Problem in configuring tomcat and apache
I am using mod_jk to configure tomcat and apache. In the server.xml file in /TOMCAT_HOME/conf, I have added this line:
<Listener className="org.apache.jk.config.ApacheConfig" modJk="/TOMCAT_HOME/mod_jk/mod_jk.so" />
And when I restart the tomcat, I get this error:
Caused by: java.lang.RuntimeException: Unable to create path to config file :
/usr/local/tomcat/apache-tomcat-5.5.15/conf/auto/mod_jk.conf
What this error is and how it will be removed. Any suggestion?
Joseph
Seems like a filesystem user rights problem. Perhaps tomcat is running as a seperate user and this user has no rights to write to one of the subdirectories?

Configuring tomcat and apache on the same system
i need to configure tomcat and apache on the same system.
first i have configured apache and it is working well.
Next is have configured tomcat and it is working well.
i need to interlink tomcat and apache. so i downloaded jk connector and i have configured it.
i gave an entry in the httpd.conf as
Include /tomcat/conf/auto/mod_jk.conf
i have copied the file mod_jk.so to /usr/local/apache/libexec/
went i start apache after the entry is given it gives the error like this
cannot load /usr/local/apache/libexec/mod_jk.so into server: ld_so.1. /usr/local/apache/bin/httpd: fatal : libgcc_s.so.1 : openfailed : no such file or directory in linux
please help to configure this.
i have done every thing as it is in apache.org documentation. please give the complete configuration. some say that tomcat is not compiled according to apache1.3. but i configure jk connector as --with-apxs=/usr/local/apache/bin/apxs
send me the reply
thankqs in advanceHi,
I'm working in a linux machine and choose to use also two different users. Of course I'm using two different ORACLE_HOME directories.I think that the best approach.Just a question ,are you keeping the "GROUP" same or different?

Hello,
Has anybody ever gotten tomcat and apache working properly? I'm having a hell of a time with it. I have them working independently, and have JK2 installed (made a package for it). I used the tomcat 4.1 package from incoming...
I can post configs and such if anybody thinks they can help. Right now, this is just a probe to see if anyone thinks they can help. I need a break from it, been scrapping with it for three hours now.
Once I get this working, I'll post a howto to the Wiki, I promise. :-D
Thanks for any info,
DustyThanks for the info so far, it's still not working though... here's what I'm getting:
chane wrote:I might be able to help a bit. I have apache 2.x and Tomact 4.1.29 running with JK2.
I've got apache 2.0.48, tomcat 4.1.27, and jk2 2.0.2. Tomcat is from incoming, I built jk2 from ABS myself; It puts mod_jk2.so in /usr/lib/apache.
in httpd.conf added a module:
LoadModule jk2_module lib/apache/rh72-2.0.2-mod_jk2.so
I've got:
LoadModule jk2_module lib/apache/mod_jk2.so
I think that's right; it seems to be loading the module (see error messages below)
in the same directory (as httpd.conf) there is the workers2.properties file:
I've tried various versions of that file. I just tried it with the one you gave copy-pasted into place, same problems.
In the tomcat server.conf there is a connector for Coyote/JK2 AJP 1.3, make sure this is not commented and is on port 8009.
I think I've got that set up properly. Isn't there some command I can use to test if there is a service running on port 8009?
Anyway, when I go to http://localhost:8080/examples/jsp, for example, it works with tomcat. But if I go to http://localhost/examples/jsp I get a 404 not found; apache isn't forwarding the request to tomcat, for whatever reason.
In /var/log/httpd/error_log, I've got this info:

I can't tell if it isn't finding workers2.properties in the right place (why look in /usr/conf), or if its looking in two places and then not finding the shm file??
Do you have anything in ${TOMCAT_HOME}/conf/jk2.properties? All the stuff I've seen online wants me to add stuff to that file, but its never the same stuff.
Thanks very much,

