Hi: all, I am writing a plugin to integrate knime work flow with Jena (http://jena.sourceforge.net/) by adding a new database node JenaDatbasereader. In order to do that, I have to write a new DbReaderConnection class because Jena has it's own way of creating a connection to the database and then querying the data. when I try to instantiate the new DbReaderConnection class which I called JenaDbReaderConnection from the DBReaderNodeModel class (which I called JenaDBReaderNodeModel), I am having a class not found exception from the class loader. I wonder why is that? Does Knime uses it's own class loader to load the class and is there any security check or some thing that causes the class loader not to load the new JenaDatabaseReaderConnection class. Can some one shed some light on this issue.
Thanks in advance.
