Thanks Jon

No I did not use the wizard.

I have not used that wizard before and not sure how to?

Could you advise where to find or what to search on?

Thank you

You didn't answer the question as to how you derived the prototypes. Did

you use the RDi wizard? If not, I would suggest trying that and comparing
the results with what you have - it has to be something relatively trivial.

Thanks Jon.

I think you may have identified where this is failing.

The code that is attempting to retrieve the results of the search is

not

returning anything although it does not generate an error.

resultJ = search(transGatewayJ: transReqJ);

I believe my problem is working out how to call what seems to be a

complex

method.

If we look at the signature for that method we have;

public com.braintreegateway.DateRangeNode authorizedAt();
Signature: ()Lcom/braintreegateway/DateRangeNode;

The prototypes for this are;

D transReqC PR O ExtProc(*JAVA:

D dateParams PR O ExtProc(*JAVA:

transReqJ = transReqC();
dateParamsJ = dateParams(transReqJ);
transreqJ = setRange(dateParamsJ: startJ: endJ);
transGatewayJ = transGateway(gateway);

// Retrieve the transactions

resultJ = search(transGatewayJ: transReqJ);

The java line of code that does this is;

TransactionSearchRequest request = new
TransactionSearchRequest().authorizedAt().between(start, end);

Here is the full java test program that does retrieve a transaction ...

package test;

import java.util.Calendar;
import java.util.List;

import com.braintreegateway.BraintreeGateway;
import com.braintreegateway.Environment;
import com.braintreegateway.ResourceCollection;
import com.braintreegateway.Transaction;
import com.braintreegateway.TransactionGateway;
import com.braintreegateway.TransactionSearchRequest;
import com.braintreegateway.exceptions.AuthenticationException;

public class BraintreeClient {

public BraintreeClient() {
// System.out.println("Obtain client token from

Braintree

...");
// String clientToken = gateway.clientToken().generate

();

// System.out.println("Client Token received:
"+clientToken);
try {
BraintreeGateway gateway = new
BraintreeGateway(Environment.SANDBOX, "hvcftg4259dkhjx8",
"pf5dy7b252n3hxhz",
"55e295ac1d16137f6ae6a2b267be3de3");
System.out.println(gateway.getConfiguration().getMerchantPath());
Calendar start = Calendar.getInstance();
start.set(Calendar.DATE, 3);
start.set(Calendar.MONTH, 0);
start.set(Calendar.YEAR, 2017);
start.set(Calendar.HOUR, 0);
start.set(Calendar.MINUTE, 0);
start.set(Calendar.SECOND, 0);
start.set(Calendar.MILLISECOND, 0);
System.out.println("start = " + start.getTime

());

Calendar end = Calendar.getInstance();
end.set(Calendar.DATE, 5);
end.set(Calendar.HOUR, 23);
System.out.println("end = " + end.getTime());
TransactionSearchRequest request = new
TransactionSearchRequest().authorizedAt().between(start, end);
ResourceCollection<Transaction> collection =
gateway.transaction().search(request);
TransactionGateway tg = gateway.transaction();
// getFirst
Transaction t = collection.getFirst();
System.out.println("First Transaction: id =
"+t.getId()+", amount = "+t.getAmount());
} catch (AuthenticationException e) {
e.printStackTrace();
}
}

public static void main(String[] args) {
new BraintreeClient();
}

}

When run the following is the output ...

/merchants/hvcftg4259dkhjx8

Without the whole thing I'm afraid I can't help much ... too many

unknowns

here. The fact that earlier method calls didn't blow up doesn't mean

they

worked! So all of the protos etc. need checking.

How did you create the prototypes? Using the RDi tooling?

One thing I did notice was that in the error messages you posted, many

of

the names are prefixed by a capital L. Is that a typo? or did they

really

paper that way in the log? for example shouldn't Ljava.util.List be
java.util.List ?

I posted this on the Midrange-L list and it was suggested I post it

I am hoping someone can point me in the right direction with this

one.

Java is crashing when I use a method that should return a java list
object..

I checked the class using the javap -s command in qsh I get the

details

about the class; (All class details from this are included below)

The method I am using is gstIds
public java.util.List getIds();
Signature: ()Ljava/util/List;

I have the prototype defined in my program as follows;

D getIds PR O ExtProc(*JAVA:
D 'com.braintreegateway.-
D ResourceCollection':'getIds')
D Class(*JAVA:'java.util.List')

D listIdJ S O Class(*JAVA:'java.util.List')

The following code snippet precedes the error but running in debug

all

statements complete normally

// Create search request
transReqJ = transReqC();
dateParamsJ = dateParams(transReqJ);
transreqJ = setRange(dateParamsJ: startJ: endJ);
transGatewayJ = transGateway(gateway);

// Retrieve the transactions
result = search(transGatewayJ: transReqJ);

When the following line is executed it results in a gpf and system

dump.

There is a stack trace showing on the screen but is meaningless to me

-

See below.

listIdJ = getIds(result);

The joblog shows error MSG:RNX0301 Java exception received when
