Hi,
I've experience with Java, Servlets, Jsps and also some knowlegde of Struts.
Now i have some free time and I wanted to learn a new tecnology that could be very helpful for a job in the future. I have no idea of EJBs nor Web Services. Which tecnology do you think it's more useful now in J2EE projects?. Or are both very important as I guess?
Thanks in advance
Jorge

At present, EJB has become more prevlent, it is not longer a addon skill but for now webservices it is nice to have skill, more over learning basics of webservice and implementing it is bit easier than EJB and number of J2EE projects using EJB is more than the ones with Webservices/soap, which means you can survive without knowing webservices. In theory I would give learning EJB's more priority than webservices. In reality, you'll never know ...

Both! These technologies are not exclusive of each other and can actually be used together in interesting ways. Without going to deep, lets just say that a developer can expose an EJB as a Web Service for B2B!

Yes, I will follow your advice and study both tecnologies. :-)
What's easy to understand, Web Services or EJBs?. I guess both need some time to get used to, but EJBs are very useful for implementing the model in a MVC framework and Web Services for exchanging data between applications.

I'd start with EJB because it's a building block for developing web services on top of J2EE.
