    Default how to configure Launch4j the jre bundle and find my JRE version etc?

    Hi,

    I've tried to used this Launch4j to test out my mini Java SE programs.

    However, I'm stuck at the JRE bundle.

    What happened was that I've entered all the necessary action required by Launch4j.

    But, there's this part where I'm asked to enter the JRE version.

    So, what I did is look at my Netbean version which is 6.8.0 and entered that as the version. I can sense something is wrong here right? So, can someone advise me where to find my JRE version?

    Now, after clicking on my desktop exe file created by Launch4j, I can't click and run the file at all. It will bring me to the browser to download the JRE and latest Java to download.

    So, I hope someone can help me resolve this problem. How can I make it run after clicking on the desktop icon and the exe file.

    Thanks.

    Go to the command line of your OS and ask it for the current JRE version: java -version
    Alternatively, ask your JDK for the its version: javac -version

    Got it. But, after entering the version and making the exe file, the file won't run at all cos it says my jar is corrupted! However, it works perfectly in NetBean IDE. Any idea how to make it work. I run a couple of times and yet run into the same problem.

    Break the step down to see where failure occurs - make sure all steps upstream of launch4j are working. For instance, compile the code and package into an runnable jar - does this jar run from the command line as a stand-alone? If no, you know your jar is not packaged correctly. If yes, then something may be wrong with the launch4j configuration - inspect all configs (been a while since I used launch4j, so you might seek a forum specific for that app).
