JAXB and ClassCastException

Hi all,
When I try to unmarshal a XML document, I get a ClassCastException. I've listed the details below. I've also searched the forums on this one but can't seem to find any answer (maybe I've missed it somewhere). I appreciate any help or hints anyone can offer.
XMLSchema: OrganizationalUnit.xsd
JAXB Generated classes: OrganizationalUnit.java, OrganizationalUnitType.java etc.
UnmarshallingCode:
JAXBContext jc = JAXBContext.newInstance("com.myproject.unitinfo");
Unmarshaller unmarshaller = jc.createUnmarshaller();
unmarshaller.setValidating(true);
String filename = JOptionPane.showInputDialog("Filename:");
OrganizationalUnit unit = (OrganizationalUnit)unmarshaller.unmarshal(new FileInputStream( filename ) );
System.out.println("Participant ID:" + unit.getUnitID() );The above code generates the following error:
ClassCastException caught.
com.iwise.process.jaxb.unitinfo.impl.OrganizationalUnitImpl
java.lang.ClassCastException: com.iwise.process.jaxb.unitinfo.impl.OrganizationalUnitImpl
at com.iwise.process.test.TestClient.saveParticipant(TestClient.java:58)
at com.iwise.process.test.TestClient.main(TestClient.java:33)
TIA, Claire

What was wrong with your package structure? I'm running into a similar problem where one XML doc/schema combo parses great, but another throws the java.lang.ClassCastException.

Install JAXB and JAXP only

Hi,
We want to use the funtion of JAXB and JAXP
but do not want to use the whole java web service
Can the JAXB and JAXP work separately on JDK1.2/JDK1.3.1
Jacinle

The Jaxb directory in jwsdp-1.2 dir has the JAXB implementation.
The Jaxp directory in jwsdp-1.2 dir has the JAXP implementation.

Does BEA WLS 7.0 or 8.1 support JAXB and JAXR?

Hello
Does BEA WLS 7.0 or 8.1 support JAXB and JAXR?
Thanks

Hi a,
The short answer is no B or R yet, but stay tuned.
The somewhat longer story is that we are very much engaged with this
emerging binding standard to be used inconjuction with and beyond the
built-in types specified in JAX-RPC 1.1, it should be seen as a
compelling story for J2EE if JAXB could be used as a mechanism for
extending type mapping and offer a vendor neutral way to deal with user
defined types and to easily utilize user types that are developed for
XML applications in web services.
Concerning JAXR, I've experimented with SUN's RI using our UDDI server
and it works fine. As to the arguable merits of JAXR, all I can say is
that it is part of J2EE 1.4.
HTHs,

Apache axis, JAX-RPC, JAXR, JAXM, JAX-WS, JAXB, and Metro

Are all of the following the different APIs for creating web service applicaton?
Apache axis,
JAX-RPC,
JAXR,
JAXM,
JAX-WS,
JAXB, and
Metro
--If so, which one(s) are most widely used?
--If not, what are the differences among them?
Thanks
Scott

I think your are looking for a full web services framework.
Apache axis --> Is a WS framework. implements jax-rpc. Provides some features on its own
JAX-RPC --> Is a WS framework specification. Your application servers/axis implement this.
JAXR --> not an web-service api, rather a web-service registry access api
JAXM --> Is an api for xml messaging. Your framework provider may use this.
JAX-WS --> Is jax-rpc 2.0. Your application server provider will give implementation for this. Otherwise you can use xfire/metro as the implementation. Chose this over jax-rpc.
JAXB, --> Is used for xml-java binding. Jax-ws uses this. But not specific to jax-ws..
Metro --> Reference implementation for jax-ws.
All in all jax-rpc, jax-ws and axis2 are three options. go for jax-ws if you do not have any other constraints.As for selcting implementation of jax-ws, if you are working on an app-server (and not on a simple servlet container or without a server), server vendor will provide that. Otherwise look for xfire or metro.

