fails to compile an import if it is in the unnamed package
Summary: fails to compile an import if it is in the unnamed
package
Product: Tomcat 4
Version: 4.1.24
Platform: PC
OS/Version: Other
Status: NEW
Severity: Normal
Priority: Other
Component: Jasper 2
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: bert@gildrum.com
Looks like the java compiler included in Tomcat 4.x is failing to compile
an import statement if the class it refers to belongs to the "unnamed package"
see
http://java.sun.com/docs/books/jls/second_edition/html/packages.doc.html#26639
for info on "unnamed package"
- see the various supporting info below.
- note that ACJJspBean is a public class in the "unnamed package"
- also FYI the ACJJspBean.class file is in <context>/WEB-INF/classes
As far as I can tell, this is supposed to be a legal use of an import statement.
And yes, it is from an example piece of code from a 3rd party package
