checkout from svn using ant

I am trying to checkout from svn using ant from Linux machine. I have written build.xml but it is showing me the error.

build.xml:

<?xml version="1.0"?>
<project name="SVN" default="build" basedir=".">
<property name="ANT_HOME" value="/dun/d67loc1/software/apache-ant-1.6.5"/>
<path id="svnant.classpath">
<pathelement location="${ANT_HOME}/lib"/>
<fileset dir="${ANT_HOME}/lib/">
<include name="**/*.jar"/>
</fileset>
</path>
<typedef resource="org/tigris/subversion/svnant/svnantlib.xml" classpathref="svnant.classpath"/>
<target name="checkout">
<echo>svn checkout </echo>
<svn username="...." password="....">
<checkout url="https://svm.acnielsen.com/repos/IDOArchitecture/Ascent/Bin/Config/trunk/Production/TIBCO/FavConfig" destPath="SRC" />
</svn>
</target>
<target name="build" depends="checkout">
<description>Main target</description>
</target>
</project>

While executing it I am getting the below error:

Buildfile: build.xml

      [svn] <Checkout> started ...

Please check the .bash Profile for Java Home it should point to actual JDK home and JRE version. If it points to right directory it will be ok.
