RE: ArrayStoreException in get*Array() method in custom Ant task

[Radu Preotiuc-Pietro]

Yeah, it does smell like one of those esoteric classloader issues. Do you also use substitution groups in this context? (looks like there probably are global element definitions corresponding to itenQueryDefinition, changeRequestQueryDefinition and fileQueryDefinition)

 

So what is happening is that XmlBeans doesn't have access to one of the generated resources so it can resolve the subst group. The resource name should be "schemaorg_apache_xmlbeans/element/URI_SHA_1_1DD80F3162A834D56F4BECF11C9343A1641FECC5/item_2Dquery.xsb" and the classloader should be com.commerce360.internal.cm.starteam.query.xml.QueryDefinitionSetXmlBean.class.getClassLoader() (hope I'm getting this right...). In order to debug this you can resource load that and see if ant makes it available to you, as a first step.

 

I'd appreciate it if you would let us know if get more info out of debugging this

Thanks,

Radu

I left out some of the stacktrace:

 

java.lang.ArrayStoreException

        at java.lang.System.arraycopy(Native Method)

Subject: ArrayStoreException in get*Array() method in custom Ant task

Fellow XMLBeans users,

 

I have an xmlbean and some code that uses the xmlbean. The code works as expected when launched from the java command-line

or launched via Ant's 'java' task. I wrote a simple Ant custom task to run the code. When the custom task is executed an ArrayStoreException is thrown in the bean's get*Array() method. I'm using XMLBeans 2.1.0 and Ant 1.6.4. Below is a snippet from the stacktrace:

 

     java.lang.ArrayStoreException

        at com.commerce360.internal.cm.starteam.query.xml.impl.QueryDefinitionSetXmlBeanImpl.getQueryArray(QueryDefinitionSetXmlBeanImpl.java:59)

 

The XSD fragment for the bean looks like this:

<xs:complexType name="queryDefinitionSet">
       
        <xs:sequence>
            <xs:element ref="query" maxOccurs="unbounded" minOccurs="0"/>
        </xs:sequence>
       
    </xs:complexType>

 

   <xs:complexType name="queryDefinition" abstract="true">
       
        <xs:sequence>  
           
            <xs:element name="id" type="xs:ID" maxOccurs="1"/>
 
        </xs:sequence>
       
    </xs:complexType>
   
    <xs:complexType name="itemQueryDefinition" abstract="true">
        <xs:complexContent>
            <xs:extension base="queryDefinition">         
                <xs:sequence>
 
                </xs:sequence>
            </xs:extension>
        </xs:complexContent>
    </xs:complexType>
   
    <xs:complexType name="changeRequestQueryDefinition">
        <xs:complexContent>
            <xs:extension base="itemQueryDefinition">         
                <xs:sequence>
 
                </xs:sequence>
            </xs:extension>
        </xs:complexContent>
    </xs:complexType>
   
    <xs:complexType name="fileQueryDefinition">
        <xs:complexContent>
            <xs:extension base="itemQueryDefinition">         
                <xs:sequence>
                   
                </xs:sequence>
            </xs:extension>
        </xs:complexContent>
    </xs:complexType>
   
    <xs:element name="query" type="queryDefinition"/>

The code generated for the xmlbean's getQueryArray() method looks like this:

 

public class QueryDefinitionSetXmlBeanImpl extends org.apache.xmlbeans.impl.values.XmlComplexContentImpl implements com.commerce360.internal.cm.starteam.query.xml.QueryDefinitionSetXmlBean
{
   
    public QueryDefinitionSetXmlBeanImpl(org.apache.xmlbeans.SchemaType sType)
    {
        super(sType);
    }
   
    private static final javax.xml.namespace.QName QUERY$0 =
        new javax.xml.namespace.QName("http://www.360commerce.com/internal/starteam/query/xml", "query");
    private static final org.apache.xmlbeans.QNameSet QUERY$1 = org.apache.xmlbeans.QNameSet.forArray(

        new javax.xml.namespace.QName[] {
        new javax.xml.namespace.QName("http://www.360commerce.com/internal/starteam/query/xml", "item-query"),
        new javax.xml.namespace.QName("http://www.360commerce.com/internal/starteam/query/xml", "file-query"),
        new javax.xml.namespace.QName("http://www.360commerce.com/internal/starteam/query/xml", "change-request-query"),
        new javax.xml.namespace.QName("http://www.360commerce.com/internal/starteam/query/xml", "query"),
    });
   
   
    /**
     * Gets array of all "query" elements
     */
    public com.commerce360.internal.cm.starteam.query.xml.QueryDefinitionXmlBean[] getQueryArray()
    {
        synchronized (monitor())
        {
            check_orphaned();
            java.util.List targetList = new java.util.ArrayList();
            get_store().find_all_element_users(QUERY$1, targetList);
            com.commerce360.internal.cm.starteam.query.xml.QueryDefinitionXmlBean[] result = new 

                                          com.commerce360.internal.cm.starteam.query.xml.QueryDefinitionXmlBean[targetList.size()];
            targetList.toArray(result);
            return result;
        }
    }
   

     .....

     .....

     ......

 

}

 

 

 

The exception occurs at the 'targetList.toArray(result)' line. What's happening is that when the code is run as a custom ant task,

the class of the elements in the 'targetList' ArrayList is 'org.apache.xmlbeans.impl.values.XmlAnyTypeImpl' whereas when the same code

is successfully run as a command-line java app, the class is 'com.commerce360.internal.cm.starteam.query.xml.impl.ChangeRequestQueryDefinitionXmlBeanImpl'. I am using the same classpath

and input XML in both cases.

 

I did some googling and found another person who experienced the same exception but over RMI:

 

http://mail-archives.apache.org/mod_mbox/xmlbeans-user/200310.mbox/[EMAIL PROTECTED]

 

Does anyone have insight as to why the XMLBeans unmarshalling code would type my objects as XmlAnyTypeImpl when

run as a custom Ant task? This smells like one of those esoteric classloader issues and I suspect it requires a deeper knowlegde of XMLBeans

internals than I currently have to debug it.

 

Any help or insights would be appreciated.

 

Thanks,
