On a side note: It is annoying that JProfiler assumes that a static field is a GC Root. YourKit is way better on this particular aspect, but I like the rest of JProfiler better! But it is even more annoying that the bleedin' SUN JVM and the JVMTI API even has a concept of Other GC Root - the guy that invented that JVMTI fieldname should have stopped for a moment and thought about What can _possibly_ constitute other GC roots? I must be a sloppy coder, I should quit this job: Inventing a special type for my non-understanding of garbage collection is a clear sign of incompetence. And what about the guy that implemented the JVMTI interface in SUN's JVM: ah lookey here, an I can't bother to find the source of this root-type root! I'll use that for pretty much anything that's in here, coz' I'm so fantastically lazy!. The problem is that most of the time, the WebappClassLoader that apparently is holding my entire universe and just won't let go, has Other GC Root as its GC Root.

help to solve 'OutOfMemoryError'
hello I am running a java program which makes a HttpURLConnection randomly, using Tomcat 5. I use Asterisk-JAVA API. After the program runs for an hour, it returns a java.lang.OutOfMemoryError and the HttpURLConnection is not established, but again it returns to normal and the UrlConnection works. This occurs on a random basis. I use Netbeans IDE in Debian Linux. The netbeans.conf contains: -J -Xms32m -J -Xmx256m -J-XX:PermSize=32m -J-XX:MaxPermSize=96m -J-Xverify:none What changes do I need to make to avoid this OutOfMemoryError? How can i try to change the configuration of the servlet container's JVM? I am completely new to both tomcat and java.. and would be very grateful to get some ideas.

This _really_ bugs me! | | Surely it's not a Tomcat problem anyway... That I really hope, but as of now I can't rule it out. I've tried with several Tomcat versions (4, 5, 5.5), all with the same result. But I'll give Jetty a try too..! However, all the objects that are lingering have some root going through some mbean-server and whatnot, and ends up in static fields of tomcat. Unless these instances also are held by my WebappClassLoader (which due to the names of the classes I tend to not believe; they seem so rooty), there is _something_ that in certain situations keeps some reference to some object of the webapp. But I'm not at the bottom of those objects yet. Remember that only _one single reference_ to _any_ object of the webapp will hold pretty much the _entire_ webapp from unloading: This is because each object holds a ref to its class, which again holds a ref to its classloader, which again holds refs to all classes loaded in the classloader, which again have static fields, which again probably holds a whole bunch of your actual objects. ThreadLocals as they are implemented in Java 1.4 and still, are apparently very dangerous for Servlet Containers, Tomcat included. ThreadLocals are implemented as follows: The Thread object contains a hashmap whose Entries have weak key and hard value. The key is the ThreadLocal instance, and the value is the actual referent (the object returned by threadLocal.get()). The ThreadLocal instance confers this map for finding its value for the current Thread. This can be done unsyncronized, since it's obviously singlethreaded (its a map within the Thread!). Thus, when a ThreadLocal instance goes out of scope, its key will be GCable, which due to the coding of ThreadLocal at some point later, hopefully, will release the value (it scavenges dead keys on subsequent sets (of any other TL instance)). Now, ThreadLocals instances are often declarder as a static (final), right? In situations where the ClassLoader is ditched, while the Threads are recycled, this _instantly_ creates an enourmous leak: The ThreadLocalMap instance within the Thread contains an Entry with a weak reference to the ThreadLocal static instance, and a hard reference to the value. The value has a hard reference to its ClassLoader. The ClassLoader have a hard reference to the Class that contains the ThreadLocal static instance - hence the key is still hard reachable, and thus the key won't be nulled and GC'ed - and thus again the Thread.ThreadLocalMap.Entry instance won't ever be scavenged, and the Thread will forever after contain a hard reference to the now-not-used ClassLoader. (- which as explained above holds all the WebApp's classes, which have static fields, which point to structures within your web application, and you're screwed). Check out Tackline's blog entry, which is the source of this information (I've hopefully understood his analysis!) http://www.jroller.com/page/tackline?entry=fixing_threadlocal This fine page also mentions ThreadLocals vs. Tomcat, but fails to point out that this should be viewed as a flaw with ThreadLocals: http://opensource2.atlassian.com/confluence/spring/pages/viewpage.action?pageId=2669 If you agree to this analysis, then vote for this bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6254531 ;-) Regards, Endre. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

copied into
CATALINA_HOME/war-deploy on the master node plus the other 3 nodes,
however
the webapp is not accessible.
The webapp has the distributable element as:

Is there something im missing - perhaps it something in the webapp

its just a hello world webapp with a single html file.
Any ideas appreciated!

