Hi Andrej,
Our OM tree can contain two types of nodes, namely; OMText and
OMElement.
The OMElement will contain eii of the xml and OMText will contain
character ii. Your WSDL (or whatever xml) is having both texts and
elements under the document element. So casting children.next() to
either OMText or OMElement will DEFINITELY give you a CCE.
If you just want to print out an XML, use OMOutput.
XMLStreamReader
parser = XMLInputFactory.newInstance().createXMLStreamReader(
new
FileReader("ServisFirstTry1.wsdl"));
StAXOMBuilder builder = new
StAXOMBuilder(OMAbstractFactory.getOMFactory(), parser);
OMElement root = builder.getDocumentElement();
OMOutputImpl out = new OMOutputImpl(System.out, false);
root.serialize(out);
out.flush();
But I think you want to do
more than just dumping a WSDL :-)
Better read some of the tutorials on the web on AXIOM.

Hi,
I am trying to parse a WSDL file, so I could print out the contents by
its elements. The file is attached.
I am using the following code:
XMLStreamReader parser =
XMLInputFactory.newInstance().createXMLStreamReader(
new
FileReader("ServisFirstTry1.wsdl"));
StAXOMBuilder builder = new
StAXOMBuilder(OMAbstractFactory.getOMFactory(), parser);
OMElement root = builder.getDocumentElement();
System.out.println("WSDL print ");
System.out.println("--------------------------------------------------");
int i = 0;
Iterator children = root.getChildren();
while (children.hasNext()) {
System.out.print(i+": "); i++;
OMElement node = (OMElement) children.next(); // <---
exception here!
System.out.println(node.getFirstElement().getText());
}
but I get the following exception:
Exception in thread "main" java.lang.ClassCastException:
org.apache.axis2.om.impl.llom.OMTextImpl
at izpisWSDL.main(izpisWSDL.java:57)
if I use OMText instead of OMElement a different exception occurs. Any
help?
Thanks in advance,
Andrej
