I am working with ojb rc5.
This is my situation:
I created the persistent java classes and the repository files, I configured
the conection for MSSql Server database; then I ran a simple unit test that expected a single AtributoImpl object, but it returned an error.
I was searching the mail archive for similar questions but I didn�t find anything.
All I know is that the connection is Ok and the repository and properties files are in the classpath.
Any help will be appreciated. Thanks in advance.
This is the repository_user.xml entry for the table I wanted to read:
<class-descriptor class="com.ecip.ojb.AtributoImpl" table="ec_atributo">
<field-descriptor autoincrement="true" primarykey="true" column="id_atributo" jdbc-type="INTEGER" name="idAtributo"/>
<field-descriptor column="atributo" jdbc-type="VARCHAR" name="atributo"/>
<field-descriptor column="descripcion" jdbc-type="VARCHAR" name="descripcion"/>
</class-descriptor>
This is the error I am getting:
