Are you sure you're not just getting a warning message? Xerces will report one if it cannot locate [1] a schema document for an import after: 1) querying its local cache; then 2) querying the grammar pool if one was registered; then 3) querying the entity resolver if one was registered; then 4) dereferencing the schema location hint if one was provided. If no schema document is found after all these steps, it's *not* an error. > Presumably, the code is looking for the schemaLocation > attribute, not finding it and instead trying to find > 'null'.

This isn't a bug, but it certainly could be improved. If you want these imports to resolve you should register an entity resolver which locates a schema document based on the target namespace (and possibly other information provided in the XMLSchemaDescription). > Thanks, > > JBF > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] [1] http://www.w3.org/TR/xmlschema-1/#schema_reference Michael Glavassevich XML Parser Development IBM Toronto Lab E-mail: [EMAIL PROTECTED] E-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
