This chapter takes you through the process of setting up Apache POI on Windows and Linux based systems. Apache POI can be easily installed and integrated with your current Java environment following a few simple steps without any complex setup procedures. User administration is required while installation.
System Requirements JDK Java SE 2 JDK 1.5 or above Memory 1 GB RAM (recommended) Disk Space No minimum requirement Operating System Version Windows XP or above, Linux Let us now proceed with the steps to install Apache POI. Step 1: Verify your Java Installation First of all, you need to have Java Software Development Kit (SDK) installed on your system. To verify this, execute any of the two commands depending on the platform you are working on. If the Java installation has been done properly, then it will display the current version and specification of your Java installation. A sample output is given in the following table.
Platform Command Sample Output Windows Open command console and type − java –version Java version '1.7.060' Java (TM) SE Run Time Environment (build 1.7.060-b19) Java Hotspot (TM) 64-bit Server VM (build 24.60-b09,mixed mode) Linux Open command terminal and type − $java –version java version '1.7.025' Open JDK Runtime Environment (rhel-2.3.10.4.el64-x8664) Open JDK 64-Bit Server VM (build 23.7-b01, mixed mode). We assume the readers of this tutorial have Java SDK version 1.7.060 installed on their system. In case you do not have Java SDK, download its current version from and have it installed. Step 2: Set your Java Environment Set the environment variable JAVAHOME to point to the base directory location where Java is installed on your machine. For example, Sr.No.
Platform & Description 1 Windows Set JAVAHOME to C: ProgramFiles java jdk1.7.060 2 Linux Export JAVAHOME = /usr/local/java-current Append the full path of Java compiler location to the System Path. Platform & Description 1 Windows Append the String 'C: Program Files Java jdk1.7.060 bin' to the end of the system variable PATH.
2 Linux Export PATH = $PATH:$JAVAHOME/bin/ Execute the command java -version from the command prompt as explained above. Step 3: Install Apache POI Library Download the latest version of Apache POI from and unzip its contents to a folder from where the required libraries can be linked to your Java program. Let us assume the files are collected in a folder on C drive.
The following images show the directories and the file structure inside the downloaded folder. Add the complete path of the five jars as highlighted in the above image to the CLASSPATH. Platform & Description 1 Windows Append the following strings to the end of the user variable CLASSPATH − “C: poi-3.9 poi-3.9-20121203.jar;” “C: poi-3.9 poi-ooxml-3.9-20121203.jar;” “C: poi-3.9 poi-ooxml-schemas-3.9-20121203.jar;” “C: poi-3.9 ooxml-lib dom4j-1.6.1.jar;” “C: poi-3.9 ooxml-lib xmlbeans-2.3.0.jar.;” 2 Linux Export CLASSPATH = $CLASSPATH: /usr/share/poi-3.9/poi-3.9-20121203.tar: /usr/share/poi-3.9/poi-ooxml-schemas-3.9-20121203.tar: /usr/share/poi-3.9/poi-ooxml-3.9-20121203.tar: /usr/share/poi-3.9/ooxml-lib/dom4j-1.6.1.tar: /usr/share/poi-3.9/ooxml-lib/xmlbeans-2.3.0.tar.
