I have built a XML record on Taminothat has elements with an array. I can access the other elements of the object, but when I try and access the children elements I get an array error:
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
at java.util.ArrayList.RangeCheck(ArrayList.java:511)
at java.util.ArrayList.get(ArrayList.java:327)
at com.softwareag.tamino.db.API.examples.greeting.query.main(query.java:150)
Exception in thread “main”
Java code:
StringWriter stringWriter = new StringWriter();
response.getFirstXMLObject().writeTo( stringWriter);
System.out.println( “Retrieved following instance:” + stringWriter );
String data = “Collection”;
// this stest the commit to local
// TLocalTransaction localTransaction = connection.useLocalTransactionMode();
while (test1.hasNext())
{
TXMLObject xmlObject1 = test1.next();
Element e = (Element) xmlObject1.getElement();
List list = e.elements(tagName);
Element elem = (Element) list.get(0);
elem.node(0).getStringValue();
data = (elem.node(0).getStringValue()) ;
System.out.println(“Before update” + data);
TXMLObject xmlobject = test1.next();
System.out.println(“i got xmlobject object”);
Element t = (Element) xmlobject.getElement();
List tlist = t.elements(“taxkey”);
Element taxkey_elem = (Element) tlist.get(0);
String taxkey = taxkey_elem.node(0).getStringValue();
Element oe = (Element) xmlobject.getElement();
list = oe.elements(“report_line”);
Element levy_year_elem = (Element) list.get(0);
String levy_year = levy_year_elem.node(0).getStringValue();
System.out.println(taxkey);
System.out.println(levy_year);
System.out.print(" (");
System.out.print(“ino:id="” + xmlobject.getId() + "" ");
System.out.print(“collection="” + xmlobject.getCollection() + “" “);
System.out.print(“doctype="” + xmlobject.getDoctype() + “" “);
System.out.println(”)”);
// response = xmlObjectAccessor.update(xmlObject1);
// End of Update
//System.out.println(” Update completed”);
}
The XML is :

What Document Object Model are you using; JDOM or DOM? I don’t recognise this combination of Classes and Methods in your code:
Element e = (Element) xmlObject1.getElement();
List list = e.elements(tagName);
Could you please post all of the code, the xml instance and the corresponding schema as a zip file, then I can try to help more.
Thanks.
Included is the results from console, the schema ad the java source code

You’re using DOM4J. I’m not sure what some of your code is for (you’re doing another query when you already have the report line data available) but maybe thats just because I don’t understand your data? Anyway, to iterate through your report lines I changed your code like this and it seems to work:
while (test1.hasNext()) {
TXMLObject xmlObject1 = test1.next();
Element e = (Element) xmlObject1.getElement();
List list = e.elements(tagName);
Element elem = (Element) list.get(0);
elem.node(0).getStringValue();
data = (elem.node(0).getStringValue());
System.out.println("Taxkey" + data);
elem.setText(data);
// don't use next() without checking that its really available....
TXMLObject xmlobject = xmlObject1;
System.out.println("i got xmlobject object");
Element oe = (Element) xmlobject.getElement();
List listoe = oe.elements("Collection");
int lengthList = listoe.size();
Element levy_year_elem2 = (Element) listoe.get(0);
List listrl = levy_year_elem2.elements("report_line");
int lengthrl = listrl.size();
for (int j=0;j<lengthrl;j++)
{
Element reportLine = (Element) listrl.get(j);
String report_line = reportLine.getStringValue();
System.out.println("report_line" + report_line + "J" + j);
}
System.out.print(" (");
System.out.print("ino:id=\"" + xmlobject.getId() + "\" ");
System.out.print(
"collection=\"" + xmlobject.getCollection() + "\" ");
System.out.print("doctype=\"" + xmlobject.getDoctype() + "\" ");
System.out.println(")");
}
