Issue using java.io.File

Posted: Feb 27, 2003 1:11 AM

Hi

Environment : Linux 7.2
JDK : 1.3
Tomcat : 4.1.18
APACHE : 1.3.27 (FYI)

I can not get the following code to work form a jsp page:

out.println("path : " + request.getContextPath());
File f = new File(request.getContextPath());
if (f.isDirectory()) {
out.println(f.getName()+" is directory");
}
File[] fs = f.listFiles();
if (fs != null) {
out.println(fs.length + "<BR>");
} else {
out.println("<BR>fs is null<BR>");
}
if (fs != null) {
int i;
for (i=0;i<fs.length;i++) {
out.println("<BR>"+fs.getName());
}
}

When I run the above code:

1. f is not null
2. fs is null
3. f.isDirectory is false
4. f.getAbsolutePath is /WEB-INF

basically I can not browse the directory structure.

Any help in this regard is appreciated.

Regards

You probably have your jsp file in the wrong folder.

Only the resource files you don't want users to be able to browse through should be under /WEB-INF

that is where you put class and jar files.
class files go under the /WEB-INF/classes folder
jars under the /WEB-INF/lib folder

Your jsp file will probably compile and run if you stick it under the webapps/ROOT folder.

Its got to be in a visible spot, the same as htm or html web page files.

If you are using the default Tomcat install, the index page (index.htm, index.html, index.jsp, default.htm, etc.) will come up if you ask for http://localhost:8080/

Add a link to the index page to your jsp to access it from the index page.
