问题
When generating JPA Entities from tables with Eclipse (Juno 4.2 for Java EE Developers) it proposes Object as default mapping type for properties I set to be Text.
That is quite annoying as I would have to set them all to String manually.
Has someone encountered that kind of problem and knows what to do? Is this a bug? Eclipse Indigo does not behave like that.
This is the /runtime/vendors/MySql_5.1/MySql_5.1.xmi from org.eclipse.datatools.enablement.mysql.dbdefinition_1.0.4.v201109022331.jar: (But as according to this file Text should be mapped to String this must be the wrong file - but how to find out the right one?)

Dali (the part of Eclipse that generates JPA entities) uses DTP (another part of Eclipse) to determine the Java attribute type for a particular data type. These mappings are database platform-specific and are specified in .xmi files in various DTP plug-ins.
For example, in Juno, for PostgreSQL, the data type ABSTIME is mapped to the Java type java.lang.Object in the file
/runtime/vendors/postgresql/postgresql_8.x.xmi
in the plug-in jar
./plugins/org.eclipse.datatools.enablement.postgresql.dbdefinition_1.0.2.v201110070445.jar.
Depending on your database platform and what other plug-ins you have installed, these settings could have changed between Indigo and Juno. You can extract the appropriate .xmi file, edit it, and return it to its jar and this should alter how entities are generated.
