trouble in running a transformation from the repository

[eric-code]

when i invoke the method (runTransformationFromRepository) in the class org.pentaho.di.sdk.samples.embedding.RunningTransformations with the code below

     instance.runTransformationFromRepository("MyRepoCE", "/home/admin", "parametrized_transformation", "admin", "password");

i got a exception like this:

org.pentaho.di.core.exception.KettleException: 
Cannot find repository "MyRepoCE". Please make sure it is defined in your /Users/tony/.kettle/repositories.xml file

	at org.pentaho.di.sdk.samples.embedding.RunningTransformations.runTransformationFromRepository(RunningTransformations.java:210)
	at org.pentaho.di.sdk.samples.embedding.RunningTransformations.main(RunningTransformations.java:90)

here is the content of my repository file

<?xml version="1.0" encoding="UTF-8"?>
<repositories>
  <repository>    
    <id>PentahoEnterpriseRepository</id>
    <name>MyRepoCE</name>
