Constructor Detail

WebRowSetImpl

public WebRowSetImpl()
              throws java.sql.SQLException

Constructs a new WebRowSet object initialized with the default values for a CachedRowSet object instance. This provides the RIOptimistic provider to deliver synchronization capabilities to relational datastores and a default WebRowSetXmlReader object and a default WebRowSetXmlWriter object to enable XML output capabilities.

Throws:

java.sql.SQLException - if an error occurs in configuring the default synchronization providers for relational and XML providers.

WebRowSetImpl

public WebRowSetImpl(java.util.Hashtable env)
              throws java.sql.SQLException

Constructs a new WebRowSet object initialized with the the synchronization SPI provider properties as specified in the Hashtable. If this hashtable is empty or is null the default constructor is invoked.

Throws:

java.sql.SQLException - if an error occurs in configuring the specified synchronization providers for the relational and XML providers; or if the Hashtanle is null
