I usually use a bat script for that  Here s what I typically use    echo off set d   dp0 java -Xmx400m -cp   d myapp jar  d libs mylib jar  my main Class      The   dp0 extract the directory where the  bat is located  This allows the bat to find the locations of the jars without requiring any special environment variables nor the setting of the PATH variable   EDIT  Added quotes to the classpath  Otherwise  as Joey said   fun things can happen with spaces

We have found Jsmooth to be well-working and easily scriptable with ant under Linux   You may want to use one-jar  also easily scriptable with ant under Linux  to collect a multifile application in a single jar first   We primarily needed the easy deployment of the EXE combined with the  hey  you need Java version X  go here to download  facilities    but what you most likely need is the  Runnable jar     Executable jar  facility in standard Java

I would use GCJ  GNU Compiler for Java  in your situation  It s an AOT  ahead of time  compiler for Java  much like GCC is for C  Instead of interpreting code  or generating intermediate java code to be run at a later time by the Java VM  it generates machine code   GCJ is available on almost any Linux system through its respective package manager  if available   After installation  the GCJ compiler should be added to the path so that it can be invoked through the terminal  If you re using Windows  you can download and install GCJ through Cygwin or MinGW   I would strongly recommend  however  that you rewrite your source for another language that is meant to be compiled  such as C    Java is meant to be a portable  interpreted language  Compiling it to machine code is completely against what the language was developed for
