I thought that all classes directly under WEB-INF/classes I visible to everybody in current application. The packages and classes in WEB-INF/classes are placed in the classpath. But just like classes in java.util and other packages, you need to import the packages and classes that you will use. So how do I import it Just like any other classes. One caveat: classes imported into JSPs must be in a package other than the default. Otherwise, the container will be unable to find it.

I get the error "List cannot be resolved to a type " When I look at the java class that was generated from the JSP, its missing the import for java.util.List. This seems to be an issue with collections without generics: List alphabetIndexList = new ArrayList(); If I rewrite this to use generics, the error goes away: List alphabetIndexList = new ArrayList(); However, there is also a problem when using List and initializing to a List: List = getList(); (getList() return List) So in this case it seems like the JSP precompiler is not adding the import for List, which may have something to do with the fact that its an interface. There does not seem to be any setting in the element to control this behavior, perhaps its a bug? THis worked with Weblogic and Tomcat.

Does the jsp have at the top? Edit: meant to ask if it had this at the top, but the editor keeps throwing it away: <%@page import="java.util.*"%> JoshuaBurns (1) Mar 31, 2015 at 09:57 AM 0 YEs
