Embed (internalize) java in your desktop application

Question

I am trying to embed (internalize) java into the installation directory of my application. Looking at the documentation and all other help available that I could go through I copied the java directory to the application one and then set all the environment variables and paths as prescribed. However, when I launch the application using this new java directory it gives java not found error. Can someone give me some tips?

Thanks in Advance!

Answer 1

I wish you good luck in this task but may I ask you why do you want to do this? If you really wish to put java under your application install java there. You can use silent mode of installation. I do not remember the syntax right now but if you are on windows, java is installed by Windows installer, so search for "run windows installer silently" and follow the instructions. I believe that this approach will work on better and easier.

You've obviously not set up the %PATH% environment correctly. That's what is causing whatever is launching Java to say "java not found".

You could:

• modify whatever is trying launching Java to print out the environment variables, or
• change whatever is trying launching Java to use the absolute pathname for the "java" command.

将源下载到WinRun4J（在Windows上是javaw的替代），并查看它们如何初始化JVM。
