Re: Deploying Multiple beans from a single JAR

Sundari S Sat, 09 Feb 2002 00:47:51 -0800

Hi,

I think I have slightly missed in specifying explicitly in my questions that I was using Weblogic 5.1 version. Sorry about that.

But, anyway, I am just enclosing the site for weblogic5.1 dtd for rdbms xml file which says the following :

<!ELEMENT weblogic-rdbms-bean (
    pool-name,
    schema-name?,
    table-name,
    attribute-map,
    finder-list?,
    options?
)>

http://www.bea.com/servers/wls510/dtd/weblogic-rdbms-persistence.dtd

So, here, there is only one <weblogic-rdbms-bean> element (mani element) for ONE BEAN.

So, in this case, how do I work-around the problem of creating a single jar for all the rdbms accessing beans, in my JAR ??

Do let me know.

Thanks and Regards,

Sundari. S

See response inline...

I have a directory called META-INF that contains all 3 xml files.

Hope these help.

If you look in the DTD it indicates that there can be more than one
element: "weblogic-rdbms-bean+"
<!ELEMENT weblogic-rdbms-jar (
    weblogic-rdbms-bean+,
    weblogic-rdbms-relation*,
    create-default-dbms-tables?,
    validate-db-schema-with?
)>

<weblogic-rdbms-bean>
    <ejb-name>ejbOne</ejb-name>
    <data-source-name>ejbPoolDev</data-source-name>
    <table-name>tableOne</table-name>

<field-map><cmp-field>cola</cmp-field><dbms-column>ColA</dbms-column></field
-map>

<field-map><cmp-field>colb</cmp-field><dbms-column>ColB</dbms-column></field
-map>
     .....
</weblogic-rdbms-bean>

<weblogic-rdbms-bean>
    <ejb-name>ejbTwo</ejb-name>
    <data-source-name>ejbPoolDev</data-source-name>
      .....
</weblogic-rdbms-bean>
