I am using Jasper Ireport 5.1.0

I have installed my java:

C:jdk1_7_11

I have installed my jasper:

C:Program Files (x86)JaspersoftiReport-5.1.0etc

my system is 64bit windows7 and i set java path home in ireport.conf like this

# ${HOME} will be replaced by user home directory according to platform
default_userdir="${HOME}/.${APPNAME}/5.1.0"
default_mac_userdir="${HOME}/Library/Application Support/${APPNAME}/5.1.0"

# options used by the launcher by default, can be overridden by explicit
# command line switches
default_options="--branding ireport -J-Xms256m -J-Xmx512m -J-Dorg.netbeans.ProxyClassLoader.level=1000 -J-XX:MaxPermSize=512m"
# for development purposes you may wish to append: -J-Dnetbeans.logger.console=true -J-ea

# default location of JDK/JRE, can be overridden by using --jdkhome <dir> switch
#jdkhome="C:jdk1_7_11"

# clusters' paths separated by path.separator (semicolon on Windows, colon on Unices)
#extra_clusters=
