Re: Cluster Not Syncing After Restart
Hi David, you can't restart your nodes so quickly. As you shutdown one node you must wait 30-45 sec before next restart. Don't restart both nodes at same time.

Re: Tomcat 6 embedded use - problems with jsp - No Java compiler available
Hi, I found a first hint on my own - it is probably related to setting-up jasper correctly - but I hope someone can tell me how to set the parameter for jasper in embedded mode. What I did was: // Create a handler for jsps Wrapper jspServlet = context.createWrapper(); jspServlet.setName(jsp); jspServlet.setServletClass(org.apache.jasper.servlet.JspServlet); jspServlet.addInitParameter(fork, false); jspServlet.addInitParameter(xpoweredBy, false); jspServlet.setLoadOnStartup(2); context.addChild(jspServlet); context.addServletMapping(*.jsp, jsp); context.addServletMapping(*.jspx, jsp); But it seams not enough for embedded mode. I think I have to set also classpath , compiler ,compilerSourceVM , compilerTargetVM. But I do not know where to point them in embedded mode ??? Is there somebody who can help me on this ?

I agree it will take time, i have 64MB of ram. I guess dotnets ability to compile on install would be useful here... i don't think there is an equivalent for java especially 1.4.2 that I am running. Has there been any progress on that in recent times ? If there is that would be great... I notice that on running it is causing a lot of swapping to occur, my swapping process is using a lot of time.

Re: How can I speed up and reduce load of initialization
How big is your Java heap? And how much of your 64MB is used by other (non-Tomcat) processes? If Tomcat is causing a lot of virtual memory swapping, it *may* help to decrease the size of the heap so it fits into main memory. But that may make the heap too small, so garbage collection becomes a problem or Tomcat runs out of memory entirely. It depends on how much free memory you have and how much Tomcat + your app needs. -- Len On Jan 17, 2008 5:12 AM, Gavan Hood [EMAIL PROTECTED] wrote: I agree it will take time, i have 64MB of ram.

Tomcat 6 - Cluster error.
Hi,
I repost the problem with a better subject:
We had a tomcat 5.0.28 server configured with 2 clustered instances(working
perfectly), and we decided to migrate to java6 and the new tomcat 6.0.14.
We modified the configuration files to match the new tomcat 6.0.14
structure.
But now we have really annoying problems with the cluster.
This server receives aprox. 1 petition per second. We have pen as the load
balancer between 2 instances.
Once started, both nodes report member.added and they are clustered.
Works fine. I can restart any node and no session is lost.
But around 12 days after being started, instance number 2, report a
cluster.member disappear, then the session replication doesn't work,
instance 2 is unstable and gives a timeout error (But instance 1 is still
alive!!).
So we have to reload both nodes every 12 days.

Re: Automatic Thread Dump configuration
En l'instant précis du 17/01/08 15:46, Chad Kellerman s'exprimait en ces termes: Tomcat Users, I have been googling Tomcat thread dumps and have not seen what I want to accomplish anywhere... Is there a way to configure Tomcat to execute a thread dump whenever there is an Out Of Memory issue or if an app reached the max thread count? When there is an OutOfMemory, it's impossible to make a ThreadDump. The reason is that, since you lack memory, it can be seen as useless to try allocating StackTrace object and stuff it in a new Error(). Moreover, from my experience, when you are out of memory, the location where you are out if generally irrelevant, as it's most of the time cause by a memory leak somewhere else. As for you max ThreadDump, you could still try feeding the tomcat output to an external tool that sends a Kill -3 to tomcat Thre when it sees some keyword. Note that, in both cases, it's not tomcat's job to make a ThreadDump, it's more related to jvm behaviour. Other vendors than sun might have some facilities for that?

