Re: Use of return statement in servlet.
Thanks for the reply I want the browser to point to the query page if user did not provide enough data or an error happens like database connection is not available. I want user to re enter data or wait for some time . So I dont want to use requestDispatcher.forward() method or redirect to an error page. I want to know is there any problems in using the return statement in servlets/jsp.

For this can I use a return statement in the beginning of a servlet. Will it cause any state problems. I dont like putting the code in an if block. There will be lots of if blocks. A servlet is a web application component. It is invoked when a web client makes a request. The client expects SOMETHING as a response from the server and, thus, from the servlet. So, quitting with no response is not a good practice. What you should do is display an error page. There are several ways you can do it, requestDispatcher.forward() or throw an exception and have custom error pages ready.

RE: Opinions
-Message d'origine- De : Robert Charbonneau [mailto:[EMAIL PROTECTED] Envoyé : vendredi 31 octobre 2003 06:17 À : Tomcat Users Mailing List Objet : Opinions Does anyone have an opinion of Tomcat running in a very high traffic environment, let's say, 100K - 500K unique visits/day? I'm also wondering about the possibility of running a Tomcat server standalone as opposed to using mod_jk.so with Apache to mount webapps with. Would this be more stable, and is there any loss to me if I *don't* use Apache? I have several tomcat standalone applications with more than one connection per second. It works well. I had to be carefull with: o JITC bug in IBM 1.4.1 Jvm on hyperthreaded machines (SIG11) o Silly name lookup at IBM Jvm startup (it needs to know the name for all the interfaces up on the machine or it SIG11. Even if your tomcat has nothing to do with the interfaces, event if you need administrative unnamed (DNS, Hosts) interfaces). This does not happen with Sun Jvm. o Memory leaks (in java servlets or Jvm or both) o Tomcat 4.1.27 bug when running at the MaxConnector limit (workaroundable) Those applications are wap and web applications, mainly. Total traffic is about 30Mb/s (up to 40) all day. I am in the process of migrating to a LinuxVirtualServer architecture for load balancing and failover. It works well. I have to say that tomcat is not so easy to share between nodes. I had to do at least one modification to catalina.sh (introducing a CATALINA_LOGS). The CATALINA_BASE is shared netween nodes (via NFS) and I need one catalina.out for each node. So... Oh, and last but not least, I didn't find a privilege separation method in tomcat (like in apache or ssh or postfix, or...). Perhaps am I wrong, but, if you want tomcat to run in unpriviledge environment, you have to make it bind to a public port (say 8080). I use iptables to redirect connections from 80 to 8080: If you have only one tomcat running on the server, you can use: /sbin/iptables -t nat -A PREROUTING -i lo -p tcp --dport 80 -j REDIRECT --to-ports 8080 For more than one (one IP for one tomcat is required), you have to deal with DNAT: /sbin/iptables -t nat -A PREROUTING -d 1.2.3.4 -p tcp -m tcp --dport 80 -j DNAT --to-destination 1.2.3.4:8080 This way, you don't have to put any port number in URLs. Ho. I just see that it is all linux related... I don't have any experience in Windows. Sorry. In fact, with a minimal of Unix/Linux sysadmin knowledge, tomcat become spretty scalable.

Problem with JNDI Datasource HOW-TO MySQL Example
I'm new to Java but have installed Tomcat a couple of times, and am now
trying to configure a JNDI datasource (to use with the OpenReports database

I've edited the conf/server.xml and webapps/DBTest/WEB-INF/web.xml files as
indicated in the HOW-TO. When deploying the code in this sample webapp with
Tomcat 4.1.27, I either get a 404 or an error that includes the following:

The above error occurs if the jsp file and class file are in the
$CATALINA_HOME/webapps/DBTest directory together. If I put the compiled
class file (DBTest.class) in webapps/DBTest/WEB-INF/classes, I get a 404

It's a little thin, but what there is is at http://jakarta.apache.org/commons/daemon/ Hu! It's in early developments or is it suitable for production ? And, in a sysadmin point of view, what does that means: There two ways to use jsvc: via a Class that implements the Daemon interface or via calling a Class that have the required methods. For example Tomcat-4.1.x uses the Daemon interface and Tomcat-5.0.x provide a Class whose methods are called by jsvc directly.? The applications are located in CATALINA_BASE directory, I have a conf file with servers and connectors definitions. What should I do to use jsvc? As you said, it's a little thin. I feel that there is a lot of solutions to my problems, but... You can do Apache administration without knowing C or PHP or perl. But you can't do tomcat administration without knowing java. I feel it a week point of Jakarta (perhaps am I wrong, it's just a feeling). Anyway, I will switch to jsvc later. Sorry :).

