ADF 10.1.3 : Saving VO results when application is closed.

Hello,
I have written to code to save the VO results in a file which i want to call when application is closed. So in which method should i call the code so that VO results are always saved irrespective of how application window is closed.
Also i want to load the VO results into the VO when application starts, in which method should i do this?
Regards
Lokesh

John,
Thanx for the reply. Let me elaborate my requirement.
My application is a web application. I have created a VO [not based on sql query]. This VO is populated by the user by providing various inputs on the application page. All i want to do is store these VO rows on the user file system when the user closes the application and then reload these rows back into the VO from the stored file when user reopens the application.
Now i don't want to keep writing the rows on file system as soon as VO is populated as this would lead to bad performance, so i am looking to save the VO rows when application closes. Is there any way to do it??
Regards
Lokesh

Problem when application is closed using CTRL-C

When my app is launched it displays a JFrame and connects to a DB. In my GUI I have a windowClosing event handler and also a handler for a Disconnect button which will gracefully close the DB connection befor exiting.
However when a user executes from the Cmd prompt a CTRL-C command to kill the application ( for what ever reason ) the application has no way of closing any open DB connections. How can I get around this problem?

Hi,
Add a shutdown hook:

It will execute when the jvm is about to terminate.

20.0.1: File== New Window & New Private Window will not open then Firefox will not stop running when application is closed

Although nothing appears to be happening when clicking on either New Window or New Private Window there seems to be processes started because when I try to close Firefox and reopen, I get an error message saying that Firefox is already running. My only option then is to stop the processes via Task Manager. I have tried (several times) to uninstall and reinstall.

Although advised not to, I finally hit the reset button in the Save Mode Window. This corrected the problem. I suspect a faulty add-on - I try and reject many. I will add them back on at a time as I develop the need. Thanks for you help.

Javaw.exe is still running when application is closed

The application works fine. when i close the application using "x" at the top of the window the javaw.exe is still running in task manager. javaw.exe is accumulating all memory when i run the again. The same problem occurs when i run the application through jar. Any help is appreciated

If you use
jframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
and you close de window, all your applications
running in the JVM will be closed too because System
exit is used. I prefer to use
jframe.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOS
E);
Alejandro H.If you had read the OP, he was complaining that the JVM was still running even though he had closed his application, which meant he wanted to stop the JVM.

I am using Lightroom 5 and am hapy about it, but recently I hav encountered a problem when trying to edit an image in another program, i.e. Elements. I used the clone tool, saved the result and went back to Lightroom to open the image there. I did find a second copy, but this is identic with the one I already had in Lightroom, and I can see noe result of the clone process.

At the moment I would say it is uncertain whether Acrobat is completely ignoring the change, or whether the changes you are making aren't affecting the ink density. I have a suggestion for a test you could make to see which is the case.
When editing in Photoshop just add a box or mark on the image, for your tests.
- If this box does not appear in Acrobat, you know Acrobat is not seeing the edit
- If this box does appear in Acrobat, you know the problem is that your tool for changing ink densities is not taking effect.

Saving query result to a file

Hi,
I have a sql*developer version 1.5 but i am getting a problem while saving query result to a file. When i click on "script output "-> "file icon" nothing is showing.
Can anyboby guide me whether its a bug or some other settings are required.
I have oracle 10.2.0.3 working on linux.
Thanks & regards
Girish

I am getting the same thing and as far as I know it is a bug.
As a workaround, you can either copy the contents of the script output or run the query as a statement (F9) instead of as a script (F5) and export the query results from the results tab.

