It seems with the upgrade to 1.5.0, the execution of the external binary does work, --- but only sometimes?? ---. I can't seem to work out the exact conditions that it works, and seems to be random. Could someone please indicate what I need to add/change in the catalina.policy file to allow the execution of external binaries. I've had a good look at this url and can't seem to find any indicators. > http://tomcat.apache.org/tomcat-5.0-doc/security-manager-howto.html Cheers Mark ------------------------------------- Thanks Enrico, However I seem to have inadvertently solved it. I was updating to the latest release of jre and recompiled the servlet with 1.5.0 and now it works. Previously I was using 1.3.1. So there we go.
