Does Jasper use the Context Classpath
Greetings! I know there are two (or three) different classpaths within Tomcat 3.2. The question is, does Jasper, when compiling JSP files, use the Context Classpath, which referrs to the WEB-INF/classes directory for that specific JSP? If not, how could I add the Context Classpath to the Jasper code? Can someone point me to a breakdown of the classloading within Jasper specifically? I've seen the classloading for Servlets, and that is all kosher. Thank you in advance for any tips, pointers, or direction.

But I need individual contexts for each virtual host. For virtual hosts, you are either running Tomcat 3.2 and using the Host parameter in the server.xml file, or running multiple copies of Tomcat 3.1. If you are using the Host paramter, you'll have to add the contexts manually, or you can look at the admin servlets distributed with Tomcat. While I couldn't get them to work, apparantly there is a context manager that allows you to view, add and delete contexts from within a host section of the server.sml file. Good luck! Will

JSP's not finding classes in WEB-INF

Those classes are located in the WEB-INF directory, under the /classes folder. I assume these are your bean classes. These should be put under the WEB-INF/lib directory rather than the classes directory. The classes directory is ment only for un-jarred servlet classes that have been declared in the web.xml file. Actually, just to make things interesting, those *are* servlet classes. We have both servlets and JSP's that use library classes for various things. Currently, they live in WEB-INF/classes. One of these years we'll get things sorted out a bit better. Put any servlet jars, beans, and required non-statndard libraries under the lib folder (like log4J, or xalan) Ok, so I created a jar file with the servlet classes and library classes in it and moved it to WEB-INF/lib. Didn't work. I cannot put this .jar file in TOMCAT_HOME/lib -- each context / virtual host will have slightly different bits in the servlets. Will

Hmmm. According to Dr. Mel Martinez on the tomcat-dev list, Jasper *cannot* see the web-inf/classes part of your web app for compliation.

Running multiple virtual hosts with one JVM
Hello! The idea I've got is to run 2 or 4 or 8 virtual hosts, all doing the same thing, under one JVM. I got this working several months ago, but it has slipped my mind as to how to do this. I recall having each virtual host having its own unique web.xml file, it's own unique WEB-INF directory, and the WEB-INF containing a complete set of the classes for the application. Each virtual host was configured in the apache conf file, pointing to different ports. Each port was listend to in one server.xml file. Each different port pointed to a unique WEB-INF directory, as mentioned above. Does this sound correct? Are there better ways to have multiple virtual hosts running under one JVM?

Regarding moderating the mailing list, I don't think that is feasible. For one thing, as some have suggested, it would take a lot of work, so it would be hard to find people to do it. Plus philosophically, I'm not sure we really want to go that route. And of course, there is a list owner (that exists as an entity, if not a person or persons, even if they don't show themselves around here much :-), and they'd get final say it what happens with this list. That may be the biggest point, because there has been no input from any owner on this list for a while on any of these issues (although they are on record as saying a newsgroup is a bad idea, mostly because many people don't have access to newsgroups because of firewalls, proxies, and such). Also, no disrespect intended, but I'm not sure it's such a good idea to try to come up with sweeping ideas to improve a mailing list after having only been subscribed a few weeks. That's not very long to get to know the ins and outs of a mailing list, how things ebb and flow, what's been suggested/tried or not, etc. Anyway, of the recent ideas suggested, I think the one that has the best combination of merit/feasibility is dividing up the list into sub-lists. This would have to be done carefully, of course, to actually improve the situation. I'd be willing to give this a go (although it might be the kind of thing where it would be good to have more than one person involved). The first step though, would be to try to get in contact with the list owner and see if they would go for it. I'll try doing that.

Multiple Unique Instances WITHOUT multiple JVM?
Greetings! Here's what we want to do: We want to host our new servlet product as an ASP. Each customer of ours would get a unique configuration for the product. However, all of the servlets would run from one code base.

