获取JAVA EE Server中已安装服务器的路径

Question

I need the main path from my OS of my installed JAVA EE Server (Wildfly) on which is the web app currently running.

So for example: If the JAVA EE Server (Wilfly) is installed at: C:/Software/myApp/myServer

Than I need exactly this location. How can I do this. It could be that there is another instance for Wildfly, so I cannot use the System variable.

Answer 1

Try System.getProperty("jboss.home.dir") .

Anyway, depending on the installation location is a bit of a design smell.

Answer 2

Unfortunately your description of your question was not clearly, because EJB is business logic and not directly your web app, also when you deploy all within your war file. Because the EJB has no information about the request itself except it is a webservice with JAXWS.

When you only need the root path to your server and not the web app then you can use like @Harald Wellmann wrote : System.getProperty("jboss.home.dir") and you will get the root path of your server.

If you need the path to your app then you could use for example

    this.getClass().getProtectionDomain().getCodeSource().getLocation()

which will give you as standard behavior the path to your /WEB-INF/classes folder.

If you would use JSF, JSP or Servlets, then it is much simpler and you could get the information directly through the HttpServletRequest object with getServletContext().getRealPath("/") like I wrote before.

And with an EJB with JAXWS you could inject get the HttpServletRequest object like this:

    @Context
    private HttpServletRequest httpRequest;

Answer 3

Path to server dir (server/bin):

File inputFile = new File("file.xml"); // server_dir/bin/file.xml

Path to other server directories, "webapps" for example:

File inputFile = new File("../webapps/file.xml"); // server_dir/webapps/file.xml

Good way to get rid of the absolute paths :) Tested on Tomcat, but hopefully it will help.
