Unable to use slf4j/Logback on weblogic

ILya CycloneMay 13 2020 — edited May 26 2020

Trying to reuse a library in ADF application.

I have some library code packaged as jar. Library application is created with maven and uses logback.

library pom.xml:

<groupId>ch.qos.logback</groupId>

<artifactId>logback-classic</artifactId>

</dependency>

Library and its logging are working fine in junit tests.

Library is packaged as jar and copied into ADF application ViewController/public_html/WEB-INF/lib.

In ViewController project properties / Library and Classpath this jar is added with Add JAR button.

ADF application starts on integrated weblogic but when library code is called, I'm getting

java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory

Caused by: java.lang.ClassNotFoundException: org.slf4j.LoggerFactory

I tried

<container-descriptor>

<prefer-web-inf-classes>true</prefer-web-inf-classes>

and

<container-descriptor>

<prefer-application-packages>

<package-name>org.slf4j.*</package-name>

in weblogic.xml, but neithed helped.

JDeveloper 12.2.1.3
