You will need to explain slowly and carefully what you want to do, and (this is important) why you want to do it. Right now, I have no idea what you need.

I am with Kimbert on this one.
I honestly have no idea what you have pasted, but from what I've gathered, is that what you're after?
| Code: |
DECLARE FILE_NAME CHARACTER;
SET FILE_NAME = 'Local Test' ||'.txt';
SET OutputLocalEnvironment.Destination.File.Name = FILE_NAME;

Sorry guys for the ambiguity..
My requirement was to unzip the zip files in JAVA , which I did. now in JCN i want to store the file names of the contents of zip file in local environment or any where in the output message to use it for further processing.. in JCN i have stored the file name in s...
| Code: |
while ((entry = zipStream.getNextEntry()) != null) {
String s = String.format("Entry: %s ",
entry.getName());
System.out.println(s);
int len= 0;
StringBuffer sb_result = new StringBuffer();
while ((len = zipStream.read(buffer)) > 0) {
sb_result.append(new String(buffer, 0, len));
}
zipStream.closeEntry();
String result = sb_result.toString();
file_num = file_num + 1;
MbElement root = outAssembly.getMessage().getRootElement();
msgBytes = result.getBytes();
msgBody = outMessage.getRootElement().createElementAsLastChildFromBitstream(msgBytes,"NONE", "", "", "", 0, 0, 0);
out.propagate(outAssembly);
msgBody.detach(); |

Thanks for explaining - I get the general idea now. But I still have questions.
Which of the following options are you trying to do:
a) pass a list of zip file entries to the remainder of the same message flow
or
b) pass a list of zip file entries to another message flow

| I am sending the unzipped files as blob to the same message flow for processing as the zip file contained an xml file and one pdf file . I need to do further processing on XML file. so in order to know which files has come out I am trying to store its name in local environment for routing. |

No, you didn't create anything yet. You just tried to access a non-existent element. |

Sounds like a long-winded way to do it. I don't understand why you need to put the filename into the LocalEnvironment. Is there any reason why you are not doing this:
- extract the XML file as as BLOB. Your loop is already doing that.
- parse the XML file using MbElement.createElementAsLastChildFromBitstream(...). Google will help you with the details.
- Allow the message tree to propagate onward to the downstream nodes in the flow.
One other point - if you know that the zip file contains exactly two entries then the while loop is probably not the best solution. Your code should extract each entry in turn, check that it is the expected type of entry, and complain if it gets unexpected input.
