Java.lang.SecurityException using a simple jar file

Question

I created my small application using JDev 11.
Running from JDev it works well.
I created a simple jar file including all my classes and all libraries I used.
Whe I try to run that jar file I get :
java.lang.SecurityException: no manifiest section for signature file entry javax/mail/internet/AsciiOutputStream.classI didn't find any solution.
I worked hardly with JDev 10g but I never had such problem.

Answer 1

I simply created a project containing some classes whish use java mail.
Then I modified the project creating, in the deployment wizard, a "Dependency Analysis" filegroup adding all my classes as well as libraries.
I uncheck the "Include Manifest" chek otherwise I would run into different problems (well documented in the forum).
The jar file is created but when I run the application I get the Security error.
If I remove java mail libraries (activation and java mail)from the list of used libraries and I add it to classpath it works fine.
I suspect the problem could be in Manifes merging.
