Ive been using another JDO implementation and would like to use JPOX. What do i do ?
The only real changes you need to make are to any Meta-Data files. The MetaData file contains two types. The first type is generic (standard) JDO MetaData defined by the JDO specification. This is common across all JDO implementations and this will not need changing. The second type is vendor-specific and by definition will be specific to the JDO implementation being used. The vendor-specific MetaData is contained within the XML tag extension, specifying the vendor-name attribute that it applies to. If you want your code to run in several JDO implementations you can include several extension tags some for JPOX and some for your other JDO implementations. This results in your application being more portable – though clearly the most portable will be MetaData that contains no vendor extension tags.
