We are getting the following messages shortly after our App starts up when using MSSQL:

We traced it down to com.webobjects.jdbcadaptor.MicrosoftPlugIn that ships with WO, more specifically the jdbcInfo method which removes the type info for those types. Does anybody why?

The *identity ones are removed as they are not compatible with EOF. I am not sure about the others, perhaps not compatible with EOF or the Java types?

public NSDictionary jdbcInfo() {
boolean isLogging = NSLog.debugLoggingAllowedForLevelAndGroups(2, 0L);
NSMutableDictionary jdbcInfo = super.jdbcInfo().mutableClone();
NSMutableDictionary typeInfo = ((NSDictionary) jdbcInfo.objectForKey("typeInfo")).mutableClone();
typeInfo.removeObjectForKey("bigint identity");
typeInfo.removeObjectForKey("decimal() identity");
typeInfo.removeObjectForKey("int identity");
typeInfo.removeObjectForKey("numeric() identity");
typeInfo.removeObjectForKey("nchar");
typeInfo.removeObjectForKey("ntext");
typeInfo.removeObjectForKey("nvarchar");
typeInfo.removeObjectForKey("smallint identity");
typeInfo.removeObjectForKey("tinyint identity");
typeInfo.removeObjectForKey("sql_variant");
JDBCPlugIn._takeValueForKeyPath(typeInfo, "0", "money", "createParams");
JDBCPlugIn._takeValueForKeyPath(typeInfo, "0", "sysname", "createParams");
jdbcInfo.setObjectForKey(typeInfo, "typeInfo");
if (isLogging)
NSLog.debug.appendln((new StringBuilder("fetched MS SQL Server (")).append(databaseProductName()).append(") JDBC Info = ").append(jdbcInfo).toString());
return jdbcInfo;
}


Thanks,
