<c:url param passes null always

[Abdul Wahab]

Hi all,
I am finding difficult to pass parameter value from one jsp to another in my struts application. Below are my code

                                    // My First Jsp page
                                     Contract  No<h:text property="contractno" styleId="contractno" /><br />
 
                                       <c:url var="insertarticle" value="/Prf/insertprfArticle.do">
  						<c:param name="contractno" value="${param.contractno}"></c:param> 
						<c:param name="action" value="insertArticle"></c:param>
					</c:url>
  					<ahref="${insertarticle}">Insert</a></td>   

Whenever i click the link . It Shows contactno always null

http://localhost:8080/Elclass/Prf/insertprfArticle.do?contractno=&action=insertArticle.

Can you please point out where i am wrong?

DO you mean null, or empty? They're not the same thing.

In your URL, the value of the parameter is empty.

Hi bear,
Sorry. It shows empty. Contract No value is set using Agent dropdown list. Below are the code for reference

<fieldset>
        							<legend>Contract Details</legend>
                  				 		Agent:<h:select property="agentname" styleId="agentname" onchange="loadagentvalue();">
          									  	<h:option value="0">select Agent</h:option>         	
          	 										<c:forEach items="${agentarray}" var="agentlist">
          												<h:option value="${agentlist.agentname}">
          													<c:out value="${agentlist.agentname}"></c:out>
          												</h:option>
          											</c:forEach> 
          										</h:select><br />
        								Contract  No.<h:text property="contractno" styleId="contractno" /><br />
        </fieldset>

//javascript code
//Agent DDL	
function loadagentvalue(){		
			var agentname = document.getElementById("agentname").value;
	 		<c:forEach items="${agentarray}" var="agentList">
				var agentvalue  = "<c:out value="${agentList.agentname}"></c:out>";			
			  		if(agentname == agentvalue){
			  			 var myagentvalue = "<c:out value="${agentList.contractno}"></c:out>" ;
			  				 if(myagentvalue.length == 0 )
							{
			  					myagentvalue = "L0001";
							}
			   				document.getElementById("contractno").value = myagentvalue;
					}
				</c:forEach> 
		}

hi,
I tried passing other values still it shows empty. Only constant values (hard coded vales) are accepting.
Guess there might be some issues with my form bean or struts config file. i have attache by form bean and

   public class PrfForm extends ActionForm {
	
	private String contractno;
         
     /**
	 * @return the contractno
	 */
	public String getContractno() {
		return contractno;
	}
	/**
	 * @param contractno the contractno to set
	 */
	public void setContractno(String contractno) {
		this.contractno = contractno;
	}

struts config file

                <form-beans>	  	
		  	<form-bean name="PrfForm" type="sb.elpro.actionform.PrfForm"></form-bean>
		  </form-beans>
                 <action-mappings>
                           <action path="/saveprf" type="sb.elpro.action.PrfAction" name="PrfForm" parameter="action" input="/Jsp/Prf.jsp" scope="session">   
		    		<forward name="gotobtr" path="/Jsp/Debit.jsp"></forward>
		    		<forward name="error" path="/Jsp/Srf.jsp"></forward>	    		
		    	  </action>
 
                          <action path="/Prf/insertprfArticle" type="sb.elpro.action.PrfAction" name="PrfForm" parameter="action" input="/Jsp/PrfArticle.jsp"     scope="session">    			    				    				    			    		
		    		<forward name="getarticle" path="/Jsp/PrfArticle.jsp"></forward>
		    		<forward name="saveprfarticle" path="/Jsp/Prf.jsp"></forward>
		    		<forward name="editprfarticle" path="/Jsp/PrfArticle.jsp"></forward>
		    		<forward name="deletedarticle" path="/Jsp/Prf.jsp"></forward>	
		    		<forward name="cleararticle" path="/Jsp/Prf.jsp"></forward>		    			    		
		    	</action>
             </action-mappings>

Here /saveprf action to save Prf.jsp. /Prf/insertprfArticle action to call PrfArticle.jsp . To call this page i am using <c:url>

hi,
Still confused why the value shows empty . any help on this will be great

[Abdul Wahab]

hi all,
Still unable to find the solution. i created a seperate action (i am using Dispatch action here), to load the form and when i
reloaded the form the url parameter values are passed from one page to another. seems strange
