Re: Tale of two servers
More details please. Are both machine running the same version of Java. Are they both connecting to an external database? Exact same versions of Tomcat 5.5.x ?

Both servers are programmatically queried by users and are bombarded with thousands of requests. One of the servers responds much more quickly than the other. In fact, one of them causes timeouts. The offender is a super duper new dell desktop with 4gb of ram, etc. It's running java 1.5 and is committed to nothing by tomcat. The winner is a rinky-dink 2 year old laptop with little ram, and lots of spyware sucking out cpu.

Help with configuring
Hello. I just installed Apache 2.0.48 and Tomcat 5.0.16 (using a Java 2 1.4 SDK) on Windows XP Home (It's a development environment, on my laptop). I'm having a bit of trouble getting the two to play together. I installed both of them using the provided binaries off the Apache project servers, and both seem to be running, there are tray icons both showing green, no obvious errors. In addition, when I navigate to http://localhost, I can see the default Apache page. I have CATALINA_HOME and JAVA_HOME environmental variables set as well. I can't access the Tomcat configuration page (the program files group links to http://127.0.01/admin as the configuration page, but it shows up as a 404). I haven't done any config other than run the installation routines. What other things do I need to set up and/or check? I did read the manual, but all it said was that for Windows, I should just run the installation routine. Should I downgrade to Apache 1.3.29, or anything else? Thanks in advance. -Vinny - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Help with configuring
Thank you for the link. I managed to get everything set up (I used mod_jk). Without the link, I wouldn't have known mod_jk was even needed... Although, I have a few tiny questions: When I navigate to http://localhost, I get a Tomcat home page (not the Apache default one). http://localhost/admin also works now. But it seems that Apache is now using Tomcat's help site as root, instead of %Apache Directory%/htdocs, the default earlier. In addition, when I look at XP's Services menu, it does NOT show the Apache webserver as Started. It shows Tomcat has started, though. And, to make matters worse, the Apache tray icon shows red, and when I bring up the Apache monitor and click the Start button, it says an error has occured, unable to start. So, what have I done here? Not that I'm complaining; I can now test my servlets and JSP pages before sending them to the production server. Why is Apache the http server giving errors, when obviously it's serving pages as localhost? I fixed up everything as it says in the Wiki, and by all accounts, the default root should still be in the Apache http server /htdocs/ directory. So, what's wrong with this picture? Also, where do I dl the javax.servlet class files for the java compiler? Thanks -Vinny. Vinny, I don't know if anyone responded to you. Try the following link for instructions for either mod_jk or mod_jk2. http://nagoya.apache.org/wiki/apachewiki.cgi?TomcatWeb I just went through the instructions for mod_jk2 and got up and running in a few minutes. I'm using: Windows 2000 server Tomcat 4.1.29 Apache 2.0.48 J2SDK 1.4.2 Mysql 4.1.0 On Fri, 26 Dec 2003 13:00:12 -0600, Vinny wrote: Hello.

omegacms
Hello, has any one tried installing omegacms on tomcat? I have a fresh install of tomcat 3.2.2 that is working fine on redhat linux 7.1. The app cannot find it's properties file no matter where I put it. Unfortunately, it seems to be closed source so I can't figure out where it is trying to look for the conf.properties file. The error message I get from Tomcat is : config.properties not found when trying to load properties: config.properties in ./bin/../lib/test//usr/java/jdk1.3.1/ The docs say to have config.properties in the classpath, so I put it in myApp/WEB-INF/classes, I even tried putting it in TOMCAT_HOME/lib to no avail. Why Oh Why don't people use the jsp/servlet specs on directory structure organization? Anyone experienced in making this thing work? Thanks in Advance Vincent
Re: omegacms, thanks and a new problem: compile errors
Thank you very much, I had to explicitly put the omega jar and the directory containing the property file in my unix shell's classpath. Now the problem I'm running into is that some pages are getting compile error messages. 2001-06-19 12:07:40 - Ctx( /omega ): JasperException: R( /omega + /admin/hello.jsp + null) Unable to compile class for JSP/usr/local/jakarta-tomcat-3.2.2/work/localhost_8080%2Fomega/_0002fadmin_0002fhello_0002ejsphello_jsp_0.java:61: Incompatible type for method. Can't convert void to char[]. out.print( out.print(!) ); the hello.jsp file contains: h2Hello World %=out.print(!) % /h2 what's going on? Thanks again in advance. Randy Layman wrote: If you're on UNIX, add it to TOMCAT_HOME/classes, if you're on NT you'll need to modify the tomcat.bat file so that Tomcat adds this directory to its automatically built classpath. Another option it to add the conf.properties to the CLASSPATH environment variable. In either case, there are some ways that you can request resources that cause the wrong class loader to be used, which it seems is happening here.

which version for production?
I'm designing some jsp and servlet apps that will be used to extend some of the functionalities of php-based site on linux platform. I have tomcat 3.2 b6 working fine, should I stay with this or try to 4.0 beta? How is 3.2 vs 4.0 in terms of 1. performance 2. scalabilty 3. memory 4. Stability I'm trying to keep everything very low cost (free) in the great tradition of LAMP (Linux Apache Mysql Php) IBM vs Sun/Blackdown (currently using blackdown jdk 1.3) Jikes vs other free compilers? Comments are very welcome Thanks in advance
