Invalid encoding name

[substring]

Hello All,

I have successfully compiled my HelloWorld EJB program with JBoss3.2.1_Tomcat4.1.24 bundle. However, when I run it on my browser, the call method does not work, but there is no error message on the browser. I looked at the messages displayed in my JBoss console, I saw the followings:

//scripts begin----------------------------------

//scripts end----------------------------------

What does it mean?

Thank you very much.

The version of xerces included in 3.2.1
doesn't like
<?xml version="1.0" encoding="Cp1252"?>

Change it to UTF-8

Thanks for the reply.

But I am pretty new to this and I don't understand. What is xerces? Is it a file in the JBoss installation? I did a search for xerces and came up with nothing.

Please explain. Thank you very much.

Xerces is the XML parser that pulls apart the XML files in deployment descriptors read by JBoss. The parser comes from the Apache XML project at http://xml.apache.org. Anyway, Xerces doesn't like your XML because of the character encoding you've chosen. I think the Xerces file is called XercesImpl.jar or something like that.

I gone thru all the xml files in my project folder, and I found a ejb-jar.xml in the META-INF folder that has the encoding entry. As suggested by previous poster, I changed it to:
<?xml version="1.0" encoding="UTF-8"?>

I restarted JBoss and run "ant all" again. Now I got different error messages:
//messages start------------------------------------

//messages end------------------------------------

What does that mean? The 2nd error message even point out the line of code where the error is, but where can I find that line of code? It seems most of these definition files are zipped up as jar files.

Also, how can I check the status of the beans from the JBoss JMX Agent View?

Any help will be very much appreciated.
