JAXB & DTD

Hi there
In order to develop an XML-based applikationmodule I wanted to use JAXB.
Actually we only hav a DTD that describes our XML-documents.
Now my question is: Is there a way to use JAXB with DTD instaead of schema, or does someone know a tool for converting DTD to an equivalent schema?
Thanks very much
danwan

OK I found out!
see: http://www.xml.com/pub/a/2002/08/28/validation.html

JAXB DTD and XJS element specification

I have a DTD with the following element declaration:
<!ELEMENT PersonIdentifiers ((GvtNbr, (IdSateNbr, IdStateCd)?) | (IdStateNbr, IdStateCd))>
GvtNbr, IdStateNbr, and IdStateCd are all #PCDATA
How can I structure my XJS in order that I don't just have to call getContent() and then search for what I want?

Have you tried an interface, which would consist of an IDStateNbr and an IDStateCd?
the only problem with your setup and jaxb right now is that jaxb will choke on validation, if your optional element isn't present. hopefully, this bug will be fixed when the 1.0 version comes out, later this year...

DTD to java

i need to write a model class for a dtd file, that is, read a dtd and model it into fields in,say, a java object. Is there an easy way to do it?

Hi,
you might want to check JAXB ( [https://jaxb.dev.java.net/|https://jaxb.dev.java.net/] ), which supports XML schema, but also DTD. It is used to create Java classes from an XML schema or DTD, which also contain code to marshal or unmarshal an XML document to Java classes or vice versa.
JAXB (package javax.xml.bind) ist part of Java SE 6.0. In prior versions, it was shipped separately or as part of the web service tools.
Martin
PS: after reading your post a second time I see, that you do not want to create classes out of a DTD, but objects which contain a description of the classes! That's not the intention of JAXB.
However the developers of JAXB had to do the same when they wrote the JAXB DTD compiler. So perhaps you get some ideas if you look for the source code of the reference implementation of the JAXB compiler.

How to ignore DTD in xml files under JAXB?

hi,
I have a program that has to access files which declare they use a DTD that no longer exists on the web in that location.
we don't have the option to alter the xml files since they don't belong to us!
I've written an equivalent schema and its all working with the files that have correct DTD references.
Is there a way to tell the unmarshaller not to attempt to use the DTD that the documents declare?
thanks,
asjf

I've found that by opening a inputstream to the XML file and wrapping it to filter the DTD out altogether and passing that inputstream to JAXB does the trick.
this seems actually faster, since it doesn't go off on the net to look for the dtd!
is this not catered for already somewhere??
thanks,

Setting the DTD in the JAXB generated Java Classes

Hi All,
I have generated the Java Source file for a DTD using the xjc tool that comes with JAXB .
Now from the Class files i can unmarshall and get the XML file . But in the generated XML output file we don't have the <!DOCTYPE > Element which binds the XML to the DTD .
Is it possible to specify the DTD ? If so Where can we specify that .
Thanks for your help...
Sateesh

Parse the Dtd for a DOCUMENT_TYPE_NODE & create a <!DOCTYPE >element in the output xml.
PrintWriter pw=new PrintWriter();
if(node.getNodeType()==Node.DOCUMENT_TYPE_NODE){
DocumentType doctype = (DocumentType)node;
pw.print("<!DOCTYPE ");
pw.print(doctype.getName());
String publicId = doctype.getPublicId();
String systemId = doctype.getSystemId();
if (publicId != null) {
pw.print(" PUBLIC '");
pw.print(publicId);
pw.print("' '");
pw.print(systemId);
pw.print('\'');
else {
pw.print(" SYSTEM '");
pw.print(systemId);
pw.print('\'');
String internalSubset = doctype.getInternalSubset();
if (internalSubset != null) {
pw.println(" [");
pw.print(internalSubset);
pw.print(']');
pw.println('>');}

JAXB problem with DTD file

Hi All,
I just started to learn JAXB and I come to a point in which I need to run xjc on a dtd file and jxs file. The problem is that is gives me an ERROR :

Try adding dom4j.jar (http://www.dom4j.org/) to your classpath and compiling with the -dtd switch. E.g.:
xjc -dtd foo.dtd

JAXB is incorrectly handling the ? DTD sign.

When writing a DTD that has an element that can occur either one or zero times, I have used the ? sign. However, when such a JAXB object is validated, a NullPointerException is thrown if the element is not present. Either this is a bug or I am missing something obvious. Below you will find a snippet of my DTD. I am referring to the "dependency" element. Just wanted to clear it here first before I submit a bug report. Thanks in advance for all help.

<!ELEMENT question (text+,option*,dependency?) >

Oops, this is already reported as bug id 4497267. Didn't find it the first time I searched.

Dtd support for jaxb

i know the beta won't work with dtds. Is this feature gone for good from jaxb or just the beta? I read the FAQ http://java.sun.com/xml/jaxb/faq.html. and it seems like it says dtd is gone, but doesn't come out and clearly say so.

