I am having issue while connecting to Spring Boot RSocket application over TCP. The client when using RSocketRequester works fine but when I try to connect using RSocketFactory client it keep getting errors. Code below.
RSocket rSocket = this.client = RSocketFactory
.connect()
.mimeType(WellKnownMimeType.MESSAGE_RSOCKET_ROUTING.toString(), MediaType.APPLICATION_JSON_VALUE)
.frameDecoder(PayloadDecoder.ZERO_COPY)
.transport(TcpClientTransport.create("localhost", 7000))
.start()
.block();
Flux<Payload> s = rSocket.requestStream(DefaultPayload.create("1234", "socket"));
s.subscribe();
This gives error as below:
java.lang.IndexOutOfBoundsException: readerIndex(1) + length(115) exceeds writerIndex(6): AbstractPooledDerivedByteBuf$PooledNonRetainedSlicedByteBuf(ridx: 1, widx: 6, cap: 6/6, unwrapped: PooledUnsafeDirectByteBuf(ridx: 27, widx: 27, cap: 1024))

This particular error is as I understand is because of netty message wrapping (from other threads on stackoverflow) but how to solve it?
The server is Spring Boot 5+ RSocket but the client is only using RSocket-Java.
The problem is inside mime types.
In your case server awaits CBOR but you proceed application/json
The code solution: change the way of RSocketRequester initialization as at the example below and you client with be sending CBOR you can see at by enabling debug: logging.level.io.rsocket.FrameLogger: DEBUG. That's all for hello world, no need custom strategies or factories implementations on the client-side
#Bean
RSocketRequester rSocketRequester(RSocketStrategies strategies) {
return RSocketRequester
.builder()
.rsocketStrategies(strategies)
.connectTcp("127.0.0.1", 7000)
.retry(5)
.block();
}
Btw, I didn't reach the solution with JSON on both side even with custom Encoder & Decoder on both side. I guess the reason here is that there is no CBOR to Jackson converter and only vice versa: org.springframework.http.codec.cbor.Jackson2CborEncoder
From this, use the following to generate metadata.
CompositeByteBuf metadata = ByteBufAllocator.DEFAULT.compositeBuffer();
RoutingMetadata routingMetadata = TaggingMetadataCodec.createRoutingMetadata(ByteBufAllocator.DEFAULT, List.of("/route"));
CompositeMetadataCodec.encodeAndAddMetadata(metadata,
ByteBufAllocator.DEFAULT,
WellKnownMimeType.MESSAGE_RSOCKET_ROUTING,
routingMetadata.getContent());
i have simple bpel process that recieve input , assign input to call remote webservice , then assign response to output variable
the problem is when assign the respose from the remote webservice to the output of the bpel process i get the following exception

also i noticed strange problem
when i'm doing the mapping from remote service respone to the bpel output , jdevloper make the line from the part1 to payload , and i need to write ns2:creditcardstatus (which is the response ) by myself
also the composite xml show the following warnings :
you got (selectionFailure ) exception, that means the creditcardStatus is empty to avoid this issue you can add ignoreMissingFromData="yes" in the assign component as below
<copy ignoreMissingFromData="yes">
<from>$inputVariable.payload/ns3:documentId</from>
<to expressionLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0">$Invoke_Notifications_InputVariable.request/ns3:documentId</to>
</copy>
As I had already few issues with combination Nomin, Eclipse and Groovy (see link1 and link2), I am again struggling with it.
My application works with JUnit Tests, both in Console via Gradle and Eclipse. But now it doesn't want to work when executing SpringBoot-Main class. Either in Eclipse nor with gradle bootRun on Console or Eclipse Gradle Task => Same Exception

UPDATE:
The following CodeSnippet from Nomin.class works as expected when running under Test. When running via bootRun the else if on line 220 is false, what should be true.
On line 220 we have pm.sideB.isAssignableFrom(key.source) what should result to true, because pm.sideB is type of Coin, and key.source is type of Coin (see Screenshots).
Your problem is caused by spring-boot-devtools runtime dependency. When you run your application with a debugger you will find out that classes net.hemisoft.ccm.porter.Coin and net.hemisoft.ccm.domain.CoinOnMarketPlace are loaded twice using two different classloaders:
sun.misc.Launcher$AppClassLoader
org.springframework.boot.devtools.restart.classloader.RestartClassLoader
This is why following part of code evaluates to false:
else if (pm.sideB.isAssignableFrom(key.source) && pm.sideA.isAssignableFrom(key.target)) result.add(new MappingWithDirection(pm, false));
Even though key.source and pm.sideB seems to be the "same" classes, they are not equal because they are being managed by two different classloaders. Classes with the same canonical name are only equal inside the same classloader. And this is why your unit test works like a charm - there is no spring boot devtools involved and if you go with debugger to Nomin.java:(line 220) while running unit test, you will see that key.source and pm.sideB hold a reference to the same class inside one classloader so this expression evaluates to true and the mapping you defined is being used. Otherwise nomin tries to generate mapping automatically (it can be disabled with Nomin.disableAutoMapping()) and in this case, it uses default introspector - ReflectionIntrospector. This one causes issues with Groovy classes as we already figured out in one of your previous SO questions.
Solution
Disable spring-boot-devtools or disable restarts or at least try to exclude your domain classes from restarting application. You can check Spring Boot Devtools docs to see how to do it. I would just get rid of it - as you can see it makes your application running differently in your dev environment, so you can never be sure how it behaves when running live.
My Webproject code is deployed on weblogic 12c server.

