Using Java/JVM as a Scripting Component in C++

I've been doing some research into the JNI and had a couple questions. Specifically, what I'm looking for is the use of Java / the JVM as a scripting language for a C++ application. I'd like to combine the speed of C++ as the application's core with the versatility and ease of use of Java as a scripting backend. I'm wondering if anyone knew of any projects that utilized this approach that I may be able to use as a reference point. I've been evaluating other languages, such as Lua and Python, but although Java's syntax is probably a lot more verbose the style of code, I believe, is a lot more cleaner then these other languages. I appreciate any assistance or direction that anyone may offer, thanks!

Java in of itself would not normally be used in this way. Most standard VMs run class files not java source. So to use it as a script language you would have to create class files first. To use this methodology you must start by investigating dynamically compilation.
The newer Java API contains a script language (which is not itself java.) There are also other implementations which run on a java VM. BeanShell is one.

The binary code for the script is not found error for the Script component - SSIS 2012

Hi,
I'm implementing a SSIS 2012 pkg. For a data flow task, I'm using a Visual Basic 2010 script component with an Oracle input flow. For the script component I've an input column and I've created an output column. Inside the script code I've edited only inside
Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer).
The written code is:
If Year(Row.OFFDATAORI) < 1900 Then
Row.OFFDATAORIconv = CDate(CStr("1900" + "-" + Right("00" + CStr(Month(Row.OFFDATAORI)), 2) + "-" + Right("00" + CStr(DatePart(DateInterval.Day, Row.OFFDATAORI)), 2))
Else : Row.OFFDATAORIconv = Row.OFFDATAORI
End If
It is to note that OFFDATAORI isn't the name of the input column for the script component.
When I close the script component I've an error about "The binary code for the script is not found".
Any helps to me, please?
Thanks

Hi,
I've solved. There was a syntax error, a bit hidden.

I might not be understanding your question completely since you mention WAD and then Excel, but if you are asking how to get the key figure values using Javascript in WAD, you can go to the Dataprovider properties and enable 'Output Result Data'. This will embed an XML element into the HTML output that you can then parse using standard Javascript DOM navigation.
Hope this helps.

SSIS script component to use defined connection manager to load data from a Oracle

In SSIS script compoment, I can connect to oracle with hard-coded connectionstring:
OracleConnection conn;
conn = new OracleConnection();
conn.ConnectionString = "Data Source=XE;User ID=hr;Password=******";
however, when I defined an connection managers in the script compoment and call it as follows:
    IDTSConnectionManager100 connMgr;
    OracleConnection conn;
    public override void AcquireConnections(object Transaction)
        connMgr = this.Connections.MyADONETConnectionManager;

How to fetch Properties of all Survey Lists from site collection using Java Script in SharePoint 2013

Hi,
I am trying to fetch properties of all lists of "Survey Type" from my site collection in SharePoint 2013 using script editor web part. I am able to fetch properties of one list by mentioning its name explicitly in code but not all survey
list.
My task is to display Survey name , description ,Time created and URLs of all survey lists using java script in script editor web part.
And let me know , if there is any other OOB feature of SharePoint 2013 to achieve the same.
Here is the code :
<script src="http://code.jquery.com/jquery-1.10.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
SP.SOD.executeFunc('sp.js', 'SP.ClientContext', sharePointReady);
function sharePointReady() {
GetSurveyList();
function GetSurveyList() {
var spListTitle = " List Name";
var clientContext = new SP.ClientContext.get_current();
var oWeb = clientContext.get_web();
this.surveyList = oWeb.get_lists().getByTitle(spListTitle);
clientContext.load(surveyList);
clientContext.executeQueryAsync(Function.createDelegate(this, this.GetListProperties),Function.createDelegate(this, this.onFailure));
function GetListProperties() {
$("#SurveyList").text("");
var surveyTable = "<table border=1>";
surveyTable = surveyTable.concat("<tr><td>Survey Name</td>");
surveyTable = surveyTable.concat("<td>Survey Description</td>");
surveyTable = surveyTable.concat("<td>Time Created</td>");
surveyTable = surveyTable.concat("<tr><td>" + surveyList.get_title() + "</td>");
surveyTable = surveyTable.concat("<td>" + surveyList.get_description() + "</td>");
surveyTable = surveyTable.concat("<td>" + surveyList.get_created().format("MM/dd/yyyy hh:mm tt")+ "</td>");
surveyTable = surveyTable.concat("</table>");
$("#SurveyList").append(surveyTable);
function onFailure(sender, args) {
alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
</script>
<div id="SurveyList"></div>