New jsp not being read
Hi all, Here is my environment: Eclipse Europa Tomcat 5.5 Windows XP Pro My application goes like this: request -- servletA -- form.jsp -(post)- servletB My problem is this: when I make a change to form.jsp, this change is not reflected in the jsp that gets displayed. An older version of the jsp is displayed. I have checked path specified in my servlet to make sure it's poitning to the right jsp. In fact, the version that's displayed doesn't exist in any of my folders, so I'm not sure where this form would be coming from. I've had this result using IE and Firefox. I thought it might be an Europa issue, so i tried running the app on Eclipse 3.2 - same result. Cleaning and rebuilding the project makes no difference. Also, it doesn't seem possible anymore make a change to the servlet, and have it hot deployed. I don't get a message from Tomcat saying it couldn't hot deploy, but in order to make the modified version of the servlet current I need to do a Clean/Rebuild of the project. Everybody's thoughts on this would be greatly appreciated!! Thanks.

RE: how to communicate between different tomcat servers
1) You may want to consider JBOSS or GLASSFISH (Which ever one supports clustering better). This is the best done utilizing full blown J2EE servers. This is why JEE was created in a first place. Tomcat should be used by your front end tier. Good luck. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, January 17, 2008 12:00 AM To: users Subject: how to communicate between different tomcat servers hi, all I build a web application based on tomcat. In my design, I devide the server side into several separate logic parts,and each part is deployed on a separate Tomcat server. e.g. the first tomcat server is to process login request, second tomcat server is to calculate user data, the third tomcat server is to store all the user information. It is a distribute architecure, and I hope in this way, this system can be extended by adding tomcat server when the application load on one Tomcat server is big enough. For example, when the second tomcat server's calculation work is too big, I can add a new Tomcat server to do calculation work, so do the first Tomcat server for processing login, while in the system, there is only one Tomcat server to store the total user information. This architecture is widely used in the Client/Server mode application, while I'm not sure whether in Browser/Server mode it can work. I think this requirment is different to the Tomcat cluster, because Tomcat cluster can solve the load balance problem, while in my case, I would like to keep some global data on one Tomcat server such as the third tomcat server. So currently, I meet a problem of how to communicate between the tomcat servers, I think http or webservice can do this work simply, but the efficiency is not good, and I don't know whether JMS is a good choice for this. I wonder if there is any other way to communicate between the tomcat server? Can tomcat servers work in such a distribute way? Any help and suggestion will be welcome.

I've found that working (on my dev box -- sometimes windows, sometime linux) under Eclipse, it can be somewhat unpredictable when redeployment of a new page really takes in Tomcat's directory. When it seems funny, as Chris suggested, I shutdown Tomcat (from the MyEclipse control). Since I often have several apps I'm currently working on (myapp1, myapp2, ...), I just remove the specific Tomcat folders for, say myapp2: ~webapps/myapp2 and ~work/myapp2, then redeploy from the MyEclipse control., and then restart Tomcat.

already replied to your old thread ok, it looks like you might have ended up with a rogue socket, and what happens is that any message sent to that socket just gets lost in the ether, since it doesn't have any interest ops.

An older version of the jsp is displayed. I have checked path specified in my servlet to make sure it's poitning to the right jsp. In fact, the version that's displayed doesn't exist in any of my folders, so I'm not sure where this form would be coming from. I've had this result using IE and Firefox. I thought it might be an Europa issue, so i tried running the app on Eclipse 3.2 - same result. Cleaning and rebuilding the project makes no difference. Also, it doesn't seem possible anymore make a change to the servlet, and have it hot deployed. I don't get a message from Tomcat saying it couldn't hot deploy, but in order to make the modified version of the servlet current I need to do a Clean/Rebuild of the project. Everybody's thoughts on this would be greatly appreciated!! Thanks.

