Axis client: Always creating null-element even if I dont set it

I am using Axis client to integrate with Webmethods.
They have a type specified with:
<element name="x" type="string" minOccurs="0"/>
I do not want to set the value in the field because the value is unknown for me. So I choose not to set it at all and everything would be fine if not Axis sets it for me as a null-element.
How do I get around this? I have to do it on the client side, because the webmethods system is not changeable.

Always create any Object even without default constructor?

hi!
i'm wondering if there's an easy way to construct an object of a given class?
let's assume i've got a class
class MyClass
public MyClass( OtherClass c)
}now when i get the constructors for its Class-object with
clazz.getDeclaredConstructor()
it will return null;
ok now i know ther's no default/empty constructor.
does it make sense to then search for the next constructor with n parameters?
and then invoke it with nonsense values?
what happens if the parameter classes also have no default constructor to create parameter objects? like this:
class OtherClass
public OtherClass ( MyClass c)
}now there's a loop between the two constructors and i can't create empty parameter values to invoke any of them!
i wonder how the serialization engine works then?
or did i miss something trivial (it's really late here ;) )

What's the problem? To create a MyClass object, you
don't need any OtherClass objects. You just do the
equivalent ofnew MyClass(null)in your
reflective code.
slap forehead with toilet
thanks for the tip.
as i said there was something absolutely easy, it's tough not seeing the forest for the trees ;/
But I agree with jschell, if your requirements are to
create objects of arbitrary classes and call
arbitrary methods with arbitrary parameter lists,
then whoever did your design didn't think for long
enough.WELL. you're absolutely right. but when it's time to process ANY given object there's no reliability on whatever design was chosen. or, would you insist the developer had to provide standatized formats when you write a debugger? no it has to work with any. so must i!

Inhibit output per axis is always active, even if i KILL the axis in max

Hi,
I'm using pci-7344 with UMI-7774 and 3'rd party servo drive.
everything works fine but the inhibit output signal on the axis,
it is always ON and never changes state even when i press "Kill" the axis in MAX.
I know that the inhibit output per axis on the UMI (wich ia named "Enable" in the UMI manual) is a combination logic
of some signals in the umi, for example: if the Fault signal is asserted then the "Enable" signal is asserted also.
in order to debug the problem, i set the other signals that affect the "Enable" signal to value that i can be sure
that will not affect the "Enable" signal, i do that so i can be sure that when i press KILL and Halt in MAX, the Enable sould be toggle off/on.
The "Fault" input signal per axis on the UMI (User-supplied external Fault input (per axis)): i set the jumper in the UMI to "Active low", and connect the Fault+, Fault- to always be high, so the UMI
always "think" that there is no errors from the servo drive.
i made the wiring for the "fault on the UMI as described in :
Figure 3-8. Example of Wiring a High-Side Switch to the Fault Input , page 3-10 in the UMI manual.
Same thing i do for the "Inhibit All" signal on the "Global Stop" connector on the UMI , as described here:Same for the Shutdown on this global stop connector.
Now, i think, i can be sure that when pressing KILL the Enable sugnal need to change its state, nothing happened....
i notice these thing: measuring the volt between the "Enable" pin on the axis
and the Ciso, i get always +24VDC. is that should be 5V... ?
there is a lot of names for the same signal that makes the debugging more difficult (Enable, INOUT1, INALL, inhibit output, per axis, etc...)
P.S. i also can see any LED in the UMI that is Lit, only the "Power V , Viso" LED is Lit.
Please someone make this issue clear for all, cause i see a lot of posts in the forum of people who ask about
the inhibit output per axis or in its other name "Enable" signal that output from the UMI per axis.
Thanks