How to pass parameters to a page invoked using java script.--- Very Urgent.

Hello,
I have an advanced Table in my page. In the first column there is a
messageChoice. In the second column there is link item.On the link item i have set the following value for destination uri.
javascript:var a=window.open('OA.jsp?page=/AutoSales/oracle/apps/per/auto/webui/AutoSurrogatesPG&retainAM=Y','a','height=500,width=900,status=yes,toolbar=no,menubar=no,location=no,resizable=yes,scrollbar=yes'); a.focus();
The user selects a value from the message choice and when he clicks on the link item, the value selected from the list should go to the new page invoked using java script as a parameter. I need the value selected from choice to generates few fields in the new page. I have preferred java script because i need the base page and a model window should open. I have tried using setForwardUrl() and setting '_blank' and new window for target frame property on the link item. But it isnt working. The new page is opening in the same window.
I have also tried putting the value in a session.
Please help with any kind of suggestions or solutions.
Thank you.

Uma,
You need to
- Have a PPR Action on the messageChoice (this would trigger a form submit to populate the underlying View Attribute)
- Either
- Retrive the value from the View Attribute in the pop-up page (as I could see that you are retaining the AM)
- Use a SPEL in the link (on the modal page) to use the value from the View Attribute as the parameter value (in the form ${oa.current.<ViewAttributeName>)

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.

Display pop ups in the jsp by using Java script

Hi
can any body say ,how to display pop ups in the jsp by using Java script ?

that's correct. You can use the below code for AJAX request.
<script type="text/javascript">
var httpObject = getHTTPObject();
//create XMLHttpRequest object
function getHTTPObject() {
     var xmlhttp;
     if (window.XMLHttpRequest) // if Mozilla, Safari etc
          xmlhttp = new XMLHttpRequest();
     else if (window.ActiveXObject){ // if IE
          try {
               xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
          catch ( e ){
               try{
                    xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
               catch ( e ){}
     return xmlhttp;
//define the function to send the request
function sendRequest(){
    var currDesc = document.getElementById("description").value;
    var URL = "manageMaintAction.do"; //action mapping in your struts-config
    var queryString = "currDesc="+escape(currDesc); //get the currDesc value in your action class like request.getParameter("currDesc")
    httpObject.open( "Post", URL, true );
    httpObject.onreadystatechange = cbFn;
    httpObject.setRequestHeader( "Content-Type", "application/x-www-form-urlencoded");
    httpObject.send(queryString);
//callback fn
function cbFn() {
    if (httpObject.readyState == 4)
         if (httpObject.status == 200)
          var result = httpObject.responseText;

Thank you for your reply. I was reading on the metalink that we could use the to call the java script from oracle Forms 10g (Doc ID 265863.1)

I tried it but it did not open the any window as it claims. Am I missing anything? Is there any IE related setting which I need to modify for the above to work?

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.

How to run SQL script file on Linux using Java ?

Hi,
I need to execute .sql file using java. I used following approach for this.

        String sqlPromptLines="";

Above code working appropriate on Windows but not on Linux.
is there any changes needed ?

Hi gimbal2,
about code
jTextArea1.setText(e1.getMessage());I am using this code so that the user will be prompted with a message rather than stack trace.
About the issue I am getting on linux i believe its because of following statement.
processBuilder = new ProcessBuilder("sqlplus",userName+"/"+password+"@"+databaseName, script_location); //ORACLERegards,
