Try this: Rename the xerses.jar to xersesold.jar (under orion) Copy cocoons xerses.jar to the orion lib. Unpack the cocoon.jar. Change the cocoon.properties to this: processor.xsp.logicsheet.context.java = file://localhost/orion/default-web-app/web-inf/lib/org/apache/cocoon/processor/xsp/library/java/context.xsl processor.xsp.logicsheet.cookie.java = file://localhost/orion/default-web-app/web-inf/lib/org/apache/cocoon/processor/xsp/library/java/cookie.xsl processor.xsp.logicsheet.global.java = file://localhost/orion/default-web-app/web-inf/lib/org/apache/cocoon/processor/xsp/library/java/global.xsl processor.xsp.logicsheet.request.java = file://localhost/orion/default-web-app/web-inf/lib/org/apache/cocoon/processor/xsp/library/java/request.xsl processor.xsp.logicsheet.response.java = file://localhost/orion/default-web-app/web-inf/lib/org/apache/cocoon/processor/xsp/library/java/response.xsl processor.xsp.logicsheet.session.java = file://localhost/orion/default-web-app/web-inf/lib/org/apache/cocoon/processor/xsp/library/java/session.xsl processor.xsp.logicsheet.sql.java = file://localhost/orion/default-web-app/web-inf/lib/org/apache/cocoon/processor/xsp/library/sql/sql.xsl processor.xsp.logicsheet.esql.java = file://localhost/orion/default-web-app/web-inf/lib/org/apache/cocoon/processor/xsp/library/sql/esql.xsl processor.xsp.logicsheet.fp.java = file://localhost/orion/default-web-app/web-inf/lib/org/apache/cocoon/processor/xsp/library/fp/fp.xsl A strange solution but it works! /Theis.
