Error on console, but it works



Hello, I got an error launching my jasper app from Java. Everithing works fine, but I have this stackstrace in my console:

Error instantiating extensions registry for queryexecuters.hive from jar:file:/C:/Users/Username/workspace/.metadata/.plugins/org.eclipse.wst.server.‌ ​ core/tmp3/wtpwebapps/MyAPP/WEB-INF/lib/js-hive-datasource-1.1.jar!/jasperrepo‌ ​

Why it can't find into the jar? Is there some bug inside the library?

The error doesn't seem to say that it cannot find It cannot instantiate the query executer. I guess the problem is more along the lines of some other dependency that is missing. You don't need js-hive-datasource-1.1.jar. Remove that and let us know if that fixes it.

@mdahlman It worked, thanks. Which are the minimum libraries to make a report in Java?

1 Answer:


If you aren't using Hadoop Hive, then consider removing js-hive-datasource-1.1.jar. Maybe that will solve your error.

@mdahlman I don't know if it is useful for me, I'm not so expert. I put all libraries in my project. Anyway, why that error inside the library? What is Hadoop Hive?
