I call php script from extensions.conf like this

Now I am planning to replace this php file from java
Is it possible to call jar file from extensions.conf like above ?

Can you call it from the shell level? I don’t think that JAR files support Unix #! header lines, although they are ZIP files and ZIP file directories are at the end of the file, it may well be possible to construct one that matches that convention. It is probably easier to use a script in another language to start Java, probably a shell script.
