Hi folks ,

Im a biginner in xml parsing .I have my "spin.xml" file in E dir. Im using Netbeans 5.0 for my game development. i want to parse the xml file to get its content into my mobile or emulator. Please tell me the basic steps i have to follow. I got one sample program for xml parsing which uses

FileConnection fc = (FileCOnnection)Connector.open("file:///root1/helloword.xml");

So i replaced it by

FileConnection fc = (FileCOnnection)Connector.open("file:///E:/spin.xml");

But its throwing IO EXP: "Root not accesible"

plz suggest where(which folder) should i store the xml file to get it in emulator and phone.

thanks in advance....

yafy.

Hi yafi,

Well, if your target device implements JSR-75 then you should go that way. Otherwise, include you XML file as a resource within your JAR file.

Regarding your doubts related to directories and files i advise you to read this doc:

Introduction To The FileConnection API (With Example) v1.1
http://www.forum.nokia.com/info/sw.n..._v1_1.zip.html

Take a look at the doc below for good information regarding XML parsing in JME:

XML in J2ME
http://trix2.cellmania.com/downloads...E_20060301.pdf

Forum Nokia also has a document that briefly discuss the JSR-172 XML parsing optional package (the standard way). Check it out, page 6.

MIDP: Web Services API Developer's Guide (With Example)
http://www.forum.nokia.com/info/sw.n..._v1_0.zip.html

I hope it helps!

BR,

Juarez

and if you are using netbeans and WTK emualtor, you need to find the emulators root file system on your PC's file system

for example in Win2k and XP, mine is
D:\Documents and Settings\Jay\.netbeans\4.1\emulators\wtk22_win\emulator\wtk22\appdb\DefaultColorPhone\filesystem\root1

using e of your hard drive, wont work, if thats what your trying, note the bolded above, this is where the emulators file system begins

so you would place your xml file in there

Try this, use kxml2


/*

import java.io.InputStreamReader;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import org.kxml2.io.KXmlParser;
import org.xmlpull.v1.XmlPullParser;

/**

*/
public class AddressMidlet extends MIDlet implements Runnable
{
InputStreamReader ip;
KXmlParser parser;
Thread t;
String tag,text;

public void startApp()
{
t=new Thread(this);
t.start();
}

public void pauseApp() {
}

public void destroyApp(boolean unconditional) {
}

public void run()
{
try{
ip= new InputStreamReader(this.getClass().getResourceAsStream("/address.xml"));
parser= new KXmlParser();
parser.setInput(ip);

parser.nextTag();
parser.require(XmlPullParser.START_TAG, null, "address_book");
System.out.println("111111111");
while(parser.nextTag()!=XmlPullParser.END_TAG)
{
parser.require(XmlPullParser.START_TAG, null , "address");

while(parser.nextTag()!=XmlPullParser.END_TAG)
{
tag=parser.getName();
text=parser.nextText();
System.out.println(tag+" <<<::>>> "+text);
parser.require(XmlPullParser.END_TAG, null , tag);
}
}

parser.require(XmlPullParser.END_TAG,null, "address_book");
parser.next();
parser.require(XmlPullParser.END_DOCUMENT,null,null);
}catch(Exception e){System.out.println("errorrrrr "+e);e.printStackTrace();}
}

}


address.xml look like this


<address_book>
- <address>
<name>Robert Cadena</name>
<street_1>5555 Fake Street</street_1>
<street_2>Suit 202</street_2>
<city>Fake City</city>
<state>CA</state>
<zipcode>900099</zipcode>
</address>
- <address>
<name>Fake Name</name>
<street_1>3232 Another Street</street_1>
<city>Another City</city>
<state>TX</state>
<zipcode>79999</zipcode>
</address>
- <address>
<name>Manjul</name>
<street_1>1119/5</street_1>
<city>Gurgaon</city>
<state>Haryana</state>
<zipcode>122055</zipcode>
</address>
</address_book>

Hi all,

this is common mistake done by every one, guys keep on accessing file system simply using File(.....)

it is only possible by using jsr75 else not.

or supply a file with jar.
