That just made the trick! Please, can you explain me how those changes affects? Each Apache process has a private connection pool associated with each AJP13 worker. The size of the pool is determined automatically during startup. By default it is set to the number of threads in the process. You decided to overwrite the pool size to 1 :( The connection_pool_size attribute is only needed for other web servers like IIS or Sun/Netscape, because we can't determine a useful pool size automatically for them, Please read the explanation of connection_pool_size on http://tomcat.apache.org/connectors-doc/reference/workers.html Where did you get the value 1 from? Regards, Rainer Thanks for the explain Rainer. May be I just misunderstood the last paragraph at the description of connection_pool_size: Do not use connection_pool_size with values higher then 1 on Apache 2.x prefork or Apache 1.3.x!

Re: Tomcat 6 unstable
I highly doubt Tomcat is unstable. If anything, your webapp is unstable. Is your tomcat install from the Ubuntu distribution or from Apache Tomcat's website? I tried to create the folder CATALINAHOME/common/lib (version 6 brings no folder) and there copying the jar needed. Folder structure changed from tomcat 5.x to 6.x. Tomcat 6 only has $CATALINA_HOME/lib and it should already have all that's needed to run except maybe your db2 jdbc driver. I tried editing the setclaspath.sh, since in the first few lines, what it does is literally erasing the entire class that has ... Well, there was a CLASSPATH = and it changed by a CLASSPATH = $ CLASSPATH, this way it is not deleting the old value of the variable. Don't ever change the classpath. You are asking for worlds of pain and suffering with strange, near impossible to trace errors. Put this back the way you found it. java.lang.NoClassDefFoundError: javax/servlet/http/HttpServlet Can you describe the circumstances around this more? Was it from within Eclipse? Did you move servlet-api.jar from $CATALINA_HOME/lib where it belongs? java.lang.NullPointerException org.apache.jsp.query_002dadd_002d2_jsp._jspService(query_002dadd_002d2_jsp.java:107) In your JSP, you are trying to access properties/methods of a null object.

Apache 2.2.3 with mod_jk 1.20 loosing connection with a cluster of two Tomcat 6.0.10
Hello, My application server running Apache HTTP Server 2.2.3 as a front end with mod_jk 1.20 to transfer request in AJP to a cluster of two Tomcat 6.0.10 instances is getting Connecting to tomcat failed. errors within the mod_jk logs on a random basis. The whole cluster runs on a Windows Server 2003 Release 2, which is itself a virtual machine running under VMWare ESX 3.2. The cluster runs applications for an intranet and some specific users accesses it via the extranet. The whole thing is not public on the internet. The whole cluster can run properly for a week and then going down as much as three times in the same day. I assume this is not traffic related since the issue occured at times of day where no one is at the office (very early in the morning). When this happens to the first instance of Tomcat, the second one goes down seconds after. Restarting Apache HTTP server nor Tomcat services fixes the issue. I need a complete reboot of the server. I cannot see anything relevant in the Tomcat logs. However, in JConsole, when it occurs I can see the total threads of both tomcat instances rising up to 1000 (it normally floats aroung 200 / 250 total threads) even if the number of active threads stays the same (150). As if threads were created/deleted/created... and so on very quickly. There is a strange behaviour: When it occurs, obviously I cannot access the applications via Apache HTTP server since it says Service Temporarily Unavailable but if I try to access directly both Tomcat on their HTTP connector, pages shows but with incomplete parts, sometimes pictures are missing, sometimes HTML is incomplete. I assume this is a Tomcat issue since the threads are going berserk, but I am unsure at this point. No need to say that my goal is to prevent all of this from happening...

