Re: [Simple-support] Does not understand this ElementException

Hi,

>From this I can tell one of your XML elements named "SignedDataObject" does not have an "id" attribute. Look in your XML file at line 43, I think you will see there is no "Id" element, set the @Attribute(name="Id", required=false) this should fix it. Also, without seeing the class DigestAlgAndValueType I cannot tell if it has an @Element matching "DigestMethod", though Ill bet there is no such element. A good option for you might be.

Persister.read(MyClass.class, mySourceStream, false) // false means ignore elements and attributes not matched by your annotations

Subject: [Simple-support] Does not understand this ElementException

Hello,

I have a little problem with Simple. First, here is a part of my XSD file:

<xs:complexType name="SignedDataObjectType">
    <xs:sequence>
     <xs:element name="Encapsulated" type="xs:boolean"/>
     <xs:element name="MimeType" type="xs:string"/>
     <xs:element name="Name" type="xs:string" minOccurs="0"/>
     <xs:element name="Description" type="xs:string" minOccurs="0"/>
     <xs:element name="Size" type="xs:long" minOccurs="0"/>
     <xs:element name="DigestAlgAndValue" type="xad:DigestAlgAndValueType" minOccurs="0"/>
     <xs:element name="Revisions" type="vt:RevisionsType" minOccurs="0"/>
     <xs:element name="Errors" type="vt:ErrorsType" minOccurs="0"/>
    </xs:sequence>
    <xs:attribute name="Id" type="xs:ID" use="required"/>
   </xs:complexType>

Then, here is my targetted Java class:

public class SignedDataObjectType {

	@Attribute(name = "Id")
	protected String id;

	@Element(name = "Encapsulated")
	protected boolean encapsulated;

	@Element(name = "MimeType")
	public String mimeType;

	@Element(name = "Name", required = false)
	protected String name;

	@Element(name = "Description", required = false)
	protected String description;

	@Element(name = "Size", required = false)
	protected Long size;

	@Element(name = "DigestAlgAndValue", required = false)
	protected DigestAlgAndValueType digestAlgAndValue;

	@Element(name = "Revisions", required = false)
	protected RevisionsType revisions;

	@Element(name = "Errors", required = false)
	protected ErrorsType errors;

... setters and getters here...

And to finish, a the part of my XML file:
... other datas here...
<vt:SignedDataObject Id="signeddata-1">
	<vt:Encapsulated>true</vt:Encapsulated>
	<vt:MimeType>application/pdf</vt:MimeType>
	<vt:Name>signeddata-1.pdf</vt:Name>
	<vt:Size>131323</vt:Size>
	<vt:DigestAlgAndValue>
		<ds:DigestMethod Algorithm="1.3.14.3.2.26"></ds:DigestMethod>
		<ds:DigestValue>KuWqL3YVcSMZeHRov5nE90PZSeY=</ds:DigestValue>
	</vt:DigestAlgAndValue>
</vt:SignedDataObject>
... other datas here...

And I have this exception:

org.simpleframework.xml.core.ValueRequiredException: Unable to satisfy @org.simpleframework.xml.Attribute(empty=, name=Id, required=true) on field 'id' protected java.lang.String com.lexpersona.lp7verifybox.entities.SignedDataObjectType.id for class com.lexpersona.lp7verifybox.entities.SignedDataObjectType at line 43 at org.simpleframework.xml.core.Composite.validate(Composite.java:644)
at org.simpleframework.xml.core.Composite.readAttributes(Composite.java:416)
...blah blah blah...

As you can see, the datas exists. So, I tried to use the required false (which is very bad because my class attributes are mandatory) in the annotation but I have another exception with the DigestAlgAndValue tag:

org.simpleframework.xml.core.ElementException: Element 'DigestMethod' does not have a match in class com.lexpersona.lp7verifybox.entities.SignedDataObjectType at line 48 at org.simpleframework.xml.core.Composite.readElement(Composite.java:527)
... blah blah blah...

I do not understand why Simple is against me at this level :s And you can note the I already use the DigestAlgAndValue element before and that works... I realy do not understand why Exception are thrown in this level :(

Have you any ideas? Do I need to send you more informations?
