problem with bean tag: RequestUtils.lookup exception

[Christophe Andreoli <an...@gsf.de>]

Hi !


I am getting the following exception :


javax.servlet.jsp.JspException
        at
org.apache.struts.util.RequestUtils.lookup(RequestUtils.java:493)
        at
org.apache.struts.taglib.bean.WriteTag.doStartTag(WriteTag.java:179)
        at
org.apache.jsp.proteinList$jsp._jspService(proteinList$jsp.java:290)
        at
org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:107)







My jsp file is the following. I want to iterate over a colletion named
proteinsCollection
in my beanform.

<l:iterate id="prot" name="startForm" property="proteinsCollection">
<tr>

<td align="left" valign="top">

<bean:write name="prot" property="orf"/>
</td>
<td>  
</td>
</tr>
</l:iterate>



The bean form start form looks like:
............
private	Map	proteins		= new HashMap();	

	public Map getProteins() {
		return proteins;
	}
	
	public void setProteins(Map proteins) {
		this.proteins	= proteins;
		
	}
	
	public Collection getProteinsCollection() {
		return proteins.values();
	}
..................

The proteincollection contains proteins objects with a Orf property and
the associated get Methode.


I filled in my action class the startform with proteinscollections.



AND why it doesn't work ????


A idea ?




   Thanks christoph