Sharing classes between applications
Hi guys, I have a general question about sharing classes between two WebApps in Tomcat. In my case I have a Shop app and an now a new Admin app, which really can use lot of stuff allready implemented in the Shop. Of course copy-paste do work, but I supose copying-pasting after each update make no much sence... Well, what do you think, is this a good idea, to share the classes and if yes, how can I do it :) Btw, I mostly think of using my Hibernate persistance-managers there... not sure if it's even possible.

tomcat 5.5.15 - does JULI required a host tag defined realm?
I am in the middle of converting a web server from Tomcat 5.0.25 to 5.5.15, and I am using JULI. In the server.xml are three hosts defined, two of which have a realm defined in the host tag. The third has the realm defined in its ROOT.xml context tag. Each has a logging.properties file in its WEB-INF/classes directory. The third host (without the realm defined in server.xml) does not log to the file defined in its logging.properties file, though the file is created with a length of zero bytes. The logging information is output in the cataline.date.log file. If I move the realm definition from the ROOT.xml to server.xml, the logging occurs as expected (e.g. it is output to the file defined in logging.properties). It appears as if JULI requires a host defined realm? I hope I've explained the situation adequately. Does anyone have ideas of this? Is a realm in the host tag required for JULI?

Tomcat and mod_jk question on Red Hat 9
Hello, We recently setup mod_jk on a server running Red Hat 9. We are having some odd problems with the new setup. For some reason, everything works fine for the first 2 clicks when testing the process (running the examples webapp thru Apache 2.0.40). However, when we click something (anything, doesn't have to be the same steps) for the third time, it seems as though mod_jk cannot connect through AJP13 (Tomcat version is 4.1.29) . It trys to load for a long time and then nothing loads. If we wait for a bit and then do the same test again, the same thing happens. I can post more information and config settings, but I wanted to see if this is a common problem or not? We've had no problems running mod_jk in a Windows environment or Solaris in the past. If we need to post more information that is not a problem, we can do that. We talked to our hosting provider and they seem to think it's that we are running out of TCP Sockets? Any information would be great as we are trying to get a number of applications running on the server ASAP (of course). Thanks!

Re: tomcat 5.5.15 - does JULI required a host tag defined realm?
Hello Craig, In the server.xml are three hosts defined, two of which have a realm defined in the host tag. The third has the realm defined in its ROOT.xml context tag. Each has a logging.properties file in its WEB-INF/classes directory. Good, best chance to have individual logging for same loggers. The third host (without the realm defined in server.xml) does not log to the file defined in its logging.properties file, though the file is created with a length of zero bytes. The logging information is output in the cataline.date.log file. So the logging.properties of the third host has been read. If I move the realm definition from the ROOT.xml to server.xml, the logging occurs as expected (e.g. it is output to the file defined in logging.properties). It appears as if JULI requires a host defined realm? Does anyone have ideas of this? Is a realm in the host tag required for JULI? No, thats more a problem of the classloader. The logging config is per Context Classloader. So you can place a logging properties at any place in the classloader hierarchy. It seems that you have same the logging.properties in your webapp, but just changed the entry of the realm. Does the entry of the realm change the classloader (hierarchy) behaviour?

RE: Tomcat and mod_jk question on Red Hat 9
Adrian - I haven't met this problem, but a few things occurred to me after reading your message: 1. Don't forgot you could probably (depending on your config) always use mod_proxy instead of mod_jk, just as a temporary measure. 2. Sometimes browsers are set to have only 2 or 3 concurrent connections open to a server. Maybe something about your config - e.g. the resources being served up, or a mod_jk problem - means that the connections aren't properly closed, so on the third click it's actually your browser waiting until the other connections are closed. 3. It also sounds like a threading problem could cause these symptoms. Is there any 2- or 3-ness about the Tomcat config - e.g. the size of the pool of servlet instances maintained? Are the resources you're reaching when you click threadsafe? 4. Try looking in Apache's error log and in mod_jk's log (assuming you write one - JkLogFile directive).

