Issue

  • When attempting to implement a soap client to call remote soap services, the following error occurred: 
    •  Caused by: javax.xml.soap.SOAPException: Unable to create message factory for SOAP: Unable to create SAAJ meta-factory: Provider com.sun.xml.internal.messaging.saaj.soap.SAAJMetaFactoryImpl not found

Environment

  • Liferay DXP 7.3

Resolution

  • The observed error could be the result of the project's missing dependency:
    <dependency>
        <groupId>com.sun.xml.messaging.saaj</groupId>
        <artifactId>saaj-impl</artifactId>
        <version>1.5.1</version>
    </dependency>
  • In some cases, you may also need to add thesaaj-impl-x.x.x.jar to TOMCAT/webapps/ROOT/WEB-INF/shielded-container-lib folder.
  • However, if using an older version than 1.5.1 or requiring lower versions, please create the file ROOT\WEB-INF\classes\META-INF\services\ javax.xml.soap.SAAJMetaFactorywith the following line to provide the fully-qualified name of the SAAJ factory class:com.sun.xml.messaging.saaj.soap.SAAJMetaFactoryImpl
