Though I prefer Toad or Oracle SQL Developer tool to connect Oracle database, sometimes it's useful to take away connect Eclipse to Oracle using JDBC using its Data Source Explorer view. This way y'all tin persuasion 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 as well as Eclipse or Oracle SQL Developer as well as Eclipse. Eclipse also allows y'all to persuasion Execution invention inwards both text as well as Graphical mode, which y'all tin purpose to troubleshoot functioning of your SQL queries. In this article, I'll tell y'all 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, equally y'all simply demand to driblet a JAR file inwards the classpath, nosotros volition endure using JDBC sparse driver to connect Oracle from Eclipse. Depending upon your Oracle version e.g. Oracle 10g or Oracle 11g y'all demand to download Oracle JDBC sparse driver e.g. ojdbc14.jar file. Just download this JAR file as well as configure it on Eclipse IDE. Enter username, password, as well as sid as well as y'all are laid upwards to execute SQL interrogation to Oracle database from Eclipse.
In lodge to connect to Oracle database instance, y'all demand ii things:
1) Eclipse IDE for Java EE developers, because that contains the database evolution plugin which doesn't come upwards along amongst 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 whatsoever type of JDBC driver, but I prefer Oracle JDBC sparse driver e.g. ojdbc14.jar file to connect to Oracle 11g instance. If y'all don't have, y'all tin download from here.
Once y'all receive got these ii things, nosotros are laid upwards to connect to whatsoever local or remote Oracle database event 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 event from Eclipse:
Tips similar this salvage a lot of fourth dimension as well as amend productivity as well as that's why I receive got ever said that goodness agreement of Eclipse IDE is must to expire an adept Java J2EE developer as well as developer should pass to a greater extent than or less fourth dimension to larn their tools e.g. Eclipse.
If y'all are primarily a Java EE developer as well as hence y'all tin also accept a await at Ram Kulkarni's Java EE Development amongst Eclipse book, which volition assist y'all to write code, debug, test, as well as troubleshoot Java EE vii applications right from the Eclipse IDE.
Now, let's run into each stride inwards petty fleck especial amongst screenshot if y'all are laid upwards to connect to Oracle database from Eclipse, follow it along:
Step 1: Open Eclipse IDE as well as Select Database Perspective
In lodge to opened upwards the Database Development perspective expire to Windows >> Open Perspective >> Other >> Database Development, equally 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 as well as choose "New Connection". This volition opened upwards the New Connection Profile window equally shown below. Now type Oracle as well as give your connectedness profile a meaningful name e.g. combination of application, host, as well as instance.
Step 3: Choose JDBC Driver as well as specify its location
Once y'all receive got selected the database, it's fourth dimension to choose the JDBC driver. To configure JDBC driver, simply click the setting icon on the previous covert equally 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, as well as JDBC sparse driver or other drivers. I receive got chosen the Oracle Thin Driver to connect Oracle 11g equally seen below:
Once y'all choose a especial driver, y'all tin run into the mistake message look at the top proverb "Unable to locate JAR/ZIP inwards the file organisation equally specified past times the driver definition: ojdbc14.jar", this way y'all demand to locate the path of this JAR inwards your local file system, equally shown below. If y'all don't specify the right JAR, y'all volition acquire "java.lang.classnotfoundexception oracle.jdbc.driver.oracledriver" error.
Once y'all are done, click Ok as well as and hence it volition accept y'all 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, as well as password required to connect to an Oracle database instance.
Step 5: Test Connection
Once y'all are done amongst putting connect detail, simply click the "Test Connection" button, if everything is goodness as well as hence y'all volition run into a ping succeed message, if non as well as hence y'all volition run into a "ping failed" message.
That's all well-nigh how to connect Eclipse to Oracle database using Java as well as JDBC. This is an immensely helpful tip if your application is using Oracle database at the backend as well as y'all oft demand to select, update or delete data.

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