Re: Multiple Unique Instances WITHOUT multiple JVM?
On Tue, 24 Apr 2001, Sam Newman wrote: I think there is a simpler solution. Firstly, have one web app. Secondly, have a database (could even be an encyrpted text file) containing user information. That, unfortunately, wont work. Each customer has many users. Each customer also has many proprietary data files that only the users of that customer can see. Each customer requires a virtual host (customer1.ourhost.com). The codebase is already written based on having only one customer per machine. Now the spec has changed, and they want multple customers per machine. Each customer needs custom configuration data read into a class, and the class may or may not be running under a servlet. The idea is to put out multiple WEB-INF directories with customer-specific config data, images, binary files, etc. Then, have the config set up like such: apache config: VirtualHost ApJServMount /servlet ajpv12://host.server.com:8007/servlet/customer1 /VirtualHost VirtualHost ApJServMount /servlet ajpv12://host.server.com:8007/servlet/customer2 /VirtualHost and so on, mounting each virtual host to a different entry in the server.xml on one JVM. server.xml Context path=/servlet/customer1 docBase=/webhome/customer1 debug=0 reloadable=true /Context Context path=/servlet/customer2 docBase=/webhome/customer2 debug=0 reloadable=true /Context Each Context would have its own unique WEB-INF directory that could contain the web.xml file and other text files with configuration data. Is this going to work at all? Can one JVM manage multiple WEB-INF directories? All library classes will be in the main class repository; only config and binary data will be stored in the WEB-INF directory for each customer. Thanks again for pointers, tips, etc...

Does mod_jk require 3.2? (was :Re: Multiple Unique Instances WITHOUTmultiple JVM?)
On Tue, 24 Apr 2001, Jeff Kilbride wrote: Hi Will, Take a look at the mod_jk HowTo at: http://jakarta.apache.org/tomcat/jakarta-tomcat/src/doc/index.html There's an example virtual host configuration using a single JVM at the end of the file. No way - I can just mount /webhome/customer1/servlet like that? No aliasing from /servlet/ to http://server:port/servlet? Whoah. So, does mod_jk require using tomcat 3.2? Will
Books on Tomcat
Hi! Does anyone know of any dead-tree books that document the Tomcat platform I've checked O'Reilly and Amazon, with no luck. I've found a few simple basic articles, but that is it. Thanks in advance! Will -- If Al Gore invented the Internet, then I invented spellcheck!

Logging, server.xml and so on
Greetings!
After many days of searching and so on, I am still looking for information
on using the default logging built into Tomcat.
I am running Tomcat 3.2.1 under apache 1.3.12 on Solaris 2.7, with Java
1.3.
I have a servlet application set up that catches all the 'expected' errors
and logs them to text files, databases, etc. This includes bad input,
missing or wrong parameters, and so on.
However, I still need to catch 'unexpected' errors at the top level and
log them to a standard log file. Currently, I just am doing this:
} catch (Exception e) {
e.printStacktrace();
}
This is fine for development; at least I can see on the console what
happened. However, for production rollout, I'd sure like to be able to
have some real logs.
I have checked google, groups.google and the mailing list. I do not want
to simply do a `tomcat start 21` log, I want actual java interfaces to
a logger object that can write to the log listed in server.xml.
My server.xml file currently has a log listed:
--- server.xml excerpt ---
Logger name="tc_log"
path="logs/tomcat.log"
customOutput="yes"
verbosityLevel="ERROR"/
--- server.xml excerpt ---
However, this isn't working yet.
Also, in the ContextManager section of server.xml for my servlet, I see
this line:
!-- ContextInterceptor className="org.apache.tomcat.context.LogEvents" /

As you can see, it is commented out. I have not found any references to
this in the FAQ or docs; of course it is entirely possible I have
overlooked this. Uncommenting this did not change anything.
I have also tried to import org.apache.tomcat.logging.* into my servlet to
create a logger or TomcatLogger class, but the "package
org.apache.tomcat.logging does not exist".
SO, in a nutshell, how do I get access to a logger object to log errors
and exceptions to the log referenced in the server.xml file?
Thanks in advance for any tips, pointers etc.
Will

To get stuff into the log, you have to do the following (I'm assuming your
in a servlet at the time!)
this.getServletContext().log("msg");
or
this.getServletContext().log("msg", exception);
Check the API docs for HttpServletContext for more details. As to how you
can tailor this logging to reflect the debug level set for your context (ala
log4j), I don't know. This works a treat in all my stuff anyway.
Damn. Missed it by *that* much. That's too simple. Thank you.
