Re: [resolved] Error upon opening the project

Hi,
The conflict may be occur when you have used studio for a while. To avoid this conflict, my suggestion is that use JDK 1.6 instead of 1.7. Please see the related reference Forum 27952
Is there any error log which is located in <Talend Studio installation path>/workspace/.metadata/.log for Talend Open Studio Data Integration.
In addition, try this solution:
Please follows the steps as below to restore the items.
1. Backup the workspace.
2. Delete the workspace and restart the studio.
3. Import all items from the backup of workspace done in step1.

Re: [resolved] Error upon opening the project

Hi,
There is unknown conflict problem when you use JDK 1.7. It suggested that you should use JDK 1.6.
In addition, please pay more attention on these points:
1. set the java environment correctly.
2. Make sure there is no space and Illegal character in your installation path.
Your feedback will be appreciated.
Best regards

Hi,
Which solution do you used to resolve it? Could you share your experience with us? Downgrade JDK 1.7 into JDK1.6 or delete the workspace?
