Error in Jboss after upgrading to AutoVue server 20.2.2 from 20.1.0

Question

We've developed an integration to view the files using AutoVue server. At the first stage the integration we used AutoVue server 20.10 and the functionality works fine. After upgrading to AutoVue server 20.2.2 following error comes when accessing the URL http://<servername>:58080/ifs-autovue-connector/servlet/DMS. Please note that Jboss is the application server.

The errors is ClassNotFoundException. But we've not implemented the class ActionGetProperties. Instead propactions are used. Please help us to resolve this issue as our customers will be in trouble after the AutoVue upgrade.

Answer 1

I would assume you are using the new jars that come with the latest ISDK
and that you have read the documentation with the list of all the changes
so in order to known which configuration parameter is missing, you might need to trace it using a debugger
there is one parameter that is missing ie returning null and it is obviously a mandatory one
Also, you most defintively did not properly migrate you web app from 20.1 repo to the 20.2.3 repo as you have missing classes
com.ifs.autovueconnector.ActionGetProperties
so your class path is not properly up to date
that also is a deployment descriptor error
Please review you deployment descriptor and validate that your war is properly built
