wso2 / msf4j Goto Github PK

Please provide information to change default netty port (8080) when already occupied.

creating a resource with @options (javax.ws.rs) annotation gives a "405 Method Not Allowed" Response, the http OPTIONS request is not recognized.

In my case this was needed when using a AngularJS web app the browser sends an additional http OPTIONS request to check for CORS.

We can reduce the pack size if we remove the guava dependency and replace those functionalities with Java 8.

With the current hot deployment implementation, all services will always get exposed on all ports. We need a mechanism to specify that certain microservices get exposed only on certain ports.

This is an improvement for the enhancement #323

Hi All,

I'm very interested with WSO2 Microservices Server (WSO2 Microservice Framework for Java), It's awesome! ^_^

I'm looking for a sample with manipulate database table (CRUD), but i can't found it. Can you add a sample with manipulate mysql database table (CURD) ? I think it would help everyone.

Thanks,

In HelloWorld example you have test url: http://localhost:8080/service/wso2 (which is invalid) while correct seems like http://localhost:8080/service

Implement a mechanism to prioritise the existing interceptors so that interceptors would execute based on a certain order defined by the developer. Interceptors without a priority defined should have a default priority.

I'm following tutorial to run Stockquote in osgi mode, but i get the error Caused by: java.lang.NoClassDefFoundError: org/springframework/aop/support/AopUtils . it's look like Spring AOP not found in msf4j-core.

Hello.
We using here WSO2 DSS and identity server.
Using WebLogic too.
I should deploy the .jar to WebLogic ? or configure .war ?

Tks

please check with mail [1].

Metrics are useful, but do we have a reporter that could talk to Graphite ?
https://graphite.readthedocs.io/en/latest/

If not, how do we integrate that ? Can you update your metrics sample with one such Graphire integration too ?

Could you give us a sample using Ember.js or or other single page application(SPA) javascript framework ?
And use JWT for User Authentication.

I did the setup for sample Helloservice .
When I was giving mvn package it shows below error:

In MSF4J 2.0.1-SNAPSHOT when trying to run the micro service in https as stated in docs

it gives the following error

If we return a self referential object it will throw a StackOverflowError.

We can avoid this if we use https://github.com/google/gson/blob/1d9e86e27c97cd85d898104b4ac42bb487d0d7d0/extras/src/main/java/com/google/gson/graph/GraphAdapterBuilder.java

May need to consider the performance impact of introduction though

I have a already created JSON string. But if I try to return that from a MS the framework re-serializes it.
eg:

String json = "{\"a\":\"b\"}";
return Response.ok(json, "application/json");

expected = {"a":"b"}
actual   = "{\"a\":\"b\"}"

Is there a workaround to get the expected?

It seems msf4j does not support JSR 349 yet.

The following code give nulled User:

    @POST
    @Path("/create")
    @Consumes(MediaType.APPLICATION_JSON)
    public String create(@Valid User user) {
        println "User: " + user
        return "success"
    }

I would love to see bean validation in msf4j.

Thanks!

Hi Team!

Congratulation for the new Session Feature! ^_^

btw, could you please add "Session Store Mechanism" by using RDBMS and Redis?

I think it would help developer to make scalable microservice application. Personally, we need it for scaling our microservice application in a high availability environment.

how to use jpa module service in angularjs. i tried using #http but it didn't work.can you help me?i want to know how to use microservice in angular front end.
thank you.

When the concurrency increases, Service calls fail when doing chain internal calls.

We need to implement Websocket and Server-Sent Events (SSE) support for the MSF4J

We need to support the mode where the MSF4J service jars are copied to a directory and then a deployer deploys those services

I'm not sure if this is an issue with MSF4J but I think it probably is.

I'm running a performance test on Ubuntu 16.04.

I'm using siege 3.1.4, with the following command line

siege -b -q -c 10 -r 10000 http://localhost:8080/purchase

I have a microservice using redis as a backend. The microservice code is available:

git clone https://github.com/pzfreo/POResourceComplete

You can simply clone / mvn clean install and then run the jar , as long as you have redis running.
mvn clean install
java -jar target/POResource-1.0.0.jar

The same code also runs under Jetty/Jersey. You can build that in the same directory with
gradle shadowJar
java -jar build/libs/POResourceComplete-all.jar

When I run under MSF4J I get a lot of failures.
When I run under Jetty/Jersey it works ok.