RE: Apache 2.2.3 with mod_jk 1.20 loosing connection with a cluster of two Tomcat 6.0.10
Hello Peter, Thank you for your suggestions. I forgot to say that even if there is two Tomcat instances running behind an AJP connector, no load balancing has been enabled. Each Tomcat contains its own set of applications. -Original Message- From: Peter Crowther [mailto:[EMAIL PROTECTED] Sent: 24 novembre 2008 09:52 To: 'Tomcat Users List' Subject: RE: Apache 2.2.3 with mod_jk 1.20 loosing connection with a cluster of two Tomcat 6.0.10 From: Éric Gauthier [mailto:[EMAIL PROTECTED] [...] I assume this is a Tomcat issue since the threads are going berserk, but I am unsure at this point. [... good description elided...] Thanks for a comprehensive description of the problem. It *may* be an application or environment issue, especially as both app servers fail at nearly the same time. Common mode failures such as this could indicate: - Shortage of memory on the server causing OutOfMemoryException, after which anything could happen! I didn't see any OutOfMemoryException in Tomcat logs. - If your application uses other resources (such as a database), is the database doing anything unusual at around these times? Suddenly long response times, down for maintenance, or similar? Yes they use the same database resource. I will check if anything occurs at this time with the database. - If the app is an Internet application, is one of the web crawlers suddenly hitting it with a massive load and saturating it? I tried to perform a suddent massive load with JMeter and the only thing it caused (I may have abused on the concurrent requests) is an OutOfMemoryException and then both Tomcats stopped responding. But this is not what I am actually experiencing... - Is the virtual machine being starved of resources at these times due to something else happening on the host? The VM is dedicated to webapp hosting. No other VM has the possibility to steal resources to this VM. But to make sure, I will check the resources usage logs for this VM the guys in charge of that. All just vague ideas at this point, and I suspect you have already considered and rejected them! - Peter - 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]

Re: failure notice
Not sure what you mean by platform Independence here but OCI driver is just a type two? JDBC driver that provide superior performance. You will have to install an oracle client into your system but this shouldn't be a big deal is it ? We have developed some financial app two years ago and we settled on using that native driver after couple of performance tests ... as far as I can remember, it was also necessary if you have oracle stored procedure and packages that might need recompilations while the web app is running ... if you use the pure java connection pooling, the pooled connections are no longer valid and you will have to restart the server or figure out away to get rid of all connections in the pool.

