Oracle Java Enterprise Edition 5 Web Component Developer Certified Professional (1Z0-858) — Questions Candidates Actually Ask
The 1Z0-858 exam, officially known as Oracle Java Enterprise Edition 5 Web Component Developer Certified Professional, is the Oracle test that leads to the Java Technology certification at the Professional level. Passing it validates the skills employers expect from a certified professional. It is also associated with related credentials such as Oracle Certified Professional, Java EE Web Component Developer.
The 1Z0-858 exam contains 60 questions, and you have 120 minutes to complete them. Work out your per-question pace before test day, and flag slow items instead of stalling on them — time pressure, not knowledge, sinks many first attempts. Timed mock exams in the Actual4Exams test engines are the most reliable way to build that rhythm.
The passing score for the 1Z0-858 exam is 66%, and the official registration fee is USD 245 (may vary by region). If you miss the mark, a retake means paying the full fee again, so book your seat only when you are ready. A practical benchmark: score consistently above the passing line on timed practice tests before scheduling the real exam.
