Sounds like the web service portion of the process is already complete, so that remaining problems are
  • Obtaining a location to save the file to.
  • Saving the file to the file system.
  • Viewing the file from the file system.

  • Example: Opening PDF file in a standalone Java Swing application

    No, My problem is that the pdf file generated is on Server machine and my client wants to view and save it on his local machine. For that I need the code, if possible.

    Thanks in advance:)

    You can send/receive it as byte array so that you dont need to scratch your head about interoperability with non-java client.

    On the other hand you can also use SAAJ API along with Axis1.2 to send and receive file as soap attachment. Worked out sample can be found here.

    >>Please send me the code ?
    What code you are looking for ?
    Many sample codes can be found in the samples directory of Axis1.2.

    Regards
    Balaji

    Given that Netbeans 6.1 is being used, JAX-WS should already be supported and MTOM should be the first choice for binary attachments.

    Sorry removing the post as Ulf Dittmer very correctly pointed out that the conversion can be done from XML to PDF and not the other way.
    Thanks Ulf and sorry Lokesh.

    Apache FOP can NOT convert PDF to XML; it does just the opposite - create a PDF from XML with the help of an XSL-FO transformation.

    I have tried to figure out a way to get the pdf contents as string.You can then convert these string objects as per your requirement.
    Hope this helps..Please find the java code below.YOu can test it with a pdf.You willl need some jars.You can get them at findjar.com and the main jar at www.pdfbox.org.

    The following is a JDK 6 example of a JAX-WS SOAP web service that stores and returns PDF files.
    Consider the following XML Schema:

    Both documentContent elements are based on {http://www.w3.org/2001/XMLSchema}base64Binary and the {http://www.w3.org/2005/05/xmlmime}expectedContentTypes attributes triggers the mapping to standard Java types. In the case of application/pdf the content will be mapped to a javax.activation.DataHandler (see also 6.2.1.2. xmime:expectedContentType to Java type mapping).

    This schema can be used in a web service contract

    Before processing some binding files are necessary to specify some options.

    A JAX-WS binding file
    which maps the Java web service artifacts to the com.coderanch.jaxws.mtompdf.ws package.

    A JAXB external binding customization file
    which maps the JAXB artifacts to the com.coderanch.jaxws.mtompdf.dto package.
    wsimport PdfStore.wsdl -b PdfStore-jaxws.xml -b PdfStore.xjb -s src
    generates the following Java artifacts:
  • com.coderanch.jaxws.mtompdf.ws.PdfStore - the endpoint interface (SEI)
  • com.coderanch.jaxws.mtompdf.ws.PdfStoreService - the web service client proxy
  • com.coderanch.jaxws.mtompdf.ws.PdfStoreException - the web service Exception/Fault
  • com.coderanch.jaxws.mtompdf.dto.GetRequest class to represent {http://mtompdf.jaxws.coderanch.com/}Get.
  • com.coderanch.jaxws.mtompdf.dto.GetResponse class to represent {http://mtompdf.jaxws.coderanch.com/}GetResponse.
  • com.coderanch.jaxws.mtompdf.dto.PutRequest class to represent {http://mtompdf.jaxws.coderanch.com/}Put.
  • com.coderanch.jaxws.mtompdf.dto.PutResponse class to represent {http://mtompdf.jaxws.coderanch.com/}PutResponse.
  • com.coderanch.jaxws.mtompdf.dto.PdfStoreFault class to represent {http://mtompdf.jaxws.coderanch.com/}PdfStoreFault.
  • com.coderanch.jaxws.mtompdf.dto.ObjectFactory - the JAXB ObjectFactory.
  • package-info.java containing the JAXB package level annotations.


  • We still need a utility class to deal with the PDF files and DataHandlers:

    Now the Web Service can be implemented.

    Note how @javax.xml.ws.soap.MTOM is used to turn on MTOM support.

    The code to host the endpoint (with com.sun.net.httpserver.HttpServer).

    To compile everything:
    javac -d . src\com\coderanch\jaxws\mtompdf\util\*.java
    javac -d . src\com\coderanch\jaxws\mtompdf\provider\*.java
    wsgen -cp . com.coderanch.jaxws.mtompdf.provider.PdfStoreImpl


    Start the web service with:
    java com.coderanch.jaxws.mtompdf.provider.Main

    Point a browser to http://localhost:8080/wsdemo/pdfstore?wsdl to see the JAX-WS generated WSDL.

    Open a separate console window to work on the web service consumer.

    Note the use of javax.xml.ws.soap.MTOMFeature to enable MTOM on the client side.
    Compile it with
    javac -d . src\com\coderanch\jaxws\mtompdf\consumer\PdfStoreClient.java
    and run it with
    java -cp . com.coderanch.jaxws.mtompdf.consumer.PdfStoreClient
    after you place a test.pdf file in the working directory. test1.pdf should appear after the client "puts" the file to the service. test2.pdf should appear after the client "gets" "test1" and saves it as "test2".
