Hello,
I am having a problem trying to call MBean from a jsp file.
I am using tomcat5.5.9. The jsp worked once!!!! so I don't think anything is missing (like import, etc) but for some reason it does not work now.
I do hope you can help me.... I am completely desperate!
THanks
I am using an rmi example that comes in the directory: jmxremote-1_0_1-bin/exampl
es/Basic/r
mi.
Under this directory, the file Client.server is the one I want to modify in order to use a index.jsp file.
The index.jsp file connects to the Server without problem. (see log output)... but when I am trying to get an attribute I get a strange exception:
org.apache.jasper.JasperEx
ception: Unable to compile class for JSP
Generated servlet error:
Only a type can be imported. java.io resolves to a package
Log output:
=======
Create an RMI connector client and connect it to the RMI connector server
Get an MBeanServerConnection
=======
the jsp file is as follows:
==============
