I have a problem when running unit test using specs2with scalikejdbc 2.4.1, scalikejdbc-config2.4.1
Here is my code:
object PostDAOImplSpec extends Specification{
sequential
DBs.setupAll
implicit val session = AutoSession
"resolveAll shoudn't have any syntax error" in new AutoRollback {
val postIds = DB readOnly { implicit session =>
sql"select post_id from posts".map(_.long(1)).list.apply()
}
}
DBs.closeAll()
}
Here is logs:
09:11:16.931 [main] DEBUG scalikejdbc.ConnectionPool$ - Registered connection pool : ConnectionPool(url:jdbc:mysql://localhost/bbs, user:root) using factory : <default>
09:11:17.130 [main] DEBUG scalikejdbc.ConnectionPool$ - Registered connection pool : ConnectionPool(url:jdbc:mysql://localhost/bbs, user:root) using factory : <default>
java.lang.IllegalStateException: Connection pool is not yet initialized.(name:'default)
java.lang.IllegalStateException: Connection pool is not yet initialized.(name:'default)
As you can see from the first two of lines, scalikejdbc found database's configuration, but it can't initilize connection pool.
Do you have any idea? Thanks.
The DBs.closeAll() closes your connection pools before running your tests.

I have a Spring Cloud Gateway (eureka client) app that uses Spring Cloud Load Balancer (Spring Cloud version: Hoxton.SR6) and I have an instance of a spring boot app (spring boot 2.3 with enabled graceful shutdown, (eureka client).
When I shutdown a spring boot service and perform a request through the gateway then the gateway throws 500 error (connection refused), instead of 503. 503 appears after a 1-2 minutes.
Can anyone clarify if it is an expected behavior?
It seems that the problem comes from eureka-client (1.9.21 version in my case)
AtomicReference<Applications> localRegionApps isn't frequently updated
Thanks!
UPDATE:
I decided to check deeper this 500 error. The result is that my system (ubuntu) gives this error if the port is not used:
curl -v localhost:9722
Rebuilt URL to: localhost:9722/
Trying 127.0.0.1...
TCP_NODELAY set
connect to 127.0.0.1 port 9722 failed: Connection refused
Failed to connect to localhost port 9722: Connection refused
Closing connection 0
So I put in my application.yml:
spring:
cloud:
gateway:
routes:
- id: my_route
uri: http://localhost:9722/
Then when my request is routed to my_route and none of apps uses 9722 then I get an error:
io.netty.channel.AbstractChannel$AnnotatedConnectException: finishConnect(..) failed: Connection refused: localhost/127.0.0.1:9722

It seems to be an unexpected exception, since it isn't possible to handle it using a circuit breaker or any gateway filter.
Is it possible to handle this error correctly? I would like to return 503 in this case
One of the easiest ways to map particular exception to particular HTTP status code is providing a custom bean of type org.springframework.boot.web.reactive.error.ErrorAttributes. Here is an example:
#Bean
public ErrorAttributes errorAttributes() {
return new CustomErrorAttributes(httpStatusExceptionTypeMapper);
}
public class CustomErrorAttributes extends DefaultErrorAttributes {
#Override
public Map<String, Object> getErrorAttributes(ServerRequest request, ErrorAttributeOptions options) {
Map<String, Object> attributes = super.getErrorAttributes(request, options);
Throwable error = getError(request);
MergedAnnotation<ResponseStatus> responseStatusAnnotation = MergedAnnotations
.from(error.getClass(), MergedAnnotations.SearchStrategy.TYPE_HIERARCHY).get(ResponseStatus.class);
HttpStatus errorStatus = determineHttpStatus(error, responseStatusAnnotation);
attributes.put("status", errorStatus.value());
return attributes;
}
private HttpStatus determineHttpStatus(Throwable error, MergedAnnotation<ResponseStatus> responseStatusAnnotation) {
if (error instanceof ResponseStatusException) {
return ((ResponseStatusException) error).getStatus();
}
return responseStatusAnnotation.getValue("code", HttpStatus.class).orElseGet(() -> {
if (error instanceof java.net.ConnectException) {
return HttpStatus.SERVICE_UNAVAILABLE;
}
return HttpStatus.INTERNAL_SERVER_ERROR;
}
}
}
hava a try to define your custom ErrorWebExceptionHandler.
see:
org.springframework.boot.web.reactive.error.ErrorWebExceptionHandler
org.springframework.boot.autoconfigure.web.reactive.error.DefaultErrorWebExceptionHandler
You should use Cloud Circuit Breaker.
For that:
Declare corresponding starter in your pom:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-circuitbreaker-reactor-resilience4j</artifactId>
</dependency>
Declare circuit breaker in application.yaml
spring:
cloud:
gateway:
routes:
- id: my_route
uri: http://localhost:9722/
filters:
- name: CircuitBreaker
args:
name: myCircuitBreaker
fallbackUri: forward:/inCaseOfFailureUseThis
Declare the endpoint which will be called in the case of failure (a connection error, for example)
#RequestMapping("/inCaseOfFailureUseThis")
public Mono<ResponseEntity<String>> inCaseOfFailureUseThis() {
return Mono.just(ResponseEntity.status(HttpStatus.SERVICE_UNAVAILABLE).body("body for service failure case"));
}

You can try this I think it should solve your problem as it is mostly a missing permission

This is my first time using Scalatra, and I'm using it outside of SBT (building and running using mill). I get the following error which seems to be about a missing dependency.

