[kapilashantha rajapaksha]

hi,

I'm using this code for setting packager .

GenericValidatingPackager packager1 = new GenericValidatingPackager();
        packager1.readFile("base1.xml");
        m.setPackager(packager1);


but i'm getting this error

I suspect something has been broken in your copy of base1.xml, or
perhaps your base1.xml file is not in your runtime directory and needs
further path qualification?

Have you adjusted the file at all?

Can you try qualify it's location on your file system more precisely to
the readFile call?

Your version of this code does not match mine, which version are you
using? As this seems to be 'test code', perhaps you could get the
latest version and try again (as well as my suggestions above)?

Perhaps we could improve the defensiveness of the
GenericValidatingPackager.readFile code (or the Exception thrown)
perhaps; but first let's see what you are doing wrong 8).

use :
ISOPackager packager=new GenericPackager(new FileInputStream("[path]/base1.xml"));
m.setPackager(packager);

Exactly. The GenericValidatingPackager was an old contribution poorly maintained, I've never used it myself, I validate the messages as a whole on the higher level. I wonder if we should set aside that code, probably in the compat_1_5_2 module...

[Jeronimo Paoletti]

Maybe you can create a new compat_1_6_x module to start droping new garbage without mixing it with old garbage :)

Good point. Garbage selection, I like it, looks like something a good citizen would do :)

hi,

I tried to this

ISOPackager packager=new GenericPackager(new FileInputStream("[path]/base1.

xml"));
m.setPackager(packager);

but get error,

org.jpos.iso.ISOException: org.xml.sax.SAXParseException: File "genericpackager.dtd" not found. (org.xml.sax.SAXParseException: File "genericpackager.dtd" not found.)

Actually,

genericpackager.dtd file in my project folder

Try something like this instead:
ISOPackager packager=new GenericPackager("[path]/base1.xml");

and see if that works...

Cheers,

hi kapila ,

make sure your genericpackager.dtd is on the same directory with base1.xml

[java jawa]

Sorry I forget when I look to my code I use new GenericPackager(filename) not new GeneriPackager(inputstream),
using inputstream doesn't parse *.dtd so I think GenericPackager(inputstream) should be removed.

[Alejandro Revilla]

Victor added an entity resolver (yesterday), so GenericPackager(InputStream) should work now if you use the proper DTD URL (so that the resolver can pick it from the classpath).

hi
Thanks a lot

ISOPackager packager=new GenericPackager("base1.xml");

this will work properly

im using jpos.1.5.0.jar

Kapila,
