Suzann,

Sure, maybe something like this (formatting my be skewed on BEA's NewsWeb site)...


<%@ page session="false" %>

<%= new java.util.Date().toString() %>

<%
String s = null ;
try
{
s = java.net.InetAddress.getLocalHost().getHostName();
out.println("Weblogic Hostname: "+ s + "
");
}
catch ( Throwable t ) {}
%>

Then, throw it into a WAR file (w/ deployment descriptors, of course) and deploy
to your cluster. Should be good to go.

You could use this bit of JMX code, which I use. If you get load
balanced across a cluster, this will show which managed srever you're
actually attached to.

Hope it helps,
Pete

This bit goes in the top of the jsp

<%
weblogic.management.runtime.ServerRuntimeMBean server = null;

try {
weblogic.jndi.Environment env = new weblogic.jndi.Environment();
javax.naming.Context ctx = env.getInitialContext();
weblogic.management.MBeanHome mbeanHome =
(weblogic.management.MBeanHome)ctx.lookup(weblogic .management.MBeanHome
LOCAL_JNDI_NAME);
java.util.Set mbeanSet =
mbeanHome.getMBeansByType("ServerRuntime");
java.util.Iterator mbeanIterator = mbeanSet.iterator();
while (mbeanIterator.hasNext()) {
server =
(weblogic.management.runtime.ServerRuntimeMBean)mb eanIterator.next();
}
} catch (Exception e) {
%>

Error trying to get MBEAN Reference for local server:
<%=e.getMessage()%>

<%
}
%>

and then the servername is displayed;



Server Name is: <%=server.getName()%>

I use this in a menu and it's handy for diagnostics.

Hi!
I was trying that JMX for a week now and I couldn't get it right.
I was trying to build it on example from eDocs on JMX documentation.
What I missed was the MBean type in line:
java.util.Set mbeanSet = mbeanHome.getMBeansByType("ServerRuntime");

In mine I was just passing "Server"... and it gave me a list of all the servers.

Thanks a million for your help!

Regards,

Suzann

You're welcome - glad to finally help someone!

Pete

These are certainly both viable options but I'm curious, it looks like
Suzann, the OP, just wanted to see which server handled the request for the
JSP page. If all you want is the name of the server that handled the
request and no other runtime information why not make it exponentially more
simple and just use something like <%= System.getProperty( "weblogic.Name" )
%>

I am going to use this option instead for now.
However in future versions, I think I'll need to go back to JMX anyway

Thanks

BTW: what is "OP"
> ... Suzann, the OP, ....

Excellent, didn't know that option existed. I'd just seen the JMS
working on the snoopservlet so borrowed the code.

Learn something new every day!

OP is an old usenet idiom for ``original poster'' ;-)

That might not give the result you think it will. What you've provided
below gives the hostname of the machine the managed server is deployed on
which is not guaranteed to be the name of the managed server per se, nor
should it be IMO