Re: Problem with JNDI Datasource HOW-TO MySQL Example
Excellent! That worked on the first try, and it turns out that the test JNDI
datasource also works.
It's strange that the need to put class files in a directory of their
package name isn't mentioned in the O'Reilly Tomcat book (diagram on p. 71
shows class file in the WEB-INF/classes directory). Or maybe only some class
files need to be in a package subdirectory?
In any case, thanks much for the help!

Re: xhtml and Internet Explorer
Marius, I think such a feature request should not be addressed to Tomcat, but to the JSP specification itself. Remember that Tomcat is being used as the reference implementation of servlet/JSP technologies, and so it should stick to the specification. Basically, as I see it, your request means a special treatment for a subset of directives in a few specific cases. I think it would imply that tags could be marked as not generating any output, so when in a single JSP line there were only such marked tags and leading / trailing spaces among them, the line itself could be omited from the output. Such a change should be made from the specification. Regards, Rodrigo Marius Scurtescu wrote: JSP is a templating language which is using a meta language: the JSP constructs. The new line is in the JSP indeed, but is it part of the meta language or part of the literal output? I would argue that these new lines are part of the meta language and that they should not be output. You put them there so the meta language you use is readable. See how FreeMarker, another templating language, is dealing with this issue: http://freemarker.sourceforge.net/docs/dgui_misc_whitespace.html#dgui_misc_whitespace_stripping You are not asking the directive to scan anything, the page compiler could consider white space and newlines after a directive as part of that directive.

Re: Use of return statement in servlet.
Anthony, putting a return in a servlet code will not create any state problem for the servlet itself. You could have problems if you have opened resources that need finalization or closing before returning, for example DB connections, or opened streams others than the servlet input and ouput ones, but that depends on the code, and it is independent from the servlet engine. Of course, if you do not redirect to anywhere, or display nothing, what you will get in the browser is a neat clean blank page ;-) I am not sure at all, but I think JSPs could be different, depending on the compiler implementation. I think Jasper generated code does not have problems with return statements, but I check it with every new release I download, just in the case ;-) What I do is to create a simplest JSP: !-- JSP beginning -- Hello World !-- JSP end -- And compile it. Then, looking at the generated servlet code, I check that no resource-freeing operations are done after writing Hello Worl to the output stream.

Re: Opinions
Hi It's a little thin, but what there is is at http://jakarta.apache.org/commons/daemon/ You can do Apache administration without knowing C or PHP or perl. But you can't do tomcat administration without knowing java. I feel it a week point of Jakarta (perhaps am I wrong, it's just a feeling). but you can do tomcat administration without knowing bash and vi , if you use the manager admin interfaces. yes, you lack quite some features if you stick to those. but just imagine the features you lack by not knowing java. I don't think anyone will dare to rewrite the C code of apache to change its behaviour. I feel it's a week point of apache :-) it's a choice. I think historically tomcat was developed to give some backbone to programmers writing applications build on the HttpServlet interface. As a plain webserver, you still need a programmer to set it up correctly, but a monkey can manage it once it's running. whatever, *-pike = Microsoft: HOWTO: Read the Fucking Manual This article demonstrates how to read the fucking manual http://radio.weblogs.com/0001263/junk/Q209354%20-%20HOWTO.html - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Opinions
Also, depending on the amout of static content in your webapps, having an Apache as the front-end can perform better than a standalone tomcat. But this depends on numbers you have to get by yourself. Experimenting uses to be the best way ;-) Rodrigo Vincent Aumont wrote: François, Oh, and last but not least, I didn't find a privilege separation method in tomcat (like in apache or ssh or postfix, or...). Perhaps am I wrong, but, if you want tomcat to run in unpriviledge environment, you have to make it bind to a public port (say 8080). I use iptables to redirect connections from 80 to 8080: No, you're right. You can make Apache listen on port 80 while running as root because it'll change the process' ownership when it opens a new connection. There is no portable way of doing this in Java; therefore, you have to run Tomcat as root if you want to make it listen on port 80. Of course, that's a major security hole. I always front-end TC with Apache and use mod_proxy to achieve what you're doing with iptables. -Vincent. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

