- Java Development Kit (JDK)
- Apache Derby
Introduction
This tutorialrequires the Java Development Kit (JDK)and the Apache Derby software.
First, this section describes which JDK release is required, asks you to install it if you haven't already,then shows you how to configure and verify your installation.
Next, it shows you how to install the Apache Derby software,configure your environment to use the Derby Embedded JDBC driver,and verify your installation with the Derby sysinfo tool.
Java Development Kit (JDK)
Derby requires Java 2 Standard Edition (J2SE) 9 or higher.Only the Java Runtime Environment (JRE) is required to run Derby,but this tutorial compiles a Java application, so it requiresthe Java Development Kit (JDK).
If you already have a JDK installed, verify you are configured to use it,then proceedto the Apache Derby installation section.
Install JDK
If you have not already installed a JDK,download and install it now. No specific vendor implementation is required;the only requirement is that it be certified for J2SE 9 or higher.Java's reference implementation is athttp://www.oracle.com/technetwork/java/javase/downloads/index.html.After installing the JDK of your choice, proceed to the next section.
Configure JDK
Set the JAVA_HOME environment variable to the root location ofthe JDK installation directory.The examples below useC:jdk1.9 for Windows and /opt/jdk1.9 for UNIX, but be sure to use the actuallocation on your system. (e.g. The default installation location used by the JDK installer might be something like C:Program FilesJavajdk1.9.0_11-b21)
Windows:C:> set JAVA_HOME=C:jdk1.9
UNIX Korn Shell:$ export JAVA_HOME=/opt/jdk1.9
Next set the PATH environment variable to include the JDKbin directory.The PATH variable tells the operating system where to find thejava interpreter and the javac compiler.
Windows:C:> set PATH=%PATH%;%JAVA_HOME%bin
In Windows, these environment variables can also be set from - right click 'My Computer' -> Advanced -> Environment Variables.
UNIX Korn Shell:$ export PATH=$JAVA_HOME/bin:$PATH
Verify JDK
Use the java -version command, as shown below,to verify the installed release:
java -versionjava version '9'Java(TM) SE Runtime Environment (build 9+181)Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode)
The output you see may be different from what is shown above becausethe java -version command outputs vendor-specific information;however, if you don't see what looks like valid version information, then STOP!And don't proceed until you resolve that problem.
Apache Derby
Download Derby
Download the binary Apache Derby distribution from the Derby web site at http://db.apache.org/derby/derby_downloads.html.These tutorial instructions use version 10.15.2.0 and assume you downloaded one of the binary distribution files listed in the table below:
| Operating System | Download File |
|---|---|
| Windows | db-derby-10.15.2.0-bin.zip |
| UNIX, Linux, and Mac | db-derby-10.15.2.0-bin.tar.gz |
Install Catalina 10.15
If a more recent release is available, download that, then substitute that version number for 10.15.2.0 in the following instructions.
Install Derby
Choose the directory into which you want to install the Derby software. You must have write permissions to this directory. The sample instructions below use C:Apache for Windows and /opt/Apache for UNIX; be sure to use your actual location. Copy the software distribution to the location you choose, then extract it as shown below.
Windows (use your extraction tool e.g. WinZip -- these instructions use mks unzip):mkdir C:Apachecopy db-derby-10.15.2.0-bin.zip C:Apachecd C:Apacheunzip db-derby-10.15.2.0-bin.zip
UNIX:mkdir /opt/Apachecp db-derby-10.15.2.0-bin.tar.gz /opt/Apachecd /opt/Apachetar xzvf db-derby-10.15.2.0-bin.tar.gz
In both cases, the software will now be extracted into a subdirectory named db-derby-10.15.2.0-bin.
Set DERBY_INSTALL
Set the DERBY_INSTALL variable to the location where youinstalled Derby.Examples are shown below, but be sure to use the actual location on your system:
Windows:C:> set DERBY_INSTALL=C:Apachedb-derby-10.15.2.0-bin
UNIX Korn Shell:$ export DERBY_INSTALL=/opt/Apache/db-derby-10.15.2.0-bin
Configure Embedded Derby
To use Derby in its embedded mode set your CLASSPATH to include the jar files listed below:
- derby.jar: contains the Derby engine and the Derby Embedded JDBC driver
- derbytools.jar: optional, provides the ij tool that is used by a couple of sections in this tutorial
You can set your CLASSPATH explicitly with the command shown below:
Windows:C:> set CLASSPATH=%DERBY_INSTALL%libderby.jar;%DERBY_INSTALL%libderbytools.jar;%DERBY_INSTALL%libderbyoptionaltools.jar;%DERBY_INSTALL%libderbyshared.jar;.
UNIX:$ export CLASSPATH=$DERBY_INSTALL/lib/derby.jar:$DERBY_INSTALL/lib/derbytools.jar:$DERBY_INSTALL/lib/derbyoptionaltools.jar:$DERBY_INSTALL/lib/derbyshared.jar:.
Notice that multiple entries in the class path are separated by asemicolon (;) on Windows and a colon (:) on UNIX.
The Derby software provides another way to set CLASSPATH, using shell scripts (UNIX) and batch files (Windows). This tutorial shows how to set CLASSPATH explicitly and also how to use the Derby scripts to set it.
Change directory now into the DERBY_INSTALL/bin directory. The setEmbeddedCP.bat (Windows) and setEmbeddedCP (UNIX) scripts use the DERBY_INSTALL variable to set the CLASSPATH for Derby embedded usage. You can edit the script itself to set DERBY_INSTALL, or you can let the script get DERBY_INSTALL from your environment. Since you already set DERBY_INSTALL in the 'Set DERBY_INSTALL' section above, you don't need to edit the script, so go ahead and execute it as shown below:
Windows:C:> cd %DERBY_INSTALL%binC:Apachedb-derby-10.15.2.0-binbin> setEmbeddedCP.bat
UNIX:$ cd $DERBY_INSTALL/bin$ . setEmbeddedCP
Verify Derby
Run the sysinfo command, as shown below, to output Derbysystem information:
java org.apache.derby.tools.sysinfo
Successful output will look something like this:

Install 10.15.6
The output on your system will probably be somewhat different from the output shown above, but it should reflect the correct location of jar files on your machine and there shouldn't be any errors. If you see an error like the one below, it means your class path is not correctly set:
$ java org.apache.derby.tools.sysinfoException in thread 'main' java.lang.NoClassDefFoundError: org/apache/derby/tools/sysinfo
Install 10.15.3
Echo your CLASSPATH, as shown below,then double check each entry in your class path to verify that the jar file is where you expect it:
Install Mac Os 10.15
Windows:C:> echo %CLASSPATH% C:ApacheDB-DER~1.1-Blibderby.jar;C:ApacheDB-DER~1.1-Blibderbytools.jar;C:ApacheDB-DER~1.1-Blibderbyoptionaltools.jar;C:ApacheDB-DER~1.1-Blibderbyshared.jar;

Install 10.15 On Unsupported Mac
If sysinfo outputs valid information, you'reready to move to 'Step 2: ij Basics'.
