How do we run Java with /tmp noexec ?

[mydomain]

Hi wonder if someone would be kind enough to advise how our clients can run java from shell or crontab when we have /tmp and /var/tmp etc set with noexec for security reasons.

Currently when trying to run it gives:

/usr/bin/java: line 67: /var/tmp/javagM2660: Permission denied
/usr/bin/java: line 67: /var/tmp/javagM2660: Success

and does not run due to the permissions issue.

Any help is greatly appreciate, TIA.

In the java programming environment, it is likely that the system environment variable java.io.tmpdir is set to
/var/tmp/ <SomeSessionvariable>

(or some other environment variable)

since there is a "line number" (line 67) listed, perhaps the java command is actually a shell script.

a) Verify if /usr/bin/java is a shell script, and post the entry around those lines

or

b) See if your java environment variable java.io.tmpdir can be configured to use something like
$HOME/tmp (where each user has a tmp subdirectory and execute access is allowed)

The java shell script /usr/bin/java around line 67 shows:

export CLASSPATH="$clp"
COMMAND=`mktemp /tmp/javaXXXXXX`
echo "rm $COMMAND" >$COMMAND
echo "exec /usr/bin/gij $params" >>$COMMAND
chmod +x $COMMAND
exec $COMMAND

How can this be changed exactly so each user can run java and it uses their own $HOME/temp directory?


Thanks in advance.
