Currently, TIBCO Fulfillment Provisioning (FP) ex30 located (SW_HOME/distrib/kabira/kpsasample/samples/ex30) provides a sample how to integrate TIBCO FP within TIBCO Fulfillment Order Management. 
This sample also includes a OSSJ Webservice that has a dependency on log4j 1.2.17. 

The aim of this article is to provide all the steps to upgrade this log4j dependency to log4j 2.17.1. 

ex30 is a FP example including :
  * FOM Client Adpater
  * OSS/J JMS-Profile Client Adapter (EMS)
  * OSS/J WS-Profile Client Adapter
  * FPOMS

Environment
***********
In order to deploy OSS/J OrderManagement WS-Profile, the user must export the following variables :
    SAMPLE_JAVA_HOME: a directory where to find JAVA >= 1.6 (uses $JAVA_HOME/bin/java)
    MAVEN_HOME: a directory where to find Maven (uses $MAVEN_HOME/bin/mvn)
    EMS_HOME: a directory where to find TIBCO EMS (uses $EMS_HOME/lib/tibjms*.jar)
    GNU_TAR: a path to the GNU tar command (used to extract Jetty and Symphony)
    USER_WGET: a path the wget command

This article contains resolution and mitigation steps how to upgrade Apache Log4J 1.2.x to Log4j 2.17.x in TIBCO Fulfillment Provisioning sample ex30.

The instructions below explain how to upgrade log4j dependency.

Step 1)
Due to Maven HTTPS restriction, the MAVEN_HOME variable must point to at least maven 3.6.3 version. 

Step2)
The log4j dependency to 1.2.17 is located under the pom_dl_deps.xml. This file is delivered within the ossjomws client adapter. You will find it in SW_HOME/distrib/kabira/kpsa/samples/ca/ossjomws.
The pom_dl_deps.xml is a maven POM file which is used to download the war dependencies from public Maven repository

Here are the steps to be done.
The 3 dependencies "slf4j-api, slf4j-log4j12, and log4j" need to be replaced by "log4j-slf4j-impl and log4j-core". We also recommend to add the javax.jms-api.

remove from pom_dl_deps.xml:
    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-api</artifactId>
      <version>${slf4j-version}</version>
    </dependency>
    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-log4j12</artifactId>
      <version>${slf4j-version}</version>
    </dependency>
    <dependency>
      <groupId>log4j</groupId>
      <artifactId>log4j</artifactId>
      <version>1.2.17</version>
    </dependency>


add in pom_dl_deps.xml:
<dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-slf4j-impl</artifactId>
        <version>2.17.1</version>
</dependency>
    <dependency>
      <groupId>org.apache.logging.log4j</groupId>
      <artifactId>log4j-core</artifactId>
      <version>2.17.1</version>
    </dependency>
<dependency>
    <groupId>javax.jms</groupId>
    <artifactId>javax.jms-api</artifactId>
    <version>2.0</version>
</dependency>

Once modified, the pom_dl_deps.xml should look like the once in attachment.
