To enable hot code replacement during remote debugging e.g. from the Eclipse IDE you need to add the following java option to the startup script of the Catalina server.
-Xdebug -agentlib:jdwp=transport=dt_socket,address=localhost:8000,server=y,suspend=n In a WebManager Community Edition installation of for example WebManager 9.7.1 this would be the
<<WebManager Installation Folder>>\apache-tomcat\bin\startup.bat
Replace the following line:
set JAVA_OPTS=%JAVA_OPTS% -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n
with
set JAVA_OPTS=%JAVA_OPTS% -Xdebug -agentlib:jdwp=transport=dt_socket,address=localhost:8000,server=y,suspend=n
Restart Tomcat to activate these settings.
