[jboss-user] [Installation, Configuration & DEPLOYMENT] - Re: NoSuchMethodError when accessing library class.

Which class is making this call (if you would have posted the full exception stack trace I would know this...)? Where did it get loaded from? Both the callee class, and the HSSFCell class, at compile time, agreed on the signature of the setCellValue() method or else the compiler would have complained. Thus one of those classes is now incorrect. Another possibility is that the JAR file is corrupted. Try using javap or a decompiler to view the signature for the setCellValue method.