It might still be my Linux, but its highly repeatable and only happens with the MSF4J server not the Jersey server.

Send a GZIP request to stockquote sample. This will throw HTTP 500 error. The reason is the message that gets from carbon-transport doesn't decode the request, hence MSF4J can't process the message.

• Does it support only SOAP or REST Support is also there?
• Could you please clarify to what level REST support is there?

Thank you.

We can use the kernel 5.2.0-SNAPSHOT based carbon kernel test container and implement OSGi test for MSF4J

I tried to add msf4j into my microservices performance benchmarks but got the following error under load. I think it must be some tuning parameters that I missed. I am wondering if someone here can help. MSF4J looks pretty good and it has potential out perform most of the microservies frameworks as it is netty based.

Here is the repo with source code.

https://github.com/networknt/light-java-example/tree/master/performance/msf4j

Hi guys,

First of all I would like to congrats the team for the launching of msf4j framework. Personally I think the framework is promising. Being one of the first java microservices framework based on jax-rs (or the subset) which is JEE the facto REST API standard ...

However I found out that if you send any unhandled request to the msf4j service, the service will thrown an unhandled exception and stop working. Any subsequent request will simply ignored/rejected. Even the one with correct URL pattern which has specific handler method assigned for it.

This could be a special case which is only happen in my case only, but nevertheless I need to create a customized exception handler that could catch this unhandled exception. Within jax-rs specification, one way to achieve that is by creating a custom ExceptionMapper class.

My questions are :

• Does msf4j jax-rs implementation support addition of custom ExceptionMapper ?
• If it does, how can I actually incorporate my custom ExceptionMapper class into the framework ? Will the inclusion of @produces annotation in my custom class alone enough ?
• If it does not support custom ExceptionMapper, what is the right way to prevent unhandled exception in msf4j ?

Thanks in advanced.

Kind regards,
Ahmad R. Djarkasih.

It would be nice to have a global exception mapper where we can handle HTTP 500 which happen prior to service call

Hello,
I want to try the new msf4j framework but there is an error when trying to create the project with maven archetype.
It tells that archetype version 2.0.0 does not exist.
I've tried with version 1.0.0 with success but the generated code does not match the tutorial.

Regards

Samuel

Hi !

The version of msf4j in at least https://github.com/wso2/msf4j/blob/release-2.1.0/samples/spring-helloworld/pom.xml is incorrect :

org.wso2.msf4j
msf4j-spring
2.1.1-SNAPSHOT

It should point to version 2.1.0 I think.

Best regards

When there are several transports, some services are not getting registered with all the carbon transports.

can i know how check jpa service.in hello service "http://localhost:8080/hello/wso2" output was "hello wso2".like wise how can i verify that jpa module is working.........

this is not an issue.if there is any community to take help please send me that also.

thank you.

We are going to use below snippets in order to do POST request with 201 response. We want to send the Created resource location through the Response. Once we implement that we came up with below stack trace.

I have created a new project in eclipse based on the archetype as specified in the documentation. When this has been created I get the following errors in the pom.xml file:

Multiple annotations found at this line:
  - Missing artifact commons-io.wso2:commons-io:jar:2.4.0.wso2v1
  - Missing artifact org.wso2.carbon.transport:org.wso2.carbon.transport.http.netty:jar:2.1.2
  - Missing artifact org.wso2.carbon.messaging:org.wso2.carbon.messaging:jar:1.0.4

These packages are declared in the parent pom.

I have tried forcing an update of the snapshots as well as running maven clean install but these fail with the same errors. I have looked in the central maven repo but can't find these packages.

I am using Eclipse neon with Java 1.8.

I want to create Filter to logging any payload request response in msf4j, but when i used @Provider to create filter, it doesn't work.

I see the below error when perf-benchmark/run-test.sh is run:

ab -k -p 1kb_rand_data.txt -c $i -n 1000000 -H "Accept:text/plain" $service
ab: wrong number of arguments
Usage: ab [options] [http[s]://]hostname[:port]/path
