Are there no option to generate tables from entities in IntelliJ? Using JPA and eclipselink as implementation. Trying to generate tables for MySQL. All I see is options for importing.
Do I have to use Eclipse to generate tables?
I believe it is not possible in IntelliJ. As far as I remember from a project 1.5 years ago, we didn't use any exporting to database, everything was done automatically upon deploy to JBoss.
Hope this helps.

I was trying to use reverse engineering in hibernate in the latest Eclipse IDE but all the resources I came across seem to be outdated.
would appreciate it if I get some input as to how to go about this procedure.
I tried the steps in this link (https://www.codejava.net/frameworks/hibernate/java-hibernate-reverse-engineering-tutorial-with-eclipse-and-mysql )but was not able to generate the Entity classes with the annotations. This method generated a POJO with no annotations at all.
Would be thankful if I find a way to solve this problem.
You have to tick this check box in order to generate EJB3 annotations
I am using Spring Tool Suite (STS). I am confused is there any way to autogenerate POJO based on table in postgres sql along with mapping.
I know how to generate POJO from database table in Advanced Java project on eclipse but I tried for spring project in STS with no positive result.
In advanced Java project I simply use this link http://www.eclipse.org/webtools/dali/docs/3.2/user_guide/tasks006.htm
It would be helpful if anyone share their thoughts.
I've restricted access to the eclipse market place and a network with terrible connectivity issues , therefore i wont be able to download Jboss tools which is like more than 300MB .
Is there a way to generate jpa/hibernate model classes from database without using JBoss hibernate tools ?
yes, it is possible to generate hibernate/jpa specific model classes from you database using hibernate maven plugin. Only thing is your project should be maven project.

How to configure maven hbm2hbmxml and hbm2java to run one after the other in mvn clean install
Im a bit confused about this :
I've setuped a simple maven-archetype-webapp
So far i've been creating entities from a plain POJO, adding annotations as needed
But lately i think that there could be ways to ease this entity creations, so i googled
And found out about eclipse that could help me generate the JPA entities ..
I tried right clicking on my package that contains the entities, and new -> JPA -> Entity, only to find out that i can only make use of this in a JPA project.
In one hand, i have a maven project (which is not a JPA project created by eclipse), and in the other hand, i'd like to give eclipse JPA a try.
And one more thing, i have something in mind that we could design with a GUI tool, creating entities, defining the relations, defining configurations like the id generation sequence, multiple unique columns, compound key, etc and have the JPA entities generated for you.
Does this kind of tool exist ? Perhaps as an eclipse plugin or something else ?
JPA tooling can be added to an existing Eclipse project in a couple of ways, depending on the type of project you are starting with. If you have a Java project, you can right-click on it and use the "Configure" -> "Convert to JPA project..." menu item to add JPA project capabilities to an existing Java project. If you have a Web project or other WTP based project (known as "faceted" projects), you can simply add the JPA facet to the project in the project properties on the "Facets" node. If you are starting from scratch you can create a JPA project, which is basically just a Java project with JPA tooling added in.
I'm not sure if you are using m2e, but this is the Eclipse Maven integration tooling. There are some known issues using Maven with the JPA tooling in Eclipse, but there are workarounds that may work for you.
As for graphical diagramming tools for developing entities, this is coming to the Eclipse Dali Java Persistence Tools project for the next release - 3.0 (Indigo). You can try this functionality out now by downloading the JPA Diagram Editor. Check out the youtube video (search JPA Diagram Editor) for a quick demo of the functionality.
Sorry for the lack of links, but I can only post 1 per reply as a new user.
I'm learning hibernate and I am running into some issues. I'm reading "Harnessing Hibernate" by O'Reilly. They explain everything using ANT, but since I want to avoid writing a huge build.xml file, I'm trying to get it to work with IntelliJ.
I managed to make a mapping according to a DB table in a MySQL database, and wrote the bean for it. It worked, but I can't find any information on how to generate beans and SQL code, or how to reverse engineer with IntelliJ. I found loads of tutorials about Eclipse, using JBOSS Hibernate tools plugin, and the site claims this support for generating code is already in the standard installation of IntelliJ.
Am I forgetting some configuration such as adding libraries? I'm trying to find this out but I'm desperate now. Please don't suggest me to use Eclipse, I need IntelliJ for my current role.
AFAIK, IntelliJ IDEA includes the complete JPA/Hibernate support in its Ultimate Edition:
Generating Persistence Mappings from Database Schema
IntelliJ IDEA allows you to quickly
generate persistence mappings from any
database schema: Generating
Persistance Mappings
(source: jetbrains.com)
Now, the question is, what edition of Intellij IDEA are you using?
If you add the hbm2ddl to your Hibernate config and ask it to create the database schema you'll get it by running a single test or some other code that exercises Hibernate. Once you have it, turn off create.
Let Hibernate do the work.