Multiple HTTP GET from MS Word/Excel hyperlink
Whilst investigating a strange bug some of our customers were experiencing using links in Excel to our web application I discovered that the root of it was this strange behaviour in Excel. After monitoring the http requests I discovered that clicking a hyperlink in Excel creates the following multiple HTTP GET requests: -- GET /test.jsp HTTP/1.1 Accept: */* Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1) Host: localhost:8088 Connection: Keep-Alive Cookie: JSESSIONID=04E1A0B6BD7532F746F2BFCAE167422F GET /test.jsp HTTP/1.1 Accept: */* Accept-Language: en-gb Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1) Host: localhost:8088 Connection: Keep-Alive -- Notice the lack of JSESSIONID on the second request, this basically results in a new session being created and the previous session (and data) being lost.

GetRemoteUser() = null with apache 2.2 (not with 1.3)
Hello,
I've just found this message, with no solution, in the archive:
http://marc.theaimsgroup.com/?l=tomcat-userm=105163335014996w=2
It is exactly my problem:
I use apache authentification (basic) and the remote_user variable is
passing to tomcat. In a struts action i can get the variable with
HttpServletRequest.getRemoteUser(). Everything is ok with apache 1.3.33,
mod_jk 1.2.15 and tomcat 5.5.9.
I would like to upgrade my http server to apache 2.2 and i can't get the
remote_user (HttpServletRequest.getRemoteUser() == null).
I use the directive JkEnvVar REMOTE_USER %{REMOTE_USER} = no success
In my server.xml:
Connector port=8009 protocol=AJP/1.3 tomcatAuthentication=false
address=127.0.0.1/
Is there a solution?
Will i have more chance with mod_proxy_ajp?
Thanx,
Manu.

RE: Tomcat and mod_jk question on Red Hat 9
Sorry, Adrian - out of ideas, and Googling around for the error messages doesn't help much. I would certainly try updating mod_jk to the latest version, or recompiling from the version shipped with whichever Tomcat distribution you're using, all the while keeping your fingers crossed! However, it does feel more like a problem at the Tomcat end. If you are completely free to use whichever version of Tomcat you like, and you're already running web apps using 5.5.x, then you could try upgrading to 5.5.15, recently out of beta.

Boris,
I tried your logging.properties with the addition of the .handlers to no
effect.
On one of the other servers (where we use a custom realm) I moved the
realm into the ROOT.xml file - same affect (e.g. file created, but log
info goes to catalina.date.log).
Perhaps it's a feature. :-)

Re: mod_jk / 503 Error
So what makes you think you are not using localhost? Neal Whitley wrote: I have mod_jk / tomcat and apache somewhat working together but I am getting an error when displaying pages via the connector. Tomcat is set up and works. I can hit: http://www.site.com:8080/examples/ or http://www.site.com:8009/examples/ However, when I try: http://www.site.com/examples/ I get a 503 error. Service Temporarily Unavailable. The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later. What stands out in my mod_jk.log is this line: trying to connect socket 10 to 127.0.0.1:8009 The system seems to be trying to connect via the local host. As you can see from my config files below I do not reference localhost or the 127.0.0.1 IP address. Best I can tell JK should be using http://www.site.com:8009 to get/pass data to Tomcat from Apache. Is there a configuration option I am missing? Or how can I get JK to use the correct location?

Document Base on Network Drive
Dear all, To start, I am using Tomcat 5.5.12 on Windows XP Pro. I've been trying to configure Tomcat to read a document base on a network drive. However, I am seeing in the logs the error: java.lang.IllegalArgumentException: Document base M:\workspace\ir8\web does not exist or is not readable The document base works fine if I copy it to a local drive and alter Tomcat's configuration accordingly. However, I really need to do development on the network drive rather than a local drive. My domain user account has full permissions to this drive, and the path exists so I figured that I needed to get the service to run as myself (with the appropriate user policies). Therefore, I have tried the following: - set the Tomcat service to run as my domain user account - give my domain user account: logon as service, act as part of the operating system and replace a process level token privileges I have seen hints to this on many web sites (and it seems to make sense). Unfortunately, I am having no joy, and the error message persists. Ideas? -- Nige.

Re: How do I stop tomcat when the port is in use
Koneru, Narendra wrote: Hi, When the port that I specify to start tomcat is in use, then I want tomcat to go down after printing a message. What I observed is that tomcat prints the message on the screen that there is a bind exception but tomcat server does not go down. How do make sure that tomcat goes down after realizing that the port number is in use. I can't duplicate your problem. On Windows for me, running startup.bat twice activates TC on the first instance, but returns the error and closes the window for the second instance activation attempt (which would be using the same port). How are you starting Tomcat? What OS are you using? Glen - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Problem in tomcat configuration...
module not included in the server configurationthis is the key mod_jk is a third party module and is not in the apache distribution. It must be downloaded and compiled.