Hello Eric,
Thank you for your reply, i'm trying to solve this for long time.
I follow your instructions about the switched on the UMI and setting the parameters in MAX, re-initilized and .. the problem is still there...
These is the configuration i made, i hope that something here will help you to help me solving this problem:
1.  I'm using only one Axis on the UMI, so i set in mac all other axis to disable in the Axis Configuration tab.
2. The Axis that i'm using (Axis4) configured in this way :
     in "Motion I/O Settings" tab of this axis:
     Forward, Reverse,Home Limit switches is all "Enabled" and "Active High Polarity"
     Software Limit setting (Forward and Reverse) : Disabled
     Inhibit Output setting :     "Enabled" and "Active High Polarity"
     Inhibit Input setting : is grayed, cant set its parameter (i see (in the grayed) that its set to : Disabled)
3. In UMI-7774:
     All the Axis that i dont use and set in MAX to Disabled, their switches in the UMI is "Active Low"
     i dont use them, and i tink its not relevant for which value they set, but this is the facts for troubleshoot this problem.
    The Axis that i'm using: Axis4 , the switches on the UMI board is set to :
     FAULT       : Active Low
     ENABLE    : Active High
     LIMIT LED : Active Low
     On the UMI, only the Power V, Viso LED are Lit, all other LED in the umi:
      Inhibit All, Interlock, and each axis Leds (Disabled,Fault,Home,Fwd,Rev) are all not Lit .
4. i connect 9-Pin cable to the "Global Stop" on the UMI, so i can set the "Inhibit All" , "Shutdown" input signals ,
     which are "user supplied" input signals. they are now connected directly to the C-Iso,
     cause i want them not affect the "Enable" signal on the Axis that i'm using (i hope that connectng them to the Ciso is the
     right decision, cause i dont know where to set their polarities..if i need to..??? )
5. The "Fault" signal for the axis that i'm using (Fault+, Fault-) is connected to Viso and Ciso, later when i know that the Enable signal is
     working, i'll connect these (Fault+, Fault-) to the Alarm signal from the Servo Drive.
     currently i connect them diectly to Viso and Ciso, again, cause i want them not affect the "Enable" signal on the Axis that i'm using.
i think that comletes the setting according to the UMI user manual, page 3-11...
The thing that i dont understand here is that the manual is writtent that the "Controller Axis Inhibit Out (per axis)"
is affect the "Enable" signal, and i though that the "Enable" signal is itself the "Inhibit Out (per axis)"
so, i'm sure measing something here...
Thanks for helping with this, i'm really on the last configuration of the servo, cause everything else
is working good, encoder, Dir, Puls, commands to the servo using MAX 1D interactive, and LabView programs all working well,
p.s. now i;m manualy give input for the servo on signal , i want that the "Enable" will do this job..
Thanks

?? can not create an instance of org.apache.axis.client.Service

hi,
firstly, i should introduce what i am doing now.
I want to write a Jeanbean, which can invoke 2 web services.
I found in tomcat, when I submitted the parameters from a web page form, there was Internal Server Error.
The problem is I can not created an instance of org.apache.axis.client.Service, or an instance of org.apache.axis.client.AxisClient.
But very stange, I tried to create an instance of org.apache.axis.client.Transport, which should exist in the same package with Service and AxisClien, there was no exceptions.
can anyone give me some hints?

Is it a "class not found" error? Have you tried viewing the jar file that you think org.apache.axis.client.Service is in to be sure that it's really in there?

Creating optional elements using SQL / XML functions

Hi,
I am struggling with some SQL / XML functionality in order to create some optional elements in a XMLType.
I have one table with data to be generated into an XML document. The table looks like this (only the attributes related to the problem are shown):
msg_id (pk)
geslacht_hoofdverzekerde
geboortedatum_hoofdverzekerde
geslacht_medeverzekerde
geboortedatum_medeverzekerde
I have to create an XML document that looks like this:
<ber:rekenparameters>
<ber:verzekerde>
<ber:codeRelatierol>HVZ</ber:codeRelatierol>
<ber:geslacht>M</ber:geslacht>
<ber:datumGeboorte>01-01-1960</ber:datumGeboorte>
</ber:verzekerde>
<ber:verzekerde>
<ber:codeRelatierol>MVZ</ber:codeRelatierol>
<ber:geslacht>V</ber:geslacht>
<ber:datumGeboorte>01-01-1961</ber:datumGeboorte>
</ber:verzekerde>
</ber:rekenparameters>
Where <ber:codeRelatierol> is hard coded: i.c. of hoofverzekerde 'HVZ' in case of medeverzekerde 'MVZ'.
Geslacht en datumGeboorte are taken form the table.
The element <ber:verzekerde> is obligatiry for hoofdverzekerde but optional for medeverzekerde: only in case geslacht_medeverzekerde and geboortedatum_medeverzekerde are not null this 2nd <ber:verzekerde> element has to be added.
I created the next SQL (I skipped some stuff in order to focus on the problem):
CREATE OR REPLACE
VIEW dps_v_berekening_berichten
AS
SELECT msg_id as msg_id
, XMLElement( "ber:berekening"
, XMLAttributes( 'http://www.w3.org/2001/XMLSchema-instance' AS "xmlns:xsi"
, 'http://www.mycompany.nl/berekenen' AS "xmlns:ber"

