XSLT-SXS: org/xml/sax/XMLFilter violates loader constraints

Hi all,

I’m trying to use the XSLT Server X-Tension but I always get the following message:

INOSXE7114: Java error: java.lang.LinkageError: Class org/xml/sax/XMLFilter violates loader constraints

I think it’s a version problem of the jar files I’m using:

XP: from tamino distribution (
JAXP: from tamino x-plorer dir
XALAN: 2.4.D1 (same problem occurs with SAXON 6.5.2)

The X-Tension documentation doesn’t tell me which versions to use.

Does anone know the right versions?


Hi Michael,
The JVM used by Tamino to execute SXS has restrictions to prevent falseful usage and harm the Tamino server. Exchanging the classloader and the security is among these restrictions.
Class org/xml/sax/XMLFilter of Your XALAN/SAXON implementation obviously violates these restrictions.
Please use the common SAG methods to contact the Tamino support on the issue.
Best regards, Michael K