It's strange that the need to put class files in a directory of their

Subject: Problem with JNDI Datasource HOW-TO MySQL Example
I'm new to Java but have installed Tomcat a couple of times, and am
now
trying to configure a JNDI datasource (to use with the OpenReports
database
reporting package - see http://sourceforge.net/projects/oreports for
info
on
that).
Before configuring a datasource for db reporting, I'm trying to set up
the
test datasource described on the JNDI Datasource HOW-TO at
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-how
to.html, under the section MySQL DBCP Example.
I've edited the conf/server.xml and webapps/DBTest/WEB-INF/web.xml
files
as
indicated in the HOW-TO. When deploying the code in this sample webapp
with
Tomcat 4.1.27, I either get a 404 or an error that includes the
following:
An error occurred at line: 6 in the jsp file: /test.jsp
Generated servlet error:

/home/ddegraff/packages/openreports-tomcat/work/Standalone/localhost/DBTest/
test_jsp.java:48: package foo does not exist
foo.DBTest tst = new foo.DBTest();
The above error occurs if the jsp file and class file are in the
$CATALINA_HOME/webapps/DBTest directory together. If I put the
compiled
class file (DBTest.class) in webapps/DBTest/WEB-INF/classes, I get a
404
when trying to access the jsp.
The jsp file and class file source is copied below. Any insight would
be
much appreciated.

Re: jk or jk2
Dean- thanks for sharing your material on your tested setup here. I wonder if you've got a distinct idea of how the syntax workers2.properties works. This is actually my single most pressing problem. There is this section like thing: [foo:bar] What does it mean? Is it a [type:instance] - eg. [uri:/context/*] scheme, perhaps? This might make sense. Then this [type:] - eg. [config:] could be a class or singleton-like thing. And then, the properties. Do they always refer to the preceding square-bracketed item? [type:obj] property1=value1 property2=value2 What is the group syntax like? Is a group something I define with the [lb:some_lb_name] statement? Do I need a shared memory file under all circumstances, or is it neccessary only when I have several tomcats? -Florian Dean Searle wrote: The Oreilly book is only for Tomcat and Tomcat as a Standalone web/application server.

RE: Java/JSP/Servlet Programmer
I personally do not care much if the person I interview knows about such or such latest api. Rejecting a person because he/she gets stuck on a technical question is no relevant. You have to look at learning, abstraction, adaptation, communication abilities. You have probably already rejected great potential contributors. Hiring someone just because of a particular technical knowledge is asking for troubles. Once I had a developer who knew Java much better than anybody else in the team. The problem is that he could not understand where we wanted to go because he was just looking at the technology. His contributions ended up being less than the not-so-skilled java developers. Another time I gave the chance to a young guy out of high school. He knew about nothing about programming languages but he strucked me as a problem solver. After one month in the team he knew more that the senior developers about the project and even if he did not know about the lastest tech issues, he solved the different problems you have in daily IT work in a more efficient manner. Finally, even though I use JSP, I have the tendency of building frameworks asap to focus on real business issues. I will probably fail your tests although I built a framework on top of Tomcat to help my web developer focus on the customer issues. Of course, if you are trying to build technology such as a JSP and/or a J2EE, you do need deeper tech knowledge. Still I will argue that solving problems is more important than narrow tech knowledge.

