In eclipse JPA Entities from Tables it's convert column byte from mysql to byte in java.

How can i change to boolean (Netbeans can generate correctly)?

Thanks in advance for answer.

Answer 1

[Hmmmm. I don't see that the MySQL documentation says it has a data type of BYTE. Maybe you are mean BIT?]

Either way:

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, for MySQL, the data type BIT (along with BOOL and BOOLEAN) is mapped to the Java type byte in the file /runtime/vendors/MySql_5.1/MySql_5.1.xmi in the plug-in jar ./plugins/org.eclipse.datatools.enablement.mysql.dbdefinition_1.0.4.v201109022331.

You can extract the appropriate .xmi file, edit it, and return it to its jar and this should alter how entities are generated.
