not able to change java.io.tmpdir

Question

I am trying to change the java.io.tmpdir directory using this command

java -Djava.io.tmpdir=/temporary

But this doesnot succeed and displays the 'Usage' of the java command. I am doing this in a RHEL machine.

Thanks in advance

I have deployed an application on WebLogiv which uses axis2 version 1.5. I find that axis2 1.5 using java.io.tmpdir to store its temp files. I want the location where these temp files are stored. Where in the weblogic do I specify the java.io.tmpdir value

You need to use that command as part of running a program, not just java -Dkey=value.

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

where com.foo.Bar is the class which contains the main method.

Alternatively, you can do this programmatically.

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

This `System.setProperty("java.io.tmpdir", "/temporary");` is the best way i think. – Talha Asghar Dec 18 '21 at 12:34
Setting the java.io.tmpdir from the command line doesn't work, it gets reset to the default of /tmp – Juan Jimenez Jun 06 '23 at 16:34

Take a look at this answer https://stackoverflow.com/a/1924159/594793

Specifically, this part:

A different value may be given to this system property when the Java virtual machine is invoked, but programmatic changes to this property are not guaranteed to have any effect upon the the temporary directory used by this method.
