Log4j 禁用扫描@webservices

Question

We are trying to user log4j2 ( moving from log4j1 ) but have an issue probably related to the classpath but I couldN,t fix it after multiple tries

We are using a separate module (NbfgLogging) that use a java class to configure LOG4J. The configuration works without an issue but,for some reason, it disable the scan of the @webservice scan. Looking at the console of WAS, the services are not anymore registered COMMONS-LOGGING.PROPERTIES

    org.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.LogFactoryImpl
    #org.apache.commons.logging.Log=org.apache.logging.log4j.Logger
    org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger
    #org.apache.commons.logging.Log=java.util.logging.Logger

I have tried the following that solve the issue of the scan of @webservice. But the looger is not working anymore. I have tried other exclusions... without any succes.

Answer 1

From the error message, it looks like the app located here: PA_Xxxxx.ear/CP-3.4.4-SNAPSHOT.war/ is packaging the JAX-RS 2.0 API here WEB-INF/lib/javax.ws.rs-api-2.0.1.jar the JAX-RS 2.0 API is provided by the WebSphere runtime, and this is causing a conflict. If your application contains JAX-RS code, then you can do one of two things: remove the JAX-RS dependencies from your application and rely on the WebSphere JAX-RS implementation, or if you'd like to use a third-party JAX-RS implementation then you can disable the JAX-RS runtime on Websphere following these directions: https://www.ibm.com/docs/en/was/8.5.5?topic=applications-disabling-jax-rs-runtime-environment
