why jre after exe produced

i have developed one console application by using jdk 1.5 in one machine 'A' of windows xp as O.S.

after that i produced the jar file. then with the help of a tool

called JExe Creator i produced a exe file . All the above process was done

in machine A. After that i copied that exe file and pasted in another

machine 'B' of windows xp as O.S . That machine 'B' does not contain jre 1.5. i was unable to run the EXE file. after installing the jre 1.5 only, That Exe file runned.

my question is why we need JRE after EXE file is produced.

then with the help of a tool called JExe Creator i produced a exe file .

Maybe you should look into JExe Creator to see exactly what is done by the tool. Maybe this tool doesn't generate a "pure" executable, and needs a JRE to run.

JExeCreator is NOT a native compiler, it is a native LAUNCHER. It wraps the jars into the executable and also creates a launch-command but it does NOT compile your Java classes to native.
