What error are you getting? Does your shell script include a JAVA_HOME variable or another variable of that sort?
Such a variable would have to be set to point to the instance of java that you have installed, assuming you have the correct version required by your application.

without a JRE on the machine, you CANNOT run a .jar file. You'd have to use some sort of tool (ie. Launch4j) to create a native binary. Most of these tools will create a native executable which embeds the JVM (dll, so, etc...) and use C/C++ code to initialize a jvm instance. Once the jvm is initialized, it can run your code.
