Ant javac: package does not exist

Question

Trying to compile a Web Project here but I keep on getting package does not exist exception for tens of classes. Everything seems to be in classpath and yet it can't find it. Any hint on debugging this issue?

Exception:

 [javac] Compiling 73 source files to C:\workspace\SalesWeb\WebContent\WEB-INF\classes
 [javac] C:\workspace\SalesWeb\src\java\com\abc\xyz\supplier\interceptor\InfoInterceptor.java:8: package org.springframework.web.servlet does not exist
 [javac] import org.springframework.web.servlet.HandlerInterceptor;

Answer 1

Everything seems to be in classpath and yet it can't find it.

The key word there is "seems". The exception tells you that they're not.

I'd create an Ant CLASSPATH that includes what you need and try again.

Answer 2

Is the Spring JAR file in your WEB-INF/lib folder?

Everything should "just work" in this case...

Is it assumed to be packaged with your server?

You may have to add the path to the Spring JAR in your Eclipse project / ANT file.
