I have installed NSIS plugin in My eclipse on windows platform.
I have java class Calculator.java

I need help in communication with nsis file to java. Is it possiable in nsis?. If its possible please give me the steps.

can any one help this concept?

Answer 1

You execute a Java JAR in NSIS with the ExecWait command.

ExecWait 'javaw.exe -jar \
            ${networkDir}\your.jar \
            parameters'

You can check the error flag if and only if your Java JAR returns a condition code:

System.exit(0);   // Good return
System.exit(8);   // Error return

As far as I know, you cannot reference Java methods in NSIS. Your Java JAR must have a main method.

Your Java JAR can write a file which can be read later by NSIS.
