JSP code for Struts or JSTL tag

HI,

I am doing folling stuff in jsp code which I need to do using Struts or using JSTL tag, can any body have a related idea please share.

Below is the JSP code

<%

                        Object category = request.getAttribute("categoryDetails");
                        Hashtable<String, Hashtable<String, Integer>> cat = (Hashtable<String, Hashtable<String, Integer>>) category;
                        //out.print(cat.entrySet());

                        Set<String> functions = cat.keySet();

                        for(String fun : functions){

                            out.print("-----------");
                            out.print(fun);
                            out.print("-----------");

                            Hashtable<String, Integer> obj = cat.get(fun);

                            Vector<String> subFunction = new Vector<String>(obj.keySet());

                            Collections.sort(subFunction);

                            for(String str : subFunction){                            
                                out.print("#"+str+"-"+obj.get(str));
                                }
                        }



                        %>

      

Thanks in advance.

You can use your own tag or create a temporary view structure like:

public class FunctionView {
    String functionName;
    List<SubFunctionView> subfunctions;

    public FunctionView(String functionName, List<SubFunctionView> subfunctions) {
        this.functionName = functionName;
        this.subfunctions = subfunctions;
    }

    public String getFunctionName() {
        return functionName;
    }

    public void setFunctionName(String functionName) {
        this.functionName = functionName;
    }

    public List<SubFunctionView> getSubfunctions() {
        return subfunctions;
    }

    public void setSubfunctions(List<SubFunctionView> subfunctions) {
        this.subfunctions = subfunctions;
    }
}

public class SubFunctionView {
    String subFunctionName;
    Integer value;

    public SubFunctionView(String subFunctionName, Integer value) {
        this.subFunctionName = subFunctionName;
        this.value = value;
    }


    public String getSubFunctionName() {
        return subFunctionName;
    }

    public void setSubFunctionName(String subFunctionName) {
        this.subFunctionName = subFunctionName;
    }

    public Integer getValue() {
        return value;
    }

    public void setValue(Integer value) {
        this.value = value;
    }
}

      



Then you just loop through a method named List getFunctionsView () on your controller and use a simple nested jstl foreach loop.

Edit: We'll have to redo this part a bit.

I wouldn't use it either, looking at the logic involved, I'd rather write my own jsp tag to achieve this. JSTL / Struts are equally good / terrible at doing this.
