JAXB -Binding Schema

What entries should you make in the binding schema for:
<rate year="2001">7.00</rate>
so that it constructs a class rate with a field "content" as a double and a field year as an int?

same questions:
in DTD defines
<!ELEMENT SERVICETYPE     (#PCDATA)>
<!ATTLIST SERVICETYPE
     type           CDATA #REQUIRED
     anon           CDATA #REQUIRED>
how should I define the element SERVICETYPE in my binding Schema?

JAXB binding schema type conversions

If your DTD contains something like this:
<!ELEMENT chicken (egg+)>
then JAXB gives you a Chicken class with a method that returns a List of Egg objects.
How can I specify in the binding schema that this collection should be a Hashtable (or other type of collection), not the default List? I think I probably have to write some sort of conversion class, but what is the syntax and how do I get it into my binding schema?

Hi you can use the <option> tag at the top-level of your binding schema definition. You can define the default collection type of to be used e.g.
<options default-reference-collection-type="array"/>
Or you can use the collection attribute of most element bindings e.g.
<choice property="entries" collection="array"/>
But only arrays and lists are supported. If you want a different collection type, then you will have to subclass the generated classes and use the Collections class and the collection classes to convert between different collection types.
Hope this helps.

JAXB binding schema problem

hi friends,
i didn't get implementation classes for xsd during the binding schema.i insatlled Jwsdp2.0and j2sdk1.5.Is any give me me an idea

Hi
Go through the sun website for doing so. This would give you a clue as to how to.

Can't create a JAXB binding for ejb-jar.xml using xjc

Hi all,
I have been trying to build a JAXB binding for EJB deployment descriptors, mainly because I have to update a hand-cranked ejb-jar.xml file on the fly with some additions that have come from a code generator.
I have tried to use
xjc ejb-jar_2_1.xsd j2ee_1_4.xsd ejb-jar_2_1.xsd
xjc on the schema definitions I found at http://java.sun.com/xml/ns/j2ee/ but I can't get it to work. It produces reams of errors, see below for a short extract.
Of course, someone could put me out of my misery and tell me where to find a binding that someone else has done. I can't be the first chimp on the planet that has wanted to do this!
Any help much appreciated.

Troubleshoot JAXB "chameleon schema" Errors

I am trying to use xjc from JAXB 2.1 to generate Java code for the HL7 CDA R2 format. Unfortunately, there appears to be errors in XML Schema files and so xjc fails with this exception.
The XML Schema files can be downloaded from http://xreg2.nist.gov/cda-validation/downloads/archives/HITSP_C37_TestPackage_03Jan_2008.zip.There are total 7 Schema files, and their names are: LabCDA.xsd, LabPOCD_MT000040.xsd, TF_Vol3_Lab.xsd, datatypes.xsd, datatypes-base.xsd, NarrativeBlock.xsd and voc.xsd. The relationship of the Schema files are complex: LabCDA.xsd is the top level Schema and includes LabPOCD_MT000040.xsd; LabPOCD_MT000040.xsd incluedes datatypes.xsd, NarrativeBlock.xsd and voc.xsd and imports TF_Vol3_Lab.xsd; TF_Vol3_Lab.xsd incluedes datatypes.xsd; datatypes.xsd incluedes datatypes-base.xsd; datatypes-base.xsd includes voc.xsd; voc.xsd includes datatypes.xsd.

JAXB has extra rules that it uses to validate the schema. I believe this is for simplicity in the code generation side. For example, you can't have a maxOccurs="unbounded" element in an "all" complex element, it must be in a "sequence".
In this case (and hopefully all others) fixing the schema so that JAXB will accept it is not going to hurt anything. A length requirement is both a maxLength and a minLength.
There are some rules I don't appreciate that JAXB tacks on. For example, if you import another schema into your binding schema, and don't use every type specified in the imported schema, it will balk. Why? I can't think of a good reason. It really makes it a pain in the ass to create reusable custom XML types. I have to have a different schema for every type.

Jaxb -binding specific elements of schema to class

Is there a way to bind only specific elements from a schema to a class instead of binding everything in the schema. If yes, how do you specify this.

The <class> binding declaration customizes the binding of a schema element.
http://java.sun.com/xml/jaxb/users-guide/jaxb-custom.html#customdesc_class

JAXB - binding several schemas at once

If I have 4 schemas, each one including/chaining another (except the base schema of course). I want to bind all of them. I tried just puting all the schema names in the bind command but i get errors stating that 'class/interface with the same name is already in use'. If I do each individually I also get the same errors. How can I resolve this?

