Anybody used these frameworks in developing enterprise level applications here? have read so much about these two technologies but have not heard of anybody using it or saying anything about those cool stuffs on nairaland. Does it mean we don't do enterprise application development here? or is it that u guys use another set of tools?. sha, i intend using them in a generic hotel management system next yr

I use these at my current contract and have also used them at other gigs. I am not based in Naija though. I am really not sure what those that develop enterprise level apps in Naija use.

i use both frameworks

am using spring jdbc in place of normal jdbc,it helps eliminate alot of boilerplate code.

2 me i will say that spring and hibernate are one of the best things that have happened to JEE, i cant remember when last i open a connection, got a statement object.

It simply means you've not had to handle bulk data transfers and manipulation, or you are using the wrong frameworks.

there are other approaches now.

Spring hibernate is fast becoming old technology

@candylips
pls which other options do we have currently?

I use spring and hibernate ...
hibernate because i refuse to use jpa ( too old for annotations )
spring because they've thought of everything and it manages object lifecycle better than i'd do it myself : so better memory footprint
many hooks to numerous frameworks etc.

Hibernate almost always becomes a pain when you try to access complex table structures or persist complex object graphs.

I find myself resulting to jdbc for these cases.

I will stick with raw jdbc or use Ibatis

@Candylips
JDBC again? not me. Really av been trying to do a bidirectional one to many relationship, is so Confusing using Hibernate, its not just giving me what i want, av tried using a join tables but when i save the entities the join table don't reflect it.av been trying to map Students and PhoneNumber. A student can have like zero or more phones u know, i can do it with representing the students id on the PhoneNumber table as a foreign key but that will lead me to HQL queries which m trying to avoid. Since am using an ORM tool i still believe that its possible to implement it elegantly cos an ORM tool should automate those tasks. may be i will check out ibatis, hope is fully complaint with JPA?

Although you can use a join table it is not necessary

To get a bi-directional relationship one side has to own the relationship while the other references it

The owner of the relationship will be the M-1 side which is Phone so in the Phone object

@ManyToOne
@JoinColumn (name="Phone_id" )
private Phone phone;


so the 1-M side On the Student object will be like this

@OneToMany (mappedBy="phone" )
private Set phoneNumbers = new HashSet();


Get you hands dirty on Ibatis. It is better,faster and more flexible than Hibernate IMHO

@candylips
well done for ur important contribution, my manager insist on we using hibernate for the project, anyway when am done with the project i will take my time and study ibatis wella. lyk for how long av u been using enterprise java? it seem u have much experience from your posts