I have a requirement to implement with java and XML. I am quit new to XML.Can any of you pls help me.
I have a DTD file. I need to generate XML document from it using java code. I have to use DTD as a template to generate my XML document.
After going through WEB sites, I understtod that, we have to user Java API JAXB for my requirement. But I could not find JAXB.jar anywhere.
I need to know the following inforamtion ....
1. Is my understanding of using JAXB for my requirement is correct?
2. Where can I get JAXB.jar?
3. What are the steps to create XML document from a DTD in Java?

Can't import schemas in classpath when generating JAXB

I'm trying to create schemas that are used to provide basic components for more complex schemas, using the same design idea behind creating abstract Java classes and then extending them. I'm having trouble referring to classes in different modules, though. Below is the start of a schema that refers to a schema that is stored in another jar file:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
 targetNamespace="http://xml.kitfox.com/schema/tw/ts"
 elementFormDefault="qualified"
 xmlns:tns="http://xml.kitfox.com/schema/tw/ts"
 xmlns:cmn="http://xml.kitfox.com/schema/common">
 <xsd:import schemaLocation="/com/kitfox/common.xsd" namespace="http://xml.kitfox.com/schema/common"/>
 <xsd:complexType name="sourceType">
 <xsd:attribute name="uid" type="cmn:uidType"/>
 </xsd:complexType>I'm generating my JAXB with the following task:
 <target name="bind-preferences" depends="init">
 <taskdef name="xjc" classname="com.sun.tools.xjc.XJCTask">
 <classpath>
 <pathelement path="${javac.classpath}"/>
 </classpath>
 </taskdef>
 <xjc destdir="gen" extension="true" removeOldOutput="true">
 <schema dir="src">
 <include name="**/*.xsd"/>
 </schema>
 <produces dir="gen">
 <include name="**/*.java"/>
 </produces>
 </xjc>
 </target>Unfortunately, this causes the following error:
[WARNING] schema_reference.4: Failed to read schema document '/com/kitfox/common.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

line 24 of file:/C:/dev/kitfox.com/gameEngine/proj/tileWorld/src/com/kitfox/tw/ts.xsdI know that the classpath passed into the xjc task contains the jar with my original schema. What can I do so that JAXB finds it? Also, how would I tell JAXB to extend the classes already generated for common.xsd in my original jar rather than regenerating them in the jar I'm compiling?

Thanks. I've looked into using a catalog (the ant task allows you to specify a catalog), but don't think I've got the syntax right. Does the following look right to you?
<!DOCTYPE catalog
PUBLIC "-//OASIS//DTD Entity Resolution XML Catalog V1.0//EN"

<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"
 prefer="public">
<uri name="common.xsd"
 uri="../gb/src/com/kitfox/common.xsd"/>
</catalog>I've changed my schema to look like:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
 targetNamespace="http://xml.kitfox.com/schema/tw/ts"

 <xsd:import schemaLocation="common.xsd" namespace="http://xml.kitfox.com/schema/common"/>
 <xsd:complexType name="sourceType">
 <xsd:attribute name="uid" type="cmn:uidType"/>
 </xsd:complexType>I'm still getting errors:
[WARNING] schema_reference.4: Failed to read schema document 'common.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

line 24 of file:/C:/dev/kitfox.com/proj/tw/src/com/kitfox/tw/ts.xsdI've tried some variations such as leaving out the import/@schemaLocation attribute and hoping that the catalog could resolve that with the namespace alone or creating a fake http:// url for the schemaLocation, but none of that works. Would you know what I'm doing wrong with this catalog? The catalog and ant file are in the same directory and the relative path to the common.xsd file is correct.

Don't know how to resolve JAXB UnsynchronizedContentModel

I've got a dtd that looks something like:
<!ELEMENT Foo (Bar)*>
<!ELEMENT Bar (A, B, C)>
<!ELEMENT A (#PCDATA)>
<!ELEMENT B (#PCDATA)>
<!ELEMENT C (#PCDATA)>and a binding schema that looks something like:
<xml-java-binding-schema>
<element name="Foo" type="class" root="true">
 <content>
 <choice property="BarList" collection="list"/>
 </content>
</element>
<element name="Bar" type="class">
 <content>
 <element-ref name="A"/>
 <element-ref name="B"/>
 <element-ref name="C"/>
 </content>
</element>
<element name="A" type="value"/>
<element name="B" type="value"/>
<element name="C" type="value"/>
</xml-java-binding-schema>When I try to compile it, I gen an UnsynchronizedContentModel. Other postings in this forum suggest that my choice property doesn't correspond to the data in my dtd.
So, thinking that I need to explicitly map my list to my Bar element, I try:
<choice property="Bar" collection="list"/>
but that doesn't work, either.
All I'm trying to do is cause a List of Bar objects to be created when I unmarshal an xml file. What am I doing wrong?
In the example in the JAXB User's Guide, they complicate the issue of choice / collections by adding in the notion of an interface. I don't really have any sibling classes that share fields, so I don't see why I'd want to add this construct. However, is it necessary to do so, in order to make this work?
Thanks!
Larry

Man, do I feel stupid... finally, after banging my head up against the documentation, I found the answer.
In short, I had been telling the binding schema compiler that I wanted a list that should be named "BarList", but I wasn't telling it that it should be a list of "Bar" objects.
So, the xjs for Foo needed to look like this:
<element name="Foo" type="class" root="true">
 <content>
 <element-ref name="Bar" collection="list" property="BarList"/>
 </content>
</element>like i said, it wasn't that hard, but it sure took a lot of looking at it to realize what I'd done wrong...

