Various bugs with mod_jk and mod_jk2? And does Apache2.0.43+mod_jk2=inevitablehanging?
Hello, I wanted to get Apache 2.0.43 and mod_jk2 working. They seemed to setup fine, and handle requests just great. But after a while, Apache starts hanging on every other request. I tried mod_jk, and it still does this. I removed all traces of both mod_jks, and it still does eventually starts hanging, even on static image requests that are not run through Tomcat. I'm assuming it's a problem with Apacheand my setup (Redhat 8.0). Anyone else have similar issues? Anyhow, so I went back to Apache 1.3.27, which does not hang at all. Now, here's where I noticed two weird things: #1) Apache 1.3.27 with mod_jk2 - mod_rewrites that have the [P] flag to proxy don't seem to actually get interpreted and sent over to Tomcat. #2) Apache 1.3.27 with mod_jk - mod_rewrites DO get interpreted. But, with Apache and Tomcat residing on two physical servers, Apache does not send over a request for index.jsp if the URL does not exactly specify it, even if the DirectoryIndex is set. (So, /index.jsp WILL go to Tomcat, but / will not, and is just processed as an Apache level index view.) I've had to actually create fake index.jsp files in a mock directory structure on the Apache side to trick it into sending index.jsp as default to Tomcat. Does anyone know how to fix either of those strange behaviors? Or BETTER yet, has anyone had the hanging problem with Apache 2.0.43 and mod_jk2, and found a way to fix it?

WebDav Problems
Hi, I use tomcat-4.1.18 and have the following problems with webdav. The Windows Client (webdav folder) does not show the modification dates of the files neither over the list nor for properties (I'm not sure whether thats called properties because I use German Windows, but I mean selecting a file and right mouse and the last menu entry to get info about file such last modified size etc.). This happens with tomcat after downloading and installation, thus we have done NO modification on tomcat. How can I get the date listed? The second problem is that webdav does not work correctly (it gets problems with directory names) when I change its url mapping. We have to do that because we want to integrate webdav into our application. The problems occur with the original tomcat-4.1.18 after modifying the url mapping. Any ideas how to solve this problem?

Brandon, the scriptlet in your jsp gets your server's cookies from the client:
Cookie[] cookies = request.getCookies();
but on the initial request, there are no cookies set by your server on any
given client, so getCookies() returns null in accordance with the servlet
spec. That triggers a NPE when you try to process the cookies later:
for (int i=0; icookies.length; i++) {
...
}
Put an if statement around your for loop to check if cookies is null or
not and that should fix your problem.

Document Root
I just started messing around with Tomcat and would like to know if I can change the Document Root to a location which I prefer. For example, my machine (windows) has 2 partitions, c: and d:. C is where I store my program files, including Apache, Netbeans, Tomcat, etc. And D is where I have source code files which run under Apache. In my httpd.conf file I have DocumentRoot d:/is/clients/. Now what makes this a Tomcat question is that I would like to have d:/is/java (notice that it's not under my apache docroot) as my directory for my java source code, so how can I do it. Foolish question but need clarification. What are the differences between c:/tomcat/work/standalone/localhost and c:/tomcat/webapps. For example where do I put my code?!? I am wondering because the docs say c:/tomcat/webapps, but yet when I hit localhost/examples/... it goes to c:/tomcat/work/standalone/localhost. Hope I make sense.

Basic questions
Hey all :) Throughout my learning experience with Tomcat, I have gotten curious about the following things. This is mostly just for informational purposes. Inquiring minds want to know ; ) #1: Is it possible to set Tomcat to restart (as user tomcat) on a schedule? #2: Is there anyway to set something up that if a user attempts to access my app within a specific time frame they are redirected to a different page. For example, when my user accesses my webapp they go to www.myhost.com/mywebapp and they are brought to index.jsp page. However, if the same exact URL is accessed within a specific time frame, they would be brought to index2.jsp. Thanks!

Re: WebDav Problems (same problem + hint)
The second problem is that webdav does not work correctly (it gets
problems with directory names) when I change its url mapping.
Yes, I have the same problem and I really think it's a bug in the servlet.
It doesn't seem to consider its url mapping internally (not at all or not
correctly).
I tried the following:
MyDavServlet extends WebdavServlet {
protected String getRelativePath(HttpServletRequest request) {
String res = super.getRelativePath(request);
System.err.println(translating path + res);
if (res.startsWith(/XDAV)) res = res.substring(5);
if (res.length() 1) return /;
return res;
}
}
Without this modification, Windows webfolders do not work at all.
With this modification, they work, but not 100% correctly.
Every folder (collection) also seems to contain itself. Funny effect.
== My patch is not the solution, but probably a pointer to the problem...
I haven't spent more time with it (yet) because I don't use it yet. I just
stumbled across this problem after just 10 minutes of experimenting :-(((
Holger
We have to
do that because we want to integrate webdav into our application. The
problems occur with the original tomcat-4.1.18 after modifying the url
mapping.
Any ideas how to solve this problem?

