Configuring Spring/JPA Hibernate on Eclipse

Question

I have been fighting for days to install Spring 3.1(latest) and Hibernate JPA on my system. I went through all the tutorial but have not been able to fix it. I've already installed Spring from Eclipse's Install New Software. I now want to add Hibernate JPA to it and want to test everything.

It doesn't matter which IDE you use. This is my spring-dao.xml:

Answer 2

I had the same problems. I spent a lot of time to install as STS as Spring on Eclipse on Windows as with tc server as with Tomcat . It didn't work something. I went to Ubuntu 10.04 LTS and now I don't have problem as with STS as with Eclipse with Spring as with Tomcat

Answer 3

If you have the option of choosing an IDE then I would recommend looking at Spring Tool Suite (STS). STS comes preinstalled with Spring stuff.

You may also check out Spring Roo. Spring Roo gives you a jumpstart and helps with the creation of all the scaffolding that you need for the projects that are based on Spring and hibernate.

Hope that helps.
