NoClassDefFound错误-Spring JDBC

Question

Right now, I'm compiling my .class files in eclipse and moving them over to my %tomcat_home%\\webapps\\myapp\\WEB-INF\\classes directory. They compile just fine.

I also have in the ...\\classes directory a org.springframework.jdbc-3.0.2.RELEASE.jar which I have verified has the org.springframework.jdbc.datasource.DriverManagerDataSource class inside it.

However, I get a NoClassDefFound error when I run my class and it tries to DriverManagerDataSource source = new DriverManagerDataSource();

I don't understand why it wouldn't be finding that jar.

Any help is appreciated!

Answer 1

webapp中的jar文件应放在WEB-INF/lib ，而不是WEB-INF/classes 。
