Hi.  
I followed instructions on the page "git://gist.github.com/  
1043766.git".  
But I am getting following error.  
ClassCastException[in.vedantu.search.scripts.UserRelativeScript cannot  
be cast to org.elasticsearch.script.NativeScriptFactory

Does somebody know what the problem is?

Regards.

Yes.  
But I am not sure if my perception of binding classes into jar was  
correct.  
All I did was I took Script and ScriptFactory classes and put them in  
a new folder and ran following command.  
jar -cvf myjar.jar classfolder.  
Is this the correct way?

Caused by: java.lang.ClassCastException:  
in.vedantu.search.scripts.UserRelativeScript cannot be cast to  
org.elasticsearch.script.NativeScript_Factory_

Is this because you need to be specifying the Factory not the Script in your  
conf?

Yes.  
I guess that was the problem.  
Now the script is working fine.  
Thanks Paul.

Hi. There is another problem. Though it has nothing to do with above  
one.

I want to add parameters to my script.  
I referenced this document  
Passing parameters to native script : '[http://groups.google.com/a/](http://groups.google.com/a/)  
[elasticsearch.com/group/users/browse\_thread/thread/59b85fab8e35f1e3](http://elasticsearch.com/group/users/browse_thread/thread/59b85fab8e35f1e3)'

Now my ScriptFactory class became a factory that simply creates an  
AbstractFloatScript:  
The file is at git://gist.github.com/1073346.git.

Now I am getting following error.  
git://gist.github.com/1073348.git

Isn't this the right way to pass parameters?

Regards.

Well it looks like it can't find the nested ($1) class. Did you remake your  
jar correctly?

Yes. In the same way.  
I just wrote the factory class and did NOT write the script class.  
Instead I wrote my runAsFloat function in factory class itself.

public ExecutableScript newScript(final Map\<String, Object\> params) {  
return new AbstractFloatSearchScript() {

```
        @Override
        public float runAsFloat() {
           ///My function
        }
   };

```

}

The problem is still persisting. The same problem as I mentioned  
above.  
git://gist.github.com/1073348.git.

My jar file is constructed correctly. I am sure about that. Can there  
be any other reason for this?

Regards.
