Context:
I'm on Windows 10 using Netbeans IDE 8.1 .
I downloaded Hibernate OGM from sourceforge at this adress:
https://sourceforge.net/projects/hibernate/files/hibernate-ogm/5.3.1.Final/hibernate-ogm-5.3.1.Final-dist.zip/download
I then extracted all its files.
I found under hibernate-ogm-5.3.1.Final\dist\lib\mongodb the following files
I copied these files under my project's folder.
When I try to add a new driver in netbeans:
I get the message/error Driver Class is missing...
What am I doing wrong?
The MongoDB Java driver is not a JDBC driver. That's the reason you cannot add it to Netbeans as such. This plugin should do what you are looking for: http://plugins.netbeans.org/plugin/52638/nbmongo
I've never used it though because I prefer to connect using the MongoDB client.
The JDBC standard is for relational databases and, at the moment, there isn't an equivalent for NoSQL databases. For this reason, Hibernate OGM uses its own dialect to connect to the datastore. The dialect will then use, underneath, the required library for the chosen db.

I am trying to learn JDBC. The first step is to connect Oracle DB to eclipse. I installed Oracle XE. Now, when I am trying to connect to eclipse, I do not see a list of drivers.
Also, as according to this page, I cannot see Oracle Database Connection. I only see "Oracle"
I also tried opening the eclipse after cleaning (adding -clean in the .ini file) But it didn't work. What am I missing here?
You can download the JDBC driver from OTN and add it to the classpath.
I need to reverse engineer my database tables into Entity to run a Java EE project on JBoss AS 7. So I've added into the Services the JBoss application server and added as well as resources a MySQL datasource.
However, when I try to run the wizard Create Entity from Database I can see as only option the default ExampleDS Database. There is no other option to create a new DataSource or use the MySQL DataSource that I've installed on JBoss.
I wonder if it's a NetBeans bug, or I'm missing something. I'm using NetBeans 8.0.1 version.
I think it's an issue with the plugin that you are using for connecting to the application server. I remember I had this issue when I first tried to generate Entity classes from a Database using a Datasource on WildFly. Are you sure that the target application server is JBoss AS 7 and not WildFly ?
If so, try to connect the application to a JBoss AS 7 /EAP 6 instead and see if it works.
Hope it helps
Edit: I've included a JBoss NetBeans tutorial which shows the steps for reverse engineering database tables into Entity classes (and then JSF pages).
I have a Java project which uses Struts and Hibernate. I am using PostgreSQL as the database for the project.
I have imported the .jws file in JDeveloper. All the java and jsp files are imported to the project.
When I tried to run the project multiple errors came out. I think it's due to a database connection failure.
Do I need to configure pgsql with the project?
Thanks in advance.
You have to provide more info on what the errors are.
But some common problem in JDeveloper when using the bundled server to test is that (if you are using datasources) you have to place the driver jars in the server lib folder or declare it as a Library by going to Tools->Manage Libraries.
If you post what errors are you receiving and how are you connecting to the database we might be able to help you a little more.
You'll need to add the postgreSQL jdbc jar files to your project and to the embedded WebLogic instance.
Tell us the specific error you are getting and we'll help you more.
I am trying to crack out some simple examples with Eclipse Helios Java EE and Postgres 9.0. When I try to configure JPA data source with Postgres 9.0. The data source is created and the test connection works. But in the data source window , the tables under the 'public' schema never gets listed. I updated the datasource to use the latest Postgres 9.0 Jdbc type 4 drivers. Since the tables dont get listed , under JPA tools , the generate entities from tables wont work. What could be the problem ?
In connection properties set URL to one of this formats:
jdbc:postgresql:database
jdbc:postgresql://host/database
jdbc:postgresql://host:port/database
I'm starting to use Java EE developing on Eclipse IDE, using GlassFish and the default Java database. What I should do if I want to change the database to Oracle?
The application runs on Glassfish and Google App Engine. But is there a way from Eclipse to deploy it to my own server?
You should be able to deploy locally to Glassfish and Oracle using Eclipse. (It's easy to do with IntelliJ.)
All you have to do to use Oracle is add the JDBC driver JAR to the appropriate spot in your CLASSPATH, use the new driver .class, and change the connection URL.
The driver JAR should match your JDK (e.g., ojdbc6.jar) and database version. It should come with your database or you can download it here.
I don't know if the JAR should go in your WEB-INF/lib or a server /lib; consult your docs to be sure.
One more thing: it goes without saying that you'll have to set up Oracle (e.g., proper credentials), create the new schema, and add the tables and indexes before you run your Java app. I thought I'd spell it out to be safe.
