从当前线程获取Context

        try {
            //获取WebAppServletContext
            Field workEntry = Class.forName("weblogic.work.ExecuteThread").getDeclaredField("workEntry");
            workEntry.setAccessible(true);

            }
            resp.getWriter().println(webAppServletContext.getRootTempDir().getAbsolutePath());
            resp.getWriter().println(webAppServletContext.getAppName());
        }catch(Exception e){}
    }
}

从request处获取Context

weblogic.servlet.internal.WebAppServletContext servletContext = (WebAppServletContext) req.getServletContext();
resp.getWriter().write(servletContext.getAppName());
resp.getWriter().write(servletContext.getTempPath());

获取应用web目录物理路径

resp.getWriter().println(context.getRootTempDir().getAbsolutePath());
resp.getWriter().println(context.getAppName());
