eclipse - How do I debug JSPs on remote JBoss server? -

-

I am debugging an application on a remote server that uses Eclipse using the Zebes my special problem A NullPointerException In a JSP there is a lot more java code inside the script script, but unfortunately, refactoring is not going to be an option. Finding the throwing line <0> NullPointerException has been incredibly challenging and I'm stuck.

How can I debug this JSP remotely? > NullPointerException ?

Until I wasolate this issue, I had to end the problem by commenting on JSP lines. You can enable remote debugging on some application servers by adding something like this 

  -Xdebug -Xrunjdwp: transport = dt_socket, address = 5001, server = y, suspended = n

On the command line. Then, in your IDE, connect to port 5001 for remote debugging. There are some examples for different application servers.

I think debugging JSP can be done easily if you have Javascript compiled JSPs for JSP compile, check your application server's manual or compile your JSP and Save .java files; So use these files as the source of the debugger.

Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

Visual Studio 2005: How to speed up builds when a VSMDI is open? -

Using Visual Studio 2005, if I open the test in VSMFI and try to run the tests, then sometimes the projects are ready. However, they run very slow. CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space. I name the image, then select that image to install Ubuntu in the Verbill box. The virtualbox will never...
