Hi,

I have created one Restful jpos projects using jetty, hibernate and jpos ee.

I am able to start my q2 and able to hit to my webservice. However when i tried to fetch the data from database table, i received the below exception of "can not be cast"

Kindly check below q2 logs for more details

That's seem to be an error on your hibernate setup. Is more a Hibernate issue than a jpos one

Maybe there's a chance someone here can help you out pinpointing the issue but I think you would have more luck in a Hibernate specific forum.

Best regards

Hi Chill,

How can i get that 2 different class loader are getting load for one Class.

As i have integrated my hibernate database models in jpos ee, rest jetty based project.

I have created the project using http://jpos.org/doc/tutorials/jpos-rest.pdf

and integrated hibernate into this.

Thanks,

I don't know, are you trying to use sessions across threads? (just brain storming)

Probably a missing `providedCompile` instead of `compile` in the dependencies.

Hi Chhil,

yes, trying to use db sessions across threads, as it's rest webservice, it has controller and multiple web api's.

below is the code of my Conrtoller.java

import javax.ws.rs.GET;

import javax.ws.rs.POST;

import javax.ws.rs.Path;

import javax.ws.rs.Produces;

import javax.ws.rs.core.MediaType;

import javax.ws.rs.core.Response;

import org.jpos.transaction.Context;

import org.jpos.util.Log;

import com.google.gson.Gson;

@Path("/transaction")

public class TxnController {

private Log log = Log.getLog("Q2", this.getClass().getSimpleName());

@POST

@Produces({ MediaType.APPLICATION_JSON })

@Path("/txnHistory")

public String txnHistory(String txnJson) {

Gson gson = new Gson();

DB db = new DB();

TxnHistoryApi txnHistoryApi = gson.fromJson(txnJson, TxnHistoryApi.class);

Context ctx = createContext(getClass().getSimpleName().toLowerCase() + "::get");

ctx.put(Constants.DB, db);

ctx.put(Constants.HISTORY_REQ, txnHistoryApi);

TxnHistoryService txnHistoryService = TxnHistoryService.getInstance();

txnHistoryService.executeService(ctx);

String response = gson.toJson(txnHistoryApi);

return response;

}

@POST

@Produces({ MediaType.APPLICATION_JSON })

@Path("/register")

public String register(String txnJson) {

String response = "";

Gson gson = new Gson();

UserRegisterApi registerApi = gson.fromJson(txnJson, UserRegisterApi.class);

DB db = new DB();

Context ctx = createContext(getClass().getSimpleName().toLowerCase() + "::get");

ctx.put(Constants.DB, db);

ctx.put(Constants.REGISTER_REQ, registerApi);

UserRegistrationService regService = new UserRegistrationService();//.getInstance();

regService.executeService(ctx);

response = gson.toJson(registerApi);

return response;

}

@GET

@Produces({ MediaType.APPLICATION_JSON })

@Path("/echo")

public Response echoGet(String txnJson) {

Map<String, Object> resp = new HashMap<>();

resp.put("success", "true");

Response.ResponseBuilder rb = Response.ok(resp, MediaType.APPLICATION_JSON).status(Response.Status.OK);

return rb.build();

}

Thanks.

You are certainly missing a couple providedCompile (see the 3 'compile' you have there), but the problem is probably related to the fact that your classes are probably within src/main/java on the same module you're building the war, so they end up both in the main 'jar' as well as the 'war'.

If you use the multimodule template ('multimodule' branch in the jPOS-template project) you can use a different module for your entities and for your app (see the 'testbed' module in jPOS-EE, in puarticular its 'build.gradle').

As an alternative, you can exclude some files from the war, (see https://github.com/jpos/jPOS-EE/blob/master/modules/testbed/build.gradle#L33-L45) so that your entities just remain in the main jar and not in the war.

Hi Alejandro,

Below is my updated build.gradle

war {

classpath = configurations.runtime

webInf {

into('classes') {

from sourceSets.main.output

exclude('**/com/web/model/*.class')

exclude('**/com/web/dao/model/*.class')

exclude('**/com/web/runtime/*.class')

exclude('**/com/web/service/*.class')

exclude('**/com/web/util/*.class')

}

apply from: 'jpos-app.gradle'

installApp.dependsOn('war')

dist.dependsOn('war')

Now my war doesn't contain the customized classes.

Now below is the exception which is getting now:

Hi:

This is happening to you because you have chosen to load Jetty as a QBean from within Q2, but some of your code is loaded from within the 'war' classloader. Consider loading all your classes from within the Q2's classloader and not Jetty's.

Can you more elaborate on Q2's classloader? How can i load my classes from within Q2? so that I can accept the request on webservice.

Thanks.

Hi:

Java loads Q2 using it's base classloader.
When deploying Jetty, Q2 creates its own nested classloader for it, so it can control its lifecycle (unload it)..
Jetty in turn by default, creates a new nested classloader for loading the contents of WEB-INF/classes and WEB-INF/lib/*.jar in your war.

So these classloaders being nested, create a dilema... A class can only access other classes loaded by its own classloader or any of its parents (by delegation - remember they are nested). So Q2 cannot access the classes that you put in your WAR's WEB-INF/classes or any of the jars you put in WEB-INF/lib.

Easiest fix for you would be to get rid of the 'war' altogether and just deploy the jetty webapp contents with a plain descriptor (cfg/jetty.xml). Of course, it's 2018 and people don't entertain this kind of torture and just go for Spring Boot, nonetheless it's the way this works today with the Jetty module.

Are you deploying Jetty using the 90_jetty.xml ?

Here the q2 classloader loads the jetty server (embedded) via a regular qbean Jetty.java.

Jetty module can be found at

Hi Chhil,

Yes, I am deploying Jetty using 90_jetty.xml. If i removed it, then how will it my descriptor will be deployed?

Thanks.

Not asking to remove it.

My setup uses jetty xml deploy (custom jetty.java, to set up paths and mapped resources, so I don't do it using the xml descriptors, which I feel shouldn't matter) , no war file, the classes exist in the modules, are compiled and built into the regular jar. Q2 loads the classes.
