no. It does not mean that. you can set fork option to false, and reloadable/developement to true or vice versa, anyway you like. But I still recomend that in production environment you set developement to false and reloadable to false.
setting fork option to true will throw avay the javac process when it's done it's work, leaving no memory leaks, but I think it's a little bit slower than fork=false. I'm not sure, maybe someone else can answer that.
And also I have noticed for each session,for the first time it takes lot of time to load theJSP page and hence forth the loading of those pages is quick. Does it mean JSP pages compile
first time and not afterwards for that session?
Page compilation is only done once for each jsp document. I think your session lagging has to do with something else, some session related code/rendering etc.

Hi, Good advice. The fork option for jasper exists in tomcat 5, it's key to helping with these sorts of problems.

hi,
I think I am correct when I say javac is only used by tomcat compile jsp. You should be able to eliminate javac calls by pre-compiling your jsp pages.
Now, as I have not yet started using tc v.5.x I am not sure if this will help, but in 4.1.x there is a switch in /tomcat/conf/web.xml to set the jsp compiler engine to forc the process. I recomend that you check that one out.
In my opinion, if you are using tomcat in production environment you should turn of any "reloading-options" as they will always collect memory. that means context reloading, auto-deployment, jsp reloading and developement switches.
By doing that you will minimize the overhead (both process and memory) of tomcat, leaving only the basic footprint of tomcat with the current configuration.
Hope it helps -reynir

Hi All,
I have seen in Tomcat 5.0.25 Release notes the JAVAC Leaking memory
problem is mentioned. Earlier I was using Tomcat 3.3.1 and was getting java.lang.OutOfMemory Exceptions after every 2-3 days and had to restart my Tomcat Server.I am planning to migrate to Tomcat 5.0.25 version , but here too seems is the same problem .I am using jdk 1.3.1 version. If I use jdk 1.4 version,would this problem be resolved? Or is there any way to get around this problem ..?
Any feedback is welcome...
Thanks in Advance,