Upgrade the default Tomcat and Apache
Hi
Is there a working and correct way to upgrade and run a Tomcat and Apache server of your pick instead of the pre installed versions in OSX 10.4.8 server.
Meaning that i want to start and admin them throught Server Admin interface, and making Jboss notice the new Tomcat aswell.
MikaelIf you're asking here, the answer is probably no.
It is possible to build and install later versions of all the Mac OS X Server-bundled apps, including Apache, Tomcat, postfix, bind, etc., etc., but in most cases once you do you lose the ability to drive them via Server Admin.
Server Admin knows what it knows - more importantly it doesn't know any of the features of later versions of the apps (it may work with point released (e.g. Apache 1.3.20 -> 1.3.30, but it won't work with major versions like 1.3 -> 2.0).
So if you go that way you're on your own as far as configuring and maintaining the service is concerned.
Leopard (10.5) will include later versions of these apps if you're prepared to wait. -
Run tomcat and apache together
how can i do that tomcat 4.0.6 and apache work at same time? , it is to say, how get Tomcat to runs application server while leaving your static pages on Apache under standard distribution for linux, and do not uses the port 8080, if not, that jsps runs in the domain, example:
i don't want this:
http://mydomain:8080/index.jsp
i want this:
http://mydomain/index.jsp
thanks in advanced.i have encountered a similar problem, here's a useful URL:

Tomcat and apache bundle in Solaris10
I am a little confused between apache and apache2 bundled with Solaris10
There is
/usr/apache/tomcat/
/usr/apache2/
I have apache2 web server started on my sol10 instance but there is no tomcat container
How do I configure tomcat to run with apache2 on a default install of solaris10? Must I migrate the tomcat that comes with apache or install a new version of tomcat? or ??
thanksThe stuff that ships with Solaris is primarily used by Solaris utilities.
If you want to use it for your own purposes then you're better off installing your own version somewhere in the fileystem and then configure accordingly.
A patch to the supplied stuff could break your custom config.

Tomcat and Apache/Tomcat is the same?
Hello,
I�m new to jsp and somedays ago I asked here a question and the solution was about installing Apache or Apache/Tomcat.
Now, my question is the following.
When I started to learn jsp , what I did were to install Tomcat. After reading some questions in these forums I do not know what is the difference between the installation of Tomcat and the installation of Apache/Tomcat.
What I have done for the moment is to have a server with Apache and another server for my jsp pages with Tomcat....
Does it means that it is possible to integrate two installations in only one server and to run all the pages in the same server? Where can I find information about that?
Thanks a lot and regards,
PattyTomcat has an HTTP listener built in, so you don't necessarily need Apache to run Tomcat and serve up HTML, JSP, and servlets.
But if you want to have Apache handle static HTML and forward servlet/JSP requests to Tomcat, there are docs at the Tomcat site to tell you how to bolt Tomcat onto Apache.
The Wrox book "Professional Apache Tomcat" has good instructions, too. I've done it successfully many times. - MOD -
Problem with Configuring Tomcat for running jsp web applications..Plz HELP
I am using Tomcat 5.5 and Jdk 1.5.0_12 and Oracle 10g. I am using jdbc-odbc bridge connection
to connect to the database. I have placed my project folder called
tdm under the webapps folder in Tomcat. This 'tdm' folder consists of
a collection of html pages,jsp pages and images of my project. Also I created a
WEB-INF folderand in that I have lib folder which contains catalina-root.jar
, classes12.jar and nls_charset.jar files. And also in the WEB-INF folder I have the web.xml
file which looks like this

By default, a non-SSL HTTP/1.1 Connector is established on port 8080.
You can also enable an SSL HTTP/1.1 Connector on port 8443 by
following the instructions below and uncommenting the second Connector
entry. SSL support requires the following steps (see the SSL Config
HOWTO in the Tomcat 5 documentation bundle for more detailed
instructions):
* If your JDK version 1.3 or prior, download and install JSSE 1.0.2 or
later, and put the JAR files into "$JAVA_HOME/jre/lib/ext".
* Execute:
%JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA (Windows)
$JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA (Unix)
with a password value of "changeit" for both the certificate and
the keystore itself.
By default, DNS lookups are enabled when a web application calls
request.getRemoteHost(). This can have an adverse impact on
performance, so you can disable it by setting the
"enableLookups" attribute to "false". When DNS lookups are disabled,
request.getRemoteHost() will return the String version of the
IP address of the remote client.

