output parameter causing org.omg.CORBA.BAD_PARAM

Hi,

I'm having a problem with the valErrors out parameter in the following
IDL operation:

        boolean submit(in SMSProvExt::WorkOrderData wo,
            in boolean isNew,
            out string woName,
            out SMSProvExt::ValErrorList valErrors)
            raises(ApplError);

On the client side, I pass in the following value:

ValErrorListHolder valErrors = new ValErrorListHolder();

If the server implementation returns an empty list then everything
works fine:

public boolean submit(WorkOrderData wo, boolean isNew, StringHolder
woName, ValErrorListHolder valErrors) throws ApplError {

woName.value = "";

ValError[] errors = new ValError[0];
valErrors.value = errors;
return true;
}

However if the server implementation return a non-empty list, for
example:

public boolean submit(WorkOrderData wo, boolean isNew, StringHolder
woName, ValErrorListHolder valErrors) throws ApplError {

woName.value = "";

ValError[] errors = new ValError[1];

errors[0] = new ValError();
errors[0].valErrNo = 23;
errors[0].valErrMsg = "Some error";

valErrors.value = errors;
return true;
}

Then when the client calls submit(), the following exception is thrown:

org.omg.CORBA.BAD_PARAM: vmcid: 0x0 minor code: 0 completed: No

I'm using Visibroker, and both the client and server are implemented in
Java 5.
Thanks in advance for any suggestions!

What does the ValError class/struct look like? Are there any additional
attributes that aren't being initialized, besides valErrNo and
valErrMsg? I assume ValError is a struct?

Thanks for your reply. Yes, in the IDL file ValError is a struct that
looks like this:

 struct ValError {
 short valErrNo;
 string valErrMsg;
 long sorId;
 string vdtName;
 SDRTypeEnum sdrType;
 long sdrIndex;
 long sdrSubIndex;
 string vatName;
 string attrValue;
 NVList valErrorNVs;
 };

The .java file generated from this looks like this:

package surePay.idl2java.SMSProvExt;

/**
* <ul>
* <li> IDL Source
"C:/workspace/patrol/sure-pay/src/idl/SMSProvExt.idl"
* <li> IDL Name ::SMSProvExt::ValError
* <li> Repository Id IDL:SMSProvExt/ValError:1.0

* IDL definition:
* <pre>
* struct ValError {
...
};

You were right, the problem was caused by unininitialised attributes!

Much obliged!