Re: session across different domains ?
I think you will have to code specifically for Tomcat. The only way to get
jsession encoded into your string is with Request.encodeURL or
Request.encodeRedirectURL, but they won't do it because Tomcat will
determine that encoding wasn't necessary, and will return your string as-is.
isEncodeable() is quite strict in Tomcat.
Here is from org.apache.catalina.connector.HttpResponseBase:
/**
* Encode the session identifier associated with this response
* into the specified redirect URL, if necessary.
*
* @param url URL to be encoded
*/
public String encodeRedirectURL(String url) {
if (isEncodeable(toAbsolute(url))) {
HttpServletRequest hreq =
(HttpServletRequest) request.getRequest();
return (toEncoded(url, hreq.getSession().getId()));
} else
return (url);
}
See this which does the Tomcat servlet container's encoding:
org.apache.catalina.connector.HttpResponseBase.toEncoded()

When you link to the new domain, URL encode the session id into the link. I
think either the servlet spec or tomcat docs should tell you you can do
this.

Re: Urgent problem with Singleton
Craig,
As well as synchronizing that block and setting reloadable=false in the
server.xml I paid close attention to when these extra instances are being
created. When the server start and no requests have been received there is
only the 1 instance. However as soon as a single request is made another 2
instances appear. From then on no more get created. I am not modifying code
on the fly either. Any other ideas?

Subject: Urgent problem with Singleton
Hi,
I have a task scheduler thread that implements ServletContextListener
and starts up as a listener with the following code from my web.xml:
listener
listener-class
mypackage.MyServlet
/listener-class
/listener
My problem is however I need this to be a singleton, its imperative.
There always seems to be about 3 threads created though.
The number of threads that Tomcat creates is *totally* independent of the
number of listener instances that are created.
I have tried
numerous things including making this servlet call a singleton class to
do the task scheduling but it still ends up with 3 threads. This is
causing terrible concurrency problems that wouldn't exist if this was
working properly. My serlvet code currently resembles the following:
boolean hasBeenInitialized = false;
public void contextInitialized(ServletContextEvent sce)
{
if(!hasBeenInitialized)
{
//Start up the task scheduler thread
hasBeenInitialized = true;
}
}
I am using Tomcat 4.1.18, Apache 1.3.27 under RedHat 7.3. I didn't have
this problem under wn32 only Linux. Any help, or ideas on how I can get
this to be a single instance would be greatly appreciated. Thank you
At webapp startup time, Tomcat is supposed to create one and only one
instance of each declared listener, and call its appropriate init method
(contextInitialized() in your case). However, there's a bug in 4.1.18
(and earlier 4.1.x releases) where, if you are using Tomcat's auto-reload
facility, the list of listeners doesn't get cleared so a new instance of
the listener gets added each time you reload the app.
This will be fixed in 4.1.19 -- in the mean time, be sure that you avoid
Tomcat's auto-reload facilities if you depend on the listeners being
singletons.
A class that implements ServletContextListener should *not* itself be a
Servlet, by the way. The only purpose for such a class should be to
initialize resources that your webapp needs, not to also respond to
requests.
regards,
Dave

RE: [ OT ] what source code control system?
Renaming the file in the CVS repository makes it impossible to build old versions of your code. If you rename the file within CVS, then CVS thinks that file has always been called the new name. Checking out old tags will give you the file with the new name, not the old name. Most likely this will break your build. In general, renaming the file in the repository is a really bad idea and should be done only in very carefully considered circumstances. The only safe way to rename a file in CVS is to remove it and re-add it with the new name. Kinda lame.

Raiden [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED]... Just as a followup, even though all of the below still holds true, I did find out my problem with Apache 2.0.43 (it was a DNS misconfiguration that eventually held Apache up, even though I don't have it resolving host names). So, Apache 2.0.43 is now running fine with mod_jk2. However, it still has the problem where DirectoryIndex won't check for an index.jsp through tomcat by default, which creates a problem for those of us that have Apache on Tomcat running on separate machines. And how, exactly is Apache supposed to figure this out? ;-) The simplest way to work around this is to create a minimalist directory structure on the Apache box with dummy (e.g. zero length) index.jsp files. Apache can then figure out that it needs to serve 'index.jsp', and send the request to the Tomcat box to serve the actual page. Anyone have a workaround for this? (Besides creating empty index.jsp files to trick Apache). Thanks, -Raiden On Sat, 11 Jan 2003, Raiden wrote: Hello, I wanted to get Apache 2.0.43 and mod_jk2 working.

I'm assuming it's a problem with Apacheand my setup (Redhat 8.0). Anyone else have similar issues? Anyhow, so I went back to Apache 1.3.27, which does not hang at all. Now, here's where I noticed two weird things: #1) Apache 1.3.27 with mod_jk2 - mod_rewrites that have the [P] flag to proxy don't seem to actually get interpreted and sent over to Tomcat. #2) Apache 1.3.27 with mod_jk - mod_rewrites DO get interpreted. But, with Apache and Tomcat residing on two physical servers, Apache does not send over a request for index.jsp if the URL does not exactly specify it, even if the DirectoryIndex is set. (So, /index.jsp WILL go to Tomcat, but / will not, and is just processed as an Apache level index view.) I've had to actually create fake index.jsp files in a mock directory structure on the Apache side to trick it into sending index.jsp as default to Tomcat. Does anyone know how to fix either of those strange behaviors? Or BETTER yet, has anyone had the hanging problem with Apache 2.0.43 and mod_jk2, and found a way to fix it?
