Problems generating classes with JAXB

Does anyone know where there might be a list of known problems with generating classes from an xsd with JAXB? I have a very deep and pretty complicated xsd, and it seems some elements get generated correctly and some don't. It's very hard to find any pattern of why. Is there a limit to the number of levels deep it will go?

How to use JAXB generated classes with SOAP

hello,
I have a library of JAXB generated classes for my web service. There is a Java class for each web method defined in my schema. For example, my getLocation method is mapped to GetLocation.class.
However my web service is SOAP based, so I am having to manually strip off the SOAP elements to be able to unmarshall the getLocation xml to a GetLocation class.
I am noticing a disconnect between JAXB and other Java SOAP and RPC libraries. Does anyone know how to create a JAXB class for SOAP Envelopes and Bodys? Does anyone have any ideas how to incorporate the existing Java web service libraries with JAXB?
Thanks in advance.

Have you found a method to integrate SAAJ and JAXB? Or
is better to use SAAJ only ?If I had to choose I'd go with SAAJ. It seems to me that's theoretically possible to use JAXB classes with SAAJ but I imagine if it is possible it would be a big pain in the ass.

Can't generate setters for array or collection classes with JAXB

I am trying to use JAXB to generate the required setters for Spring beans. Although according to the book Java & XML Data Binding
Chapter 3 page 42 by Brett McLaughlin it was possible with DTD's using
<?xml version="1.0"?>
<xml-java-binding-schema version="1.0-ea">
<options package="javajaxb.generated.movies" default-reference-collection-type="array" />
<element name="movies" type="class" root="true"/>
</xml-java-binding-schema>
to generate an array as in
public Movie[] getMovie( ) {
// implementation
public void setMovie(Movie[] _Movie) {
it doesn't look like that capability exists with JAXB 2.0 and XML Schemas. In their wisdom they just generate getters on Lists and tell you:
<p>
* This accessor method returns a reference to the live list,
* not a snapshot. Therefore any modification you make to the
* returned list will be present inside the JAXB object.
* This is why there is not a <CODE>set</CODE> method for the filingForm property.
* <p>
* For example, to add a new item, do as follows:
* <pre>
* getFilingForm().add(newItem);
* </pre>
Of course this doesn't work for Spring injection where setters are needed.
Does anyone know different or is there a way of getting around this ?
I've tried constructor injection in Spring but it's not as convenient and involves extensive coding of generated code (not nice).

Oh I found it on this post

collectionType="indexed" in the globalBindings-tag
it works in schema internal global bindings as well

How to extend/ replace generated classes from JAXB

Hello Experts,
In our application (Which uses Java Webdynpro as the UI and RFCs for the backend access- an R/3 System), there is a need to construct an XML file (from the data entered by the user) which will be later accepted by the backend system. Now to avoid manual creation of the XML document, what we did is that we created an XSD file based on the back end structure (This XSD contains definition for all the possible fields and structures in the back end).
Then we used the JAXB implementation to automatically create Java Objects from the XSD file. We populate this JAXB generated Java objects and then use the Serialization framework to serialize them into an XML file.
This all works well, provided that the structure of the back end system does not change, but unfortunately it can, customer can add additional attributes to the existing structures (They do not create new structures, just add new attributes to it so I do not need to create new Java Object classes at runtime, I need only to add attributes to them). If they do so, the XSD and corresponding Java Objects (which are shipped as part of the source code) do not remain valid anymore as the automatically generated Objects (which correspond to the structures in the back end) would not have the definition of the newly added attributes.
Can anyone please suggest how to overcome this limitation with JAXB.
The needed functionality is that somehow I should be able to add fields (corresponding to the customer added attributes) to the automatically created Java objects and thus pass the data in the additional attribute to the backend. (Please note that at runtime using an RFC, I can find out the current structure of the backend but the structure at the Webdynpro end (set of Java objects generated from the JAXB) is static and is a part of the code).
Any comments/suggestions could be of great help.
Thanks
Amit Kapoor

You cannot do that. TheJAVA language does not allow a class to "extend" more than one upper class.
Typically, the solution is to modify your architecture a little bit. Just use the "has a" relationship instead of "is a". That means something like that:public class MyFraisMessage
extends MyOtherClass
private FraisMessage message;
etc...You write an extension "MyFraisMessage" of your upper class "MyOtherClass", which has the JAXB generated object as an attribute. This structure is often useful, when you think you would need multiple inheritance.

Problem generating Key with keytool command

Hi Everyone;
I'm having problems generating a key.
Here's my output.
C:\>keytool -genkey -alias learningIdeas -keysize 1024 -validity 365 -keyalg RSA
Enter keystore password: changeit
keytool error: java.io.IOException: Keystore was tampered with, or password was incorrect
note i already did something with the keystore such that i have generated a key and placed this in server.xml
<Connector className="org.apache.tomcat.service.PoolTcpConnector">
<Parameter name="handler" value="org.apache.tomcat.service.http.HttpConnectionHandler"/>
<Parameter name="port" value="8443"/>
<Parameter name="socketFactory" value="org.apache.tomcat.net.SSLSocketFactory" />
     <Parameter name="keystore" value="C:/stephen" />
     <Parameter name="keypass" value="changeit"/>
     <Parameter name="clientAuth" value="false"/>
</Connector>
any ideas on what I can do to generate this key?

