Cause:
Cause:
=======
The J2SE 1.4 platform included the "Crimson" reference implementation for JAXP 1.1. The J2SE 5 platform includes a reference implementation for JAXP 1.3 based on the Apache "Xerces" library. IM 5.0.2 with JRE 1.5 requires specifying Xerces library since it use defaults to Crimson libraries for XML processing.

TIBCO IntegrationManager Editor 5.0.2 using Java Runtime Environment (JRE) 1.5 throws the error: java.io.IOException: Error reading schema: Provider org.apache.crimson.jaxp.SAXParserFactoryImpl not found.

Resolution:
=======

1). Stop the IM editor/Engine.

2). Edit the imed.tra/imse.tra files located at <tibco-home>/im/5.0/bin directory. You also need to make change in imse.tra to avoid getting any exceptions at runtime.

3). Set the following properties in both imed.tra/imse.tra

java.property.javax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl

java.property.javax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl

4). Restart IM editor/engines.
