3 years ago Hello @kbodh : Is that the full error log? I haven't been able to recreate the issue, but do have a couple guesses for what's happening:
- I think 'AbstractMethodError' happens when an abstract method is called. Have you made any changes to the code? And are you packaging it as a .war file for Tomcat to run, or just running it through your IDE? If you're packaging it, how are you doing that? The package that Tomcat is running might be missing some files for some reason.
- Is there a reason you're using Tomcat 7 and not some newer version? I just tried running it with Tomcat 7 and encountered some different issues than what you have here, but I've run this and other samples using Tomcat 8 and 9 without issue so maybe the version of Tomcat is the problem.
Hi ,
I am deploying msal4jsample under Tomcat 7.0.107 using java 1.8. I am unable to start the application. Following is the error in the log. I have changed the file ms-identity-java-webapp/src/main/java/com.microsoft.azure.msalwebsample/MsalWebSampleApplication
and I decided not to use https so my application.properties has these entries along with tenant id and client id
