问题 I am using JPA 2.0 ( EclipseLink provider) with Glassfish v3.0.1 and NetBeans 6.9.1 and am NOT able to see the queries and other logging information from JPA 2.0. Essentially I want to be able to see all the SQL statements which are being generated by JPA and other related debugging information... Has anyone successfully been able to configure the logging to provide such feedback? I've tried several things to no avail... Any help would be greatly appreciated. Thanks much. 回答1: What eventually

问题 How can I drive the debugging session with some scripting language like ruby? Is there any easier options than using Expect or some similar module with a scripting language? 回答1: You may be able to use JRuby to drive your own debugger via the JPDA API. 回答2: Check out jdiscript; it's a thin scripting frontend for the JDI that can be used with Java, JRuby, or any other jvm language. 来源： https://stackoverflow.com/questions/630044/how-to-script-the-java-debugger-command-line-tool-jdb

问题 So far, debugging in GWT super dev mode seems to be a real pain. If there are any errors, there is no stack trace, just a cryptic message given in the chrome console. Is there a way to get all errors to print a stack trace, like in the dev mode? I already have source maps on I believe, since if I go to Sources in Chrome's dev tools, I can see the source code of my java classes. 回答1: GWT.setUncaughtExceptionHandler lets you set an exception handler, which will handle all exceptions. You can

问题 I have a crash dump for a customer's application built with a very old version of our dll (release build, don't have original symbols) that I've been analyzing in WinDbg. In order to get more information, I rebuilt the dll in release mode, with symbols this time, using the same compiler version and I believe the same settings as when the dll was originally built. I added the symbol file to my symbol path, but the WinDbg extension !itoldyouso tells me the module in the dump doesn't match the

问题 I have an external DLL whose source code is C#. From the documentation for the DLL, I determined that it writes its debug messages to the console using Console.WriteLine . I'd like to use this DLL within a WinForms application. However, what I have discovered is that I cannot see the debug messages emitted by the DLL since a WinForms application does not have a console. is there a way to capture those debug messages, perhaps even to a simple log file? Of course, using ProcessInfo

问题 GOAL: I'm trying to apply a Like button to my blog - this is my first time trying it. BEHAVIOR: The button shows up, but when someone clicks "Like", the word "error" shows up in red next to the like button. No interaction with Facebook occurs. FIX TRIED: I've tried both the iframe and the html5 implementation, same behavior using both methods. FIX TRIED #2: The word "error" shows up as a hyperlink suggesting I use the Facebook Linter, so I did. However, when I put in my URL, the Linter gives

问题 The code I'm currently working on requires adding an NSNumber object to an array. All of the NSNumbers with value 0-12 are added fine, but 13 onward causes a EXC_BAD_ACCESS.
