Getting attribute properties from client tier is too slow

Getting properties for view object attributes is too slow, because a called to the server is made for every attribute.
I noticed that when a property is gotten for an attribute all properties are retrieved for it, but I couldn't found a way to get all properties for all attributes in the ViewObject.

See ApplicationModule.fetchAttributeProperties and it's usage in JClient in JDeveloper 9.0.3

How to get attribute value from standard page ?

Hi,
How to get attribute value from standard page ?
String str = (String)vo.getCurrentRow().getAttrbute("RunId");
But this value is returning a null value ....
Can anyone help me to get this attribute value which is actually having a actual value .

getCurrentRow() would always return null if no setCurrentRow() is used.
Please check the page design and understand how many rows of VO are there. You can also use the following to get the row:
vo.reset();
vo.next();

Getting database properties from current container

Hi guys
I'm a trainee java developer and I'm struggling... I've done countless google's & I'm not getting anywhere...
I won't mind if the response to this post is RTFM, but at least could you point me in the right direction :)
My manager told me to replace all our ejb finders to rather use Hibernate (www.hibernate.org).
I got that working very cool, but the way I setup Hibernate's SessionFactory is through an xml file:
Example:
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE hibernate-configuration (View Source for full doctype...)>
- <hibernate-configuration>
- 
- <session-factory name="java:comp/env/hibernate/SessionFactory">
- 
<property name="connection.driver_class">org.hsqldb.jdbcDriver</property>
<property name="connection.url">jdbc:hsqldb:hsql://localhost:1703</property>
<property name="connection.username">sa</property>
<property name="connection.password" />
<property name="dialect">net.sf.hibernate.dialect.HSQLDialect</property>
- 
<mapping resource="za/co/strate/safe/reports/CountPartyUnmatchedOrdersVO.hbm.xml" />
</session-factory>
</hibernate-configuration>
Now my manager want's me to rather get these database connection properties from the current ejb container (not hard-coded in any file)...
We have client's running JBoss & IBM WebSphere...
Any pointers would be greatly appreciated!
Thanks!
Anthony

Now my manager want's me to rather get these database connection properties from the current ejb container (not hard-coded in any file)...
Tell you'r manager that he is a stupid asshole who has no clue about what he is talking.
Because what he wants is not possible

How to get attribute value from an object inside an object in Xpress

Does anyone know how to get an attribute value from an object in Xpress in a workflow? I have an object structured as follows:
<ResourceInfo accountId='mj628' tempId='3483372b787ce7dd:-5d99a0c5:130cb238483:-3600'>
<ObjectRef type='Resource' name='Google Apps'/>
</ResourceInfo>
I need if possible to get the name='Google Apps', which is inside the ObjectRef, so I guess its an attribute value of an object inside an object.

If the ResourceInfo object is accessible in a variable, i.e. named "myResInfo", you just have to check the Java API and call the relevant method:
<invoke name='getResourceName'>
<ref>myResInfo</ref>
</invoke>

Get attribute name from VO returns null.

Hello,
I'm using JDeveloper 11.1.1.3. I have an af:inputfile component in which i set a ValueChangeListener. I'm using the attribute "Filename" from the form view to set the name of the file before saving it to a directory. At first, i had a different layout for my jspx page (very similar in design) and everything was working perfectly. When i redesigned the page, i'm now getting "null" as the filename. I'm not able to get the attribute! Although i didn't change anything in the code! I tried writing a simple method to output the attribute:
      public String justOutput(){
        BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
        AttributeBinding attr = (AttributeBinding) bindings.getControlBinding("Filename");
        if (attr == null)
            return null;
        String filename = (String) attr.getInputValue();
        System.out.print(filename);
        return null;
      }It was able to output the attribute. But in my original method i'm getting "null".
******Another important observation*******
If i pressed upload another time at runtime and uploaded another file it works again!
Here is my code:
     public void uploadFile(ValueChangeEvent valueChangeEvent) {
          InputStream in;
          FileOutputStream out;
          ExternalContext context = FacesContext.getCurrentInstance().getExternalContext();
          String fileLoc = context.getInitParameter("DATA_DIR");
          UploadedFile file= (UploadedFile)valueChangeEvent.getNewValue();
          boolean exists = (new File(fileLoc)).exists();
          if(!exists){
            (new File(fileLoc)).mkdirs();
          if(file != null && file.getLength() > 0){
            FacesContext context2 = FacesContext.getCurrentInstance();
            FacesMessage message = new FacesMessage("File Uploaded" + file.getFilename() +
                                                    "(" + file.getLength() + "bytes)");
            //context2.addMessage(valueChangeEvent.getComponent().getClientId(context2), message);
            BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
            AttributeBinding attr = (AttributeBinding) bindings.getControlBinding("Filename");
            if (attr == null)
                return;
            String filename = (String) attr.getInputValue();
            try {
                     out = new FileOutputStream("C:\\demos\\" + filename + ".pdf");
                     in = file.getInputStream();
                     for (int bytes=0; bytes < file.getLength(); bytes++) {
                         out.write(in.read());
                     in.close();
                     out.close();
                 } catch (IOException e) {
                 e.printStackTrace();
          else {
              String filename = file != null ? file.getFilename():null;
              String byteLength = file != null ? "" + file.getLength():"0";
      }I don't think the code is wrong because it worked before. But why is this happening?
Can anyone please help!?
Mohamed.

