我有一个工作将web应用程序从Tomcat迁移到Weblogic12，我让war使用了Tomcat webapp文件夹下的所有文件，然后将war复制到weblogic的autodeploy文件夹中，启动weblogic服务器以使应用程序自动部署. 然后出现如下错误：

似乎 web-inf lib 文件夹中的 jar 加载失败。weblogic启动时生成的“/opt/Corizo​​n/CPv434_Interim/UIService/runtime/user_projects/domains/corizo​​n/servers/AdminServer/tmp/_WL_user/_appsdir_UIService_war/e44ur4/war/WEB-INF/lib”中的_wl_cls_gen.jar.why应该生成这个 jar

任何人都知道原因将不胜感激。

更新（ConfigHelper类）：

URL markerURL = Thread.currentThread().getContextClassLoader().getResource("classes-marker");
markerURL=JBossVFSManager.convert(markerURL);
if(markerURL!=null) {
    final String markerPath = markerURL.getPath();
    mWebInfClassesPath = markerPath.substring(0, markerPath.lastIndexOf("classes-marker"));
    if (!new File(mWebInfClassesPath).exists()) {
        throw new IllegalStateException("Could not determine WEB-INF directory (marker URL was '" + markerPath + "').");
    }
    mConfigPath = mWebInfClassesPath + DEFAULTSYSTEMPROPERTIESPATH;
}
