Discussion on Apache with Apaphe Tomcat

I am doing some research on the pros and cons of
either using Apache with Apaphe Tomcat on a live production server
or
Apaphe Tomcat on its own on a live server.
Anyone knows any urls to some documentation on the subject
Con (Apache with Apaphe Tomcat)
I personally feel that Apaphe Tomcat on its own is a better sollution
because the OS will use more memory to run both application (Apache with Apaphe Tomcat) simultanuesly.

I've heard on many occasions that Apache can serve static content (html) faster than Tomcat. So if you are not concerned with Java the you'd be better off with just Apache. Tomcats main focus is to serve dynamic Java content, it just so happens that it can serve static content as well.
here is one link,

Apache HTTPd + 2 Tomcats with BlazeDS

The web architecture that we have is quite simple, it is a single Apache HTTPd server that is communicating with 2 Tomcat servers using mod_jk. The configuration is made so one Tomcat is in a waiting state in case the other Tomcat server crashes (or bounce).
How can I configure BlazeDS to support this configuration? Is sharing the HTTPSession between the two Tomcats enough for BlazeDS?
I would like the simplest solution possible, I know about BlazeDS clustering possibilities with JGroups but it seems not adapted to multi-environments (DEV/QA/PROD) sites because we have to configure stuff inside the web app.
In short, do BlazeDS only need HTTPSession sharing between Tomcats or is there some other requirements?

As far as my understanding goes there should be no reason to use JGroups unless you are using messaging.
If you are storing session data on the server you will need to using Tomcat clustering other wise you shouldn't even need that.
We are using a similar setup with HTTPd and multiple JBoss servers for high availability/scalability. We are not using messaging so we didn't configure JGroups. We don't have JBoss clustering enabled because we don't have any data to replicate between the JBoss nodes.
I have run several load tests using JMeter and everything runs happily when JBoss nodes are added or removed under load.
Something to note if you are using recent builds of BlazeDS and you want to run 2 or more Tomcat servers concurrently you will need to enable Sticky Sessions with mod_jk and Tomcat other wise recent builds of BlazeDS may start throwing exceptions. This change was introduced to prevent subsequent client requests from needlessly creating new sessions. As it turns out this is a bit of an issue when doing loadbalancing unless Sticky Sessions are used.
Hope some of that information helps,

Integrating Apache with Tomcat?

Anyone have a guide to integrating Apache with Tomcat using mod_jk?
I followed some guides online, but they all seem really dated with some obscure references. This seems like it should be on the top of the list....

Hi Alan.
I've discovered the exact same problem.... 0.0.0.0 instead of 127.0.0.1
You've obviously not had any replys here, but di you end up working it out on your own?

Apache with Tomcat cluster

Hi, I integrated Apache with Tomcat Cluster on Windows 2000. I instalated mod_jk2.dll, created workers2.properties and configurated server.xml in Tomcat instances. If I try to reach my .jsp file, e.g. http://localhost/root/main.jsp, I get follow message from Tomcat: source root/main.jsp is not available. What�s wrong? Can anybody help me? Apache version: 2.0.47, Tomcat: 1.4.27

Well, the first order of business is to determine exactly where main.jsp is located. If it is at <CATALINA_HOME>/webapps/main.jsp, then it should be at http://localhost:8080/main.jsp. Bypass Apache and verify that you can get to the Tomcat specific pages first.
Basically, we're trying to determine a) the correct URL and b) whether the problem is with Tomcat itself, or with the connections between Apache and Tomcat.
Essentially, we can't tell you where your configuration is incorrect until you tell us what your configuration is. :)

Apache with JServ or Tomcat?

What�s your preferences in relation with JSP web server: Apache with JServ module (or another want you considerer better) or Jakarta-tomcat?
I have used both, but I don�t know exactly which one I should use in my new job.
Thank you everybody and good luck!

JServ, while fine in its time, is now outdated and will not be updated. If you want to use any features added to the JSP or Servlet API's in recent years, you need to use Tomcat.