Sometimes however the page Home.jsp does load and some times throws error .
Home.jsp calls the Home Servlet and then diospatcher redirects

I develop a cayenne project with a java rich client and an remote obejct persistence server. If i the rich cient connects with a Cayenne-ROP-Server that is deployed on the same machine on localhost (on Jetty from maven goal like explained inside the cayenne rop tutorial) everythings fine:
ClientConnection clientConnection = new HessianConnection("http://localhost:8080/rop.server /cayenne-service",
"cayenne-user", "secret", SHARED_CAYENNE_SESSION_NAME);
DataChannel channel = new ClientChannel(clientConnection);
ObjectContext context = new CayenneContext(channel);
List<Object> someEntities = context.performQuery(allMovies);
If i change the url that i want to connect to in the first line to a non local host (Tomcat7 on ubuntu) then everything works till it comes to the 4th line:
List<Object> someEntities = context.performQuery(allMovies);
Then i get the Error "No session associated with request"
Here is the full Output of the Client:

I use Apache Cayenne 3.0.2, Apache-Tomcat 7.0.29 and Java 7 sdk
THX in advance for every Help
PS. Maybe the local Jetty server handles things in another way as the Tomcat Server on remote unix machine.
Edit:
After the hint given by Andrus in the answer below i added an SessionListern that looks like this:
public class HttpSessionListenerLogImpl implements HttpSessionListener {
private final static Logger LOGGER = Logger.getLogger(HttpSessionListenerLogImpl.class.getName());
#Override
public void sessionCreated(HttpSessionEvent hse) {
LOGGER.log(Level.SEVERE,
"!__Session created with ID: " + hse.getSession().getId());
LOGGER.log(Level.SEVERE, "!__Session created by: " + hse.getSource());
LOGGER.log(Level.SEVERE, "!__Session Attributes: " + hse.getSession().getAttributeNames());
LOGGER.log(Level.SEVERE, "!__Session max inactivity: " + hse.getSession().getMaxInactiveInterval());
LOGGER.log(Level.SEVERE, "!__Session context: " + hse.getSession().getServletContext().getServletContextName());
}
#Override
public void sessionDestroyed(HttpSessionEvent hse) {
LOGGER.log(Level.SEVERE, "!__Session killed with ID: " + hse.getSession().getId());
LOGGER.log(Level.SEVERE, "!__Session killed by: " + hse.getSource());
LOGGER.log(Level.SEVERE, "!__Session Attributes: " + hse.getSession().getAttributeNames());
LOGGER.log(Level.SEVERE, "!__Session max inactivity: " + hse.getSession().getMaxInactiveInterval());
LOGGER.log(Level.SEVERE, "!__Session context: " + hse.getSession().getServletContext().getServletContextName());
}
So this listern gives me the following output when executing the 4 lines of code statet on top of this Question:

Here you can see there is a session that gets created and there is no session that gets killed. So why does the ObjectContext from my line of code
List<Object> someEntities = context.performQuery(allMovies);
does ignore the session. Do i have to set it explicitly before doing a query? What is the standard initializing code on the client side to access an remotly deployed cayenne server. Does it differ from the one given inside the cayenne rop tutorial?
THX in advance.
Edit:
I upgraded to cayenne 3.1B1 hoping to get rid of this error, but same Situation here: "No session..." when trying to send a query.
I also setup a tomcat on localhost and configured it the same as the remote is. Same Problem here "No Session..." when trying to send a query.
So the Jetty on localhost is the only one that takes the 4 line init code from above and holds the session for every following query. So here is my Question. Does anyone on this planet ever tried to deploy a cayenne rop server on a tomcat and succeeded?
THX in advance for every little hint.
Edit:
So i did a litte bit of server side debugging on my local tomcat7.
1.Client executes line 2 of code from above:
DataChannel channel = new ClientChannel(clientConnection);
on the Serverside my session listener gets triggerd and tells me a session has been created with id: B6565298F222294F601B76333DBE4911
2.Client executes line 3 from above:
ObjectContext context = new CayenneContext(channel);
On the server side the method of class org.apache.cayenne.remote.service.HttpRemoteSession gets called:
/**
* Returns a ServerSession object that represents Cayenne-related state associated
* with the current session. If ServerSession hasn't been previously saved, returns
* null.
*/
#Override
protected ServerSession getServerSession() {
HttpSession httpSession = getSession(true);
return (ServerSession) httpSession.getAttribute(SESSION_ATTRIBUTE);
}
a new session gets created by line one of this method. Its ID is: ECC4A81D6240A1D04DA0A646200C4CE6. This new Session contains exactly one attribute: the key is "org.apache.cayenne.remote.service.HttpRemoteService.ServerSession" and the value is (who guessed it?) the session created before in step 1
What makes me wonder is that my serveltListener dont gets triggerd though a new session gets created.
3.Client executes line 4 from above
List<Object> someEntities = context.performQuery(allMovies);
at the serverside now the getServerSession() method is called again. This time also a new session gets created (why?). And this session does not contain any attribute. So the line "return (ServerSession) httpSession.getAttribute(SESSION_ATTRIBUTE);" inside the method getServerSession() returns null and exactly this triggers the exception "No Session associated with request".
So why is the cayenne serverside creating e ne session and doesnt use the old one created befor? Do i have to explicitly send the session within the query?
Edit:
I made screenshots from the netbeans http-monitor while running the four lines of code from above:
This is an issue between Cayenne ROP and newer containers:
https://issues.apache.org/jira/browse/CAY-1739
Here is a Tomcat solution - create context.xml file with the following contents, and place it in META-INF/ of your webapp:
<Context>
<Valve className="org.apache.catalina.authenticator.BasicAuthenticator"
changeSessionIdOnAuthentication="false" />
</Context>
