Make sure you have correct version (2.x) of XmlBeans on you classpath.

  • xmlbeans 2.3 is the minimum version to work with Apache POI, anything newer than that ought to work fine too – Gagravarr Aug 30 '12 at 12:28

See javadoc :

XmlOptions setSaveAggresiveNamespaces() : Deprecated. replaced by setSaveAggressiveNamespaces() in 2.0. You might be using Apache XMLBeans 1.x library. Either use latest release(recommended) or change method call to setSaveAggresiveNamespaces()

Check that your version of xmlbeans is correct. If you are using maven, finds that there is no other unit that contains a different version of xmlbeans. (Use mvn dependency: tree)
