, a custom implementation of the ro.sync.ecss.extensions.api.StylesFilter interface).
  3. In the Project build path add external JAR references to all the JAR libraries in the [OXYGEN_INSTALL_DIR]/lib folder. Now your Project should compile successfully.
  4. Start the standalone version of Oxygen XML Author from the [OXYGEN_INSTALL_DIR] and in the Document Type Association preferences page, edit the document type (for example, DITA) to open the Document Type configuration dialog box. In the Classpath tab, add a reference to your Project's classes directory and in the Extensions tab, select your custom StylesFilter extension as a value for the CSS styles filter property. Close the application to save your changes.
  5. Create a new Java Application configuration for debugging. The Main Class should be ro.sync.exml.Oxygen. The given VM Arguments should be:

    -Dcom.oxygenxml.app.descriptor=ro.sync.exml.EditorFrameDescriptor -Xmx1024m -XX:MaxPermSize=384m