WSAD 5, xerces, datasource and classcastexception issue

I am running into an issue trying to run my code once I upgraded from WDAD 5.0 to WSAD 5.01. I am getting the error below when I try and connect to my DataSource. This all was working fine before I upgraded. It looks like an issue with the xerces.jar file because if I take out the JAXP stuff in the xerces.jar file I work fine. But I need the JAXP stuff because I am doing messaging. Anyone have any ideas?

JAXB and JDK 1.3.1.x

Where can I get a download of the JAXB stuff to work with JDK 1.3.1.x?
I downloaded the latest WSDP 1.2 and it works great, but it requires JDK 1.4.x. Unfortunately, our Production envrionment is moving to Weblogic Server 7.x which doesn't support JDK 1.4.x.
Thanks for your help.

Well. I finall found the archive url. It's http://java.sun.com/webservices/archive.html.

Marshalling with JaxB and HyperJaxb

Hi guys,
Can you guys help me based on what is happening below? What I don't
understand is that HyperJaxB inserts the data fine. I only have
this problem when pulling it out.
In the schema, the element type is stated with minoccurs=0. It is true, that sometimes the data may or may not be present. I have also added nillable="true" to the XSD, but this doesn't seem to make a difference.
Doing some more research on the problem, I discovered that it is
because some of the XML types in my schema are optional. They occur
in some documents and not others of the same type.
Thanks,
I am getting a null pointer exception as shown below:

JAXB does not support xs:any

PROBLEMS JAXB and XML-schema

Hello,
I think my problem is not directly related to JAXB but to my understanding of schema-files.
I defined a schema like that:
<xsd:complexType name="BSR">
<xsd:sequence>
<xsd:element name="VERB" type="VERB"/>
<xsd:element name="NOUN" type="NOUN"/>
<xsd:element name="REVISION" type="REVISION"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="VERB">
<xsd:simpleContent>
<xsd:extension base="xsd:string">
<xsd:attribute name="value" fixed="ACKNOWLEDGE"/>
</xsd:extension>
</xsd:simpleContent>
</xsd:complexType>
<xsd:complexType name="NOUN">
<xsd:simpleContent>
<xsd:extension base="xsd:string">
<xsd:attribute name="value" fixed="PO"/>
</xsd:extension>
</xsd:simpleContent>
</xsd:complexType>
<xsd:complexType name="REVISION">
<xsd:simpleContent>
<xsd:extension base="xsd:string">
<xsd:attribute name="value" fixed="003"/>
</xsd:extension>
</xsd:simpleContent>
</xsd:complexType>
When I tried to compile that schema via JAXB I got the following error:
[ERROR] A property with the same name "value" is generated from more than one schema component line 31 of ACKNOWLEDGE_PO_003.xsd
[ERROR] (Relevant to above error) another one is generated from this schema component. line 14 of datatypes.xsd
[...] and so on!
How do I manage to use that attribute "value" in several elements???
Is there a possibility to declare the attribute once an refer to it, like to an type?
Please help, I could not find anythig in docu.
thanX chris

hallo again,
i tried that, but the point is, if i remove the declaration of the attribute called "value" it works fine.
<xsd:element name="BSR">
          <xsd:complexType>
               <xsd:sequence>
                    <xsd:element ref="VERB"/>
                    <xsd:element ref="NOUN"/>
                    <xsd:element ref="REVISION"/>
               </xsd:sequence>
          </xsd:complexType>
     </xsd:element>
     <xsd:element name="VERB">
          <xsd:complexType>
               <xsd:simpleContent>
                    <xsd:extension base="xsd:string">
                    </xsd:extension>
               </xsd:simpleContent>
          </xsd:complexType>
     </xsd:element>
     <xsd:element name="NOUN">
          <xsd:complexType>
               <xsd:simpleContent>
                    <xsd:extension base="xsd:string">
                    </xsd:extension>
               </xsd:simpleContent>
          </xsd:complexType>
     </xsd:element>
     <xsd:element name="REVISION">
          <xsd:complexType>
               <xsd:simpleContent>
                    <xsd:extension base="xsd:string">
                    </xsd:extension>
               </xsd:simpleContent>
          </xsd:complexType>
     </xsd:element>
I can compile it that way! but i need these attributes called "value" as you see them above....
so i think i worked out, that the problem is not in the "BSR"-tag, but the 3-times occurrence of the attribute "value".