APR Connector Shutdown Problem
Title: Message I'm running into a problem with the APR connector not shutting down properly. Tomcat runs fine and there are no errors on shutdown, but if I shut Tomcat down and start it up again I geta socketbind failed errorin the catalina log (attached). I have to wait for several minutes between shutdown and startup for Tomcat to be able to startup correctly. If I run Tomcat without the APR connector, I don't have this issue. This does not occur on Windows, but does on Solaris and AIX. Has anyone else seen this? One thing I noticed is that the first thing logged on shutdown is an "AjpAprProtocol pause" entry, but there is no shutdown, stop or destroy. Is there any chance the APR connector is just getting paused and nothing is actually stopping it? Any help would be greatly appreciated.

I'd now like to host multiple instances of Tomcat (or maybe just multiple Tomcat connectors within one instance) to receive requests dispatched at multiple VirtualHosts on the same server. Is it possible to have more than one workers.properties file, and therefore more than one JkWorkersFile directive, per Apache? Ideally, I'd like one workers.properties file per VirtualHost just to make app-building easier.

tomcat logging from startup.bat

The end the startup script because of a ton of digester DEBUG log statements going to the console. Does anyone know what causes this?

Concurrently running tomcat and JBoss
Hello, has anyone had any luck in concurrently running two instance of tomcat together? What about an instance of JBoss and a stand alone tomcat? The reason why I need to do this is that some of the applications are conflicting with each other and cannot run together in JBoss. Since JBoss is still used for other apps, including apps that use the tomcat part of JBoss, the only solution I have is to concurrently run a tomcat instance. What ports will I need to change in order to avoid conflict with JBoss ports? The ports I plan to change are as follows: 8080 8443 8005 8009 8082 Would changing these values in the server.xml be enough? Last time I tried this, the shutdown script stopped working. Are there hard code values in the scripts? Any suggestions on how I could go about getting this to work? Thanks in advance. Regards, Khawaja Shams

So, open your standalone Tomcat's server.xml in a text editor, search for port= and for all the hits you get (at least if they're not embedded in comments), change the port's number to an unused value. That should be enough. BTW: if Tomcat complains about a port being in use, it isn't neccessarily another Tomcat instance that's blocking the port. netstat is your friend.

Weirdness in IIS log file - Tomcat serving up JSF pages
Hi; I have requests that are not getting logged. My setup is IIS 6.0 and tomcat where tomcat is called from IIS via an ISAPI filter. What the below log shows is: 1) /store/pages/demo.faces is requested. This is a JSF page served from Tomcat 2) demo.faces has includes for windward.css and windward.js - it shows them being requested. 3) The site next goes to demo_license.faces - but it never shows that request. 4) It then shows the requests for windward.css from demo_license.faces - so it did go to demo_license.faces. How can this be happening? demo.faces and demo_license.faces are served to IIS from Tomcat in the exact same way.

I'd been a Windows programmer back in the mid '90s and was curious to see how Visual Studio (it was Visual C++ back then) had evolved (or not). I didn't download Visual Studio but instead I downloaded a couple free tutorial videos for Microsoft's Web Developer Express product (which is a free product, BTW). Web Developer Express has a subset of the features in the full Visual Studio product and is used for building server-side (or client side, for that matter) web apps. I couldn't believe what I saw.

My impressions of C# vs. Java mirrored those of ASP.NET vs. servlets/JSP/etc. Java has kludgey support for properties and events (they're just regular methods with parameters) while C# has the constructs (delegates events) built directly into the core language. C# also supports co-routines, something we have to simulate in Java as well as out parameters (which allow a method to change the caller's parameter's value) and operator overloading. C# also has nullable types. Imagine Java's primitive types being able to hold null values. This is highly useful when working with databases. Finally, .NET provides an integrated and more comprehensive approach to setting security permissions and versioning of what are called, assemblies. Assemblies are very roughly equivalent to JARs. This allows you to compile your code against a specific version of an assembly and have that version information
RE: How can I take a webapp temporarily out of service using mod_jk?
Will mod_jk3 implement the AJPv13 Extension Protocol? That's what would best meet my requirements. What's behind my questions is that there's a short outage when I deploy a webapp on JBoss, particularly using farm deployment, where JBoss has to copy the war to all the machines in the cluster. I believe that the outage happens because mod_jk doesn't know that a webapp on one of the cluster servers is out of service (redeploying), so it doesn't direct traffic to one of the other servers which may have finished redeploying. If JBoss/tomcat can send status messages for individual webapps to mod_jk, this is possible.