Debug Help with Apache Tomcat, on WinXP
Hey All I have both Apache 2.047 and Tomcat 4.1.27 configured on my XP machine as a localhost service using jk2 configs. I followed the directions on the following page: http://www.greenfieldresearch.ca/technical/jk2_config.html The two services work individually, all configs are done, but the two servers just don't tie together. My thought is that there is a problem with the way I put together the shm file. In my error.log, Apache is crapping on the shm.create() call: [Thu Oct 30 20:17:38 2003] [error] shm.init(): No file But the file is there, I'm not sure how to make it readable/writable to the service if that's the problem. Any help someone could give would be greatly appreciated, THANKS! Below here are my configs: My jk2.properties on Tomcat is a single line: #Shared memory directive shm.file=c:/Apache/Apache2/logs/jk2.shm My workers2.properties with Apache looks like the following: - #define the shared memory file [shm] file=c:/Apache/Apache2/logs/jk2.shm size=100 # Define the communication channel [channel.socket:localhost:8009] port=8009 #host=127.0.0.1 tomcatId=localhost:8009 debug=1 [ajp13:localhost:8009] channel=channel.socket:localhost:8009 # Map the Tomcat examples webapp to the Web server uri space [uri:/examples/*] info=C:/Apache/Tomcat/webapps/examples/ [uri:/servlet/*] info=C:/Apache/Tomcat/webapps/ [status:status] info=Status worker, displays runtime information channel=channel.socket:localhost:8009 [uri:/jkstatus/*] info=Display status information and checks the config file for changes. group=status: worker=status:status [uri:/status/*] worker=status:localhost:8009 group=status: For reference, I uploaded the bigger docs: servers.xml: http://torgler.net/docs/server.xml workers2.properties: http://torgler.net/docs/workers2.properties httpd.conf: http://torgler.net/docs/httpd.conf Also, not sure if these would help or not, the stderr.log outs from the Tomcat startup, which looked fine to me Created catalinaLoader in: C:\Apache\Tomcat\server\lib Oct 30, 2003 8:17:32 PM org.apache.commons.modeler.Registry loadRegistry INFO: Loading registry information Oct 30, 2003 8:17:32 PM org.apache.commons.modeler.Registry getRegistry INFO: Creating new Registry instance Oct 30, 2003 8:17:33 PM org.apache.commons.modeler.Registry getServer INFO: Creating MBeanServer Oct 30, 2003 8:17:35 PM org.apache.coyote.http11.Http11Protocol init INFO: Initializing Coyote HTTP/1.1 on port 8009 Oct 30, 2003 8:17:39 PM org.apache.struts.util.PropertyMessageResources lt;initgt; INFO: Initializing, config='org.apache.struts.util.LocalStrings', returnNull=true Oct 30, 2003 8:17:39 PM org.apache.struts.util.PropertyMessageResources lt;initgt; INFO: Initializing, config='org.apache.struts.action.ActionResources', returnNull=true Oct 30, 2003 8:17:40 PM org.apache.struts.util.PropertyMessageResources lt;initgt; INFO: Initializing, config='org.apache.webapp.admin.ApplicationResources', returnNull=true Oct 30, 2003 8:17:45 PM org.apache.coyote.http11.Http11Protocol start INFO: Starting Coyote HTTP/1.1 on port 8009/font/p - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Edson Alves Pereira wrote: Hello folks, i´m trying to store a database connection in a session attribute or request attribute, but i must choose a name that just one thread per time would knowns. Any idea? If you put the attribute in your request, the name does not matter: only forwarded or included servlets / JSPs will have access to the object, even if the same name is always used. If you want each request to use a different instance of an object, request attributes are the correct place. Session attributes are best fitted for instances that must be shared among multiple requests from the same user (well, exactly from the same user session ;-). Anyway, consider also to execute your DB queries internally and put as attribute the results instead of the connection. It is usually better :-) Regards, Edson - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I apologize for the repost, but I need to solve this problem pretty quickly, and I worry that with the volume on this list, anything unanswered for two days is lost. This is a question that I can't find the answer to anywhere: If I add a certifcate to my keystore, will Tomcat see it immediately (or soon) or do I have to bounce Tomcat to get it to reload it's internal keystore instance? If I have to bounce Tomcat, is there any programmatic way to make Tomcat reload its keystore or a way for some external program to tell it to bounce itself?

Howdy, Hu! It's in early developments or is it suitable for production ? It's ready for production. People are already using it in production with tomcat 5. Of course, I'm biased ;) And, in a sysadmin point of view, what does that means: There two ways to use jsvc: via a Class that implements the Daemon interface or via calling a Class that have the required methods. For example Tomcat-4.1.x uses the Daemon interface and Tomcat-5.0.x provide a Class whose methods are called by jsvc directly.? It's a Developer, rather than Sysadmin, option. Chances are you won't need to worry about it as you'll use commons-daemon with tomcat, which already does the required jsvc invocation for you.

