Question

 And some times i m getting java.net.MalFormedURLException what s the reason behind this and how can i resolve this..

My code is as follows..


SAXParserFactory spf = SAXParserFactory.newInstance();
        SAXParser sp = spf.newSAXParser();
        XMLReader xr = sp.getXMLReader();

        /** Send URL to parse XML Tags */
        URL sourceUrl = new URL(
                "http://w3devadv.liveproj.com  /api/apiRequest.php?Method=getdealdetails&DealId=2&SessionId=EA3JQ0RZJT4e66223143fc5");

        /**
         * Create handler to handle XML Tags ( extends DefaultHandler )
         */
        DealsHandler myXMLHandler = new DealsHandler();
        xr.setContentHandler(myXMLHandler);
        xr.parse(new InputSource(sourceUrl.openStream()));


In handler i m writing the following code in startelement  

public void startElement(String uri, String localName, String qName,
        Attributes attributes) throws SAXException {
    currentElement = true;
    if (localName.equalsIgnoreCase("data")) {
        dealsdata = new DealsData();
    } else if (localName.equalsIgnoreCase("dealdetails")) {
        deals = new Deals();
    } else if (localName.equalsIgnoreCase("title")) {
        deals.title = attributes.getLocalName(0);
    }

i m getting the above said exception how can i resolve this.

Answer 1

You are getting this error because.....

"This exception is thrown when a program attempts to create an URL from an
incorrect specification."

Answer 2

before passing the string to url you can Convert the string to Standard URL format

这种做法。

String url = new String(str.trim().replace(" ", "%20").replace("&", "%26")
.replace(",", "%2c").replace("(", "%28").replace(")", "%29")
.replace("!", "%21").replace("=", "%3D").replace("<", "%3C")
.replace(">", "%3E").replace("#", "%23").replace("$", "%24")
.replace(" ", "%27").replace("*", "%2A").replace("-", "%2D")
.replace(".", "%2E").replace("/", "%2F").replace(":", "%3A")
.replace(";", "%3B").replace("?", "%3F").replace("@", "%40")
.replace("[", "%5B").replace("\", "%5C").replace("]", "%5D")
.replace("_", "%5F").replace("`", "%60").replace("{", "%7B")
.replace("|", "%7C").replace("}", "%7D"));

你们可以在你任满时使用“URL”这一功能,这样你就可以克服错误,做你的工作。

i know you accepted the answer but this could also help other also i think Thank You.

Answer 3

"http://w3devadv.liveproj.com  /api/apiRequest.php?Method=getdealdetails&DealId=2&SessionId=EA3JQ0RZJT4e66223143fc5"

It is probably due to the space in the URL.
