Hi,

I keep getting this strange error when I try to run the atl project from the tutorial:
http://wiki.eclipse.org/ATL/Tutorials_-_Create_a_simple_ATL_ transformation

An internal error occurred during: "Launching Families2Persons".

java.lang.NullPointerException
at org.eclipse.debug.internal.core.LaunchConfiguration.getLaunchManager(LaunchConfiguration.java:461)
at org.eclipse.debug.internal.core.LaunchConfiguration.launch(LaunchConfiguration.java:863)
at org.eclipse.debug.internal.core.LaunchConfiguration.launch(LaunchConfiguration.java:702)
at org.eclipse.debug.internal.ui.DebugUIPlugin.buildAndLaunch(DebugUIPlugin.java:923)
at org.eclipse.debug.internal.ui.DebugUIPlugin$8.run(DebugUIPlugin.java:1126)
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)


this is the eclipse version information:
eclipse.buildId=I20100608-0911
java.version=1.6.0_18
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=de_DE
Framework arguments:  -product org.eclipse.epp.package.modeling.product
Command-line arguments:  -os linux -ws gtk -arch x86_64 -product org.eclipse.epp.package.modeling.product


Does anyone have any idea what could be wrong?

Thanx for some hints.

Cheers Björn


Now the error changed:

This is the Families.ecore:

this is the Persons.ecore:
<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0"

This is the Families2Persons.atl file:
module Families2Persons;

-- @path Families=/Families2Persons/Families.ecore
-- @path Persons=/Families2Persons/Persons.ecore

create OUT: Persons from IN: Families;

helper context Families!Member def: isFemale(): Boolean =
    if not self.familyMother.oclIsUndefined() then
        true
    else
        if not self.familyDaughter.oclIsUndefined() then
            true
        else
            false
        endif
    endif;

        else
            if not self.familySon.oclIsUndefined() then
                self.familySon.lastName
            else
                self.familyDaughter.lastName

    endif;

rule Member2Male {
    from
        s: Families!Member (not s.isFemale())
    to
        t: Persons!Male (
            fullName <- s.firstName + ' ' + s.familyName
        )
}


rule Member2Female {
    from
        s: Families!Member (s.isFemale())
    to
        t: Persons!Female (
            fullName <- s.firstName + ' ' + s.familyName
        )
}


and this is the sample-Families.xmi file:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns="Families">

        <mother firstName="Cindy"/>
        <sons firstName="Brandon"/>
        <daughters firstName="Brenda"/>
    </Family>
    <Family lastName="Sailor">
        <father firstName="Peter"/>
        <mother firstName="Jackie"/>
        <sons firstName="David"/>
        <sons firstName="Dylan"/>
        <daughters firstName="Kelly"/>
    </Family>
</xmi:XMI>


when trying to open the xmi file with the default-editor I keep getting this error:

Hi

ok here are the solutions:

1)
I changed the "sample-Families.xmi" to look like this:
<?xml version="1.0" encoding="UTF-8"?>
<Families:Family xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:Families="Families" lastName="asdf">
  <father firstName="qwer"/>
  <mother firstName="tzui"/>
  <sons firstName="ghjk"/>
  <daughters firstName="yxcv"/>
</Families:Family>


2)
then I had to register the two ecore metamodels: "Families.ecore" and "Persons.ecore" doing so with rightclick on the ecore file in the workspace and then selecting Register Metamodel.

3)
in the Personclass I forgot to set the type of "fullName" to EString.


The output I got was:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:Persons="Persons">
  <Persons:Male fullName="qwer asdf"/>
  <Persons:Male fullName="ghjk asdf"/>
  <Persons:Female fullName="tzui asdf"/>
  <Persons:Female fullName="yxcv asdf"/>
</xmi:XMI>
