I seem to remember something like that on debian... Anyway... on windows heap space and that stuff doesnt show you much... its the handles that we watch... And why they useful... is that as soon as heavy load comes off... those handles quickly recover, if they dont, you leaking ;) In your case the old heap is filling... and in theory that old heap should only hold long lived objects (so mel tells me).. ie things like a xml parser and that sort of stuff... the eden should be rising and falling like a yoyo, and the old heap should stable out... Anyway... if you can just find the equive of task manager handles on your linux... its easier to watch.

Re: Tomcat vs Weblogic JNDI Lookup
The * was just a wildcard for the example. Fill it in with whatever you like. Let's say we have a datasource named appds So code deployed to WEBLOGIC can do this: context.lookup(appds); While code deployed to TOMCAT must do this: context.lookup(java:comp/env/jdbc/appds); That is my problem and I can't 'adjust' the way they are build in Weblogic. I believe, the Weblogic admin is simply going to the web admin console for Weblogic and simply creating a datasource connection and giving it a simple name. Whereas, if I declare this datasource in tomcat's server.xml ... context tag ... the deployed code always needs to preprend the lookup name with java:comp/env. I'd like one Spring config file or Source code file that did the right thing depending on whether or not it was deployed to Tomcat or Weblogic ... Hope that makes sense. -Luther On Sat, Sep 6, 2008 at 4:41 PM, Martin Gainty [EMAIL PROTECTED] wrote: if you use a JNDI lookup with a declared namespace such as xmlns:jee=http://www.springframework.org/schema/jee; more specifically in the case of spring http://www.springframework.org/schema/jee/spring-jee.xsd where jndi-name is declared to be xsd:attribute name=jndi-name type=xsd:string use=required xsd:annotation xsd:documentationThe JNDI name to look up./xsd:documentation /xsd:annotation /xsd:attribute which can then reference a specific jdbc resource supplying provided jndi-name of jpetstore-order such as jee:jndi-lookup id=orderDataSource jndi-name=java:comp/env/jdbc/jpetstore-order/ I dont know what specific resource you are trying to locate with wildcard nulls we might be able to help out better if you could explain your specific testcase HTH Martin __ Disclaimer and confidentiality note Everything in this e-mail and any attachments relates to the official business of Sender.

For development (localhost), we might be running Tomcat and when declared in the context section of server.xml, Tomcat will hang JNDI datasources on java:comp/env/jdbc/* in the JNDI tree. *Problem:* in Weblogic, the JNDI lookup is appds whilst in Tomcat, it seems that that I must provide the formal java:comp/env/jdbc/appds. I'm afraid the Tomcat version is an implicit standard but unfortunately, I can't change Weblogic's config ... so that means we end up with two different spring config files (we're using spring 2.5) to facilitate the different environments.

Re: [NEWBIE]Tomcat 6.0.16-reboot required when changing the port number
1.I´ve updated server.xml to change the default port from 8080 to 80, however, I´ve noted that restarting the server leaves apache tomcat listening on both ports 8080 and 80, until the server is rebooted. Are you stating that you have to reboot twice? Are you sure that it's tomcat that is still listening on port 8080? Try the shutdown script then run the command netstat -anp | grep 8080 as root. If nothing comes up then that is a good thing. You may end up having to post your server.xml is the problem persists. Scripts executed shutdown.sh startup.sh OS: RedHat Fedora 9 running Linux 2.6.25 2. It´s also noted that exporting the following line, makes the server crash (i.e. Gnome does not boot up and some libraries seem be corrupted during startup) export LD_ASSUME_KERNEL=2.4.1 Why? Most likely because you are running kernel 2.6 and trying to force some apps to think you are running 2.4. This will cause libc problems. Why are you doing this? Tomcat doesn't require you to do this. -Steve O. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I have to say that I have yet no experience with configuring IIS with Tomcat, so the following are somewhat theoretical findings. Maybe, if the following won't help you, you can repost your question mentioning IIS in its title, and properly describing all components of your configuration. Also, you may try searching on how to access tomcat root application through IIS. Here is what I have found: 1) http://tomcat.apache.org/tomcat-5.5-doc/catalina/docs/api/org/apache/j k/ config/IISConfig.html It is some Tomcat class that writes IIS configuration files for you (e.g. as the initial configuration of the server). Note the noRoot configuration attribute. If you examine the sources of that class, you may note, that root context (ctxPath equals ) have some special processing. That includes the following comment: # Note: To correctly serve the Tomcat's root context, IIS's Home Directory must # must be set to: \ + getAbsoluteDocBase(context) + \ May be that is what you are missing? Somehow I cannot not find any mention of root context specifics in the tomcat and tomcat connector documention and wiki. 2) The following two articles might be useful: http://www.iisadmin.co.uk/?p=8 http://blogs.msdn.com/david.wang/archive/2005/10/14/HOWTO_IIS_6_Reques t_ Processing_Basics_Part_1.aspx I did not read them through, though.

