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

Radu,

Actually the file schemaorg_apache_xmlbeans/element/URI_SHA_1_1DD80F3162A834D56F4BECF11C9343A1641FECC5/item_2Dquery.xsb

is in the jar. I just overlooked it. I modified my test code to load the resource and it loaded fine.

Two questions:

1) Do you know offhand which class handles the loading of the .xsb resources. I'm going to look at the source.

2) Does XML beans generate log messages during the XML marshalling/unmarshalling and loading of .xsb resources?

If so, I'd like to enable it in the hopes it may help me debug this problem.

Thanks for the help,

Ok, so we know that the classloader loads all the resources you would expect it to.

However, the fact that "schemaorg_apache_xmlbeans/element/URI_SHA_1_1DD80F3162A834D56F4BECF11C9343A1641FECC5/item_2Dquery.xsb" is missing is a problem and will result in the exception that you are seeing. Moreover, if I compile the Schema snippet that you provided and look inside the generated jar, that resource is there so I don't know how it got removed in your environment.

So you need to recompile and get the new jar under ant and everything will, hopefully, be fine.

And yeah, if anyone looked inside a jar generated by XmlBeans and wondered what was up with the "URI_SHA_1_1DD80F3162A834D56F4BECF11C9343A1641FECC5" strings, they are just the SHA-1 hash of the targetNamespace in the Schema.

Thanks,

Radu

Radu,

I wrote some code to load the following resources from the xmlbeans-generated-jar:

schemaorg_apache_xmlbeans/type/URI_SHA_1_1DD80F3162A834D56F4BECF11C9343A1641FECC5/queryDefinition.xsb
schemaorg_apache_xmlbeans/type/URI_SHA_1_1DD80F3162A834D56F4BECF11C9343A1641FECC5/itemQueryDefinition.xsb
schemaorg_apache_xmlbeans/type/URI_SHA_1_1DD80F3162A834D56F4BECF11C9343A1641FECC5/changeRequestQueryDefinition.xsb
schemaorg_apache_xmlbeans/type/URI_SHA_1_1DD80F3162A834D56F4BECF11C9343A1641FECC5/fileQueryDefinition.xsb

I was able to load all the resources when the code was executed from my Ant task.

Below is the code I used to test the resource loading:

            String[] res = {
                    "schemaorg_apache_xmlbeans/type/URI_SHA_1_1DD80F3162A834D56F4BECF11C9343A1641FECC5/queryDefinition.xsb",

                    "schemaorg_apache_xmlbeans/type/URI_SHA_1_1DD80F3162A834D56F4BECF11C9343A1641FECC5/itemQueryDefinition.xsb",
                    "schemaorg_apache_xmlbeans/type/URI_SHA_1_1DD80F3162A834D56F4BECF11C9343A1641FECC5/fileQueryDefinition.xsb",
                    "schemaorg_apache_xmlbeans/type/URI_SHA_1_1DD80F3162A834D56F4BECF11C9343A1641FECC5/changeRequestQueryDefinition.xsb"
                           };

            for (int i = 0; i < res.length; i++)
            {
                URL resUrl = QueryDefinitionSetXmlBean.class.getClassLoader().getResource(res[i]);
                if (resUrl == null)
                {
                    System.out.println("Failed to load resource " + res[i]);
                }
                else
                {
                    System.out.println("Loaded resource " + resUrl);
                }
            }

And the Ant output from my "starteam-query" custom task:

Radu,

The names of the relevant .xsb resources for this XMLBean in the generated jar are:

There is no resource named:

schemaorg_apache_xmlbeans/element/URI_SHA_1_1DD80F3162A834D56F4BECF11C9343A1641FECC5/item_2Dquery.xsb

Is this what you would expect?

Thanks for the help Radu! I'll test out the resource load using the xmlbean's classloader and let you know how it works out.

What puzzles me somewhat is why it (XMLBeans, the java classloader, etc) can't find the resource even if the resource is in the same jar as the

xmlbean class file. Have you encountered anything similar in Ant or elsewhere? Also, how did you know the name of resource it expects is

"schemaorg_apache_xmlbeans/element/URI_SHA_1_1DD80F3162A834D56F4BECF11C9343A1641FECC5/item_2Dquery.xsb"?

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

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,

-- Tellis