, xoa.geboortedatum_medeverzekerde AS "ber:datumGeboorte"
-- Some more elements.
) AS bericht
FROM DST_UP1_XML_OUTDATA xoa
The problem is that the XMLForest always creates an <ber:verzekerde> element for medeverzekerde. I tried to create an inline view with just the "vezekerde"attributes and conditionally joining this inline view with the dst_up1_xml_outdata table. That didn't solve my problem. Because in case of a medeverzekerde available it returned two XML documenst: one that included the hoofdverzekerde and one that included the medeverzekerde. And obviously that's not what I want.
I imagine I have to juggle with some of these SQL / XML functions although I cannot put the finger on the exact differences between some of these (XMLElement, XMLForest, XMLAgg, XMLSequence). The examples shown in de XML DB Developer's Guide don't seem to adress my problem.
Help !

Hi, are you talking about this part that you don't want to be there? I am not so clear about your requirements.
XMLElement( "ber:verzekerde"
, XMLForest ( 'MVZ' AS "ber:codeRelatierol"
, xoa.geslacht_medeverzekerde AS "ber:geslacht"
, xoa.geboortedatum_medeverzekerde AS "ber:datumGeboorte"
If you want to control certain subelements so they don't appear, do not use xmlforest. Use xmlelement instead so it is easier to control it using case when. Mark (of Oracle, he should be here soon since OOW is over) showed me this technique and it helps tremendously, because oftentimes XDB will return an empty tag even though your consumers don't like it!
try something like this,
(case when xoa.geboortedatum_medeverzekerde = 'MVZ' then
xmlelement("ber:verzekerde",
xmlelement("What you want", colname),
xmlelement("ber:codeRelatierol", 'MVZ'),
(case when colname is not null or = some other value then
xmlelement("Rest", colname))
end)
end),
You may have to twig some details there. But the key is to use the case when construct to get rid of unwanted elements or empty elements. So you should only have the elements if you have a value of 'MVZ'. Hope this helps.

Unable to get callback from Asynchronous BPEL process to work (AXIS Client)

Hello,
I am calling an Asynchronous BPEL process from an AXIS client, and I am unable to get the callback functionality to work. The AXIS client code has been generated from WSDL2Java using the BPEL process' WSDL file.
I CAN insert an invoke node in the BPEL process and invoke my Callback web service using that, but obviously that means the BPEL process is limited to only responding to one pre-determined client, which won't work.
My questions:
- How does the BPEL process know what endpoint to use to make the callback?
- Do I need to modify the generated code to create a SOAP Envelope and invoke the process with the envelope, intead of the invokeOneWay call?
- If I do need to create a SOAP Envelope with a replyto element, what is the structure of a typical BPEL envelope? Is there an example somewhere?
I have looked at the examples in the interop directory, specifically the AXIS calling Async BPEL, but I would like to try to keep the client code as independent as possible (I don't really want to have a dependency on the OTN library).
Any help would be greatly appreciated!!
Thank you.
-Ryan

Please have a look at the Binding in the WSDL. Axis must provide the ReplyTo and
MessageId information there. As far as I see, this must be done by an Axis-Handler,
because the Binding-Part in not generated by WSDL2Java.
I was able to generate the JavaClasses by using the "WSDL2Java -a" option, but
I still do not see how to use them in a handler and how to register the handler.
Maybe someone can give me a hint.

