How to access form objects from different class?
Hello, I am new to java and i started with netbeans 6 beta,
when i create java form application from template i get 2 classes one ends with APP and one with VIEW,
i put for example jTextField1 with the form designer to the form and i can manipulate it's contents easily from within it's class (let's say it is MyAppView).
Question>
How can i access jTextField1 value from different class that i created in the same project?
please help. and sorry for such newbie question.
Thanks Mike
hmm now it says
non static variable jTree1 can not be referenced from static context
My code in ClasWithFormObjects is
public static void setTreeModel (DefaultMutableTreeNode treemodel){
jTree1.setModel(new DefaultTreeModel(treemodel));
and in Class2 it is
ClasWithFormObjects.setTreeModel(model);

How to access the objects from multiple classes in ABAP Objects
<b> Give me The scenario and solution to the above problem </b>
In abap OO you can have only one super class.
multiple inheritence can be acheived by inheriting multiple interfaces.
abap OO is similler to that of JAVA in inheritence.
so you can not have classes a and b both as super at same time for a class.
however if still you want to acheive your perpose then you can do it using heirarchical inheritance where b inherits a and c inhrites b. so this way public methods will be accesible in c
do revert back if any other doubt.

How to access servlet objects from OA page controller class
Hi everybody!
I need to put some value into servlet attribute in OA page controller class to read it from ordinary servlet later.
How can i do it? Is it possible to get HttpServletRequest and HttpServletResponse objects from page controller?
Thank you.I have a servlet which receives uploaded files with special attributes (something like tags for file) using POST request.
This attributes created when user open page in standard OAF page via page controller.
On client side I have an applet which uploads user selected file to my servlet and passes this file attributes.
Now this attributes passes as plain text. I want to encrypt this attributes to hide attribute details from user. To do this I need to share some information between OAF page and my servlet.
I know that OAF supports URL encryption, but to decrypt it I should use standard pageContext object.
But in ordinary servlet I can't use it. -
How to Access MXML components from ActionScript class
Hi ,
I am having a Application Conataner , in which i am having a Form Container with some Label in it .
This is some thing similar to this as shown :
<Mx:Application>
<Mx:Form>
<Mx:Label text="Hello world"/>
</Mx:Form>
</Mx:Application>
Can any body please let me know how can i access this Form's Label , from an ActionScript class .
catch(error:*)
// Here i want to access these Objects and set data to that Label .
Basically My requirement is that iinside the catch block of my ActionScript class , i want to set some text to the Label , Please
let me know if this is possible or not also ??
Waiting for your Replies .Hi these both are not same these refer to different one...
Well let me explain...
Application.application.myCustomComp.myLabel.text = "sometext"; sets the label "myLabel" which is present inside your customcomponent(which is in main application).
Application.application.myLabel.text = "sometext"; sets the label "myLabel" which is present directly inside your main application.
<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Label id="myLabel" text=""/> // So inorder to set the label(myLabel) present here you will use directly the 2nd line of code.
<mx:CustomComp id="myCustomComp" /> // So inorder to set the label(myLabel) present inside this component you use 1st line of code.
</mx:Application>
Hope now its clear.
If this post answers your question or helps, please kindly mark it as such.
Thanks,

How do i use objects from one class in anohter?
Hey
I have two GUI classes ShowWhiteGUI and BasketGUI and then a control class ShowWhite. The control class calls all the method from anohter class's which the GUI classes are gonna use.
The basis idea with this script is it shall be a very very simpel Shop. Where you can add items to a basket and then show the items in a new window(BasketGUI).
So here is the problem. I cant create an object in both GUI classes, because then im working with two sets of data, right? So how do i do this?
Here is my code:

