Can in any application usage of JNI with RMI substitute CORBA, if the JAVA application communicates with a C/C++ code. If so then what is the exact role of CORBA in this regard? Please suggest. Thanks in advance.

Hi there, First of all,RMI and CORBA are used for distributed computing/remote process calls. RMI is a pure java (ALL OBJECTS are created in JAVA) implementation of applications involving Remote Process Calls. While CORBA does the same thing, but it will enable your Java application to communicate to objects created in any (java or none java- "any" means as long as it is supported by CORBA) other programming languages. Yes, you're right if you have codes in C and you want it to communicate with java, an alternative to using CORBA is via JNI- you need to create java wrappers for your C codes. And if you want to have RPC implementation you combine JNI with RMI. CORBA does all these for you automatically. I hope this helps. Jonathan

an additional note: CORBA supports many PL's, among all the most popular are C/C++,COBOL, etc. I guess, it really pays off to use CORBA if you have legacy applications coded in COBOL. JNI cannot help you in this case (COBOL). Jonathan

JNI is not really object oriented. So CORBA is a better option for OO C++ code.
