Maximo JS automation script: "importPackage" is not defined

I'm attempting to use a JS script from Maximo 76 Scripting Features (PDF download).

importPackage(java.util)
importPackage(Packages.psdi.server)
var ctx = new HashMap();
ctx.put("url","http://localhost:7001/maximo/oslc/script/countryapi?_lid=wilson&_lpwd=wilson");
service.invokeScript("LIB_HTTPCLIENT",ctx);
var jsonResp = ctx.get("response");
var countries = JSON.parse(jsonResp);

When I execute the script I get this error:

ReferenceError: "importPackage" is not defined in <eval> at line number 1

Why am I getting this error?

Solution

  • Add this to the beginning of the script:

    load("nashorn:mozilla_compat.js");

    Details:

    From Automation Scripts: Compatibility with Maximo 7.6.1:

    ...the Rhino JavaScript engine was replaced with Nashorn (V8). It turns out that Nashorn does not permit the import of whole Java packages which sheds light on why I was getting the error.

    Add the following line to the beginning of your script:

    load("nashorn:mozilla_compat.js");

    This article references how to properly construct your script to take advantage of the new script engine.

    And from Maximo 76 Scripting Features (PDF download).

    Java 8 and Nashorn engine:

    Some of the above example is written using the jdk 7 based rhino js engine. In jdk 1.8, the rhino engine has been replaced with the Nashorn (V8) engine. For example the importPackage command will not work there. You would need to use the JavaImporter function to do the same in Nashorn. You can look into this stackoverflow link for more details on what all changed from Rhino to Nashorn that may impact your script code in js:
