Re: IMS headers and procedures

Hi Miguel,

You may want to cvs update ( the class cast may already be fixed). Do 
take a look at the additions to SipHeaderFactoryImpl in support of your 
header classes. You have to add something there too.

In general, these changes look good and they are welcome. I'd be glad to 
take your changes and additions.

Please send me diffs against cvs HEAD (you can use eclipse to generate 
diffs).  You  have some new files to add. Please send them to me for 
inclusion.

Please also contribute test cases for you new headers. I've been a bit 
lose about this in the past and have always paid the price for being lose.
Please make good javadoc for your additions so others may use your work. 
No javadoc errors please!

The parser tests are located in tests/unit/gov/nist/sip/parser

Please add test cases for your new headers.
The structure of the tests should be quite obvious.

Thanks on behalf of the user community.


Regards

Ranga
