If you consider yourself simply a "Java developer" then it would be in your best interest not to apply-to/join-a company that is insistent on pigeonholing the developers into certain technologies. Avoid recruiters since all they do is keyword matching between a job requirement and a resume. Why were you not comfortable with a regular/back-end Java coding interview? What would you have preferred to be asked?

Are there any meetups in your city? Start networking. If your a good developers, then there is no need to just join any company for a paycheck. Join the right company.

The key question I ask anyone I interview is "how do you keep current"? Not everyone needs to spend their free time on some open-source project, but a proactive interest in your profession is a requirement IMHO. Get a free account on AWS and/or Google App Engine. Just create something.

Your skills have stagnated over the years. Do not get into this scenario again.
