How to omit xmlns from generated Java classes

Hi,
I'm using JAXB and xjc to generate Java classes from xsd fils. I've noticed that when marshalling these Java classes to XML string, there are few xmlns attributes that (as far as I concern :-))
"waste" space on the generated xml (space is critical resource in our application). Is there a way to order the Marashaller to omit these xmlns attributes from the generated files?
I tried to edit the generated xml string. I removed the xmlns attributes, but unmarshall it back to Java objects failed...
Thanks for any help,
Barak.

If the xmlns is specified in the xsd, it is also required in the xml. If you do not want it, however you can remove it from your xsd and then generate your xml

How can I call a pop up window from a java class ?

It was possible to do it in ASP .NET even from the server side with the method Page.ClientScript. What do you think what Page.ClientScript stands for?
I's an encapsulation for the JavaScript code required and hides the separation between frontend and backend. There was a reason why so many developers stick to the MVC-pattern wich ist violated here.
I did not know it is not possible to do the same thing in Java.I'ts not a task of the backend to layout the user interaction GUI.

How to call a Java class from another java class ??

Hi ..... can somebody plz tell me
How to call a Java Class from another Java Class assuming both in the same Package??
I want to call the entire Java Class (not any specific method only........I want all the functionalities of that class)
Please provide me some slotuions!!
Waiting for some fast replies!!
Regards
Smita Mohanty

Hi Smita,
you just need to create an object of that class,thats it. Then you will be able to execute each and every method.
e.g.
you have developed A.java and B.java, both are in same package.
in implementaion of B.java
class B
            A obj = new A();
             //to access A's methods
             A.method();
            // to access A's variable
            //either
           A.variable= value.
           //or
           A.setvariable() or A.getvariable()

Errors generating Java classes from XML schema

I received the following errors when generating Java classes from the schema located at: http://imsproject.org/xsd/ims_qti_rootv1p1.xsd and http://imsproject.org/xsd/ims_xml.xsd
XML Spy v4 claims that the schema is well-formed and valid. Could this be a problem with the class generators, or is XML Spy not telling the truth?
Thanks.

About generating Java classes from XSD Schema ???

I need a powerfull tool to generate Java classes from XML Schema. I want that generated classes to have the option to validate XML(to be JAXP1.2 compliant).
I used XML Spy 5.4 but the generated classes can't validate an XML file.
Can you help me with other tools that:
- generate Java classes from XSD
- generate sample XML from XSD
- are JAXP1.2 compliant(validate a XML file with a schema)
Thanks.

You can also use Castor: http://www.castor.org
It generates classes from XML Schemas and enables data
binding without writing any line of a fuckin SAX
parser :-)I evaluated Castor and JAXB and while JAXB isn't perfect, it's got some things over Castor. Castor almost looks abandonded when I go to the site. The documentation just sort of trails off.

Error when generating Java Classes from XSD

I'm getting the following error when using oragc to generate Java classes from a schema:
Error: Schema Class Generator failed to generate classes. oracle.xml.parser.schema.XSDException: Invalid facet 'pattern' in element 'simpleType'
Any thoughts?
Here's the part where it is getting the error:
+111 
+112 <xsd:simpleType name="TimestampType">
+113 <xsd:annotation>
+114 <xsd:documentation>Base type for a date and time stamp</xsd:documentation>

+118 </xsd:restriction>
+119 </xsd:simpleType>

I would recommend using JAXB instead of the Oracle class generator. This will give a standards based object-to-XML platform.
Oracle provides two JAXB implementations: one in the TopLink product, and the other in the XDK.
For an example of using TopLink JAXB see:
http://www.oracle.com/technology/products/ias/toplink/technical/tips/jaxb/index.htm
TopLink also provides the ability to map existing Java objects to an existing XML Schema, for an example of this see:

How to execute a jsp instruction from a java class?

