Following part discloses how to download and introduce Apache Derby.
Downloading Apache Derby
Visit the landing page of Apache Derby landing page https://db.apache.org/derby/. Snap the Download tab.
Select and click on the connection of the most recent form of Apache Derby.
On tapping the chose connect, you will be diverted to the Distributions page of apache derby. In the event that you see here, derby gives appropriations specifically, db-derby-canister, db-derbylib.zip, db-derby-lib-debug.zip, and db-derby-src.zip.
Download the db-derby-container organizer. Duplicate its substance to a different organizer where you needed to introduce Apache Derby. (for instance, say C:\Derby)
Presently, to work with Derby,
- Ensure that you as of now have set the JAVA_HOME variable by passing the area of canister envelope of Java Installation organizer, and incorporate the JAVA_HOME/receptacle in the PATH variable.
- Establish another climate variable, DERBY_HOME with esteem C:\Derby.
- The container envelope of db-derby-receptacle disseminations (we transformed it as C:\Derby\bin) contains all the necessary container documents.
As examined, Apache Derby can be introduced/conveyed in two different ways as follows −
- Installed mode − In this, you need to get to the information base utilizing Embedded Derby JDBC driver. You can begin and stop derby through Java application. Both Database motor and your application will run on a similar JVM.
- Organization Server mode − In this mode, you can get to Derby in an ordinary clientserver design, where Derby is implanted in the worker framework. At that point, the customer machines running in various JVM's (that of the Server) will send solicitations to the worker, and the worker reacts to those solicitations.
The customer can be another JVM in a similar framework machine of the worker or a Java application from a far off framework.
Introducing Derby in Embedded Mode
To introduce Apache Derby in implanted mode, incorporate the container record derby.jar in your CLASSPATH.
Or then again, you can set the classpath for required container records by running the setEmbeddedCP order. Peruse the container registry of Apache Derby and run this record as demonstrated beneath −
C:\Users\MYUSER>cd %DERBY_HOME%/bin
C:\Derby\bin>setEmbeddedCP.bat
C:\Derby\bin>SET DERBY_HOME=C:\Derby
C:\Derby\bin>set
CLASSPATH=C:\Derby\lib\derby.jar;C:\Derby\lib\derbytools.jar;C:\Derby/lib/derby
optionaltools.jar;C:\Users\Tutorialspoint\Google
Drive\Office\Derby\derby_zip\New folder\db-derby-10.12.1.1-
bin\lib;C:\EXAMPLES_\Task\jars\*;C:\EXAMPLES\jars\mysql-connector-java-5.1.40-
bin.jar;C:\Users\Tutorialspoint\Google Drive\Office\37.Junit
Update\jars;C:\Program Files\Apache Software Foundation\Tomcat
8.5\lib\*;C:\Derby\lib\*;
Subsequent to setting up Apache Derby, to get to it, run Java programs utilizing the installed driver.
Verification
You can check the arrangement utilizing the ij apparatus as demonstrated underneath −
C:\Derby\bin>ij
ij version 10.14
ij> connect 'jdbc:derby:SampleDB;create=true';
ij>
Installing Derby in Network Server Mode
To introduce Apache Derby in organization worker mode, you need to incorporate derbynet.jar and derbytools.jar documents to the CLASSPATH.
Or on the other hand, you can set the class way for required container documents by running the setNetworkServerCP order. Peruse the receptacle catalog of Apache Derby and run this document as demonstrated underneath −
C:\Users\MYUSER>cd %DERBY_HOME%/bin
C:\Derby\bin>setNetworkServerCP.bat
C:\Derby\bin>SET DERBY_INSTALL=C:\Derby
C:\Derby\bin>set
CLASSPATH=C:\Derby\lib\derbynet.jar;C:\Derby\lib\derbytools.jar;C:\Derby/lib/de

Starting Derby in Server Mode
You can begin Network Server by running the order startNetworkServer. Peruse the container registry of Apache Derby and run this order as demonstrated beneath −
C:\Derby\bin>startNetworkServer
Fri Jan 04 11:20:30 IST 2019 : Security manager installed using the Basic
server security policy.
Fri Jan 04 11:20:30 IST 2019 : Apache Derby Network Server - 10.14.2.0 -
(1828579) started and ready to accept connections on port 1527
Or then again, you can begin the worker utilizing derbyrun.jar as demonstrated underneath −
C:\Users\MYUSER>cd %DERBY_HOME%/lib
C:\Derby\lib>java -jar derbyrun.jar server start
Fri Jan 04 11:27:20 IST 2019: Security manager installed using the Basic server
security policy.
Fri Jan 04 11:27:21 IST 2019: Apache Derby Network Server - 10.14.2.0 -
(1828579) started and ready to accept connections on port 1527
Network Client
In customer, add the container records derbyclient.jar and derbytools.jar to the CLASSPATH. Or on the other hand, run the setNetworkClientCP order as demonstrated underneath −
C:\Users\MYUSER>cd %DERBY_HOME%/bin
C:\Derby\bin>setNetworkClientCP
C:\Derby\bin>SET DERBY_HOME=C:\Derby
C:\Derby\bin>set
CLASSPATH=C:\Derby\lib\derbyclient.jar;C:\Derby\lib\derbytools.jar;C:\Derby/lib
/derbyoptionaltools.jar;C:\Derby\lib\derby.jar;C:\Derby\lib\derbytools.jar;C:\D

Update\jars;C:\Program Files\Apache Software Foundation\Tomcat
8.5\lib\*;C:\Derby\lib\*;
At that point from this customer, you can send solicitations to the worker.
Verification
You can confirm the arrangement utilizing the ij instrument as demonstrated underneath −
C:\Derby\bin>ij
ij version 10.14
ij> connect 'jdbc:derby://localhost:1527/SampleDB;create=true';
ij>
Apache Derby Eclipse Environment
While working with Eclipse, you need to set the form way for all the necessary container documents.
Stage 1: Create an undertaking and set form way
Open overshadowing and make an example project. Right snap on the task and select the alternative Build Path - > Configure Build Path as demonstrated beneath −
In the Java Build Path outline in the Libraries tab, click on Add External JARs.
Furthermore, select the necessary container documents in the lib organizer of the Derby establishment envelope and snap on Apply and Close.
