Name required. Post was not sent - check your email addresses!This tutorial will present message flows, data elements values and meanings. If we imagine a generic message flow between 2 institutions regardless the scope, this can be captured in the following diagram. An authorization message is an approval or guarantee of funds given by the card issuer to the acquirer.
A financial presentment message can be used as a complete transaction: to transfer the money from one account to another. A financial accumulation presentment message completes the transactions, usually used in combination with an x message. A file action message is used to add, change, delete or replace a file or record or inquire into a file or perform card administration.
A reversal message is the partial or complete cancellation of the effects of a previous authorization xfinancial transaction xor financial transaction advice x that cannot be processed as instructed. A reversal advice message is a notification that the initial transaction failed. This can be an authorization x or financial transaction x A reconciliation message is the exchange of totals between two institutions. This can be done if the following steps:.
Depends on the message scope, some of the data elements are used more than the others. Here is a list of some of the most used data elements and the possible values. A number identifying the cardholder and the card issuer. If the field is missing and the message contains data element 35, the PAN can be read from there. Account Type Description 00 Default - unspecified 10 Savings account 20 Cheque account 30 Credit facility 40 Universal account 50 Investment account 60 Electronic purse card account.
The amount transaction field represents the funds requested by the cardholder in the local currency field A number assigned by a transaction originator to assist in identifying a transaction uniquely. The systems trace audit number remains unchanged for all messages within a transaction.
Contains the time local transaction in hhmmss format providing the time when the transaction takes place at the card acceptor location. Contains the date local transaction in MMDD format providing the date when the transaction takes place at the card acceptor location.
Is there a way to read cobol data in a Java program? More concretely I'm confronted with the following case:. I have a file with fixed length records of data.
The data definition is done as Cobol copybooks. What I think of is a library which taking into account the copybooks would be able to read those records. Ideally it should be possible to generate basic java classes and structures based on the copybook information. In a later step the datarecords would be parsed and the data filled into objects of those generated classes. Do you know a library providing this kind of functionality?Benzal gel versiones colores
Or any other techniques to cope with the problem of reading cobol data? There are some commercial tools which provide this functionality. They are, however, very expensive. Do you know any open-source alternative or a combination of different tools to provide the entire functionality? For example the cb2xml reads copybook structures and transforms them into xml.
A later step would be to generate a record reader based on the cb2xml xml information. Or to use a record reader which is configurable. Do you know a cobol record reader decoder?
See RecordEditor Code Generation notes for details. I have done that before. Here is a nice tutorial on how to access metada information with JDBC. Here is another one. In this regard, I also used an IBM native driver. Don't remember the name though. It was a long time ago. There appear to be some commercial solutions for this.
Alternatively you can use cb2xml to convert the copybooks to XML, and then import the XML into Java using whatever mechanism you require. I have used Bruce's JRecord from sourceforge package for my project. It took only couple of days to learn to use it and saved me months of work in rolling out a much less general solution on my own.
I recommend it highly.

Let us call the extended class JRecord. I also need that JObject instances can be easily cast to and from the extended type JRecord. The question is: how I take a JObject instance and cast it as my extended type which also inherits from JObjectin a way it keeps all its content but gets "dressed" with the extra properties when narrowing from JObject to JRecord and "striped" of those properties when widening from JRecord back to JObject?
Below is my first scratch and I omitted most of the properties because its string building is complex and irrelevant to the problem, which raises on both custom CType operators, where. NET tells me that. Conversion operators cannot convert from a type to its base type. Conversion operators cannot convert from a base type. So, what should I do?

Should I create a bare new instance and create children with the same content from those of the object I want to cast? I would not use inheritance and conversion operators in this case.
Instead, I would use composition here. In other words, make the JRecord class wrap the original JObject and delegate to it as needed. If you absolutely must use inheritance, because you want to pass the JRecord directly to other places in the application that expect only a JObjectyou could do this:. This is nearly the same thing, except now the JRecord is a JObject so you can pass it around freely. The tradeoff is that now it has to copy all the properties when the JRecord is first constructed.
We take advantage of JObject 's built-in copy constructor to do this. Learn more. Extend Newtonsoft. JObject Class Ask Question.

I am sending and recieving a products information from a server as a String, the server receive and send the price of the product in COBOLS s9 6 v99 format.
I am unable to convert the given decimal from or to this format in java. Note : Currently I have no implementation of the conversion,I am looking for a solution. Note: Even if you do not have the Full Cobol Copybook, you could set up a Cobol Copybook for this one field and still use a package. The copybook would be:. There is no one single Cobol Zoned Decimal format, it varies from compilere to Compiler and what the encoding is.
To decode Zoned Decimal you really need to know the. The encoding characterset used by the server determines how the sign digit is represented.
From what I can see it should be reasonably straightforward. This assumes, which seems to be the case from your example, that this is a Zoned Decimal. First you will need to get the sign of the number. Simply check the last character.
If it is a non-digit then it is negative assuming you are using F format for the positive number. Once you have that you can then replace that character with the correct, equivalent digit.
