Summary: 0001429: amber: generating duplicate fields
Description: (rep by Bryan May)

We've been using Resin 2.1.x for ages now and I thought I would try to bite the bullet and upgrade to Resin 3. Things have been moving swimmingly until I ran into the big stack trace below.

The only configuration file that I have changed so far is web.xml to use the <database> element and the <ejb-server> element.

I have made no modifications to the EJB deployment descriptor.

It seems that Amber is creating two member variables with the same name. Has anybody run into this before?

Thanks in advance,

       Bryan

I believe that I found the cause.

My deployment descriptor had these two fields that pointed to the same column.

  <entity>
    <ejb-name>Foo_BarEJB</ejb-name>
    <local-home>test.BarHome </local-home>
    <local>test.Bar</local>
    <ejb-class>test.BarBean</ejb-class>

    <prim-key-class>int</prim-key-class>
    <primkey-field>foundInId</primkey-field>

    <persistence-type>Container</persistence-type>
    <reentrant>False</reentrant>

    <abstract-schema-name>Bar</abstract-schema-name>
    <sql-table>BAR</sql-table>

    <cmp-field><field-name>clusterFoundOnId</field-name><sql-column>found_in_id</sql-column></cmp-field>
    ...
</entity>

Commenting out the second definition, and replacing it with an implementation in the BarBean class has allowed the class to compile.

Rob sent me down the path that led to this.

Duplicate fields by the user.
