RE: New session PER REQUEST
Thanks Maurice. I'll need to look into this. > The one difficulty I have NOT seen is losing the session ID. > I do get session ID persistence where it is permitted (across http page > transitions, across https page transitions, and across http->https page > transition) > > Maurice Yarrow The loss of session is due to a combination of things, namely the fact that I'm using mod_rewrite in order to add to and remove elements from the url and the way that Tomcat binds sessions to a given context. I wanted to filter out the app path information, so in www.abcdomain.com/abc I don't want the user to see the last /abc portion of the url - however Tomcat needs that to bind to the correct application context. I was adding it before the request was sent to Tomcat using mod_rewrite and then removing it on the way back using mod_proxy, however I was losing the session every time. Then I found this thread from this listserv from Feb of this year: http://mail-archives.apache.org/mod_mbox/tomcat-users/200602.mbox/%3C00b301c [EMAIL PROTECTED] It seems others ran into the same issue I did. The work around is setting the attribute emptySessionPath="true" in the element in server.xml. By doing this, the session is no longer tied to the current context based on the url (which I was losing on my rewrites) but instead it seems to be bound to the current default context (that last statement is actually incorrect and oversimplified, but explanation enough for me for now). Because of the way I am using virtual hosts, this works for me. I'm sure this will be a tremendous pain months from now if I need to make changes, but seeing as I have a tight deadline, I'll use this work around for now and hope for the best later.

*ding ding ding*
We have a winner! I removed the rewrite rules from my httpd-vhosts.conf file
and hit my web app that way, and the session is not lost! So I now know the
cause of the problem is my URL rewriting, however this creates another
problem. The client does not want to see urls with an identifier on the end
of them (i.e. www.abcdomain.com/abc), yet I need the identifier to correctly
send the request to the correct container in Tomcat (meaning the abc app
lives under the /abc folder under webapps in Tomcat). So when a request
comes in for www.abcdomain.com I need to forward that request to Tomcat with
an /abc on the end of it so that Tomcat correctly resolves it to the "abc"
application and then when the response is returned to the user the url still
appears as www.abcdomain.com with no /abc identifier after it. (Does this
make sense? I could be doing a bad job of explaining this.) Is there an easy
way to resolve this that I'm not aware of through Apache or Tomcat? Perhaps
using mod_proxy?

RE: New session PER REQUEST
I moved my port to 8081 and I still see the same behavior. *sigh*
I'm still getting no positive results. I'm now thinking this issue involves
one of two things. 1) Mod proxy and the way I've configured it; or 2) the
rewrite rules I do on each request to and from my domain.
This is my first time using mod proxy. I have one instance of Tomcat and one
instance of Apache serving multiple web apps. I need to be able to map any
one app to the correct container in Tomcat in a method that is seamless to
the end user. Using mod rewrite, I append an identifier to the end of each
request for a given domain (i.e. for www.abcdomian.com, I append /abc to the
end, giving me www.abcdomain.com/abc. - if the identifier is not already
present) In my httpd-vhosts.conf file I then map /abc to my Tomcat connector
using mod proxy. When the request is returned from Tomcat, the /abc is
removed from the url by mod proxy so that the user never sees the extra
identifier that was appended. Can this behavior be accomplished with mod
proxy alone (meaning I can remove mod rewrite from the picture completely)?
Could this rewrite be causing me to lose the session between Apache and
Tomcat? Do I have mod proxy configured properly and is *that* what is
causing my problems??

I don't believe I'm setting any of these things. Correct me if I'm wrong,
but the changes that you're talking about need to be configured on the
Apache side? Below I've posted the relevant portion of my httpd-vhosts.conf
file. I've been looking online for a "tutorial" of some kind to show me how
I need to configure this, but I haven't had a lot of luck yet (other than
tutorials that go into clustering and load-balancing... neither of which I
need). Any help in getting this working would be greatly appreciated.
(As you can see, I'm currently playing with getting the pass through
mod_proxy to use sticky_sessions, but this doesn't yet appear to be
working.)

