Re: Web Service Deployment
Hi All,
Sorry for the previous question which i asked about web services deployment.
Actually i din't go through the build.xml file, now i got the solution.
thanks,

Hi All,
Facing problem regarding the Environment variables. Couldn't understand

We had similar problems when our application was run on 'Apache 1.3.22+Tomcat3.2.2', but finally after a thorough analysis we found that the problem really was on the 'Connection objects'. Please make sure that the connection objects used in the application is properly returned to the pool after use and is killed when the load on the server goes less.

Oracle JDBC driver must be unpacked?
Hello All, I'm migrating from Tomcat3.3 to Tomcat4.0.3 and having trouble with my oracle connections. With tomcat3.3, I simply put the oracle jar file into WEB-INF/lib.

The only way that the servlet seems to find the driver is if I unpack the jar file into WEB-INF/classes. Can anyone explain what the problem might be? As an aside, I'm not convinced that any classes in WEB-INF/lib are being found.

Re: Oracle JDBC driver must be unpacked?
There are a couple things that could be going on. There are some classloading issues that were introduced in Tomcat-4.0.2 and Tomcat-4.0.3 is a carbon copy of 4.0.2 except for a security fix. One thing you might to is move to Tomcat-4.0.4-b2. The classloading issues have been solved along with a bunch of other bugs. It seems very stable. I'd recommend trying that. Secondly, you might try getting your dirver with: Thread.currentThread().getContextClassLoader().loadClass(MyClass); rather than Class.forName(MyClass); The first way is the proper way to load classes in Java2. Class.forName is the Java1 way and doesn't take into account your classes being loaded by multiple classloaders like the environment of Tomcat. I have run Tomcat-4.0.4-b2 with the Oracle12.jar in both WEB-INF/lib and in $TOMCAT_HOME/lib and in $TOMCAT_HOME/common/lib. I have had no issues so far being able to classload the Oracle driver.

Why deployment using xml file doesn't work?

Re: Apache 2, Tomcat 4 and mod_jk2
On Fri, 26 Apr 2002, Anthony W. Marino wrote: The example for mod_jk2 shows a worker's config for AJP13 but I thought that jk2 is AJP14? Well, there is a lot of confusion ( and I'm talking about those of us who are working on the connector !). We used to call 'ajp13' 3 things: - a wire protocol - an API - an 'worker' There is even more confusion in the term 'worker', but that's a different story. mod_jk(1,2) are all supporting multiple protocols and multiple APIs. By protocol I mean the wire format, how the strings, ints, etc are marshalled and packed. For example we support 'ajp12' - the protocol that is used in mod_jserv, and we support what is called 'ajp13', an extension that is bidirectional and more efficient. There is also JNI - but that's a special case. We also support a couple of 'APIs' - i.e. 'methods' that are called on the server and container ( looking at mod_jk as a basic RPC mechanism ). We call 'ajp13' the API that is normally used with tomcat ( all versions ). We decided ( I hope ) that the protocol is good enough - I can see no major improvement that would justify changing it. If we change, I hope we'll just switch to (subset of ) CDR or XDR (i.e. standard formats) - but that may affect the performance and add unneeded complexity. mod_jk2 will support additional APIs - i.e. things like autoconfiguration, md5-handshaking, etc. The focus so far has been in refactoring the core to make it more flexible and cleanup the configuration - in order to better support the new features without messing the code. If you are interested in more discussions - I would sugest joining tomcat-dev. Mod_jk2 is not yet ready - but it will be ready much sooner with your help :-) Costin Anthony Thanks to Michael Delamere and Pascal Forget, I'm happy to shout out that there's a HOWTO for setting up Apache 2, mod_jk2 and Tomcat on Linux (and therefore probably other UNIX flavours) It's linked from http://www.pubbitch.org/jboss Regards, Simon -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED] -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]

First, I am hoping to slowly deprecate the configuration

What you should configure is channels. The names can be

Example:
channel.socket:localhost:8009
channel.apr:${server_home}/work/unix.socket
channel.jni:
Each channel will be associated with a worker automatically,
using ajp13:localhost:8009, etc.
In addition, now all channels are automatically added to
the default worker ( which is now the 'lb' worker ).
So if you define one or many channels, and set the
worker to lb ( without any other special configuration )
you'll get everything working (I hope ) easier.
Going through the lb has a minimal overhead, but greatly
simplify things and enables many other things.
There is a second change ( not yet implemented, but
high on the list ) in the 'lb' configuration. Instead
of 'workers' we can use 'groups' and 'instances'.
An 'instance' ( the name is not yet clear ) is a VM running
tomcat ( coresponds to the jvmRoute - used for sessions ).
A 'group' is an lb worker forwarding to multiple tomcats.
What I would recommend for configuration is mapping all
webapps to a 'group' ( even if you have a single tomcat
instance ). If you later add more tomcats you'll have
minimal changes ( hopefully - none !).
There are 2 major advanced use cases:
- a pool of tomcats running the same apps. That'll
be the easiest to configure, the default (lb) worker
will just do that.
- different pools of tomcats, each with different
apps. That's where groups can help.
The goal is of course to have the minimal ammount of
work - the worker and lb configuration can be greatly
automated ( we're trying to get each tomcat to
register automatically when it starts with jk ).
What do you think ? The last part is still work in
progress, and all of this would benefit a lot from
your feedback.