Access oracle database from different classes in desktop / standalone app.
I am a bit confused as to what way to go. I am building a desktop application that needs to access an oracle database. I have done this in the past using code similar to the following:
try { DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver()); Connection conn = DriverManager.getConnection( "jdbc:oracle:thin:@111.111.111.111:oracledb", "username", "password" ); // Create a Statement Statement stmt = conn.createStatement(); ResultSet rs = stmt.executeQuery( "select ... from ..."); while (rs.next()) { ReportNumberCombo.addItem(rs.getString(1)); } // end of rs while conn.close(); } // end of try catch( Exception e ) { e.printStackTrace(); }
The problem I would like to resolve is that I have this code all over the place in my application. I would like to have it in one objects method that i can call from other classes. I can't easily see how to do this, or maybe at this point I'm just too confused.
I want to be able to change this connection info from a properties file which I have already done, not sure if this bit of information would change the answer to my question. I was also looking at the DataSource api, this looks like it is close to what I should use, what are your thoughts?
I would also like to if JNDI is only for web applications or would be appropriate for a desktop app.
Thank you for your help, I realize this is all over the place but I really need these topics cleared up!I have tried exactly that and am getting an error which let me to believe it couldn't be done that way. Here is my code and error message:
public class readPropsFile {
String getURL() throws IOException {
// default values for properties file
String Family = "Family:jdbc" + ":oracle:" + "thin:@";
String Server = "Server:111.111.111.111";
String Port = "Port:1521";
String Host = "Host:oradb";
String Username = "Username:username";
String Password = "Password:password";
try {
new BufferedReader(new FileReader("C:\\data\\Properties.txt"));
} catch (FileNotFoundException filenotfound) {
System.out.println("Error: " + filenotfound.getMessage());
// displays to console if file DOES NOT exist
System.out.println("The file DOES NOT exist, now creating...");
FileWriter fileObject = null;
fileObject = new FileWriter("c:\\data\\Properties.txt");
BufferedWriter out = new BufferedWriter(fileObject);
// writes to output as simple text.
out.write(Family);
out.newLine();
out.write(Server);
out.newLine();
out.write(Port);
out.newLine();
out.write(Host);
out.newLine();
out.write(Username);
out.newLine();
out.write(Password);
out.newLine();
out.close();
// displays to console if file exists
System.out.println("The file exists, or was created sucessfully");
// creates the properties object, assigns text file.
Properties props = new Properties();
FileInputStream in = new FileInputStream("c:\\data\\Properties.txt");
props.load(in);
Family = props.getProperty("Family");
Server = props.getProperty("Server");
Port = props.getProperty("Port");
Host = props.getProperty("Host");
Username = props.getProperty("Username");
Password = props.getProperty("Password");
// prints properties to a file for troubleshooting
PrintStream s = new PrintStream("c:\\data\\list.txt");
props.list(s);
in.close();
String URL = "\"" + Family + Server + ":" + Port + ":" + Host + "\"" +
"," + "\"" + Username + "\"" + "," + "\"" + Password + "\"";
System.out.println("This is the URL:" + URL);
return URL;
}And here is where I try to call the method:
public class connWithProps1 {
public static void main(String[] args) {
readPropsFile callProps = new readPropsFile();
try {
callProps.getURL();
String url = callProps.getURL(); // not needed
System.out.println("The URL (in connWithProps1) is: " + csoProps.getURL());
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection(url);
// Create a Statement
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select .... WHERE ....'");
while (rs.next()) {
System.out.println(rs.getString(1));
} // end of rs while
conn.close();
} catch (SQLException sqle) {
Logger.getLogger(connWithProps1.class.getName()).log(Level.SEVERE, null, sqle);
} catch (IOException ioe) {
Logger.getLogger(connWithProps1.class.getName()).log(Level.SEVERE, null, ioe);
}The error I get is:
SEVERE: null
java.sql.SQLException: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
The Connection descriptor used by the client was:
111.111.111.111:1521:oradb","username","password"

at oracle.jdbc.driver.T4CDriverExtension.getConnection(T4CDriverExtension.java:33)
at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:474)
{code}
Although the URL prints out correctly and when I tried plugging in the URL manually, it works just fine. One other thing I noticed was the line "The file exists, or was created sucessfully" is output 3 times.
I will go back and change my code to properly close the resultset, thanks for catching that. Id rather use what I have instead of JNDI unless it's nesessary.

