I have one jsp that <jsp:include>'s another and augments the
request parameters using <jsp:param>. The included jsp uses a
taglib tag with the <rtexprvalue> attribute set to true.
The problem is I keep getting the following exception when I use
an expression in the attribute field:
org.apache.jasper.compiler.ParseException:
/WEB-INF/jsp/od.jsp(12,53) Attribute from has no value
Here is the taglib.tld excerpt:
<!DOCTYPE taglib
PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd";>
<tag>
<name>orderDetail</name>
<tagclass>taglib.orddet.OrderDetailsTag</tagclass>
<bodycontent>JSP</bodycontent>
<info></info>
<attribute>
<name>from</name>
<required>true</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
</tag>
The outer jsp file is simple:
<html><head><title>Test</title></head>
<body><center><h1>Test</h1></center>
<jsp:include page="/WEB-INF/jsp/od.jsp">
<jsp:param name="from" value="p:D"/>
</jsp:include>
</body></html>
And the included jsp file isn't much more complicated:
<%@ taglib uri="/WEB-INF/tlds/taglib.tld" prefix="opf" %>
<hr /> <pre>od.jsp<br />
<%= request.getParameter("from") %></pre> <hr />
<opf:orderDetail from="<%= request.getParameter("from") %>">
PO Number:<opf:orderAttr attribute="ponumber"/>
</opf:orderDetail>
If I use the included file as shown then I get the
'Attribute from has no value' Parse exception. If I replace the
<opf:orderDetail> line to a static string <opf:orderDetail from="p:D">
then the file gets included just fine __and__ the getParameter() call
at the top shows that the parameter is, in fact, set.
I really don't understand what I'm doing wrong and would appreciate
any help. This is Tomcat 4.0b7 on Linux RedHat 7.1.