XML (un)marshalling with JAXB and "any" blocks

I have 2 very simple XSD schema's.
SchemaA.xsd:
[request]-------[element_A] is xs:string
|__(ANY)
SchemaB.xsd:
[body]--------[element_B] is xs:string
The any block says that there can follow any type of xml after the element_a.
In the xsd it is coded as: <xs:any />
I compiled both schema's with jaxb, using this command line:
xjc SchemaA.xsd -p test.request
xjc SchemaB.xsd -p test.body -use-runtime test.request.impl.runtime
I created the following code :
test.request.ObjectFactory of1 = new test.request.ObjectFactory();
test.body.ObjectFactory of2 = new test.body.ObjectFactory();
Request r = of1.createRequest();
r.setElementA("testing, element one");
Body b = of2.createBody();
b.setElementB("testing, element two");
r.setAny(b);
Marshaller m = of1.createMarshaller();
m.marshal(r,System.out);
And the result is what I expected:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<request><element_a>testing, element one</element_a><body><element_b>testing, element two</element_b></body></request>
JAXB added the xml from the second schema to the first.
Ok, so far so good. Now I'm trying to do it the other way around, I want to unmarshall that XML to objects again:
String xml <- contains the outputted xml from the marshall (as pasted a few lines above)
Unmarshaller um = of1.createUnmarshaller();
Request r2 = (Request)um.unmarshal(new ByteArrayInputStream(xml.getBytes()));
System.err.println(r2.getElementA());
System.err.println(r2.getAny());
The output:
testing, element one
null
now, the first message is good. The second is not however...why is the "getAny" null ? I can't figure this one out. In the best possible case it should return an object that can be cast to "Body" .
In the worst case it should just return the "<Body> ...." xml as string. But not null ...
Any help on this is appreciated !

Jaxb and xsd problem

Hi,
I am trying to compile a set of generated jaxb classes from the xsd defined below. During compilation I get an error stating "Nested type GuestCountType hides an enclosing type". Does anyone see a problem with my xsd file. Appreciate any help with this problem

     <xs:complexType name="GuestCountType">
          <xs:sequence>
               <xs:element name="GuestCount" maxOccurs="99">
                    <xs:complexType>
                         <xs:attributeGroup ref="GuestCountGroup"/>
                    </xs:complexType>
               </xs:element>
          </xs:sequence>

     </xs:complexType>
     <xs:complexType name="RoomStayCandidateType">
          <xs:sequence>
               <xs:element name="GuestCounts" type="GuestCountType" minOccurs="0"/>
          </xs:sequence>
     </xs:complexType>
     <xs:attributeGroup name="GuestCountGroup"/>
</xs:schema>

Refer to section
E.2 Not Required XML Schema
concepts
"A JAXB implementation is not required to support the following XML Schema
concepts for this version of the specification. A JAXB implementation may
choose to support these features in an implementation dependent manner."
E.2.2 Not supported while manipulating the XML
content
Schema component: wildcard
(any)
how can i know if an xml element with xsi:nil="true" (unmarshal)
and set xsi:nil="true" for an element (marshal) ?
According to the JAXB 1.0 specification:
If {nillable} is "true", the methods setNil() and isNil() are
generated.

Can anybody throw some light on it?
Because, it's urgent for my project.
I would appreciate any kind of help in this regard.
Thanks & Regards,

Hello Anilkumar,
Sorry for delay in reply as I was on out of work and didn't get chance to check the SDN forums.
I was able to do it in latest version sneak preview 11.
I think the problem with the version.

JAXB and JDK 1.1

Hi,
is it possible to use JAXB with JDK 1.1?
Is the source code available to change the collection imports?
Thanks
Guenther

Sorry, but the List class is in java.util since 1.2.
I have tried to use it with JDK 1.2.2, and it fails because the RI try to use some classes from the sun JDK (com.sun... classes) that are not yet there in the JDK 1.2.2. (Or that are different).
The same occurs with JDK 1.3.0.
So even if you don't take into account the problem mentionned by jlongmsn, the RI will not work with JDK 1.1.