Actually more like this from the cmd prompt:
%JAXB_HOME%/bin/xjc.bat -p mypackage A.xsd B.xsd C.xsd D.xsd -d src
Its not that it doesn't work but that it produces naming conflict errors. I just found something on google that might help me out though. Thanks

Error in Jaxb binding for wsdl document

Hello
below is my wsdl and binding.xjb that I am using. I want to rename the " <element name="getRelatedAssets">" name from 'getRelatedAssets' to 'getRelatedAssetsX'.

Can anyone help me out in finding what wrong I am doing.
I appreciate.

Well, As I mentioned There is an element named 'getRelatedAssets' and I want to rename it to some other name like 'getRelatedAssetsXXXXX' which would not be in Schema using jax binding.
Note. When I manually change the name to 'getRelatedAssetsXXXXX' in WSDL, it works. but I want to make it using jaxbinding.
Anyways,Thanks for the reply.

Jaxb bind to custom class

Hi,
i have a wsdl with such schema: complextype person with elements COLBOBPPHONE, COLBOBPPHONE and COLBOBPEMAIL. wsimport generates than class Person and getters/setters for this elements. I'd like a custom binding, than makes one member in Person named communications. In communications i'd have getters and setters for COLBOBPPHONE, COLBOBPPHONEand COLBOBPEMAIL. Than i would access it by person.getCommunications().getCOLBOBPPHONE(). So i try like this, i created a new complextype:
<complexType name="Communications">
<all>
<element name="telephones" type="ns:COLBOBPPHONE" minOccurs="1"
maxOccurs="1" nillable="true" />
<element name="faxes" type="ns:COLBOBPPHONE" minOccurs="1"
maxOccurs="1" nillable="true" />
<element name="emails" type="ns:COLBOBPEMAIL" minOccurs="1"
maxOccurs="1" nillable="true" />
</all>
</complexType>How to i say in jaxb custom bindings that the elements COLBOBPPHONE, COLBOBPPHONEand COLBOBPEMAIL should be bind to property communications which is class Communications? Is this even possible with jaxb? Maybe i have to use jixb or something else?
for better understanding, is the structure mapping that description follows possible also with jaxb? [jibx structure mapping|http://jibx.sourceforge.net/binding/tutorial/binding-structures.html]

yes. check getter and setter functions.

JAXB binding list of doubles

Hi, I have a problem in binding elements containing a list of doubles. The elements may occur many times. In the generated code, doubles from different elements are returned in the same list. Is there any way to force the creation of a new java type, so that doubles from different elements can be accesed separately?
Example:
XSD:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
     elementFormDefault="qualified">
     <xsd:element name="main">
          <xsd:complexType>
               <xsd:sequence>
                    <xsd:element name="foo" type="foo"/>
               </xsd:sequence>
          </xsd:complexType>
     </xsd:element>
     <xsd:complexType name="foo">
          <xsd:sequence>
               <xsd:element name="bar" type="doubleArray" minOccurs="1" maxOccurs="unbounded"/>
          </xsd:sequence>
     </xsd:complexType>
     <xsd:simpleType name="doubleArray">
          <xsd:list itemType="xsd:double"/>
     </xsd:simpleType>
</xsd:schema>
XML
<?xml version="1.0" encoding="UTF-8"?>
<main xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="forum.xsd">
     <foo>
          <bar>1 2 3</bar>
          <bar>4 5 6</bar>
          <bar>7 8 9</bar>
     </foo>
</main>Generated code:
     * Objects of the following type(s) are allowed in the list
     * double
    java.util.List getBar();Method getBar returns a list containing all the doubles from all the bar elements, instead of returning a list of objects of type Bar, where each object at its turn contains a list of doubles.
Thank you

I certainly wouldn't start writing a JAXB clone just based on what you posted here.

JAXB binding for Boolean

Hi,
I'm using xml and JMS to query a remote system.
One of the values in the remote system that I am interested in is a boolean value. I do not know this field is defaulted in the remote system so I want to use a Boolean object to represent it. I.e I want it to be null is no value is available in the remote system.
Could any of you give me a quick run down on how to go abount doing this or point me to a tutorial.
Is there another way of doing what I am trying to do?
Appreciate any help.
Cheers,
Nim