<!-- Defines a cluster for this node,
By defining this element, means that every manager will be changed.
So when running a cluster, only make sure that you have webapps in there
that need to be clustered and remove the other ones.
A cluster has the following parameters:
className = the fully qualified name of the cluster class
name = a descriptive name for your cluster, can be anything
mcastAddr = the multicast address, has to be the same for all the nodes
mcastPort = the multicast port, has to be the same for all the nodes
mcastBindAddr = bind the multicast socket to a specific address
mcastTTL = the multicast TTL if you want to limit your broadcast
mcastSoTimeout = the multicast readtimeout
mcastFrequency = the number of milliseconds in between sending a "I'm alive" heartbeat
mcastDropTime = the number a milliseconds before a node is considered "dead" if no heartbeat is received
tcpThreadCount = the number of threads to handle incoming replication requests, optimal would be the same amount of threads as nodes
tcpListenAddress = the listen address (bind address) for TCP cluster request on this host,
in case of multiple ethernet cards.
auto means that address becomes
InetAddress.getLocalHost().getHostAddress()
tcpListenPort = the tcp listen port
tcpSelectorTimeout = the timeout (ms) for the Selector.select() method in case the OS
has a wakup bug in java.nio. Set to 0 for no timeout
printToScreen = true means that managers will also print to std.out
expireSessionsOnShutdown = true means that
useDirtyFlag = true means that we only replicate a session after setAttribute,removeAttribute has been called.
false means to replicate the session after each request.
false means that replication would work for the following piece of code: (only for SimpleTcpReplicationManager)
<%
HashMap map = (HashMap)session.getAttribute("map");
map.put("key","value");
%>
replicationMode = can be either 'pooled', 'synchronous' or 'asynchronous'.
* Pooled means that the replication happens using several sockets in a synchronous way. Ie, the data gets replicated, then the request return. This is the same as the 'synchronous' setting except it uses a pool of sockets, hence it is multithreaded. This is the fastest and safest configuration. To use this, also increase the nr of tcp threads that you have dealing with replication.
* Synchronous means that the thread that executes the request, is also the
thread the replicates the data to the other nodes, and will not return until all
nodes have received the information.
* Asynchronous means that there is a specific 'sender' thread for each cluster node,
so the request thread will queue the replication request into a "smart" queue,
and then return to the client.
The "smart" queue is a queue where when a session is added to the queue, and the same session
already exists in the queue from a previous request, that session will be replaced
in the queue instead of replicating two requests. This almost never happens, unless there is a
large network delay.
-->
<!--
When configuring for clustering, you also add in a valve to catch all the requests
coming in, at the end of the request, the session may or may not be replicated.
A session is replicated if and only if all the conditions are met:
1. useDirtyFlag is true or setAttribute or removeAttribute has been called AND
2. a session exists (has been created)
3. the request is not trapped by the "filter" attribute
The filter attribute is to filter out requests that could not modify the session,
hence we don't replicate the session after the end of this request.
The filter is negative, ie, anything you put in the filter, you mean to filter out,
ie, no replication will be done on requests that match one of the filters.
The filter attribute is delimited by ;, so you can't escape out ; even if you wanted to.
filter=".*\.gif;.*\.js;" means that we will not replicate the session after requests with the URI
ending with .gif and .js are intercepted.
The deployer element can be used to deploy apps cluster wide.
Currently the deployment only deploys/undeploys to working members in the cluster
so no WARs are copied upons startup of a broken node.
The deployer watches a directory (watchDir) for WAR files when watchEnabled="true"
When a new war file is added the war gets deployed to the local instance,
and then deployed to the other instances in the cluster.
When a war file is deleted from the watchDir the war is undeployed locally
and cluster wide

I have set the context path to /tdm in the server.xml file. Should this be placed in context.xml?
My first page in the project is called Homepage.html. To start my project I give http://localhost:5050/tdm/homepage.html
in a browser. Here I accept a username and password from the user and then do the validation in
a valid.jsp file, where I connect to the database and check and use jsp:forward to go to next pages
accordingly. However when I enter the username and password and click Go in the homepage, nothing is
displayed on the next page. The URL in the browser says valid.jsp but a blank screen appears.
WHY DOES IT HAPPEN SO? DOES IT MEAN THAT TOMCAT IS NOT RECOGNIZING JAVA IN MY SYSTEM OR IS IT A PROBLEM
WITH THE DATABASE CONNECTION OR SOMETHING ELSE? I FEEL THAT TOMCAT IS NOT EXECUTING JSP COMMANDS?
IS IT POSSIBLE?WHY WILL THIS HAPPEN?
I set the JAVA_HOME and CATALINA_HOME environment to the jdk and tomcat folders resp.
Is there any other thing that I need to set in classpath? Should I have my project as a
WAR file in the webapps of TOMCAT or just a folder i.e. directory structure will fine?I am using Tomcat 5.5 and Jdk 1.5.0_12 and Oracle 10g. I am using jdbc-odbc bridge connection
to connect to the database. I have placed my project folder called

