Pls help me on config of the memory problem
Hi, How to set the maximum number of threads or clients that the server can deal with simultonously? Running java bean takes much memory, so I want to control the number of users who can run it at the same time. I use Apache2, Tomcat4.1 and mod-Jk2 under win2k. Thx, Minger __ Do you Yahoo!? Yahoo!

Re: JSP's in other directories
You use JK2 as the connector between Apache and Tomcat? If so, you can map your jsp in the workers2.properties.

To forward to one of my JSPs from a servlet, I use the following line of code: String TARGET_JSP = /main.jsp; javax.servlet.ServletContext sc = this.getServletContext(); javax.servlet.RequestDispatcher rd = sc.getRequestDispatcher(TARGET_JSP); rd.forward(); That's one way to do it, even though the servlet is in /MyApp/WEB-INF/classes and the JSP is in /MyApp. Erik - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] __ Do you Yahoo!?

How to configure number of sessions, threads or connections of the server?
Hi, I met a problem on my server's configuration. On my website, the user can simulate the manufacturing systme (java bean) online. If I run the simulation offline (with the JBuilder), it's no problem to run for the real time from year 1990 to now. When I put it online, it can only run for short time (from 1/1/2002 to now), and I got some error for the long running time simulation. So I think it the memory problem. Therefor, I want to set the number of threads or connections the server can server simultanously. But I tried and failed. If you know something on it or you think it's not the memory problem, please help me. I use Apache2 and Tomcat4.1 (as the service to deal with jsp files) under windows2000; In fact I once only used Tomcat and the same problem. You can test it: 1.http://shan.bu.edu/CRCD to sign in with zcm as username and password; 2.click first button reset simulation to set the beginning time of simulation; 3.click the last button start simulation to run simulation.

Hi, John Is there any HOWTO for win2k? Similar to that for RH? For my setup and configure of Apache, Tomcat and JK2 on win2k, it seems that Apache and Tomcat can work well seperately. But it cannot work to open jsp file with Apache to acivate Tomcat to deal with. And I got the message on the Tomcat window: APR not loaded, disabling jni component:java.io.ioexception: no jkjni in java.library.path. Can you help me? Thanks lots, Minger --- Turner, John [EMAIL PROTECTED] wrote: I don't think you can get any simpler than this: http://www.johnturner.com/howto The version numbers are irrelevant...the procedures are the same. Newer versions of Tomcat use one connector class to handle multiple protocols. That class is called CoyoteConnector and it talks JK, JK2, and HTTP (and I think HTTPS as well). Older versions of Tomcat used a class called Ajp13Connector to talk JK. If you are using JK, you can use either CoyoteConnector (enabled by default) or Ajp13Connector. If you are using JK2, you have to use CoyoteConnector. In your files, you are using JK commands (JkMount) with a JK2 module, that won't work. Check my HOWTO, if you have problems, post back to the list. Also, flagging messages as urgent or high importance isn't very polite, and will probably cause more people to ignore your post than to read it and answer itwe're all very, very busy, and your important issue isn't any more important than those of anyone else.
