Display records in JSP

Question

I am completely stuck at this point and need urgent help.
here is what i have done till now:
i have one jsp page called first.jsp which displays records in RowsetBrowser from View Object A.
The attributes are ID,name,Location.
in View Object A i have added a transient attribute to which i have given an expression
as: ''| |ID| |'', i want to make the id as a link to the edit page,
i do not want an additional column to show up as link,hence i am not using addTextUrlColumn method.
now on clicking on this id,edit.jsp page is called and the parameter p which is the id is passed to
edit.jsp page.
The edit.jsp page is based on another View Object B.
the code is as follows:
String param=request.getParameter("p");
oracle.jbo.html.databeans.RowsetNavigator rsn;
rsn=(oracle.jbo.html.databeans.RowsetNavigator) new oracle.jbo.html.databeans.RowsetNavigator();
rsn.initialize(application,session,request,response,out,"NTS_NTS_NTSModule.LogPanelView");
rsn.getRowSet().getViewObject().setWhereClause("ncc_log_id="+param);
rsn.getRowSet().getViewObject().executeQuery();
The results of above query is only one record,which is right.
my job is now to display all the attributes of the above record,in text fields or
combo boxes.

Hi Monali,
If I understand your attribute Number1 (and Number 2) is one string value (varchar2 type, long type etc. in Entity) which include in self more different values (other strings or numbers). Right? You can do this if you parse string with an method which analyse that string and give you all the values in an array. Then you can display all the values just like you display other attributes. Off course between the values within attributes value must exist an sign (;, |, ^ etc.) which separate one value from another.
Format is:
SignValue(1)SignValue(2)SignValue(3)SignSignValue(maxData)Sign
(e. g.)
Format 1:
|Ad45gt63e4|34f5t55B4|3d563H6a2|5G67sE3h7||d45fgh5|
First sign (|) in the string is separator between the values
Format 2:
;Friday;September 07;2001;Baker Street 21b;LONDON;Europe;;JSP;12345678;EJB;
First sign (;) in the string is separator between the values
I write one demo application (Parse) which you can see in listing 1: Parse.java (see below). Maybe isnt the best solution for this problem but working :-)(compile and run from java console)
In your case code maybe look like in listing 2: BrowserBean.java (see below)
I hope this help you...
Veso
Note: Sample code in listing 2 I write from my head (without testing), so maybe has errors.
Parse.java
public class Parse {
public static String CheckValue(String strValue){
int strEnd;
char strSign = strValue.charAt(0);
strEnd = strValue.indexOf(strSign,1);
strValue = strValue.substring(1, strEnd);
return strValue;
public static void main(String[] args) {
final int maxData = 100;
int sAllValues;
String sEmpty = "";
String[] sAllValuesNumber1 = new String[maxData];
String sValueNumber1 = ";Friday;September 07;2001;Baker Street 21b;LONDON;Europe;";
try {
sAllValues = 0;
while (sValueNumber1 != null && !sValueNumber1.equalsIgnoreCase(sEmpty) && !sValueNumber1.equalsIgnoreCase(sValueNumber1.substring(0,1))) {
sAllValues++;
sAllValuesNumber1[sAllValues-1] = CheckValue(sValueNumber1);
System.out.println(sAllValuesNumber1[sAllValues-1] + "\n");
sValueNumber1 = sValueNumber1.substring(sAllValuesNumber1[sAllValues-1].length() + 1);
} catch(Exception ex) {
throw new RuntimeException(ex.getMessage());
BrowserBean.java
package demobeans;
import java.io.PrintWriter;
import java.io.OutputStream;

public class BrowserBean extends oracle.jdeveloper.html.DataWebBeanImpl {

strEnd = strValue.indexOf(strSign,1);
strValue = strValue.substring(1, strEnd);
return strValue;
public void render() throws Exception {
final int maxData = 100; // number of values for attributes (Number1 or Number2)
int sAllValues1;
int sAllValues2;
String sData = null;
String sEmpty = "";
String sQuery = request.getParameter("id");
String sValueID = null; // if is ID column1 in ViewObject
String sValueName = null; // if is name column2 in ViewObject
String sValueNumber1 = null; // if is name column3 in ViewObject
String sValueNumber2 = null; // if is name column4 in ViewObject
String[] sAllValuesNumber1 = new String[maxValues];
String[] sAllValuesNumber2 = new String[maxValues];
Row[] drows = qView.getAllRowsInRange();
AttributeDef[] dattrs = getDisplayAttributeDefs();
for (int rowno = 0; rowno < drows.length; rowno++) {
for (int j = 0; j < dattrs.length; j++) {
if (!shouldDisplayAttribute(dattrs[j]))
continue;
if (drows[rowno] != null) {
Object attrObj = drows[rowno].getAttribute(dattrs[j].getIndex());

sValue = attrObj.toString();
switch (dattrs[j].getIndex()) {
case 0 : sValueID = sValue; break;

sValueNumber1 = sValueNumber1.substring(sAllValuesNumber1[sAllValues1-1].length() + 1);
sAllValues2 = 0;
while (sValueNumber2 != null && !sValueNumber2.equalsIgnoreCase(sEmpty) && !sValueNumber2.equalsIgnoreCase(sValueNumber2.substring(0,1))) {
