I have a web application. It is currently deployed on a remote server in a Glassfish instance. Is it possible to remotely connect to the server and debug the application (like I would a normal java application) using Netbeans?
If someone has done this and could provide insight or could point me to a guide, that would be great.
I know this functionality exists with Visual Studio and ASP.Net. I was not sure if there is a java equivalent.
Most examples that I have seen online are for applications that are simply running on a remote machine or for debugging a Glassfish application running on the local machine.
Yes, it is possible.
Once you have GlassFish running in debug mode, go to the Debug menu in NetBeans and click on Attach Debugger... , which brings up the Attach dialog. You'll probably go with something like:
Debugger: Java Debugger (JPDA)
Connector: SocketAttach
Transport: dt_socket
Host: hostname_or_ip_address
Port: 9009
Timeout may be left blank. When you click OK on this dialog, you should be able to connect your NetBeans debugger to GlassFish.
Remember:
\n-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9009
Read the JPDA docs for other options you can use.
