请参阅下面的简单代码（myfile.jar）。这在 Eclipse 下编译和运行良好。当我导出为 Jar runnable 时，出现以下错误。我找到了文件“.../Java/jfreechart-1.5.3/org/jfree/chart/plot/LocalizationBundle_ca.properties”。

该文件在 CLASSPATH 中！它位于“org.jfree.chart.plot”包中。

如何链接 myfile.jar 和此文件？我去了不同的帖子，发现了一些提示，但对我来说没有任何用处。

我的文件

import org.jfree.chart.ChartFactory;
import org.jfree.chart.JFreeChart;

public class TestMain {

    public static void main(String[] args) {
        JFreeChart chart = ChartFactory.createTimeSeriesChart(null, "Time", "Y-axis", null, true, true, false);
    }
}

输出：