Execute oracle stored procedure from C# always returns null

Hi,
I'm trying to execute a stored procedure on oracle 9i. I'm using .Net OracleClient provider.
Apparently, I can execute the stored procedure, but it always returns null as a result (actually all the sp's I have there returns null)! I can execute any text statement against the database successfully, and also I can execute the stored procedure using Toad.
This is not the first time for me to call an oracle stored procedure, but this really is giving me a hard time! Can anyone help please?
Below are the SP, and the code used from .Net to call it, if that can help.
Oracle SP:
CREATE OR REPLACE PROCEDURE APIECARE.CHECK_EXISTENCE(l_number IN NUMBER) AS
v_status VARCHAR2(5) := NULL;
BEGIN
BEGIN
SELECT CHECK_NO_EXISTENCE(to_char(l_number))
INTO v_status
FROM DUAL;
EXCEPTION WHEN OTHERS THEN
v_status := NULL;
END;
DBMS_OUTPUT.PUT_LINE(v_status);
END CHECK_CONTRNO_EXISTENCE;
C# Code:
string connStr = "Data Source=datasource;Persist Security Info=True;User ID=user;Password=pass;Unicode=True";
OracleConnection conn = new OracleConnection(connStr);
OracleParameter param1 = new OracleParameter();
param1.ParameterName = "v_status";
param1.OracleType = OracleType.VarChar;
param1.Size = 5;
param1.Direction = ParameterDirection.Input;
OracleParameter param2 = new OracleParameter();
param2.ParameterName = "l_number";
param2.OracleType = OracleType.Number;
param2.Direction = ParameterDirection.Input;
param2.Value = 006550249;
OracleParameter[] oraParams = new OracleParameter[] { param1, param2 };
OracleCommand cmd = new OracleCommand("CHECK_EXISTENCE", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddRange(oraParams);
conn.Open();
object result = cmd.ExecuteScalar();
conn.Close();

Hi,
Does that actually execute? You're passing two parameters to a procedure that only takews 1 and get no error?
Your stored procedure doesnt return anything and has no output parameters, what are you expecting to be returned exactly?
If you're trying to access V_STATUS you'll need to declare that as either an output parameter of the procedure, or return value of the function, and also access it via accessing Param.Value, not as the result of ExecuteScalar.
See if this helps.
Cheers,
Greg

Select query on table rcv_lots_interface is always returning null

Hi ,
I need a help on the below issue.
The issue is after creating PO in Oracle 11i I receive it in MSCA application.
When we receive it at that point data gets inserted in the table " rcv_transactions_interface " and we have written a trigger on it.
From the trigger on table " rcv_transactions_interface " we are calling a package and in the package we have select query on "rcv_lots_interface."
But the select query is always returning null even though we are passing the correct "interface_transaction_id " and also after the "Receiving Transaction Processor" is executed i can see data in the table " RCV_LOT_TRANSACTIONS " for the same transaction.

Based on reviewing them the workarounds range from dropping the index to setting "_disable_function_based_index" to TRUE.Facinating. It seems to me that if you use the undocumented intitialization parameter you might just as well drop the FBIs too.
Another hazard of FBIs is the Law of Unintended Consequences. 2 years ago we tried to use one to speed up a query in a PL/SQL package. Worked OK for that purpose, but an unrelated loader on the affected table ran and rand but never finished until the FBI was dropped.

Output parameters always return null when ExecuteNonQuery - No RefCursor

I am trying to call a procedure through ODP that passes in one input parameter and returns two (non-RefCursor) VARCHAR2 output parameters. I am calling the procedure using ExecuteNonQuery(); however, my parameters always return null. When I run the procedure outside of ODP, such as with SQLPlus or SQL Navigator, the output parameters are populated correctly. For some reason, there appears to be a disconnect inside of ODP. Is there a way to resolve this?
Anyone have this problem?
Here is the basic code:
===========================================================
//     External call of the class below
DBNonCursorParameterTest Tester = new DBNonCursorParameterTest();

          if (conn.State != ConnectionState.Closed)
               conn.Close();
=========================================================
Other things to note:
I have no problems with returning RefCursors; they work fine. I just don't want to use RefCursors when they are not efficient, and I want to have the ability to return output parameters when I only want to return single values and/or a value from an insert/update/delete.
Thanks for any help you can provide.

Hello,
Here's a short test using multiple out parameters and a stored procedure. Does this work as expected in your environment?
Database:
/* simple procedure to return multiple out parameters */
create or replace procedure out_test (p_text in varchar2,
                                      p_upper out varchar2,
                                      p_initcap out varchar2)
as
begin
select upper(p_text) into p_upper from dual;
select initcap(p_text) into p_initcap from dual;
end;

