I removed the flush="true" part of the jsp include tag. This time I received this error on a 500 page:
JSPG0080E: Invalid jsp:include tag: org.apache.jasper.JasperException: JSPG00
80E: Invalid jsp:include tag
The code is:
<td><jsp:include page="servlet/com.mycompany.myproject.MyServlet" /></td>
Core Servlets and JavaServer Pages by Marty Hall says:
The jsp:include element has two required attributes, as shown in the sample below: page (a relative URL referencing the file to be included) and flush (which must have the value of true).
<jsp:include page="Relative URL" flush="true" />
Any other ideas?
