Subject RE: Tomcat 4.1.30 (although its still there in tomcat 5.0.28) temp file issue.
Date Tue, 14 Sep 2004 18:51:08 GMT

Hi,
Ant 1.6 adds a tempdir attribute to the Javac task.  You can use that to
se the tempdir via Ant or in the DefaultCompilerAdapter.  You will need
to run with Ant 1.6 or later obviously, and also have a custom version
of DefaultCompilerAdapter.  If you'd like your enhancement to be ported
into the main tomcat code, please submit an enhancement issue to
Bugzilla with the .diff that includes the new compiler option.