I've actually hard coded the username and password into my code when I've tested *not* using connection pooling, so I know what they are in that case. When using connection pooling the username and password are stored in my context.xml file as attributes in a Resource element. I'm not sure how to get the values of those attributes in my code to print them out. Also, if I were more knowledgeable in Oracle, I'd love to check to the database to verify the pool is being created, and possible to see if what credentials are being used on the Oracle side when I attempt to connect through the connection pool, but I'm not sure where to look to find that information. I've looked at various logs on the db server, but none of them seem to contain the information I'm looking for, so I'm sort of lost there. -D - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Yes, using that username and password works fine through SQL Plus, and I've
connected to the database several times through SQL Plus using those
credentials. In fact connecting to the database through my code works fine
if I don't use connection pooling! In my test java class I've tried
connecting to the DB using connection pooling, and not using connection
pooling.
This way works fine with no errors:
Connection conn;
Driver driver;
String driverUsed = "oracle.jdbc.OracleDriver";
String serverAddress = "jdbc:oracle:thin:@devdb1.utrs.com:1521:flcdb";
try {
driver = (Driver)Class.forName(driverUsed).newInstance();
conn = DriverManager.getConnection(serverAddress, "myuser",
"mypass");
}
catch (Exception e) {
log.debug("Connection to database failed!", e);
}
This way fails with "invalid username/password" error:
DataSource ds = null;
String dsName = "jdbc/flc";
try {
Context initContext = new InitialContext();
Context envContext = (Context)initContext.lookup("java:/comp/env");
ds = (DataSource)envContext.lookup(dsName);
if (log.isDebugEnabled()) {
log.debug("(exeucte) Retrieving database connection from the
DataSource.");
}
conn = ds.getConnection();
if (log.isDebugEnabled()) {
log.debug("(exeucte) Connected.");
}

RE: Database connection pooling in Tomcat 5.5
More progress with this issue. It seems that on our development server (solaris box running solaris 10) the connection pool connects properly. However on my local box (a Windows XP SP2 box where I'm doing my development before I move it to dev) the connection pool returns to me an "invalid username/password" error. Both environments are using exactly the same web.xml, context.xml, database credentials, etc. In fact I used the same war file compiled from my local box to get the initial version of the code up on our dev box. Obviously it's a configuration issue - but where? Why does it work on the dev server and not on my local box??

Great - not only is the connection pool not working locally, but the drivers cannot be loaded in my production environment. I've packaged ojdbc14.jar into my war and it deploys into my WEB-INF/lib directory. When Tomcat 5.5 starts up and I point a browser at my application, I get a "Cannot load JDBC driver class 'oracle.jdbc.OracleDriver'" error. I thought this should be automatic. My connection pool (as seen from my connection pool thread) references the oracle.jdbc.OracleDriver and the driver seems to reside in the ojdbc.jar file AND that jar lives in my WEB-INF/lib folder on my server under my deployed app. Where am I going wrong??

Database connection pooling in Tomcat 5.5
Hi all. I'm attempting to set up database connection pool using Tomcat 5.5 and Oracle 10g. I've been following the "JNDI How To" guide from Apache (http://tomcat.apache.org/tomcat-5.5-doc/jndi-datasource-examples-howto.html ). My question is - where should I define the connection pool resource? Meaning, where should my "Resource" element appear. I've read two different descriptions about how this should be done in the Apache documentation. The first description (from the above link) states that I should modify server.xml and add a new Context element as such and in that new context define my resource for my connection pool. However, if you read the "Context" documentation linked to the above How-To (located at this link: http://tomcat.apache.org/tomcat-5.5-doc/config/context.html) you'll find in there the following text - "Please note that for tomcat 5, unlike tomcat 4.x, it is NOT recommended to place elements directly in the server.xml file. Instead, put them in the META-INF/context.xml directory of your WAR file or the conf directory". So I'm wondering if I should modify server.xml or create a context.xml file. Currently I'm trying the context.xml file route, but it is not working (although this could be because I'm configuring things incorrectly). Can anyone point me in the right direction here? Thanks, Darren

connection pooling question (posted correctly)
Hi all. I'm using Oracle 10g with Tomcat 5.5 and Struts 1.2.9. I'd like to set up connection pooling for my application. I've read the Tomcat "HOW-TO" on setting up a JNDI Datasource for connection pooling, but one thing confuses me - In the how-to, it states "Configure the JNDI DataSource in Tomcat by adding a declaration for your resource to $CATALINA_HOME/conf/server.xml. Add this in between the tag of the examples context and the tag closing the localhost definition. If there is no such tag, you can add one as illustrated in the Context and Host configuration references..." However, in "The Context Container" documentation referenced in the above article it states "Please note that for tomcat 5, unlike tomcat 4.x, it is NOT recommended to place elements directly in the server.xml file. Instead, put them in the META-INF/context.xml directory of your WAR file or the conf directory" So where do I place this element containing my resource that describes the datasource? Thanks, Darren
simple connection pooling
Hi all. I'm using Oracle 10g with Tomcat 5.5 and Struts 1.2.9. I'd like to set up connection pooling for my application. I've read the Tomcat "HOW-TO" on setting up a JNDI Datasource for connection pooling, but one thing confuses me - In the how-to, it states "Configure the JNDI DataSource in Tomcat by adding a declaration for your resource to $CATALINA_HOME/conf/server.xml. Add this in between the tag of the examples context and the tag closing the localhost definition. If there is no such tag, you can add one as illustrated in the Context and Host configuration references..."

