This bug has been fixed in Release 2007a (R2007a). For previous product releases, read below for any possible workarounds:
There is an ambiguity in the documentation for MATLAB Builder for Java 1.0 (R2006b) when compiling the java components.
First, the command given in the documentation needs to be executed on a single line, however it is not clear where spaces need to be. Also, the documentation for the magicsquare example assumes that you have copied the file getmagic.java into the directory called magicsquare which was created by the builder
You can view this example by executing the following command at the MATLAB Command prompt.
web([docroot,'/toolbox/javabuilder/ug/bqppjqq-10.html#bqppjqr-13'])
After building the java project with DEPLOYTOOL, do the following to compile getmagic.java:
1. Copy getmagic.java into the project folder magicsquare created by DEPLOYTOOL. This folder should now have the file getmagic.java and two subdirectories, distrib and src.
2. Open a DOS command prompt, and change the directory to the folder magicsquare.
3. Execute the following command all on one line.
javac -classpath .;$MATLABROOT\toolbox\javabuilder\jar\javabuilder.jar;.\distrib\magicsquare.jar getmagic.java
(where $MATLABROOT is the MATLAB root directory on your machine, as returned by typing:
at the MATLAB command prompt.)
Note that there is a space between "-classpath" and ".;$MATLABROOT", but there is no space between "javabuilder.jar;" and ".\distrib".
Also, the command to execute the above example from the same directory as you compiled is:
java -classpath .;D:\Applications\MATLAB\R2006b\toolbox\javabuilder\jar\javabuilder.jar;.\distrib\magicsquare.jar -Djava.library.path=D:\Applications\MATLAB\R2006b\bin\win32;.\distrib getmagic 5
