Answer 1

You can launch a child process and get its process exit code with ExecWait .

If you need to return more data than a single number you need to store the data in a file or in the registry and then read it back using normal NSIS instructions....

Answer 2

From the NSIS srcipt, you can run Exec or ExecWait to run the "java" and pass the PropertiesReader.class as parameter to it. Your java program can write the property_value to a file which you can read back from the script.

Here is a link that has a heading "NSIS and Java". You can check that out. Just make sure that the PropertiesReader.class file is in the classpath.
