Hello, dear stuff!
I am newbie in EJB, here is my problem description
1. I use Xdoclet
2. Using ODBC I created datasource to MsAccess , and it works (tested!).
I want to work with table called "table1"
3. I Created CMP Ejb , Lookup returns the object, no any problem at this step
4. But findByPrimaryKey fails! My table isn't emty, it contains a couple of
lines.
The most strange is the error I got:
"Find failed: java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver]
The Microsoft Jet database engine cannot find the input table or query
'Person'.
Make sure it exists and that its name is spelled correctly."
If I rename my table1 to Person - it works!!!!
... and the question is how to map EJB to table????
Ejb jar contains line
<abstract-schema-name>table1</abstract-schema-name>
As I understood, this is the place where I refer my EJB to particular table.
Am I wrong?
I use eclipce plugin , so maybe it has some "bugs".... Hard to believe,
but possible?
My class starts as follows:
/**
* @ejb.bean name="Person"
* display-name="Name for Person"
* description="Description for Person"
* jndi-name="ejb/PersonBean"
* primkey-field = "numberFld"
* type="CMP"
* cmp-version="2.x"
* view-type="both"
* schema = "table1"
*
*
*/
public abstract class PersonBean implements EntityBean {
