using other classes in a project : class cannot be resolved or is not a type [message #64323]

When I try to create an object wich depends on another class, eclipse
can't compile the java file ("[OtherClassName] cannot be resolved or is
not a type"). With the command line (javac) on winXP it works well.

The class I want to use is in the same directory as the .java file and I
don't have the source of that file, only the class (but the class works
fine because javac can compile it using command line).

How can I fix this problem?

thanks

The .class that you depend on must be included on the build path of the
project, not in its source path.

For example, let's say you have a project like this:
MyProject/
source/
com/
foo/
ClassYouWrite.java
lib/

If the .class that you depend on is in package com.x.y, then you would
place that .class in lib/com/x/y directory and include lib/ on the build
path for the Project.

The Help tutorials would explain this in detail - I urge you to go
through them to better understand Eclipse project structures.

source and class files are in the same project directory (small
project). Also the .class I want to use is that project directory.
Shouldn't it be automaticly recognized / in the classpath?
