log4j Error

When calling a sequence I get the following error:

log4j:ERROR No appenders could be found for category (SAXParser).
log4j:ERROR Please initialize the log4j system properly.
Server returned HTTP response code: 400 for URL: http://localhost:8080/orchestra
tor/OrchestratorGateway?xbd.sequence.uri=http://localhost:8080/orchestrator/Sequ
ences/UpdateSequence.xml

Any indea on why this error is occuring?

This are two errors. First the logging tool log4j complains that no properties file has been found. Thus it cannot initialize. This is not really a problem, but more a warning.

Second is the HTTP response from the server.

What are you doing? Using Java Tamino API? Look for a file log4j.properties. If it is in your classpath, everything is fine.

To be sure I will attach such a file.

Thanks, after adding the log4j.properties to my classpath. The log4j error disappeared. However, I am still getting the follwing error
Server returned HTTP response code: 400 for URL: http://localhost:8080/orchestra
tor/OrchestratorGateway?xbd.sequence.uri=http://localhost:8080/orchestrator/Sequ
ences/UpdateSequence.xml

And I am also getting this error

Please find attached the servlet file as well as the sequence where I am simply trying to update an entry in my tamino database.

And here is the servlet.
