You must first "WRITE CODE" and lots of it...till your keyboard aches of it ;). Well the difference between your certifications and an occupation is the practice. Get dirty writing ton of code in open source frameworks apart from the JXXX specs. Spring, hibernate, ibatis,
struts, velocity, wicket, tomahawk, icefaces, jquery, proto-type, gwt, dojo, etc. can come in handy.
BTW, I'm not trying to promote any particular framework here...just letting you know a few options. Look at your requirements(case-study) and choose from among them. Also try visiting "apache" and contribute to the common's library or write code for an open source framework. You'll sure be on yur way to getting "deployment" ready real soon!
