NoClassDefFound Exception
Hi,
The following piece of code creates a relational db from an XML file.
String nameoffile= "xmltodb.xml";
Database targetModel = new DatabaseIO().read(nameoffile);
BasicDataSource dataSource = new BasicDataSource();
dataSource.setUrl("jdbc:derby://localhost:1527/testonm10");
dataSource.setDriverClassName("org.apache.derby.jdbc.ClientDriver");
boolean alterDb = false;
Platform platform = PlatformFactory.createNewPlatformInstance
(dataSource);
if (alterDb) {
platform.alterTables(targetModel, false);
} else {
platform.createTables(targetModel, true, false);
}
I get the following exception:
java.lang.NoClassDefFoundError:

Looks like you're missing a library, commons-betwixt to be precise.
You can find it in the lib directory within the binary or source
distribution.
