Some advice regarding mod_jk
Hi, I am developing an using mod_jk, apache 1.3.26 and Tomcat 4.1.7, Redhat 7.2 and have come across an issue with regards to mod_jk. Now I assumed that the Ajp13Processors under mod_jk acted as pool to process incoming requests. But I hadn't realised that a processor is created per socket and then it processes requests on that socket until it is shut down. This means that even on a lightly loaded machine I can quite easily have 7-8 processors (hence threads, hence processes) depending on which apache child processes my request. I would like to modify the code for the Ajp13Connector as follows, and I wonder what the developers think the consequence would be for reasonble sized sight (say ~10,000 hits a day). 1. Add a maxIdleProcessors, so that short periods of peak activity don't leave loads of processors hanging around. I would probably set this value quite low (probably 2-3). 2. I would modify Ajp13Processor so that it processes a single request and then recycles itself, rather than waiting for more requests on the same socket. I have made these changes and tested them and the behaviour doesn't appear to be too bad. Peak activity does slow a little bit, but overall usage of resources (i.e. threads) is much lower.

Re: webapp- who handles static content: Tomcat or Apache (* OFF TOPIC *)
Interesting idea to split the static content onto a different server. Does anyone know how a browser like IE handles this kind of situation, I know that with HTTP 1.1 the server will leave the connection open for further requests so that images/styles, etc should be able to go through the same connection as the original call. Will IE open a single connection to images.foo.com to retrieve all the images on a page, or will it open a new connection per image. What happens with an SSL based page, will I get annoying messages because I am getting insecure content. I assume I will have to put an SSL certificate on the image server as well.

Re: JNDI with a custom factory not working
Remy, I will send you the config files shortly (they're on a laptop I don't have access to at the moment). My situation does have one unique feature. The servlet which is causing these issues is in a jar which I have installed under common/lib. The reason I have done this is because the servlet acts in a similar manner to the struts controller servlet, in that it catches all urls and then dispatches to appropriate action classes. All action classes are also in this jar so I shouldn't have any classloader related problems, the web applications have some config files (accessed via getResourceAsStream) and JSP files. That is the only difference I can think of, everything else is normal usage. As I say I will forward you the files later today or early tomorrow.

This is an initial investigation so my analysis may be FLAWED. Remy, does this explanation of how the naming contexts are defined/used make sense ? I'm not sure I understand very well, so I'll assume it's a problem with the links. The global resources defined in server.xml are not accessible by default in the web applications (because you may want to restrict some to specific webapps, etc). So you have to link them using a ResourceLink element. You can also define the resource links in the default context so that all your contexts in your host or engine will have the link, instead of having to define it in each one. The admin webapp will have full support for this shortly (I reckon that configuring this is *hard* at the moment). Remy Remy, Thanks for you response. I didn't make myself very clear, I'll try again. The Problem = In the server.xml have defined a global resourcce under the name rohas/filecache. The resource params defines a factory along with other attributes. In my context I have defined a ResourceLink that maps to the global name (I have given them both the same name, I assume that doesn't make a difference). In the web.xml for my application I have defined a resource-ref that points to this resource. When I try and access the resource via an InitialContext in the init function of my servlet, I get a NamingException from org.apache.naming.factory.ResourceFactory.getObjectInstance. To look into the problem I put some debug into the org.apache.naming.NamingContext class in the lookup method. I noticed that when this class was called a few times, the name member varied between //Standalone/myapp amd //Standalone/localhost/myapp, etc. I was a bit surprised because I thought when I asked java:comp/env I would always get the same NamingContext and not different ones. I then traced the code through org.apache.naming.java.javaURLContextFactory, which in turn uses org.apache.naming.SelectorContext. The SelectorConext class uses getBoundContext to retrieve the appropriate NamingContext to which it delegated the lookup/bind/unbind, etc. The getBoundContext then uses ContextBindings.getContext to get the context (if doesn't exist then it creates a new one). *** IMPORTANT *** The member variable initialContext is overriden inside the if of this function (is this intentional). ContextBindings appears to return a NamingContext based on the class loader currenty in used. Hence the multiple contexts and why the name I am

Problem with url session encoding - Tomcat 4.0.4 b2
Hi, I am writing an e-commerce application using tomcat and have come across a minor issue with url session encoding. The problem is that if a valid session id is available on the url then tomcat does not use cookies. Here is my scenario :- 1. I have tomcat configured to use cookies for session id's if possible. 2. An access to the index.html of my site redirects via url encoding to home/index.html. This causes the session to be sent both via the url and a cookie, from here on tomcat knows it can use cookies and doesn't bother adding the session id to the url when I use encodeURL. 3. If I close the browser and open a new browser and use the url history box then the url that appears is home/index.html with the added url encoding (because I redirected from the original index.html). 4. Because this url has a valid session id, tomcat now defaults to using the url endoing method and doesn't even try to use a cookie for this browser session. My problem is that I want tomcat to always try and use a cookie even when using url encoding (unless it is already using a cookie). I realise it is a pain for those users that have setup prompts before accepting cookies, but in my case I would prefer an inconvenience to a small number of users and not the vast variety of users seeing the session id on all their url's. My own prefernce would be to overload the cookies parameter so that a value of force would cause this behaviour and leave the existing semantics for the already defined values.