Instead, put them in the META-INF/context.xml directory of your WAR file or the conf directory" So where do I place this element containing my resource that describes the datasource? Also, if the datasource is set up through Tomcat - is it then visible in Struts? I'd imagine in would be through the JNDI, but I want to make sure it's not in some "other context" that struts can't see.

*sigh* Apologies to the group. There is no need to respond to my posts. I knew it had to be something easy that I was overlooking.

When I attempt to go to the above URL I get the error "The requested resource (/abc/abc) is not available." What am I doing wrong here?

The requested resource is not available
Simple problem (hopefully) and I've been here before, but for some reason I can't find my way through this error. Here's the scenario: I've written a servlet which I'm deploying in Tomcat 5.5 using Apache 2.2 as the web server. The servlet is a controller for one domain I have on my server (lets call it the 'abc' domain.) The servlet is bundled into a war file and deploys into Tomcat with no errors. The servlet-mapping in the web.xml file defines the following: controller com.abc.framework.controller.ControlServlet controller /abc I've configured my httpd-vhosts.conf file to do a proxy pass through as follows: DocumentRoot /work/abc/abc-app/deploy/var/www/htdocs/abc ServerName www.abc.com ServerPath /abc ErrorLog logs/abc/www.abc.com-error_log CustomLog logs/abc/www.abc.org-access_log common ProxyRequests Off ProxyPass / http://localhost:8080/abc ProxyPassreverse / http://localhost:8080/abc When I point my browser at http://www.abc.com/, I get a Tomcat error "The requested resource (/abc) is not available." This indicates to me that the proxy pass through is working properly in Apache, but that Tomcat is not handing off the request to my serlvet. Also I've tried hitting the servlet directly by pointing my browser to http://localhost:8080/abc and I get the same "The requested resource (/abc) is not available" error. What have I done wrong? Everything looks good to me... Thanks for the help.

Default install of Tomcat not working properly
I'm having a problem getting tomcat 5.5.17 running on Solaris 10. I preformed a default install of all the binary files and set my JAVA_HOME variable to my install of jdk1.5 (/opt/jdk1.5/) The problem I am running into is when I try to view my servlets-examples page I get a 404 error from tomcat saying it can't find the resource. When I click on the JSP examples the page appears but none of my JSP examples function properly.

RE: mod_jk weirdness
Chris, Not sure if this is helpful but it appears the next step that is failing is the actual connection to tomcat from apache (unless you've left this part of your mod_jk.log out of your post). Here's the mod_jk.log output of a test I did on my local machine. The first worker 'testworker' connects successfully; while the second 'newworker' fails at about the same point you appear to be failing. In the below case, 'newworker' fails because it can't resolve the tomcat address after it sets the contact for 'newworker'. Don't know if this helps or not...

You are correct. I realized this yesterday while playing with this problem.
I've since removed my servlet.xml file that contains the tag
specifying the docBase and path.
I've gotten over this hurdle and immediately gotten hung up on the next one.
=P The only file I'm using for mapping the servlet now is the web.xml file
in the ${catalina.home}/webapps/servlet/WEB-INF directory.
The new issue is "ClassDefNotFound" that occurs when I point my browser at
the servlet (see last message, because I'm not retyping that 'brief' recap
again).
Thanks, though. I do appreciate the help.

RE: (newb) Tomcat servlet mapping problem
As an add-on - I successfully mapped the Tomcat servlet example "HelloWorldServlet" to my /servlet directory successfully through my web.xml file. I did this to make sure that a servlet with no package could be deployed the way I am attempting (HelloWorldExample has no package). The ONLY error I encountered while deploying the HelloWorldExample, was it complained that the ResourceBundle the code was looking for couldn't be found. I recompiled the servlet without the ResourceBundle code and the servlet worked correctly. (I wasn't sure how to configure the ResourceBundle in the code. I copied all the files the resource bundle seemed to be referring to into my /servlet directory along with the compiled HelloWorldServlet code, but it still complained on execution that it couldn't locate the resource, so it was easier for me to comment it out.) This tells me I can definitely deploy a servlet the way I am trying to, but it also raises questions about why the resource bundle couldn't be located.

