Programmers can integrate Apache Tika in their environment by using
Command line,
Tika API,
Command line interface (CLI) of Tika,
Graphical User interface (GUI) of Tika, or
the source code.
For any of these approaches, first of all, you have to download the source code of Tika.
You will find the source code of Tika at https://Tika.apache.org/download.html, where you will find two links −
apache-tika-1.6-src.zip − It contains the source code of Tika, and
apache-tika-1.6-src.zip − It contains the source code of Tika, and
Tika -app-1.6.jar − It is a jar file that contains the Tika application.
Tika -app-1.6.jar − It is a jar file that contains the Tika application.
Download these two files. A snapshot of the official website of Tika is shown below.
After downloading the files, set the classpath for the jar file tika-app-1.6.jar. Add the complete path of the jar file as shown in the table below.
Export CLASSPATH = $CLASSPATH −
/usr/share/jars/Tika-app-1.6.tar −
Apache provides Tika application, a Graphical User Interface (GUI) application using Eclipse.
