The JAVAADDPATH command can be used to add Java classes to MATLAB's dynamic Java class path irrespective of whether the application is being deployed as a stand-alone application on a target machine or as a MATLAB function on the development machine. However, note that if an absolute path is used to specify the Java class path, make sure that the path exists on the target machine. As an example consider the following function:
function java_test()
javaaddpath('C:\classes')
j=HelloWorld;
end
The above function java_test() uses the Java class 'HelloWorld' which is located in the 'C:\classes' folder specified by the 'javaaddpath('C:\classes')' command. Now, if the above function is compiled and deployed on a target machine, make sure that the Java class file 'HelloWorld.class' has the same path (C:\classes) on the target machine.
Note that it might not be possible for the user on the target machine to have sufficient rights to create folders to match the absolute path of the class files on the development machine and in such cases using a relative path is better suited. The following example demonstrates the how the relative path can be used with the JAVAADDPATH command:
function java_test()
javaaddpath('.\')
j=HelloWorld;
end
In this case, instead of specifying an absolute path for the Java class file, it is specified as relative to the current directory using the 'javaaddpath('.\')' command. Note that this requires the Java class file to be present in the current working directory for both the development as well as the target machines. In this case, make sure that you include the class files along with the .EXE and the .CTF files in your distribution and advise the user of the stand-alone application to place the class files in the same directory as the .EXE and the .CTF files.
