TinEye Reverse Image Search

TinEye Reverse Image Search

Tried this out today - you can upload an image, or provide an image URL and it will detect (using image recognition) where else in the web is the picture. It's quite remarkable and works quite well. I'm using it to track where students are copying images and diagrams from, without acknowledgements..

Now only if turnitin does the same thing for essays/reports ...

Bug in Helios - J2EE Module dependencies KAPUT!

Those idiots in charge of Eclipse WTP have done it again.

Apparently they have removed the J2EE module dependencies feature in Eclipse 3.6 Helios WTP 3.2.0

(see also: http://www.eclipse.org/forums/index.php?t=msg&th=172980&start=0&S=8e1b1230ca41777f3688d6396d0a2c58 )

What this means that if you have user libraries which your project will depend on (like.. say... JSTL or JDBC or something like that) normally under the old Galileo version you would:

1. Add a user library (or external jar or whatever) to the Java build path (Libraries -> Add External Jars).

2. Modify the J2EE Module Dependencies to export this (so it will get copied into the WEB-INF/lib directory or / depending on whether it's a WAR, JAR or EAR project)

Helios way:

They removed J2EE module dependencies, and now have a new feature called "Deployment Assembly" - which by itself looks interesting (directly map the source paths to deployment paths - this is goodness indeed). However, it forgets completely about the Java build path - ahem folks, how the F^*(^ do you mark the libraries to be exported to WEB-INF/lib ?? ooops... bbzzztt... epic fail.

Instead, you now rely on the Quickfix feature to fix it: See
Eclipse community forums /Web Tools Project (WTP)/tomcat and WTP: How to get dependent libraries into WEB-INF/lib
http://www.eclipse.org/forums/index.php?t=msg&goto=552136&S=60071956fefa1bb80b3a32ba65cd0f66

See also:
ClasspathEntriesPublishExportSupport - Eclipsepedia (http://wiki.eclipse.org/ClasspathEntriesPublishExportSupport)

Effectively, the missing libraries will appear due to the "Classpath dependency validator" which will indicate which libraries will be missing from the Webapp. You then select each miscreant and press QuickFix (Ctrl-1) to fix - ie: "Mark the associated raw classpath entry as a publish/export dependency"

(or the negative case: Exclude the associated raw classpath entry from the set of potential publish/export dependencies")

From what I gather, this is the ONLY way to do this until this bug is fixed.

The referenced bug may be fixed in Helios SR1: https://bugs.eclipse.org/bugs/show_bug.cgi?id=306462

Pain.

UPDATE: New way around this stupidity
Choose Deployment Assembly:
Click Add > Classpath Container > User Library > whatever
Now it will work. Geez!!
