Jcaptcha doesnt work in java 1.5

[Abhi Venu]

I have added jcaptcha in a jsp page. I compiled the prject using java 6. But when i create a project using java 5.It gives exception doesnt work. Bad version number in .class file

java.lang.UnsupportedClassVersionError: Bad version number in .class file. How this can be fixed.

I revereted bak to another jar it seems and old version now i am getting black and whit captcha.How can this be made into beautiful ones as in new version.

I use following code

// create the image with the text
BufferedImage bi = service.getImageChallengeForID(httpServletRequest.getSession(true).getId());





ServletOutputStream out = httpServletResponse.getOutputStream();




Thanks

You're using an older JVM to execute the code than you're using to compile it. Code compiled in Java 6 needs at least a Java 6 JVM - you can't run it on a Java 5 JVM.
