Does anyone know how to get Hot deployment to work with Tomcat?
I am using Struts2, Spring, Hibernate, and MySQL
Tomcat Version: 6.0.16
Java version: JDK 1.6.0_06
Eclipse version: 3.4.0
Tomcat Sysdeo Plugin version: 3.2.1
Struts version: 2.0.11.1
Spring Framework version: 2.5.1
Hibernate version: 3.2.6.ga
MySQL JDBC driver: 5.1.5
C3P0 connection pool: 0.9.1.2
I started tomcat outside eclipse using a remote JPDA debugging connection
(catalina jpda start). And I started tomcat from within Eclipse using the
SYSDEO tomcat pluggin. In both instances, I get the following message right
after I change a line of code and save it when debug stepping. I have also
tried to use JDK 1.5 and had the same error.
"Obsolete Methods on the Stack"
Reason:
The virtual machine was unable to remove all the stack frames running old
code from the call stack.
The virtual machine is not supplying the debugger with valid data for those
frames...
I see the following exception on the logs when the above error is displayed:
