The Oracle Java EE 6 Java Persistence API Developer Certified Expert Exam: Your Questions, Answered
You need 61% to pass the 1Z0-898 exam, and registration costs USD 245 (may vary by country). Since each attempt carries the fee, candidates who practice thoroughly first — on paper, on screen, under time pressure — put their money behind preparation rather than retakes.
The 1Z0-898 exam is the official test for the Oracle Java EE 6 Java Persistence API Developer Certified Expert certification from Oracle. For graduates and job seekers facing drastic competition, it does something a resume line cannot: it verifies your skills against a recognized standard, so when you enter an interview process, the credential helps you stand out on evidence rather than adjectives.
The official outline divides the 1Z0-898 exam into weighted domains, including:
- Advanced Java Persistence API Concepts ()
- Entity Inheritance and Object Relational Mapping ()
- Implementing Transactions and Locking ()
Print the Oracle Java EE 6 Java Persistence API Developer Certified Expert PDF from ExamPrepAway and mark these domains' key points directly on paper — annotating the difficult parts is a proven way to make them stick.
Recommended: Java programming experience, Java EE development experience, and knowledge of Enterprise JavaBeans technology. Oracle or Sun Certified Java Programmer certification is recommended.

Reviewing with your own annotations is efficient, and the tactile process keeps you motivated to continue. Many candidates find that once they start, learning this way becomes a genuinely happy process.
