2 Java Launcher Example Files Question
Hello everyone,
I am entirely new to NSIS. I downloaded it two days ago. I researched the docs offline. Today I registered for this forum. I was really looking for a way to create a java launcher. So, this is my first post.
I found two java example files, I used the one that deals with the javaw.exe at nsis.sourceforge.net/A_slightly_better_Java_Launcher, and the other one that used the java.exe nsis.sourceforge.net/Java_Launcher, but I was unsuccessful compiling the first example {that deals with javaw.exe}.
I then used the one that deals with java.exe example which worked, and I edited it, replacing java.exe with javaw.exe in every instance I found. [I hope I am making this point very clear.]
Here is the file that has been edited:

Although I can successfully create a launcher with that modified code, an error message window would report: "Could not find the main class. Program will exit"
By the way, I am dealig with an executable jar file found at java-forum.org/de/userfiles/user3690/HyperLink.jar on Sun's website. Needless to say, it is a single jar file.
I suspect, that the errors occur between lines 13 to 21 that code above. The main class is "Demo.class"
The sample executed jar file GUI can be seen with the screen shot attached. The same should also be the case when executing the launcher.
I would appreciate any help from anyone concerned.
