Though I prefer Toad or Oracle SQL Developer tool to connect Oracle database, sometimes it's useful to straight connect Eclipse to Oracle using JDBC using its Data Source Explorer view. This way you lot tin sentiment data, run SQL queries to the Oracle database right from your Eclipse window. This volition salvage a lot of fourth dimension wasted during switching betwixt Toad in addition to Eclipse or Oracle SQL Developer in addition to Eclipse. Eclipse also allows you lot to sentiment Execution excogitation inwards both text in addition to Graphical mode, which you lot tin purpose to troubleshoot functioning of your SQL queries. In this article, I'll tell you lot steps to connect Eclipse to Oracle database. Since Eclipse uses Java to connect to Oracle database, it asks for JDBC driver information. Since connecting using sparse Oracle JDBC driver is much easier, every bit you lot merely demand to drib a JAR file inwards the classpath, nosotros volition survive using JDBC sparse driver to connect Oracle from Eclipse. Depending upon your Oracle version e.g. Oracle 10g or Oracle 11g you lot demand to download Oracle JDBC sparse driver e.g. ojdbc14.jar file. Just download this JAR file in addition to configure it on Eclipse IDE. Enter the username, password, in addition to sid in addition to you lot are hit to execute SQL query to Oracle database from Eclipse.
In companionship to connect to Oracle database instance, you lot demand ii things:
1) Eclipse IDE for Java EE developers, because that contains the database evolution plugin which doesn't come upwards along alongside Eclipse IDE for Java developers. You tin download the latest version of Eclipse IDE for Java EE developers here.
2) Oracle JDBC JAR, since Eclipse uses JDBC to connect to Oracle database it needs JDBC driver JAR for Oracle. You tin purpose whatever type of JDBC driver, but I prefer Oracle JDBC sparse driver e.g. ojdbc14.jar file to connect to Oracle 11g instance. If you lot don't have, you lot tin download from here.
Once you lot receive got these ii things, nosotros are hit to connect to whatever local or remote Oracle database illustration from Eclipse IDE. I am using Eclipse Java EE IDE for Web Developers, Version: Kepler Service Release 2.
Here are the exact steps to connect Oracle illustration from Eclipse:
Tips similar this salvage a lot of fourth dimension in addition to amend productivity in addition to that's why I receive got e'er said that goodness agreement of Eclipse IDE is must to acquire an practiced Java J2EE developer in addition to developer should pass to a greater extent than or less fourth dimension to acquire their tools e.g. Eclipse.
If you lot are primarily a Java EE developer hence you lot tin also accept a expect at Ram Kulkarni's Java EE Development alongside Eclipse book, which volition assist you lot to write code, debug, test, in addition to troubleshoot Java EE vii applications right from the Eclipse IDE.
Now, let's encounter each pace inwards lilliputian chip special alongside screenshot if you lot are hit to connect to Oracle database from Eclipse, follow it along:
Step 1: Open Eclipse IDE in addition to Select Database Perspective
In companionship to opened upwards the Database Development perspective choke to Windows >> Open Perspective >> Other >> Database Development, every bit shown below:
Step 2: Create Connection Profile
For creating a novel connectedness profile, choose the "Database Connection" at the top left inwards the Database Development view, right click in addition to choose "New Connection". This volition opened upwards the New Connection Profile window every bit shown below. Now type Oracle in addition to give your connectedness profile a meaningful name e.g. combination of application, host, in addition to instance.
Step 3: Choose JDBC Driver in addition to specify its location
Once you lot receive got selected the database, it's fourth dimension to choose the JDBC driver. To configure JDBC driver, merely click the setting icon on the previous covert every bit shown below:
After that, the next covert volition opened upwards which volition listing downwards all JDBC drivers for supported Oracle versions e.g. Oracle 10g, Oracle 11g, in addition to JDBC sparse driver or other drivers. I receive got chosen the Oracle Thin Driver to connect Oracle 11g every bit seen below:
Once you lot choose a special driver, you lot tin encounter the fault message look at the top proverb "Unable to locate JAR/ZIP inwards the file organization every bit specified past times the driver definition: ojdbc14.jar", this way you lot demand to locate the path of this JAR inwards your local file system, every bit shown below. If you lot don't specify the right JAR, you lot volition acquire "java.lang.classnotfoundexception oracle.jdbc.driver.oracledriver" error.
Once you lot are done, click Ok in addition to hence it volition accept you lot to the previous screen. Click side past times side there.
Step 4: Specify Database Connection details
Now, it's fourth dimension to specify the database connectedness details e.g. host, port, sid, username, in addition to password required to connect to an Oracle database instance.
Step 5: Test Connection
Once you lot are done alongside putting connect detail, merely click the "Test Connection" button, if everything is goodness hence you lot volition encounter a ping succeed message, if non hence you lot volition encounter a "ping failed" message.
That's all most how to connect Eclipse to Oracle database using Java in addition to JDBC. This is an immensely helpful tip if your application is using Oracle database at the backend in addition to you lot oftentimes demand to select, update or delete data.

Steps to connect Oracle database from Eclipse
The steps are just similar to what I receive got shown you lot earlier piece connecting to Microsoft SQL Server from Eclipse IDE, here, the alone divergence is, this time, nosotros are choosing Oracle from the listing of database in addition to installing Oracle JDBC driver instead of SQL Server JDBC driver.Here are the exact steps to connect Oracle illustration from Eclipse:
- Open Eclipse IDE in addition to Select Database Perspective (Windows >> Open Perspective >> Other >> Database Development).
- Create Connection Profile, Chose Oracle
- Choose JDBC Driver in addition to specify its location
- Specify connectedness special e.g. host, port, username, in addition to password
- Test Connection
Tips similar this salvage a lot of fourth dimension in addition to amend productivity in addition to that's why I receive got e'er said that goodness agreement of Eclipse IDE is must to acquire an practiced Java J2EE developer in addition to developer should pass to a greater extent than or less fourth dimension to acquire their tools e.g. Eclipse.

Once you lot choose a special driver, you lot tin encounter the fault message look at the top proverb "Unable to locate JAR/ZIP inwards the file organization every bit specified past times the driver definition: ojdbc14.jar", this way you lot demand to locate the path of this JAR inwards your local file system, every bit shown below. If you lot don't specify the right JAR, you lot volition acquire "java.lang.classnotfoundexception oracle.jdbc.driver.oracledriver" error.
Once you lot are done, click Ok in addition to hence it volition accept you lot to the previous screen. Click side past times side there.
