Question

My directory structure is:

• ABC/src/com/example/model/a.java
• ABC/src/com/example/web/b.java

Code for a.java:

package com.example.model;

public class a {
    // ...
}

Code for b.java:

package com.example.web;

import com.example.model.*;

public class b {
    // ...
}

I have already set the CLASSPATH environment variable to Tomcat’s servlet-api.jar, so I don’t need to include it in the javac command.

Now a.java compiles fine but when I compile b.java it says “package com.example.model does not exist”.

How is this caused and how can I solve it? I am using Ubuntu 10.10.

Answer 1

Add the output directory (ABC/classes or similar) to the javac classpath so that javac can find the classes.

Edit:

Actually, the preferred way is to add the -sourcepath option, as pointed out by AlexR.

That way, the compiler will use the current source of your code instead of the class files from the last time you compiled.
