Re: JK2+Apache2: LogFactory java Error: NoClassDefFoundError
You should put the logging jar into tomcat/lib or webapps/yourwebapp/lib depending on how it's used.

Re: Questions about Tomcat/Servlets
Obviously in both cases only the .class file can be run. What differs is when and how they get compiled. Your servlet's source is not monitored ever but your JSP source is. Therefore when the JSP source changes the container recompiles it and executes teh new .class file. In the case of a servlet, changing source is not detected but (if configured) changed .class file is. In order to have a new .class file you need to compile the .java file yourself. Servlet .class file is no different from HelloWorld.class file. It just requires some stuff on classpath in order to get compiled and it can't be run directly but is invoked by the servlet container. You can write your own servlet container if you want too. Make it an HTTP server. When a request for it is made (http://localhost/SillyServlet) have it load your servlet class by name (cast it to HttpServlet) and execute its init() and then its doGet() method with the right parameters. d. Kenny G. Dubuisson, Jr. wrote: Hello all again. I have 3 simple questions that I'd like to see if anyone knows (please let me know if this is off topic or not). 1) I'm working on teaching myself JSP/Servlets. I wanted to know if when a servlet is run the .class or the .java file is what got run. So I renamed one of Tomcat's example files (HelloWorldExample.class) to a *.bak. Once my test was done I renamed it back to the original file name. Now it won't run. Gives me a Apache Tomcat/4.0.5 - HTTP Status 503 - Servlet org.apache.catalina.INVOKER.HelloWorldExample is currently unavailable error. I thought it maybe had something to do with the java and class files having the same time stamp so I copied both from the original Tomcat distribution and it still won't run. Man I'm stuck on this one...any ideas? 2) How do you get a .class file when you create a .java Servlet file? I was hoping that if I delete a .class file and the .java file still exists, the .class file gets recreated/recompiled automatically by Tomcat. 3) What the heck does Jakarta mean?

According to the CallableStatement docs, you have to account for every ?
in your statement. There is 1 return status, 5 input parameters, and 5
output parameters: 1 + 5 + 5 = 11.

Re: Hooking up Tomcat to Apache
See below Peter Alvin wrote: Tomcat is running fine in standalone mode but I'm having difficulty hooking it up to Apache. I've configured Tomcat's server.xml file and I have an include file in Apache's httpd.conf file that points to a copy of the auto -generated tomcat-apache.conf file (where I've corrected the path to the mod_jserv.so module). When surf to www.mydomain.com/appName I get a Cannot find server page (interestingly, not a 404). If you don't mind, I have a few questions. 1) Fact1: When tomcat runs in standalone mode, its default port is 8080. Fact2: my auto-generated tomcat-apache.conf file has the line ApJServDefaultPort 8007. Question: Does that mean I have to manually start Tomcat on 8007 (instead of 8080) in order to handle the requests from Apache? No. 8007 is not the same as 8080 (obviously). 8080 is an HTTP connector that you can get to through a browser. 8007 port is for the AJP connector to send requests over. They must be different. You should see the 8007 port in your workers.properties file for the AJP connector. 2) Does the adaptor, mod_jserv, open up a TCP connection to Tomcat in order to pass requests? I guess so. This sounds inefficient. That's the 8007 port. 3) There is another line in the tomcat-apache.conf file that states ApJServManual on, which, according to the manual says this: Instruct jserv not to start the Tomcat process. Automatically starting Tomcat is not implemented yet. If that is true, how do I configure Tomcat to start automatically along with Apache? /etc/inittab for starting during system boot? My overall goal is to have only *.htm files (mydomain.com/fileXYZ.htm) handled by Tomcat. I think this is a typo. Tomcat should be handling the .jsp files and the HTML files should be left to apache to handle.

Yes this works because each Apache instance knows of and can forward to all Tomcat instances by the way of workers.properties file. d. Schnitzer, Jeff wrote: I have a conceptual question about load balancing Tomcat4.0.4 instances. I'm building a *very* high traffic site.