<!-- A "Service" is a collection of one or more "Connectors" that share
a single "Container" (and therefore the web applications visible

<!-- A "Connector" represents an endpoint by which requests are received
and responses are returned. Each Connector passes requests on to the
associated "Container" (normally an Engine) for processing.
By default, a non-SSL HTTP/1.1 Connector is established on port 8080.
You can also enable an SSL HTTP/1.1 Connector on port 8443 by
following the instructions below and uncommenting the second Connector
entry. SSL support requires the following steps (see the SSL Config
HOWTO in the Tomcat 5 documentation bundle for more detailed
instructions):
* If your JDK version 1.3 or prior, download and install JSSE 1.0.2 or
later, and put the JAR files into "$JAVA_HOME/jre/lib/ext".
* Execute:
%JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA (Windows)
$JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA (Unix)
with a password value of "changeit" for both the certificate and
the keystore itself.
By default, DNS lookups are enabled when a web application calls
request.getRemoteHost(). This can have an adverse impact on
performance, so you can disable it by setting the
"enableLookups" attribute to "false". When DNS lookups are disabled,
request.getRemoteHost() will return the String version of the
IP address of the remote client.

<!-- Defines a cluster for this node,
By defining this element, means that every manager will be changed.
So when running a cluster, only make sure that you have webapps in there
that need to be clustered and remove the other ones.
A cluster has the following parameters:
className = the fully qualified name of the cluster class
name = a descriptive name for your cluster, can be anything
mcastAddr = the multicast address, has to be the same for all the nodes
mcastPort = the multicast port, has to be the same for all the nodes
mcastBindAddr = bind the multicast socket to a specific address
mcastTTL = the multicast TTL if you want to limit your broadcast
mcastSoTimeout = the multicast readtimeout
mcastFrequency = the number of milliseconds in between sending a "I'm alive" heartbeat
mcastDropTime = the number a milliseconds before a node is considered "dead" if no heartbeat is received
tcpThreadCount = the number of threads to handle incoming replication requests, optimal would be the same amount of threads as nodes
tcpListenAddress = the listen address (bind address) for TCP cluster request on this host,
in case of multiple ethernet cards.
auto means that address becomes
InetAddress.getLocalHost().getHostAddress()
tcpListenPort = the tcp listen port
tcpSelectorTimeout = the timeout (ms) for the Selector.select() method in case the OS
has a wakup bug in java.nio. Set to 0 for no timeout
printToScreen = true means that managers will also print to std.out
expireSessionsOnShutdown = true means that
useDirtyFlag = true means that we only replicate a session after setAttribute,removeAttribute has been called.
false means to replicate the session after each request.
false means that replication would work for the following piece of code: (only for SimpleTcpReplicationManager)
<%
HashMap map = (HashMap)session.getAttribute("map");
map.put("key","value");
%>
replicationMode = can be either 'pooled', 'synchronous' or 'asynchronous'.
* Pooled means that the replication happens using several sockets in a synchronous way. Ie, the data gets replicated, then the request return. This is the same as the 'synchronous' setting except it uses a pool of sockets, hence it is multithreaded. This is the fastest and safest configuration. To use this, also increase the nr of tcp threads that you have dealing with replication.
* Synchronous means that the thread that executes the request, is also the
thread the replicates the data to the other nodes, and will not return until all
nodes have received the information.
* Asynchronous means that there is a specific 'sender' thread for each cluster node,
so the request thread will queue the replication request into a "smart" queue,
and then return to the client.
The "smart" queue is a queue where when a session is added to the queue, and the same session
already exists in the queue from a previous request, that session will be replaced
in the queue instead of replicating two requests. This almost never happens, unless there is a
large network delay.
-->
<!--
When configuring for clustering, you also add in a valve to catch all the requests
coming in, at the end of the request, the session may or may not be replicated.
A session is replicated if and only if all the conditions are met:
1. useDirtyFlag is true or setAttribute or removeAttribute has been called AND
2. a session exists (has been created)
3. the request is not trapped by the "filter" attribute
The filter attribute is to filter out requests that could not modify the session,
hence we don't replicate the session after the end of this request.
The filter is negative, ie, anything you put in the filter, you mean to filter out,
ie, no replication will be done on requests that match one of the filters.
The filter attribute is delimited by ;, so you can't escape out ; even if you wanted to.
filter=".*\.gif;.*\.js;" means that we will not replicate the session after requests with the URI
ending with .gif and .js are intercepted.
The deployer element can be used to deploy apps cluster wide.
Currently the deployment only deploys/undeploys to working members in the cluster
so no WARs are copied upons startup of a broken node.
The deployer watches a directory (watchDir) for WAR files when watchEnabled="true"
When a new war file is added the war gets deployed to the local instance,
and then deployed to the other instances in the cluster.
When a war file is deleted from the watchDir the war is undeployed locally
and cluster wide