Its actually difficult to imagine a site built using just using TC technology having a single url, its got to be coming from one major control servlet that even does things like include static content and ajax is used incorrectly. I tend to agree with this guy for instance... http://www.webpronews.com/expertarticles/2006/11/21/ajax-and-search-engines Ajax or XMLHttpRequest can use a post, but I've never used it that way, for the most part is always a get on our stuff? Whether public or private I think anyone should be thinking about the possibility of indexing their site. I dont think its impossible at all to make a cookie driven site search engine friendly, but it doesnt seem be happening... Without even taking technology, if one minute the content behind a url is cars for sale, and the next minute its top sales man of the year, how do you index that? And if a user is wanting to pull TC apart to get at Vary: ETags... wonder why that is... maybe another single url site got em ;) Anyway that all I'm saying because I think after 6 months of hard work and design if developers do find themselves in this position, its a real gotcha... Probably can be avoided or done correctly in any framework... but they getting caught... thats all I'm trying to say to developers, because once there, how do you help them?

Re: Default application or HTML redirect
I am sorry, but can you summarize, what is not working at this moment? What computers, where in the network, are involved in the case that is not working? In this thread several questions were raised. a) How to make an application the default one. Answer: The default application is named ROOT (case sensitive). You should undeploy the default one (delete webapps/ROOT, webapps/ROOT.war, conf/localhost/ROOT.xml), rename your war file to ROOT.war and deploy it. Using the manager application you can verify, whether the deployment was successful. But it seems that it was, because you can access your application without MyApp path. Also, as far as I understand, at this moment you have deployed your application twice, as ROOT.war and as MyApp.war. Note, that the manager application displays a name for each application, that name is configured in display-name element of web.xml. Thus, you can see, whether your application is the root one, and not the Tomcat's default one (Welcome to Tomcat is the name of the one that comes with Tomcat). b) IIS is not used at the server. c) When accessing the server from a client computer, using its external IP address of the server, the application is accessible without MyApp path. d) If, accessed from the same client, using DNS name of the server, default Tomcat ROOT application is displayed. If that is the case, then you should check that it is actually accessing your server, and not some other computer. Check that DNS name is being resolved correctly, as you are expecting. 1) with nslookup Windows command, 2) check the contents of file %SystemRoot%\system32\drivers\etc\hosts - the IP address can be overwritten there. Check the route to the server (tracert). If there is network address translation (NAT) and/or port mapping involved, check configuration of the router (proxy) that performs the translation. Maybe your ISA is that proxy, and I am not familiar with how it is being configured. Try accessing the manager application through the server name. If request reaches the server, it can be processed differently if virtual servers are configured, but in your case - Tomcat configuration does not have virtual servers (we have seen that from your server.xml), - You have undeployed the default ROOT application (you can check that through the manager application), thus there is no way that the default Tomcat page can be displayed by this instance of the server. What is the configuration of your ISA? How your publishing the server through it is configured? So, what is not working?

Well, the file is the same as the default one, only connector port number is changed, s/8080/80/ Do you have manager application installed? Usally it is installed. If yes, you can add user username=foo password=bar roles=manager/ to your conf/tomcat-users.xml, and access the application by the http://localhost/manager/html/ It will list all the applications that are deployed, and allows you to undeploy applications and deploy your war file by uploading it.

