I coded a simple class: test and compiled it and put it in the 'D:\Dropbox\projects\ICPR2013\code\java\union_find'.
public class test {
public test() {
System.out.printf("hello world!");
}
}
And then I use the following code to bring the defined class to the Java class path. I also use javaclasspath to make sure that the folder including 'test' class is added to the Java class path.
javaaddpath('D:\Dropbox\projects\ICPR2013\code\java\union_find');
But when I use x = javaObjectEDT('test'); to call the 'test' class, it gives me the following error: No class test can be located on Java class path

zhang - have you verified that the test.class file is in the D:\Dropbox\projects\ICPR2013\code\java\union_find folder? I used your code for the test class and was able to create an instance of it. I added the folder to the java path using a similar call to javaaddpath and then just observed
>> x = javaObjectEDT('test');
hello world!>> x
x =
test@13265564