instanceof drives me nuts!
Hi folks,
It may be an off topic question but such weird things occurs in my tomcat
project that posting here is my last chance...
I took over a project for global authentication in my company extending
standard tomcat authentication mecanism (extending AuthenticatorBase).
As I didn't build the project, I am not so familiar with it and I couldn't
avoid to put some of the classes in several places (server, common,
shared, WEB-INF of my apps).
Because I had to face the well known 'NoClassDefFoundError' thrown at
tomcat startup.
I have in my code something like :
Callback callback = getTheCallBackObject();
if(callback instanceof ApplicationCallback) {
((ApplicationCallback) callback).doSomething();
}
When I debug this part, the expression 'callback instanceof
ApplicationCallback' is true, nevertheless if I step once, the code in the
if block is not executed !!!
I tried to replace the test by :
if(callback.getClass().getName().equals(ApplicationCallback.class.getName()))
{
((ApplicationCallback) callback).doSomething();
}
then the code in the if block is executed but I throws a
ClassCastException !!!
I am not sure but I think that might be related to the fact that same
class files are located in different directories of tomcat ?.
Has anybody experienced this kind of weird behaviour?
Any suggestion to understand what is really going on is welcome!
Thanks,
Thomas

Well, I'd LOVE to try to use jsvc and make the appropriate documentation for it, I just CAN'T see where I should declare them, use them, and so on. I suppose it replaces Coyote Connectors, and I should try to define the jsvc classes there (in server.xml), but, it is really to thin for me to start a test. Well, it's Friday, I will sleep on it on two or three nights and try to understand it :). François. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

shared, WEB-INF of my apps).
Don't do this, as it can lead to unpredictable classloading errors.
Keep everything you can in WEB-INF/lib, the rest in common/lib, but no
jar should be in both places. And you probably don't need to put
anything at all of yours in the server classloader directories.
Callback callback = getTheCallBackObject();
if(callback instanceof ApplicationCallback) {
((ApplicationCallback) callback).doSomething();

ApplicationCallback' is true, nevertheless if I step once, the code in

If the doSomething is not executed, how do you know if clause evaluates
to true? From the debugger I suppose?
You can also try the other way around,
callback.getClass().isAssignableFrom(ApplicationCallback.class), to see
what would happen.
Has anybody experienced this kind of weird behaviour?
Strange. I think I've had that happen once or twice, but I can't recall
the solution ;(

RE: Opinions
Howdy, Well, I'd LOVE to try to use jsvc and make the appropriate documentation for it, I just CAN'T see where I should declare them, use them, and so on. I suppose it replaces Coyote Connectors, and I should try to define the jsvc classes there (in server.xml), but, it is really to thin for me to start a test. Well, it's Friday, I will sleep on it on two or three nights and try to understand it :). JSVC does not replace Coyote connectors. It is merely an invocation mechanism for another class. I assume you've read the JSVC page at http://jakarta.apache.org/commons/daemon/jsvc.html. I also assume you've downloaded, installed tomcat5 (5.0.14 preferably), so you can see how jsvc is used there. What, beyond the above information, would you find most useful in understanding jsvc?

Re: instanceof drives me nuts!
Thomas, As I didn't build the project, I am not so familiar with it and I couldn't avoid to put some of the classes in several places (server, common, shared, WEB-INF of my apps). Don't do this, as it can lead to unpredictable classloading errors. Keep everything you can in WEB-INF/lib, the rest in common/lib, but no jar should be in both places. And you probably don't need to put anything at all of yours in the server classloader directories. I couldn't agree more. If possible, try and change the configuration so that you have fewer application dependencies in the server/lib and common/lib directories. If the doSomething is not executed, how do you know if clause evaluates to true? From the debugger I suppose? You can also try the other way around, callback.getClass().isAssignableFrom(ApplicationCallback.class), to see what would happen. Has anybody experienced this kind of weird behaviour? Strange. I think I've had that happen once or twice, but I can't recall the solution ;( Don't forget that (object instanceof MyClass) only works when: - The object actually inherits from MyClass and - object.getClass() was loaded by the same classloader as MyClass Remember that the same class can be loaded twice by different class loaders. The instances they create are not assignable (d'oh)! This is why ClassLoading issues are so hairy. -chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: instanceof drives me nuts!
This is definitely due to the class being loaded twice in two different
classloaders.
An object's type is in fact not only its class name, but a combination
of its class name and the class loader from which the class was loaded.
Note that class loaders can be heirarchical, but if classloader A
delegates the loading of a class to classloader B, the class is
considered loaded from classloader B.
Now, the classloader chosen when you refer to a class by name is the
class loader of the current class. So in
class Bar
{
public void someFunction (Object obj)
{
if (obj instanceof FooClass)
{
...
}
}
}
we are comparing obj.getClass () to Bar.class.getClassLoader
().loadClass (FooClass).
If obj was an instance of FooClass instantiated using the class
definition from a different classloader, then this won't work.
The reason for this kind of behavior is that you can load two different
versions of the same class for example (or two completely different
classes of the same name) within two different classloaders without them
conflicting. Also, static variables are specific only to the actual
class instance, therefore if the same class has been loaded in two
different classloaders, each one will have its own instances of static
members.
That's why, for example, two different web apps can be loaded into
tomcat with different versions of the same library and not conflict.
Now you understand why it's evil to keep your jars in two places.
Cheers,
Erik

