Re: Fw: The value for the useBean class attribute com.company.product.thing is invalid.
Hi Kenneth, A while ago I ran into the same problem. I specified a larger heap size like what you did and it helped. I can't think of a way you could control how Tomcat uses memory, but I suppose you should increase your heap size even further. At its worst, you'd just notice that your java process goes into swapping rather than just using the RAM. Have you tried a higher heap-size? Hi, I have an application running on Tomcat 4.1.24 with JapserReport 0.5.0. When I try to print JasperReport with large amount of data, there is a OutofMemoryError there. The tomcat will then shutdown unexpectedly. I search on google and set java -Xms256m -Xmx512m, but it doesn't help. I find it difficult to change to report design to limit the search result. Is there any setting I can control Tomcat's memory usage or restart tomcat programmically when it is shut down? Thanks in advance.

Re: Load Balancing Problem...Urgent
Hi Nicholas, It is great to see undergraduates students (especially from Malaysia), using Tomcat in their projects ;-) High five dude! Ok first of all, if you're building a web application you may want to consider placing Apache 1.3.x in front of your Tomcat instance, to serve a all static contents such as html/images and proxy all tomcat related stuffs to the Tomcat instances. Why not go with the latest:- * apache 1.3.29 * tomcat 4.1.29 * and the mod_jk connector You may find a very good tutorial on how to setup load balanced Tomcat servers at the following URL:- http://www.ubeans.com/tomcat/index.html To answer your question... snip how can I send the request from load balancer connector to the connector in that selected server? After the selected server has finished the process, how can the server send back the response to load balancer and then the load balancer sends back to user? /snip An example of a complete flow of a request to a web application eg: http://www.xxx.com/myapp/start.do is ... User - Apache - Tomcat - Apache - User The way Apache determines if a particular request is to be proxied to Tomcar, is via the JkMount directive in the httpd.conf, see below: JkMount /myapp/* loadbalancer where loadbalancer is a worker of type lb. Please go through the above URL to find out more. Good luck! Nicholas Tham Soon Hing wrote: Hi, I'm an undergraduate student from Malaysia. I'm using Tomcat 4.1.27 to do a load balancing system. This system consists of several tomcat servers and one of them will be the load balancer. When a user accesses a url page, the load balancer will select a server to response to that request. The problem that I faced now is I don't know how to make the selected server to process the request from user browser. As I know the tomcat connector will assign the socket to processor to process it. So how can I send the request from load balancer connector to the connector in that selected server? What should I send (socket? Input stream? Or the request line? How to get these?)?After the selected server has finished the process, how can the server send back the response to load balancer and then the load balancer sends back to user? Can anyone help me on this? Or is there any one has done this before? Can someone show me the sample code for solving this problem? It's urgent. Your help is appreciated.

Re: Tom cat set up problem
Hi Sudhir. You may give 4.1.24 a shot. I used it with jdk1.3.x and it worked fine. Lim is right, javax.xml.* is specific to jdk1.4 and above.

Re: JRun - maybe off topic
Hi Steve, Yes you can. Say you have machine A and B, with A running Apache (w/ mod_jrun) and B with JRun. You have to first configure JRun to disable the JRun web server (in this case you dont want to use it because it's always better to have Apache in front shielding JRun), and then configure the external webserver which will then open up the jcp (JRun connector port). This is the port on machine B that's opened up for mod_jrun on machine A to connect to. On machine A, you need to have the local.properties file of the JRun server running on machine B, so that mod_jrun is able to look up the jcp to connect to. I'm bad at illustrating this with words ... forgive me if the above is kinda misleading. I've done this kinda setup before and it works. I however, just got experience with JRun 3.0, and not 4.0. Good luck! ;-) and happy trying. Steve Harris wrote: So can jrun be split off and run on a sperate box from apache like I can with tomcat ?
