问题

我有一个使用Eclipse开发的动态Web项目，转换为了Maven项目。

我已经导出了WAR包，并将其部署到了HEROKU上。

问题是：

java.io.IOException: 无法运行程序“/app/target/tomcat.21601/webapps/expanded/lib/binary”：错误=13，权限被拒绝

这个二进制文件是由Servlet调用来执行一些操作的，但可能需要使用chmod命令进行设置。

从Heroku控制台，我找不到可以访问这个二进制文件并运行chmod命令的方法，因为WAR包不是一个目录。

我应该如何在Heroku服务器上为Web应用程序中的二进制文件运行chmod命令？

英文:

I have a Dynamic Web Project, developed with Eclipse, converted in a Maven project.

I have exported the WAR, and i have deployed it on HEROKU.

The issue is :

java.io.IOException: Cannot run program &quot;/app/target/tomcat.21601/webapps/expanded/lib/binary&quot;: error=13, Permission denied

This binary is called by the servlet for doing some stuffs, but maybe it needs chmod command.

From the Heroku console, I can't find a way to reach the binary and run chmod, cause the WAR is not a directory.

How I can chmod a binary that is part of Web application, on the Heroku machine?
