How to get the profile object in simple java class (Property accessor)

Hi All,
Please guide me how to get the profile object in simple java class (Property accessor) which is extending the RepositoryPropertyDescriptor.
I have one requirement where i need the profile object i.e i have store id which is tied to profile .so i need the profile object in the property accessor of the SKU item descriptor property, which is extending RepositoryPropertyDescriptor.
a.I dont have request object also to do request.resolvename.
b.It is not a component to create setter and getter.It is simple java class which is extending the RepositoryPropertyDescriptor.
Advance Thanks.

Iam afraid you might run into synchronization issues with it. You are trying to get/set value of property of a sku repository item that is shared across various profiles.
Say one profile A called setPropertyValue("propertyName", value).Now another profile B accesses
getPropertyValue() {
super.getPropertyValue() // Chance of getting value set by Profile A.
// Perform logic
There is a chance that profile B getting the value set by Profile A and hence inconsistency.
How about doing this way??
Create PropertyDescriptor in Profile (i.e user item descriptor), pass the attribute CustomCatalogTools in userProfile.xml to that property.
<attribute name="catalogTools" value="atg.commerce.catalog.CustomCatalogTools"/>
getPropertyValue()
//You have Profile item descriptor and also storeId property value.
// Use CustomCatalogTools.findSku();
// Use storeId, profile repository item, sku repository item to perform the logic
Here user itemdescriptor getPropertyValue/setPropertyValue is always called by same profile and there is consistency.

How i can make my own connection in java source of a jsp page

How i can make my own connection in java source of a jsp page (How to get connection from JNDI datasource address) ?
imagine that i have a rowset in a web page , now i want to do some operation using
plain JDBC , so i will need a connection object.
I tried to get one of my rowsets connection but it return null ?
what is best way to retrive a connection from JNDI datasource that we define for our project?
for example if i have
myRowSet.setDataSourceName("java:comp/env/jdbc/be");
in web page constructor
now i want a pure connection from the same datasource ? JNDI
Thank you

It is not hard to get your own connection from datasource.
in your case you need to do like the the following code.
i provide sample to show you how to catch the exception and create an statement .
Connection con =null;
try{
InitialContext ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/be");
con = ds.getConnection();
java.sql.Statement st =con.createStatement();
}catch(SQLException sqlex){
sqlex.printStackTrace();
sqlex.getNextException().printStackTrace();
catch(NamingException nex){
nex.printStackTrace();

Hi guys,
Im a newbie with arrays, just started really using them.. please bear with me if I don't seem to understand much..
I have a .txt file that contains either a square or rectangle (random width and length).. How can I read each line into a Java class into a 2D array with rows and columns?

Example :
import javax.swing.*;
import java.util.ArrayList;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.File;
public class ReadInto2DArrayExample {
    public static void main(String[] args) {

        try
            JFileChooser fileChooser = new JFileChooser();
            if (fileChooser.showOpenDialog(null) == JFileChooser.APPROVE_OPTION)
                File file = fileChooser.getSelectedFile();
                BufferedReader reader = new BufferedReader(new FileReader(file));
                String data;
                //Read from file
                while ((data = reader.readLine()) != null)

                reader.close();
                //Creating a 2D char array base on the array size
                twoDimesionArray = new char [array.size()][];
                //Convert array from ArrayList to 2D array
                for (int i = 0; i < array.size(); i++)
                    twoDimesionArray[i] = (char [])array.get(i);

How can i have a refrence of a java class object instance in my c++ project

Hi!
How can i have a refrence of a java class object instance in my c++ project. Is there a way?

hahaxia wrote:
The second question is the big one. The first question is half of the problem of "c++ to java" invocation and access. But the other half which is "java to c++ " invocation and access is still not solved. jni only provide the "java to c++ " DLL invocation Wrong,
Using JNI your java classes can have methods implemented in C/C++.
Using JNI you can call java classes.
There is no other possible interaction between C++ and java, so it does it all.

How to represent XML inline tags in a Java class

Dear all,
I am currently dealing with the issue of how to transform an XML document into a Java representation. As far as the strucural elements are concerned, I'd represent them each one of them as a Java class. However, the XML structure also allows for inline tags, i.e. elements which specify formatting information for the text. I am looking for good ideas for how to best represent these in my Java class(es).
Let's use an example. Suppose I have something like this:
<root>
   <structure>A piece of text</structure>
   <moreStructure>A piece of <b>bold</b> text</moreStructure>
   <finalStructure>A piece of <inlineTag att="value"> more text!</inlineTag>   </finalStructure>
</root>I this case I would build four classes for the strucural elements. But how do I represent <b> and <inlineTag>? In my XML documents I have several such inline tags, each of which may also have a bunch of attributes. I am sure this has been solved cleverly before. Any help greatly appreciated.
Best regards,
N.

The XML term for "containing tags and text" is "mixed content". And XML designers generally don't care much for mixed content. You're finding out one of the reasons for that right now. They aren't elegant or clever, just inconvenient.
However sometimes you have to deal with ugly structures. This is one of them. I would represent mixed content as a list, just as you already thought of. The elements in this list would be either text or elements. So in this example:<moreStructure>A piece of <b>bold</b> text</moreStructure>you would have three entries:
1. Text "A piece of "
2. A <b> element
3. Text " text"
And when retrieving from that list you would have to use "instanceof" to see if you had a String or an element of some kind.
And if "standalone tags" versus "paired tags" is a complication, then you're looking at it wrong. XML doesn't care much about tags. Tags only exist to delimit an element, and you should be looking at elements.
I'm guessing at your non-standard terminology here: a "standalone tag" is an empty element like
, right? And "paired tags" means a non-empty element like <this>that</this>? They're all elements. The first is a "br" element and the second is a "this" element.

How to pass an argument to a standalone java class in JDeveloper

To the experienced:
In JDeveloper when you write a java class with a main() method that takes no argument, you just right click the java file and select Run to run the program. But suppose the main() method takes arguments, how do you pass your arguments to the program? This is especially a problem as I use the studio version of JDeveloper (Versions 10.1.3.4 and 11.1.1.3) that each uses the version of JDK bundled with it, rather than the JDK (which is yet another different version) installed at the OS level of the PC.
Many thanks for your help!

Hi, Puthanampatti,
Suppose a java class has a main() method:
<pre>
public class FormatTerm {
public static void main(String[] args) {
String year = args[0];
String semester = args[1];
</pre>
What I want to know is how to pass the arguments when invoking FormatTerm within JDeveloper (i.e., without going out of JDeveloper to invoke FormatTerm on a command line in DOS). I would appreciate it very much if you know how to do that in JDeveloper 11g (I use Version 11.1.1.3) and could help me out.
Thank you very much for your help!

How to used a JCR Data Control in Java class?

Hi,
I created a JCR Data Control to my UCM to obtain a treeTable with the datas. But it's impossible to create a treeTable like i want to.
So I know how to create a treeModel to obtain the treeTable I want.
Is there a way to used the getItems method of the dataControl in a Java Class?
I tried this :
BindingContext bc = (BindingContext)JSFUtils.resolveExpression("#{data}");
DCDataControl dc = bc.findDataControl("UcmDC");
But dc is null.
There are some xml files (UcmDC.xml or getItems_return.xml). Is it a way to resolve my problem. And if so, how do I use?
Best regards,
Thomas
