My program, that uses the Java MSN Messenger library, is in error

I want to develop a program using the Java MSN Messenger library (JML). I can not solve a problem where the following exeception is thrown.

ERROR/AndroidRuntime(312): FATAL EXCEPTION: Thread-21

**ERROR/AndroidRuntime(312):     java.lang.ExceptionInInitializerError

ERROR/AndroidRuntime(312):

How to fix it?

You are trying to use Java MSN Messenger library. This library was created for J2SE/J2EE and can not be used on Android.

As you can see net.sf.jml.util.StringUtils is referencing sun.security.action.GetPropertyAction which is not available on Android.

I find a solution, i hope this can help to someone.

You must to recompile jml with a little change in net.sf.jml.util.StringUtils.java

1º Download the code of jml here:

   http://sourceforge.net/projects/java-jml/files/java-jml/jml-1.0b4/

2º And then apply this patch

 http://sourceforge.net/tracker/?func=detail&aid=2910514&group_id=118829&atid=682291

(i recomend download the code with a svn program and then aply the patch with tolstoi or other svn program )

When you have the code parched, create a .jar (right click in the project / export ) and then add this .jar to your msn project.
