Problem with rms

Question

Hello everybody,I am using rms for record managment system.The problem is that whenever I search the recorde it does't give the
correct answer.How we reopen a recordset when it is aleready closed.
please give me some searching code in rms
the code snippet:
byte outputRecord[];
int outputStateID[]={1001,1002,1003,1004,1005};
String outputStateName[]={"Delhi","Punjab","Uttarakhand","U.P","Bihar"};
int outputCityID[]={2001,2002,2003,2004,2005};
recordStoreState=RecordStore.openRecordStore("StateRecordSet", true);
ByteArrayOutputStream outputStream=new ByteArrayOutputStream();
DataOutputStream dataOutputStream=new DataOutputStream(outputStream);
for(int i=0;i<outputStateName.length;i++){
dataOutputStream.writeInt(outputStateID);
dataOutputStream.writeUTF(outputStateName[i]);
dataOutputStream.writeInt(outputCityID[i]);
dataOutputStream.flush();
outputRecord=outputStream.toByteArray();
recordStoreState.addRecord(outputRecord,0,outputRecord.length);
//outputStream.reset();
outputStream.close();
dataOutputStream.close();
catch(Exception error){
System.out.println("Error occured:"+error);
try{
byte[] byteInputData=new byte[200];
ByteArrayInputStream inputStream=new ByteArrayInputStream(byteInputData);
DataInputStream inputDataStream=new DataInputStream(inputStream);
recordEnum=recordStoreState.enumerateRecords(null,null,false);
//System.out.println("Success record");
while(recordEnum.hasNextElement()){
recordStoreState.getRecord(recordEnum.nextRecordId(), byteInputData, 0);
inputDataStream.readInt();
state.append(inputDataStream.readUTF(),null);
inputDataStream.readInt();
inputStream.close();
catch(Exception error){
System.out.println("Error in reading: "+error);
and the searching code is like :
public void searchCityID(String sName){
try{
byte inputData[]=new byte[100];
ByteArrayInputStream inputStream=new ByteArrayInputStream(inputData);
DataInputStream dataStream=new DataInputStream(inputStream);
recordStoreState=RecordStore.openRecordStore("StateRecordSet",false);
if(recordStoreState.getNumRecords()>0){
filter=new Filter(sName);
recordEnum=recordStoreState.enumerateRecords(filter,null,false);
while(recordEnum.hasNextElement()){
//System.out.println("Testing the programe");
recordStoreState.getRecord(recordEnum.nextRecordId(),inputData,0);
int citycode=dataStream.readInt();
System.out.println("CityName"+dataStream.readUTF());
dataStream.readInt();
System.out.println("CityCode:"+citycode);
inputStream.close();
catch(Exception error){
System.out.println("RecordSet not Exists"+error);
please help me ,its urgent

Hi prayagrawat,
I tried your code. Actually you should have put the whole java code here. Because you have a class called Filter. and u havent put that in here. So I change your code to enumerate records without the filter. And it is working fine.
Here is the output i got,
CityNameDelhi
CityCode:1001
CityNamePunjab
CityCode:1002
CityNameUttarakhand
CityCode:1003
CityNameU.P
CityCode:1004
CityNameBihar
CityCode:1005
I think there is something wrong with your Filter class.
And another thing you dont have to open da record store again to get the state id and city id. What you can do is just store those values in int []s when you r reading the city names :D. If you are putting city names to a list and when you need to get the city code. what you have to do is just get the selected index from the list and get the city code from int [] using selected index. And remember one thing. if you are sorting the names of citys just change the int []s accordingly.
I think this will help you a little.
