Reading text files in JSP pages

I want to know if it's possible to read a file and display it in an html:text area on a jsp page.
What I have right now is:
<html:file property="theFile" style="query-table-item" onclick="uploadFile(document.searchReportForm.theFile);"/> <html:reset title="Reset"/>what I wish to do, is to implement the uploadFile function, so that it can read from a text file and display it's contents onto the html:file area.
uploadFile is a javascript function that is being called from a javascript file.
I want to know if I can read the browsed file using javascript.
and if so, does someone have an idea how to do it?
Please help me out.

Reading text file in jsp

hi,
i have a txt file...which i am reading in my jsp page using bufferedreader class, to read txt file i have to type the absolute path of txt file as c:/myproject/xxx.txt
how can i access this txt file with relative path as xxx.txt instead of typing the absolute path c:/myproject/xxx.txt
any suggestions
Thanks

2 options:
1) Put this file in one of the existing paths of the classpath, or add the path to this file to the classpath. Then use ClassLoader#getResourceAsStream() to get an inputstream of it based on the given file name.
2) Put this file in the webcontent. Then use ServletContext#getRealPath() to convert the given relative web path to an absolute filesystem path and finally use it in the constructor of FileInputStream to get an inputstream of it.

How can i render a dynamic html file in jsp page

Hi everybody,
i am trying to render a dynamic html file in jsp page with the result of querying a database.
The response of the query is a xml document. And i have a stylesheet to transfer it to html.
How can i render the html in a jsp file?

I am using below code for HTML files
private var appFile:String="index.html";
if (StageWebView.isSupported)
                    currentState = "normal";
                    webView.stage = stage;
                    webView.viewPort = new Rectangle( 10, 130, (stage.stageWidth)-20, 750 );
                    var fPath:String = new File(new File("app:/assets/html/aboutus/"+ appFile).nativePath).url;
                    webView.loadURL(fPath);
                    addEventListener(ViewNavigatorEvent.REMOVING,onRemove);
                else {
                    currentState = "unsupported";
                    lblSupport.text = "StageWebView feature not supported";
above code is working fine for me.

How to call text file in jsp

Hi all,
I can call html or jsp file from jsp file, but how can I call text file in jsp, I put my text file same lever asmy jsp file it don't work!
where I should put the text file??
thank you

mary,
since you knew the file name ,when clicked in name send to server,read the file and write to servlet outputstream.
I think this would help you.
If anything wrong in mycode ..forums will help you further
BufferedInputStream bis=null;
BufferedOutputStream bos=null;
int bytesRead=0;
byte buff[]=new byte[1024];
File f=new File(test.txt);
try{
     bis= new BufferedInputStream(new FileInputStream(f));
     bytesRead=bis.read(buff,0,buff.length);
     if(bytesRead!=-1){
          // create a BufferedOutputStream from ServletOutputStream
          bos=new BufferedInputStream(response.getOutputStream());
          do{
               bos.write(buff,0,bytesRead);
          }while((bytesRead=bis.read(buff,0,buff.length))!=-1)
}catch(Exception e){
     ////error handling
     }

How can i call java class file in jsp page

Hai,
i wants to call .class file in jsp page.
my class file is in C:\jsdk\bin.
Thanks

I'm not entirely sure what you mean by "calling a class file", but I'm going to assume that you want to do something like the following in your page:
<%
MyClass myClass = new MyClass();
myClass.someMethod();
%>etc
If that's the case, then all you have to do is make sure that the class is in the servlet engine's classpath. You'll probably also need to include an appropriate import statement at the top of the page.
Hope that helps.

Reading text file to JEditorPane

Hi,
I'm trying to read text file to JEditorPane and it works but first line is always missing. Here is the code for reading:
try {
   in = new BufferedReader(new FileReader(filePathIn));
   while ((lineIn = in.readLine()) != null) {
        editorPane.read(in, new Object());
} catch (IOException ie)...Any suggestions?

in.readLine is changing the input stream position.
Do this instead:
FileInputStream in = new FileInputStream(filePathIn);
while (in.available() != 0)
    editorPane.read(in, new Object());

How can I read text files from LAN if I only know the hostname?

I'm new in Java Developing, and dont know the written classes yet. I need help, how to do the following steps?
<p>1. How can I read text files from LAN if I only know the hostname, or IP address?
<p>2. How to read lines from text files without read all lines from the beginning of file, just seek to a position.
(ex. how can I read the 120th line?)
<p>Please help!
<p>sorry for the bad english

I'm new in Java Developing, and dont know the written classes yet. I need help, how to do the following steps?
1. How can I read text files from LAN if I only know the hostname, or IP address?You need to know the URL of the file. You need to know the hostname, port, protocl and relative path.
The hostname is server, not file.
2. How to read lines from text files without read all lines from the beginning of file, just seek to a position.Use the seek() to get to a random byte.
(ex. how can I read the 120th line?)The only way to find the 120th line is to read the first 120 lines. You can use other file formats to find the 120th line without reading the whole file but to need to be able to detremine where the 120th line is
