Hidden variable

[michell o'brien]

Hi

I am using struts. I want to pass a hidden variable to my action class.

   

<logic:notEmpty name="menArrayList">
<logic:iterate  name = "menArrayList" id="menlist">
<li>
<html:link action = "/mencategory" paramId = "category" paramName = "category_name"><bean:write name="menlist"  property="category_name"/> </html:link>
</li>
</logic:iterate>
</logic:notEmpty>

But when I run my menu.jsp i get this error saying category_name canno tbe found in any scope.

org.apache.jasper.JasperException: javax.servlet.ServletException: javax.servlet.jsp.JspException: Cannot find bean: "category_name" in any scope
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:522)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:398)

Can anybody say me what mistake I am doing

Does the "menlist" bean have a "category_name" property?

Hello Mr.Newton Nice to hear from you back.

Yes, menlist does have category. Let me be more clear by pasting my code

Menform.java

  
private String category_name;
	
	public String getCategory_name() {
		return category_name;
	}
	public void setCategory_name(String category_name) {
		this.category_name = category_name;
	}
  

And my Mencategoryaction.java should get that hidden parameter.

  String category = mencategorylist.getCategory_name();
				System.out.println("Category passed from jsp is " + category);
				try{
				stmt = 	con.createStatement();
				String query = "select category_name from category_info where category_parent_level = (select category_no from category_info where category_name   = ' " +category + "')";
				rs = stmt.executeQuery(query);	
				
				if(category.contains("Apparel")){
					while(rs.next()){
						mencategorylist = new Menform();
						mencategorylist.setApparel(rs.getString(1));
						mencategoryArraylist.add( mencategorylist);
						}
				}
				else{
					while(rs.next()){
						mencategorylist = new Menform();
						mencategorylist.setShoe_Accessiores(rs.getString(1));
						mencategoryArraylist.add( mencategorylist);
						}
			}
			session.setAttribute("mencategoryArraylist", mencategoryArraylist);
			}

AtLast got it.
I had interchanged the paramId and paramName.

   
<logic:notEmpty name="menArrayList">
<logic:iterate  name = "menArrayList" id="menlist">
<li>
<html:link action = "/mencategory" paramId = "category_name" paramName = "menlist" paramProperty = "category_name" scope = "request"> <bean:write name="menlist"  property="category_name"/> </html:link>
</li>
</logic:iterate>
</logic:notEmpty>