Re: Apache/Tomcat Connectors List
some of them come with the Tomcat distrib and some of them don't. That is, there are two kinds of connectors, those for Tomcat standalone and those for integrating Tomcat with Apache (or some other web server). The ones for Tomcat standalone and the Tomcat side of those for integrating Tomcat with Apache come with Tomcat, while the Apache side of those for integrating Tomcat with Apache don't. They have to be gotten separately, perhaps via the connectors distribution (which I think includes all sides of all connectors). http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/index.html Look on the left-hand side under connectors.

Re: How to abort the webapp load/deployment
You can try having a single servlet that has 'handlers' for it and so all requests go through it first and it dipatches them further to handlers. I have this setup and map the servlet to something like /handler and then for an action such as handler/AuthenticationHandler the request goes to 'handler' servlet and it figures out what AuthenticationHandler is and if it exists it forwards the request to it.

Re: mod_jk problem
Yeah I haven't found any way of doing load balancing without Apache either. My question was hopefull but you only confirmed my earlier findings :(. We're probably going with hardware SSL so I wouldn't need Apache to handle this and that's why I want standalone Tomcats (I was curious about their performance with SSL though). In any case you're right about not a lot of people worrying about this. It seems like load balancing is not very commonly used. Good luck, d.

I think the best solution is Apache + Tomcat though. It's undoubtedly cheaper/easier. So - you ready to install Apache yet? Breeze over to the Oreilly site and look for Apache Wrangler and something called LAMP. You'll find an article that will point you to a script that will download/install Apache + SSL (it even pre-configures it for you - whatever that means). If you have the option of using RPMs, I'd go with that option though. RPM == good (IMHO). One thing you will need to ensure is that your load balancing solution routes all requests for the same session back to the same Tomcat instance (like the balancing through Apache does).

I tried to use jspDetroy method but : I have no idea when exactly this is called I cannot use my index variable in it I hope I have been clear and someone has an idea on this Thanks Raphaël -BEGIN PGP SIGNATURE- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE9KqOoh2ITK4xBkFERAq38AJ9DYAEYGBOvQGwNO6RBinptbhHH5wCfcSkn iSDAXqcoa3ZVHQSFybECJ0E= =cHmv -END PGP SIGNATURE- -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- David Mossakowski [EMAIL PROTECTED] Instinet Corporation 212.310.7275 *** Disclaimer This message is intended only for the use of the Addressee and may contain information that is PRIVILEGED and/or CONFIDENTIAL or both.

Re: Question about context paths and IMG URL's
I always do this in my JSP pages: %=request.getContextPath()%/graphics/clear.gif This way whatever you have your servlet mapped to it will work d.

Or does that actually say relative to the context? I don't see how though, since this is just HTML and thus it means it's relative to the page (unless the servlet container/Tomcat does some magic to re-interpret the request?). -Original Message- From: Lin, Zhongwu [mailto:[EMAIL PROTECTED]] Sent: Friday, June 28, 2002 12:09 PM To: 'Tomcat Users List' Subject: RE: Question about context paths and IMG URL's It should be img src=images/foo.gif J -Original Message- From: Chris Bailey [mailto:[EMAIL PROTECTED]] Sent: Friday, June 28, 2002 12:22 PM To: Tomcat Mailing List Subject: Question about context paths and IMG URL's I seem to have confused myself about the proper way to specify an image location in HTML that my servlet spits out. If I have an images directory at the root of my webapp, is it safe to always do this: img src=/images/foo.gif Or, how does the context path attribute play into this? We always set our path to (our app is the only one running in the container). But, I'm wondering about this if we wish to make it a bit more generic so that we could just give a customer a WAR file and let them set it up in their container as they wish.

Re: load balance session
From what I read you don't share the session. The way it works (if it's set up correctly ) is that your jvmRoute in Engine section of Tomcat is appended to the sessionid and that's how the connector knows to which Tomcat the subsequent requests should be sent. If that tomcat dies the sessions on that server are lost but your application is accessible because the connector routes the requests to the tomcat that survived. d.