My apologies if the english i write sounds rude, but i am not very good with english or Tomcat neither :D - I speak spanish, so don't be mad with me, specially Antonio Petrelli. -- Answering to Hassan Schroeder: Thanks for your answer Hassan. Specifying when and how Tomcat doesn't work for me: 1) The servlet loading problem happens when I startup Tomcat, manually, as I always do, showing the exception: java.lang.NoClassDefFoundError: javax/servlet/http/HttpServlet java.lang.ClassLoader.defineClass1(Native Method) java.lang.ClassLoader.defineClass(ClassLoader.java:620) java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124) java.net.URLClassLoader.defineClass(URLClassLoader.java:260) java.net.URLClassLoader.access$000(URLClassLoader.java:56) java.net.URLClassLoader$1.run(URLClassLoader.java:195) java.security.AccessController.doPrivileged(Native Method) java.net.URLClassLoader.findClass(URLClassLoader.java:188) java.lang.ClassLoader.loadClass(ClassLoader.java:306) sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:276) java.lang.ClassLoader.loadClass(ClassLoader.java:251) org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1273) org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1204) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:263) org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:584) org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) java.lang.Thread.run(Thread.java:619) And when I shutdown Tomcat and then startup it again, only sometimes my servlet is loaded. In other times, Tomcat load my servlet perfectly, just doing the same. 2) When the first problem does not happen, the http session works unproperly, and some attributes of the session are made null, in this case, Tomcat throws the NullPointerException, but if I reload the jsp everything is ok. Files with the source code of the servlet (Login.java), a jsp and the connection class (works in a package called peerca) are attached. - Answering now to Matthew Chamber, and giving thanks for the reply: 1) About the web.xml: I include the web.xml file in the attachments. 2) About an earlier Tomcat: I just downloaded the 6.0.18 version and catalina.sh it's running ok (but I have not put my webapp there yet). 3) About the db2 jdbc driver, well, it is allocated in many paths... JAVA_HOME/jdk/jre/lib/ext/db2jcc.jar CATALINA_HOME/lib/db2jcc.jar CATALINA_HOME/webapps/cqaex/db2jcc.jar CATALINA_HOME/webapps/peerca/WEB-INF/lib/db2jcc.jar DB2_HOME/V9.5/java/db2jcc.jar ¿Can this cause troubles? Where exactly I need to put this file, taking into account I need driver be avalaible for other java aplications, not only for tomcat webapps? 4) About using war file: I am not using any war file, I just use the folder with the name of the app put it into webapps. 5) About running Tomcat as root user: can this cause troubles too? Do I need to running it as the common user? What kind of properties (chmod) does the CATALINA_HOME need to work in many users without running as a root? Answering David Smith: thanks for the reply. I am using the binary version 6.0.14 available on Tomcat website, but Matthew recommended me to use an earlier one, the 6.0.18. This one I will use from now go on. I am not using any Eclipse, I just write manually my codes and the follow the folder structure of a webapp into webapps folder. Servlet api is where you said, as always does: into CATALINA_HOME/lib. About the nulls: yes, I already check for null values before use it, but is like the session delete it from nowhere, without reasons. --- Now I just try with the 6.0.18 and I will put my webapp there. The only error is with DB2 connections, although the session has the connection, this is not null but when i tried to list the tables some error happens: -- com.ibm.db2.jcc.b.nm: DB2 SQL Error: SQLCODE=-204, SQLSTATE=42704, SQLERRMC=DB2INST1.AM_BASE_TASKS, DRIVER=3.50.152 at com.ibm.db2.jcc.b.wc.a(wc.java:579) at com.ibm.db2.jcc.b.wc.a(wc.java:57) at com.ibm.db2.jcc.b.wc.a(wc.java:126) at com.ibm.db2.jcc.b.tk.c(tk.java:1901) at com.ibm.db2.jcc.b.tk.d(tk.java:1889) at com.ibm.db2.jcc.b.tk.a(tk.java:1416) at com.ibm.db2.jcc.t4.db.g(db.java:138) at com.ibm.db2.jcc.t4.db.a(db.java:38) at com.ibm.db2.jcc.t4.t.a(t.java:32) at
Tomcat 5.5.2 Configurations for JSESSION ID Cookie Append
Tomcat Users: I'm working with a current session identity issue between separate browser instances, and have decided that the most plausible solution is to reconfigure tomcat to auto-append the JSESSION ID at the end of each URL. The only problem is, our system administrator cannot seem to dig up this information over the internet. I have not dug deep into the issue, but I trust his judgment, and thought I would send a note to the subscription line to see if anyone is familiar with the server.xml configuration change that needs to occur to enable this feature. I appreciate the assistance and apologize for any inconvenience. Regards, Jonathan

I have a Tomcat 6.0 Web application with a number of buttons on the screen. Some of them execute quickly, some more slowly. However, they need to execute in order. When a user clicks on a slow button and then clicks on a fast button Tomcat needs to wait for the results of the slow button before moving on to the fast executing button.

Re: User Request Ordering
Clifton B. Sothoron Jr. wrote: I have a Tomcat 6.0 Web application with a number of buttons on the screen. Some of them execute quickly, some more slowly. However, they need to execute in order. When a user clicks on a slow button and then clicks on a fast button Tomcat needs to wait for the results of the slow button before moving on to the fast executing button. However, this is not happening. The results of the fast button are disrupting the results of the slow button. How do I configure Tomcat to process user requests in order? You can not, and this has nothing to do with Tomcat per se. I would say that this is a case of a badly-designed user interface. It should not be possible for the user to click several buttons, if the result is so that it might cause trouble in the application. You need to control that at the user interface level, which means in the html page itself (or applet, if that is what you use). The inappropriate buttons should be disabled (and visibly so for the user), and only enabled when it is legal for the user to click them, in other words when the response from the previous logical action has been received. At the most, what any HTTP server (Tomcat being one of many) could do, is to keep some track of a user session, that would allow an application, at the server side, to notice that some pre-requisite for the current request has not been met (like, this other action that should have been done before, has not been done yet), and return an error to the user. But that would be quite difficult for the user to understand, in addition to loading your application with invalid requests. It would be more logical to prevent this at the source, no ? (In fact, for security and reliability you need to do both, and not absolutely rely on a user-side page that can be manipulated). - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Setup Logging for Tomcat 6
To setup log4j, here's what I did.
Copy the log4j jar file to WEB-INF/lib. Put it in ${catalina.home}/lib if you
want all webapps to be able to see this file.
Create a log4j.properties. Initially this file was in
WEB-INF/classes/log4j.properties. Now I have the file in
WEB-INF/lib/myjarfile.jar!log4j.properties (that is, at the root level of the
jar file).
That's it, if I remember correctly.
When the properties file specifies a relative filename, it appears to be
relative to ${catalina.home}, so specify for example logs/myfile.log.

