I did not mess up lowercase and uppercase of the
hidden field I want to pass from my JSP to the
scaffold.ProcessAction. If it had been the
lowercase/uppercase problem, I would have gotten a
message saying that the variable could not be
recognized.
I pass two hidden fields at the same time. One of
them is successfully passed with correct value. The
other is passed but its value shows a 'null' in the
scaffold.ProcessAction. What could go wrong? Let me
show my code again:
Two hidden fields: username and keyName are passed
from a JSP via a SUBMIT button:
<req:isUserInRole role="editor">
<html:form action="/find/Category">
<% String username = request.getRemoteUser();%>
<html:hidden property="keyName"
value="journal_category"/>
<html:hidden property="username"
value="<%=username%>"/>
<html:submit>View Articles</html:submit>
</html:form>
</req:isUserInRole>
and an action mapping:
<action
roles="editor"
path="/find/Category"
type="org.apache.struts.scaffold.ProcessAction"
parameter="org.apache.artimus.article.FindEditorData"
name="articleForm"
scope="request"
validate="false">
<forward
name="success"
path=".article.Result"/>
</action>
The value of the 'username' is found to be a 'null' in
the FindEditorData.java while the value of keyName is
successfully retrieved. In the browser, I got:
name=null; kn=journal_category; kv=null
The code of my FindEditorData is shown below:
public final class FindEditorData extends Bean
{
public Object execute() throws Exception
{
// Obtain username
String username = getUsername();
EditorService service = new EditorService();
String value = service.findEditorData( username );
String property = getKeyName();
if (( null==property ) || ( null==value ))
{
StringBuffer sb = new StringBuffer();
sb.append( "name=" );
sb.append( username );
sb.append( "; kn=" );
sb.append( property );
sb.append( "; kv=" );
sb.append( value );
throw new ParameterException(
sb.toString() );
}
ResultList list = new ResultListBase
(
Access.findByProperty( this,property,value
)
);
list.setLegend( property,value );
return new ProcessResultBase( list );
} // end execute
} // End FindEditorData
