[Vizinyenyec]

Dear Team,

First time I download the commercial Spire.xls to Java jar accidental, but I don't id like buy, when the Price is too much for Me.
I download Free spire.xls jar, and change the commaercial jar for free jar.
My exception message:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalAccessError: class com.spire.xls.packages.sprRFA (in unnamed module @0x434eb931) cannot access class sun.security.action.GetPropertyAction (in module java.base) because module java.base does not export sun.security.action to unnamed module @0x434eb931

How can i fix it?

Best Regards

Hi,

Thanks for your inquiry.
May I know the JDK version in your project? Are you using JDK 17? If so, when you use free Spire.XLS for java, the issue does exist, our free spire.xls for java hasn’t been fully compatible with high JDK version yet, but it is supported by our latest commercial version. We are willing to provide a temporary license (one month free) to help you evaluate our commercial version better. If you want to continue using the free version, please downgrade your JDK version, such as JDK 8.

Sincerely,

Hi Vizinyenyec,

Thanks for sharing your code via email.
I know from your code that you use sheet.exportDataTable() function of our Spire.Xls, I did a test for the function using JDK 8, but I did not reproduce your issue. You can try our latest commercial version (Spire.XLS for Java 12.11.8 ), which does enhancements for features, and we only maintain our free version irregularly, or you can send us your full runnable project that can reproduce your issue for further investigation. Thanks for your assistance.