I want all three files to compiled successfully.If it is compiled only then I will continue on Unmarshalling process

I suspect you are trying to compile the files one by one. You may also be trying to compile them disregarding the package structure.
From your post, I gather these files are in the package: com.geindustrial.sqms
Therefore, if they are not so already, put them under a directory structure:
com/geindustrial/sqms
and then compile with:
javac com/geindustrial/sqms/AddCtq.java com/geindustrial/sqms/Ctq.java com/geindustrial/sqms/VariableData.java
(The above is all on one line.)

How to paste DTD in XML file. (not reference to .dtd file)

Hello!
I create XML file using DOM. How can I create DTD on the top of the file?
I need the DTD, not a reference to it. So the next method won't work.
transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, "Resources\\Settings\\projectFile.dtd") since it is paste a reference to .dtd file. It means that if user moves XML file to other place he need to move .dtd file also, and I don't want this method. I want paste next DTD
<!DOCTYPE project [

]>from the .dtd file on the top of my XML file. How can I do this?
Thank you.

I've found that by opening a inputstream to the XML file and wrapping it to filter the DTD out altogether and passing that inputstream to JAXB does the trick.
this seems actually faster, since it doesn't go off on the net to look for the dtd!
is this not catered for already somewhere??
thanks,

JAXB 1.3 can't parse W3 SOAP 2003-05 envelope XML schema

Hello,
I was trying to use JAXB to parse the MMAP schema from the SMS Forum
(http://www.smsforum.net/schemas/mmap/v1.0/mmap.xsd). I finally
tracked it down to XJC choking on the included SOAP envelope schema's
use of the xml:lang attribute for a tag called reasontext. Here's the
pared-down test case:
C:\java\src\baz>%JWSDP_HOME%\jaxb\bin\xjc.bat http://www.w3.org/2003/05/soap-envelope/soap-envelope.xsd
%JWSDP_HOME%\jaxb\bin\xjc.bat http://www.w3.org/2003/05/soap-envelope/soap-envelope.xsd

C:\java\src\baz>I believe that the relevant portions of the schemas and namespaces in
question are:
http://www.w3.org/2003/05/soap-envelope/soap-envelope.xsd

</xs:attributeGroup>http://www.w3.org/XML/1998/namespace
The namespace whose name is http://www.w3.org/XML/1998/namespace is
bound by definition to the prefix xml: according to Namespaces in XML,
W3C Recommendation 14 Jan 1999. Note that unlike all other XML
namespaces, both the name and the prefix are specified; i.e., if you
want XML 1.0 processors to recognize this namespace, you must use the
reserved prefix xml:.
xml:lang and xml:space
As of the last update of this document, the XML 1.0 Specification
defines two attribute names in this namespace:
xml:lang
Designed for identifying the human language used in the scope of the
element to which it's attached.
.I'm no XML schema expert, but it looks to me like "name" and "ref"
are both valid attributes for an <xs:attribute> tag and that the XML
namespace standard requires XML processors to recognize the xml:lang
attribute. Hence, this appears to me to be a bug in JAXB.
A secondary bug is that the original error message left the name of
the offending included schema blank:

C:\java\src\baz>I'm quite interested in the resolution of this issue as I'm stopped in
my tracks on progress here. Help with resolution, whether in JAXB or
my usage of it, will be much appreciated. I did a search of existing
issues but didn't notice a duplicate. Thanks in advance.

I have also come across a similar problem with validating an xml file with an xml:lang attribute. It seems to be common across the schema validation and dtd validation. I get the following error with both schema and dtd validation:
Validation Error Msg (0): unexpected attribute "xml:lang"
Validation Error Location (0): FreeFormText
The test file extract looks like this:
<FreeFormText xml:lang="EN">Pelle</FreeFormText>
The schema defines the node as:
<xs:complexType name="FreeFormText">
 <xs:simpleContent>
 <xs:extension base="FreeFormTextType">
 <xs:attribute name="lang" type="xs:language"/>
 </xs:extension>
 </xs:simpleContent>
</xs:complexType>
and the dtd defines the node as:
<!ELEMENT FreeFormText
 (#PCDATA)>
<!ATTLIST FreeFormText xml:lang CDATA #IMPLIED >
This looks like a bug in JAXB to me aswell. Any help on it would be much appreciated as i am also stuck.

Subject: Choice element in JAXB 1.x

Recently i ran into problem of having too many elements in choice tag. JAXB doesn't throw exception, but generated files doesn't comply Java.
While compilation it throws "code too large" exception. On removing few i can manage, but i am looking for long term solution.
Any suggestion appreciated.
-Balaji S

As per my understanding the * at the end SEDOL | SILCHESTER)*> making it to create choice or replace. If you remove star from you DTD it will generate OTD without choice.
Thanks
