So...should the following code work? I keep getting null pointers
whenever I try to set the descriptors myself (regardless of whether I
use the commented or uncommented version below):
---code---
//final JdbcConnectionDescriptor descriptor =
MetadataManager.getInstance().readConnectionRepository(
// getClass().getResourceAsStream("/connections.xml")
//).getDescriptor(new PBKey("$ALIAS$"));
final JdbcConnectionDescriptor descriptor = new
JdbcConnectionDescriptor();
logDescriptor(descriptor);
descriptor.setDefaultConnection(false);
descriptor.setJcdAlias(DBKEY.getAlias());
descriptor.setDbms(configuration.getDBConnect().getPlatform());
descriptor.setJdbcLevel(getJDBCLevel());
descriptor.setDriver(configuration.getDBConnect().getDriver());
descriptor.setProtocol(configuration.getDBConnect().getProtocol());
descriptor.setSubProtocol(configuration.getDBConnect().getSubprotocol());
descriptor.setDbAlias(configuration.getDBConnect().getDbalias());
descriptor.setUserName(configuration.getDBConnect().getUsername());
descriptor.setPassWord(configuration.getDBConnect().getPassword());
MetadataManager.getInstance().connectionRepository().addDescriptor(descriptor);
logDescriptor(descriptor);
PersistenceConfigurationDescriptor newPCD = new
PersistenceConfigurationDescriptor(
DBKEY,
MetadataManager.getInstance().readDescriptorRepository(getClass().getResourceAsStream("/model.xml")),
descriptor
);
MetadataManager.getInstance().addPersistenceConfiguration(newPCD);
---error---
null
java.lang.NullPointerException