I will forward your response about upgrading tomcat to the appropriate team, however we are only using tomcat internally so I do not believe it's a major concern.

Monitoring Tomcat with Jconsole
Hi. I lied in the subject. This is not strictly a question about Tomcat monitoring, although the ultimate aim is to monitor a specific Tomcat application. But I'm trying to start small first, and I'm encountering a problem with Jconsole, for which this is my first-ever try. I have a java stand-alone application (daemon) running on host myhost under Linux on a Sun JVM 1.5. It's a kind of network server, listening on port 11100. I started this application with the following parameters : ./java -Dcom.sun.management.jmxremote.port=11200 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.password.file=/mydir/ management.jmxremote.password -Dpgm=STARXMLServer -jar /home/star/xml/STARXMLServer.jar The file management.jmxremote.password contains this line at the end: monitorRole mypass On the other hand, I run Jconsole on a Windows XP station, using a Sun Java 1.6 JVM as follows : java version 1.6.0_06 Java(TM) SE Runtime Environment (build 1.6.0_06-b02) Java HotSpot(TM) Client VM (build 10.0-b22, mixed mode, sharing). When I use the New connection dialog to specify that I want a remote connection with Host:port : myhost:11200 userid : monitorRole password : mypass then the dialog disappear for a few seconds, then comes back, with an error message at the very bottom saying : Connection failed: Connection refused: connect (Note : this Jconsole can monitor its own JVM when using the local process choice) So, what am I doing wrong ? One think I noticed, is that on the server myhost, despite the daemon application being loaded without any apparent error messages, and being responsive to requests on its own port 11100, a netstat -an does not show any port 11200 in a LISTEN state. I do not know at this stage if this is significant. My understanding is that it is the JVM on the myhost system that should listen for connections on that port 11200, not the application itself, right ? Nor can I think of any system-level reason why the system would be rejecting incoming connections on port 11200. This is a local network, and there is no firewall or anything between the Windows workstation and the myhost host.

The JS-Wrapper should have no effect on the built-in tomcat logging. It (js-wrapper) can only log its self.

What I meant above was the apparent disproportion between the 266M number and what (I think) I see really used by the application according to jconsole. But from you comment above, I gather that I was wrongly fixated on that number (266M) and that it does not really represent any real memory used in any permanent way by the process.

Committed memory: 2.452 kbytes Increased due to heap expansion plus probable enlarging of the code pool, C heap, PermGen, etc. Nothing unexpected here. Ok. Now a final question on this app : By running the requests that lead to the snapshot 2 above, I believe I have pretty much stressed that app as much as I can (they were relatively heavy requests, involving a fair amount of XML parsing). After watching jconsole for a while, I noted that the total heap space used always remained below 8 Mb, and the non-heap space remained below 9 Mb at all times. So, I have incrementally brought down the value of some switches, to this level : -server -Xms16M -Xmx32M -Xmaxjitcodesize16M without apparently having any effect on the application's ability to process requests. My idea in doing this was to reduce the amount of system memory this application maybe reserves for no benefit, and thus leave more real RAM for others. Considering the numbers above, in your opinion is there anything I could/should still try, while still leaving a margin for the application to support maybe a higher level of requests ? I am not looking for definite answers here, just trying to get a feel for the stuff, what is important or not. Like for instance if you told me to never touch this -Xmaxjitcodesize, that it doesn't bring anything and could crash the application and cause all my hair to fall off, or anything along those lines. The point is, after that I'm going to go through the same kind of exercise with Tomcat, and I want a feel for what I should or should not play with.

