• Passing DataSource object from a servlet to a JavaBean

  - by Slavko

  I like the ease of using @Resource annotation to get a DataSource, but as far as I know, it's not possible to use it in a regular JavaBean.

• Get ahold of session in command object in Grails

  - by UltraVi01

  How can I get the session from within a command object? I have tried: import org.springframework.security.context.SecurityContextHolder as SCH class MyCommand { def session = RCH.currentRequestAttributes().getSession() } This throws java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

Possibly by identifying the property names of each class and copying the value over?

• Why Isn't My .Net Object Serializable?

  - by Rob P.

  I've got a 'MyDataTable' class that inherits from System.Data.DataTable I've implemented ISerializable in my class and have a 'Public Overrides Sub GetObjectData...' But when I try to serialize the an object of 'MyDataTable' I get an error saying that 'MyDataTable' is not marked as serializable. If I used a DataTable instead - my code serializes correctly. If I add a serializable attribute to the 'MyDataTable' class - it serializes correctly, but I'm told that is unnecessary if I implement ISerializable. Can someone point me in the right direction?

• Print layout of C++ object with g++ compiler

  - by zaheer

  Is there a way to print the layout of a C++ object using the g++ compiler or any other means. A simplified example (assuming int takes 4 bytes) class A{ int a; }; class B:public A{ int b; } so the output would be A - 0 4 + a + B- 0 4 8 + A.a + b + It would be useful to understand the layout of objects (in my case virtual machine code). Thanks in advance. Regards, Zaheer
