Just wasted a few hours of my life.
After this i can’t delete the duplicate entries in the console.
The outbound connection instance eis/DB/myDC in group javax.resource.cci.ConnectionFactory is defined explicitly in the applications deployment descriptors and may not be deleted via the console.
Content of the propertyfile :
|myds.eis=eis/DB/myDC | (without the pipelines)
At the end of the last row a space got added to the value of the ‘myds.eis’ property.
Result : invalid db adapter configuration 😉