Copy the log4j jar file to WEB-INF/lib. Put it in
${catalina.home}/lib if you want all webapps to be able to
see this file.
You really don't want to put the log4j.jar into Tomcat's lib directory
unless you actually want all the webapps to *share* (not just see)
the same logging complex.
See the driver - I think I used that expression yesterday. Share a

From: André Warnier [mailto:[EMAIL PROTECTED] Subject: Re: Monitoring Tomcat with Jconsole I gather that I was wrongly fixated on that number (266M) and that it does not really represent any real memory used in any permanent way by the process. Correct; it's analagous to profit claimed by certain financial institutions... What really matters is the Resident part of it (23M), as compared to how much physical RAM the system really has Yes, but be wary of how big the Java heap can get. One normally runs server programs with -Xms == -Xmx, partly to avoid any chance of the heap growing and running into page thrashing. How big the new + old can get, if needed. And can be controlled by the -Xmxsize switch, yes ? Correct. By running the requests that lead to the snapshot 2 above, I believe I have pretty much stressed that app as much as I can (they were relatively heavy requests, involving a fair amount of XML parsing). Depends on whether or not the app is capable of processing multiple requests concurrently (like Tomcat and most servers can). My idea in doing this was to reduce the amount of system memory this application maybe reserves for no benefit, and thus leave more real RAM for others. It's useful to size the heap appropriately, balancing GC frequency against RAM usage. I wouldn't mess with the max code size attribute - let the JVM use what it needs; the rest won't get any pages allocated to it anyhow. Considering the numbers above, in your opinion is there anything I could/should still try, while still leaving a margin for the application to support maybe a higher level of requests ? I'm not really in a position to say - I have no real feel for what this particular app needs when the going gets tough. Best for you to continue to monitor it, preferably in a production environment if you can (as well as doing your own stress testing, of course). Like for instance if you told me to never touch this -Xmaxjitcodesize, that it doesn't bring anything and could crash the application It probably provides no benefit, and could cause the app to run slowly if the JIT doesn't have enough room to store all the generated native code, causing recompilation of methods. It's not likely to cause a crash, but I suspect the main purpose of that option is to stress test the JIT. and cause all my hair to fall off If it hasn't done so by now, that's probably not a concern. (I've still got mine.) The point is, after that I'm going to go through the same kind of exercise with Tomcat, and I want a feel for what I should or should not play with. The main thing to adjust is the max heap size. Fiddling with the other stuff will buy you a lot less than streamlining your webapp code. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

I haven't looked inside log4j to see just what information in maintains in static fields or singletons, but keeping the log4j.jar with each webapp insures you won't get any unwarranted interaction in your webapps' logging. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

