Greetings!
I am trying to set up OJB in client/server mode.
I am using OJB 0.9.4 ODMG API with MS SQL Server.
The client and server are on the same machine.
I have a test case which works fine in single vm mode,
but when I switch to client/server, I get an error. More information below.
Has anyone experienced this problem? Any ideas on what is causing it and
how to fix it? The exception is thrown when I try to open the database.
=================================================================================
The Code which causes the Error
================================================================================
protected void setUp()
{
if ( dbName == null )
{
try
{
dbName = ((PersistenceBrokerConfiguration) PersistenceBrokerFactory
.getConfigurator()
.getConfigurationFor(null))
.getRepositoryFilename();
}
catch ( ConfigurationException e )
{
dbName = "repository.xml";
}
}
try
{
if ( odmg == null ) { odmg = OJB.getInstance(); }
if ( odmg != null && db == null )
{
db = odmg.newDatabase();
db.open(dbName, Database.OPEN_READ_WRITE); // <== Exception Thrown
Here
}
}
catch ( Throwable t )
{
LogService.logError("setUP ERROR: " + t.getMessage(),
OJBTest.class.getName(), t);
fail( "OJBTest::setUp ERROR: " + t.getMessage() );
}
}
