Running java with JAVA OPTS env variable has no effect

Question

In a shell script  I have set the JAVA OPTS environment variable  to enable remote debugging and increase memory   and then I execute the jar file as follows   export JAVA OPTS  -Xdebug -Xrunjdwp transport dt socket address 8001 server y suspend n -Xms512m -Xmx512m  java -jar analyse jar      But it seems there is no effect of the JAVA OPTS env variable as I cannot connect to remote-debugging and I see no change in memory for the JVM   What could be the problem   PS  I cannot use those settings in the java -jar analyse jar    command because I process command line arguments in the application

You can setup  JAVA OPTIONS instead of JAVA OPTS  This should work without   JAVA OPTIONS

I don t know of any JVM that actually checks the JAVA OPTS environment variable   Usually this is used in scripts which launch the JVM and they usually just add it to the java command-line   The key thing to understand here is that arguments to java that come before the -jar analyse jar bit will only affect the JVM and won t be passed along to your program   So  modifying the java line in your script to   java  JAVA OPTS -jar analyse jar      Should  just work
