Method Detail

setupJndiConfiguration

public void setupJndiConfiguration()
                            throws com.webobjects.jdbcadaptor.JDBCAdaptorException

In servlet context, when not using JNDI to obtain the database channel, you will get annoying error messages like javax.naming.NameNotFoundException: Name "comp/env/jdbc" not found in context. Set the property er.extensions.ERXJDBCAdaptor.ignoreJNDIConfiguration to true in order to suppress this messages.

Overrides:

setupJndiConfiguration in class com.webobjects.jdbcadaptor.JDBCContext

Throws:

com.webobjects.jdbcadaptor.JDBCAdaptorException

rollbackTransaction

public void rollbackTransaction()

Re-implemented to fix: http://www.mail-archive.com/dspace-tech@lists.sourceforge.net/msg06063.html. We could also use the delegate, but where would be the fun in that?

Overrides:

rollbackTransaction in class com.webobjects.jdbcadaptor.JDBCContext
