Hi All,

I am trying to upgrade DFS which is on 6.7 to 21.4.

Is there any document that I can refer for this?

Also since the JAXB as changed in 21.4, will replacing the jars work? or I will have to recompile it again?

I tried with replacing the old jars with new 21.4 jars but I get the below error when I try to hit the service-

Caused by: java.lang.ClassCastException: class com.sun.xml.bind.v2.runtime.JAXBContextImpl cannot be cast to class com.sun.xml.bind.api.JAXBRIContext (com.sun.xml.bind.v2.runtime.JAXBContextImpl is in unnamed module of loader 'com.sun.xml.bind@2.3.3.b02-redhat-00001' @51e56376; com.sun.xml.bind.api.JAXBRIContext is in unnamed module of loader

Regards,

Deep

Are you actually upgrading DFS itself or you custom web services that is based on DFS? If its the former, why arent you downloading the latest version, of DFS from OpenText? If its the latter, after you download the latest version of DFS, test your custom web services against newer DFS and see what issues you have.

You shouldnt have to replace jars yourself.

Thanks for your reply.

We are using custom webservice that is based on DFS.

We have downloaded and trying to test with 21.4 DFS, but we get the following error -

Caused by: java.lang.ClassCastException: class com.sun.xml.bind.v2.runtime.JAXBContextImpl cannot be cast to class com.sun.xml.bind.api.JAXBRIContext (com.sun.xml.bind.v2.runtime.JAXBContextImpl is in unnamed module of loader 'com.sun.xml.bind@2.3.3.b02-redhat-00001' @3ae2dd55; com.sun.xml.bind.api.JAXBRIContext is in unnamed module of loader

This happens when we point to our new 21.4 repository but works fine with our old 16.4 env.

So it sounds like maybe JAXB interfaces have changed between 16.4 and 21.4. You will probably have to update your custom webservice code; I dont think this is issue with DFS code if you installed the latest version.
