Weston,

When i don't add the jboss-common-jdbc-wrapper.jar in myapplication/lib directory, my application was successfly loaded.

But when i add it, the following error was shown :

java.lang.UnsupportedOperationException: Do not know how to handle method=public abstract long java.sql.Blob.length() throws java.sql.SQLException
	at org.jboss.resource.adapter.jdbc.remote.WrapperDataSourceService.invoke(WrapperDataSourceService.java:247)

and my code is :

final Blob blob = rs.getBlob(names[0]);
		return blob != null ? blob.getBytes(1, (int) blob.length()) : null;
