JAIN-SIP 1.2 Reference Implementation
NOTE: This is the official jain-sip 1.2 Reference Implementation. 

See docs/index.html

You need to install J2SE JDK 1.5 or above. You can
get the J2SE SDK from


1. You need to install ant and the junit extension for ant on your machine. 
2. You need to have junit.jar in your classpath to run the tck.
3. You need to have log4j.jar in your classpath (included in this distribution). 

There are versions of the dependent libraries in the lib directory.  
For your build environment, please edit

YOU DO NOT need jdom.jar and ant.jar. These are strictly for buildng 
the ant tools.

Building It from Scratch
The distribution is pre-built but should you feel inclined to make changes,
or run the examples, you may wish to rebuild everything.

ant make 

Builds everything.

Building the TCK

Edit and set the claspath to your implementation.

ant runtck 

(builds a jar file containing the TCK and runs it).

Look in test-reports  to see the results of your run.


IMS Headers, headers in gov.nist.javax.sip.extension and all the classes
that are suffixed with "Ext" in their name can be used without concern as
they will be included in the next generation of the API. These will not 
change as a rule.

You should refrain from using any other internal classes. These are subject
to change without notice.

Running the examples

Please ensure that the directory  classes  (relative to where you have
built the distribution) is included in the  classpath. Ant targets
are provided in each example directory to run the examples.
