I am trying to access the text values for field descriptors, but cannot
seem to do so. I have very little (essentially none) experience with
iSeries and RPG, and am trying to interface a Java program on top of
legacy code. I am using the Java code as below:
public static void main(String[] args) throws Exception {
AS400 system = new AS400();
final String PATH = "/QSYS.LIB/TMSV8DTA.LIB/CCAREF.FILE";
KeyedFile keyedFile = new KeyedFile(system, PATH);
AS400FileRecordDescription recordDescription = new
AS400FileRecordDescription(system, PATH);
RecordFormat[] format =
recordDescription.retrieveRecordFormat();
keyedFile.setRecordFormat(format[0]);
FieldDescription[] fieldDescriptions =
format[0].getFieldDescriptions();
for (FieldDescription fieldDescription :
fieldDescriptions) {
//I have also tried getCOLHDG() in addition to
getTEXT(); neither of these return any text.
System.out.println("Field '" +
fieldDescription.getFieldName() + "' = Text '" +
fieldDescription.getTEXT() + "'");
}
keyedFile.close();
system.disconnectAllServices();
System.exit(0);
}
}
I get results as follows:
Field 'DLCD24' = Text ''
Field 'TRIP24' = Text ''
Field 'BGDT24' = Text ''
....
I have confirmed that the file contains the correct field data. Below is
an excerpt from dspffd, run against the same file as I am accessing in
Java. Note that both Column Heading and Field Text are set (to "DELETE
CODE"):
Field Level Information
Data Field Buffer Buffer Field Column
Field Type Length Length Position Usage Heading
DLCD24 CHAR 1 1 1 Both DELETE
CODE
Field text . . . . . . . . . . . . . . . : DELETE CODE
Coded Character Set Identifier . . . . . : 37
In theory, when running my Java test, I should get the result:
Field 'DLCD24' = Text 'DELETE CODE'
Can anyone see what I may be doing wrong in my test Java class?
Thanks in advance for any and all help!
Cheers