Tomcat Manager behaviour difference between 5.0 and 5.5
Hi All, I had setup Tomcat 5.0.x in a school environment for students to write their servlet programs. With Listener className=org.apache.catalina.startup.UserConfig directoryName=public_html homeBase=/home userClass=org.apache.catalina.startup.HomesUserDatabase/ and some little scripts that make use of tomcat manager, all students can deploy/undeploy/reload their own application at their will. Recently, I was going to upgrade our Tomcat server from 5.0.x to 5.5.x and found that my little scripts were not alwyas working as they should suppose to. The reason I for this was, in Tomcat 5.0.x, when I call http://tomcatserver.edu/manager/deploy?path=/userwar=/home/user/public_html, it will create an XML file (user.xml) under $CATALINA_HOME/conf/Catalina/localhost, however, in Tomcat5.5x, it will actually COPY all files from user's public_html directory into $CATALINA_HOME/webapps/user directory. This behavior have 2 problems, this first one is my tomcat server's partition may not be big enough to hold few hundred students' servlet files. The second problem is the manager application will have exception if not all files in /home/user/public_html are world readable. The copying process simply stop without copying ALL files but manager application still got the OK and those students' servlet will have 404 error. My question is, are there any parameters for me to set so that Tomcat 5.5.x manager will behave just like Tomcat 5.0.x which only create an XML file when manger's deploy command executed?

Features comparisons for Tomcat (was Re: From Java to C#, ASP.NET [Off Topic])
It's kind of nice to see this discussion on this board, because it can serve as a way for Tomcat developers to think about what features really help and what features don't. I'm going to avoid M$ bashing cause it's not productive, but I think it's wise to look at the effect creature features have on product popularity and take note. My goal in continuing this thread under a new topic is to foster discussion about valuable Tomcat features. Hopefully it will spark some ideas about how to improve the popularity and appeal of Tomcat. I'll start with a short list of one relevant item. I encourage anyone to add to this, but please use the following format: TOMCAT FEATURE NAME/TYPE SUMMARY: description of the feature/issue RELEVANT INFORMATION: additional information IMPARCTED TOMCAT FEATURES: how Tomcat might be affected. SUGGESTIONS FOR ADDRESSING THE FEATURE: what can be done EASE OF USE SUMMARY: Some believe that the Microsoft web development experience is truely more pleasant than that of Java, and the often cite the number of people who have switched from Java to .NET platforms becuase of the percieved differences in ease of use. RELAVENT INFORMATION: On one hand, some people maintain that Tomcat is quite easy to use because starting and stopping the server requires the typing of a single command line. The counter argument to this claim is that a measure of ease of use should include all aspects of application development, deployment, and maintenance. For the purposes of discussion, ease of use for the Java platform and related Tomcat applications need to be clarified. Since Tomcat is built for the Java platform, we can view Tomcat ease of use as an extension of the concept of Java Platform ease of use. This will allow us to compare the overall Tomcat development experience with that of the Microsoft development experience. Unlike Microsoft development tools, which require the use of an IDE for efficient developemnt, the Java platform and related products (e.g. Tomcat server) make the use of IDE strictly optional. Consequently, a comparison between Java development and .NET development experiences cannot effectively be made by focusing on the steps required to build and compile a program. On the Java platform, the use of IDEs are strictly optional. Comparisons made between Microsoft IDEs and othe IDEs would more appropriately be restricted to the IDEs themselves, and not the platform. The fact that Microsoft has required the use of it's Visual Studio application to build and deploy application on the .NET platform complicates comparisons. The Microsoft development platform typically integrates the development tool with the server so that the developer clicks to deploy. This feature is not unique to Microsoft products, however. For example, Netbeans IDE integrates with Tomcat and provides many similar features to the Microsoft product set. This indicates the percieved differences in ease of use for may be an issue of user awareness about the available IDEs. While some prefer interacting with a development tool that requires less technical knowledge, others argue that such tools allow more room for less competent developers which can drastically reduce the overall quality of the end product. Furthermore, with the Java Development platform, the clear dilenation between the Java Runtime Environment, the Java Software Development Kit, and the optional IDEs give developers greater flexibility in building code, and the option to only install the development tools necessary. This capability is especially popular among those who are skilled in the development of applications using simple text editors, such as vi. Such developers argue that requiring the use of an IDE simply means more desktop software maintenance and upgrade issues. IMPACTED TOMCAT FEATURES: Maintainers of the tomcat platform so far appear to be finding a balance betwen developers with higher technical competencies and those who lean toward creature features. By providing a well published deployment interface and open source implementation, the Tomcat team leaves open the opportunity for integrated IDE development by others. Continuing to pursue this strategy will most likely ensure that a) the Tomcat development team retains flexibility down the road; and, b) gives competitors the opportunity to expend resources on features in their own products that don't ultimately increase sales for their product; and, c) caters to the development community with a higher degree of technical skill, which can produce web based application of higher quality. SUGGESTIONS FOR ADDRESSING THE FEATURE: Percieved differences in ease of use may be addressed through traditional advertising and a comprehensive marketing plan. - To unsubscribe, e-mail: [EMAIL
tomcat 5.5.15 jk1.2.15 connector problem apache 2.0.55
Hello, I am using the jk1.2.15 connector to connect the apache 2.0.55 webserver to tomcat 5.5.15 on a windows 2003 server. However, I am not getting any luck with the connector. I googled for hours on the internet, but nothing that matches. I even found contradictory information. In the docs it states that the workers should not be defined in the workers.list when you are using load balancing, but in the examples I found on the internet, they were defined in the workers.list (and yes I tried it but it just gives another error message).

