자바 mail을 사용할 때 SE6이상이면 이미 내장되어 있어서 따로 추가할 것이 없지만

class를 못 찾는다고 뜬다면

activation.jar

mail.jar 를 추가해봐라. 

activation.jar

mail.jar

-> 안 됨.

java.lang.class.forname0(native method) java.lang.class.forname(unknown source) 이게 뭔지 궁금해짐.

http://stackoverflow.com/questions/10037499/class-not-found-exception-class-fornamecom-mysql-jdbc-driver-in-webservice

If this code works in your J2SE it means you need to have a JAR file somewhere containing com.mysql.jdbc.Driver class (so called JDBC driver). This JAR needs to be visible in Tomcat. So, I would suggest to place mysql-jdbc.jar at physical location to /WEB-INF/lib directory of your project.

Many times in the past, I have experienced ClassNotFoundException if jar is not at physical location. Then restarting Tomcat should work. 

이렇게 하라고 한다. 

com.mysql.jdbc_5.1.5.jar  내가 받은 파일은 이것 .

톰캣이란 프로젝트 lib에 추가해도 안된다.

파일명을 mysql-jdbc.jar 이렇게 바꿔봤다. 안된다.

javax.servlet.ServletException

에 대해 찾아봤다.

[질문]

Java Build Path/ Libraries에 jeus.jar 파일 경로 잡았습니다.

 

Java Build Path/ Order and Export에 jeus.jar 파일을 최상위로 잡았습니다.

 

jeus.jar 파일을 Build 경로에서 삭제하면 컴파일 에러가 발생합니다.

 

Build Path에 정상적으로 경로를 설정하고, 컴파일도 정상적으로 됩니다.

 

그런데, 실행시키면 아래와 같은 에러가 발생합니다.

 

다른 PC에서 정상적으로 동작하는 WAR파일을 import해서 사용했는데

 

같은 에러가 발생합니다.

 

org.apache.commons.fileupload.DiskFileUpload 를 사용하여 파일 업로드하는 JAVA 파일입니다.

[자답]

NoClassDefFoundError는 말그대로 클래스가 존재하지 않아서 발생하는 에러입니다.

classpath에 해당 클래스가 존재하더라도  상위클래스로더에서 하위클래스로더를 참조하는경우 class의 name space가 달라서 해당 에러가 발생할수 있습니다.

servlet.jar는 JEUS에서 JEUS_HOME/lib/system/jeus.jar와 동일합니다.

혹시 cos.jar 가 servlet.jar 상위클래스로더에 있는건 아닌지 확인할 필요가 있습니다. - >servlet.jar아예없음 파일 받아서 넣어도 안됨.

System ClassPath 또는 JAVA_HOME/jre/lib/ext/ 아래  cos.jar가 있는경우 해당 에러가 발생할수 있습니다. ->없음

servlet.jar

http://www.hadoop-forum.co.kr/_board/content.php?id=50&pass_id=16&secret=0&slug=&page=

ClassNotFoundException의 에러는 대부분 jar 파일의 경로가 틀려서 Class를 찾지 못하는 경우입니다.

검색어 : Servlet.init() for servlet  threw exception

jar파일이 이리저리 옮겨다니면서 상했을 수 있으니 온전한 것으로 바꿔보라고 한다.  뭔가 뭔줄알고..ㅜ

web.xml을 보다가 

log4j.properties 의 경로가 이상하다고 생각되어 졌다. 실제로는 WEB-INF/classes/log4j인데

web.xml에는 WEB-INF/log4j라고 적혀 있었다.

그래서 프로퍼티파일을 web-inf밑에 두고 실행 했지만 같은 에러가 났다.

또 web.xml에서 경로를 클래시스 밑으로 수정했지만 같은 에러가 났다. 

상관없나보다.
