Java 6 Scripting API vs Rhino

Apologies if this isn't the right place for this question, but I can't see a more appropriate forum.
I have some classes that use the Mozilla Rhino API for invoking javascript, and I was planning to upgrade this to use the new javax.script classes in Java 6. However, there's one particular feature that seems to be missing.
In Rhino, you invoke JS functions through the Function class (See http://www.mozilla.org/rhino/apidocs/org/mozilla/javascript/Function.html). This has a method construct() which invokes a JS function that has been implemented as a constructor, and returns the new JS object.
I can't find an equivalent method in the javax.script API. Am I missing something? Or was this feature deliberately left out because the new API is designed to be more general purpose, and support langauges that don't have constructors?
Thanks,
Alasdair

If it was me I wouldn't get all excited just because it seems like the java API implements something that previously required a third party library.
I know that when initially the logging api showed up I thought log4j would never be needed again. That was until I actually looked at what the logging api provided. It wasn't close. So sticking with log4j was and still is by far the better choice.
Besides the actual API you might also note that as the first version that it is more likely to have bugs than a third party library that has been around for a while.

Problems with Java Scripting API

Hello Everyone!
Guys, I need help with Java scripting API. A problem is that I cannot understand how can I operate Java Object's fields and methods from the script language. I have chosen embedded javascript to work with. And I can get the fields and methods of in-box java classes (such as ArrayList for example), but I cannot work with methods and fields from my own classes!
Here is an example:
public class ScriptingExample {
    class MyClass {
        int myfield = 5;
        int getInt() {return 7;}
    public void runExample() {
        ScriptEngineManager mgr = new ScriptEngineManager();
        List<ScriptEngineFactory> factories = mgr.getEngineFactories();
        ScriptEngineManager factory = new ScriptEngineManager();
        ScriptEngine engine = factory.getEngineByName("JavaScript");
        MyClass mc = new MyClass();
        try{
            engine.put("mc", mc);
            engine.eval("print(mc.myfield); print(mc.getInt())"); // or engine.eval("print(mc.myfield)");
        } catch (Exception e) {e.printStackTrace();}
} If I run the code with the commented part it prints "undefined" instead of "5".
If I run the code as it is it prints error instead of "7":
undefinedjavax.script.ScriptException: sun.org.mozilla.javascript.internal.EcmaError: TypeError: Cannot find function getInt. (<Unknown source>#1) in <Unknown source> at line number 1

How can I fix it?

Guys,
please let me raise this topic because several new questions emerged.
(1) How can I get all the variables created inside my engine?
There are two kinds of variables: first kind is Java obejcts put inside the engine and second kind is the variables created in my script, such as 'var a = 4;'. How can I list all the variables of that two kinds?
(2) Is there is a way to make 'import static' to the engine? I dont want to write MyClass.MyEnum.MyEnumItem every time. Also, I cannot put the whole enum into the engine with engine.put("MyEnum", MyEnum); I can put only enum items separately: engine.put("MyEnum", MyEnum.EnumItemA);. Thats why I ask about static import.
(3) How can I cast engine variables back to java variables inside my java code?
Here is my example:
package mypackage;
import java.util.ArrayList;
import java.util.List;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineFactory;
import javax.script.ScriptEngineManager;
public class Main
     public static void main(String[] args) throws Exception
          ScriptEngineManager mgr = new ScriptEngineManager();
          List<ScriptEngineFactory> factories = mgr.getEngineFactories();
          ScriptEngineManager factory = new ScriptEngineManager();
          ScriptEngine engine = factory.getEngineByName("JavaScript");
          ArrayList<Double> myList = new ArrayList<Double>();
          myList.add(5.0);
          engine.put("MyList", myList);
          engine.eval("MyVar = MyList.get(0);");
          System.out.println((Double)engine.get("MyVar"));
}The result is:
Exception in thread "main" java.lang.ClassCastException: sun.org.mozilla.javascript.internal.NativeJavaObject cannot be cast to java.lang.Double
+     at mypackage.Main.main(Main.java:28)+
Is it possible to retrieve my Double java object from the engine?

