Failed to create delegate for component.

[Former Member]

Hi all,

I am facing a problem while deploying a local DC.Initilally the application is running fine.I changed the code (just a line) and deployed the application once again.It is throwing this error.

The initial exception that caused the request to fail, was:

java.lang.ClassNotFoundException: com.sasref.forms.wdp.InternalNCRFormComp -

Hi,

Are u using any child components from another DC project in ur project?

If yes, first build and deploy the DC project , which contains the child component , and then try to build and deploy the parent DC project.

let us know which line did you change? and where?

look at this thread

Hi,

Did you rebuild the project before deploying?

if problem persist... go to navigation view, expand your DC structure, delete gen_wdp, rebuild the DC and deploy.

Hi,

check inside the generated .ear file (usually at /gen/default/deploy). I expect that com/sasref/forms/wdp/InternalNCRFormComp.class is not there.

Did the "rebuild" give any error? and the "DC build"?
