Apache OpenJPA 1.1.0 Now Available

Posted in Java, OpenJPA, OpenSource by plunchete on June 26, 2008

Apache OpenJPA 1.1.0 is now available at and via Maven. Version 1.1.0 includes a number of new features and bugfixes, including:

  • Improvements in SQL generation for DB2, Oracle and MySQL
  • Support for memory-friendly streaming of BLOB and CLOB data
  • Support for interface-only domain models
  • Collections and Maps can now contain primitives, enums and @Embeddables, as well as @Entity and @MappedSuperclass types
  • Assorted performance and scalability improvements

For more details, see the release notes.

OpenJPA 1.1.0 was released some weeks ago but until yesterday we didn’t have a oficial announce, they has some problems with the artifacts signatures in maven.

The support for memory-friendly streaming of BLOB and CLOB data was my work in the summer of code 🙂

    Oh..thanks god I, at last, found you.

    I’d heard that @Persistent annotation can work for large lobs, for lob too large so that my physical memory can’t hold it all.
    But isn’t it a standard nor portable way? more question.

    I, actually, have a problem with mysql for not streaming blobs in jdbc level.
    the ’emulateLocators=true’ property seems work for only selection time.

    Does OpenJPA’s @Persistent annotation solves this problem?