UCCX XPath on Get XML Document Data Step always returns null

Hello,
Can someone tell whats wrong with my XPath, because it always returns null. I have tried different variations and nothing. I'm using UCCX 7.0
XML
<?xml version="1.0" encoding="utf-8" ?>
<GetManagersResult xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.labdomain.com/">
<ClaimManagersList>
    <X_CLAIM_MANAGER>
      <ClaimManagerUserName>test</ClaimManagerUserName>
    </X_CLAIM_MANAGER>
</ClaimManagersList>
</GetManagersResult>
XPATH
"/descendant::GetManagersResult/child::ClaimManagersList/child::X_CLAIM_MANAGER/child::ClaimManagerUserName"
During debug, this is the value of the xml document when it reaches the Get XML Document Data step:
TEXT[<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n<GetManagersResult xmlns=\"http://www.labdomain.com/\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">\r\n <ClaimManagersList>\r\n    <X_CLAIM_MANAGER>\r\n      <ClaimManagerUserName>test</ClaimManagerUserName>\r\n    </X_CLAIM_MANAGER>\r\n </ClaimManagersList>\r\n</GetManagersResult>]

It's your XML namespace in the root element.
First off, I have never seen the CRS Editor play nice when XML namespaces are involved.
Secondly, with your namespace in place, not even a generic xpath expression tester can find your data. See attachements.
I think that if you find a way to either: not send, or remove the namespace from your document, your xpath expression will work.

Request.getParameter() always returns null

I have a html file and am trying to retrieve the values from a formin my servlet.
here is the html code:
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<h1><b>Add DVD</b></h1>
</head>
<body>
<form action="add_dvd.do" method="POST">
Title:<input type="text" name="title" />
Year:<input type="text" name="year" />
Genre: <select name='gselected'>
<option value='Sci-Fi'>Sci-Fi</option>
</select>
or enter new genre:<input type="text" name='gentered' value="" />
<input type="submit" value="Add DVD" />
</form>
</body>
</html>
and here is the servlet code:
public class AddDVDServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// System.out.println("in AddDVDServlet post method");
List errorMsgs = new LinkedList();
//retrieve form parameters
try{
String title = request.getParameter("title").trim();
String year = request.getParameter("year").trim();
*String gentered = request.getParameter("gentered");
String gselected = request.getParameter("gselected");
String genre="";
if("".equals(gentered))
genre = gselected;
else
genre = gentered;
// System.out.println("parameter retrieved");
if(!year.matches("\\d\\d\\d\\d"))
// System.out.println("year not 4 digit long");
errorMsgs.add("Year must be four digit long");
if("".equals(title))
// System.out.println("title not entered");
errorMsgs.add("Please enter the title of the dvd");
if("".equals(genre))
// System.out.println("genre not valid");zdf
errorMsgs.add("Enter genre.");
if(! errorMsgs.isEmpty())
//System.out.println("errors in entry ");
request.setAttribute("errors",errorMsgs);
// System.out.println("error attribute set in request");
RequestDispatcher rd = request.getRequestDispatcher("error.view");
rd.forward(request, response);
return;
//create DVDItem instance
DVDItem dvd = new DVDItem(title,year,genre);
request.setAttribute("dvdItem",dvd);
RequestDispatcher rd = request.getRequestDispatcher("success.view");
rd.forward(request, response);
catch(Exception e){
errorMsgs.add(e.getMessage());
request.setAttribute("errors",errorMsgs);
RequestDispatcher rd = request.getRequestDispatcher("error.view");
rd.forward(request, response);
e.printStackTrace();
System.out.println("exception:"+e);
why does getParameter always return null??? whats wrong?

I don't know. However, I suspect that because you have a tag with the same name as 'title', its causing a name conflict. Chnage the name to something else. If it works, then that's the likely explaination.

How can I create an element in the model node?

Hi, Experts,
I create a model node that name is containerNode in the contxt. Cadinility is: 1..n
I write the code in the method:
private String getDataForOutputTable( IWDNode wageTypePayslip, IWDNode containerNode ){
     String betrgSumStr = "";
     int index = 0;
     Vector containerVector = new Vector();
     int size = wageTypePayslip.size();
     IWDNodeElement element = containerNode.createElement();// The system report error when I run the application.
     BigDecimal betrgSum = new BigDecimal( 0 );
I try to create a element in the containerNode, But the system report error when I run the application.

Hi,
You need to execute the model before creating the element.

