Jboss:Hypersonic:Manual table creation:CreateException

[clive jordan]

Hi Guys,

I know this is a rather jboss/hypersonic question, but I am having problems with manual database table creation with Hypersonic and entity beans.

I have a simple entity bean. I can ask Jboss to automatically create a table when the bean is deployed by defining this in my jbosscmp-jdbc.xml file:

<jbosscmp-jdbc>
   <defaults>
      <datasource>java:/DefaultDS</datasource>
  <datasource-mapping>Hypersonic SQL</datasource-mapping>
      <create-table>true</create-table>
   </defaults>
   <enterprise-beans>
      <entity>
     <ejb-name>Entity1Bean</ejb-name>
 <table-name>PERSON</table-name>
 <cmp-field>
....

And then I run my client to create a bean, all works fine and the entity is created in the database (checked using DatabaseManager).

If I drop the table and create it using SQL (actually from ant) using the following sql code:

create text table person
( 
pid varchar not null primary key,
name varchar,
age integer
);
commit;

The 'text' is a Hypersonic-specific sql statement.

and change the jbosscmp-jdbc.xml entry:

....
<create-table>false</create-table>
....

Then redeploy the app, all seems fine until I run the client. When the client calls the create() method, I get this:

CreateException:Could not create entity:java.sql.SQLException: The table's data source for has not been defined in statement [INSERT INTO PERSON (pid, name, age) VALUES (?, ?, ?)]

I have examined the table schema created by the sql file compared to that generated by jboss and they seem identical.

Am I missing something here or do I need to configure something else ?

Any help would be appreciated!

Thanks,
Clive

Hi Guys,

I solved this problem so thought I'd round off in case anyone ever has the same issue.

In the hypersonic documentation, it states that you need to create a table with the text attribute in order to make it persistant and not a memory-only table:

[CODE}
create [B]text[/B] table person
(
pid varchar not null primary key,
name varchar,
age integer
);
[/CODE]

However, this seems to cause Jboss to not recognize the table. Removing the 'text' solved the problem. So either the documentation is incorrect (or I dont understand it) or Jboss does something under the covers to make the table permanent when accessing it.
