How to retrieve both SIM and phone book contact using PIM in J2ME.
I Tried
PIM.getInstance().listPIMLists(PIM.CONTACT_LIST);
but it's only displaying Phone book contact.
May be this method can help you
public static HashLongObject loadContactFromPhone() {
PIM iPim = PIM.getInstance();
String[] allContactLists = iPim.listPIMLists(PIM.CONTACT_LIST);
// Phone or SIM
HashLongObject iPhoneBookList = new HashLongObject();
int i;
for (i = 0; i < allContactLists.length; i++) {
try {
PIMList iPIMList = iPim.openPIMList(PIM.CONTACT_LIST, PIM.READ_ONLY, allContactLists[i]);
Enumeration iPimListEnum = iPIMList.items();
String iContactName, iTelNumber;
String []arrName;
boolean isSupportFormettedName = iPIMList.isSupportedField(Contact.FORMATTED_NAME);
if(isSupportFormettedName) {
while (iPimListEnum.hasMoreElements()) {
try {
Contact iContact = (Contact) iPimListEnum.nextElement();
iContactName = iContact.getString(Contact.FORMATTED_NAME, 0);
iTelNumber = iContact.getString(Contact.TEL, 0);
} catch (Exception e) {
Logger.logStackTrace(e);
continue;
}
long corePhoneNumber = StringUtils.toCCPhoneNumber(iTelNumber);
// Check Duplicate
if (iPhoneBookList.containsKey(corePhoneNumber)) {
continue;
}
iPhoneBookList.put(corePhoneNumber, iContactName);
}
} else {
while (iPimListEnum.hasMoreElements()) {
try {
Contact iContact = (Contact) iPimListEnum.nextElement();
arrName = iContact.getStringArray(Contact.NAME, Contact.ATTR_NONE);
iContactName = "";
if(arrName[Contact.NAME_FAMILY] != null) {
iContactName += arrName[Contact.NAME_FAMILY];
}
if(arrName[Contact.NAME_GIVEN] != null) {
iContactName += arrName[Contact.NAME_GIVEN];
}
iTelNumber = iContact.getString(Contact.TEL, 0);
} catch (Exception e) {
Logger.logStackTrace(e);
continue;
}
long corePhoneNumber = StringUtils.toCCPhoneNumber(iTelNumber);
// Check Duplicate
if (iPhoneBookList.containsKey(corePhoneNumber)) {
continue;
}
iPhoneBookList.put(corePhoneNumber, iContactName);
}
}
} catch (PIMException ex) {

i my PushSharp service is self hosted in windows service,

Highlighted above is the code line which throws the exception: Not Connected.
Can somebody tell me what can be done to correct this? Thanks a lot.

I don't know what is the problem, but SMS is not received with below code and when I see in the phone memory, app is invalid.
Can anyone correct this code?
I am having a lot of issues with this, it compiles well, but when it is on the real phone, the app says it is invalid,Nokia 2630 supports MIDP 2.0, so not a phone problem.

This may be cause because your sending SMS might not send on the port you defined in your code,
Please look at to this working example.
i found it guys, Thanks for your support, i'm sure i would come back with more queries, i have written a sample receiving sms code with port 5000, It would Help someone in someway,
Before you start,
Right click your application in netbeans and select properties. Now select the application descriptor. select the attribute tab and select the Add button. Give the following in the corresponding fields.
Name : SMS-Port
Value : portno
Now u have registered the port no successfully.
Now again select the push registry tab.
give the following in the corresponding fields.
Class Name : Package name.class name
Sender ip : *
Connection String: sms://:portno
Now u have registered the push registry successfully.

This code works fine on SonyEricsson and Motorola cellphones, but on Nokia it either fails at the beginnig not making any request at all or returns empty response, depending on model.

I am not sure if this will work for you but I had a similar problem and found that specifying a port number made it work (on some older Nokia models). i.e convert:
http://www.mysite.com/my_page.html
to:
http://mysite.com:80/my_page.html
I am getting the error
Missing operand before '=' operator.
when I try and export and the code is running fine in the grid.
Here is the code for the web part. The error only occurs on the rebind. It works fine in the grid itself. Is there any way to narrow down the exact thing it is erroring on?
I am willing to pay for a support / solution to this problem, I just need it to work.

As a follow-up, it appears the problem was that there were NULL values in John's original data. These nulls were causing problems during the data export. Fixing the null values also fixed the Excel export. Original solution on Telerik.com forums:
