How to create and object from an arrayList

Hi I want to create an object from an arrayList.

BillingQueryParam billingQueryParam = new BillingQueryParam();
/*This BillingQueryParam and billingItemManagerActionForm has getter and setter method for following attributes.
private int billingItemId;
private String[] paramName;
private String[] defaultParamValue;
List billingQueryParamList = new ArrayList();
for(int i = 0; i < billingItemManagerActionForm.getParamName().length; i++) {
     billingQueryParam.setParamName(billingItemManagerActionForm.getParamName());

     billingQueryParam = (BillingQueryParam)iter.next();
      System.out.println("****** BillingItemId-->"+billingQueryParam.getBillingItemId());
      System.out.println("****** Param Name-->"+billingQueryParam.getParamName()); //printing an array of paramName
      System.out.println("****** Default param value-->"+billingQueryParam.getDefaultParamValue());
}Here after iterating this list I want to create an object of billingQueryParam which contains a single value of itemId, paramName,paramTypeId and defaultParamName and I want to persist this object in database.
Please help...!!!

How to create value objects from xml

I am receiving xml back from my web service ( e4x ). I am
trying to figure out how to create a value object without having to
manually fetch each value in the value objects constructor. I am
using introspecton in my Java web service to do this. Is there such
a thing in Action Script?
Anyone done this before that can share some code???? Any help
would be very much appreciated.

That's twice now I've heard that. lol.
I am using Cairngorm and I suppose out of ignorance perhaps,
I am using VO's. So my web service would return an Object Proxy and
I have some code that could create objects dynamically from the
results. The objects had to be simple of course and now they are
becoming more complex thus the need to change to e4x instead of
objects.
So now I am trying to convert the xml result into the desired
VO to be used throughout the rest of the application. I'm not sure
how to use Cairngorm without the VO's they are tied to everything.
Are you familiar with the architecture? Your thoughts?

How to creat COM object from dll file?

Hi,
I tried to read about this topyc, but I didn't found eny example that creat
COM object. I downloaded jacob.jar
then I writed:
ActiveXComponent ax = new ActiveXComponent("C:/MyJava/deploy/SMSCom.dll");
Object SMSObj = ax.getObject();
I get error (I put jacob.jar with all athers jars, I don't know way this erre)
Exception occurred during event dispatching:
java.lang.UnsatisfiedLinkError: no jacob in java.library.path
     at java.lang.ClassLoader.loadLibrary(Unknown Source)
     at java.lang.Runtime.loadLibrary0(Unknown Source)
     at java.lang.System.loadLibrary(Unknown Source)
     at com.jacob.com.Dispatch.<clinit>(Dispatch.java)file name: SMSCom.dll

In VB this is the code:
Object SMSObj = CreateObject("SMSCom.SMSSender");
SMSObj.password = pass;

SMSObj.Source = phone;Thanks

In Eclipse:
1- To include jacob.jar for compile / run:
Choose the Java perspective, then in the Package Explorer right-click on the project and choose Properties.
Select Java Build Path from the left pane then the Librairies pane from the right.
Click on Add External Jars button and select the jacob.jar file then click Open then Ok.
2- To make jacob.dll and SMSCom.dll "visible" for run:
Open your Debug (or Run) Java application configuration (the one for your project's main class).
Select the Environment pane then click on Select button.
Select Path and click on Ok button.
Then re-select Path and click on Edit button.
Add the two appropriate folders for jacob.dll and SMSCom.dll in the Path and click on Ok then Apply.

How to create File object from InputStream

Hi everybody
Can I know a way to create a File object from InputStream object
Here's my code:
URL url = loader.getResource(xsdFile); //Thats a schema file..not to worry
InputStream istream = url.openStream();
Now from that 'istream' I need to build File object.
Thank you all

didn't know fileinputstream was made to read url objects ; in the doc, it just says "A FileInputStream obtains input bytes from a file in a file system." ; according to me, website is something outside the filesystem, but i could be wrong
edit: thought from the beginning it was all about FILEinputstream whereas it just says "inputstream" in the post ; my bad, it's still early in the morning here X)

How to create and exe from a class file.

I want to create an application and want to distribute it. I am using simplw awt gui interface. I have compiled the program and have got the required class file. If I want an executable how can I go for it.
There are many files provided by java library which are exe but are created using java API eg. policytool.exe. Please Help.
Ashwini Bagga,
Jaipur(Rajasthan)
INDIA.

Java uses the JVM to parse the class files. It cannot be converted to a .exe file
but if you want to distribute it, i suggest you use InstallAnywhere which makes it into an exe installer.
In the end it still uses the virtual machine...
If i am wrong anywhere pls correct me thanks...

How to create Activex object for my Visual C++ object

Hi,
I am working on development on Acrobat 9.0 SDK. I am facing problem is that I can compiled Visual C++ source code to an api. I can test functions on this api on Acrobat 9.0 windows, but I could not test it on IE web browser, because I don't know how to create Activex object from my Visual C++ source code or its api.
I read Acrobat 9 SDK document and found under C:\Acrobat 9 SDK\Version 1\PluginSupport\Tools\Visual Studio App Wizard has two files: Acro9PIWizInstaller.msi and setup.exe. I am not very sure those file are the key to help me to create Activex objects for my api. Are they the one I need to create Activex object? If not, could you please advise me how to create Activex object for my api or C++ codes.
Thanks a lot for any of your comments or advices.

