XSP Compiler Issue: Class Not found

Greetings. I decided that I wanted to try writing an XSP page. I know about logicsheets but just to start I figured Id go the brute force approach. The following is the XSP page.

<?xml version="1.0" encoding="UTF-8"?>
<xsp:page language="java" xmlns:xsp="http://apache.org/xsp"
 xmlns:jconfer="http://www.jconfer.org/">
<xsp:structure>
 <xsp:include>javax.naming.InitialContext</xsp:include>
 <xsp:include>javax.naming.NamingException</xsp:include>
 <xsp:include>javax.rmi.PortableRemoteObject</xsp:include>
 <xsp:include>java.util.Collection</xsp:include>
 <xsp:include>java.util.Set</xsp:include>
 <xsp:include>java.util.Iterator</xsp:include>
 <xsp:include>java.util.Properties</xsp:include>
 <xsp:include>jconfer.data.Smiley</xsp:include>
 <xsp:include>mirror.datafetch.DataFetch</xsp:include>
 <xsp:include>mirror.datafetch.DataFetchHome</xsp:include>
</xsp:structure>

<jconfer:page>
 <xsp:logic>
 try {
 InitialContext ictxt = new InitialContext();
 <message><xsp:expr>ictxt.getNameInNamespace()</xsp:expr></message>

 DataFetchHome dfHome = (DataFetchHome)PortableRemoteObject.narrow(
 ictxt.lookup("JConfer/DataFetch"), DataFetchHome.class);
 DataFetch dataFetch = dfHome.create();
 Collection smileys = dataFetch.performQuery(Smiley.class, null, null, null,
 null, "code ascending");
 Iterator iter = smileys.iterator();
 Smiley tgtSmiley = null;
 <xsp:element>
 <xsp:param name="name"><xsp:expr>"smiley"</xsp:expr></xsp:param>
 while (iter.hasNext()) {
 tgtSmiley = (Smiley)iter.next();
 <xsp:attribute name="code"><xsp:expr>tgtSmiley.getCode()</xsp:expr></xsp:attribute>
 <xsp:attribute name="code"><xsp:expr>tgtSmiley.getDescription()</xsp:expr></xsp:attribute>
 }
 </xsp:element>
 } catch (Exception ex) {
 <message><xsp:expr>ex.getMessage()</xsp:expr></message>
 }
 </xsp:logic>

</jconfer:page>

</xsp:page>

This page is basically a copy of a generator that DOES work .. SHown below.

public class SmileyAdminView extends GeneratorBase {

/** {@inheritDoc} */
public void generateContent() throws Exception {
    DataFetchHome dfHome = (DataFetchHome)jndiLookup(DataFetchHome.class,
                                                     "JConfer/DataFetch");
    DataFetch dataFetch = dfHome.create();
    // --
    Collection smileys = dataFetch.performQuery(Smiley.class, null, null, null,
                                                null, "code ascending");
    // --
    AttributesImpl attributes = new AttributesImpl();
    Smiley tgtSmiley = null;
    // -- Start the content
    this.contentHandler.startElement("", "smiley-admin-view", "smiley-admin-view", EMPTY_ATTRS);
    // -- Do internal elements.
    Iterator iter = smileys.iterator();
    while (iter.hasNext()) {
      tgtSmiley = (Smiley)iter.next();
      attributes.clear();
      attributes.addAttribute("", "code", "code", "", tgtSmiley.getCode());
      attributes.addAttribute("", "description", "description", "", tgtSmiley.getDescription());
      this.contentHandler.startElement("", "smiley", "smiley", attributes);
      this.contentHandler.endElement("", "smiley", "smiley");
    }
    // -- End the document
    this.contentHandler.endElement("", "smiley-admin-view", "smiley-admin-view");
}
}

The problem is that when I try to run the XSP page, the compiler freaks out and cannot find any of the Mirror or JConfer classes. It gives me a class not found on all of them. However the generator works. These classes are deployed in another package and therefore are available to the classloader of the application server but somehow cocoon isnt seeing them. Is there any way I can tell cocoon that they are there? We know they are available because the generator does in fact work.