I have set the context path to /tdm in the server.xml file. Should this be placed in context.xml?
My first page in the project is called Homepage.html. To start my project I give http://localhost:5050/tdm/homepage.html
in a browser. Here I accept a username and password from the user and then do the validation in
a valid.jsp file, where I connect to the database and check and use jsp:forward to go to next pages
accordingly. However when I enter the username and password and click Go in the homepage, nothing is
displayed on the next page. The URL in the browser says valid.jsp but a blank screen appears.
WHY DOES IT HAPPEN SO? DOES IT MEAN THAT TOMCAT IS NOT RECOGNIZING JAVA IN MY SYSTEM OR IS IT A PROBLEM
WITH THE DATABASE CONNECTION OR SOMETHING ELSE? I FEEL THAT TOMCAT IS NOT EXECUTING JSP COMMANDS?
IS IT POSSIBLE?WHY WILL THIS HAPPEN?
I set the JAVA_HOME and CATALINA_HOME environment to the jdk and tomcat folders resp.
Is there any other thing that I need to set in classpath? Should I have my project as a
WAR file in the webapps of TOMCAT or just a folder i.e. directory structure will fine? -
Problem with Struts Validation and apache dtd definition.
Jakarta Struts
Java Version 1.5
We have one web application that is being a little problematic, on startup two errors are thrown relating to the same problem (errors below).
We get 401 returned for http://jakarta.apache.org/commons/dtds/validator_1_0.dtd
both the validation.xml and validation-rules.xml have the same doc type set as below:
<!DOCTYPE form-validation PUBLIC
"-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.0//EN"
"http://jakarta.apache.org/commons/dtds/validator_1_0.dtd">
We have the same configuration set for several other web application deployed succesfuly on the same tomcat application server without any problems. I'm not sure why this one application is causing a problem, I don't see any difference between the validation.xml and validation-rules.xml files in this application to any of the others that have been succesfully deployed, infact the validation-rules.xml is identical for all the web applications hosted on this server.
Any ideas appreciated

Hi,
Some time ago I've been working with Apache (3.17 or something) and Tomcat 3.x on a Win98 system. This worked quite well...
Now I have downloaded and installed Apache 3.20 and Tomcat 4.0 on a WinME system. Apache works properly and I can also run the JSP and servlet examples of Tomcat (http://localhost:8080).
However, I cannot access the sample JSP's and servlets when I'm using Apache. That is, if I go to the default index.html of Apache (http://localhost/) I get the page, but http://localhost/examples fails.
I have tried to find information on how to link the Tomcat 4.0 'engine' with Apache 3.20 (I expect having to make changes to the httpd.conf file), but the renewed documentation on the Jakarta-Tomcat pages is total cr*p. I hope someone in these forums can show me an example of how to enable Tomcat 4.0 support in Apache 3.20 webservers...Okay, so far I've found out that MOD_WEBAPP takes care of accessing Tomcat 4.0 from Apache, so that problem is solved.
Suppose I want to add an example JSP of my own to the examples directory. I'm able to put the JSP file in a new subdirectory called "temp" under $CATALINA_HOME/webapps/examples/jsp and it runs.
However, after putting a new feature in my JSP file it crashed. When I put a classfile that is now required under $CATALINA_HOME/webapps/examples/WEB-INF/classes/temp, which is exactly where the Tomcat examples leave their classfiles, Tomcat tells me it cannot find the class. Can someone please show me an example of what I need to type in the server.xml file, a web.xml file and where exactly I'm supposed to put my classfile... -
Tomcat and apache mod_jk or mod_webapp
Hello,I am using linux and I am running a apache web server and I also use tomcat.
I have upgraded from tomcat 4.0 to 4.1.24 and I am now wanting to use servlets and jsp with apache.I have messed around with servlet etc for awhile now but I wish to use them on my server,which is apache.My question is,do you know of a good website that explains how I can use the mod_jk,mod_jk2 or mod_webapp with apache 2.0 so I can use servlet with apache.I have looked but have not came up with nothing good and the stuff I have found is for older version and I am not sure if I need to use the mod_jk ,mod_jk2 or mod_webapp with the version of apache and tomcat I have.Ps,A good tut page on this would be nice.
Thank you for your time.
"Note" the new tomcat is a pain in the %$# to set up cause you have to uncomment the servlet invoker in the conf/xml file.Older version you did not have to do this cause it was already done for you.So this note is for people that has ever had trouble with setting up the new tomcats cause it was a pain in my @$$ figuring out why the hell the servlet was not working.

