I want to transform an object into a XML-String

Hallo,
in my BSP I want to transform an object into a xml string to set a server side cookie.
Therefore my code is:
DATA:
    lv_xml      TYPE string,
    lv_username TYPE string.
model    ?= get_model( model_id = 'main' ).
lv_username = sy-uname.
Call TRANSFORMATION id SOURCE o = model RESULT XML lv_xml.
cl_bsp_server_side_cookie=>set_server_cookie(
        name                  = 'MODEL'
        application_name      = runtime->application_name
        application_namespace = runtime->application_namespace
        username              = lv_username
        session_id            = runtime->session_id
        data_value            = lv_xml
        data_name             = 'MODEL'
        expiry_time_rel       = 3600 ).
But after the command "Call Transformation" the xml-string doesn't contain all the data of my object, only this:
<?xml version="1.0" encoding="iso-8859-1"?>#<asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0"><asx:values><O href="#o19"/></asx:values><asx:heap xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:abap="http://www.sap.com/abapxml/types/built-in" xmlns:cls="http://www.sap.com/abapxml/classes/global" xmlns:dic="http://www.sap.com/abapxml/types/dictionary"> <cls:ZCL_M_ESS_TRV_OVW id="o19"/
></asx:heap></asx:abap>
What is wrong?
Regards.

How to convert information of a job posting into a xml string or file

hi hr experts,
I hope to find some answers.
Is there a function in the ERP system that converts all the information of a job posting into a xml string or file?
This could be used to communicate with external job databases, e.g. monster or jobpilot.
The function CALL TRANSFORMATION converts data to XML. Is this really the only way to convert the job posting?
Thanks for your feedback and help.

Save an Image object into a XML text document

ello:
I have a problem with saving an image. I need to encapsulate it into two XML tags:
<Image> xxxxxx </Image>
The "xxxx" must be a String that represents my Image object.
In J2ME I haven't serialization, and all the examples about "manual serialization" works with primitive types :(
I've already read that I can do .getRGB() over my Image object, and obtain an array of int, wich represent each pixel. Ok, I can transform the array into a String, and write it in my XML text document, but later: how I obtain my array from that String?
Thak you very much

private Image img;
byte rgb[] = null;
private rgbLength; // get lenth of your string
rgb = new byte(rgbLength);
rgb = ... //load data from string to this array
img = createRGBImage(rgb, int width, int height, false) ;You must know length of your string and must encapsulate in to XML width and height of this image;

Error while creating DocumentBuilderFactory object for parsing XML string

When I try to execute the following statement in an EJB class,
DocumentBuilderFactory df=DocumentBuilderFactory.newInstance();
I get the following exception:
javax.xml.parsers.FactoryConfigurationError: Provider org.apache.crimson.jaxp.DocumentBuilderFactoryImpl not found
When the same statement is executed from a standalone java class, it works fine.
The IDE used is Visual Age for Java.
The JAXP package used is JAXP 1.0.1
Can anybody please let me know how can we overcome this problem?
Thanks and Regards,
Shashi Anand B
E-Mail : [email protected]

javax.xml.parsers.FactoryConfigurationError: Provider
org.apache.crimson.jaxp.DocumentBuilderFactoryImpl not
foundI suspect that this may be due to a classpath issue and/or a Java version issue. Doe your Visual Age installation use Java 1.3? Do you have Sun Java 1.4 also installed on your system? It may be that when you are executing from a standalone Java class, that you are using the Java 1.4 runtime, which include the org.apach.crimson.* classes. Earlier version of Java do not include this, although it may be in the JAXP package.
I think that your Visual Age IDE is configured such that the DocumentBuilderFactory is unable to find the appropriate implementation.
I hope this helps!

Embed JavaFX object into JSPX page

Hi guys,
I developed a RIA using javaFX and now want to embed this object into a JSPX page. In the page I wrote following sentences,

javafx( { archive: "firstJavaFX.jar", draggable: true, width: 1080, height: 540, code: "path.Main", name: "firstJavaFX" } );Obviously, the logic of my script was not recognized. Instead, it's printed out directly.
So what could I do with this? Any helpful comments would be greatly appreciated.