Here are the dependencies I'm using:
val jettyVersion = "9.4.10.v20180503"
def ivyDeps = Agg(
ivy"org.scalatra::scalatra:2.6.3",
ivy"javax.servlet:servlet-api:2.5",
ivy"org.eclipse.jetty:jetty-server:$jettyVersion",
ivy"org.eclipse.jetty:jetty-servlet:$jettyVersion",
ivy"org.eclipse.jetty:jetty-webapp:$jettyVersion",
)
My JettyLauncher is a striaght copy from the web site, so far, except I changed the resourceBase to be something that actually exists (but it didn't help):
object JettyLauncher { // this is my entry object as specified in sbt project definition
def main(args: Array[String]) {
val port = if(System.getenv("PORT") != null) System.getenv("PORT").toInt else 5001
val server = new Server(port)
val context = new WebAppContext()
context setContextPath "/"
context.setResourceBase("repeater")
context.addEventListener(new ScalatraListener)
context.addServlet(classOf[DefaultServlet], "/")
server.setHandler(context)
server.start
server.join
}
}
My LifeCycle class is also fairly minimal:
class ScalatraBootstrap extends LifeCycle {
override def init(context: ServletContext) {
context mount (new RepeatAll, "/*")
}
}
UPDATE
I changed to using ScalatraServlet instead of ScalatraServlet, but get a similar issue:

I tried putting a WEB-INF/web.xml under repeater as specified above, but same result.
I have searched the net and old question and have no answer that solves my issue.
Fresh install of JBoss 7 1.1 final, I am trying to call EJB using JNDI. It looks like it connects OK but has an error on actual method call.
Here is the Java JNDI code:
InitialContext context = null;
Hashtable env = new Hashtable();
String ejbUrl = TestEJBClient.calculateJbossEjbJndiName ( "TestEJB" , "" , "" , TestEJB.class.getSimpleName ( ) , TestEJBRemote.class.getName ( ) , false );
env.put("jboss.naming.client.ejb.context", true);
env.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming" );
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
env.put(Context.PROVIDER_URL, "remote://localhost:4447");
env.put(Context.SECURITY_PRINCIPAL, "jboss");
env.put(Context.SECURITY_CREDENTIALS, "jboss1");
context = new InitialContext(env);
TestEJBRemote ejbRemote = (TestEJBRemote) context.lookup(ejbUrl);
Customer rtn = ejbRemote.getCustomerByAccountNumber(accountNumber);
Here is the method to calculate the name:
public static String calculateJbossEjbJndiName(String appName , String moduleName , String distinctName , String beanName , String viewClassName, boolean stateful)
{
String rtn = "ejb:"+appName+"/"+moduleName+"/"+distinctName+"/"+beanName+"!"+viewClassName;
if (stateful)
{
rtn = rtn + "?stateful";
}
return rtn;
}

Might be because of the jar files that were used in the client. Check this out :
https://community.jboss.org/thread/227862
I found the solution, It is to add this line to my client code:
jndiProperties.put("jboss.naming.client.ejb.context", "true");
No EJB receiver available for handling
I have working JBoss AS 7 (7.1.1 final) server on localhost with some queue.
And I want to connect to that queue in a desktop application.
So I wrote something like this:
Hashtable env = new Hashtable();
env.put(Context.PROVIDER_URL, "remote://localhost:4447");
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
InitialContext initialContext = new InitialContext(env);
ConnectionFactory connectionFactory = (ConnectionFactory)
initialContext.lookup("RemoteConnectionFactory"); // <- there is it fail
But it results in this exception:
Exception in thread "main" javax.naming.CommunicationException: Could
not obtain connection to any of these urls: remote://localhost:4447
and discovery failed with error: javax.naming.CommunicationException:
Receive timed out [Root exception is java.net.SocketTimeoutException:

javax.naming.CommunicationException: Failed to connect to server
remote:1099 [Root exception is
javax.naming.ServiceUnavailableException: Failed to connect to server
remote:1099 [Root exception is java.net.UnknownHostException:
remote]]]
Of course, I have jbosscall-client.jar in class path.
You need to replace the remote in the PROVIDER_URL with jnp something similar to
### JBossNS properties
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=jnp://localhost:1099
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
properties.put(Context.PROVIDER_URL, "remote://localhost:4447");
properties.put(Context.SECURITY_PRINCIPAL, "hlib");
properties.put(Context.SECURITY_CREDENTIALS, "password1");
InitialContext context = new InitialContext(properties);
ConnectionFactory factory = (ConnectionFactory) context.lookup("jms/RemoteConnectionFactory");
This code workl well if 'application user' for jboss have been added.
