Question

I am developing an mobile application using j2me.In that i am using kxml parser.In my application i have to call an url to get the data.When i am calling that url sometimes it showing:

java.lang.IllegalStateException: update of non-existent node   Exception.

My sample code is:

 InputStreamReader isr=null;
        InputStream rssStream=null;
        InputStream is = null;
        HttpConnection conn=null;
        try
        {          
            conn = (HttpConnection)Connector.open(rssUrl);           
            rssStream = conn.openInputStream();---------->I think exception is shown here.         
            isr = new InputStreamReader( rssStream );
            parser.setInput(isr);
            parser.nextTag();

Answer 1

Better you replace the code

 rssStream = conn.openInputStream();---------->I think exception is shown here.         
 isr = new InputStreamReader( rssStream );

with the following code

isr = conn.openInputStream();

Then try it.
