Can anybody give some advice?

Thanks.

JasperReports 5.x does not support JDK8. To use JDK8, you should upgrade to JasperReports 6.x

The other option is to downgrade to JDK7.

Hi hozawa

Thanks for your advice!

The only thing which I can not understand is sometimes it works OK, sometimes NOT.

And it happened on one linux server ,  but not happen on anther one.

ホザワさん

英語でよく伝われないかともいますので、すみませんが日本語で質問させてください。

JDKとJasperのバージョンがあってないことが了解しました。一点気になるところがありますが、

必ず再現できることではありません。また、一回も発生しない環境もあります。バージョンの差異であれば、

各環境も再現できると気がしますけど。

 

聞きたいですが、Jasper1.5 →Jasper1.6に更新すれば、APIのインタフェースが変わったことがありますか。

つまり、バージョンアップとともに、呼び出し元のソースを修正する必要がありますか。

 

お手数ですが、よろしくお願いします。

Hi every

Can anyone give me some advice?

It doesn't happen at everytime so I think maybe something wrong with memory.

I also get the same trouble after updating jasper's jar to jasperreport.-6.1.0.jar.