ADF how to display a processing page when executing large queries

ADF how to display a processing page when executing large queries
The ADF application that I have written currently has the following structure:
DataPage (search.jsp) that contains a form that the user enters their search criteria --> forward action (doSearch) --> DataAction (validate) that validates the inputted values --> forward action (success) --> DataAction (performSearch) that has a refresh method dragged on it, and an action that manually sets the itterator for the collection to -1 --> forward action (success) --> DataPage (results.jsp) that displays the results of the then (hopefully) populated collection.
I am not using a database, I am using a java collection to hold the data and the refresh method executes a query against an Autonomy Server that retrieves results in XML format.
The problem that I am experiencing is that sometimes a user may submit a query that is very large and this creates problems because the browser times out whilst waiting for results to be displayed, and as a result a JBO-29000 null pointer error is displayed.
I have previously got round this using Java Servlets where by when a processing servlet is called, it automatically redirects the browser to a processing page with an animation on it so that the user knows something is being processed. The processing page then recalls the servlet every 3seconds to see if the processing has been completed and if it has the forward to the appropriate results page.
Unfortunately I can not stop users entering large queries as the system requires users to be able to search in excess of 5 million documents on a regular basis.
I'd appreciate any help/suggestions that you may have regarding this matter as soon as possible so I can make the necessary amendments to the application prior to its pilot in a few weeks time.

Hi Steve,
After a few attempts - yes I have a hit a few snags.
I'll send you a copy of the example application that I am working on but this is what I have done so far.
I've taken a standard application that populates a simple java collection (not database driven) with the following structure:
DataPage --> DataAction (refresh Collection) -->DataPage
I have then added this code to the (refreshCollectionAction) DataAction
protected void invokeCustomMethod(DataActionContext ctx)
super.invokeCustomMethod(ctx);
HttpSession session = ctx.getHttpServletRequest().getSession();
Thread nominalSearch = (Thread)session.getAttribute("nominalSearch") ;
if (nominalSearch == null)
synchronized(this)
//create new instance of the thread
nominalSearch = new ns(ctx);
} //end of sychronized wrapper
session.setAttribute("nominalSearch", nominalSearch);
session.setAttribute("action", "nominalSearch");
nominalSearch.start();
System.err.println("started thread calling loading page");
ctx.setActionForward("loading.jsp");
else
if (nominalSearch.isAlive())
System.err.println("trying to call loading page");
ctx.setActionForward("loading.jsp");
else
System.err.println("trying to call results page");
ctx.setActionForward("success");
Created another class called ns.java:
package view;
import oracle.adf.controller.struts.actions.DataActionContext;
import oracle.adf.model.binding.DCIteratorBinding;
import oracle.adf.model.generic.DCRowSetIteratorImpl;
public class ns extends Thread
private DataActionContext ctx;
public ns(DataActionContext ctx)
this.ctx = ctx;
public void run()
System.err.println("START");
DCIteratorBinding b = ctx.getBindingContainer().findIteratorBinding("currentNominalCollectionIterator");
((DCRowSetIteratorImpl)b.getRowSetIterator()).rebuildIteratorUpto(-1);
//b.executeQuery();
System.err.println("END");
and added a loading.jsp page that calls a new dataAction called processing every second. The processing dataAction has the following code within it:
package view;
import javax.servlet.http.HttpSession;
import oracle.adf.controller.struts.actions.DataForwardAction;
import oracle.adf.controller.struts.actions.DataActionContext;
public class ProcessingAction extends DataForwardAction
protected void invokeCustomMethod(DataActionContext actionContext)
// TODO: Override this oracle.adf.controller.struts.actions.DataAction method
super.invokeCustomMethod(actionContext);
HttpSession session = actionContext.getHttpServletRequest().getSession();
String action = (String)session.getAttribute("action");
if (action.equalsIgnoreCase("nominalSearch"))
actionContext.setActionForward("refreshCollection.do");
I'd appreciate any help or guidance that you may have on this as I really need to implement a generic loading page that can be called by a number of actions within my application as soon as possible.
Thanks in advance for your help
David.