You said you've manipulated Tomcat's startup script. Don't do that. Make a clean install and it should work. 2) When the first problem does not happen, the http session works unproperly, and some attributes of the session are made null, in this case, Tomcat throws the NullPointerException, but if I reload the jsp everything is ok. This sounds like something in the session isn't properly initialized. I'd say this is an error in your application. 2) About an earlier Tomcat: I just downloaded the 6.0.18 version and catalina.sh it's running ok (but I have not put my webapp there yet). Careful! :-) 3) About the db2 jdbc driver, well, it is allocated in many paths... JAVA_HOME/jdk/jre/lib/ext/db2jcc.jar Placing the driver here makes it available to everything run via this JVM, including Tomcat and your web applications. CATALINA_HOME/lib/db2jcc.jar Placing the driver here makes it available to both Tomcat and all web applications. It allows you to use the connection pool with this driver. CATALINA_HOME/webapps/cqaex/db2jcc.jar Placing the driver here makes it available for download in the cqaex web application. CATALINA_HOME/webapps/peerca/WEB-INF/lib/db2jcc.jar Placing the driver here makes it available only to the web application peerca. It is (a) redundant when the driver is already placed in CATALINA_HOME/lib, and (b) won't allow you, on its own, to use the connection pool. It only allows you to load the driver via the DriverManager. DB2_HOME/V9.5/java/db2jcc.jar This is probably the place of the driver in the DB2 distribution. Won't hurt. ¿Can this cause troubles? Where exactly I need to put this file, taking into account I need driver be avalaible for other java aplications, not only for tomcat webapps? If you want to think of Tomcat as independent of the JVM you run it with, place the driver in Tomcat6/lib or reference it from Tomcat6/conf/catalina.properties. 5) About running Tomcat as root user: can this cause troubles too? Do I need to running it as the common user? What kind of properties (chmod) does the CATALINA_HOME need to work in many users without running as a root? It's not considered good practice to have a service run as root when there is no need to do so. The root user is very powerful, so it's potentially dangerous expose a process run as root to the world. Tomcat should probably be run as www-data or whatever it is called on your system. All permissions issues can be handled by using chmod and chown. I don't know your particular situation, but it's unlikely you have to resort to running Tomcat as root. I am not using any Eclipse, I just write manually my codes Very good! So you don't lose the ground under your feet. Now I just try with the 6.0.18 and I will put my webapp there. The only error is with DB2 connections, although the session has the connection, this is not null but when i tried to list the tables some error happens: -- com.ibm.db2.jcc.b.nm: DB2 SQL Error: SQLCODE=-204, SQLSTATE=42704, SQLERRMC=DB2INST1.AM_BASE_TASKS, DRIVER=3.50.152 Sounds like an SQL error to me. Look it up in your IBM manual. at com.ibm.db2.jcc.b.wc.a(wc.java:579) at com.ibm.db2.jcc.b.wc.a(wc.java:57) at com.ibm.db2.jcc.b.wc.a(wc.java:126) Reasonable package names. Got to get an IBM database, too. at java.lang.Thread.run(Thread.java:619) --- and this error did not happen in the older version... any ideas? Where the db2jcc.jar needs to be, to be available for all my applications in java (not only in Tomcat). Read this: http://mail-archives.apache.org/mod_mbox/tomcat-users/200811.mbox/[EMAIL PROTECTED] Short answer for Tomcat 6: Either put the driver in $Tomcat/lib, or add it to the common.loader in conf/catalina.properties. The idea I have is to create a pool of connections. I read the concept but now I need to implement it. Is Tomcat deal with the pool or I need to ask help in DB2 forums ? It'll probably work the same way as for other database servers. In order for this to work, both Tomcat and your webapp need to be able to see the driver. I hope this helps.

Classes loaded from Tomcat's lib directory are shared at runtime by all webapps (and Tomcat, for that matter), whereas classes coming from a webapp's WEB-INF/lib or WEB-INF/classes are local to that webapp. If the classes from Tomcat's lib directory have any static fields or singleton objects, only one copy of those fields and objects exist for all the webapps. I see. I wasn't aware of this property of the common.loader. Does the same hold true for the shared.loader? I haven't looked inside log4j to see just what information in maintains in static fields or singletons, but keeping the log4j.jar with each webapp insures you won't get any unwarranted interaction in your webapps' logging.