Adv. of using apache with tomcat??

can anyone pl tell me the advantages of using Apache with Tomcat in comarison to other web servers?
Thanks

The biggest advantages are that they are open source, so you don't have to pay a huge licence fee, and they are very stable. I don't know how they compare for speed - I know Apache is lightning when it comes to serving flat pages, there are no benchmarks yet for the new Tomcat because it was only released last monday. You can run them on linux or another unix variant, so they are more likely to be secure (windows servers are horrendously open to attack) and stable.

UNSUPPORTED : The way it works Apache with OC4J via AJPV13 with mod_jk

RDBMS Version: 8.1.7.x
Operating System and Version: SUSE Linux 7.2 / Win NT/2k/XP
Product (i.e., OAS, IAS, etc): 9ias 1.0.2.2 OC4J 9.0.2.0.0
Product Version:
JDK Version: 1.3.1
Error number:
UNSUPPORTED : The way it works Apache with OC4J via AJPV13 with mod_jk
We dont want to use the lame and old mod_jserv so we want to use oc4j but in connection with Apache.
This is like mod_oc4j in the Oracle 9ias Release 2
This guide is for advanced users !
Step-by-Step :
1) get Tomcat 3.3 for linux or nt with Apache module mod_jk
http://jakarta.apache.org/builds/jakarta-tomcat/release/v3.3/bin/
2) add mod_jk module to httpd.conf (9ias) and comment all mod_jserv, dms, oproc, ojsp ....
LoadModule jk_module libexec/mod_jk.so
Include mod_jk.conf
3) edit mod_jk.conf
JkMount /*.jsp ajp13
JkMount /servlet/* ajp13 JkMount /servlets/* ajp13
<Location "/WEB-INF/"> AllowOverride None
deny from all
</Location>
3) edit workers.properties
workers.tomcat_home=/opt/oracle/ias/oc4j/j2ee/home
workers.java_home=/usr/java
worker.list=ajp13
worker.ajp13.port=8009 worker.ajp13.host=localhost worker.ajp13.type=ajp13
4) edit http-web-site.xml (oc4j)
<web-site host="localhost" port="8009" protocol="ajp13" display-name="Oracle9iAS Containers for J2EE HTTP Web Site">
5) start oc4j
java -verbose -jar oc4j.jar
6) start apache (look in error_log)
apachectl startssl
7) try to request a jsp page or servlet ..
http://localhost:7777/test.jsp
8) good luck it works fine .. !!

Thanks for the tip Mathias, it's always good to see people trying out experimental things with the products.
We're providing a new module (mod_oc4j) with our Oracle9iAS Release2 product to do this directly from the Oracle HTTP Server (Apache). We've re-written bits and pieces of the module to improve it's performance. Likewise, we've also integrated mod_oc4j with our HA story so it will be notified when new OC4J instances are brought online or if existing ones go down, enabling it to actively route requests around the available OC4J instances.
Thanks again!

paths with spaces in them are a problem. surround them with quotes and see if that helps.
why does the Java /bin appear twice?
why don't you use the JAVA_HOME variable that you set? don't repeat yourself.

Integrating Web server (eg Apache) with the application server

I am thinking a project in which I use more static HTML files than JSPs. One way is to use an Apache server to display those HTML files (it should be faster), and deploy the JSPs into the J2EE server; another way is just simple to change the web container�s port to 80 (of the PE 8), and wrap all the files into a war file and deploy it into the application server.
So can someone advise my which way is better? And if I use the first one, I�d like to know if it is the same way to integrate Apache with Tomcat.
Thank you very much!

In the past there has been a belief that the Apache web server serves static content faster than tomcat. Site managers would configure apache to deliver static content and integrate a web container to handle the dynamic content. I believe this argument is losing steam as tomcat gets better. I guess the only way you will know for sure is to deploy your application in PE 8.0 and then in an apache/web container configuration and do some benchmarking. I have no such benchmark data to compare and I base my comments on what I have read in newsgroups over the past months. Personally, I would opt for the app server only setup just to ease configuration. Others may have a different opinion.

