Nokia SDK 1.1 for java get Null when read XML File

[thanhlnh]

I have a XML file

<Smileys>
<Smiley>
<Key></Key>
<Value>/Emoticon/smiley_1.png</Value>
</Smiley>
<Smiley>
<Key>:~</Key>
<Value>/Emoticon/smiley_2.png</Value>
</Smiley>
</Smileys>

with a source code

Vector tagVector = null;
InputStream is = null;
InputStreamReader isr = null;
try {
is = class.getResourceAsStream(Setting.EMOTICON_PATH);
isr = new InputStreamReader(is, "utf-8");
XMLParser myParser = new XMLParser();
Element e = myParser.parse(isr);
tagVector = e.getChildrenByTagName("Smiley");
} catch (Exception ex) {
return;
}

I got java.lang.NullPointerException on Nokia SDK 1.1 for java, but also all of sdk "S40_5th_Edition_SDK,S40_5th_Edition_SDK_Feature_Pack_1,S40_6th_Edition_SDK...." is not have error

Hi thanhlnh,

I couldn't reproduce the NullPointerException on neither Nokia SDK 1.1 nor S40_5th_Edition_SDK when I tested your code with LWUIT 1.5 and the following minor modifications:

		Vector tagVector = null;
		InputStream is = null;
		InputStreamReader isr = null;
		try { 
			is = getClass().getResourceAsStream("file.xml");
			isr = new InputStreamReader(is, "utf-8");
			XMLParser myParser = new XMLParser();
			Element e = myParser.parse(isr);
			tagVector = e.getChildrenByTagName("Smiley");
			System.out.println("Size of Elements: " + tagVector.size());
		} catch (Exception ex) {
		return;
		}

The last print statement could be reached and I could get "Size of Elements: 2" on my console.

I only copied pasted your xml file, called it file.xml and placed it in the res directory of my Eclipse's working project. Instead of using the instance class, I used the method getClass().

This could be related to how Setting.EMOTICON_PATH is evaluated on runtime.
Also ensure that you are using the latest version of LWUIT.
