Hello,
I am new to struts and am trying to get a set of multiple fields to work on
both the request and response page. The page needs to be able to display a
set of fields that are determined at runtime (therefore no specific set and
get methods can be used). I've got it working under a non-struts
environment, but can't get it to work under struts.
My main question is how to turn it into struts and still keep the same
functionality. If I just change the form elements to Struts HTML elements,
it doesn't function (with an Action object that simply forwards it onto the
results page).
Here's what I have for the non-struts solution:
Initial Page:
<html>
<head><title>JSP Page</title></head>
<body>
<jsp:useBean id="multitest" scope="request"
class="com.summitsite.trueimage.MultiBean" />
<form action="MultiResults.jsp">
<% String[] fieldNames = multitest.getDocumentFieldNames();
String currentName = null;
for (int i = 0; i < 10; i++) {
currentName = fieldNames[i];
<p><%= currentName %>: <input type="hidden" name="fieldName"
value="<%= currentName %>" />
<input type="text" name="documentSearchField" size="40"
/></p>
<% } %>
<input type="submit" value="Submit"/>
</form>
</body>
</html>
Results Page:
<html>
<head><title>JSP Page</title></head>
<body>
<jsp:useBean id="multitest" scope="request"
class="com.summitsite.trueimage.MultiBean">
</jsp:useBean>
<%
String[] setFields =
request.getParameterValues("documentSearchField");
String[] setNames = request.getParameterValues("fieldName");
if (setFields != null) {
for (int i = 0; i < setNames.length; i++) {
multitest.setDocumentSearchField(i, setFields[i]);
multitest.setFieldName(i, setNames[i]);
}
for (int i = 0; i < setNames.length; i++) {
out.println("<p>" + multitest.getFieldName(i) + ": "
+ multitest.getDocumentSearchField(i) + "</p>");
}
}
%>
</body>
</html>
Bean:
public class MultiBean extends ActionForm implements Serializable {
private String[] documentSearchField = new String[50];
private String[] fieldName = new String[50];
public MultiBean() {
}
public String[] getDocumentSearchField() {
System.out.println("String[] getDocumentSearchField()");
return documentSearchField;
}
public void setDocumentSearchField(String[] fields) {
System.out.println("void setDocumentSearchField(String[]
fields)");
this.documentSearchField = fields;
}
public String getDocumentSearchField(int i) {
System.out.println("String getDocumentSearchField(int i)");
return documentSearchField[i];
}
public void setDocumentSearchField(int i, String field) {
System.out.println("void setDocumentSearchField(int i,
String field)");
this.documentSearchField[i] = field;
}
public String[] getDocumentFieldNames() {
System.out.println("String[] getDocumentFieldNames()");
String[] array = new String[15];
for (int i = 0; i < array.length; i++) {
array[i] = "Field " + i;
}
return array;
}
public String[] getFieldName() {
return fieldName;
}
public void setFieldName(String[] fields) {
this.fieldName = fields;
}
public String getFieldName(int i) {
return fieldName[i];
}
public void setFieldName(int i, String field) {
this.fieldName[i] = field;
}
}
Any assistance would be greatly appreciated. Thanks,
Michael Lundin
