Compiling jar file using gcj

[Swapnil Jain]

Hi,

i created a java project using netbeans. it uses 2 libraries  
RXTXcomm.jar & mysql-connector-java.jar

after building the project thru netbeans i get the iRemote.jar file in  
the dist folder.

i want to compile it using gcj to create a binary file. i am using the  
following command

gcj --classpath=lib/RXTXcomm.jar --main=iremote.controller.Controller - 
o iRemote.bin iRemote.jar


i get the following error
