How to replace EclipseLink 2.3.2 with EclipseLink 2.5 in WebLogic Server 12c <p>I currrently try to run Docx4j in WebLogic Server 12c. WebLogic Server 12c comes with EclipseLink 2.3.2. </p> <p>There is a similar <a href="http://stackoverflow.com/questions/16934344/docx4j-bad-content-types-xml-with-weblogic-12c">Post</a> describing the situation which unfortunately yield no answer. </p> <p>Docx4j does not work with the JAXB (MOXy) implementation which is part of EclipseLink 2.3.2. I got Docx4j running standalone with EclipseLink 2.5. So I am very confident that using EclipseLink 2.5 with Weblogic Server 12c will solve the issue with Docx4j.</p> <p>How can I replace the EclipseLink Vesion 2.3.2 the WebLogic Server 12c is running on with EclipseLink Version 2.5? </p>
