Generate XML file from RFC using Web Services

  I am trying to save an RFC enabled Function Module output to an XML file using ABAP web services.
I could able to create Web Service and release it using WSCONFIG/WSADMIN. I can actually get the output in XML file when i launch the web service home page. But I need this to be done in the ABAP program itself. So If i run the RFC I could able to create,release web service and capture the Generated XML file by SOAP runtime.
Any FM available?

which version of WAS you are on .
if you are on WAS6.40 check the following weblog on how to consume webservice using the wsdl file.
lower version of WAS use class cl_http_client.
if this case you have to manually build the soap message.

  • Generating XML file from WORD file

    I am trying to generate xml file from a word file.
    but i am stucked with how to do it? any kind of help will be useful.
    i think for doing this work i have to develop XSD file, because when i am creating the xml file, the hidden space within the word file is not catched.
    please help me out.
    waiting for reply

    after searching on the net i came to know that org.apache.poi.hwpf.* is used for reading word file and its contents. for converting it to xml i have to use org.exolab.castor.xml.*
    now my problem is that POI is in its early beta version and there is no help or any sample examples for understanding the api.
    so if you have any idea regarding it, please write to me.

  • Generate XML File from table

    How to generate XML file from a table without using UTL_FILE that too in local machine...

    You downloaded the wrong XML Parser!
    XSQL requires Java Parser. Well, there's a copy included with the XSQL package so you actually don't need to do another download.
    You really don't need XSQL if you just want a XML file from DB, you just needed a XML SQL Utility. Download that and run the samples.

    Hi I need this asap... "Java code to generate XML File from XML Schema i.e XML Schema Definition, XSD file".
    Thankz in advance...

    JAXB has been available as an early release download for some time. There are also XML Binding packages available from Borland (JBuilder) and Castor. These tools create Java classes from a source document, xml,dtd etc. You can use these classes to marshal-unmarshal XML documents.

  • How to generate XML file from SQL file !

    I am new to XML publisher. I known one way to generate XML file is register one report file in concurrent manager.
    But I want to generate XML file from sql file.
    Could someone show me how to code in sql file, how to register is in concurrent manager.
    Thanks !

    Phew ... not sure we have the space here. So I can point you in the right direction:
    1. XML data generation - there are two packages in the db you can use with a plsql procedure, XMLGEN and SQL XML. You can also use java APIs too. Try checking the db documentation and search for the above methods.
    2. Registering the report - the system administrators guide will provide this info. Hooking the program up with XMLP is covered here -

  • Sending XML from ABAP using  WEB Service 6.20 to an external server

    Can anyone help me to send XML file from WAS 6.20 using ABAP withouut XI?
    I am trying to send an XML file to an external server from ABAP.  I have created the RFC destination in SM59 with address.  I am able to make connection to the host but the whole XML file is not delivered to the receiving.

    if you want to push, then the other system should have some mechanism to receive it, they can be ftp location, http point, or a webservice. check with external system what do they support.
    based on what the external system can support , we can come up with further suggestions.

  • Best Practices:: How to generate XML file from a ResultSet

    Hi all,
    Could someone please suggest the best practices of how to generate an XML file from a resultset? I am developing a web application in Java with Oracle database and one of my tasks is to generate an XML file when the user, for example, click a "download as XML" button on the JSP. The application is basically like an Order with line items. I am using Struts and my first thought has been to have an action class which will extend struts's DownloadAction and through StAX's Iterator API to create an XML file. I intend to have a POJO which will have properties of all columns of my order and line items tables so that for each order I get all line items and:
    1. Write order details then
    2. Through an iterator write line items of that order to an XML file.
    I will greatly appreciate for comments or suggestions on the best way to do this through any pointers on the Web.

    Use a OracleWebRowSet in which an XML representation of the result set may be obtained.

  • Accessing config information in XML file in a Weblogic web service (JWS)

    I have implemented a web service for sending emails and pages via Java Mail and SNPP respectively using WebLogic Workshop on the BEA WebLogic 8.1 platform. In the service, I use certain pieces of information that are currently stored in an XML file on disk. Also, in its current state, the web service is implemented with public methods directly in the .jws Java file and not as a session bean. The file read from disk is performed every time the web service operation to send a message is invoked. As we all know, the I/O files access is very expensive and a performance bottleneck, especially when it is incurred on every invocation of the web service ‘sendMessage’ [operation.
    Without radically re-writing the application, I am looking for a way to improve the performance of the web service and can only come up with the following 2 ways:
    1) Move the code out of the sendMessage operation: Here, the main question I have is 'to where should I move it to'? I have seen in the WebLogic Workshop documentation that WebLogic Server maintains only a single instance of a Java class that implements a Web Service operation, and each invoke of the Web Service uses this same instance. In that case, I should be able to put the code in the constructor so that the files is read only at the time the class is instantiated, but a constructor in the .jws file that contains the web service operations itself does not seem to be invoked by the container (I tried to put a breakpoint in the constructor, but it seems that the constructor code never gets called)
    2) Move the configuration variables into some type of standard configuration file of WebLogic, something like web.xml or wlw-config.xml or files. But I found that these XML files have an associated schema to conform to and do not provide any custom elements or attributes that I could add for my application(is that true?). Also, if I can somehow put the configuration information into any of these standard files, how do I access it from within the application 'without' doing a file read from disk? Are these configuration file items available in memory for access and use by the web service and if they are, what API can I use to access and use them?
    Any and all ideas are welcome!

    I have been looking into a similar problem. Since web services are by design stateless, they aren't good for 'remembering' information between calls. Aside from a file read, the only other solution I have found is to use a database. You can make use of an entity bean or simply make some kind of JDBC call. I don't know if you need to stick with the config file, but if so maybe you could read the config data into a database once and then you might have faster access than reading from a file. I'm not sure about which would have better performace, but its all I have come up with so far. What parser are you using to read your XML file? Have you tried others to see if they have better performance?

  • OutofMemory Error while sending file to database using Web services

    I have a file of 30MB to be written to the MySQL database. I am doing this in Axis web services and it gives me the following error:
    (I am using Tomcat as the application server and Apache as the web server, Axis 1.3 and MySQL standard 5.0.21 version. I have set the minimum and maximum heap size and it works well without using the web service (just uploading and downloading from the database using a simple java program). Another thing to notice is that I can send a file of almost 10MB size to the database using web service without any problem. But it doesn't work with the 30 MB .)

    Sorry for the delayed response here, forget to add it to my watchlist. I didn't catch if you were using Java 1.5 or not. Prior to 1.5 the default maximum heap space was 64MB which with the overhead of the appserver might be your problem.
    Take a look at and the java -Xmx <size> command line option to change the default (I believe the size argument is in bytes, but don't hold me to that). I think you can pass that as a command line option to the startup script, but you should check the doco to see if it needs to be wrapped in some other arg etc.,
    I seem to recall running into this same problem a few years back when I had a servlet doing some intense graphics processing on the fly and setting this option fixed the problem.