Using XML file in Java script to create Google Map

Hello,
I work for a non-profit in San Diego as a GIS Specialist. I have had to teach myself about some scripting to create some dynamic maps, but I am still very limited in my skills, so I have had to explore the internet in order to discover various tutorials and examples that have led me on a positive path.
Right now I am working on a Google Mash-Up that will incorporate over 14,000 records, which will appear as separate markers that will have pop-up info bubbles with additional info inside (using html), once the marker is clicked.
Here is the XML script example that is used in the tutorial I am following:
<markers>
<marker lat="43.65654" lng="-79.90138" html="Some stuff to display in the<br>First Info Window"
label="Marker One" />
<marker lat="43.91892" lng="-78.89231" html="Some stuff to display in the<br>Second Info Window"
label="Marker Two" />
<marker lat="43.82589" lng="-79.10040" html="Some stuff to display in the<br>Third Info Window"
label="Marker Three" />
</markers>
...and this is how it looks when the file is retrieved by the java script and mapped: http://econym.googlepages.com/example_map3.htm
This is the java script that creates the Google Map. I have emboldened the section of the script that retrieves the data and parses it to create the markers:

The "Marker" variable instructs Google Maps to label the marker with a particular color. I will be so grateful to the person(s) that helps me get through this wall that I have been hitting for a long time. It's very difficult without having the luxury of peers who know about these types of issues.
Thank you!!

Here is the relationship: They both contain geographic coordinates that produce a point on a map. I will use the rest of the information in the second xml file (company name, address, link, etc.) to produce the information for the bubble that will pop up once the marker is clicked.
My problem is that I need to try to keep the second xml file in a relatively similar format, so the rest of my records will still be accepted. If I had a smaller amount of records I could place them directly into the javascript, but because there are so many records, I need to use an xml file that can be retrieved by the java script. I chose to use the second type of xml file because I can easily copy and past the 14,000+ records that are now in excel document.
After the xml issue is corrected I need to rework the javascript that is now emboldened so that it will read the new xml file correctly. I included the first xml file so that the readers will understand what type of xml format is currently being used to produce the markers in the tutorial map.

How to pass values to variables in WAD 7.0 using java script

Hi.,
My requirement is based on WAD 7.0.
The sales value has to displayed in WAD using graph with various chart types.
I have created variables for plant and material group in a query.
I have created drop down box for plant with all plants in it, check box for material group and a Submit button in WAD in FORM tag of HTML coding.
Once all the values are set in drop down box, checkbox and if the user clicks on submit button, the values has to captured by the variables for which I have created and the graph has to be aligned to the new values in variables.
Kindly help me how to use java script to get the values from FORM and pass it to variables.
Regards,
Selva

Hi Selva,
You do not need to use Javascript for this. Instead you can achieve this by using API Commands in WAD 7.0.
Please configure Action on the ButtonGroup webitem to use 'Commands'.
->Choose Command 'Set Variables Values / SET_VARIABLES_STATE' under Commands for Web Templates
->Set Display Variable Screen setting to OFF
->Choose Query Variable for Plant, Select Variable Type as 'Binding Type', Binding Type as 'Data Provider Selection', Data Provider as the one you have assigned to the Dropdown webitem, Characteristic as 0PLANT or as that assigned to the Dropdown webitem
->Repeat above steps for Query Variable Material Group
Now when you make a selection from the Dropdown webitems, the Chart output will change accordingly. Let me know if this helps.

Acrobat standard 9.0 error while enabling commets option using Java script object

I'm using the below java script code in my VB 6.0 application for enabling commets options in the PDF file
Dim oJSO As Object
Set oJSO = mPDDoc.GetJSObject
oJSO.Collab.showAnnotToolsWhenNoCollab = True
It is working fine till Acrobat 8.0. Now I'm trying with Acrobat 9.0 standard edition, it is throwing scripting error 'An unhandled Win32 exception occured in Acrobat.exe[308].
Can anyone suggest the way to enable 'comment' options in Acrobat Standard 9.0 using Java Script Object?
Thanks

I get much the same problem with VB6, Acrobat 9 Pro and WinXP SP3. When I single step the line:
oJSO.Collab.showAnnotToolsWhenNoCollab = True
in debug I go to the error handler for my Sub. Inspecting the VB Err object has Number = -2147417851 and Description = "Automation error
The server threw an exception." I get a Microsoft crash notice about Acrobat a short while later.
I've experimented with the JavaScript debugger in Acrobat and you can execute Collab.showAnnotToolsWhenNoCollab = True and reference the value of Collab.showAnnotToolsWhenNoCollab in the console. The problem appears only when accessing Acrobat Javascript through the Interapplication Communication API.
If anyone can help it would be appreciated. I tried Adobe's Acrobat support and they were no help at all.