How to execute a jsp instruction from a java class?
Any help please.
Thank's

I'll detail my problem:
Supposing that I have a jsp file called: start.jsp
In the start.jsp I instanciated an object called global from the class Global ( for example ).
Then, I called a custom taglib:
<ix:mytag/>
In the suitable tld file: the mytag is defined:
<tag>
<tag class>Tag1<.....
The java file Tag1 has method:
doStartTag(){
// here is the problem
global.doSomeFunctions();
Okay, the problem is that the object gobal is not defined in the class Tag1. what to do?
I think that I have to pass the object global as a parameter to the class Tag1. How to do that?
Actually, the problem was to insert the follwoing in the doStartTag method:
doStartTag(){
pageContext.getOut().print("<%= hello world %>");
The output is <%= hello world %> not hello world.
Okay, the new problem is how to pass an object as a parameter to a class called from a tld file.
Any help please.
Thank's too much

JAXB problem generating java classes

Any answers will do

Well, after hours of digging I found a solution which actually was right in front of me the whole time.
This is how I edited the schema.
    <xsd:complexType name="options">
        <xsd:sequence>
            <xsd:element name="option" maxOccurs="unbounded" >
                <xsd:complexType>
                    <xsd:simpleContent>
                        <xsd:extension base="xsd:string">
                           <xsd:attribute name="value" type="xsd:string" >
                              <xsd:annotation><xsd:appinfo>
                                <jaxb:property name="realValue" />
                              </xsd:appinfo></xsd:annotation>
                             </xsd:attribute>
                        </xsd:extension>
                    </xsd:simpleContent>
                </xsd:complexType>
            </xsd:element>
        </xsd:sequence>
    </xsd:complexType>Before, I placed the <xsd:annotation> tag efter the first line but inside the <xsd:attribute> made much better if you would like it to work.
When marshling an @XmlRoot object will produce valid xml code. So even though that the server have a different xml schema, they will be able to talk to each other.

Customization of generated Java class names

Hi,
I could not find any documentation on how to customize names of the generated
Java classes/types. In Castor, you can do it with a simple mapping, is it possible
with XMLBeans?
Thanks,
Marina

Hi, Steve,
thanks for your reply!
I have tried to add an xsdconfig file, but when I run the following command:
C:\Java\XMLBeans\xkit\bin\scomp -src . -srconly order.xsd
with the xsdconfig file in the current directory , nothing happens - the xsdconfig
file is ignored and Java files are generated in exactly same way as they were
without the xsdconfig file...
Here is the content of my xsdconfig file - it is very simple, for test purposes:
<xb:config xmlns:order="http://order"
xmlns:xb="http://www.bea.com/2002/09/xbean/config">
<xb:namespace uri="http://order">
<xb:package>neptune.neptunelib</xb:package>
</xb:namespace>
<xb:qname name="order:order" javaname="OrderDO"/>
<xb:qname name="order:shippingID" javaname="ShippingInfoDO"/>
<xb:qname name="order:addressInfo" javaname="AddressInfoDO"/>
<xb:qname name="order:destination" javaname="DestinationDO"/>
</xb:config>
I'm not sure about the namespace part - currently, my order.xsd has no namespace
or URI assigned. I asked BEA's customer support about this and the answer was:
'use anything, the URI does not matter'. Well, I did use "anything" but I'm not
sure this is correct...
Thanks,
Marina

Accessing managed-beans property from simple java class

I have managed bean that is registered in faces-config.xml:
<managed-bean>
<managed-bean-name>documentReportsBean</managed-bean-name>
<managed-bean-class>[myApp].beans.DocumentReportsBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
I want to access property of documentReportsBean from other java class without registering managed-property in faces-config. How can I do that?

Thank you, what I needed was someone saying the right word. "ValueBinding" in this case.. :)
Two lines:
ValueBinding vb = FacesContext.getCurrentInstance().getApplication().createValueBinding("#{documentReportsBean}");
DocumentReportsBean pbean = (DocumentReportsBean) vb.getValue(FacesContext.getCurrentInstance());
gives my full control. Nice
