Hi,
You are eligible to take the Architect Exam ( OCMJEA ). Having said that, you should make sure is the Architecture the path you want to take. This exam is different to Web Component / Java Programmer exam. I am sure you are aware that it is a 3 part exam. Also it is mandatory nowadays that you should attend Oracle training's to get your Architect Certification. The training could cost considerably, and it is based on the country you want to take the exam. Please check with Oracle site for the appropriate pricing. Good luck with your OCMJEA journey.
