将使用 struts 2.3 jar 构建的 Ear 部署到 weblogic 服务器时出现上述异常
struts.xml

I get above exception on deploying ear built using struts 2.3 jars to weblogic server

请告诉我如何解决这个问题.

推荐答案

我更改了解决错误的构建脚本虽然不知道以前的构建脚本有什么问题(可能是以前的构建脚本导致了 jars 冲突)).

I changed the build script which resolved the error though do not know what was wrong with previous build script(may be previous build script was causing jars conflict).

    <!-- ==================== Clean Target ==================================== -->

    <!--
      The "clean" target deletes any previous "build" and "dist" directory,
      so that you can be ensured the application can be built from scratch.

    <!-- ==================== Init Target ================================== -->

      The "init" target is used to create the "build" destination directory,
      Normally, this task is executed indirectly when needed.

    <!-- ==================== Compile Target ================================== -->

    <!--

      The "compile" target transforms source files (from your "src" directory)
      into class files in the appropriate location in the build directory.
      This example assumes that you will be including your classes in an
      unpacked directory hierarchy under "/WEB-INF/classes".
