Tess4J works standalone in 64 bit windows but does not work in Tomcat 7

Trying OCR with Tess4J and being able to make it work as a standalone application on 64-bit windows. I am using eclipse for the same thing. Now I am trying to create a war of the same code and deploy to Tomcat7 and call the api using a servlet. I am getting the following error.

     java.util.NoSuchElementException
javax.imageio.spi.FilterIterator.next(ServiceRegistry.java:808)
javax.imageio.ImageIO$ImageWriterIterator.next(ImageIO.java:816)

javax.servlet.http.HttpServlet.service(HttpServlet.java:722)

Any help would be greatly appreciated.

Make sure you have jai_imageio

in CLASSPATH

or in WEB-INF/lib

. Call ImageIO.scanForPlugins();

before calling doOCR

.
