illegal escape charcter error

[jyothsna ananthula]

hi all

please check the following code as illegal escape character.urgent please

import oracle.xml.differ.*;
import oracle.xml.parser.v2.*;
import java.io.*;

public class First {

    public static void main(String arg[])
    {
    DOMParser parser=new DOMParser();

    try{
        InputStream catalog1=new FileInputStream(new File("C:\Documents and Settings\JA0084604\Desktop\test1a.xml"));
   parser.parse(catalog1);
    }
    catch(Exception e){
        System.out.println(e);
    }

    }
}

The backslash \ character in string literals is the escape character. It allows you to write for example \n for a newline, \t for a tab etc.

If you write "C:\Documents and Settings\JA0084604\Desktop\test1a.xml" then Java is going to complain that \D and \J are illegal escape sequences. If you want to include a literal backslash in your string, you have to write \\ (two backslashes).

So, change the string to: "C:\\Documents and Settings\\JA0084604\\Desktop\\test1a.xml"

Please UseCodeTags when you post source code. Also, please EaseUp.

its urgent to me

Please EaseUp.

 }
}

any body help me out please.

I added code tags to your post to make it more legible. Next time, just highlight your code and click the little "code" button above - just like you wanted to make something italic or bold (but don't make your code italic or bold...)

To answer your question...

You declare your XMLDocument inside your try block. therefore, as soon as you go out of the try block the document falls out of scope, and thus doesn't exist anymore. The solution would be to declare them outside the try block, but still assign them inside...something like this:

public class Second{

    public static void main(String arg[])
    {
    DOMParser parser=new DOMParser();

   XMLDocument xmlDocument1=null;
   XMLDocument xmlDocument2=null;

    try{
        InputStream catalog1=new FileInputStream(new File("C:\\Documents and Settings\\JA0084604\\Desktop\\test1a.xml"));
   parser.parse(catalog1);
   xmlDocument1=parser.getDocument();
    }
    catch(Exception e){
        System.out.println(e);
    }


  try{
    InputStream catalog2=new FileInputStream(new
      File("C:\\Documents and Settings\\JA0084604\\Desktop\\test2a.xml"));
   parser.parse(catalog2);

   xmlDocument2=parser.getDocument();}
    catch(Exception e){
        System.out.println(e);
       }

    XMLDiff a=new XMLDiff();


    a.setDocuments(xmlDocument1,xmlDocument2);
 boolean diff=a.diff();
        System.out.println(diff);
 }
}

Note: I didn't actually test/compile this, so i'm not 100% sure i have it correct...