How to create dynamic elements in action of a view?

hi all,
I created 2 buttons dynamically in WdDoModifyView(). I created action1, and parameter for that action i.e, id of type string.
when i click on button1, some ui elements must be displayed.....
can anyone tell me how to dynamically add UI elements in onAction() of view.....
i wrote the following code to create & map dynamically in WdDoModifyView()........
if(firstTime)
    IWDButton b1=(IWDButton)view.createElement(IWDButton.class,"button1");
    b1.setText("Button1");
    IWDButton b2=(IWDButton)view.createElement(IWDButton.class,"button2");
    b2.setText("Button2");
    IWDTransparentContainer tc=(IWDTransparentContainer)view.getElement("RootUIElementContainer");
    tc.addChild(b1);
    tc.addChild(b2);
     IWDButton butt1 = (IWDButton)view.getElement("button1");
     IWDParameterMapping pm1a = butt1.mappingOfOnAction();
     pm1a.addParameter("id1","link1a");
     IWDButton butt2 = (IWDButton)view.getElement("button2");
     IWDParameterMapping pm1b = butt2.mappingOfOnAction();
     pm1b.addParameter("id1","link1b");
after writing this..... in onAction().........of view... i wrote like this...
if (id1.equals("link1a"))
else{
in the if & else condition, i have to create UI elements dynamically.
when i am trying to create Ui elements dynamically, but i am unable to create dynamically here.
pls give me suggestion how to proceed this
regards,
vila

Hi Vila,
Are you trying to create UI elements dynamically in the action? If yes then you won't be able to do so because you can only create UI elements dynamically in WDDoModifyView().
Always WDDoModifyView() would be called after your action. So, you can handle it as you want in your WDDoModifyView() itself.
But if you want that those elements should be created everytime when you fire an event then don't write it within if(firstTime) clause as this would be true only when WDDoModifyView() is called for the first time when the page intially loads.

Oracle Coherence 3.7.1, It's always creating a new cluster in linux m/c.

Hi ,
I am facing an issue with Oracle Coherence 3.7.1 in linux m/c , where it’s always creating a new cluster, even if I start a new member provided with same cluster name as argument. -Dtangosol.coherence.cluster=name
It’s not joining the existing cluster , it’s always creating a new cluster with same name in Linux m/c.
But when I tried the same thing in windows m/c , it working fine , even If I start N number cache server’s it joining the same cluster as one more member.
Please someone help me, why it’s always creating a new cluster in linux m/c with same name ? why new VM’s are not joining the existing cluster? , Is there anything extra setup I need to do for Linux m/c.
Thanks in Advance.

For unicast, you need to define the override file as under:
<?xml version='1.0'?>
<coherence>
     <cluster-config>
          <member-identity>
               <cluster-name system-property="tangosol.coherence.cluster">LPACache_cluster</cluster-name>
          </member-identity>
          <unicast-listener>
              <well-known-addresses>
               <socket-address id="1">
                   <address system-property="tangosol.coherence.wka1">coherence-node1-ip</address>
                   <port system-property="tangosol.coherence.wka1.port"> coherence-node1-port</port>
               </socket-address>
               <socket-address id="2">
                   <address system-property="tangosol.coherence.wka2"> coherence-node2-ip </address>
                   <port system-property="tangosol.coherence.wka2.port"> coherence-node2-port</port>
               </socket-address>
              </well-known-addresses>
          <port-auto-adjust system-property="tangosol.coherence.localport.adjust">false</port-auto-adjust>
          </unicast-listener>
     </cluster-config>
     <configurable-cache-factory-config>
           <class-name>com.tangosol.net.DefaultConfigurableCacheFactory</class-name>
           <init-params>
              <init-param>
                  <param-type>java.lang.String</param-type>
                  <param-value system-property="tangosol.coherence.cacheconfig">coherence-cache-config.xml</param-value>
              </init-param>
          </init-params>
    </configurable-cache-factory-config>
    <logging-config>
           <severity-level system-property="tangosol.coherence.log.level">5</severity-level>
           <character-limit system-property="tangosol.coherence.log.limit">0</character-limit>
    </logging-config>
</coherence>Use the property -Dtangosol.coherence.localhost=coherence-node1-ip and -Dtangosol.coherence.localport=coherence-node1-port for coherence server1 and -Dtangosol.coherence.localhost=coherence-node2-ip and -Dtangosol.coherence.localport=coherence-node2-port for Coherence server 2. Once you start the servers with these changes, you should not see the below message:
Group{Address=224.3.7.0, Port=37000, TTL=4}