Sorry for the late reply Frank,
Thanks for your reply, no i didn't! But it worked when i set the 'autosubmit' property to true... Like you said:
the name field hasn't updated the model to the time you try and access itThanks again.

How to get promoted properties from Request to Response in two way send port scenario.

I have a requirement to access the promotes properties in response pipeline, these promoted properties are promoted in Orchestration and they are available in Send pipeline, but not available in Receive pipeline. Please help us if we have any solution for
this issue.
Thanks
Ramachandra

Hi Ramachandra,
Obviously from above responses you would have got the point that this can’t be done out-of-box and you need to do custom. Also when you say “Get the message
from DB along with context properties.”, you do agree with this point.
One of the possible custom solutions is (Obviously in bespoken process, you can achieve it in many ways),
When send the message out to a solicit-response port, store those promoted properties in db along with the “correlation key” which you can get from the context of the request message like
“Correlation Token” and “SPID”. So when the response comes back, you can either in the “inbound map” or in the receive pipeline (using custom component) populate/constructs the message by populating data from db, where will retrieve the
“Correlation Token” and “SPID” values of the response message (it will have the same correlation value as in the request message), so you can use the value of correlation sets to get the values from db.

M.R.Ashwin Prabhu

How to get attribute values from one view to another

HI all,
Thx in Advance..
I have 2 view like v1,v2.In v1 i used one attribute values from "get single attribute" method.And i need the same values in v2 screen.For this i did in v1 outbound plugs , i mentioned the parameter name . How can i get the same values in v2.

Hi chandru ,
you said you declare the parameters in the Outbound Plug of V1. now go to view V2 inbound plug Tab and creat one inbound plug
double click on the plug name .it will navigate you to the event handeler method . Now add the outbound parameter variables in the
parameters
For example : V1firing the navigation plug
a type string " defined in parameter
wd_this->fire_out_to_view2_plg(
    a =      'ABCD'                           " string
you can retrive the value freely in v2 inbound event handeler
a type string " defined in parameter
*   set single attribute
    lo_el_context->set_attribute(
      name = `TEXT`
      value = a )." here you will get the 'ABCD'.

How to get MAC address from client machine ?

Hi dear,
We are implementing security measures for a banking system, so it is required that we track the MAC address of the registered clients along with other parameters. How do we get the MAC address from client machine using ADF or running scripts in client side?
thanks all

Hi,
Welcome to OTN.
Your question has nothing to do with ADF as such. Googling would give you plenty of such topics.

HT4718 Can't download "aditional components" from recovery. Internet too slow. What do I do now?

Hello,
I am overseas for a month and I had to erase my hard drive and do a fresh install of OSX Lion.
I erased my drive and all went fine. Now I am trying to reinstall the OS from the COMMAND+R menu. The problem is my internet connection here is too slow for the "aditional components" and it ends of hanging on 9 hours or something and then just says it failed to download the aditional components. I now it isn't a hardware issue because I have done this before while I was in the states with a fast conection and it worked both times I have reinstalled the OS.
I was wondering how large is the "aditional components"?
What is the point of the Recovery HD if I need to download the recovery from the internet anyway?
Who was the genius that made the decision to eliminate the install CDS? Espceically when were overpaying for these machines. And what made this genius assume that every one has access to fast internet speeds?
Thank you,

And what made this genius assume that every one has access to fast internet speeds?
Requirements for reinstalling OS X Lion or OS X Mountain Lion
Reinstalling OS X Lion or OS X Mountain Lion via OS X Recovery requires broadband access to the Internet via Wi-Fi or an Ethernet connection. OS X is downloaded over the Internet from Apple when OS X Recovery is used for reinstallation.

Getting IP address from client

Our application suite is a mish-mash of client-server, web-applications and web pages. One of the requests by our client is to allow them to login into one application and then go directly to another without having to enter their password again. One method we thought of is to capture the IP address of the client when they login, or posssibly send it with the login request. Is there an easy reliable way to do this? The other method I thought of is after logging in the client would be given a key. Where could I store this key? I was thinking in the registry but I am trying to avoid Windows specific design.
On a side note I am looking at JAAS. It seems that JAAS just gives us a standard access interface, does it the features I am looking for by any chance?