Re: APR Connector Shutdown Problem
Fenlason, Josh wrote: I'm running into a problem with the APR connector not shutting down properly. Tomcat runs fine and there are no errors on shutdown, but if I shut Tomcat down and start it up again I get a socket bind failed error in the catalina log (attached). I have to wait for several minutes between shutdown and startup for Tomcat to be able to startup correctly. If I run Tomcat without the APR connector, I don't have this issue. This does not occur on Windows, but does on Solaris and AIX. Has anyone else seen this? One thing I noticed is that the first thing logged on shutdown is an AjpAprProtocol pause entry, but there is no shutdown, stop or destroy. Is there any chance the APR connector is just getting paused and nothing is actually stopping it? Any help would be greatly appreciated. Thanks in advance. I suppose you have: Listener className=org.apache.catalina.core.AprLifecycleListener / in your server.xml But of course it doesn't guarantee it will be executed in all cases, if the JVM crashes for example. On Solaris it can take up to 4 minutes until the OS recycles the zombie socket. You can use: ndd -set /dev/tcp tcp_time_wait_interval 6 To lower that value. APR does not try to fool the OS like JVM, but rather behaves like Apache httpd. Regards, Mladen. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: tomcat 5.5.15 jk1.2.15 connector problem apache 2.0.55
Ok, My mistake. I mixed the examples in the source file the wrong way. But now it gives me the same error as when I try to configure it without load balancer: [Fri Jan 27 08:24:52 2006] [1532:3412] [debug] jk_uri_worker_map.c (475): Found a wildchar match wlb - /*.jsp [Fri Jan 27 08:24:52 2006] [1532:3412] [debug] mod_jk.c (1839): Into handler jakarta-servlet worker=wlb r-proxyreq=0 [Fri Jan 27 08:24:52 2006] [1532:3412] [debug] jk_worker.c (111): found a worker wlb [Fri Jan 27 08:24:52 2006] [1532:3412] [debug] jk_worker.c (301): Maintaining worker wlb [Fri Jan 27 08:24:52 2006] [1532:3412] [debug] mod_jk.c (531): Service protocol=HTTP/1.1 method=POST host=(null) addrr=10.1.227.76 name=ntbrawebdv11.braine.ucb port=9080 auth=(null) user=(null) laddr=10.1.4.244 raddr=10.1.227.76 [Fri Jan 27 08:24:52 2006] [1532:3412] [error] mod_jk.c (1932): Could not init service for worker=wlb [Fri Jan 27 08:26:31 2006] [1532:3828] [debug] mod_jk.c (1761): Shmem cleanup [Fri Jan 27 08:26:31 2006] [1532:3828] [debug] mod_jk.c (1761): Shmem cleanup [Fri Jan 27 08:26:31 2006] [0264:3124] [debug] mod_jk.c (1761): Shmem cleanup I'd really like more details in the logs why it can not initialize the worker. But I guess debug is all I'm going to get. I checked the system event logs as well, but no luck either (syntax errors in the workers.properties are logged over there though). I assume my tomcat config is ok since it works with the older jk2 connector. The AprLifecycleListener is only needed in case of automatic configuration, but maybe this is a specific issue to win 2003? Luc Carpentier Luc (Uniway) wrote: I even found contradictory information.
