Exception in thread “Main Thread” java.lang.NoClassDefFoundError: –XnoOpt | weblogic
I have seen many time while starting or setting up weblogic instances people see below error, so thought of posting it .
This error is a common mistake done while using the “-” symbol incorrectly.
Here in below error also you can see the noclassdeffound error is due to the invalid “–” character infront of XnoOpt
“-” is correct and “–” is wrong. change it and it will work. Similarly for other arguments also you might see the hipen issue so its better to retype the argument again in a notepad and copy paste to avoid the error.
