Javac: invalid flag error while trying to compile using Library Compiler

Hello all,

I'm new to MATLAB and to Java so I'm pretty lost here. I'm trying to convert a MATLAB GUI into a standalone Java application. I used the Library Compiler tool to package the code into a Java package as described here:

http://www.mathworks.com/help/compiler_sdk/gs/create-a-net-application-with-matlab-code.html

But I'm getting lost at the step after running the installer. I created the getmagic.java file in the same directory as the makesqr.jar file and attempted to run the following command:

javac -classpath "mcrroot\toolbox\javabuilder\jar\javabuilder.jar";.\getmagic.java .\makesqr.jar

I get the error

javac: invalid flag: .\makesqr.jar

Are my files not saved in the correct place? Thanks in advance!
