I'm trying to integrate Spring Boot (2.6.3) with Camel (3.14.0) to send a simple query to ElasticSearch.
The project is located at https://github.com/saavedrah/springboot-camel-elastic
I have a timer that sends a ElasticSearch query every 60 sec.
However, the following exception is generated:

UPDATE 1
Accordingly with this site CAMEL-17183 the downloaded version of ElasticSearch (7.15.2) does not have the [org.elasticsearch.common.CheckedConsumer] class.
So, how should I update the gradle.properties to get the supported version of ElasticSearch(7.8.0) ?
UPDATE 2
Gradle properties was updated to force the version of ElasticSearch.
configurations.all {
resolutionStrategy {
dependencySubstitution {
substitute module('org.elasticsearch.client:elasticsearch-rest-high-level-client') with module('org.elasticsearch.client:elasticsearch-rest-high-level-client:7.8.0')
substitute module('org.elasticsearch.client:elasticsearch-rest-client') with module('org.elasticsearch.client:elasticsearch-rest-client:7.8.0')
substitute module('org.elasticsearch:elasticsearch') with module('org.elasticsearch:elasticsearch:7.8.0')
}
}
}
And now I'm getting the following exception, I guess it is related with the lack of parameters passed to the query...

Any help is appreciated.
What Huang was telling me was that I should put some query in my timer component body to pass it to the Search operation, something like:
from("timer://foo?fixedRate=true&period=60000")
.process(new Processor() {
#Override
public void process(Exchange exchange) throws Exception {
exchange.getIn().setBody("{\"query\":{\"match_all\":{}}}");
}
})
.to("direct:search");
from("direct:search")
.to("elasticsearch-rest://elasticsearch?operation=Search&indexName=twitter");
Thank you.

I have a Spring Integration Flow starting with a SFTPOutboundGateway. It should get a file from a SFTP server. The file contains Event objects in JSON format. My configuration is:
#Bean
public DirectChannelSpec sftpGetInputChannel() {
return MessageChannels.direct();
}
#Bean
public QueueChannelSpec remoteFileOutputChannel() {
return MessageChannels.queue();
}
#Bean(name = PollerMetadata.DEFAULT_POLLER)
public PollerMetadata defaultPoller() {
PollerMetadata pollerMetadata = new PollerMetadata();
pollerMetadata.setTrigger(new PeriodicTrigger(5000));
return pollerMetadata;
}
#Bean
public IntegrationFlow sftpGetFlow(TransferContext context) {
return IntegrationFlows.from("sftpGetInputChannel")
.handle(Sftp.outboundGateway(sftpSessionFactory(context.getChannel()),
AbstractRemoteFileOutboundGateway.Command.GET, "payload")
.remoteDirectoryExpression(context.getRemoteDir())
.localDirectory(new File(context.getLocalDir()))
.localFilenameExpression(context.getLocalFilename())
)
.channel("remoteFileOutputChannel")
.transform(Transformers.fromJson(Event[].class))
.get();
}
To get a file from the SFTP server I send a message to the gateway's input channel "sftpGetInputChannel":
boolean sent = sftpGetInputChannel.send(new GenericMessage<>(env.getRemoteDir() + "/" + env.getRemoteFilename()));
An SpelEvaluationException is thrown when trying to interprete the given filename. Both fields, remoteDir and remoteFilename are of type String:

What do I wrong?
Okay, the problem is not within the message to get the file but in the configuration of the gateway:
.localFilenameExpression(context.getLocalFilename())
Just to set the local filename as expression is not allowed because dots - often part of the filename - is a SpEL delimiter to separate bean from method name. Hence the expression becomes invalid.
Possible expression would be:
.localFilenameExpression("#remoteFileName")
See its JavaDocs:
/**
* Specify a SpEL expression for local files renaming after downloading.
* #param localFilenameExpression the SpEL expression to use.
* #return the Spec.
*/
public S localFilenameExpression(String localFilenameExpression) {
And here is some code snippet how it works:
private String generateLocalFileName(Message<?> message, String remoteFileName) {
if (this.localFilenameGeneratorExpression != null) {
EvaluationContext evaluationContext = ExpressionUtils.createStandardEvaluationContext(getBeanFactory());
evaluationContext.setVariable("remoteFileName", remoteFileName);
return this.localFilenameGeneratorExpression.getValue(evaluationContext, message, String.class);
}
return remoteFileName;
}
The expression you can provide should somehow be in the context of the currently downloaded remote file. Not sure what is yours static context.getLocalFilename(). You can build a local file name based on the request message and that remoteFileName variable contexts.
See more in docs: https://docs.spring.io/spring-integration/docs/current/reference/html/sftp.html#configuring-with-the-java-dsl-3
The sample over there is like this:
.localDirectoryExpression("'myDir/' + #remoteDirectory")
.localFilenameExpression("#remoteFileName.replaceFirst('sftpSource', 'localTarget')"))
We have a RabbitListener implemented in Kotlin. The method returns Unit, so I dont expect Spring to send a result but we are getting the following error message. It looks like Spring tries to iterprete Unit as the result and send a rabbit message back:

here a simplified version of the RabbitLister:
#Component
class EventHandler {
#RabbitListener(queues = ["someQueue"])
fun receiveMessage(message: Message): Unit {
log.debug("Received message")
}
}
We use Spring Boot 2.4.4, Spring Rabbit 2.3.6 and Spring Framework 5.3.6
debugging the issue, I got the following result:
What version are you using?
This works fine for me (with and without the Unit return type)...
#RabbitListener(queues = ["foo"])
open fun listen(data: String?): Unit {
println(data)
}
Even with : Unit, I see void as the return type and null:

