As Felix already mentioned, JMeter variables are not the same as script variables. Please re-read the thread, and the JMeter manual, particularly: http://jakarta.apache.org/jmeter/usermanual/component_reference.html#BeanShell_Sampler > And where can I find the reference about functions in BSH like prev.getTime()? JMeter Javadoc, as mentioned at the end of http://jakarta.apache.org/jmeter/usermanual/component_reference.html#BeanShell_Sampler > -- > View this message in context: > http://jmeter.512774.n5.nabble.com/How-to-get-transaction-time-into-a-user-defined-variable-tp3328587p3330594.html > Sent from the JMeter - User mailing list archive at Nabble.com. > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [email protected] > For additional commands, e-mail: [email protected] > > --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
