Has anyone encountered the "invalid CEN header (bad signature)" error using FMSAv12 (126.96.36.1997) and more important, found a workaround?
Using my testing server (FMSA12 on my iMac), I attempted to upload 6 databases.
Launching the "Admin Console" from the web browser (localhost:16000) I got an "update Java" prompt.
This update installed OK. I didn't catch the version but I guess it is the Java 7 Update 11 advertised recently (see below).
Java Update (Version 7 Update 11) Addresses Security Vulnerability
ATTENTION: FileMaker Server 11 and 12, and FileMaker Server 11 and 12 Advanced users are advised to download and install this update. ISSUE: A vulnerability in Java 7, that can be exploited through web browsers on the Mac, has been reported. WORKAROUND: Oracle has released a Java update (Version 7 Update 11) to address this security concern. Download thisupdate
Visually inspecting the progress, the dialog box indicated that 5 of the 6 databases appeared to upload successfully.
The 6th database looked like it had completed uploading when the "invalid CEN header (bad signature)" dialog box appeared (see attachment).
As a result, 0 of the databases were actually uploaded (even the folder I created for the databases disappeared).
Quit the Admin Console, relaunched it from the web browser (localhost:16000).
This time I got a "Java version insecure" prompt (see attached screenshot).
The updater installed Java 7 Update 13 successfully.
Relaunched Admin Console from the web browser (localhost:16000).
Attempted to upload the 6 databases again and got to the "successfully uploaded" screen.
Closer inspection revealed:
(a) only 5 of the 6 databases had actually uploaded
(b) only 4 of the 5 uploaded databases were "Open". Not a big concern but 1 remained "closed" and had to be "opened" manually.
Finally, I attempted to upload the remaining (elusive) database.
Once again I got the "invalid CEN header (bad signature)" error.
Repeated attempts to upload the database consistently failed with the "invalid CEN header (bad signature)" error.
(a) restart the iMac (server). [FAIL]
(b) Save A Copy (compressed) of the database and attempt upload. [FAIL]
(c) crack open beer at 3 PM in the afternoon to calm my nerves. [SUCCESS]
If anyone else has encountered the "invalid CEN header (bad signature)" error using FMSAv12 (188.8.131.527) I am hoping you can respond with a possible workaround?
Thanks in advance.
