(i hope that i, post this topic to the right list!)
I� m trying to insert a new node to a xml file and
save it after that with a servlet. When I use the same
Code in a not Servlet version I have no problem and
can open, read and insert new node to xml file.
But when I try to do it in a servlet (use almost the
same code but in a servlet version) and I call
document.getDocumentElement() from a procedure I get
only null pointer!
Is that maybe because servlet cant find the xml Tree
in
RAM??? how could i do it?
I use tomcat plugin 4.1_29, win XP and eclipse 3.0M5
Here is a piece of code where I
document.getDocumentElement()try to save it
��
Document document;
DOMParser parser = new DOMParser ()
parser.parse("E:/eclipse/workspace/project/userlist1.xml");
document = parser.getDocument();
public void read( )
{
//read and parse userlist1.xml
}
��..
��
public void saveXmlTree( )
{
try
{ String content="";
FileWriter writer = new FileWriter
("E:/eclipse/workspace/project/userlist2.xml");
BufferedWriter output = new BufferedWriter(writer);
//I write xml Tree to userlist2.xml file
String header = "<?xml version = '1.0' encoding =
'iso-8859-1' ?> \n";
content = header+
document.getDocumentElement().toString();
writer.write(content,0,content.length());
output.close();
}catch (IOException ioe){}
}
As Result in userlist2.xml file I get:
[userlist: null]
And here is a piece of userlist1.xml
"<?xml version = '1.0' encoding = 'iso-8859-1' ?>
<userlist>
<user>
<name>tom</name>
<pass>0987</pass>
<nr>987769</nr>
<address>xxx street 56</address>
</user>
<user>
<name>dan</name>
<pass>9876</pass>
<nr>987769</nr>
<address>cccc street 678</address>
</user>
</userlist>
I will be very, very thankful if somebody could help
me.