Keep everything you can in WEB-INF/lib, the rest in common/lib, but no

I had to be carefull with: o JITC bug in IBM 1.4.1 Jvm on hyperthreaded machines (SIG11) o Silly name lookup at IBM Jvm startup (it needs to know the name for all the interfaces up on the machine or it SIG11. Even if your tomcat has nothing to do with the interfaces, event if you need administrative unnamed (DNS, Hosts) interfaces). This does not happen with Sun Jvm. o Memory leaks (in java servlets or Jvm or both) o Tomcat 4.1.27 bug when running at the MaxConnector limit (workaroundable) Those applications are wap and web applications, mainly. Total traffic is about 30Mb/s (up to 40) all day. I am in the process of migrating to a LinuxVirtualServer architecture for load balancing and failover. It works well. I have to say that tomcat is not so easy to share between nodes. I had to do at least one modification to catalina.sh (introducing a CATALINA_LOGS). The CATALINA_BASE is shared netween nodes (via NFS) and I need one catalina.out for each node. So... Oh, and last but not least, I didn't find a privilege separation method in tomcat (like in apache or ssh or postfix, or...). Perhaps am I wrong, but, if you want tomcat to run in unpriviledge environment, you have to make it bind to a public port (say 8080). I use iptables to redirect connections from 80 to 8080: If you have only one tomcat running on the server, you can use: /sbin/iptables -t nat -A PREROUTING -i lo -p tcp --dport 80 -j REDIRECT --to-ports 8080 For more than one (one IP for one tomcat is required), you have to deal with DNAT: /sbin/iptables -t nat -A PREROUTING -d 1.2.3.4 -p tcp -m tcp --dport 80 -j DNAT --to-destination 1.2.3.4:8080 This way, you don't have to put any port number in URLs.

RE: jk or jk2
Florian,
From my latest experience with my reconfiguration of Tomcat, Apache2 and mod_jk2 I
have somewhat figured things out. I think the bracketed items are a type:attribute
sort of like tags in XLM or HTML.
They are necessary to identify the individual pieces within the properties file. They
are neccesary for when you have mulitple Web applications running on either one
instance of tomcat or multiple instances of Tomcat.
I am including my newly revised workers2.properties file. As you can see I have
defined 3 ports that tomcat will listen on, i.e.
[channel.socket:localhost:8###] these need to be unique.
Then further down you can see where I have assigned the workers to the individual
listen ports, i.e
[uri:www.session1.com/*jsp]
worker=ajp13:localhost:8109
Now if you are only running one instance of Tomcat you only need one port and one
worker. But in my case I have each web application running on a seperate instance of
tomcat that I can turn on/off without affecting the other instances.
I hope that this helps clarify some thing for you.

Dean-
thanks for sharing your material on your tested setup here. I wonder if
you've got a distinct idea of how the syntax workers2.properties works.
This is actually my single most pressing problem.
There is this section like thing: [foo:bar] What does it mean? Is it a
[type:instance] - eg. [uri:/context/*]
scheme, perhaps? This might make sense. Then this
[type:] - eg. [config:]
could be a class or singleton-like thing. And then, the properties. Do
they always refer to the preceding square-bracketed item?
[type:obj]
property1=value1
property2=value2
What is the group syntax like? Is a group something I define with the
[lb:some_lb_name] statement? Do I need a shared memory file under all
circumstances, or is it neccessary only when I have several tomcats?

