All Implemented Interfaces:

Serializable, javax.servlet.jsp.tagext.BodyTag, javax.servlet.jsp.tagext.IterationTag, javax.servlet.jsp.tagext.Tag, javax.servlet.jsp.tagext.TryCatchFinally

public class ErrorsTag
extends AbstractScriptHandlerTag
implements javax.servlet.jsp.tagext.TryCatchFinally

Custom tag that renders error messages if an appropriate request attribute has been created.

This idea for this class came from a - much more powerful - class done by Craig R. McClanahan for the Apache struts framework.
