You should do the following:
1. Create a folder in your project directory(for example: toerase)
2. write this line over: dist.dir=dist
with this: dist.dir=toerase
in project.properties

It should works!

You’ll have your new folder and the unsigned jar inside, but i think it’s not a problem.

if i not using
jarsign.signedjar=dist/TestApplet.jar
it works, it creates signed TestApplet.jar
But it should created at dist/TestApplet.jar in order to run properly

Sounds like you put the text in the wrong place in your build.xml – is it inside your tag?

The following error occurred while executing this line:
C:\Documents and Settings\work\My Documents\NetBeansProjects\helloApplet\build.xml:75: Unexpected text “target name=”-post-jar”>”
BUILD FAILED (total time: 0 seconds)
Can u explain this?

Is that the full error message? If there’s nothing after the ‘for:’ part it probably means that you’re not passing the alias name at all.

Make sure that you have set jarsign.alias correctly in your project.properties file, and that there is an argument for jarsign.alias in your build.xml file.

If it’s still not working, go back to basics. Try manually signing your .jar file from the command line using your keystore. If that’s not working, you’ll know it’s a problem with your keystore, and Google should be able to help you from with that.

This tutorial is more about how to use the keystore automatically in NetBeans, and it’s assumed that you already have a bit of knowledge about the process.

If you need help in actually creating the keystore, try running through this tutorial first: http://www.cs.princeton.edu/introcs/85application/jar/sign.html

No, that is not possible. If you password protected (encrypted) your .jar file, the Java runtime environment would not be able to understand the contents in order to run it.
