I am creating web application with Grails web frame work. I have created the application and modify the DataSource.groovy file like this.

dataSource {
    pooled = true
    driverClassName = "cubrid.jdbc.driver.CUBRIDDriver"
    username = "dba"
    password = "123"
}

And my environment for the connection is development coded like this which connects my application to the CUBRID database.

environments {
    development {
        dataSource {
            dbCreate = "create" // one of 'create', 'create-drop', 'update', 'validate', ''
            url = "jdbc:cubrid://localhost:30000/grailsDB"
        }
    }
}

I tried several times with CUBRID bt its not work out. It populates the following error message.

Error creating bean with name 'transactionManagerPostProcessor': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager': Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Cannot resolve reference to bean 'hibernateProperties' while setting bean property 'hibernateProperties'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hibernateProperties': Cannot resolve reference to bean 'dialectDetector' while setting bean property 'properties' with key [hibernate.dialect]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dialectDetector': Invocation of init method failed; nested exception is org.springframework.jdbc.support.MetaDataAccess Exception: Error while extracting DatabaseMetaData; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot load JDBC driver class 'cubrid.jdbc.driver.CUBRIDDriver'.

 The driver is not supported (Cannot load JDBC driver class 'cubrid.jdbc.driver.CUBRIDDriver' Error message) but the application is coded in Groovy language. Its well supported with Java language. Please give a solution it would be a great help. Thank you.

Dhip.

CREATE FUNCTION "tblpacientesinsertar"("paciente" OBJECT) RETURN STRING
AS LANGUAGE JAVA
NAME 'TblPacientes.Insertar(cubrid.sql.CUBRIDOID) return java.lang.String'

I want to pass a custom object class, but I dont know if CUBRIDOID is the right type.

My custom type is public class BoPacientes.

My stored procedure is public static String Insertar(BoPacientes paciente).

C# code looks like:

public BoPacientes Insertar(BoPacientes objeto)
        {
            .....//code code

                       CUBRIDCommand com = new CUBRIDCommand();
                        com.Connection = con;
                        com.CommandText = "select tblpacientesinsertar(" + objeto + ")";
                        con.Open();

       .......//some code logical

       } 

The error I receive is:

Semantic: Dev9.DataAccess.Pacientes.BoPacientes is not defined.
select tblpacientesinsertar(Dev9.DataAccess.Pacientes.BoPacientes) 

I have a java object called BoPacientes.Class registered in CUBRID.

This can be visualised with the following query:

select class_name, attr_name, domain_class_name
from db_attribute
where data_type = 'OBJECT';


Which outputs (for instance):

 class_name

attr_name

 domain_class_name

 db_serial

 owner   

 db_user


So in principle, it can be said that db_serial.owner is of type db_user. This resembles what Oracle does with UDT's but it seems to be much more powerful, because tables and UDTs are the same in CUBRID. Especially the fact, that db_user attributes can be dereferenced from db_serial.owner (e.g. db_serial.owner.name) looks very similar to Oracle.

Now, my question is:

In Oracle JDBC, UDT's can be deserialised using java.sql.SQLData (which is extended by org.jooq.UDTRecord, for instance). Can this be done in CUBRID, as well? When I deserialise db_serial.owner, I get the CUBRIDOID object. But in fact, I might be interested in a complete deserialisation of that db_user, using SQLData.

Are there any tools that could be used to automatically generate Java/JDBC code working with CUBRID?

For exampe, something like:

http://platform.netbeans.org/tutorials/nbm-crud.html

Or any tool which I can use to generate the right CUBRID java code without having to learn all the jdbc driver "internals", so to say...