Hi lrosenth,
Thanks a lot for your information.
My question is, on Javascript how do I call a function from .api. Below is my very simple test.
I got a function on BasicPlugin.cpp under C:\Acrobat 9 SDK\Version 1\PluginSupport\Samples\BasicPlugin. See below.
I added BasicPlugin.api on C:\Program Files\Adobe\Acrobat 9.0\Acrobat\plug_ins
     ACCB1 int ACCB2 MyPluginCommand() {
          int num = 5;
          return num;
On my HTML file, I create an <Object> below:
    <OBJECT id="acrobatapp"
            classid="clsid:85DE1C45-2C66-101B-B02E-04021C009402">
    </OBJECT>
    <OBJECT id="acrobatpdf"
            classid="clsid:CA8A9780-280D-11CF-A24D-444553540000"   >
        <Param name="SRC" value="http://www.adobe.com/devnet/acrobat/pdfs/acrobat_digital_signature_appearances_v9.pdf">
   </OBJECT>
On my Javascript. I call function MyPluginCommand() as below, but it is not working. How do I call function MyPluginCommand() on Javascript?
     var acrobatapp= document.getElementById("acrobatapp");
     var num= acrobatapp.MyPluginCommand();
     alert(num);
Thanks for your support,

How do I create an object from a filename?

I'm traversing directories and storing a list of files in a File array. Then I traverse the array looking at the extension of the file. If it is .java then I would like to instantiate it as a class so that I may pass the new object to another function which will examine its methods. I've tried Class.forName(file.getCanonicalPath()) and it throws a ClassNotFound exception. How can I create an object from a valid filename, please?

Rick_Avlonitis wrote:
If it is .java then I would like to </snip>.java files contain source code, they can't be "instantiated". Class.forName() takes a classname as parameter, i.e. "mypackage.MyClass". A class name is not a file name, and it doesn't have an extension. As stated in the other reply, you'll need to have the class on your class path.

How to create xml file from Oracle and sending the same xml file to an url

How to create xml file from Oracle and sending the same xml file to an url

SQL/XML (XMLElement, XMLForest, XMLAgg, etc) and UTL_HTTP.
Whether that works for you with the version of Oracle you have, your requirements, and needs is another story. A little detail goes a long way.

How to create and maintain a backup catalog, separate from default location, on and external HD

How to create and maintain a backup catalog on a separate hd - separate from default location of the catalog?

Simply copy the LR catalog backup file to another location. It’s quite small and only contains metadata e.g. your edit develop settings, keywords, captions, titles and camera exif data etc.
The LR backup does not physically copy your image files. So make sure you have a separate system backup for your photo files and folders.

How do I copy text and objects from pages to and paste into Email, objects don't show in Email

Anyone know how I copy text and objects from pages and paste into Email, objects don't show in Email, thanks

You can't expect Mail to support all the objects of Pages which can include anything up to charts generated from spreadsheet tables.
Even if Mail was a superset of Pages, what would the recipients who don't have either Mail or Pages, make of it?

How to create a object for IPageItemControlData?

how to create a object for IPageItemControlData?

From the header comment you'll see that IPageItemControlData is an Interface of PageItemWidget. That must've been an InDesign 1.0 or 1.5 feature predating kPageItemBoss, because except for the same comment even in InDesign 2.0 SDK the only further reference is a copy in the comment of its sibbling IFrameControlData which was removed with InDesign CS.
The IID and kPageItemControlDataImpl are probably only around because deep under the hood there must be some kind of conversion provider waiting to do its job on a very old document.
I guess the closest in today's functionality will be IHierarchy.

How to create an object alive all the time on a server side

Hi,
I work on an Intranet with J2EE technologies. I need an object to do several tasks in background on the server side. Like start scheduled processes on a database and files, stocked on the server. What is the way to do this. I thought to use the JNDI by declaring the object in the Deployement Descriptor, and to manage a timer within.
I don't know if this works.
Anyway, my question is how to create an object on the server that is ALIVE ALL THE TIME and visible by the other objects running in the same VM.
Thank's.

This may not be the correct design, but I had success doing the following:
1. Create an Stateless EJB that does a task, i.e. update a database table.
2. Create a subclass of java.util.TimerTask to call the EJB methods.
3. Kick off the TimerTask from a servlet.init method.
Seems to work pretty well to do scheduled tasks, such as refreshing lookup tables. I would imagine the same could be done with an MBean, but I haven't had time to fully understand JMX yet. (It's on the list).
As for event driven procedures, that can be done through a servlet interface.
You may also wish to review a scheduler here: http://www.part.net/quartz.html. Note, I have NOT even looked at it yet, so I have no clue if it's any good. But, it is on my list of tools to evaluate (that's a long list) someday when my head's above water. Have a look, and caveat emptor.
Hope this helps,
Perry Tew
