Error when trying to start the demo app on tomcat : com.axelor.internal.javax.el.ELException: Unable to find ExpressionFactory of type: # Licensed to the Apache Software Foundation (ASF) under one or more

Hi,

What version of java and tomcat do you use ?
Moreover, can you check on browser dev tools what request is causing the issue ? You may also check the tomcat logs if there are some useful logs and report here.

Java 1.8
Tomcat 8.5 (Also tried on tomcat 9.0, same error)
Axelor Open Platform : 5.3

The error occured after login when the views are loading. after when I click on every link in the menu, I get this error message

Can you report here the tomcat logs ? This may help to check exactly where and when the error occurs.
Thx

I have the same problem.
“com.axelor.internal.javax.el.ELException: Unable to find ExpressionFactory of type: # Licensed to the Apache Software Foundation (ASF) under one or more”
I have installed Apache Tomcat 8.5.51 and jdk-8.0.242.08-hotspot

That seems to be an issue with Tomcat 8.5.51. Can’t say why for now, but rollback to 8.5.50 works fine.

I changed Tomcat 8.5.51 to Tomcat 8.5.50 and it worked. thanks

I also change tomcat to version 8.5.50 and it works… Thanks @p.belloy

Hello
I have the same problem in Tomcat 8.5.54
did you find a fix?

We just released 5.0.23, 5.2.6 and 5.3.1 that contains a fix for tomcat 8.5.51 issue caused by javax.el service discovery.
Tomcat 8.5.51 and higher should work fine now.

hi @p.belloy

Just note that this error still persists on Tomcat 9.0.34 with the last release (5.3.2), it works on Tomcat 9.0.26.

Regards