Re: Re: Tomcat 6 unstable
Hello Tomcat World! Thanks Chuck and Michael. This is the answer for Michael:
That's like you find out your car has no wheels. You said you've
manipulated Tomcat's startup script. Don't do that. Make a clean
install and it should work.
Yes, I did, a complete clean installation of Tomcat 6.0.18. I downloaded and
put it into the /opt directory. Then, I edit the catalina.properties, wich has
the following sentence:
common.loader=${catalina.home}/lib,${catalina.home}/lib/*.jar
I read the link you posted me, but the comments in the catalinal.properties has
no example with file:/// so I did not write like this. I added to this line
the path to the db2 jdbc driver. The current sentence is this
one:
common.loader=${catalina.home}/lib,${catalina.home}/lib/*.jar,/opt/java/jdk/jre/lib/ext/*.jar
¿Is this right or do I need to include file:///?
2) About an earlier Tomcat: I just downloaded the 6.0.18 version and
catalina.sh it's running ok (but I have not put my webapp there yet).
Careful! :-)
I did that because one of you recommend me to do that. Why do you say careful?
Is this a bad practice? Should I use the startup.sh ??It's not considered good
practice to have a service run as root when
there is no need to do so. The root user is very powerful, so it's
potentially dangerous expose a process run as root to the world.
Well, in this
new phase of using Tomcat, I am not running it as root, just as common user
and it's working fine, but the DB2 connection deal is still causing me troubles.
Thanks for all. Now I need to learn how to do a pooling of connections. Any
comments?
I really apreciate your time for answer me.

Don't do that - put it back the way it was. The DB2 driver classes will be

No, you don't need the file:/// prefix; but in any case you don't want to
change the loader config at all.

For normal running, use the startup.sh script; for easier debugging, use
catalina.sh since it runs Tomcat in the same window as the shell you're using

RE: Re: Tomcat 6 unstable
From: Michael Ludwig [mailto:[EMAIL PROTECTED] Subject: Re: Re: Tomcat 6 unstable This is starting to sound like DLL Hell. A bit, but the advantage of a classloader hierarchy is that webapps are isolated from each other (a servlet spec requirement). If you keep the jars your webapp needs with the webapp and not scattered all over, you won't have a problem. Unfortunately, you can't do that if you want Tomcat to manage the DB connection pooling, since Tomcat itself must have access to the JDBC driver classes. You can always manage the pool inside the webapp yourself using commons-dbcp or the like. Could web app Foo, which brings its own DB2 driver - in spite of the same driver already offered by the common.loader or the bootstrap.loader, by this very fact jeopardize other web applications running in the same container, which rely on the DB2 driver offered by the common.loader? Or would web app Foo only harm itself? Good question, and it doesn't have a clear answer. If an object originating in a webapp classloader is passed to code from a more global classloader, and then another webapp accesses that object, it will not be castable to any type the second webapp has access to. (Class myPackage.MyClass loaded by classloader A is not the same type as myPackage.MyClass loaded by classloader B.) Does this mean web apps have to be monitored for the classes they make available in order to make sure none of them has already been made available via the common.loader? If a webapp minds its own business, there shouldn't be a problem. If it tries to use Tomcat's DB connection pooling (or logging, or some other shared mechanism), but insists on providing its own copy of the shared classes, then there are likely to be problems. (This is a problem with servlet containers - not just Tomcat - because it breaks the standard Java classloading model of always delegating upwards. As mentioned before, this breaking is pretty much required by the servlet spec.) - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

DB2 problem: AM_BASE_TASKS ¿is a ghost table?
I know this is not a DB2 list, but certainly the problem is between Tomcat and DB2, because everything doing manually, with DB2 terminal, using a console, is working properly. I am using a java connection class and a JDBC driver : db2jcc.jar for developing a webapp in Tomcat 6.0.18 on Ubuntu 7.10. I am connecting, querying and updating without problems using the same user, the same driver and even the same jsp pages to connect many DB2 databases. All of them are running locally, with the exactly same conditions and owner, in my laptop, and they are working properly. But there is a single one, called cafe. I put some OUT.PRINTLN for debugging and know what was going on. The problem is when I tried to retrieve the tables from the schema, and then selecting all of each table. I also print its names, as I do with the rest of dbs, an exception happens, and the output of Tomcat showing me a table that is not existing in the reality of the schema. I am really surprised of this, as a newbie of DB2... Although, in the db2 console, everything seems to be normal, showing me the 8 tables there are in fact exists. ¿Why Tomcat throws me an exception and shows me this ghost table called AM_BASE_TASKS.