Apex with XE10g/Tomcat 6.0.13 PDF Print with Apex FOP.WAR

Apex with XE10g/Tomcat 6.0.13 PDF Print with Apex fop.war/apex_fop.jsp
Hello,
Excuse me bad english.
I have a problem with Oracle XE and Printing from Reports over Tomcat 6.0.13.
I have update Oracle XE with Apex 3.1 and it works fine.
Now i have tried to Print a report to PDF. So i have deployed the FOP.WAR from Apex Utilities under Tomcat.
I see in Tomcat Manager http://localhost:8888/manager/html/list that the FOO
has been deployed and is running.
If i try to print then i get this Message down to this page.
Can anybody give me a hint to solve this problem???
Hint
To resolve the problem i have installed Oracle OC4J with same Port and deployed
the same foo.war file.
Then works and all printing from Oracle Apex work fine and okay.
So i thing the Apex and Oracle work correct.
But we have a small Application so i would prefer to work with Tomcat a application Server.
Becaus of previous Errors have copied some *.jar files to C:\tomcat6.0.13\lib
but i thing this is not the Problem.

You know, it also helps if you take the time to respond to requests for more information.

I'm sure there were lots of other people wondering exactly which problem you were having, and if you don't answer, but keep creating new posts asking for help, people decide it's just not worth their time and effort to help you.

WLS with the HttpClusterServlet or Apache with proxy plug-in?

I'm newbie with WebLogic Server cluster.
Please tell me which is better for load balancing for WLS cluster? WLS with the HttpClusterServlet or Apache HTTP Server Plug-In? And which is recommended for production environment?
Many thanks.

Apache with plug-in, as this is easier configurable.
For the HttpClusterServlet all the configuration goes into web.xml which has to be packaged as a war file and deployed to WebLogic.
When any change is needed you have to edit the web.xml file, package it again and redeploy it.
An example of the Apache plug-in set-up can be found here: http://middlewaremagic.com/weblogic/?p=7795 (the load balancing section)
Or if you want to use the Oracle Web-Tier (which includes a precompiled Apache HTTP server): http://middlewaremagic.com/weblogic/?p=7819 (the load balancer section)

Configuring JDBC connector with my Tomcat server

I realize this may be a dumb question, but I'm having trouble configuring my JDBC connector with my tomcat server. I'm trying to run a simple servlet that will access mysql database. I am almost certain its throwing an exception on the line:
Class.forName("com.mysql.JDBC.Driver");
I have a feeling the tomcat class path isn't finding the connector jar file.
Any help would be greatly appreciated.
Brian

I am almost certain its throwing an exception on the line:
Class.forName("com.mysql.JDBC.Driver");If it's a ClassNotFound exception or the like, then yes. Post the exception and stack trace if you need confirmation of this.
I have a feeling the tomcat class path
isn't finding the connector jar file.That's what I think too. Did you ensure that the MySQL driver JAR file was in the classpath?
It will need to be in common/lib under Tomcat, or WEB-INF/lib under your application.
For a more portable application you should use JNDI to obtain database connection resources, in which case you would want the JAR to be under common/lib.

Compiling Apache with PERL module on Solaris 8

Hi there,
After the Richard's reply, I found the Apache sources on the intallation CD 2/2. And after a while I successful compile the apache WITH ITS STANDARD modules with the following command:
$ ./configure --prefix=/usr/apache \
--enable-module=most \
--enable-shared=max \
--with-layout=Solaris
$ make
$ make install
But the above "configure" does not compile the companion mod_perl. So, I tried:
... $ ./configure --prefix=/usr/apache \
--enable-module=most \
--enable-shared=/usr/src/apache/mod_perl/src/modules/perl/mod_perl.c \
--add-module=max \
--enable-shared=max \
--with-layout=Solaris
but the above command just copies the "mod_perl.c" to the diretory
"usr/src/apache/src/modules/extra"
missing the corresponding *.h
Then trying
$ make
The compilation fails because of ALL the
files on the directory
/usr/perl5/5.00503/sun4-solaris/CORE
are not found.
Any Hint?
Thanks in advance
C�sar

have you tried downloading the source from apache.org and compiling it?
ive installed apache on sol8 many times, but all from apache.. not from the cd..
