From the sample code you posted you are using the high-level APIs of the Push Service SDK (as opposed to the low-level APIs). When you use the high-level APIs you must use the Spring Framework to setup your beans rather than trying to instantiate all the objects yourself as your trying to do. As well we use Spring to apply aspect oriented behaviours such as transaction management. It will be very difficult for you to setup all the objects and their dependencies properly as is the case with the error you are getting. Essentially your PushService object is missing a required dependent object that needs to be injected – PushApplicationService. In fact the PushService object itself requires all these dependent objects be set (and each of those objects may have their own dependent object that needs to be set).
* - subscriptionService
* - pushApplicationService
* - pushRequestService
* - pushRequestDetailService
* - papService
* - pushSDKProperties
* - pushIdGenerator
* - pushCountService
* - pushStatsService
So again, if you are using the high-level APIs use Spring Framework to setup your objects. You can use the BeanLocator* classes to retrieve the beans from the Spring Context as convenience (rather than creating the objects yourself using the ‘new’ operator).
If you don’t want to use the Spring Framework and you don’t need the functionality of the high-level APIs then consider using the low-level APIs instead (note: you can use the low-level APIs with Spring too if you want). An example of using the low-level APIs without Spring; you must still setup all the objects correctly:
DefaultPropertyStore store = new DefaultPropertyStore();
store.setTimeToLive(60000);
PushSDKPropertiesImpl pushSDKProperties = new PushSDKPropertiesImpl();
pushSDKProperties.setPublicPpgAddress("https://<cpid>.pushapi.eval.blackberry.com/mss/PD_pushRequest");
pushSDKProperties.setHttpIsPersistent(true);
pushSDKProperties.setHttpConnectionTimeout(60000);
pushSDKProperties.setHttpReadTimeout(120000);
char[] specialChars = { '&', '"', ':', '<' };
pushSDKProperties.setParserSpecialCharacters(specialChars);
pushSDKProperties.setDtdDeclarationPublic("<!DOCTYPE pap PUBLIC \"-//WAPFORUM//DTD PAP 2.1//EN\" \"http://www.openmobilealliance.org/tech/DTD/pap_2.1.dtd\">");
pushSDKProperties.setPropertyStore(store);
HttpClientImpl client = new HttpClientImpl();
client.setPushSDKProperties(pushSDKProperties);
PapService papService = new PapServiceImpl();
papService.setHttpClient(client);
papService.setPushSDKProperties(pushSDKProperties);
List<String> addresses = new ArrayList<String>();
addresses.add(<pin>);
PushMessageControl pushMessageControl = new PushMessageControl(true, new IdGeneratorImpl(), <push app id>, addresses);
pushMessageControl.setPushSDKProperties(pushSDKProperties);
Content papContent = new TextContent("My content");
try {
PushResponse response = papService.push(<push app id>, <push app password>, <push app id>, pushMessageControl, papContent);
System.out.println(response);
System.out.println("Response code: " + response.getCode());
} catch(PushSDKException e) {
e.printStackTrace();
} catch(BadMessageException e) {
e.printStackTrace();
} catch(UnauthorizedException e) {
e.printStackTrace();
}
