Not able to convert EBCDIC to ASCII

[Nitendra Dhaked]

Hi fady,

I am able to generate xsd schema from cobol copybook but when trying to convert ebcdic data to ascii data it throws error. 

com.legstar.coxb.transform.HostTransformException: ConversionException for element:NopostReason Cobol name:NOPOST-REASON Reason:Host data last byte is not a valid packed decimal byte. Host data at offset 2=0xd9e2

at com.legstar.coxb.transform.AbstractHostToJavaTransformer.transform(AbstractHostToJavaTransformer.java:273)

at com.legstar.coxb.transform.AbstractHostToJavaTransformer.transform(AbstractHostToJavaTransformer.java:212)

at com.legstar.test.coxb.mainframe.bind.ReportTapeNonmonChangesTransformers.toJava(ReportTapeNonmonChangesTransformers.java:76)

at EBCDICTOASCII.testReadFile(EBCDICTOASCII.java:66)

at Test.main(Test.java:9)

following are the code snippet 

                   ReportTapeNonmonChangesTransformers tf = new ReportTapeNonmonChangesTransformers();

                   File fi = new File("/home/cloudera/Desktop/BE000711.08232013.145747.TXT"); 

                   byte[] buffer = new byte[10750];

                   ZosVariableFileInputStream fis = new ZosVariableFileInputStream(fi);

                   int processed = 0;

  

                    HostTransformStatus status = new HostTransformStatus();

                    while ((fis.read(buffer, processed)) != -1)

                    {

                    ReportTapeNonmonChanges rtapechanges = tf.toJava(buffer, status);

                    processed = status.getHostBytesProcessed();

                   System.out.print(rtapechanges.getRecCodeBytes().getRecCodeKey());

                   }

             

this gives error on comp3 field.

Could you check what is the exact problem. 

PFA for cobol copybook EBCDIC binary file and xsd schema file.

Your data does not match your copybook.

Looking into C:\Users\Fady\AppData\Local\Temp\BE000711.08232013.145747.TXT, the first bytes are:

 C8 C4 D9 E2 C3 E4 E2  

These are EBCDIC characters for  H  D  R  S  C  U  S 

You can check for yourself here: http://en.wikipedia.org/wiki/EBCDIC

Now, your copybook starts like this:

       01  REPORT-TAPE-NONMON-CHANGES.

           02  REC-CODE-BYTES.

               03  REC-CODE-KEY            PIC X.

               03  POST-NOPOST-KEY         PIC X.

               03  NOPOST-REASON VALUE +0  PIC S9(3)V    COMP-3.

This means that your data must contain something different from a character starting on the 3rd byte. But it contains character R then S and so forth. This is invalid for a COMP-3.

Hence the pretty explicit error message.

Hi fady,

could you check for this updated file, still i am getting same error.

Hi,

Were you able to figure out the issue.
