[webstart] NPE when signing dependencies
----------------------------------------

         Key: MOJO-295
         URL: http://jira.codehaus.org/browse/MOJO-295
     Project: Mojo
        Type: Bug

  Components: sandbox  
 Environment: WinXP
Maven 2.0.2
Latest maven-jar-plugin from SVN
Latest webstart checkout
    Reporter: Michael Böckling
    Priority: Critical


In JarSignMojo, the call to this.signedjar.getPath() produces a NPE, because in 
JnlpMojo:863, signJar.setSignedJar() has been commented out.

Stacktrace:

[debug] jarsigner executable=[C:\Programme\Java\jdk1.5.0_06\jre\..\bin\jarsigner
.exe]
