Caroline, Are you having problems with the username or the keyName hidden variable? If it is the username, then I'd suspect that request.getRemoteUser() in your JSP is returning null.

Unable to Pass A Hidden Field To scaffold.ProcessAction 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 --- Caroline Jen <[EMAIL PROTECTED]> wrote: > I want to pass two hidden fields; username and > keyName > 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> > > How come the username is not passed to the FindEditorData.java while > the keyName is successfully > passed.
