Re: Stability of Tomcat 3.3 vs. 4.0
I would suggest Tomcat 4.0 because it is integrated into Jboss which gives you a MAJOR speed up between the servlet layer and the Jboss layer. Major speed up.

Catching NPE's in JSPs
Like a lot of people, sometimes I'll see a JSP error out with an NPE... In this case I have a JSP that pulls some stuff using request.getAttribute() and displays the info... I'm having a hell of a time finding the current culprit of my NPE... I've tried pulling out sections of code and reloading... Still having trouble... Tomcat4 seems to buffer slightly differently where with 3.x the NPE was closer to the code that was just output? Anyway, wondering if anyone has any insightful methods to track down NPEs in JSPs...

Coding Tags the Right Way
I have the Manning book, JSP Tag Libraries which I've been using to help develop some of my first tags. For their iterator tags that work with beans, they use a lot of reflection.

Anyone that has worked with tags have any insight as to how this design could negatively impact performance on the Web app? Hunter
Strange Tomcat - Apache Configuration
I am using Tomcat 3.2.3 in conjunction with JBoss and Apache in front... First off, my configuration works just fine. My problem is that from the Apache conf file, I don't see why it works. When I change it to what I think it *should* be, it doesn't work anymore... Here are some details: Apache 1.3.20 w/ mod_jk JBoss 2.4 w/ embedded Tomcat 3.2.3 Some env variables: JBOSS_HOME = /usr/local/jboss TOMCAT_HOME = /usr/local/jboss/tomcat I also have an old, inactive (i.e. not running) copy of Tomcat at /usr/local/jakarta-tomcat-3.2.2 Here is part of my *working* Apace conf file: VIRTUALHOST x.x.x.x DocumentRoot /server1/libmedia ServerName www.liberationmedia.com ServerAlias www.liberationmedia.com liberationmedia.com CustomLog /server1/libmedia/logs/apache.log combined ServerAdmin [EMAIL PROTECTED] Alias /libmedia /usr/local/jakarta-tomcat-3.2.2/webapps/libmedia Directory /usr/local/jakarta-tomcat-3.2.2/webapps/libmedia Options Indexes FollowSymLinks /Directory JkMount /libmedia/servlet/* ajp12 JkMount /libmedia/*.jsp ajp12 JkMount /libmedia/* ajp12 Location /libmedia/WEB-INF/ AllowOverride None deny from all /Location Location /libmedia/META-INF/ AllowOverride None deny from all /Location /VIRTUALHOST Here you see that the Directory directive is pointing at the INACTIVE version of Tomcat. This copy of Tomcat is not running. Changes to the files in it's webapps directory DO NOT change the running site, only changes to the files under the TOMCAT_HOME specified above do. If I change the directory directive to point to the real tomcat directory, Apache returns a not available error (as if Tomcat wasn't even started). This makes absolutely no sense to me and I don't feel comfortable with a configuration I don't understand. Any help is greatly appreciated.

Looks like you don't have stub classes of your ejbHome in your tomcat. Try
put those in your application's

Finding a Memory Leak in a Web Application
I think my application is leaking. Over time the size of the Java process grows but never shrinks back down. I'm not sure of the best way to find the leak. I can't afford expensive profiling tools like OptimizeIt, etc... It may be something as simple as a design flaw on my part... Here's my design: requests come into a servlet which creates vectors of objects from database data. These vectors are stored in the request scope and then I forward to a JSP page where the results are displayed from the Vectors. I assumed (incorrectly?) that since they were in the request scope they would be garbage collected after the request was over (which is when the page has been sent to the user, right?). Is this not the case? Any help/suggestions anyone has would be great! Hunter

If you're using Tomcat with Apache, try upping your max_threads parameter to match the max number of child processes your Apache installation allows (MaxClients in httpd.conf). If you're running standalone, up max_threads to a reasonable number you don't think you'll hit.

