java (J2EE 1.4) convert to J#

• arunvenkata

  Hi,
  
  J# doesnt implement J2EE stack in itself. You would have to use JLCA to convert to .NET
  
  For the J2EE versions supported by JLCA please refer to the following link.

  Hi,
  
  In some places I have found something about convert Java Bytecode to .Net bytecode. The .Net bytecode can be converted to one of the languages like C#, J#, VB.NET.
  
  I am speaking truth
  If it's, tell me how to convert java bytecode to .Net bytecode...
  
  Thank's

  Hi,
  
  I have tryed this solution but it gives me about 36000 errors. It doesn't support J2EE 1.4. It supports only J2EE 1.3.
  
  Thank's

  Generally my experience doing this always leads me to running the J2EE code under Object Web or JBoss's free J2EE server and building either a webservice or RMI invocation layer to bridge the .NET code. This does assume that you have a good MVC design where you can easily seperate the backend J2EE components from the  frontend. http://www.jnbridge.com/ is a good choice as well.
  
  Most clients when shown the price of a full .NET conversion vs an integration solution choose the cheaper integration solution. (Although some opt for a non-opensource J2EE server as they desire contracted support.)
  
  I know this doesnt help your specific problem but so far I've had limited success with conversion tools (even with J2EE 1.3 and lower) and usually end up hand coding quite a bit of the work. And to be honest I find coding the integrated solutions a delight.

  Hi,
  So far, wE do not support JDK level higher than 1.1.4 in J#. We know that it doesn't sound good to you but that is the truth :(.
  There is no way to port your JDk1.4 app other than deleting the code specfic to versions greater than JDK 1.1.4.
  
  Thanks.

  Hi,
  
  try to make a new J# project in Vidual Studio and add you existing code files to it. Then compile the project and tell me if it worked I'm very interested about it.

  Hi,
  Here are the details of what is supported by J#/JLCA...
  
  1. J# supports the functionality equivalent to most JDK level 1.1.4 class libraries and equivalent to the level of many of the classes in the JDK 1.2 java.util package specified in College Board's Advanced Placement curriculum for Computer Science.
  
  2. JLCA supports upto JDK level 1.3 only. For the details that what (in java) is mapped to what (in C#) please refer to ...