RE: How can I speed up and reduce load of initialization
Normally compilers are the memory hogs! A few things you can do is that; 1. If you use JSP, convert to servlets to avoid initialization phase compiling. 2. If your JDk is JIT (Just in time) compiler enable, disable it. You may have a bit slow execution. But should have satisfactory speed. 3. Increase memory size! I use 512MB and dual CPU. Still initialization taking significant time! Gavan Hood wrote: I agree it will take time, i have 64MB of ram. ...

life span for Tomcat 5.5.x and 6.0.x ?
I was wondering if there's any sort of planned end-of-life date for when security patches will no longer be provided for Tomcat 5.5.x and 6.0.x ? We're upgrading from 5.0.x and I want to make sure we don't have to upgrade again for a while (ideally not until sometime in 2009). Thanks - Ray

Nothing is certain since it all depends on how much effort the release managers are able / want to put in. That said, as the RM for 4.1.x I see security fix support continuing for at least 2008. Beyond that? Depends if there is any sign on the users list of people still using it. I still see the odd message from a 4.1.x user and it isn't as if doing around a release a year is taxing. 5.5.x has around 100 open bugs that are slowly getting fixed. My guess is that these will be fixed in the next 12 months and then 5.5.x will move to releases only when there are security fixes. Bugs will probably still get fixed as well, but maybe not. 6.0.x will continue for a while. There are plans for a 6.2.x that will have some very minor API changes but, since they are API changes, we will call it 6.2.x. When this will happen? Don't know. Because the API changes are so minor and the upgrade path trivial for 99.99% of users then there is a small chance we will stop all support for 6.0.x at that point and move to 6.2.x. What actually happens will depend again on what people want to do, the size of the API change and if they think the effort of continuing to maintain 6.0.x is worth it. We're upgrading from 5.0.x and I want to make sure we don't have to upgrade again for a while (ideally not until sometime in 2009). I would go (and have gone) with 6.0.x, accept that there may be a change to 6.2.x but that you can almost certainly treat it like to 6.0.x to 6.0.x+1 upgrade. If this isn't the case then it is almost certain 6.0.x support will continue. Bear in mind I am only one committer. The others may have very different views but I suspect their recommendation will be the same - go with 6.0.x.

Ordered loading of WAR files
Hi, I have two war files. One is an authentication war and the other is setup to use the authentication war via the servlet context.xml mechanism. On windows my issues appears to be that the context.xml from the auth.war is being cached inside tc/conf/Catalina/localhost/... and that on the 2nd startup it tries to test the connection before the war that is the connection has loaded. I've solved this temporarily by deleting this directory before startup. Does anyone know of a better way to do this? I am using tomcat 6014.

Thanks! After changing no-cache to cache, it worked! But I am not sure whether this may deliver the same documents when diiferent documents are generated. The another problem was that inline didn't work for JSP urls, say, .../mydoc.jsp. So I have to use a servlet taking JSP as parameters and use RequestDispatcher. It works properly now. Regards.

Re: PDF problem on IE from JSP
The critical part of my solution (which I got from someone else's post) is the setting of the cache stuff. Setting the mime type is something you have to do and my particular case depends on the filename type, but as long as it gets set you also need to set the cache right as well.

RE: Custom initialization after startup
From: Jonadan [mailto:[EMAIL PROTECTED] Subject: Custom initialization after startup Is there any way I can perform custom initialization IMMEDIATELY after Tomcat startup automatically? Depends on what you mean by IMMEDIATELY. You'll at least need to insure that the Host attribute deployOnStartup is true (it is by default), and that you implement a ServletContextListener for each webapp of interest. Read section 10 of the servlet spec for details of the latter. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: Custom initialization after startup
I need to start database before any servlet gets first request. So immediately after server start, initialize embedded database and make it ready for incomming first requests, of course, in a separate thread. The same goes not termination time. I need to have control passed immediately after all working servelts destroyed so that I can terminate database system NORMALLY! Currently it dies suddenly with Tomcat and every new starts starts with emergency recovery! Smooth normal shutdown is preferred. Regards.

RE: Custom initialization after startup
PS: Yes, it can be done with ServletContextListener since we can check whether it is alive or not. However we may not sure whether it is system shutdown or app. shutdown. This is quite tricky. DBMS can use huge heap resources up to over 500GB on larger systems. This can be a problem without knowing the entire server is going down!
