2 servlets on tomcat.
Hi I have installed tomcat v6 on port 8080, wrote a simple java program (eclipse 3.7) and now i have my servlet running. now i want to write another servlet, how can i define tomcat so that i can run both servlets at the same time? or maybe it is not possible. Thanks a lot.

Using namespaces within XML documents produced from JSPXs
Hi there, I'm trying use taglibs with a JSPX page, but also specify a namespace declaration for elements rendered by the JSP. An example: foo:xyz xmlns:foo=path/to/foo/ns xmlns:bar=path/to/bar/ns foo:p/ bar:q/ /foo:xyz In the above example, I have a taglib registered for only 'foo', whereas I'd like 'bar' to be considered verbatim and added to the body content as such. What actually happens is the xmlns declaration is removed and is not made available to the taglib component processing 'foo:xyz'. Jasper then complains that 'bar' is not bound. I've also tried: jsp:root xmlns:jsp=... version=2.1 xmlns:foo=path/to/foo/ns foo:xyz xmlns:bar=path/to/bar/ns foo:p/ bar:q/ /foo:xyz /jsp:root But again the 'bar' namespace is removed. I also tried 'jsp:attribute', although that appears to strip the namespace off the element completely, despite http://java.net/jira/browse/JSP_SPEC_PUBLIC-97 stating that namespaces would be supported in version 2.1. I'm lost and can't think my way around this one unfortunately, any help *vastly* appreciated. Regards, Paul

My question is, why my first aproach didn't work ?

What version of specification is specified at the top of your web.xml file? Just a quick test with current trunk of Tomcat: Using the standard examples application that comes with Tomcat. I edited the following page: \webapps\examples\jsp\jsp2\jspx\textRotate.jspx 1) I replaced opening svg tag with: svg xmlns=http://www.w3.org/2000/svg; width=450 height=500 viewBox=0 0 450 500 xmlns:c=http://java.sun.com/jsp/jstl/core; xmlns:fn=http://java.sun.com/jsp/jstl/functions; xmlns:jsp=http://java.sun.com/JSP/Page; xmlns:foo=bar jsp:directive.page contentType=image/svg+xml / titleJSP 2.0 JSPX/title foo:xBar!/foo:x Note xmlns declaration and foo:x element. The page, http://localhost:8080/examples/jsp/jsp2/jspx/textRotate.jspx?name=JSPX renders correctly and gives me: ?xml version=1.0 encoding=UTF-8? svg xmlns:foo=bar xmlns=http://www.w3.org/2000/svg; viewBox=0 0 450 500 height=500 width=450titleJSP 2.0 JSPX/titlefoo:xBar!/foo:xg id=testContent() With correct xmlns:foo=bar and foo:xBar!/foo:x. 2) But if I move xmlns declaration from svg element to the new jsp:root element (adding it around the document): jsp:root version=2.2 xmlns:jsp=http://java.sun.com/JSP/Page; xmlns:foo=bar svg xmlns=http://www.w3.org/2000/svg; width=450 height=500 viewBox=0 0 450 500 xmlns:c=http://java.sun.com/jsp/jstl/core; xmlns:fn=http://java.sun.com/jsp/jstl/functions; jsp:directive.page contentType=image/svg+xml / titleJSP 2.0 JSPX/title foo:xBar!/foo:x (...) /jsp:root It generates invalid XML document where the foo prefix is not declared: svg xmlns=http://www.w3.org/2000/svg; viewBox=0 0 450 500 height=500 width=450titleJSP 2.0 JSPX/titlefoo:xBar!/foo:xg id=testContent (...) So, from practical point of view, I think that the problem is the following: - jsp:root tag by definition does not generate any content - your custom tag can only generate text (from Tomcat perspective) Thus it has no XML element in its possession to set xmlns attribute on it. (Nor it is clever enough to add xmlns attribute to some other element, as in the example of svg document it does not add it to the svg element). I think the cause for this behaviour might be that the generated xml document can be included as a part into another xml document (with jsp:include) and thus there should be a mechanism to suppress unneeded xmlns declarations.

