Qlik Talend tESBConsumer component failed to call a web service with: Unable to create message factory for SOAP error

[wei_guo]

The Qlik Talend tESBConsumer component fails to call a web service with the error:

Unable to create message factory for SOAP: Error while searching for service

This may occur after recently upgrading Qlik Talend and moving from JDK 11 to JDK 17. Post upgrade, the following error is encountered when calling a web service using tESBConsumer:

Resolution

To resolve this, the necessary SAAJ implementation and its dependencies must be explicitly provided as separate libraries in the application's classpath. This typically involves including the following:

• Jakarta SOAP API: This provides the API interfaces for SAAJ.
• The dependencies, which can be added to the Studio job by utilizing tLibraryLoad components to load the compatible saaj-impl jar: 
  
  https://repo1.maven.org/maven2/com/sun/xml/messaging/saaj/saaj-impl/3.0.2/saaj-impl-3.0.2.jar
  https://repo1.maven.org/maven2/com/sun/xml/messaging/saaj/saaj-impl/3.0.4/saaj-impl-3.0.4.jar

Cause

The jakarta.xml.soap.SOAPException 'Unable to create message factory for SOAP error', specifically mentions an error while searching for the service [jakarta.xml.soap.MessageFactory]. This indicates a problem with the availability or configuration of the SAAJ (SOAP with Attachments API for Java) implementation.

This issue commonly arises in environments using Java 11 or later, as JAX-WS and its related technologies, such as SAAJ, were removed from the standard Java Development Kit (JDK) in these versions.
