Client Using the Java Interface

See also the delivered example XMMInvoker and XMLRPCService (EntireX XML/SOAP Runtime).

Step 1: Writing the Client Program

Start of instruction setTo write the client program

  1. Initialize the Broker Object

    Broker broker = new Broker(brokerID, userID);
    // if a logon should be issued
     broker.logon(password);
  2. Initialize the XMLRPCService Object

    XMLRPCService service;
    service = new XMLRPCService(xmmfilename);//constructor with XMM

    or

    XMLRPCService service;
    service = new XMLRPCService(broker, serverName, xmmfilename);
  3. Initialize the Conversation Object

    For one XMLRPCService, only one conversation may be used at a time.

      private Conversation conv;
      conv = new Conversation(service);
  4. Assign the incoming XML document:

    String xmlDocument = "<?xml version="1.0" encoding="iso8859-1"?>" +
    "<CALC Operation=\"-\" Operand_1=\"1000000611\"
    Operand_2=\"1000000288\"></CALC>";
  5. Invoke the Service

    Non-conversational

    try
    {
      String result = service.invokeXML(xmlDocument);
    }
    catch (XMLException e)
    {
       // Error handling ...
    }
    catch (BrokerException e)
    {
      // Error handling ...
    }
    catch (Exception e)
    {
      // Error handling ...
    }

    Conversational

    try
    {
      service.setConversation(conv);
      String result = service.invokeXML(xmlFromFile(filename));
      service.closeConversationCommit();
    }
    catch (XMLException e)
    {
       // Error handling ...
    }
    catch (BrokerException e)
    {
      // Error handling ...
    }
    catch (Exception e)
    {
      // Error handling ...
    }

    The string result contains the returned document. It should be:

    <CALC Function_result="899" />

The HTTP Interface

The HTTP interface supports HTTP POST Request and HTTP GET Request. The following HTTP headers and parameters are available:

Header/Parameter Direction Description
exx-brokerID IN If this attribute is set, it overwrites both the properties of the XMM file and the settings of the servlet initialization.
exx-service IN The service name is the triple set of server class/server name/service. If this attribute is set, it overwrites both the properties of the XMM file and the settings of the servlet initialization.
exx-userID IN The userID specified here is used for calling the broker.
exx-password IN The password specified here is used for calling the broker.
exx-use-security IN Possible values: true | false. This optional parameter determines whether EntireX Security is used. If the parameter is not defined for the XML/SOAP Listener / XML Tester (Quick test), the runtime determines if EntireX Security is required or not. If this parameter is defined, the behavior is fixed depending on value. See EntireX Security for EntireX Broker.
exx-encryption-level IN Possible values: 0 | 12. See ENCRYPTION-LEVEL, class Broker and method setSecurity.
exx-rpc-userID IN The RPC user ID specified here is used for Natural Security. If no RPC user ID and no RPC password is defined, the values of exx-userID and exx-password are used for these values.
exx-rpc-password IN The RPC password specified here is used for Natural Security. If no RPC user ID and no RPC password is defined, the values of exx-userID and exx-password are used for these values.
exx-natural-security IN Possible values: true | false. Determines whether Natural Security is used. See Using Natural Security in the Java Wrapper documentation.
exx-natural-library IN The Natural library. Applicable only if exx-natural-security is "true". See Using Natural Security in the Java Wrapper documentation.
exx-use-codepage IN Determines the translation processing of the EntireX Broker. Valid values: true | false | <character encoding>. If a character encoding is set, this character encoding is used for RPC message. See method useCodePage and setCharacterEncoding in the documentation on class BrokerService (EntireX Java ACI).
exx-compresslevel IN Sets the compression level. See Using Compression under Writing Advanced Applications - EntireX Java ACI.
exx-compression IN Possible values: true |false. See Using Compression.
exx-xml-sessionID IN OUT This HTTP header is returned from the servlet to the client application. If the client returns it to the servlet with the preceding call, the same session will be used. For conversations, the exx-conv parameter is also required.
exx-xml-info OUT In this HTTP header additional information is returned.
exx-xml-error OUT In this HTTP header error information is returned.
exx-conv IN Possible values: OPEN | COMMIT | BACKOUT.

Conversations can only be used in connection with sessions. If the session is interrupted, the conversation is deleted.

exx-reliable IN Possible values: AUTO-COMMIT | OFF.
