thanks,

try changing the content-type to text/xml or application/xml...
Also, pass the PrintWriter object, i.e pw to readdata function and in readData function, use PrintWriter object to output xml data instead of System.out.println();

[madhuri kunchala]

hi prasad,
i tried..but im unable to view..im getting output as..

<b>Xml File Viewed Successfully</b>

but i need is my full xml file..

hi prasad,
i tried what you had given..im not getting the xml file..im getting the output as

[Prasad Krishnegowda]

I tried in my PC, its working.. By, the By, You are viewing the XML file, or creating a new file.. i.e MyXml.xml, is alredy existing or not..

[Prasad Krishnegowda]

Anyway, Here is the code, copied form my system, which is working.. please let me know, if you still have any problems...
In the below code, just change the

    File xmlfile = new File("D:\\Cisco-XML works\\Stage4\\Combined\\XML\\1.xml") 

part to refer to your XML file..

You are welcome...

[Prasad Krishnegowda]

Why exactly are you using config.properties, because, here i see, you are giving login.xml file name, directly..

[madhuri kunchala]

i had sended you to your inbox message

[Prasad Krishnegowda]

I would recommend, you to use getResourceAsStream for loading .properties file.. Anyway, are you sure, your properties file is loaded, try printing gprsLoginPath, bfore appending Login.xml and see, what it is printing..

[madhuri kunchala]

i tried ..it is taking and printing the value what i had given

[Prasad Krishnegowda]

Then, what it is showing in the browser, any exception, or blank page..

[madhuri kunchala]

i changed the code like this

   

gprsLoginPath = propObj.getProperty("GPRS_LOGIN_PATH");
            if (gprsLoginPath == null || gprsLoginPath.trim().equals("")) {
                gprsLoginPath = excelTemplatesPath;
                
            }
            System.out.println(gprsLoginPath);
                System.out.println("hello");

and the output is

'E:/proj/gprs
hello'

[Prasad Krishnegowda]

That is fine.. What is the error you are getting, not able to view the XML file, means, are you getting any exception? or blank page?

[madhuri kunchala]

im getting error as

XML Parsing Error: junk after document element
Location: http://localhost:8080/proj/viewXml
Line Number 254, Column 1:<b>Xml File Viewed Successfully</b>
^

[Prasad Krishnegowda]

comment out this

  pw.println("<b>Xml File Viewed Successfully</b>");     

line, and tell, what you are getting...
