Log window

JDeveloper didn't show log window


Search for the windowinglayout.xml. In my case it was found in:
~/jdevhome/system/oracle.ide.10.1.3.41.57

After renaming/deleting it, I could get my log window again.
One remark: jDeveloper saves the file after closure. So first close jDeveloper and then remove the file.
