I am using Spring WebFlux to build a sample WebApplication. I am interacting with the postgres database using spring data's non blocking reactive library r2dbc. I am able to fetch the data and return to the user when the query is returning some result. But when the query is for non-existent values in the database (For ex: I donot have the data for the accountid 112 in my database). I am seeing Null Pointer exception.
#Nullable
#Query("select sum(callrxinboundcount) from account_stats where botname=$1 and starttime > $2 and endtime < $3 ")
Mono<Long> findSumOfCallReceivedInboundCountByDurationForBotName( String accountId, Long startTime, Long endTime);
java.lang.NullPointerException: data

How can I handle this null pointer exception and return zero incase the value does not exist in the db?
You can change your query like this.
SELECT SUM(IFNULL(callrxinboundcount, 0)) FROM account_stats WHERE botname=$1 AND starttime > $2 AND endtime < $3
That’s one way I can think of.
Remove #Nullable
You can consider Mono is the Optional in the Reactive stack.
In your controller or exception handler, it is easy to handle the non-existence case.
For example,
use switchIfEmpty to return result directly.
use a standalone ExceptionHandler to handle the exception.

I have the following Class that extends ModifyResponseBodyGatewayFilterFactory: -
#Component
public class ModifyResponse extends ModifyResponseBodyGatewayFilterFactory{
public ModifyResponse(List<HttpMessageReader<?>> messageReaders, Set<MessageBodyDecoder> messageBodyDecoders, Set<MessageBodyEncoder> messageBodyEncoders) {
super(messageReaders, messageBodyDecoders, messageBodyEncoders);
}
#Override
public GatewayFilter apply(Config config) {
config.setRewriteFunction(String.class, String.class, (exchange, originalContent)->{
JSONObject response = new JSONObject(originalContent);
response.remove("key");
return Mono.just(response.toString());
});
return super.apply(config);
}
}
My Controller class running on another port is as follows: -
#RestController
public class HomeController {
#PostMapping(value = "/home", produces = "application/json")
public ResponseEntity<Object> home(#RequestBody Object request, #RequestParam(value = "param1") String param1){
JSONObject response = new JSONObject(request);
return ResponseEntity.status(HttpStatus.OK).body(response.toString());
}
}
When I pass a request to the controller that is supposed to go and comeback through the gateway filter, I get the following error: -

Regardless of what I change the inclass or outclass type to in the setRewriteFunction(), it always returns the same error.
Till date my project was working fine, but when I added getlocator package to fetch user current data. returning a error like. Thanks in advance
An exception has occurred in the compiler (1.8.0_242-release). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates.

This solution works for me. In android --> app --> build.gradle
compileSdkVersion 30
defaultConfig {
minSdkVersion 21
targetSdkVersion 29
}
geolocator package version was geolocator: 7.6.2 (don't user ^ symbol)
I have a GRPC service with POST, DEL and GET methods exposed thru HTTP endpoints. I also have an Istio proxy for my pod. When I call these APIs thru curl/postman, the DEL and GET requests go through and I get a response from my service, whereas when I call the POST API with a valid JSON content in the message body, the API request seems to be rejected by Istio NettyServerHandler, as shown by the stack trace.
Please let me know what is the issue here and how it can be fixed. The content-type header in my POST request is set to application/json.

2021-11-15 15:39:05.705 WARNING: Exception in onDataRead()
2021-11-15 15:39:05.704 Nov 15, 2021 7:39:05 AM io.grpc.netty.NettyServerHandler onDataRead
The issue got resolved as it was found that the JSON document in my request body was invalid and hence the Json to GRPC translator used by istio failed while converting it to the relatd GRPC format.

Please change the link to anonsvn.jboss.org to use https (the link pointing to the XSD schema). Looks like anonsvn.jboss.org was migrated to https, so no http connections allowed now.
The way that I found to solve this problem was setting this property to false, that's because drools validate the schema, so, doing this it will not validate it.
-Ddrools.schema.validating=false
Changing to https works. We had locally copied the change set schema to classpath resource and validate changeset document against local schema.
I have two packages. One package contain two classes namely Question and Options both are implemented by a serialization.
When i try to invoke the objects for these classes in another classes which is located in an another package showing an Serialization Exception.
What to do for that?
The Exception is
Exception while dispatching incoming RPC call
com.google.gwt.user.client.rpc.SerializationException: Type 'com.fes.client.Exam.Valid.Options' was not included in the set of types which can be serialized by this SerializationPolicy or its Class object could not be loaded. For security purposes, this type will not be serialized.: instance = com.fes.client.Exam.Valid.Options#9905e0
