java.lang.SecurityException: invalid SHA1 signature file digest for com/microsoft/sqlserver/jdbc/CharacterStreamSetterArgs.class
Mircosoft had signed the jar file thru their own tools. So when you try to use the jar file directly or signing by your own tool and using on your JNLP will give this problem.
To solve this problem steps to be followed.
1. Extract the sqljdbc.jar or sqljdbc4.jar file
2. Goto META-INF Folder
3. Open MANIFEST.MF and delete all the lines other than first line and save it
4. Delete other files which exist in the same folder
5. Finally once again make a new jar file including com and META-INF folder as sqljdbc.jar or sqljdbc4.jar
