applet - java.lang.NoClassDefFoundError 与我的小程序

Question

我的应用程序中有一个小程序，当我调用我的 jsp 时出现此错误

java.lang.ClassNotFoundException: VisualisationCourbeCharge.class at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadClass0(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source) at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source)

我的代码:

    StringBuffer applet = new StringBuffer();
    applet.append("<object classid=\"clsid:8AD9C840-044E-11D1-B3E9-00805F499D93\" ");
    applet.append("width = \"750\" height = \"500\" hspace = \"0\" vspace = \"0\" align = \"middle\">\n");
    applet.append("\t<param name=\"archive\" value=\"jfreechart-0.9.8.jar,jcommon-0.8.0.jar\">\n");
    applet.append("\t<param name=\"codebase\" value=\"./ihm/applet/graphe/\">\n");
    applet.append("\t<param name=\"code\" value=\"VisualisationCourbeCharge.class\">\n");
    applet.append("\t<param name=\"");
    applet.append(ConstantesApplet.PARAMETRE_LANGUE);
    applet.append("\" value=\"");
    applet.append(langue);
    applet.append("\">\n");

Answer 1

将后续的 jar 文件添加到服务器中。 @Moataz Elmasry 的建议很好。

将您的jar 文件放入特定目录。 即/bin