D.W.A"Note",I cross posted this thread see

Integrating Tomcat and Apache - typo in the instructions??
I'm a total newbie at this, but one line in the "Flashguide" instructions I found on Galatea http://galatea.com/flashguides/home looked wierd to me:
In the instructions for integrating Tomcat 4.0.x to Apache 2.0.x using mod_jk, it states that the mod_jk.so file should go in the APACHE_HOME/libexsec folder.
Then, further on down in section 5 it says that, for Apache 2.0, one should add the line:
"LoadModule jk_module modules/mod_jk.so" to the httpd.conf file.
Shouldn't that be "LoadModule jk_module libexec/mod_jk.so"?? Thats what is says to do for Apache 3.x,
The Galatea instructions otherwise seem pretty succinct and easy to follow.Tomcat 4.0.6 happens to be on the server - and I can't change it (yet). Right now it isn't working in either folder, I am trying to remove this issue as an unknown before looking at other things. Do the math - it'll save about half my time when I try to correct other things.
-
I installed Apache HTTP server and Tomcat, but I cannot run the examples coming with Tomcat. What config should I change, or what should I do? Thanks.
Thanks for all of your help. Now I am using Tomcat only and it works well. Just wondering what is the advantage of using Apache along with Tomcat.Benefit of using Tomcat + Apache
1. For reverse proxy.
For example, your domain name is www.abcd.com.
Now you have program written in PHP and Java.
PHP run under Apache.
Java run under Tomcat.
Here, you can use Apache as PHP server as well as reverse proxy.
Using reverse proxy, you can redirect all incoming request which begin with http://www.abcd.com/servlet/ to Tomcat. Other than that, go to php.
2. Apache is faster for file download.
For example, if your website is a multimedia website. You may think to make your website more responsive. Retrieving picture/sound/html files from Apache is generally faster than Tomcat.
You can put all the pictures in 1 directory (/pictures/). If client request for picture, let apache handle it. But if client request for JSP/Servlet, forward it to Tomcat (reverse proxy).
3. Rewrite Engine
Apache is very powerful with its rewrite engine. You can learn this from apache website. Basically rewrite engine is a request string reconstructor module.
For example:
http://www.mydomain.com/ARTICLE_12341555.HTM
can be reconstructed by apache rewrite into
http://www.mydomain.com/servlet?action=getArticle&varticle_id=12341555&jsp=ShowArticle
As you see, generally people like shorter url.
The advantage of the first url is its spiderability. Generally web crawler (yahoo, hotbot, google) crawl url which is static. The first url looks static, right?

Hi,
Wanted to know regarding the performance difference between apache'Jserv and tomcat.
I'm using apache with Jserv for JSP and i have an search engine application which fetches values from the database and if multiple users are accessing the site at the same time...the JVM goes 100% and the page is not displayed.
I wanted to know that if i switch from Apache and JServ to Apache and Tomcat..will it make any difference performance wise or will it be the same.
Platform: WindowsNT
Backend: Oracle 8i.
Thanks in advance.To my understanfing, JServ was the older jsp container from apache and it is not being developed or maintained anymore. Tomcat is the new apache jsp container and it is activley develped (They release minor version very often).
You can find more info on the tomcat documentation at
