QR CODE GENERATION

I'm trying to generate a report with QR CODE (Jasper Studio default QR CODE) by Command Prompt, but it's returning the following error:

English:

For those of you with the same problem, I just downloaded the zxing-core library from java2 and it worked.

It's important to copy the .jar file to your Java directory: C:Program FilesJavajre1.8.0_351libext

Português:

Para os que estiverem com o mesmo problema, eu baixei a biblioteca zxing-core do java2 e funcionou.

É importante copiar o arquivo .jar para o diretório do java: C:Program FilesJavajre1.8.0_351libext