Transforming a DART_VIEW into a DART_EXTR

Dear Gurus,
I have a problem in Data Retention Tool (DART). I had made the following steps:
- Extract the data with the transaction FTW1A (Extract Data) creating a file (BIN) u2013 ZTEST;
- Transaction FTWH (Data Extract Views) selected a view that I had previously created and put in the ZTEST file a filter (Document Type = KZ). Creating a file u2013 ZVIEW;
And now I want to have the file ZVIEW transformed into an Extract File just like ZTEST.
So for short I want to transform a DART_VIEW into a DART_EXTR. Itu2019s that possible?
I need a way to filter the file ZTEST (like document type) and have the possibility to SAVE with the same name and in the same u201Cplaceu201D.
Thx in advance,
Best regards,
Rui Ribeiro

Hello!
For the files already created you cannot change the header. It would be against to accounting principles, you should not change data already stored in production.
For the new files you can switch off the flag "insert header line" at the selection screen of the view as mentioned above.

Converting EJB Object into XML

All:
Suppose I have an EJB that is named MyDog, it has attributes as follows:
name
breed
weight
age
Is there a way to convert this Object into an XML document? Something like:
<?xml version=\"1.0\" ?>
<MyDog>
<name>Bubba</name>
<breed>Australian Shepherd</breed>
<weight>65 lbs</weight>
<age>6 years old</age>
</MyDog>
I can't find any information on doing this - any ideas, links, etc? There has to be a way to do this, but I can't find it. I'm welcome to any ideas out there!

check JAXB - might be usefull for you: http://java.sun.com/xml/jaxb/index.html

How to transform common object to xml string

I know that I can import xml dtd a the common data type in iStudio. However, does anyone know how to serialize it back to the xml string during the field mapping? Is it even possible?
Thanks,
Edward

Thanks Stuart for your reply. What I'm trying to do is to convert the xml message from the common view object to JMS Text Message. I declared the application data type as AQ$JMS_TEXT_MESSAGE and I try to map the common data type which is I imported from dtd to the application JMS type. During the mapping I need to serialize the common data type object back to xml string, so I can copy it to text_vc field defined in JMS Text Message (String type).
Or do you know any other alternative to convert from RAW XML payload type to JMS payload type in iStudio?
Thanks,
Edward

How to create XML string for an object matching the result of a marshal?

I'm trying to create a XML string representation of an object which exactly matches the XML which results from marshalling the object into a request. I'm almost there except that the XML string I come up with is missing the attribute "standalone=\"yes\"" in the topmost xml element, and this attribute is present in the marshalled XML. I'm using the XML string to create a payload signature which must match exactly with the XML payload of the request, so the two XML representations of the object really do need to be identical.
Here's what I'm doing to create the XML from the object:
   private String myObjectToXmlString (final MyObject myObject)
       throws Exception {
             try {
           DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
           Document document = documentBuilder.newDocument();
           myObjectMarshaller.marshal(myObject, document);
           Source source = new DOMSource(document);
           StringWriter stringWriter = new StringWriter();
           Result result = new StreamResult(stringWriter);
           TransformerFactory factory = TransformerFactory.newInstance();
           Transformer transformer = factory.newTransformer();
           transformer.transform(source, result);
           return stringWriter.getBuffer().toString();
       } catch (Exception ex) {
           throw new Exception("Unable to convert a MyObject object to an XML String -- " + ex.toString(), ex);
   }The XML which is produced looks like this:
<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<ns2:myObject xmlns:ns2=\"http://sunconnection.sun.com/xml\">
   <myObjectId>0</myObjectId>
   <objectType>1</objectType>
   <description>Test Object</description>
</ns2:myObject>The payload object is marshalled to the request like so:
    // marshall the MyObject to the output stream
   OutputStream outputStream = myHttpUrlConnection.getOutputStream();
   myObjectMarshaller.marshal(myObject, outputStream);
   outputStream.flush();
   outputStream.close();When I view the XML payload of the request it looks like this:
<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>
<ns2:myObject xmlns:ns2=\"http://sunconnection.sun.com/xml\">
   <myObjectId>0</myObjectId>
   <objectType>1</objectType>
   <description>Test Object</description>
</ns2:myObject>As you can see the two XML representations of the object are identical except for the standalone attribute in the xml element.
It'd be a hack to make the assumption that the standalone attribute will always be there in the marshalled object and to just hard code it into the XML string returned by my object to XML method. Since I'm using the same Marshaller to create the XML string as I am to perform the marshalling to the request I assume that there's some way to make it give the same XML in both cases, and that I'm doing something wrong in my method which converts the object to an XML string. If anyone can see where I'm going wrong in that method (myObjectToXmlString() above), or can suggest a better way of doing this, then I'll certainly appreciate the insight.
--James

