Hi Vaijayanthi Mala Suresh,

Here is my little example:
http://ivanceras.blogspot.com/2009/04/gcj-vs-jvm-benchmark.html

    $gcj -c -g -O Test.java
    $gcj --main=Test -o Test.bin Test.o
    $./Test.bin

and here's how you would compile jar library file(ie. postgresql jdbc
driver) and link it to your main class
http://ivanceras.blogspot.com/2009/05/gcc-vs-jvm-benchmark-2.html

  Compiling, Linking and Running in GCJ:

  compile the PostgreSQL jdbc driver
   $gcj -c -g -O postgresql-8.4dev-700.jdbc3.jar
   This will create the native binary file "postgresql-8.4dev-700.jdbc3.o"

  compile the Test
   $gcj -c -g -O TestDb.java
  This will create the native binay file "TestDb.o"

   do the linking
  $gcj --main=TestDb -o TestDb.bin postgresql-8.4dev-700.jdbc3.o TestDb.o
  This will create the executable file: "TestDb.bin"

  execute
  $./TestDb.bin

Please visit the blog for more details :)

Regards,
ivanceras