Re: Tomcat loops indefinitely
Well, I do not know what DefaultSparqlDispatcher actually is, but googling found the following source code of it: https://submarine.computas.com/sublima/tags/0.9.5/blocks/sublima-query/src/main/java/com/computas/sublima/query/impl/DefaultSparqlDispatcher.java Thus, the following line: SettingsService.getProperty(sublima.joseki.endpoint); is the address to where it opens an HttpURLConnection. What is that address? Judging from the behavior, it occurs that it makes request back to itself. Best regards, Konstantin Kolinko 2008/9/5 Kjetil Kjernsmo [EMAIL PROTECTED]: Hi all! I'm struggling with a really weird problem. I have a Cocoon 2.2 application that runs on Tomcat 5.5.25-5ubuntu1 and Java 1.5.0. My (semi-)production system, my test system and my development system are Ubuntu 8.04 boxes, and they differ very little, with the exception that the production environment is a Vmware slice, the others are not. The application runs fine on the development and test systems, but it is not at all working on the production box. What's happening is that I deploy the war, restart the server. I then GET a URL on the system, apparently, any URL will do. The application starts doing its thing. In my log, I see messages like http-8180-Processor230 DEBUG impl.DefaultSparqlDispatcher - SPARQLdispatcher connected to Joseki. http-8180-Processor229 DEBUG impl.DefaultSparqlDispatcher - SPARQLdispatcher connected to Joseki. http-8180-Processor228 DEBUG impl.DefaultSparqlDispatcher - SPARQLdispatcher connected to Joseki. which my application emits.

Re: question : encounter java.net.SocketTimeoutException: Read timed out occasionally

Re: Tomcat 6 and corruption of text in French error pages
2008/9/6 André-John Mas [EMAIL PROTECTED]: Hi, I have Tomcat 6 installed on a French version of Windows XP. When error pages, such as the 404 error page, appear the French text is corrupted. For example, instead of the expected: La ressource demandée (/manager/html) n'est pas disponible. I get: La ressource demand�e (/manager/html) n'est pas disponible. This would appear to indicate that the page is being encoded as UTF-8 and then treated as ISO-8859-1. The display is consistent in all browsers I have tested with, which include IE6, Safari and Firefox. Has anyone seen this and do they know how to resolve it? I know I could simply use my own error page, but that is not the answer I am looking for, 1. What, exactly, Tomcat version are you using? 2. Does Content-Type header of the response contain the ;charset=utf8 suffix? You can check that using LiveHTTPHeaders firefox plugin, or using wget --save-headers, or connecting through telnet. In my case, the Content-Type: of the 404 page is text/html;charset=utf8, and the browser (Firefox 3) correctly detects that the page encoding is UTF-8.

Re: Good JSP editor
2008/9/6 sam wun [EMAIL PROTECTED]: If you are using a good jsp editor, can you tell me where its download link? My current development enviornment is Eclipse 3.4 and Tomcat 5.5.26 What are you expecting from a good one? You know, tastes and requirements may differ. Eclipse already has an JSP editor. I mean, the JEE developer's edition of Eclipse. Our developers are using it and have no significant complaints. Well, some older versions could corrupt the page code (loosing characters) when reformatting it, but that was a year ago. I do not know such complaint about the current one. Also, there are still some issues when correct code is highlighed as if it were wrong. Usually I leave JSP validation disabled for the build time. There are some other web development plugins for Eclipse, that predate the Web Standard Tools WST/JST project (e.g. MyEclipse), but I do not know what is their status now. Some of them might be more mature than WST/JST.

UnauthorizedAccessException error while running WMI in tomcat
I have written the following code in Java to access registry of a remote
machine. I am able to execute the program successfully when i run the
program separately. But when I try to execute the code in Apache Tomcat. I
am getting
UnauthorizedAccessException error.The full text of error is

machineName) at BOMInfoCollector.BOMInfoCollector.getOSVersion(StreamWriter
file, String remoteName)
Following is the Java code: try { String keykey =
C:\\Diagnostic\\DiagnosticAssayRE\\Executable\\BOMInfoCollector.exe;
String ipadddress = Remote machine's IP; String keyStr1= keykey + +
ipadddress;
Process p = Runtime.getRuntime().exec(keyStr1);
BufferedReader stdInput = new BufferedReader(new
InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new
InputStreamReader(p.getErrorStream()));
// read the output from the command
while ((s = stdInput.readLine()) != null)
{

}
while ((s = stdError.readLine()) != null)
{
response = response + s +\n;
System.out.println(s);
}}catch(Exception e){
System.out.println(Exception occured +e);
}
Following is the C# code whose name is

Console.WriteLine(You are not authorized to access the machine.Please check
the network Privileges +e);
}catch(Exception e){
Console.WriteLine(Error occured +e);
