获取java.lang.NoSuchMethodError

Question

am using jacob jar for calling a macro of excel sheet from java code..

final  ActiveXComponent excel = new ActiveXComponent("Excel.Application");
final Dispatch workbooks = excel.getProperty("Workbooks") .toDispatch();
final Dispatch workBook = Dispatch.call(workbooks, "Open", file.getAbsolutePath()).toDispatch(); 

com.jacob.com.Variant f = new com.jacob.com.Variant(true);
Dispatch.call(workBook, "Close", f);

and also am using maven to add all the jar dependency. but then i realised that i need to add the .DLL file then i added jacob jar manually and gave dll file in native library but now am getting

Exception in thread "main" java.lang.NoSuchMethodError: com.jacob.com.Dispatch.call(Lcom/jacob/com/Dispatch;Ljava/lang/String;Ljava/lang/Object;)Lcom/jacob/com/Variant;

Answer 1

This could mean that at runtime, the version of the jar you're using with com.jacob.com.Dispatch is different than the one com.common.getData was compiled against. It's telling you that the class com.jacob.com.Dispatch does exist but that it has no method named call that takes Dispatch, String, Object as arguments.

Are you perhaps compiling with one jar but running with another?
