isSet methods not generated using jaxb2-basics simplify plugin

I have a schema with two elements within a <xs:choice/> block, as per the following fragment:
<xs:complexType name="POCD_MT000040.Component2">
<xs:sequence>
<xs:element name="realmCode" type="CS" minOccurs="0" maxOccurs="unbounded"/>
<xs:element name="typeId" type="POCD_MT000040.InfrastructureRoot.typeId" minOccurs="0"/>
<xs:element name="templateId" type="II" minOccurs="0" maxOccurs="unbounded"/>
<xs:choice>
<xs:element name="nonXMLBody" type="POCD_MT000040.NonXMLBody"/>
<xs:element name="structuredBody" type="POCD_MT000040.StructuredBody"/>
</xs:choice>
</xs:sequence>
<xs:attribute name="nullFlavor" type="NullFlavor" use="optional"/>
<xs:attribute name="typeCode" type="ActRelationshipHasComponent" use="optional" fixed="COMP"/>
<xs:attribute name="contextConductionInd" type="bl" use="optional" fixed="true"/>
</xs:complexType>
This is part of the HL7/CDA specification schemas, by the way.
Well, I am using maven-jaxb2-plugin to generate the Java classes, with a touch of the jaxb2-basics plugin to simplify complex elements, like nonXMLBody and structuredBody. Let's say I have a bindings file with the following contents:
<jxb:bindings
xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
xmlns:simplify="http://jaxb2-commons.dev.java.net/basic/simplify"
jxb:extensionBindingPrefixes="xjc simplify"
version="2.1">
<jxb:globalBindings
typesafeEnumMaxMembers="1000"
generateMixedExtensions="true"
generateIsSetMethod="true"
choiceContentProperty="true">
<xjc:serializable uid="1" />
</jxb:globalBindings>
<jxb:bindings schemaLocation="xsd/POCD_MT000040.xsd">
<jxb:bindings node="xs:complexType[#name='POCD_MT000040.Component2']//xs:choice">
<simplify:as-element-property />
</jxb:bindings>
</jxb:bindings>
</jxb:bindings>
The attributes are generated as expected:
protected POCDMT000040NonXMLBody nonXMLBody;
protected POCDMT000040StructuredBody structuredBody;
However, although I am using generateIsSetMethod="true" in the global bindings, the methods isSetNonXMLBody ( ) and isSetStructuredBody ( ) are not being generated at all. The equivalent methods for the rest of the attributes are present, though, like isSetTypeId ( ).
Am I missing any option I should know of to generate these methods in the aforementioned elements?

XSD "property already defined"

I'm trying to use jaxb to compile some Veracode provided .xsd files
the "detailedreport.xsd" is throwing this error:
[ERROR] Property "Vulnerabilities" is already defined. Use <jaxb:property> to resolve this conflict.
line 930 of file:detailedreport.xsd
[ERROR] The following location is relevant to the above error
line 936 of detailedreport.xsd
when I look at the XSD file, I see that Vulnerabilities is both an attr and a type:
<xs:complexType name="Component">
<xs:annotation>
<xs:documentation>
The element describe the details of vulnerable component.
* file_paths: File paths of the component.
-----> * vulnerabilities : Vulnerabilities of the component.
* violated_policy_rules: Violated policy rules of the component.
* component_id: The id of the component.
* file_name: File name of the component.
-----> * vulnerabilities: Number of vulnerabilities available in the component.
* max_cvss_score: Max cvss_score of the component.
* library: Library name of the component.
* version: Version of the component.
* vendor: Vendor name of the component.
* description: Description about component.
* blacklisted: Component's blacklisted status.
* new: Component added newly.
* added_date: Component's added_date.
* component_affects_policy_compliance: COmponent's policy violation status.
* licenses: Contains license details of the component.
</xs:documentation>
</xs:annotation>
<xs:sequence>
<xs:element name="file_paths" minOccurs="0" maxOccurs="1" type="tns:FilePathList"/>
<xs:element name="licenses" minOccurs="0" maxOccurs="1" type="tns:LicenseList"/>
-----> <xs:element name="vulnerabilities" minOccurs="0" maxOccurs="1" type="tns:VulnerabilityList" />
<xs:element name="violated_policy_rules" minOccurs="0" maxOccurs="1" type="tns:ViolatedRuleList" />
</xs:sequence>
<xs:attribute name="component_id" type="xs:string" use="required"/>
<xs:attribute name="file_name" type="xs:string" use="required"/>
<xs:attribute name="sha1" type="xs:string" use="required"/>
-----> <xs:attribute name="vulnerabilities" type="xs:integer" use="required"/>

<xs:attribute name="new" type="xs:string"/>
<xs:attribute name="added_date" type="xs:string"/>
<xs:attribute name="component_affects_policy_compliance" type="xs:string"/>
</xs:complexType>
here's the xsd they publish: https://analysiscenter.veracode.com/resource/detailedreport.xsd
from what I can figure out, I need to create a detailedreport.xjb file and (as the output states) setup a <jaxb:property> to convert the vulnerabilities integer attribute into something like vulnerabilityCount.
I created detailedreport.xjb:
<?xml version="1.0" encoding="UTF-8"?>
<jaxb:bindings xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb">
<!-- Used to avoid the duplicate element/attribute name conflict -->
<jaxb:bindings node="//xsd:attribute[#name='vulnerabilities']">
<jaxb:property name="vulnerabilityCount"/>
</jaxb:bindings>
</jaxb:bindings>
but my xpath is wrong:
[ERROR] XPath evaluation of "//xsd:attribute[#name='vulnerabilities']" results in empty target node
line 10 of file: detailedreport.xjb
am I even on the right path
any xpath help is appreciated