How to access Excel files from different locations?
Hello,
I have successfully tested the Excel sample on WLS 7, and trying to run it on
the WLS 8.1.
Anyways, the common question for both is, how to access an excel files from different
locations (e.g. c:\path\1.xls, \\domain1\finance\fin.xls, \\domain1\marketing\customer.xls,
\\domain2\accounts\vouchers.xls)?
From example i can see that it picks from a specific path under repository.
Thanks
Ashok GuptaThe custom function sets the MS-Excel default directory to System.getProperty("user.dir")+"/excel"
(the domain directory), then opens the filename passed as a parameter. I assume
that if you pass in the fully specified path for the excel file ( like d:\MyDir\data\test.xls),
that it would open that file.

How to access Captivate Objects From Widget
Using the widget factory, is there a way to access a specific property such as a button or textbox in a captivate movie from an widget?
The button in captviate does have an instance name called button_mc. In my widget, I do have
myRoot = MovieClip(root);
mainMov = MovieClip(myRoot.parent.root);
Also, how can you get the slide properties such as total frames?
Can't seem to find out how or I am just missing something
ThanksHi Ukie,
Here's an article on how to access objects on the Captivate slide with WidgetFactory: http://www.infosemantics.com.au/widgetking/2010/10/slip-sliding-away/
In short, pass in the instance name of the button into the getSlideObjectByName() method:
var myButton:Sprite = getSlideObjectByName("button_mc");
Also, WidgetFactory has a property widgetSlide wich gives you access to the slide that the Captivate Author placed the widget on. This is a MovieClip, so if you wanted to read its total frames, you'd write:
widgetSlide.totalFrames;
Hope that answers your questions. -

How to make versionable object of different class than Document?
In the programmers reference is that every PublicObject can be versioned, but there are only samples for versioning documents. I would like to keep history on folder hierarchy changes, so I think I need a Folder that can be versioned.
The question is how to do this?
Should I override isVersionable method in subclass of Folder to return true?

Very Urgent:How to view an object from different angles around 360degrees
Hello
My problem is that i want to view an object which is drawn on the canvas3d in the simpleuniverse from all angles...i mean around 360degrees.
Suppose i have a front view... and i wan to look at the view..at 30 degree ..
plz help me
this is urgent
regards
seemaThanks Titus76. Your technique works. But one more problem. I want to rotate my all the three axis through some specified angle. In other words I want to rotate my viewport. In previous case if I implement ur suggestion only my object rotates, but not axis'. Now I want to rotate my all 3 axis. So that when I rotate, all my three axis rotate. This way my objects should obviously rotate. How will I do that?

How to access same ejb from different applications
Hi
I have two applications (.ear). Each application has 4 EJBs. These EJBs are same in both applications including their names. JNDI names are also same in each application.
in detail
ApplicationA (appA.ear) contains
web1.war
ejb1.jar
ejb2.jar
ejb3.jar
ejb4.jar
and
ApplicationB (appB.ear) contains
web2.war
ejb1.jar
ejb2.jar
ejb3.jar
ejb4.jar
both web1.war and web2.war has same JNDI references to these EJBs.
The problem:
If you access the applicationA, works fine. But if you access applicationB, it throws ClassCast Exception
After restarting.....
If you access the applicationB, works fine. But if you access applicationA, it throws ClassCast Exception
Both the applications are not working same time.
I suspect that It is because both applications have same ejbs and with same JNDI names.
Please validate.
Thanks

How to access workflow variables from business classes?
In WLI2.1 the com.bea.wlpi.server.admin.Admin bean was useful to retrieve workflow
variables for a particular instance id.
Is there anything similar in 8.1?
We have to do the following:
In the workflow, when a particular task gets created, a user (claimant of the
task) should be able to pull the workflow xml data in a JSP. The user may update
the data from the JSP and then the updated xml needs to be saved in the workflow.
Then, onTaskCompleted, the updated xml will follow the rest of the workflow.
How to do this is 8.1?
Thanks in advance.Hi,
Pls check for setRequest/setResponse in task control and setTasksRequest/setTasksResponse
i task worker control. Hope this will resolve your issues as they have XmlObject
as parameter.
Regards
