java.lang.AbstractMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletCon text;)Ljavax/servlet/jsp/JspApplicationContext

I upgraded a test server to 4.0.2 and started the admin and I get this error.

java.lang.AbstractMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletCon text;)Ljavax/servlet/jsp/JspApplicationContext

What is wrong?

Which OS and Java version? On Debian\Ubuntu you should upgrade to Java 8 (yes, Oracle’s) for 4.0.2.

it is actually Windows platform. I used the installer with JRE so it should be a correct usable Java runtime

Ok, then another problem might be that Openfire was still running during the update (service not stopped maybe). Check /openfire/lib folder and see if all files in there are of the same modification date. If not, make sure you stop Openfire (stop the service if using it) and run the installer again.

I could not find a Openfire service running, but reinstalling did fix the problem :slight_smile: Thanx!
