Deploying a Java project on Linux system

Question

I developed a project using Java and now I've to deliver it to client who is using Linux. Which executable file format will be delivered and how to make that?

Answer 1

Executable file format?

If you're delivering a Java app, give them a jar file (and associated libs).

Provide a shell script to set up its environment and execute it.

For example, assuming I define ROOT_DIR as my app's install directory, and so on:

CLASSPATH="${ADD_JARS}:${CLASSPATH}:${ROOT_DIR}/lib/myApp.jar:\
${ROOT_DIR}/lib/jibx/jibx-run.jar:\
${ROOT_DIR}/lib/jibx/xpp3.jar:\
${ROOT_DIR}/lib/bindings.jar:\
${ROOT_DIR}/lib/commons-lang-2.0.jar:\
${ROOT_DIR}/lib/forms-1.0.5.jar"
"${JAVACMD}" -Xmx256M -DanyDefsNeeded=foobar -Dbase.dir="${ROOT_DIR}" -cp "${CLASSPATH}" myApp.main.Launcher "$@"

What goes into the shell script depends totally on what your app actually needs to start up.

Answer 2

A jar. If it is not executable, then a script (.sh) to launch the jar.
