Strategies

This section provides some strategies to use when working with the XML metadata
classes.

Comments

You cannot add comments to XML files using the XML metadata tools. However, the
metadata methods preserve existing comments in the XML files.

Finding metadata classes

The metadata classes that you use to work with the XML files do not use a convention
for naming. So you must find the name-appropriate class to instantiate. To find the
appropriate metadata classes, use the JRun API Javadocs.
The following table describes how common XML elements map to the JRun metadata
objects:
XML file
web.xml
jrun.xml
application.xml
For each subelement of the XML file, you must find the associated metadata object. For
example, for the
