I'm having trouble getting connected to oracle 10g databases with the latest version of SQL Developer, the original issue I was having I was able to find a lot of help solving. This issue was a message "no ocijdbc11 found", I have since done several different methods to try and remedy this problem. The most recent was suggested in https://kr.forums.oracle.com/forums/thread.jspa?threadID=644299&start=15&tstart=0 and that was to get ahold of the ocijdbc11.dll and copy it into my oracle 10g folder.
Since doing this the error message has changed to:
"Internal Error: Fetch error message failed! Vendor code 17001"
Does anyone know how to fix this error?

1) Download and install an 11g client. The latest version of SQL Developer requires an 11g client if you are using the thick/OCI driver.
2) Don't use the OCI driver. Tools > Preferences > Database > Advanced. UNcheck Use OCI/Thick Driver
I had the same error. What worked for me was going into Registry Editor and delete the NLS_LANG key, found under HKEY_LOCAL_MACHINE > SOFTWARE > ORACLE_HOME. Then closed and reopened SQL Developer and problem was gone.