Re: Apache 2, Tomcat 4 and mod_jk2
Hi Costin,
I think another point of confusion is what future mod_jk is going to have.
I´ve read a lot about the future of this connector lately and it appears
that a lot of work is taking place right now in order to get mod_jk2 running
stable and to improve the configuration.
On the other hand I´ve also heard that mod_webapp is to play the major role
in the future, possibly replacing mod_jk one day.
I can´t imagine the latter happening because otherwise all the work would be
a waste of time, but could you perhaps share your thoughts on the future of
mod_jk/mod_jk2.
Thanks

Re: Newbie Q: IIS and Tomcat (on a different server) [SOLVED]
Yes, it appears that this is possible (although untested by myself or the author of the following): http://www.jguru.com/faq/view.jsp?EID=497282 Elizabeth Barham [EMAIL PROTECTED] writes: Hi, I'm new to this list, new to Tomcat and new to Java. Please forgive me if this question has been answered before or if it doesn't make much sense. When configuring Apache for UNIX to work with Tomcat, one may use various modules. When setting up mod_webapp, one of the configuration parameters was the host on which tomcat run - localhost. This most likely is a normal thing, to run Tomcat and Apache on the same server. I did a Google search and I did find a document describing how to set up Tomcat to work with IIS *but* I did not see any mention of the server on which Tomcat is running and I imagine that, again, it is inferred that Tomcat is running on the same host as IIS. My question is: Is it possible (now) to run IIS on one server and have it forward servlet, jsp, etc requests to Tomcat *running on a different server*? A company I do work with runs a IIS webserver. I'm not overly fond of ASP or Microsoft and would much rather my own servlets run on a UNIX machine. Is this possible?

Re: Oracle JDBC driver must be unpacked?
Pablo: WEB-INF debe ir capitalizado porque asi lo establecen las especificaciones de servlet para web applications de sun. Un abrazo Bernardo I just move to 4.0.3 too, and in my case (I have windows 2000), I needed to capitalize WEB-INF for tomcat 4 to be able to find my classes. I was wondering if you might have the same problem. Pablo. - Original Message - From: John C Cartwright [EMAIL PROTECTED] To: Tomcat User Mailing List [EMAIL PROTECTED] Sent: Saturday, 27. April 2002 10:35 Subject: Oracle JDBC driver must be unpacked? Hello All, I'm migrating from Tomcat3.3 to Tomcat4.0.3 and having trouble with my oracle connections. With tomcat3.3, I simply put the oracle jar file into WEB-INF/lib. With Tomcat4, this doesn't work, complaining at run-time about driver not found. I've also tried putting the oracle.jar into $CATALINA_HOME/lib and $CATALINA_HOME/common/lib. The only way that the servlet seems to find the driver is if I unpack the jar file into WEB-INF/classes. Can anyone explain what the problem might be? As an aside, I'm not convinced that any classes in WEB-INF/lib are being found. There was another class that the servlet complained could not be found until I moved it jar file from WEB-INF to $CATALINA_HOME/lib.

ApacheJSSI.jar and Tomcat
Hi, I download ApacheJSSI.jar from: http://java.apache.org/jservssi/dist/ And placed it in: TOMCAT_ROOT/server/lib I then updated web.xml: servlet servlet-namejhtml/servlet-name servlet-classorg.apache.servlet.ssi.SSI/servlet-class init-param param-namedebug/param-name param-valueyes/param-value /init-param load-on-startup4/load-on-startup /servlet servlet-mapping servlet-namejhtml/servlet-name url-pattern*.jhtml/url-pattern /servlet-mapping Unfortunatly, though, when I startup Tomcat, I get this error in the log: java.lang.ClassNotFoundException: org.apache.servlet.ssi.SSI Although this is in ApacheJSSI.jar residing in the TOMCAT_ROOT/server/lib directory: 2395 06-22-99 19:20 org/apache/servlet/ssi/SSI.class I have tried renaming ApacheJSSI.jar to servlets-jssi.jar but it still continues to have the problem. I'm interested in using SSI pages that have the servlet tag - jssi. Any ideas on how to remedy this are most welcome!
