[급]리눅스에서 자바 실행에러....!!!

리눅스에서 jdk1.3.1_01을 설치한 후.....잘 돌아갔습니다..
다른건 더 추가한 것도 없는데,,,,
왜 에러가 나는지..모르겠습니다..
며칠전에
java Server하니까....잘만 되던 것이...

path도 다음과 같이 잡아줘서
PATH="$PATH/usr/local/jdk1.3.1_01/bin"
export JAVA_HOME="usr/local/jdk1.3.1_01"
export ClASSPATH="."
......실행도 되고 컴파일도 잘 되었습니다....그런데...
오늘하니까...
다음과 같은 에러메세지가 뜹니다....뭐가 잘못된건지...ㅜㅜ;;;

classpath로 바꿔보고 다 했지만...에러의 내용을 정확하게 모르는지
라....
부탁드립니다...
