Re: adding servlet definition to context on the fly :Tomcat 5.5
[EMAIL PROTECTED] wrote: Hi, I had written some code to dynamically add a servlet to a context in a deployed applicaiton in Tomcat 4.1. This code basically uses the catalina loader to obtain the server-engine-host-and context, and invokes the addChild method after configuring a StandardWwrapper to represent the servlet I am adding. This all works fine in Tomcat4.1 and I am able to access the servlet through the right url immediately, without having to restart Tomcat. However, I tried the same code in Tomcat 5.5 and it does not work. It does not throw any errors, but simply does not recognize the url pattern once i actually try to invoke the new servlet. I was wondering if anyone had tried this before, and if so if they have any suggestions as to why this does not work in Tomcat 5.5? Are you calling addServletMapping() on the context after you have added the wrapper? It looks like this was unnecessary in 4.1.x but is required in 5.5.x. If that isn't it, I would suggest attaching you favourite IDE and debugging your way through the request mapping process to see where it is going wrong. This certainly should be possible. As an aside, version 3 of the servlet spec is expected to include this sort of functionality in the Servlet API.

I'd luv to see that code... the stuff you playing with is in Tomcat

But I think this answers your question...
public void addChild(Container child) {
throw new IllegalStateException
(sm.getString(standardWrapper.notChild));
}
is what addChild now looks like in 6... if they did allow it, now
they dont (;
I don't know where you found that code but that isn't the
StandardContext.addChild() code for 6.0.x. Even if it was, the OP was
asking about 5.5.x, not 6.0.x

Tomcat with support for asyn servlets (3.0)?

A plugin worker in the sense of a worker configuration item in workers.properties is 1:1 with a connection pool, and a connection pool doesn't create threads. It will grow at most as the lower of thread number and configured pool size. Well, no, maybe we need to go some steps back. I am talking about JK workers (isapi plugin workers), and I have no IIS workers: the problem is on IIS 5. As I said I have a connection_pool_size currently set to 300 on the JK worker (IIS side) and a matching maxThreads set to 300 on the Tomcat side. What you are telling me is that I don't have 300 threads on this IIS/JK worker side, but simply (a maximum of) 300 tcp connections to the Tomcat instance, is this right? So maybe I am just out of connections.. But if you are really actively using 300 connections, it means there are 300 requests processed in parallel inside Tomcat. So you should first check with the thread dump, what those are actually doing, and whether it's a good idea to send even more requests there. If the web server can't acquire another connection from the pool, further requests should fail, not block.

Ram... listen I got it going, but not on TC 5... it works on TC 6.
Got to tell you I cant see how this ever worked on TC 4 or 5... the reason
is the class loader structure doesnt lend itself to it.
Webapps cant see the Container... so I'm wondering how you structured it
without changing TC completely?
Possibly this code came out of an embedded app
Anyway... the tip is, if you want to make your life relatively easy... move
to TC 6 its has a flat classloader structure, so you only got to jump thru a
few hoops...
The code looks OK... but I'd suggest you add much more debugging points...
so you can watch what its doing...
And then my first gut feel stands... I would much rather go for a
specialized invoker type servlet with my own custom classloader...
possibly too much work but a much better solution...
... if anyone knows how one can structure this sort of code in TC 4 or 5
I'd luv to hear it.
But its an excellent idea... this idea of Servlet Injection or Servlet
Late Binding... if there is anything out there that does this, I'd be keen

Otherwise its something we going to add to the our PAS drop a servlet in

Re: useSendFile=true skips compression
Thanks for the explaination. So either I take the performance hit if I have high volumes, or the clients take a performance hit if I dont use compression. Is there some way I could get the best of both worlds? Maybe compress the files on the filesystem, then use a filter to programatically change the content type of those specific files to gzip? I suppose that would save some CPU as well, since the files wouldnt need to be recompressed with every request. Of course that also means that browsers without gzip abilities are SOL, but then again, this is a GWT app, so I am assuming a new browser (sorry lynx, no support).

RE: Regd....ASF Bugzilla - Bug 45015 (Quoting in attributes)
Hi, Actually our code base too huge to modify this quotes thing! So we want to disable this validation? But I do not understand how I can make the compiler ignore this validation. We use precompiled JSPs.

This is my first post. Please help!! I happened to see this page https://issues.apache.org/bugzilla/show_bug.cgi?id=45015 where in the comment 7 have provided references to the system property which could relax this check in JSPs. We use precompiled JSPs and at compile time I get this error with apache-tomcat-6.0.18 and java 1.5 in windows xp (Our deployment target is RHEL 5 ). Can you help me out in how I can set this system property in the tomcat 6.0.18 or build.xml jspc ant task? Thanks Subir Please do not print this email unless it is absolutely necessary.

RE: Problem with jasper-compiler when ported web application from tomcat 5.5.9 to 5.5.26
Even after clearing work directory on 5.5.9 this code works. I have 2 workarounds for this problem 1) Use following jars from tomcat 5.5.9 in tomcat 5.5.26 jasper-compiler.jar, jasper-compiler-jdt.jar, jasper-runtime.jar. 2) Keep def.jsp at same location as test1.jsp and abc.jsp. With both these workarounds my application works fine. I wanted to know what change has happened in above mentioned jars from tomcat 5.5.9 to 5.5.26 which is breaking my code?

If abc.jsp and def.jsp are in different directories, then it should be jsp:include page=../dir2/def.jsp It might be that on your 5.5.9 there is some old compiled copy of def.jsp in the wrong place. I.e. it might be if you clear your work directory on your 5.5.9 host the problem will reappear there. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