Seeking tips on multi-host, multi-context deployments
Hi, folks. I've got what I consider to be a fairly significant production implementation of Tomcat with, currently, 89 contexts in 30 hosts on two concurrent servers. Everything works fine ... except when it doesn't. As the number of contexts and hosts have increased, there have been more and more JVM and/or Tomcat crashes, typically a couple per week lately, on one or both servers. The error messages vary from nothing at all in catalina.out, to exceptions regarding database connections, to exceptions about threads. Basically, I've been trying to find some good advice on configuration in my situation and haven't been able to find much. In a bit more detail, the deployment is as follows: (2) Dell 1950 8-CPU servers running Fedora 14 Linux 2.6.35, one with 2 GB RAM and one with 4 GB RAM (2) Tomcat 7.0.16 instances, one on each server, running clustered contexts in distributable mode, under Sun JDK 1.6.0 One server runs Apache HTTPD, using mod_proxy_ajp to connect to the two Tomcat instances and manage balancing The other server runs PostgreSQL, the database used by the apps, which connect to it via JNDI/JDBC connection pooling There are a few contexts that run on only one or the other server (namely, Softslate and Searchblox, which are not serialized to support clustering). Most contexts, which run my app, run in parallel on both servers. I've implemented clustering to maintain site availability when a Tomcat instance goes down. I could post up all the various JVM and Tomcat parameters, but I'm really looking for any definitive list of tips for things to try to improve stability. If anyone has written or seen a how-to document on multi-host, multi-context deployments like this, please share! Thanks!! P.S. One option I've considered is to run KVM and run each host in its own virtual OS. To me that's a ridiculous amount of OS overhead to deal with occasional Tomcat outages, but it probably would be one solution, much more difficult to maintain than a single Tomcat instance per server running all the hosts and contexts. If you've had experience running multiple Tomcat instances in separate virtual machines, I'd be curious to hear how it went. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Most contexts, which run my app, run in parallel on both servers. I've implemented clustering to maintain site availability when a Tomcat instance goes down. I could post up all the various JVM and Tomcat parameters, but I'm really looking for any definitive list of tips for things to try to improve stability. If anyone has written or seen a how-to document on multi-host, multi-context deployments like this, please share! Thanks!! P.S. One option I've considered is to run KVM and run each host in its own virtual OS. To me that's a ridiculous amount of OS overhead to deal with occasional Tomcat outages, but it probably would be one solution, much more difficult to maintain than a single Tomcat instance per server running all the hosts and contexts. If you've had experience running multiple Tomcat instances in separate virtual machines, I'd be curious to hear how it went. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Without the specifics of the execution environment and the observed errors, it's really impossible to give you anything definitive. More RAM is often useful, but frequently only postpones outages due to ill-behaved applications (the most common cause of crashes). - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

I fixed the missing message r1176477. The rest of the issue needs investigation. Last changes in the shutdown code were http://svn.apache.org/viewvc?view=revisionrevision=1065945 Fixed in trunk and 7.0. It wouldn't be in 7.0.22 which is already tagged, but in 7.0.23. Proposed for 6.0.

Re: catalina_pid file contains +1 pid number instead of correct pid

You should read http://tomcat.apache.org/security-6.html as well as all the fixed issues in changelog. I have recently enabled catalina_pid functionality using environment variable. The PID file got created and contains +1 PID number. If the Tomcat's real PID number 5446, the pid file would contain 5447 as PID number. catalina.sh is a shell script file. There are not many secrets there and it is editable. You should try to debug what really goes on on your system. IIRC there were some talks about using exec command vs eval command in the script to launch the process. Anyway, if CATALINA_PID file were not working I think somebody would report it, but 6.0.20 was so old ago and I do not remember such reports. Please help me to resolve this problem as we are using tomcat in 10 of our servers. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org Actually the PID number in the PID file is not wildly incorrect.
