Error generating a record based on a DTD (IS4.6, Developer 4

  • 1.  Error generating a record based on a DTD (IS4.6, Developer 4

    Posted 09/05/02 10:40 AM

    Hello,

    I am trying to generate a record, based on a DTD.

    • I am using jdk 1.2.2_011 (supported, according to wM documentation)
    • I have been successful on another machine (so I guess it must be related one way or another with the my installation)
    • the DTD is 100% correct. I have tried several other easy DTD’s and always receive the same error !
    • I have tried jdk 1.3.1 and encountered the same problem
    • I have been succesful in compiling some java services, so there is nothing wrong with my compiler (I have adjusted the classpath in the server.bat file to reflect the c:\jdk1.2.2 directory)

    Here is the error message that I get:

    java.lang.NullPointerException

    I urgently need to get this to work !

    Any help is kindly appreciated !

    I am looking for a service to validate an xml file against a DTD. Ideally the service would accept two input files (xml file, DTD file) and return a valid/invalid result.

    This can be easily done if I convert the DTD to a record/schema manually using the Developer, but I want to do the whole job in a service.

    By viewing the audit log I see that Developer does its job using several non-exposed services:
    wm.server.ns:nodeExists
    wm.server.ns:isNameValid
    wm.server.schema:generateFromDTDString
    wm.getRegistry

    This tells me that the job should be doable, but it would take a lot of reverse engineering in the absence of specs on these internal services.

    Has anyone looked into this?