I'm able to consume the same service successfully using PostMan but not through my microservice.
Please assist to advise on this.
I do not know how to edit my own question above as I do not see the edit option hence I'm adding the additional details here to get the resolution of my query.
Controller class:-
#RestController
public class CategorySearchController {
private final CategorySearchService categorySearchService;
#Autowired
public CategorySearchController(CategorySearchService categorySearchService) {
this.categorySearchService = categorySearchService;
}
#GetMapping(path = "/search-category")
public Mono<CategoryResponse> searchCategories(SearchRequest categorySearchRequest){
return categorySearchService
.searchCategories()
.switchIfEmpty(Mono.error(
new EntityNotFoundException("No category matching " + categorySearchRequest.getSearchTerm() + " was found")));
}
}
Service class:-
#Service
public class CategorySearchServiceImpl implements CategorySearchService {
private String baseUrl = "https://demo0954903.mockable.io";
#Override
public Mono<CategoryResponse> searchCategories() {
WebClient webClient = WebClient.create(baseUrl);
return webClient.
get()
.uri("/category-search")
.retrieve()
.bodyToMono(CategoryResponse.class);
}
}
I found the solution for this issue. I need to add the proxy in the webclient as follows:-
private final WebClient webClient;
ReactorClientHttpConnector connector = new ReactorClientHttpConnector(
options -> options.httpProxy(addressSpec -> {
return addressSpec.host(PROXY_HOST).port(PROXY_PORT);
}));
this.webClient = webClientBuilder.baseUrl(BASE_URL).clientConnector(connector).build();
Check your proxy settings. In Spring applications, you can add the following to the VM arguments to set your proxy: -Dhttp.proxyHost=your.proxy.net -Dhttp.proxyPort=8080
I met a similar issue on a scala project. According to the error message, I found IntelliJ took Ant as the compiler which I was expected sbt as the compiler.
Solve the issue by turn on sbt shell use for builds option (Preferences > Build, Execution, Deployment > Build Tools > sbt > sbt projects > sbt shell > check builds )

I'm running JBoss 5.1 GA with JDK 1.6 on Linux and trying to call session bean(jar containing this session bean is deployed on jboss server), Now i want to call this session bean from client, but didnt work.
Java Code at client Side
public class CallingJbossSessionBeanFromClient {
/**
* #param args
* #throws Exception
*/
public static void main(String[] args) throws Exception
{
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
p.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
p.put(Context.PROVIDER_URL, "jnp://182.158.93.41:8080");
Context context = new InitialContext(p);
System.out.println("Successfully Lookup and going to call SessionBean Function deployed on JBoss-5.1.0 Server");
SlsSessiongRemote remote=(SlsSessionRemote) context.lookup("SlsSessionBean/remote");
//SlsSessionBean/remote is RemoteBinding of session Bean
System.out.println("Called");
}
}
where 'SlsSessionBean/remote' is remote binding of session bean deployed on jboss server.
#Stateless
#RemoteBinding(jndiBinding="SlsSessionBean/remote")
but end up with following error

Plz tell me, am i on the right way to call sesion bean from client java class?
I have spent hours looking for solution on Google. However I cannot seem to find anything that holds the hand..try to be more clear, i'm in lack of ideas in this problem, even it sounds like a classic
Plz suggest solution
The solution to this problem is to open the JMX-Console and click on the service=Naming to view the MBean view of the Naming service. Check if the port used is still 1099.....
Changed the URL to jnp://182.158.93.41:1299, the client could communicate with the EJB.
If you are running over JBoss AS 5.x
Here is RMI based JNDI description.
RMI-Port: default -1099 / If dynamic port changed to ports-01 Then Port is 1199
Now, Remaining Things are OK, Modify code ass below
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
p.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
p.put(Context.PROVIDER_URL, "jnp://182.158.93.41:1199");
Another Point is case of accessing
SlsSessiongRemote remote=(SlsSessionRemote) context.lookup("SlsSessionBean/remote");
if - #Stateless(name="SlsSessionBean")
Then Remote JNDI- [SlsSessionBean/remote] and Local JNDI - [SlsSessionBean/local]
if - #Stateless(name="SlsSessionBean", mappedName="SlsSessionBeanGlobal")
Then Remote JNDI- [SlsSessionBeanGlobal] and Local JNDI - [SlsSessionBean/local]
