That does not seem to be the case since the Saxon-HE jar is delivered with the embedded zip.

Update Saxon to current release (9.5.x) --------------------------------------- Key: TEIID-3030 URL: https://issues.jboss.org/browse/TEIID-3030 Project: Teiid Issue Type: Feature Request Security Level: Public(Everyone can see) Affects Versions: 8.7 Environment: Apache Maven 3.2.2 (45f7c06d68e745d05611f7fd14efb6594181933e; 2014-06-17T09:51:42-04:00) Maven home: C:\Java\apache-maven-3.2.2 Java version: 1.7.0_60, vendor: Oracle Corporation Java home: C:\Program Files\Java\jdk1.7.0_60\jre Default locale: en_US, platform encoding: Cp1252 OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows" Reporter: Gary Gregory Assignee: Steven Hawkins Our product embeds a Teiid server and provides its own set of 3rd party jar files, one of which clashes with Teiid: we provide Saxon-HE 9.4.0.6 and Teiid provides 9.2.1.5. These two versions are NOT binary compatible. This shows up using the web services connector as a class not found error because some classes have been repackaged between Saxon 9.2.x and 9.4.x. If Teiid updates to the latest version (9.5), so can we, and avoid backporting our Saxon dependencies.
