kandi X-RAY | msf4j Summary

msf4j is a Java library typically used in Architecture, Microservice applications. msf4j has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has high support. You can download it from GitHub, Maven.

WSO2 Microservices Framework for Java (MSF4J) is a lightweight high performance framework for developing & running microservices. WSO2 MSF4J is one of the highest performing lightweight Java microservices frameworks. The following graphs show the throughput, memory consumption & latency characteristics of MSF4J against other microservices frameworks. An echo service which accepts a 1KB request & echoes it back directly and using a temp file was developed for the respective frameworks, and requests were sent for different concurrency values. The test was repeated for each concurrency value for each framework and the average throughput was calculated. Tests were run out of the box without any tuning on 32 core 64GB server in JVM v1.8.0_60 with default configuration. Memory usage for each framework was observed after running the 1KB payload echo microservice on each framework & sending a number of requests at different concurrency levels to each service. The graph above shows the averaged out values after several runs for each framework. Latency results was observed using the Apache bench provided percentile values. Results were plotted for various concurrency levels the simple echo test. Tests were run out of the box without any tuning on 32 core 64GB server in JVM v1.8.0_60 with default configuration.

How to configure WSO2 API Manager Analytics

Asked 2021-Feb-22 at 03:30

I'm new to WSO2, and I'm trying to configure a single node WSO2 API Manager with Analytics using mysql as the RDBMS on my local machine (ubuntu).

I've successfully configured the API Manager to use mysql as the RDBMS using the official documentation page here, however I can't configure the Analytics to use mysql as the RDBMS.

I've followed the official documentation related to Configuring APIM Analytics, downloaded the Connector/J 8.0.23 from MySQL official website and copied it to the lib directory, and here's my db-related configuration on /conf/worker/deployment.yaml file:

Sample Pickup dispatch web app giving CORS issue when making backend api calls in WSO2 IS 5.10

Asked 2020-Jun-10 at 06:18

I'm testing the pickup dispatch sample web app for WSO2 Identity Server 5.10 https://is.docs.wso2.com/en/5.9.0/learn/configuring-access-delegation-with-oauth2/

Everything is set up as mentioned in the documentation. When clicking 'Add' the request cannot be completed because it is being blocked dues to CORS policy.

...

ANSWER

Answered 2020-Jun-10 at 04:30

From your updated stack trace, I can see that the issue occurs when the backend service trying to make an introspection call to the WSO2 Identity Server. This introspection call uses the token it's introspecting as the authorization for the call it self. For this to work, the token needs to be obtained with the scope internal_application_mgt_view. But at the moment, the pickup-dispatch application requests tokens with only the openid scope.

To fix this, open the dispatch.properties file in /pickup-dispatch/WEB-INF/classes directory in a text editor and edit the scope property as shown below.
