Calling Packed java in application scopes

David Vu1 — Sun, 29 May 2016 07:41:42 GMT

Hi talent,

I rewrite a code which write in global to my application :
var globalMap = new Packages.java.util.HashMap();

But it reponse that :

Use of Packages calls is not permitted in scoped applications

Has anyone experienced it before?

Thanks,Hao Duong

Hi Hao,

Package calls have been deprecated since Calgary. They caused issues with developers making changes to the API since they were direct calls to explicit Java objects. Instead, we recommend using the GlideScriptable objects for the API. This may help, but really applies to Packages.com.glide (or Packages.com.snc or Packages.com.glideapp) calls.

GlideScriptable object name

You are making a Packages.java.util call. You might also look at this:

Using the Packages Call Removal Tool - ServiceNow Wiki

Keep a bookmark to this:

Packages Call Replacement Script Objects - ServiceNow Wiki

I seem to recall a feature in Helsinki that allowed you to upload "extensions" to the Java code. I'm looking for that information now and will post it here if I find it.

Thanks ctomasi so much.
I already run
Using the Packages Call Removal Tool - ServiceNow Wiki

But notthing change.

And my problem is a little different, The scripts could run in Global scopes but when i change it to my own scope (custom scope) it not run anymore?
I just think that is there some GlideScript could replace the Packages.java.util ?

Thanks again.

I will check with our developers and see what they say. Stay tuned.

Hi Hao,

Can you help me understand what you were trying to do with the Hashmap method? We may be able to find an alternative for you.

Hi ctomasi,
Firstly, I really appreciate your help in resolving the problem, ( I have already seen many videos by you, that's so great! Thanks again )

About my issue, I try to make call Hashmap method to used it in evaluators :

var evaluator = new GlideScopedEvaluator();

var gMap = new Packages.java.util.HashMap();

gMap.put("context", this);

evaluator.evaluateStringWithGlobals("(" + this.definition.setup + ").call(context)", gMap);

Thanks,

Hao:

Not sure what the answer is on this. I piled up onto the same problem when trying to implement java.lang.Object.

So, summation: It appears you will not be able to use java.<<anything>> inside of scoped apps.

I will let you know when/if I find a way around this roadblock.

Steven.

Hi Chuck, been awhile since you posted this, but I am running into the same problem as the OP. If we can't use the native Java HashMap in scoped applications, what do you suggest as an alternative?

Thanks!

I haven't gone through all the latest API calls lately... have you taken a look at GlideDigest? Let me know if you find anything useful there.

Hi,

Did you find any workaround as how we can use this for scoped applications?

Thanks.
