This problem has troubled me two days!class cant visit class between jars;

Question

I set classpath: CLASSPATH:C:\Documents and Settings\xxxx
in this directory,I have a jdbc.jar and a sub directory named t,Test class in t ;
Test class code here:
package t;
import jdbc.DateParser;
public class Test{
    public static void main(String[] args){
        DateParser parser=new DateParser();
        String s=parser.formatDate("1987/9/9");
       System.out.println(s);
}I do this:
C:\Documents and Settings\xxxx>java t.Test
1987/09/09 00:00:00
this Test class run successfully
and I do this(note: in MANIFEST.MF,just only this words at first line : Main-Class: t.Test) :
C:\Documents and Settings\xxxx>jar cvfm t.jar MANIFEST.MF t
list (manifest)
add：t/(read= 0) (write= 0)(stored 0%)
add：t/Test.java(read= 237) (write= 159)(compressed 32%)
add：t/Test.class(read= 524) (write= 347)(compressed 33%)
C:\Documents and Settings\xxxx>java -jar t.jar
Exception in thread "main" java.lang.NoClassDefFoundError: jdbc/DateParser
at t.Test.main(Test.java:5)
this execution is failed?

Actually, ignore that. I think the problem is you are using "java -jar xxx". This runs the JAR in encapsulated mode, which ignores any classpath setting.you mean using "java -jar xxx" cant let xxx visit a class that in another jar?
if that,what command shoud I use?
