Can you in the meantime post the actual NPE that you are getting with (at least a few levels of) the stacktrace? I don't think I have ever seen it in this thread. It's not clear to me where is the null coming from. Depending on that, it may be a legitimate NPE or not...

Don, since you have raised a good point in your last email, I will only ask one question in response to your 3rd point. Does the validate function only validate the schema or does it validate the values in the class? I'm unclear on how it works. I will talk to the people who came up with the schema, and at the very least look at the portions of the code where I get the NPE and see if it has a minOccurs 0. If it doesn't, then I will try to get that fixed. If it does, should I really be getting a NPE?

Jason, 3 points. 1) It is an inner portion of PlanningContextHeaderType that I changed :- </xs:annotation> <xs:element name="OPLAN"> <xs:complexType> To </xs:annotation> <xs:sequence> <xs:element name="OPLAN"> <xs:complexType> I have never personnally seen the NPE from Xmlbeans in the situation you are in. 2) Also have you looked at using :- isNil public boolean isNil() True if the value is nil. Note that in order to be nil, the value must be in an element, and the element containing the value must be marked as nillable in the schema. 3) One final point after the line PlanningContextHeaderType planContext = PlanningContextHeaderType.Factory.parse(inputFile); You do not seem to be checking planContext.validate() to ensure you get true i.e. valid input to continue. Cheers Don -----Original Message----- From: Green, Jason M. [mailto:[EMAIL PROTECTED] Sent: 03 October 2005 14:24 To: dev@xmlbeans.apache.org Subject: RE: NEED XMLBEANS HELP!!! Don, the schema that I had shown was only a portion and did not have all the outer portions shown. I will ask the owners of the schema about the nillable="true" portion. Why can't that return null when I try to access it instead of throwing the exception? Jason -----Original Message----- From: Don Stewart [mailto:[EMAIL PROTECTED] Sent: Monday, October 03, 2005 9:19 AM To: dev@xmlbeans.apache.org Subject: RE: NEED XMLBEANS HELP!!! Jason, Looking at the schema in the document are you sure it is valid ? You have an element <xs:element name="OPLAN"> within a <xs:complexType name="PlanningContextHeaderType"> Not within a <sequence> | <group> | <all> | <choice> . So is it not the case that <xs:complexType name="PlanningContextHeaderType"> <xs:annotation> <xs:documentation>Complex Type containing the planning context information for a document.</xs:documentation> </xs:annotation> <xs:element name="OPLAN"> <xs:complexType> <xs:sequence> <xs:element name="planId" type="xs:string"/> <xs:element name="name" type="xs:string"/> <xs:element name="aor" type="xs:string" minOccurs="0"/> <xs:element name="aorShape" type="AbsoluteLocationType" minOccurs="0"/> </xs:sequence> </xs:complexType> </xs:element> </xs:complexType> Should in fact be:- <?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"; elementFormDefault="qualified" attributeFormDefault="unqualified"> <xs:complexType name="PlanningContextHeaderType"> <xs:annotation> <xs:documentation>Complex Type containing the planning context information for a document.</xs:documentation> </xs:annotation> <xs:sequence> <xs:element name="OPLAN"> <xs:complexType> <xs:sequence> <xs:element name="planId" type="xs:string"/> <xs:element name="name" type="xs:string" nillable="true"/> <xs:element name="aor" type="xs:string" minOccurs="0"/> <!-- <xs:element name="aorShape" type="AbsoluteLocationType" minOccurs="0"/> --> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:schema> Also the elements that could be null should have be nillable="true".

Radu, I'm not quite sure what you mean by parsing. I'm under the impression that is what I was doing. I will show you the code I am using and you can let me know if I am doing it wrong? I do realize that there should be some error checking, but I thought I would be able to print out a null value without error. Please correct me if I am wrong. Here is my code: public static void main(String[] args) { String filePath = "C:\\Plans\\2.xml"; File inputFile = new File(filePath); try { MDADocumentDocument1 doc = MDADocumentDocument1.Factory.parse(inputFile); MDADocumentDocument1.MDADocument gdoc = doc.getMDADocument(); AnalysisViewType aView = gdoc.getDefenseDesignDocument(); PlanningContextHeaderType planContext = aView.getPlanningContextHeader(); PlanningContextHeaderType.OPLAN oplan = planContext.getOPLAN(); oplan.getName(); } catch(org.apache.xmlbeans.XmlException e) { System.out.println(e.toString()); } catch(IOException e1) { System.out.println(e1.toString()); } } It looks pretty simple. I know that I can't / won't put a try catch around every piece of data I'm trying to access.

This is not a question of parsing, it's a question of how you query your objects after parsing is done. In your example, you got the NPE while calling oplan.getName(); all you have to do is parse (no NPE will be thrown here regardless of the Schema and document), then use your planContext object as you would any other Java object, taking care that some of the fields may be null.

Actually, Let me rephrase the question: if I am reading in a bunch of documents that I am trying to parse. Not all of them will have the same data fields filled in. How will I be able to still parse without getting the nullpointer exception if a particular field is blank? -----Original Message----- From: Robin Sander [mailto:[EMAIL PROTECTED] Sent: Thursday, September 29, 2005 11:31 AM To: dev@xmlbeans.apache.org Subject: Re: NEED XMLBEANS HELP!!! Hello, as far as I can see you schema doesn't define a namespace, so how should XMLBeans know which schema to use? Try to specifiy a namespace or use the special 'noNamespace' namespace in your XML instance. Robin. Green, Jason M. wrote: > yana, > let me clarify.