It turns out that I was taking the wrong approach in my object to XML string method. A cleaner/better way to do it, which gives the correct result, is this:
    private String myObjectToXmlString (final MyObject myObject)
        throws Exception {
        try {
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            myObjectMarshaller.marshal(myObject, stream);
            return stream.toString();
        } catch (Exception ex) {
            throw new Exception("Unable to convert a MyObject object to an XML String -- " + ex.toString(), ex);
    }--James

Can we include a Document into a XML Form

Hi!
If I want to attach a document into a XML Form is posible?
i.e an Excell Document.
Thanx in Advanced!
Gerardo J

Hi Gerardo,
The info it's on my brain, jejeje, I have some experience with XML Forms. I really don't think you can attach (by standard/default) anything to an xml form, everything is a refence (even images).
XML Forms generates xml files, witch are rendered thru layouts and the configuration you set in the RenderList and Show forms.
Unless you find some kind of deployment that unifies the xml document with the file you want you will have to work with the references (link).

Using Simple Transformations with Objects tt:copy .. results in Exception

Question:
How can I serialize an ABAP-Object-Instanz with my own simple transformation?
In the sap-documentation I found the following solution for the serialisation of any data-objects.
"z_steffens_simple_transf":
<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">
<tt:root name="ROOT"/>
<tt:template>
    <root>
      <tt:copy ref="ROOT"/>
    </root>
</tt:template>
</tt:transform>
Following the example I wrote this report:
report zspahr_test_simple_transf.
class serializable definition.
public section.
    interfaces if_serializable_object.
    data attr type string value 'Attribute'.
endclass.
method main_serializable.
    data: oref type ref to serializable,
          xmlstr type xstring.
    create object oref.
    call transformation id
      source root = oref
      result xml xmlstr.
    call function 'DISPLAY_XML_STRING'
      exporting
        xml_string = xmlstr.
    call transformation z_steffens_simple_object
      source root = oref
      result xml xmlstr.
    call function 'DISPLAY_XML_STRING'
      exporting
        xml_string = xmlstr.
endmethod.                    "main_
start-of-selection.
demo=>main_serializable( ).
Executing this report leads to an exception "CX_SY_REF_NOT_SUPPORTED".
The "standard" transformation "ID" ist working an translates my object-instance into an asXML representation:
<?xml version="1.0" encoding="utf-8" ?>
- <asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0">
- <asx:values>
<ROOT href="#o3" />
</asx:values>
- <asx:heap xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:abap="http://www.sap.com/abapxml/types/built-in" xmlns:cls="http://www.sap.com/abapxml/classes/global" xmlns:dic="http://www.sap.com/abapxml/types/dictionary">
- <prg:SERIALIZABLE xmlns:prg="http://www.sap.com/abapxml/classes/program/ZSPAHR_TEST_SIMPLE_TRANSF" id="o3">
- <local.SERIALIZABLE>
<ATTR>Attribute</ATTR>
</local.SERIALIZABLE>
</prg:SERIALIZABLE>
</asx:heap>
</asx:abap>
How can I do this with my own Simple Transformation "ZSPAHR_TEST_SIMPLE_TRANSF" ?
I want to serialize my object using my own xml-structure, not the asXML-structure !
Regards
Steffen

Hi,
try like this,i think it may help you.
ABAP:
CALL TRANSFORMATION ztrans_test
      SOURCE
           root = partab
     RESULT XML lv_xstring.
Trnsformation:
<tt:root name="ROOT" type="?"/>
<tt:template>
<VALUES>
<VALUE_SOURCE>
        <tt:value ref=".ROOT"/>
</VALUE_SOURCE>
<VALUE_PARAM>
<tt:value ref="NAME"/>
<tt:value ref="VALUE"/>
</VALUE_PARAM>
</VALUES>
Thanks,
Rajesh.