Differnce between java script xml dom and Java Xml dom

Hi,
In my application For client side in Java Script for craetion of DOM MIcrosoft Activex object is used. USing that one they are buiidng DOM. And they are saving as XML. In server side i have to write one servlet which will parse that xml and i have to store in dynamic arrays.Which API is better for parsing XML in java.In util pacakge which class is better for storing dynamical values that means MAP,Hash Map,Hash table ??

in java, the java..xml.parsers package is generally used for parsing xml into a DOM. there are also sax and stax parsers available.
which class in java.util is better for storing stuff depends on what you need to do with the stuff. find a nice tutorial on java collections and then decide which one makes sense for what you need.

          compareValue = compareObj[f];
          while(j >=0 && compareValue > currentValue) {
               this.data[j+1] = this.data[j];
               j--;
               if (j >=0) {
                    compareObj = this.data[j];
                    compareValue = compareObj[f];
          this.data[j+1] = currentObj;
// clone() -- copies the contents of a Vector to another Vector returning the new Vector.
function clone() {
     var newVector = new Vector(this.size);
     for (var i=0; i<this.size; i++) {
          newVector.addElement(this.data[i]);
     return newVector;
// toString() -- returns a string rep. of the Vector
function toString() {
     var str = "Vector Object properties:\n" +
     "Increment: " + this.increment + "\n" +
     "Size: " + this.size + "\n" +
     "Elements:\n";
     for (var i=0; i<getSize(); i++) {
          for (var prop in this.data[i]) {
               var obj = this.data[i];
               str += "\tObject." + prop + " = " + obj[prop] + "\n";
     return str;
// overwriteElementAt() - overwrites the element with an object at the specific index.
function overwriteElementAt(obj, index) {
     this.data[index] = obj;
Now I have written this code .This code is written using API'sfunction getOptions(ctx)
var options="";
var subroles = ctx.getAdminRole().getAttributeMultiValue("CUSTOM10");
var v = new Vector(subroles);
options = v.getElementAt(0);
Now suppose the function getAttributeMultivalue is returning RoleA,RoleB
Now i want RoleA to be stored in getElementAt(0) and RoleB in getElementAt(1)
But with the above code i am getting RoleA,RoleB in getElementAt(0)

well the question is also about Vector class of JavaNo it is not you doofus. It is about JavaScript. Your question has fuck all to do with Java.
so I thought to post it here.That was a mistake.
any ways if you don't know java script or anything about vector class then you should not reply.I know about JavaScript.
I know about Vectors.
I will not tell you anything about JavaScript here.
I wouldn't tell you anything useful anyway because I have taken a personal dislike to you.

How to create two level dynamic list using JSP , Java Script and Oracle

I am new in JSP. And i am facing problem in creating two level dynamic list using JSP ,Java Script where the listdata will come from Oracle 10g express edition database. Is there any easy way in JSP that is available on in ASP.NET.
Plz response with details.

1) Learn JDBC API [http://java.sun.com/docs/books/tutorial/jdbc/index.html].
2) Create DAO class which contains JDBC code and do all SQL queries and returns or takes ID's or DTO objects.
3) Learn Servlet API [http://java.sun.com/javaee/5/docs/tutorial/doc/].
4) Create Servlet class which calls the DAO class, gets the list of DTO's as result, puts it as a request attribute and forwards the request to a JSP page.
5) Learn JSP and JSTL [http://java.sun.com/javaee/5/docs/tutorial/doc/]. Also learn HTML if you even don't know it.
6) Create JSP page which uses the JSTL c:forEach tag to access the list of DTO's and iterate over it and prints a HTML list out.
You don't need Javascript for this.

Java scripting for header,footer and combine PDF as package

Hi All,
1.How to add header and footer using scripting.
2.How can i combine 5 pdf files in to one pdf as PDF file package using Java Scripting.
Thanks
Mohamed Idris

Hi Lenonard,
Thanks for your reply, I am refering JavaScript for Acrobat API Reference, Version 8 document , but i could not find the right syntax for the above task.
I am sucessfull writing script for page label but not for insertion of page number in the footer section.
Regarding combining PDF files i could merge file and it comes as single PDF file not like assembeling pdf files as package.
Please let me know the syntax and if i am looking at not right documentation, please let me know the document name to refer.
Thanks again.

Business Objects Dashboard External HTML/JAVA Script Link - User Authentication Depolyment Q

<p>Hello,</p><p>I have a rather unstructured problem here and am relatively new to Business Objects Enterprise. </p><p>We have users who are authenticated through Business Objects. The login sets their access levels and permissions. In addition to the BO reports, we would also like to link through BO Dashboard a JAVA Script webpage.</p><p>The JAVA Script and Business Object software sits on the same webserver.</p><p><strong>The problem is that through BO Dashboard and also an external URL link we can only pass a static link (i.e. /some directory/some doc.html) and not a dynamic userid with the URL, which changes based on the user (i.e. /some directory/some doc.jsp?UID=user1).</strong></p><p>The solution might be to insert a Business Object API call that can determine the user who is currently logged in? Or, if there is some way around the static html link through Business Objects Dashboard?</p><p>Any ideas or thoughts would be deeply appreciated.</p><p>Thanks,</p><p>Joe</p>

Are you setting Business Objects up as an external application?
If so, what parameters are you using to set it up?
Based on the fact that you're seeing the basic auth dialog, you probably need to specify
that it's using basic auth -- not GET.
