packages

hey there, i dont do much java and you will be able to see why now

say if have a package com.me

i have two classes in this package myUtils and myFun

they have a number of methods and these work fine if i call them from a jsp individually, however when i want to call a method from myUtils whithin myFun and compile, i get an unresolved symbol.

eg:
package com.my
public class myUtils {

public void myUtils() {}
public void aMethod(){}
}

package com.my
public class myFun {

myUtils blah = new myUtils();
blah.aMethod();
}

have i compiled them correctly or is there something else i am not doing properly?

thanks for any help!

1) Sounds like a CLASSPATH issue. Make sure that the com.my package is on your SYSTEM CLASSPATH. So if the com directory is located in a classes directory you need to put that classes directory on the CLASSPATH.

2) One minor note on myUtils.

Incorrect:
package com.my
public class myUtils {

/* Not a Constructor because of void */
public void myUtils() {}

public void aMethod(){}
}

Correct:
package com.my
public class myUtils {

public myUtils() {}
public void aMethod(){}
}

3) Major problem in myFun.
Incorrect:
package com.my
public class myFun {
/* These need to be in a method */
myUtils blah = new myUtils();
blah.aMethod();
}

Correct:
package com.my
public class myFun {

public static void main(String args[]) {
myUtils blah = new myUtils();
blah.aMethod();
}

}

Thanks mate!

yeah, i just wrote those quickly as an example, sorry, very sloppy.

you were right though, was a problem with my compilation method, i found that it sorted itself out when i compiled all the class files together...maybe that is what i was meant to be doing from the start, and would have saved me a couple of hours of frustration =) and the circus leaves town...