I already mentioned this to Dan Milstein. It should really be checked, if that way of flushing to the physical disk (and not only to the file system cache which should be enough) is really needed. The problem becomed more important due to the fact, that the actual production release incorrectly documents the existence of a log level warn. In 3.2.1 this does not exist. The header file for the logging declares only: #define JK_LOG_DEBUG_LEVEL 0 #define JK_LOG_INFO_LEVEL 1 #define JK_LOG_ERROR_LEVEL 2 #define JK_LOG_EMERG_LEVEL 3 #define JK_LOG_DEBUG_VERB debug #define JK_LOG_INFO_VERBinfo #define JK_LOG_ERROR_VERB error #define JK_LOG_EMERG_VERB emerg and if you use any undeclared log level (as e.g. warn) the code falls through to debug. So using warn you actually produce tons of debug output, each line calling fdatasync to flush to disk. We had the same problem on the first day of a heavy load production system and had some hard hours to find out. I think the second point (incorrect log level warn) is corrected in the next release (by changing documentation and default - not code), the first thing, throwing out fdatasync - should still be done.

Re: setting up tomcat and apache to run together
Title: Re: setting up tomcat and apache to run together Greg- There is quite a bit of documentation on using Tomcat with Apache. You need to use mod_jk with Apache to redirect the requests. Look up the docs, I think youll figure it out. Good choice of platform BTW. :-) Hunter From: Greg Chakmakian [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] Date: Wed, 18 Apr 2001 11:48:45 -0400 To: [EMAIL PROTECTED] Subject: setting up tomcat and apache to run together Bear with me, I know you all have probably already been through this one before. I have Apache (for Darwin/Mac OS X) and Tomcat 3.2.1. They both run great by themselves; apache on port 80 and tomcat on 8080. I want to setup the two so that if I go to a jsp page on Apache it will use tomcat to process the jsp pages; i.e - http://www.apache.org/test.jsp gets processed by tomcat even though its being access through apache. I know I can turn off apache and reconfigure tomcat so that it runs off of port 80, but I would rather do it the other way. Like I said, I know this has probably been discussed and I apologize for being repetitive. I couldn't find any information on how to do this. Any help or direction you all could give would be greatly appreciated. -greg Healant Web Developer [EMAIL PROTECTED] [EMAIL PROTECTED] 336-370-0604 x111
Serving with Virtual Hosts w/o a Context Name - ?
Here's my setup: Tomcat 3.2.1 with Apache 1.3.19 on Red Hat 6.2. We have about 50 IP based virtual hosts, some of which use Tomcat, others which do not. Is it possible to setup Tomcat to serve a virtual host the contents of a context without the context name having to be in the URL? I.e. www.somedomain.com goes directly to the context mywebapp instead of it having to be www.somedomain.com/mywebapp/ ? I thought I saw a site that did this but I wasn't sure, especially since I have Apache in the mix and all the virtual hosts... The FAQ-O-Matic answer is to put in a redirect. That works fine, just seems less elegant. Any ideas? Hunter

Subject: RE: Confusing Problem with SQL Query in Tomcat
Some data types(char) are fixed length on some databases. I'm not familiar with postgres, but you may want to try 'where upper(rtrim(name)) = upper(?)' to trim any trailing spaces. I have run into cases where in a char(10) field,'ABC' is not equal to 'ABC ', which is what is actually stored. Other data types, like varchar, only store 'ABC' and thus would work.
Also, rtrim() may slow down your query so you may want to right pad the string you are passing in to be the correct length if you want to use a char() type.

I have a servlet called marketCustomerVendorController that is mapped to /marketCustomerVendorController as seen here from web.xml: servlet-mapping servlet-namemarketCustomerVendorController/servlet-name url-pattern/marketCustomerVendorController/url-pattern /servlet-mapping On the dev box, it works great. Yesterday I tried to push the WAR (generated by Ant via ./build dist) out to the production box. Does your dev box run Tomcat standalone and your production box run Tomcat behind Apache? If so, the most likely reason for this is that the Apache connector is totally ignorant of anything you define in web.xml -- you'll have to modify the tomcat-apache.conf file to include any additional forwarding you want.
