Here is a checklist that will help in making a contribution easy for both the contributor and the core developers that have to review the contribution.

• Checkout Webdav trunk code:
• svn co https://webdav-servlet.svn.sourceforge.net/svnroot/webdav-servlet webdav-servlet
• Send a message to the Webdav Servlet mailing list, or file a bug report in Jira to describe your proposed changes and check that they fit in with what others are doing
• Make the code change
• Add APL 2 License headers, note all your work will be contributed as Apache License 2.
• All public classes and methods should have informative  Javadoc comments
• Do not use @author tags
• Contributions should pass existing unit tests
• New unit tests should be provided to demonstrate bugs, fixes and new functionality
• Run the build including the tests and ensure that you can build a distribution.
• Create a patch
• Make sure you code is added to svn e.g. svn add src/.../NewClass.java
• Create a patch file svn diff > webdav-servlet-1234.patch
• where 1234 is the Jira issue number
• Inspect your patch file and check that :
• You did not reformat code
• Unused code is removed
• You have commented code whose function or rationale is not obvious
• Updated documentation
• Test your patch file patch -p0 < my-patch.patch
• Attach your patch file to a Jira issue
