## What is Apache Xerces Environment Setup?

This section takes you through the process of setting up Apache Xerces on Windows and Linux based systems. Apache Xerces 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 Xerces.

### 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, complete any of the two commands depending on the platform you are working on.
If the Java installation has been done correctly, then it will display the current version and specification of your Java installation. A sample output is given in the subsequent 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: $java -version java version "1.7.0_25" Open JDK Runtime Environment (rhel-2.3.10.4.el6_4-x86_64) Open JDK 64-Bit Server VM (build 23.7-b01, mixed mode) • We assume the readers of this tutorial have Java SDK version 1.7.0_60 installed on their system. • In case you do not have Java SDK, download its current version from http://www.oracle.com/technetwork/java/javase/downloads/index.html and have it installed. ### Step 2: Set your Java Environment Set the environment variable JAVA_HOME to point to the base directory location where Java is installed on your machine. For example,  Platform Description Windows Set JAVA_HOME to C:\ProgramFiles\java\jdk1.7.0_60 Linux Export JAVA_HOME=/usr/local/java-current Append the full path of Java compiler location to the System Path.  Platform Description Windows Linux Append the String "C:\Program Files\Java\jdk1.7.0_60\bin" to the end of the system variable PATH. Export PATH=$PATH:$JAVA_HOME/bin/ Execute the command java -version from the command prompt as explained above. ### Step 3: Install Apache Xerces Library Download the latest version of Apache Xerces from here and unzip its contents to a folder from where the required libraries can be linked to your Java program. Let us assume the files are collected in a folder xerces-2_11_0 on C drive. Add the complete path of the five jars as highlighted in the above image to the CLASSPATH.  Platform Description Windows Append the following strings to the end of the user variable CLASSPATH: C:\xerces-2_11_0\resolver.jar; C:\xerces-2_11_0\serializer.jar; C:\xerces-2_11_0\xercesImpl.jar; C:\xerces-2_11_0\xercesSamples.jar; C:\xerces-2_11_0\xml-apis.jar; Linux Export CLASSPATH=$CLASSPATH: /usr/share/xerces-2_11_0\resolver.jar: /usr/share/xerces-2_11_0\serializer.jar: /usr/share/xerces-2_11_0\xercesImpl.jar: /usr/share/xerces-2_11_0\xercesSamples.jar: /usr/share/xerces-2_11_0\xml-apis.jar:
