"oracle.fabric.common.FabricException: oracle.mds.config.MDSConfigurationException: MDS-01330: unable to load MDS configuration document MDS-01329

Everything was working fine for me.I started my machine and started jdeveloper

i got following pop up message



I ignored it and started working on jdeveloper.

I created a simple process and tried to compile it and it gave me following error in jdeveloper


Error(8,61): Parse of component type files failed, check the adf-config.xml file : "oracle.fabric.common.FabricException: oracle.mds.config.MDSConfigurationException: MDS-01330: unable to load MDS configuration document

Well for me the reason was the combine process as shown in the pop up message.

This process was having some connection information to external MDS repository

which i was not having access currently.

I shudown my jdeveloper

Deleted the combine process and restarted my jdeveloper and it started working fine.