I have. The servlets I am trying to deploy (err, map?) do not have a package
associated with them. My class files live in the
${catalina.home}/webapps/servlet/WEB-INF/classes directory.
My ${catalina.home}/webapps/servlet/WEB-INF/web.xml looks like this (minus
the xml identifier and DOCTYPE tags at the top) -

I had not, but that was an excellent idea (kinda upset I didn't think of
that one myself =P).
I get the same error when trying to execute the servlet directly through
Tomcat. The same information is repeated in the log files. Unfortunately, I
don't have great logging (I may have it configured wrong - everything goes
to localhost.log and catalina.log, nothing goes to stdout.log or stderr.log
at all) so it makes fixing this problem that much more fun/challenging!

Have you tried accessing the servlet directly via tomcat yet?
If going through tomcat itself gives an error then work on fixing that error
first before worrying
about mod_jk.

It looks like the classloader was unable to find my servlet, but since the class lives in the webapps/servlet/WEB-INF/classes directory, I thought it was included in the classpath of the app server (or more specifically, my applications classpath) by default. Is this not correct? And, if it's not correct... where do I specify the classpath for the classloader for this app? (Please forgive my Tomcat classloading ignorance.)

RE: (newb) Tomcat servlet mapping problem
Thanks for your help Warren.
I think I've made some progress on this problem, but I've encountered
another error. Here's where I am now...
I commented out all references to JK2 and downloaded
mod_jk-apache-2.0.55.so. I've set up mod_jk in apache's httpd.conf, and I am
now connecting to Tomcat successfully that way (example servlets have been
mapped successfully).
It looks like my original problem was caused by a simple mapping error. My
httpd.conf file now has a tag that forwards all requests for
'/servlet', as such
# Send servlet for context /servlet to 'worker1'
JkMount worker1
Under webapps, I've created a 'servlet' directory, and my
webapps/servlet/WEB-INF/web.xml file looks like this (note, I removed the
'/servlet' from the url-pattern, and this fixed my 'resource not found'
issue) -
http://java.sun.com/dtd/web-app_2_3.dtd";>
FLCUpEvDisplayServlet
FLCUpEvDisplayServlet
FLCUpEvDisplayServlet
/FLCUpEvDisplayServlet
So, I've made some progress (I think), but now I'm getting a new error -
2006-01-22 19:21:01 StandardWrapperValve[FLCUpEvDisplayServlet]: Allocate
exception for servlet FLCUpEvDisplayServlet
javax.servlet.ServletException: Wrapper cannot find servlet class
FLCUpEvDisplayServlet or a class it depends on
So did I hit my servlet, or did the classloader fail to locate it??
Thanks.

Darren,
I'm pretty new to this as well. Here are a couple of things I do know.
mod_jk2 is deprecated. That doesn't mean it won't work but all development
effort has been re-focusted to mod_jk. It's simple enough to download and
build.
1) Is your servlet in a package (us.souther.simple)? Did it compile
without error?
2) Generally the directory tree for servlets in packages =
WEB-INF/classes/us/souther/simple (which is where your web.xml is telling
tomcat to look for the class file).
3) Double-check the path entry in your context tag. I moved from tomcat 4
to tomcat 5.5, skipping the 5.0 releases so I can't provide any insight on
the context directives (in 5.5 you don't specify a context path). Just make
sure it's pointing tomcat to something real.
4) Some good resources are Jayson Falkner & Kevin Jones book "Servlets and
JSP The J2EE Web Tier", this mailing list, and Google.
Hope this helps.

(newb) Tomcat servlet mapping problem
I'm running Tomcat 5.0.30 and Apache 2.0 (both are running fine and without
errors).
I've connected them using mod_jk2, and I can see that apache is correctly
forwarding URLs specified in the workers2.properties file correctly.
I am now attempting to map a test servlet called "SimpleServlet" to an URL.
I've deployed the servlet in the directory "SimpleServlet". In the
webapps/SimpleServlet/WEB-INF directory I've added the following web.xml
file:
http://java.sun.com/xml/ns/j2ee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd";
version="2.4">
SimpleServlet
us.souther.simple.SimpleServlet
SimpleServlet
/simple-servlet
In the ${catalina.home}/conf/Catalina/localhost directory, I've added the
following SimpleServlet.xml file:
In the workers2.properties file (on the Apache side), I've added the
following entry:
[uri:localhost/simple-servlet/*]
worker=ajp13:localhost:8009
debug=99
When I try to hit the URL http://localhost/simple-servlet I get back this
response from Tomcat:
HTTP Status 404 -/simple-servlet
type Status report
message /simple-servlet
description The requested resource (/simple-servlet) is not available.
Apache Tomcat / 5.0.30
Can anyone please tell me why my servlet is not mapped to the URL properly?
Thanks.
Darren