I have almost resolved this problem. I'm at the last step and getting an error message when trying to import the certificate that I received from verisign into my keystore.
here's my error.
C:\>keytool -import -alias mycompanyname123 -keystore STEPHEN4 -file mycompanyname.cer
Enter keystore password: changeit
keytool error: java.security.cert.CertificateException: Unsupported encoding
but when I double click on this file mycompanyname.cer (which is exactly what I received from verisign, up comes the appropriate certificate
i was able to succesfully able to install it into the microsoft browser and i see it correctly represented and displayed in the certificates section for OTHER PEOPLE.
But I think i have to successfully import it into the keystore for it to work properly right when I start up the tomcaat app is that correct?
any ideas?

Problem generating index with 2th level in cs4

Windows XP sp 3 - Indesign CS4 601
When generating an index with a 1st and a 2th level, in the 2th level the entry of the 1st entry is always repeated.
E.g. the index should look as this:
text     75
     capitalized     76
     import     78
word     105
     language     108
     meaning     109
But actually the index looks as this:
text     75
     textcapitalized     76
     textimport     78
word     105
     wordlanguage     108
     wordmeaning     109
Is this a bug, or is there a solution for it?
Thanks for your help!

Oops!
Just tested the script.
I run it, and I get the script alert 'All Done' at the end.
But nothing happens.
This is what I do:
- I generate the index.
- I select the index with the text tool (select all or just put the textcursor somewhere in the index makes no difference).
- I run the script
- I get the message 'all done', but there is no difference. The problem persists.
Any other ideas?
Thanks anyway.

Marshalling third party classes with JAXB

I put together a test case similar to what is illustrated at:
[https://jaxb.dev.java.net/guide/XML_layout_and_in_memory_data_layout.html#Using_XmlJavaTypeAdapter_for_element_attribute_values]
and here:
[http://weblogs.java.net/blog/kohsuke/archive/2005/09/using_jaxb_20s.html]
I declared a Color object, defined a ColorAdapter, and declared the @XmlJavaTypeAdapter to the package. Alas, it isn't getting called... If you consider the following sample code:
JAXBContext jc = JAXBContext.newInstance(Color.class);
// Note that a dump of the context confirms that com.acme.Color is listed!
//System.out.println("JAXBContext: " + jc.toString());
Marshaller m = jc.createMarshaller();
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
Color color = Color.RED;
// Case 1: The following line works, but it does NOT call the ColorAdapter...
m.marshal( new JAXBElement( new QName("", "rootTag"), Color.class, color ), System.out);
// Case 2: This fails...
m.marshal(color, System.out);Case 1 "works" (doesn't error), but the output clearly shows that the ColorAdapter is not getting called.
Case 2 throws a javax.xml.bind.MarshalException exception:

Reusing JAXB generated classes for XSDs included in other XSDs

Hi,
I use xsds with jaxb in a number of related projects. To avoid duplication I've factored out commonly used elements into their own xsd in a separate project. I then include these in the xsds that need them.
I generate classes with jaxb for each project. I'm now trying to get jaxb so far as to reuse the already generated classes for the common elements.
For example: I have a general xsd Person.xsd for which I generate classes in common.xsd. I have another xsd Project.xsd that includes a reference to the Person element. When i let jaxb generate classes for Projects.xsd, it will also generate a project.xsd.PersonType and so on.
Is there any way to tell JAXB to use the existing classes? I've played around with the <jxb:javaType> bindings, but I can't get it to work yet. It gives me a "bindings not used" warning and doesn't compile. Also, if this is in fact the way to go, what do I specify as the parseMethod and printMethod attributes for the javaType element?
Thx for any help

JAXB questions should be better directed to the users list of http://jaxb.dev.java.net/
you should subscribe to the 'users' mailing list, then post a question there.
Thank you!

Namespace issue with oracg generated classes

Hi,
I'm having problems generating classes with oracg from the Java Xdk from an XML schema. All classes are generated, but do not compile. In some sources (mostly in the type classes) "public void addSomething(null.Something theSomething)" is generated as the method declaration, and that doesn't compile. When I add a targetnamespace to the xsd file, the generated sources compile (the 'null.' is replaced with 'myPackage.', but when I generate an XML document, I contains a namespace reference (ns1) like this:
<ns1:Note xmlns:ns1 = "http://www.somewhere.org">
<ns1:Form>
<ns1:Reference>
<ns1:ReferenceNbr>1</ns1:ReferenceNbr>
<ns1:ReferenceType>1</ns1:ReferenceType>
</ns1:Reference>
</ns1:Form>
</ns1:Note>
What I want is this:
<Note>
<Form>
<Reference>
<ReferenceNbr>1<ReferenceNbr>
<ReferenceType>1<ReferenceType>
</Reference>
</Form>
</Note>
How can I get this result ?
Kind regards.

Did you try adding the the XmlSeeAlso annotation to the webservice
@XmlSeeAlso({<package.name>.AccountIC.class})
This will add the schema for the data type (AccountIC) to the WSDL.
Hope this helps.

Automatic Generation of classes with required attribute names

The problem is the attributes I am to use are named differently as that found in

n mapped them using the Castor mapping with the attributes.
I was wondering how should I achieve --"automatic generation of classes" with th

Specifying package structure and inheritance for jaxb generated classes ??

Friends,
Now I am tuned up with the sweet JAXB utility...
I need answers to this..
1. How do I specify a package structure in my generated java files?
2. How do I specify inheritance heirarchy to my generated java files ?
I assume, there must be some way of doing this, without opening the actuall source.
any ideas ??
Thanks
Rakesh

how about inheritance heirarchy ? What if i plan to include theses generated classes in my inheritance heirarchy ?
Bhakti, any idea what is the final version release date ? I desperately need answer to this.
Thanks
Rakesh
