Error getting while using JODconverter

[sagar priyadarshi]

Hi

Encouraged by some group member, I divided my work in 2 stage.
1. any format to pdf and
2. pdf to jpeg using imagemagick


I downloaded "jodconverter-core-3.0-beta-3-

dist.zip" and then after unzipping that i could see "jodconverter-core-3.0-beta-3.jar" in lib folder.
On command line i typed

java -jar jodconverter-core-3.0-beta-3.jar test.odt test.pdf   (test.odt is in the same directory)
Below is the error I am getting:

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/artofsolving/jodconverter/cli/Convert (Unsupported major.minor version 49.0)

        at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:302)


I am using openoffice 2.4 and Java version is 1.4.2_17

Kindly help me to get the proper output.
