[ADF, JDev12.1.3] On deployment: weblogic.application.ModuleException: java.lang.UnsupportedClassVersionError

FlattitDec 27 2024 — edited Dec 27 2024

Hallo,

when I run my ADF application in JDev, its deployment fails due to this error:

weblogic.application.ModuleException: java.lang.UnsupportedClassVersionError: myapp/view/servlet/ShowPdfServlet : Unsupported major.minor version 52.0

I guess that this error starts to manifest after an automatic Java update.

C:\Program Files\Java

C:\Program Files (x86)\Java

I tried to uninistall the new Java versions unsupported by my JDev version but it didn't help.

Could you kindly help me to solve this problem?

Thanks
Federico
