EJBCA-CE: NoClassDefFoundError due to javax/servlet/Filter load failure

[goroyal]

I downloaded the EJBCA-CE with version 8_2_0_1_20231206, used ant deployear to deploy ejbca.ear to wildfly-34.0.0.Final.
Then I got the following error:

2024-11-13 16:19:46,331 WARN  [org.jboss.modules.define] (MSC service thread 1-6) Failed to define class org.ejbca.util.ServiceControlFilter in Module "deployment.ejbca.ear" from Service Module Loader: java.lang.NoClassDefFoundError: Failed to link org/ejbca/util/ServiceControlFilter (Module "deployment.ejbca.ear" from Service Module Loader): javax/servlet/Filter

There are still many other classes got NoClassDefFoundError due to javax/servlet/Filter or javax/servlet/Servlet.
How can I fix this kind of error? Thanks.

Please use the latest version of EJBCA. And read the installation pre-requisites and instructions here:
https://docs.keyfactor.com/ejbca/8.3.2/

If you are not used to java application server I can highly recommend the container deployment.

There is another guy got similar problem this year, but no answer either.
https://sourceforge.net/p/ejbca/discussion/132019/thread/f8035c9f77/

[primetomas]

He did get an answer, to post the question here. Which he did, and he got the answer here.

The answer is that pre-requisites for the EJBCA version you are trying to use is to use WildFly 26. WildFly 34 does jot work. And please use EJBCA 8.3.2 in stead of 8.2. How come you ended up with EJBCA 8.2.0.1 instead of the latest btw?

[goroyal]

The tag name style changed...thus I did not consider the r8.3.0-8.3.2 releases as the formal ones.
I tried EJBCA-CA r8.3.2 and use WildFly 26, following the document:

• https://docs.keyfactor.com/ejbca/8.3.2/application-servers
• https://docs.keyfactor.com/ejbca/8.3.2/wildfly-26
• https://docs.keyfactor.com/ejbca/8.3.2/deploying-ejbca

And now the "NoClassDefFoundError due to javax/servlet/Filter" problem does not exist. For the next step, I am going to research the configurations and setup the CAs according to docs.

Thank you very much!
