Subject [jira] Commented: (ODE-242) Usage of Xerces classes generates instability with regard to app servers
Date Thu, 14 Feb 2008 22:31:07 GMT

    [ https://issues.apache.org/jira/browse/ODE-242?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12569118#action_12569118

Paul R. Brown commented on ODE-242:
-----------------------------------

Once upon a time, we had to hard-wire the version of Xerces that we were using because some
bugs in versions that were out there (e.g., shipping with Tomcat) would cause problems with
schemas when loading WSDL (as Matthieu was saying).

More likely than not, any modern version of Xerces will work.

>             Project: ODE
>          Issue Type: Bug
>          Components: BPEL Runtime
>    Affects Versions: 1.2

> Application servers typically include a version of xerces in their system classpath that
may conflict with
> the version used by Ode.  Altering the class loading hierarchy of an App Server such
as weblogic is
> not supported.  This means that applications wishing to bundle or use Ode will have a
tough time
> supporting different versions of the app server.  Applications may need to support multiple
versions
> of application servers due to support policies.  Therefore using a technology like xerces
may inhibit
> the adoption of Ode greatly.  In my experience higher level APIs (JAXB, JAXP, etc) are
far more likely
> to work across multiple versions of servers.
> An example of this is trying to use the current 1.2 version of Ode sources with Weblogic
9.2.
