Help needed with Tomcat 5.5.7 admin app (MBeanServer is not available)
Simon,
I had the same problem. Then I discovered that the admin app had to be
installed under ${Catalina.home}/server/webapps rather than just
${Catalina.home}/webapps. Once I moved the directory to where the Context
docBase said it was supposed to be, it started working.

Subject: Help needed with Tomcat 5.5.7 admin app (MBeanServer is not

Hi there,
I've just installed Tomcat 5.5.7 (using the .exe installer on WinXP)
and, whilst the server and manager app work fine, I'm having problems
with the optional admin webapp.
I downloaded the admin zip file and extracted the files to the
appropriate locations. The admin app starts ok and I can log in, but
when I click on Environmental Entries (or try to add a datasource),
I get a 500 response with the message MBeanServer is not available
(stack trace from stdout log below).

Admin app fails with MBeanServer is not available
I've searched the mailing list archives, and the net at large, but I haven't seen anyone report this problem for Tomcat 5: I downloaded and installed Tomcat 5.5.4, and version 5.5.4 of the Admin webapp. The Admin webapp starts up fine, but when I click on the Environment Entries button in the Admin webapp, I get the error message which I've appended to this email. I've tried downloading various incarnations of JMX jars, and putting them in various Tomcat folders, as some archived messages recommended for this problem under Tomcat 4.x, but to no avail. Is this a real bug, or am I just doing something wrong?

RE: Adding DataSources to a specific webapp context using MBeanServer - Success (using a custom tag)
Hi all, I found a way to create some DataSources in a webapp context from a properties file, at tomcat startup. I did it by creating a custom tag that I will add on the entrance page. For information, doing it from a struts plugin also works if you create the DataSources in the _Global_ context (only). If somebody achieve to do create DataSources in the webapp context from a struts plugin, plz share your magic.

RE: Adding DataSources to a specific webapp context using MBeanServer - half success
Hi all, Could anyone tell me the order of the initializations of the webapps contexts, the webapps, the servlets (those run at startup). I succeeded in creating my DataSources in my webapp context by redeploying my classes with tomcat running, I just copied the newly compiled classes to the WEB-INF/classes directory, and tada! The datasources appeared in the admin webapp. It works but the problem is not solved as I did it by hand. I'll explore the way of making it recompiled automatically by another webapp which name alphabetically follows my webapp's name and is therefore deployed after. But I would prefer a less dirty way.

MBeanServer in Tomcat 5.0.10
Hi, As mentioned in the changelogs of Tomcat version 5.0.10 MX4J 1.1.1 is being replaced by JMX 1.2 RI Please refer to page http://jakarta.apache.org/tomcat/tomcat-5.0-doc/changelog.html for details. Has any one tried out to get the MBeans in this new implementation ? I am trying to get the MBeanServer and access the MBeans exposed by Tomcat. Any help in this direction will be deeply appreciated Santosh Click onthe image to chat with me
Re: How to get reference of MBeanServer in Tomcat
You need to have the JkCoyote connector running (even if you are using
Tomcat stand-alone), and in your $CATALINA_HOME/conf/jk2.properties file
add:
mx.port=9000
Of course, change '9000' to whatever port you want the JMX consol to listen
to.
Note: There is a bug in Tomcat that is doesn't shutdown the consol properly
if you use this option. As a result, you will lose the ability to do a
clean shutdown.

Hi Purvis,
Thanks for the reply.
This code will give me the MBeanServers on the same

But in our case we want to get the MBeanServer of a
remote Tomcat. The Tomat server may be running on any
other machine. I would have the port number and the
address of the machine where the Tomcat is running. So
the problem is to get MBeanServer of this Tomcat.
Do we have any APIs for doing this?

Re: How to get reference of MBeanServer in Tomcat
I am trying to get the reference of Tomcat MBeanServer
I am using the folowing code :
---
RemoteMBeanServer server;
IIOPConnector con = new IIOPConnector();
String protocol = http;
String host = 192.168.0.15;
int port = 7080;
String path = ;
JMXAddress address = new JMXAddress(protocol, host,
port, path);
Hashtable props = new Hashtable();
props.put(Context.INITIAL_CONTEXT_FACTORY,
javax.naming.InitialContext);
props.put(Context.SECURITY_PRINCIPAL, admin);
props.put(Context.SECURITY_CREDENTIALS, );
con.connect(address.getPath(), props);
server = con.getRemoteMBeanServer();
---
Classes RemoteMBeanServer and JMXAddress are from
mx4j.connector package.
I dont now what value we should give for
Context.INITIAL_CONTEXT_FACTORY
And also JMXAddress constructor takes a String
parameter path. I dont know what exactly this means.
Has any one tried this out. Is this the proper way for
getting MBeanServer reference. If anybody has tried it
please get me a sample code for this.

Re: How to get reference of MBeanServer in Tomcat
For (now somewhat outdated) security reasons, Tomcat ships the jmx jar in server/lib so that it is only accessable to Tomcat internals (and trusted webapps like 'admin'). It should be enough to move the jar to common/lib to get access to the JMX server. You may also have to move the commons-modeler.jar to common/lib as well (don't know for sure, never tried :) s p [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] I am using JMX technology to get information of Tomcat server.

Re: MBeanServer Fails - Admin Tool Won't Work
I don't see what it has to do with Windows. It also has nothing to do with missing JMX jars. The mx4j-jmx.jar is in the TOMCAT_HOME/server/lib directory along with its license file, as it should be. There doesn't appear to be anything wrong with the installation exe. But thanks for the thought, Bill. Any other possible explanations for this mystery? - MOD --- Bill Barker [EMAIL PROTECTED] wrote: I'm not a Windows user myself, but it looks like you are missing the JMX jars.In your %CATALINA_HOME%\server\lib their should be either a 'mx4j-jmx.jar' or a 'jmxri.jar'.

StandardContextValve exception starting MBeanServer
