java.lang.NoClassDefFoundError

[bizmut]

Hi,

I need help about this stupid error "java.lang.NoClassDefFoundError" that keeps annoying me.

Well, I have packed 6 .class files into javasci.jar file and add it to my Eclipse project as externel jar. Now, when I import this file (import javasci." and call one of its functions, Eclipse does not report me any error, but when I run my program/application tomcat throws me an "java.lang.NoClassDefFoundError" error saying that "java.lang.NoClassDefFoundError: javasci/SciString" like it cannot find a diffinition for the called function.

What can be the problem? Anyone?

Thanks!!!

Bye, Igor S

Tomcat needs to know where your classes are at runtime. Did you deploy the application?

[bizmut]

Yes I did, but still... :-(

Any idea what might be the problem? I imported javasci.jar as an external jar into Java Build Path, but I do not know where I must import or put javasci.dll file. Is this file nessecery? Maybe you're right, maybe something is wrong with tomcat itself. When you said that I need to "deploy" application, what did you mean?

Thanks for reply!