Re: Loading a class from a zip file , present outside Tomcat directories
Hi geeks,
Problem :-
I have a zip file which contains a .class file . I need to create an
instance of this class during runtime.
Below is the snippet from the actual code which does the same.
I was able to successfully load the classes when running test routine
using the same code through the command line.
But when i call the same API from the GUI [running in Tomcat 3.3.1] , I
am unable to load the class.It was giving me java.lang.ClassFormatError:
(Bad magic number)
NOTE : The zip file is not under the Tomcat directory.
I understand that the classloader mechanism for Tomcat is different.I
tried the following approach
- I tried loading it from the webapp classloader's parent, ie. right
upto the same system classloader as used by command line, by using
getParent() .(myPkg.tryMe.class.getClassLoader().getParent() ) ..
... but am still in same square, as am getting the same exception.
Any help on this is welcome.
===code snippet=
package myPkg;
public class tryMe{
public static void loadMyClass(){
URL[] urls = { new
File(C:\\tmp\\abcd.zip).toURL() };
String classFile=
com.xxx.yy.myClassToBeLoaded; // the class to be loaded from the
abcd.zip file
ClassLoader tempClassLoader
=myPkg.tryMe.class.getClassLoader();
ClassLoader cl = new
URLClassLoader(urls,tempClassLoader);
System.out.println(DEBUG: :Before calling
loadclass..:);
Object o = cl.loadClass(classFile).newInstance();
System.out.println( DEBUG:: successfully loaded
class ..);
}
} //EOC
===End of code snippet===
Thanks in advance,

I mean, the zip file can be anywhere in the hard disk, and not under the
installed Tomcat directory structure.
Please provide any pointers on how to go about it .
Thnkx in advance!

Tomcat won't start
One of our servers running Tomcat as started experiencing an odd problem. Tomcat will not start, it is complaining about not being able to find some classes. The problem started shortly after applying some updates using YAST. The exception it throws is shown below. We are running Tomcat 4.1.24 on JDK 1.4.1-b21 on SUSE 8. We have another server with a very similar config that works perfectly (only difference is the distribution it runs on, RH vs SUSE) I have checked CATALINA_HOME and JAVA_HOME and they both point to the correct locations. I modified catalina.sh to display the CLASSPATH it uses when starting catalina and included it as well. There are a couple references to this problem in the mailing list archives, but it was never answered. JAVA_HOME=/usr/lib/java CATALINA_HOME=/opt/jakarta CLASSPATH=/usr/lib/java/lib/tools.jar:/opt/jakarta/bin/bootstrap.jar Any ideas?

Re: generate images on the fly
Of course, there is always java.awt. In order to write the images out, you need to use javax.imageio, which is included in recent JDKs and can write to a variety of formats. I use this combination to accept image uploads, determine their size, store them in a database, and then serve them back at any resolution. I.E, the url for the image may specify the size the image should be scaled to. The system looks in a disk cache to find if the file has already been generated, and if not, generates it using the JDK. The JDK can read gifs but not write them, which is inconvenient but not the end of the world. In my case, I do use transparent images, but I work around this problem by accepting transparent gifs, and then (at request time) accepting a parameter for the background color onto which the gif will be drawn (in my case the bg is always solid). I then draw the gif onto a java.awt.Graphics that has been filled in with that color, and render the final scaled product as a JPG. I suspect I could make my life a lot easier by using PNGs but I haven't gotten around to it yet... -Erik Thorsten Möller wrote: Hi, slightly off topic but does anybody know an Java open source framework or class library which makes it possible to generate images (gif, jpg, png) on the fly on server side and send them to the client (or store them on the web app context)?

Pike, rumour is the GIF license is free again. Compuserve gave it up. Free software will (in time) be able to support it again ... if they wish... I didn't know that. That's great, if it's true. Another thing to consider: one of the important benefits of the GIF file format (transparency) is also part of the PNG format. PNG also supports 24-bit color, while GIF supports a measly 8-bit maximum (paletted) color depth.

Realms JSPs
Hi, I'm kind of new to JSP programming. I was wondering, is there a way to extract the username used to log in(I am using JNDIRealm for authentication), and use that data within the web application from the perspective of the JSP? Any help would be great! Thanks. Justin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
