Unable to change Java io. tmpdir

I'm trying to change Java. Net using this command io. TMPDIR directory

java -Djava.io.tmpdir=/temporary

This is not successful and shows the "usage" of Java commands I do this on RHEL machines

Thank you in advance

I deployed an application using axis 2 version 1.5 on weblogiv I found that Axis2 1.5 uses Java io. TMPDIR to store its temporary files Where I want to store these temporary files I specified Java. Net in Weblogic io. TMPDIR value

Solution

You need to use this command as part of the running program, not just Java - dkey = value

java -Djava.io.tmpdir=/temporary com.foo.Bar

Including com foo. Bar is a class that contains the main method

Alternatively, you can do this programmatically

System.setProperty("java.io.tmpdir","/temporary");
