I'm looking to run a jython/modjy (modjy is kinda analogous to mod_wsgi except it bridges java web servers and applications) on my IBM WAS 8.5 Liberty Profile.

However when I convert the jython-modjy sample app into a .WAR file and put it in the dropins directory, the WebSphere server really struggles to find the path of the demo_app.py (WSGI handler). Here's a snippet of my web.xml file:

<init-param>
  <param-name>python.home</param-name>
  <param-value>C:/jython2.5.3</param-value>
</init-param>
<init-param>
  <param-name>app_filename</param-name>
  <param-value>demo_app.py</param-value>
</init-param>

The only other app related parameters are app_directory and app_callable_name which default to the current directory and handler respectfully:

I get the following error when I try to run the app:

modjy.modjy_exceptions.ApplicationNotFound: Application filename not found: None/demo_app.py

The only way I've gotten it to work is by specifying an absolute path, which really isn't too portable

Any help would be greatly appreciated

Thanks, David

我自己做了一个快速测试，我和 bkail 提出了同样的担忧。此问题很可能是 Liberty 未膨胀已部署的 Web 应用程序行为的结果。因此，所有依赖的应用程序getRealPath()都会失败。

有两种可能的选项/解决方法：

  1. 在开发环境中，您可以将 Eclipse 与 WebSphere Application Server Liberty Profile Tools 一起使用，以将您的动态 Web 模块项目添加到您的 Liberty 服务器实例。这将在 Liberty 和您的工作区中的项目文件之间创建一个链接。Servlet 上下文的getRealPath()方法将在此设置中工作。

  2. 将 Liberty 服务器dropins目录中的 WAR 文件扩展为一个目录，该目录与 WAR 文件类似，包括文件扩展名.war. 同样的方法应该适用于在server.xml.