Use an application bean if you want to keep a list of
all the users stored on a server.
When someone logs on, grab the ip, login name, and
password. Store this in the application scope bean.
Every time a page is accessed, check the ip to see if
it has been previously stored in the bean. If so,
load the login and password and use them for logging
in to the page. If not, include another preset login
page, or lik to it with the previous page stored in a
session scope bean.
The ips, login names, and passwords should be enclosed
in a class (simple one with three fields). When
someone logs on, create a new instance and send it to
the application scope bean, where it should be stored
in a java.util.HashMap (my favorite kind, and really
quick).
There should also be a way to time-out the user after
a while of not connecting - removing their ip from the
application scope bean. Very important if you want
security.
That's all I can think of for now.
Spaceman40Close enough, however I will point out that you don't need to store the password. I am also confused why you are saying an application level bean. This needs to be a bean that can be accessed by all of our applications. If one application creates the bean all of them should be able to see it.
I was thinking of doing this: Each application gets a session bean that looks for an entity bean with the primary key of the client's IP address. If the bean is there it gets the user ID from that and logs that user into the system. If the bean isn't there, it fires off a login procedure for the client to enter their username and password. If the login is successful it creates the bean. The session bean stays around until the user logs out of the system. The last session bean linked to that entity bean destroys it.
Has anyone seen this before? Is there a design pattern for a last one out turn off the light in EJB?

Get Attribute values from a page and procedure exception handling?

Hi All,
I have created new page with two input attributes not based on any VO. This page is created to capture two values and pass these to an AM method upon pressing OK button. The method in AM will call a procedure with two in parameter expecting the two values captured from the above said page.
I have two questions, first one how to capture the values entered by the page in the controller class and advises me how to handle exceptions when my procedure fails.
I can not use something like this since this page is not based on a VO
String fromName = (String)vo.getCurrentRow().getAttribute("FromName");
Do I have to create a dummy VO like select '' name1, '' name2 from dual?
Thanks for the help.

Hi,
Actually you can capture the parameters on the page like this way
String test = (String)pageContext.getParameter("id of the text input bean");
Now in procedure you can take an out parameter which stores the error messages on exception
and return that out parameter in java.
and then you can throw exception on page using OAException class.
Thanks

How to get mouse properties from Graphs/Charts?

Hello,
My problem is the following:
I have a graph that displays some data and two cursors.
Next to it is a button that allows users to select whether
they want to see all data, or a selection based on the
cursors. When in the selection mode, the cursor can be
dragged to change the data shown, but the graph is updated
while dragging. I wanted to make a simple wait-while-mouse-down
call, but this seems to be more complex than I imagined.
I know the example that uses the picture frame to get the mouse
properties, but the picture frame blocks cursor usage. Is there
another solution to my problem?

Hello,
The best way to achief this is using an event structure to capture a mouse button up. I have changed your program in a way that it uses an event structure to look at the waveformgraph. As soon as a mousebutton up occurs, it stops the while loop where it is waiting in and updates the graph according to the new currsor settings.

Getting Model Identifier # from clients

Where can I find the model identifier number (like iMac8,1 MacPro3,1, etc) on ARD client computers?

Hi
I've looked at the interface and I don't think this is available as an option? One of the other guys may know of a way? You could do this easily using this command:
system_profiler SPHardwareDataType | grep "Model Identifier" | awk '{ print $3; }

Streaming HD video from iMac to ATV2 too slow, but from iPhone4 works fine

When streaming HD (720p) video from iTunes on my iMac (2006 2Ghz Intel Core Duo) to my ATV2 it is painfully slow. So slow as to be unusable (watch 2 minutes, wait 5 minutes of buffering, watch 2 minutes...and so on). However, if I stream the exact same HD video from my iPhone 4 via AirPlay to the ATV2 it works perfectly. There's hardly even any initial buffering delay. The iMac, ATV2 and iPhone 4 are all on the same 802.11g WiFi network. What the **** could be causing such a difference in data transmission speeds between iMac and iPhone 4??
Is the AirPort in my iMac so much worse than the WiFi in my iPhone4?

TheOneAndOnly BiGMaC wrote:
The file is decreased in size from the size you have in your library in order to load on the iPhone and play there.
No, in this case the file is exactly the same size (1.95Gb). The iPhone 4 can handle 720p HD video.
A g network is plenty fast enough to stream 720p HD, which requires 4-5Mbps, a tenth of what a g network is technically capable of. In any case, the fact that I could stream the exact same file from my iPhone to the ATV2 via wireless shows the network itself is not the problem.
After doing some tests, it would appear that the wireless performance of the AirPort on my iMac is the culprit. My ISP connection is a 50Mbps fibre link, and in network speed tests my iPhone (sitting right next to my iMac) can get 8Mpbs whereas the iMac struggles to get 1Mpbs. Running ethernet to my iMac is not practical and in any case, the g network should be plenty fast enough for what I need. I need to try and figure out what's holding my iMac's AirPort back.
