Converting URL to file path

Question

I have a file in one of the folders of my webapp running in Tomcat. I need to convert the URL to the file to an absolute file path so that I can read it.
The URL looks like
http://localhost:28080/tester/custom/reports/transform.xsl
I tried creating a FIle object:
File file = new File(url.getFile());
But file.getAbsolutePath() returns
C:\tester\custom\reports\transform.xsl
It should be:
C:\Program Files\Apache Group\Tomcat 4.1\webapps\tester\custom\reports\transform.xsl
Any ideas?

Answer 1

ok, i succeeded in using URL to get stream as
follows:
String path = getBaseUrl() + "/" + "custom" + "/"
+ "reports";
String hostname =
InetAddress.getByName(InetAddress.getLocalHost().getHo
stAddress()).getHostName();
String urltest = "http://" + hostname + ":28080" +
path + "/transform.xsl";
URL url = new URL(urltest);
InputStream xsltStream =
url.openConnection().getInputStream();
where getBaseUrl() is a function that return the
context name
But another related question? How do I get the port
number.How do you get the port starting form where? From the URL? If so, URL has a getPort method.
