Eclipse에서 tomcat7 서버를 설정하고 내 JSP 파일을 읽었습니다. 로그인 페이지가 나타나기 때문에 SQL 데이터베이스에 연결할 수 없습니다.
은 여기 내 구조
1. tmp0
2. conf
* context.xml
* server.xml
* tomcat-users
* web
3. lib (im not sure i need this in here as i believe it pulls the lib folder from C:/apache/tomcat7/lib. The lib contains the "mysql-connector-java-5.1.40-bin")
4. logs
5. temp
6. webapps
* ROOT
- WEB-INF
