If you're nervous about registry work, back up your registry. Then open regedit and find: HKLM\SYSTEM\CurrentControlSet\Services\Apache Tomcat 4.1\Parameters
(You can choose a different control set as well, and for Tomcat 5 users, this is under ...\Services\Tomcat5\Parameters.) You should see some Java startup options there already. They are named "JVM Option Number x" where x is a zero-based option count. The x *must* be incremented by one each time. If you skip a number, only the options before the skip will be loaded. e.g. If you set options 0, 1, 3, 4, and 5, then only 0 and 1 will be loaded. The rest will be ignored. Also, you must set the "JVM Option Count" key to the total number of options you have set. This will be one more than your highest option number. Think of it as an array where the options are the elements and the option count is the array length. I would guess that's how it's implemented. -----Original Message----- From: "David Johnson"<[EMAIL PROTECTED]> To: "Tomcat Users List"<[email protected]> Date: Thu Jan 06 07:40:27 PST 2005 Subject: Re: Out of Memory when compiling JSP (Struts app on Tomcat 4.1.27) >Cool.
