This is really a great topic of discussion and there may be many answers depending of personal choices.
As
Java is very wide spread to cover the technology needs for variety of domains and Sun has done great job to divide it into 3 major categories.
Standard, enterprise and Micro.
I believe when one put himself/herself into IT market as an expert in particular domain with master level knowledge of a highly coupled bundle of 2-3 technologies and awareness of related technologies it satisfies the employer�s hunt for techie in desired areas. Remember once you put a bigger number in experience section, the person interviewing you expect more than just API's or syntax like the solution approach, design and other work mentioned in your resume.