Servlets and Workspaces (AND ClassCastExceptions)

          I have a similiar situation but am not getting a ClassCastException but rather a
          NullPointerException when I try
          to use a contained object in my stored object.
          I do this in the server:
          WorkspaceServicesDef workspaceServices = services.workspace();
          WorkspaceDef defaultWS = workspaceServices.getWorkspace();
          WorkspaceDef dataWS = defaultWS.getWorkspace("DATA_WORKSPACE",
          WorkspaceDef.CREATE,
          WorkspaceDef.SCOPE_SERVER);
          dataWS.store(cMSKey, ms);
          and this in the JSP page:
          // Get the default T3Client Workspace
          WorkspaceDef defaultWS = t3.services.workspace().getWorkspace();
          // Attach to the system subWorkspace already created
          WorkspaceDef myDataWS = defaultWS.getWorkspace("DATA_WORKSPACE",
          WorkspaceDef.ATTACH,
          WorkspaceDef.SCOPE_SERVER);
          MimicServer ms = (MimicServer) myDataWS.fetch("MimicServer");
          Questions:
          1)Must I make the Object I want to store in the WorkSpace Serializable?? The
          Documentation says it can just be
          a Java Object??
          2) In my JSP page I get a good Object reference, but its contents are null
          (Probably because I didn't implement write() and read()).
          Thanks,

Serialization and ClassCastException

hi all,
I have a a class like this:
import java.io.Serializable;
import java.util.ArrayList;
public class Fact implements Serializable {
     private String name;
     private ArrayList al=new ArrayList();
     public Fact(String _name) {
          name=_name;
          al.add("Pippo");
          al.add("Pluto");
          al.add("Papero");
     public String getName() {
          return name;
     public ArrayList getList() {
          return al;
and I want to serialize objects of it in a mySQL database table. the table has two field: 'name', a varchar(20) used as a key and 'object', a blob field to store Java objects.
this is my code to put object in the table (it seems to work fine):
public boolean putFact(Fact fact) { // inserts a new fact in the db
          Fact result=null;
          try {
               PreparedStatement pstmt=conn.prepareStatement("INSERT INTO facts VALUES (?, ?)");
               pstmt.setString(1, fact.getName());
               pstmt.setObject(2, fact);
               pstmt.executeUpdate();
               pstmt.close();
          } catch (SQLException ex) {
               System.out.println(ex.toString());
               return false;
          return true;
this code musts get an object from the table:
     public Fact getFact(String factName) {
          Fact result=null;
          try {
               Statement stmt=conn.createStatement();
               ResultSet rs=stmt.executeQuery("SELECT object FROM facts WHERE name='"+factName+"'");
               while (rs.next()) {
                    result=(Fact)rs.getObject(1);
               rs.close();
          stmt.close();
          } catch (SQLException ex) {
               System.out.println(ex.toString());
               return null;
     return result;
on the 7th line of the getFact method I have a ClassCastException: why?
in addition, if I remove the ArrayList element from the Fact class, my code works fine.
any help?
thanks a lot. :)

first of all, thanks for your support, sylviae. :)
well, I used your syntax
(System.err.println(anObject.getClass());) and the
result is "class Fact": so, the serialization process
seems to be right.
then, I tried to change the field from BLOB to
MEDIUMBLOB type, and now it works! so, I suppose that
the BLOB type was not able to manage a Fact object.That doesn't really make much sense. If in the revised code you were getting the exception on the line that casts anObject to be a Fact object, then I'd start to wonder about ClassLoader issues. Still, given that you've got it working, you're probably not concerrned about the exact cause.

in the end, can you suggest me a way to generate SQL
statements, if mine has the error you said?Use the prepareStatement mechanism as you did for the insert statement, and associate the value with the "?" parameter. I know this looks more clumsy, and is certainly more code, but it is much safer. It's also capable of a more effecient execution because the underlying implementation can note that it's already parsed the statement and avoid having to do it again.
Sylvia.
