using apache access control?
I'm using mod_jk w/ TC 4.1.18 Coyote connector. Is it possible to get apache to apply access control directives (e.g. basic auth, deny allow) to files mounted to tomcat? I'd like to be able to keep my access control in apache, so I don't have to set it up separately for my static and dynamic content.

Re[2]: apache2 + mod_jk(1) + tc 4.1.12 + load balancing
or maybe not. Apparently the load balancer doesn't use an exact round robin scheme. I'm seeing 6 requests to TC1, then 6 to TC2, and then back. Not that I mind... just it's been hard to tell if it's working! I recommend using lynx to hit a page that prints out something to stdout... then tail both logs and go nuts with lynx lynx www.myserver.com ctrl-c up arrow enter ctrl-c and watch the logs.

coyote exception
I'm trying to connect Apache2/mod_jk w/ Tomcat 4.1.12 Coyote via AJP13
over tcp socket. However, I get the following exception from my tomcat.
SEVERE: Caught exception executing

at java.lang.Thread.run(Thread.java:536)
Line 543 of ChannelSocket.java (rev 1.21 marked for Tomcat 4.1.12) is
the highlighted line of this method:
/** Process a single ajp connection.
*/
void processConnection(MsgContext ep) {
try {
MsgAjp recv=new MsgAjp();
while( running ) {
int status= this.receive( recv, ep );
if( status = 0 ) {
if( status==-3)
log.warn( server has closed the current
connection (-1) );
else
log.warn(Closing ajp connection + status );
break;
}
ep.setLong( MsgContext.TIMER_RECEIVED,
System.currentTimeMillis());
ep.setType( 0 );
status= this.invoke( recv, ep );
if( status!= JkHandler.OK ) {
log.warn(processCallbacks status + status );

this.close( ep );
} catch( Exception ex ) {
if( ex.getMessage().indexOf( Connection reset ) =0 ) {
log.warn( Server has closed connection);
} else {
log.error( Error, closing connection, ex);
}
}
}
So what is null on this line? I can only imagine it would be the
exception's message. So what exception is being thrown in this method
without a message, and how can I prevent it?
Config files follow.

Might there be multiple instances of a servlet (JSP-generated or otherwise) in my JVM? You might want to be cautious believing anything that book says about any topic, unless it correctly explains what is really going on. What book said this? For anything from Servlet 2.2 on (that's quite a long while back), it is not legal for the container to create more than one instance of a particular servlet definition *unless* that servlet implements the SingleThreadModel interface (or the JSP page has the isThreadSafe=false attribute on its %@ page % directive). The other thing to note is that doing this would not improve performance -- at best, it will have zero impact, but it's actually pretty likely to be negative (because the container is going to have to manage the multiple instances, because the maximum number of simultaneous requests to that servlet is now limited to the pool size you've configured, and because they take up more memory space). The only reason that SingleThreadModel exists is to allow you to create a servlet or JSP page that stores per-request state information in instance variables of the underlying class. This is not a good programming practice -- you should instead use local variables only, so that a single instance of your servlet or JSP page can handle any number of simultaneous requests.

Both systems are running Apache 1.3.23 and Tomcat 4.0.3. I have built mod_jk from the sources found in the jakarta-tomcat-connectors package and the build went smoothly on both systems. I have configured Tomcat to auto generat the mod_jk.conf file and that too appears fine. The problem I am having involves Apache. Each time I try to start Apache, with mod_jk enabled, the server will not start and I find this message in the error: [Wed Jun 12 14:27:40 2002] [emerg] (2)No such file or directory: Error while opening the workers I do have a workers.properties file in Tomcats conf directory. I have double check everything from permissions to making sure the file is named correctly and I still get the same error on both systems. Any ideas?

Re: mod_webapp and static content
mod_jk will allow you to do this. though it's a bit more complex to set up.

Perhaps using another connector besides mod_webapp? Alex From the tomcat 4.0.2 release notes: Currently, mod_webapp forwards *all* requests under the specified context path to Tomcat for processing. In a futher release, it will automatically configure itself to serve static resources from Apache *unless* the resource is subject to filtering, or subject to a security constraint, as defined in web.xml. No extra configuration in httpd.conf will be required. So the goal is to have Tomcat serve only JSP and servlet requests, and have Apache handle all the rest. Tomcat stand-alone is not built to be a very efficient static content server...for smaller sites and sites with low bandwidth needs Tomcat stand-alone would probably be suitable for serving all content. Anything bigger, with lots of images or other static content, etc. would be much better off using a Tomcat/Apache combo, as Apache is very good at serving static content, much better than Tomcat. -- To unsubscribe, e-mail: mailto:tomcat-user- [EMAIL PROTECTED] For additional commands, e-mail: mailto:tomcat-user- [EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

This won't work to the general world, but you can set up a hosts file entry for the ServerName and use that in your URL when you make a request to the server. Not sure if you need to set up host file entries for the vhosts on the web server itself. I'm pretty sure you do.

Re: jsp servlet error in NetBeans
btw, We suspect this may be related to our shared SMB filesystem and bad SMB file locking in OS X. Make sense at all?

Re: triggering JSP page recompilation
As I mentioned before, GNUJSP keeps a record of what files include what, and if told to, recompiles all including files when an included file changes. I don't recall gnujsp doing this--I've always had to touch files when I change an included file with gnujsp as well.

4.0.1 in production?
How many people are using Tomcat 4.0.1 in production currently--and how well is it working? If used with Apache, which connector are you using? If you're not using Apache, how well is Tomcat holding up serving static content? Thanks for any responses!!
