Fine on one machine, NoSuchMethodError exception on another

[filonenko]

Hello,

I'm using JFreeChart_1.0.17 with JCommon_1.0.21.

When I run my java project on one machine, it works fine, but when I try it on another one it fails with an exception:

Code: Select all

Exception in thread "main" java.lang.NoSuchMethodError: org.jfree.chart.ChartFactory.createXYStepChart(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Lorg/jfree/data/xy/XYDataset;)Lorg/jfree/chart/JFreeChart;

The same with createXYLineChart either createScatterPlot instead of createXYStepChart - ChartFactory methods. In the same time I have no problem using XYSeries, for example.

Both machines run under Ubuntu 12.04 for OS.
Java: OpenJDK, version "1.7.0_65", from ubuntu repositories.

No, there're no duplicate references on the classpath and no forgotten older versions of JFreeChart or JCommon.

Can you please help me, what can I be probably missing or what may be wrong, so that I get the error on one machine and don't get it on the other?
Any your ideas will be appreciated.

Looks like I have solved this.
There were no duplicate references on the classpath and no forgotten older versions of JFreeChart or JCommon - in mine project, in the part created by me and in the command I used to launch it.
But finally I have discovered an older version of JFreeChart inside a 3rd party library (jar-file). This did not influence the whole project while I was developping it on one machine. But when I moved copies of project onto other machines, on one of the machines smth. might have changed in a random fashion the order in which the libraries were picked from the classpath folder during the launch. The conflict emerged.
Thanks for your attention.

Thanks for the followup. Duplicate classes seem to cause the strangest error messages