One more bindins element referencing schema location should be provided:
<jxb:bindings
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
version="2.1"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
jxb:extensionBindingPrefixes="xjc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemalocation="http://java.sun.com/xml/ns/jaxb
http://java.sun.com/xml/ns/jaxb"
>
<jxb:bindings schemaLocation="PATH_TO_THE_SCHEMA" node="/xs:schema">
<jxb:bindings node="//xs:attribute[#name='vulnerabilities']">
<jxb:property name="vulnerabilityCount"/>
</jxb:bindings>
</jxb:bindings>
</jxb:bindings>
Path can be relative to xjb file, e.g.: schemaLocation="../detailedreport.xsd"

JAXB Unmarshalling of XML into HashMap

I have a complex XML Structure as below which needs to be unmarshalled:
<abc>
<pqr>
<attribute>name</attribute>
<entry>
<priorityKey>
<class>123</class>
<reason>abc</reason>
</prioritykey>
<priority> 1 </priority>
</entry>
<entry>
<prioritykey>
<class>456</class>
<reason>abc1</reason>
</prioritykey>
<priority>2</priority>
</entry>
</pqr>
<pqr>
'''
'''
</pqr>
</abc>
abc is the root node. It can have multiple pqr elements. Each pqr element has one attribute node and multiple entry nodes. So I believe it will be of type HashMap(entry,attribute).
Each entry in turn has prioritykey and priority which I believe will be of type HashMap (prioritykey,priority).
Need to unmarshall this xml but not getting how to configure the XMLAdapter

Here, create the contract first. I created one as part of my learning process...
<xs:element name="abc" type="abcType" />
<xs:complexType name="abcType">
<xs:sequence>
<xs:element name="pqr" type="pqrType" minOccurs="1"
maxOccurs="unbounded" />
</xs:sequence>
</xs:complexType>
<xs:complexType name="pqrType">
<xs:sequence>
<xs:element name="attribute" type="xs:string" minOccurs="1"
maxOccurs="1" />
<xs:element name="entry" type="entryType" minOccurs="1"
maxOccurs="unbounded" />
</xs:sequence>
</xs:complexType>
<xs:complexType name="entryType" >
<xs:sequence>
<xs:element name="priorityKey" type="priorityKeyType"
minOccurs="1" maxOccurs="1" />
<xs:element name="priority" type="xs:int" minOccurs="1"
maxOccurs="1" />
</xs:sequence>
</xs:complexType>
<xs:complexType name="priorityKeyType">
<xs:sequence>
<xs:element name="class" type="xs:int" minOccurs="1"
maxOccurs="1" />
<xs:element name="reason" type="xs:string" minOccurs="1"
maxOccurs="1" />
</xs:sequence>
</xs:complexType>
Copy and save this in an fileName.xsd file.
Now, generate JAXB classes or artifacts. If you are using an IDE, then this is simple. Click on the fileName.xsd file and you should get some option to generate JAXB artifacts. Otherwise, you can always use jaxb-xjc.jar present in the lib present in the JAXB download.
Command for the same - java -jar jaxb-xjc.jar fileName.xsd.
As the artifacts are in place, you can use them to unmarshall the xml content in question.

Error while generating JAXB model from xsd in eclipse

I am trying to generate JAXB model from the following xsd
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://abc.com/mmm/trt" attributeFormDefault="unqualified"
elementFormDefault="qualified">
<xs:annotation>
<xs:documentation>Schema for Cache Refresh Event.
</xs:documentation>
</xs:annotation>
<xs:simpleType name="cacheCode">
<xs:restriction base="xs:string">
<xs:enumeration value="BUSINESS_RULE" />
<xs:enumeration value="USER" />
</xs:restriction>
</xs:simpleType>
<xs:element name="cacheRefreshEvent">
<xs:complexType>
<xs:sequence>
<xs:element name="cacheCode" type="cacheCode" minOccurs="1"
maxOccurs="1" />
<xs:element name="entityRefId" type="xs:string" minOccurs="0"
maxOccurs="20" />
<xs:element name="cacheRefreshDate" type="xs:dateTime"
minOccurs="1" maxOccurs="1" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
But, it is giving me the following error, which i got in Eclipse console
parsing a schema...
[ERROR] src-resolve.4.1: Error resolving component 'cacheCode'. It was detected that 'cacheCode' has no namespace, but components with no target namespace are not referenceable from schema document 'file:/F:/Sprint6/cache/src/main/resources/CacheRefreshEvent.xsd'. If 'cacheCode' is intended to have a namespace, perhaps a prefix needs to be provided. If it is intended that 'cacheCode' has no namespace, then an 'import' without a "namespace" attribute should be added to 'file:/F:/Sprint6/cache/src/main/resources/CacheRefreshEvent.xsd'.
line 18 of file:/F:/Sprint6/cache/src/main/resources/CacheRefreshEvent.xsd
Failed to parse a schema.
Please help.

Remove this extra namespace attribute targetNamespace="http://www.hcentive.com/mea/trr"
OR add this xmlns="http://www.hcentive.com/mea/trr"
Both solutions will work :)
For you reference targetnamespace-and-xmlns

how to add validation in xsd for blank spaces

i have created basic xsd successfully however I want to add restriction for the element that it should be present and contains atleast one character. it also has 4 attributes. i am facing problem in adding restriction since I can not use simple type as the element has attributes.
Please suggest something
thanks in advance

You have to first create a simple type that restricts xsd:string to specify your text constraints. Then you need to define a complex type, with a simple content, which extends the simple type you just created using the attributes you want. I threw in a whitespace constraint, just to match your title, even though you're not specifically mention it in your problem statement.