At the least, compatible option is needed. I don't think that my intent was to be compatible with Apache. My first goal was to be compatible with Java localization. The context in which I am using Jakarta is as an 'embedded' servlet container inside of a Java application. This is something which I am currently in need of for a project. The only reason I can see support for the Apache model is that the new mod_webapp connector I believe is structured so that static html is served by Apache and the dynamic side by tomcat, under these circumstances it would be better if they were both the same.

catalina classpath question
Hi, I am trying to setup an application under Catalina and can't seem to find a way to add another directory to the CLASSPATH for a web application. Is there a way to add a directory like "WEB-INF/resources" to the CLASSPATH. I can solve my problem by adding my files below "WEB-INF/classes", but I would prefer not to do that. Regards, Arshad

So, even if we modified it to be non-spec-compliant, your app would still not run in any other container. Craig
Re: Catalina + Apache
Can you recommend any documents for trying to understand the architecture of mod_webapp and catalina connectors, or is the source the best place. I am fairly keen in getting involved in this area, so any indication of where to get started would be gratefully received. I am a fairly good 'C' and Java programmer.

It makes much more sense to do this way. However, I _did_ do this as you mentioned: I have *.jsp and *.j mapped to specific servlets in my ROOT/WEB-INF/web.xml and all I got was the output of index.jsp as something Netscape had to download. telnetting to the webserver port revealed that the index.jsp was being served by Apache, not Catalina. I'll mess around with it this weekend and see if I can get it to work "as advertised" and report back my results, but I have a couple of guys waiting on a servlet container that works with our *.j framework to test today, so I'm temporarily falling back to 3.2. I'm really happy that this approach is being followed as it's much more (ultimately) intuitive than the way it's done in 3.2 because it's simpler. I'm glad you like it, although you should really thank Pier Fumagalli -- it's his vision (which I agree with) and effort that has really been working towards this. As I mentioned several times, what I was describing is the *theory* of what mod_webapp is supposed to accomplish. To ensure that it becomes *reality*, please feel free to volunteer your time (as you did above) in testing the current connector, identifying places where there are bugs, posting patches, etc. I know Pier has a bunch of bugfixes currently in his local CVS tree, so hopefully we will be much closer to the "reality" end of the scale soon.

I see nothing like this for TC4. Can someone enlighten me? The design goals for mod_webapp say that it should respect web.xml mappings -- in other words, if you added a servlet-mapping entry for "*.foo" to a particular servlet, then that is what would happen at runtime. I totally do not understand this! I'm dense or something: How does Apache / DSO* know about something in the web.xml? This is the key architectural difference between mod_webapp and the current generation of connectors. When mod_webapp establishes its initial connection from Apache to Tomcat, the configuration information (extracted from the property getters of the internal Context object) is sent back to the connector in order to configure everything about this particular webapp. From the sysadmin perspective, this means we can forget all about having to configure things twice (once in httpd.conf and once in web.xml). It's also a requirement of the 2.3 spec -- if we create a "servlet container" using Apache+Tomcat together, it (the combination) must still obey all the servlet spec requirements, including respecting things in web.xml. If I grok you, this still relies on having /foo mapped to the servlet container in Apache. I'm in a situation where Apache's DocumentRoot _is the same as_ the top level of the WAR, but I want Apache to serve the *.html and *.gif and *.jpg and *.png and I want Tomcat to only do the *jsp and a special mapping (in this case *.j). Then what you'd want is to configure the ROOT webapp to have a context base equal to your Apache document root. If you want things mapped to servlets, just do them with servlet-mapping entries *exactly* like you would for Tomcat stand-alone. As I mentioned earlier, the connector takes over the "default servlet" mapping, so it will handle everything that is *not* explicitly mapped to a servlet (i.e. all the static files). Again, this is all the design goals -- I have not tested the current implementation to see if it achieves these goals yet. In particular, I recall seeing bug reports about mapping the ROOT context. The primary difference between Tomcat 4.0 stand alone and Tomcat 4.0 behind Apache is the mapping for the "default" servlet. In the stand-alone case, this is mapped to the Tomcat servlet that serves static resources. In the connected case, they would be served by Apache. I don't see how this works in my case. I'm being dense, I think. If you were running Tomcat stand-alone, you would
Query regrading mod_webapp
I have been trying to configure mod_webapp (without much luck) and I notice that wa_host will not allow applications to be mounted which have common heads (i.e. '/' and '/examples/'). Tomcat itself doesn't seem to have any problem with such a setup. Is this a genuine design decision?

Re: Any solution for bug#696?
Hi, I have downloaded the latest tomcat-4.0-b1 binaries and have been trying to get it working on with Apache 1.3.12. 1. Apache 1.3.12 complains that the mod_webapp.so in the linux directory was not compiled with -DEAPI and may crash. I rebuilt it from the source and this error went away. 2. When I try and use catalina via apache I get a error (-2) cannot connect to localhost (127.0.0.1). The ServerName in my httpd.conf is 'localhost' and as far as I can tell no changes need to be made to the server.xml. 3. Does anybody know how the ROOT context can be served via apache. Apache keeps complaining that another web application has already been registered for '/'.
