Hi 

I've been using the 1.4 UN EDIFACT classes for a while now and I am loving how easy it is with smooks to handle EDIFACT. 

Now however I have to support a new EDIFACT message d16a VERMAS. There is no d16a zip file available from the 
(btw. the link on the smooks page is dead)

I have just taken the last __modelset_definitions.xml file (attached) I could find (d09b) and edited the fields to be inline with the D16A spec.
I then configured the new message VERMAS (see attached).

My POM is this:

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

    <modelVersion>4.0.0</modelVersion>

    <parent>

        <groupId>org.milyn</groupId>

        <artifactId>smooks-examples</artifactId>

        <version>1.4</version> <!-- base pom version - do not remove this comment -->

    </parent>

    <name>Milyn Smooks D16A  - EJC - Model Gen</name>

                <version>1.4</version> <!-- base pom version - do not remove this comment -->

                <configuration>

                    <ediMappingFile>VERMAS.xml</ediMappingFile>

                    <packageName>com.locuslive.odyssey.edi.d16a.vermas.model</packageName>

                </configuration>

                <executions>

                    <execution><goals><goal>generate</goal></goals></execution>

                </executions>

            </plugin>

        </plugins>

    </build>


    <dependencies>

        <dependency>

            <groupId>org.milyn</groupId>

            <artifactId>milyn-smooks-ejc</artifactId>

            <version>${milyn.smooks.core.version}</version>

        </dependency>

    </dependencies>


</project>


That does create the EJC classes for VERMAS and a factory but it only does the actual message, not the interchange UNH ... UNT around it as with the other EDIFACT messages. How can I configure it to create a D16AInterchangeFactory?


Regards

Hi Immo.

So I think you need to create a few 2 modules. One for the mappings and one for the Java binding (built from the mappings). E.g. see https://github.com/smooks/unedifact/tree/master/d13a

Is this what you did?

Hi Tom,

no I don’t have the zip file for D16A only a PDF for the VERMAS message.

I’ve taken the __message_definitions.xml file from a D09B version and modified the segments that have changed and created the VERMAS.xml definition by hand.

Ah sorry, you said that.

Hmmm ... kinda scoobied without the .zip file. I think if it were me I'd run the build for one of the other versions that has the zip and see what it generates in terms of mapping files. Then I'd look and see if I could manually manipulate those for work for d16a.

Will try to compile it tomorrow.

Hi Tom,

I’ve tried to create the same structure as for the other EDIFACT releases (see attached zip) but smooks seems to have a problem parsing the D16A.zip file:

Caused by: org.milyn.ect.EdiParseException: Error parsing the Un/Edifact specification '/Users/immo/Documents/development/workspaces/git_rep/Odyssey_svn/datamodel/edi/unedifact-master/d16a/mapping/D16A.zip'.
at org.milyn.ect.ECTUnEdifactExecutor.execute(ECTUnEdifactExecutor.java:55)
at org.milyn.ect.maven.ECTMojo.execute(ECTMojo.java:68)
... 22 more
Caused by: org.milyn.ect.EdiParseException: Seems that we have a directory containing 0 parseable version inside: [].
 All messages:
[]
at org.milyn.ect.formats.unedifact.UnEdifactSpecificationReader.<init>(UnEdifactSpecificationReader.java:84)

at org.milyn.ect.ECTUnEdifactExecutor.execute(ECTUnEdifactExecutor.java:52)
... 23 more

I’ve tried to compile  D13A and that worked fine (but only when set to version 1.6).

Have you come across this problem before?


We are currently running version 1.4 as the rebuild EDIFACT files where only available for 1.4. 
What are the risks of upgrading to 1.6?

Ooops ... they must have changed the format of the zip. I think you'll need the help of Bard Langoy.

Hi Tom

somehow I have the feeling the d16a.zip file found here:
is not the version you normally use. It says Schema library version. http://www.unece.org/cefact/xml_schemas/index.html

On the normal download page there is no d16a:
