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 '1.7.0_60' Java (TM) SE Run Time Environment (build 1.7.0_60-b19) Java Hotspot (TM) 64-bit Server VM (build 24.60-b09,mixed mode) |
| Linux | Open command terminal and type − $java –version | java version '1.7.0_25' Open JDK Runtime Environment (rhel-2.3.10.4.el6_4-x86_64) Open JDK 64-Bit Server VM (build 23.7-b01, mixed mode) |
We assume the readers of this tutorial have Java SDK version 1.7.0_60 installed on their system.
In case you do not have Java SDK, download its current version from https://www.oracle.com/technetwork/java/javase/downloads/index.html and have it installed.
Step 2: Set your Java Environment
Set the environment variable JAVA_HOME to point to the base directory location where Java is installed on your machine. For example,
| Sr.No. | Platform & Description |
|---|---|
| 1 | Windows Set JAVA_HOME to C:ProgramFilesjavajdk1.7.0_60 |

Export JAVA_HOME = /usr/local/java-current |
Append the full path of Java compiler location to the System Path.
| Sr.No. | Platform & Description |
|---|---|
| 1 | Windows Append the String 'C:Program FilesJavajdk1.7.0_60bin' to the end of the system variable PATH. |
| 2 | Linux Export PATH = $PATH:$JAVA_HOME/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 https://poi.apache.org/download.html 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.
| Sr.No. | Platform & Description |
|---|---|
| 1 | Windows Append the following strings to the end of the user variable CLASSPATH − “C:poi-3.9poi-3.9-20121203.jar;” “C:poi-3.9poi-ooxml-3.9-20121203.jar;” Thepiratebay se torrent 6738156 native instruments maschine sound library update mac os x. “C:poi-3.9poi-ooxml-schemas-3.9-20121203.jar;” “C:poi-3.9ooxml-libdom4j-1.6.1.jar;” “C:poi-3.9ooxml-libxmlbeans-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 |
