Tess4J on Tomcat

  • Anonymous - 2012-02-25

    I have some trouble on tess on a web application.

    Mi OS is WinXp and the application server is tomcat 6.

    In stand alone mode is all ok, but whene i try to perform a text recognition on tomcat i have this exception:
    at javax.imageio.spi.FilterIterator.next(ServiceRegistry.java:808)
    at javax.imageio.ImageIO$ImageWriterIterator.next(ImageIO.java:816)
    at javax.imageio.ImageIO$ImageWriterIterator.next(ImageIO.java:801)

    What can be the problem?
    I tried with jai_core.jar, jai_codec.jar, jai_imageio.jar both on {tomcat_home}/lib and WEB-INF/lib but i always go on exception.

    Help me!

    Thanks for the reply.

    I'm at very new on imageIO so I don't understand.
    What was wrong in that case?

    I think the final answer was this one:
    Finally it is working. I was not trasnferring(jars, tiff images etc) the files to solaries box in binary mode. So all the files were corrupted and JRE was not able to pickup the plugins.


    But, sorry I don't unterstand!
    Can you "translate" for me.

    Thanks again.

    That user seemed to have FTPed the files in text mode, hence corrupting the binary files.

    I'm not experienced with Tess4J on a web environment, but make sure the .jar files are in in the classpath.
