Hi,
Today, only a certification like SCJP doesn't make you a so different profile, because many people has it.
Try searching what the companies are looking for, and study the topics they ask.
For instance, I got this from a job offered:
Skills:
* Experience performing object oriented development
* Experience with J2EE architecture, including experience with one or more of the following: EJBs, Struts, Servlets, JMS, JNDI, J2EE Connectors, JDBC, Hibernate, ANT, etc
* Experienced with Java tools including WSAD, RAD, JBuilder, Eclipse, NetBeans preferred
* Knowledge of J2EE testing tools (i.e JUNIT, JTEST, Mock Objects, LoadRunner, etc) preferred
* Experience with IBM Websphere Application Server, ClearCase, Unix, and Oracle preferred
* UML design tools including Rational Rose/Enterprise Architect preferred
* Experience building scalable, mission critical applications
* Experience with full project life cycle from establishing requirements through delivery and production
* Experience managing onshore/offshore applications development services is a plus
Then do a lot of courses (or study from Internet), because IT is always changing, all the time.
