Method Detail

configure

public void configure(org.apache.ojb.broker.util.configuration.Configuration pConfig)
               throws org.apache.ojb.broker.util.configuration.ConfigurationException

Description copied from interface: org.apache.ojb.broker.util.configuration.Configurable

configure an object using the Configuration pConfig

Specified by:

configure in interface org.apache.ojb.broker.util.configuration.Configurable

Parameters:

pConfig - the Configuration object used to configure current instance

Throws:

org.apache.ojb.broker.util.configuration.ConfigurationException

writeToFile

public void writeToFile(DescriptorRepository repository,
               ConnectionRepository conRepository,
               java.io.OutputStream out)

Write the DescriptorRepository to the given output object.

readDescriptorRepository

public DescriptorRepository readDescriptorRepository(java.lang.String filename)
                                              throws java.net.MalformedURLException,
                                                     javax.xml.parsers.ParserConfigurationException,
                                                     org.xml.sax.SAXException,
                                                     java.io.IOException

Read the repository configuration file.
If configuration property useSerializedRepository is true all subsequent calls read a serialized version of the repository. The directory where the serialized repository is stored can be specified with the serializedRepositoryPath entry in OJB.properties. Once a serialized repository is found changes to repository.xml will be ignored. To force consideration of these changes the serialized repository must be deleted manually.

Throws:

java.net.MalformedURLException

javax.xml.parsers.ParserConfigurationException

org.xml.sax.SAXException

java.io.IOException

readDescriptorRepository
