JSP Tree Structure

[prasath03]

Hi,

I am struggling with the following problem. Can somebody pls help me?.

I have a file name and have a folder File f1= new File("path of the folder");. The folder is a complicated folder structure i.e. contains various files and sub folders which contains further subfolders etc. I want to show the whole folder structure(like tree structure). But, the following code shows only the "WebContent" structure.Please find below the following code:

File f1 = new File("D:/eclipse/workspace/cms/WebContent");
File[] contents = f1.listFiles();
for (int j=0; j<contents.length; j++) 
{
 
    if(contents[j].isDirectory())
    {
        out.println("Directory : "+contents[j].getName()+"<br/>");
    }
    else
    {
        out.println("Files :"+contents[j].getName()+"<br/>");
    }
 
}
 

If anybody knows the answer, please let me know....

Thanks in Advance,

make a method from your source, pass as parameter the path (that what you hardcoded in f1), and then call your method recursively. That means, if it's a directory, call yourself with new path parameter, made up of old path+current directory name.

Ok, herewith I let you know that I know. :-)

Classes and methods are the basics of Java programming. If you don't know how to define a method with parameters, then do Sun's Java tutorial first to get the basic knowledge.

If you know how to write a method, but you don't know how to do that in JSP, read the jsp tutorials. For a quick start, I'll give you an example:

<%!
private String printFolder(String fullFolderName)
{
 return "printFolder was called with: " + fullFolderName;
}
%>
 
Now I am calling my method. It returns:
<%= printFolder("root") %>
