Hi there,
I'm trying to write a plugin that should do some XML handling.
The xml-file is loaded as an IFile to the local workspace. (so far so possible)
The next thing I want to do is to create a TreeViewer and fill it with the DOM of that XML file.
The code to create the TreeViewer reads like this:
(myStream is an IputStream from the IFile and Path is the filepath to the file on my local disc.)
| Code: |
public void createTreeView(InputStream myStream, String Path){
System.out.println("CreateTreeView");
treeView = new TreeViewer(window.getShell());
Document dom = new XMLStuff(myStream).getParser(Path);
treeView.add(dom, window.getWorkbench().getActiveWorkbenchWindow().getWorkbench());
}//public void CreateTreeView |
I'm trying to created parser with the following lines of code:
| Code: |
public Document getParser (String myPath){
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
try{
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document myDoc = docBuilder.parse(myPath);
return myDoc;
}catch(ParserConfigurationException PCE){
PCE.printStackTrace();
}catch(IOException IOE){
IOE.printStackTrace();
}catch(SAXException SAXE){
SAXE.printStackTrace();
}//catch SAXException
System.out.println("getParser returned null. sorry.");
return null;
}//public Document getParser (String myPath)
|
The actuall dom I' trying to achive should be create like this:
(XMLUtil is a part of the TPTP Project.)
| Code: |
public Element loadXMLDom(){
if (myStream != null){
System.gc();
//Hi there: The thing is that the following line causes a crash!
Element dom = XMLUtil.loadDom(myStream, "MWEB");
return dom;
}//if (myStream != null)
else
System.err.println("Sorry, but the Stream is null - loadXMLDom()");
return null;
}//public GetXMLDom
|
But both - the parser and the loadDom-function - do just return a Java Memory out of heap error.
Can someone please be so kind and tell me the reason for that?
Thank you in advance. |
