Issue is iam getting NaN value for Min, Max in html reports.

Please let me know any solutions.

Answer 1

This problem is encountered in newer versions of Java.

I faced the same problem and this solution worked for me - Copy xalan-2.7.1.jar and serializer-2.7.1.jar from the apache-jmeter/lib folder and include it in apache-ant/lib folder of ant.

Somehow it's a problem related to newer Java versions: If you use Java 1.5 or higher it wont work out of the box, unless you:

1. Use the build file: http://svn.apache.org/repos/asf/jmeter/trunk/extras/build.xml
2. Include xalan.jar and serializer.jar both in jmeter lib directory

There are two bugs in apache bugzilla regarding this issue. More info:

Given it works in XP and not windows 7, try running in either:

• As Administrator
• Compatibility mode