Hi James,
Yup, I'm trying to process the xml returned by the remote system.
The Boolean is an element and not an attribute:
The schema i am using is shown below:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="accounts" type="AccountsType"/>
<xsd:complexType name="AccountsType">
<xsd:sequence>
<xsd:element name="account" type="Account" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="Account">
<xsd:sequence>
<xsd:element name="accountId" type="xsd:string"/>
<xsd:element name="customerId" type="xsd:string"/>
<xsd:element name="totalAmountOwing" type="xsd:decimal"/>
<xsd:element name="amountOwing" type="xsd:decimal"/>
<xsd:element name="totalArrears" type="xsd:decimal"/>
<xsd:element name="paymentExtensionCount" type="xsd:integer"/>
<xsd:element name="paymentHistoryIndicator" type="xsd:string"/>
<xsd:element name="payDate" type="xsd:date"/>
<xsd:element name="directDebitSchedule" type="xsd:boolean"/>
<xsd:element name="easyPaySchedule" type="xsd:boolean"/>
<xsd:element name="billIssueDate" type="xsd:date"/>
<xsd:element name="arrearsDebtAge" type="xsd:integer"/>
<xsd:element name="sourceSystemId" type="xsd:string"/>
<xsd:element name="readFrequency" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
I have access to change the schema. I tried making the boolean an attribute as shown below:
<xsd:element name="easyPaySchedule">
<xsd:complexType>
<xsd:sequence/>
<xsd:attribute name="value" type="xs:boolean"/>
</xsd:complexType>
</xsd:element>
but I could not see the isSetMethod in the jaxb account implementation file.
I changed it back and added minOccurs="0":
<xsd:element name="easyPaySchedule" type="xsd:boolean" minOccurs="0" maxOccurs="1"/>
and started seeing the isSetMethod in the jaxb account implementation class but not the generated account interface.
Next, I used the xjb file below:
<jxb:bindings version="1.0"
xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<jxb:bindings schemaLocation="accounts.xsd" node="/xsd:schema">
<jxb:bindings node="//xsd:complexType[@name='Account']">
<jxb:bindings node=".//xsd:element[@name='easyPaySchedule']">
<jxb:property generateIsSetMethod="true"/>
</jxb:bindings>
</jxb:bindings> 
</jxb:bindings> 
</jxb:bindings>
and I started seeing the isSet methods in the generated Account interface.
I thought I was in the clear but when I try and run it with the xml below:
<account>
<accountId>11111111111</accountId>
<customerId>2222222</customerId>
<totalAmountOwing>123</totalAmountOwing>
<amountOwing>12</amountOwing>
<totalArrears>0</totalArrears>
<paymentExtensionCount>1</paymentExtensionCount>
<paymentHistoryIndicator>110111001111</paymentHistoryIndicator>
<payDate>2004-10-08+10:00</payDate>
<directDebitSchedule>false</directDebitSchedule>
<easyPaySchedule></easyPaySchedule> <<<<<<------ blank instead of false/true
<billIssueDate>2003-10-08+10:00</billIssueDate>
<arrearsDebtAge>0</arrearsDebtAge>
<sourceSystemId>cise</sourceSystemId>
<readFrequency>Q</readFrequency>
</account>
I start to get the following exception:
javax.xml.bind.UnmarshalException: Unexpected text ""
- with linked exception:
[java.lang.NullPointerException]
Any ideas as to whats going on?

How to bind schema form data to existing objects?

I imported an existing PDF as my template and it make all the text, check boxes and text fields into objects - Great!
But now when I add a schema with my DB data field names I am unsure how to turn the existing objects on the form to the schema fields!!
Can anyone help?

Open the DataView where your schema is visually represented and simply drag and drop the schema item onto the object that you want to bind it to. If the bind is successful a little icon will appear in the DataView beside the node.
If you select on object in the form and click on the Binding tab, you will see an expression representing what you are bound to. You can also use the icon there to navigate to the appropriate node in the schema.

XML JAXB Binding issue

Hi All
Im using Webservices in which i need to Bind my XML to Java objects and reverse. Im trying to use JAXB (1.0) Ref Imp from SUN as binding framework. The problem which im facing is that for elements like:
<xs:element name="inputRequests">
<xs:complexType>
<xs:sequence>
<xs:element maxOccurs="unbounded" name="inputData" type="data" />
</xs:sequence>
</xs:complexType>
</xs:element>
JAXB genetrates:
1. InputRequest - Interface
2. InputRequestImpl - Class
3. InputRequestType - Interface
4. InputRequestTypeImpl - Class
in InputRequestType it has generated a getter method
public java.util.List getInputData();
but no setter method for 'inputData'.
Can any one help on that how we can set a sequence element in JAXB classes. I even used JAXB 2.0, but faced same issue...
No Setter for a LIST :-(((

That method, getInputData() is returning a reference to a List Object that is already instantiated. Once you retrieve the reference, you can invoke all the methods in the List interface, but if there is a way to reassign the reference to refer to a different list, I'm not aware of one.
I believe that limitation is necessary my the nature of JAXB. A JAXB Object, in your case a List, is guaranteed to be marshaled and unmarshaled to XML, if you redefine the reference to some arbitrary List, how could JAXB guarantee its functionality?
I may be way off base here, I'm no JAXB expert by any means.
Rather than redefining the reference to a different List, you have to manipulate the List
...getInputData().clear();
...getInputData().addAll(myRequestList);Right?
