to resolve this I have comment this code block in web.xml.

 <!--<context-param>

  <param-name>com.sun.faces.faceletCache</param-name>

  <param-value>oracle.adfinternal.view.faces.facelets.rich.MDSFaceletCache</param-value>

 </context-param>-->

But I want to know is there any alternate way to resolve this code without commenting on any existing code. If any jar to be added or any code block I can add to resolve this error.

As in your other question we need more information.

JDev version?

Information about the application?

When do you get this error?

....

I have migrated from 11.1.2.4 to 12.2.1.4 when I deploy my application from 12.2.1.4 JDeveloper it gives this error.

MDS exception when deploying in Jdev 12.2.1

as I followed this above solution from blog, to comment this code block but just wanted to know will I face any issue if I comment this block code / or it can be ignored by adding some code lines

The thread you mention tells you to purge the MDS data, not to comment out the block as you did. This info came from another user. I can't comment on this. You should try the other solution (purging the mds data).

And I still don't know what type of application we are talking about.

@Timo Hahn thanks for the help I am new to this technology. It would be really helpful if you could share any link on how to purging mds data as applicable is in my local only

Timo Hahn

It's all in the other post you mentioned yourself. I don't have anything else.