Outlook.mailitem - diferent replace result when not displayed

Hello everybody!
I am developing an app to generate personalized emails from Excel file and .msg template.
In the template, I insert "variables" like this: ^name^,
which means that is is a placeholder for values from "name" column in source
Excel file.
this template is saved as .msg file on local disc and used as an argument in.CreateItemFromTemplate()
after loading the template , it cycles from all the columns and rows of the Excel file and replaces the inserted
variables:
loading excel:
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim fpath As String
OpenFileDialog1.ShowDialog()
fpath = OpenFileDialog1.FileName
workbook = APP.Workbooks.Open(fpath)
worksheet = APP.ActiveSheet
Dim CellData As String
Dim LastCol As Long
Dim LastRow As Long
Dim bunka As String
LastCol = workbook.ActiveSheet.UsedRange.Columns.Count
LastRow = workbook.ActiveSheet.UsedRange.Rows.Count
objData = worksheet
DataGridView1.ColumnCount = 1
DataGridView1.Columns(0).Name = "Column"
DataGridView1.Columns(0).Width = 130
For i = 1 To LastCol
bunka = worksheet.Cells(1, i).Value
Combo_To.Items.Add(bunka)
Combo_SaveName.Items.Add(bunka)
Dim row As String() = New String() {bunka}
DataGridView1.Rows.Add(row)
Next
Dim btn As New DataGridViewButtonColumn()
DataGridView1.Columns.Add(btn)
btn.HeaderText = "Use"
btn.Text = "+"
btn.Name = "btn"
btn.Width = 50
btn.UseColumnTextForButtonValue = True
btn.CellTemplate.Style.BackColor = System.Drawing.Color.Green
Combo_To.SelectedIndex = 1
End Sub
after that the DataGridView1 loosk like this:
the "+" buttons are used to insert text variables into the mail body.
code for inserting is, this works fine:
Private Sub grdData_CellContentClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
Dim colName As String = DataGridView1.Columns(e.ColumnIndex).Name
If e.RowIndex < 0 Then Exit Sub
If colName = "btn" Then
Dim variable As String
variable = "^" & DataGridView1.Item(0, e.RowIndex).Value & "^"
My.Computer.Clipboard.SetText(variable)
objOutlookMsgY.GetInspector().Activate()
SendKeys.Send("^v") 'Paste
End If
End Sub
code for generating email from template:
Private Sub Button4_Click(sender As Object, e As EventArgs) Handles Button4.Click
Dim sessionName As String
Dim docas As Object
Dim variable As String
Dim dosazeno As String
Dim SavePath As String
Dim objOutlookMsgTEMP As Outlook.MailItem
worksheet = APP.ActiveSheet
objOutlookMsgY.SaveAs("C:\temp_msg2.msg")
clip = objOutlookMsgY.HTMLBody
MsgBox("clip saved")
sessionName = InputBox("Name this session:", "New Session", Today & "_")
SavePath = RootFolder & "\" & sessionName & "\_Initial session"
My.Computer.FileSystem.CreateDirectory(SavePath)
For radek = 2 To workbook.ActiveSheet.UsedRange.Rows.Count
ToolStripProgressBar1.Maximum = workbook.ActiveSheet.UsedRange.Rows.Count - 1
objOutlookMsgTEMP = objOutlook.CreateItemFromTemplate("C:\temp_msg2.msg")
' objOutlookMsgTEMP.Display()
For i = 1 To DataGridView1.RowCount
variable = Convert.ToString("^" & worksheet.Cells(1, i).value & "^")
dosazeno = Convert.ToString(worksheet.Cells(radek, i).value)
'wait(50)
Debug.Print("*" & variable & "*" & " >>> " & "*" & dosazeno & "*")
objOutlookMsgTEMP.HTMLBody = objOutlookMsgTEMP.HTMLBody.Replace(variable, dosazeno)
objOutlookMsgTEMP.HTMLBody = Replace(objOutlookMsgTEMP.HTMLBody, variable, dosazeno)
'wait(50)
objOutlookMsgTEMP.To = worksheet.Cells(radek, ToCol + 1).value
Next
objOutlookMsgTEMP.SendUsingAccount = accounts(Combo_From.SelectedIndex + 1)
Dim objDoc As Microsoft.Office.Interop.Word.Document
Dim objBkm As Microsoft.Office.Interop.Word.Bookmark
'On Error Resume Next
objDoc = objOutlookMsgTEMP.GetInspector.WordEditor
objBkm = objDoc.Bookmarks("_MailAutoSig")
If Not objBkm Is Nothing Then
objBkm.Select()
objDoc.Windows(1).Selection.Delete()
End If
objDoc = Nothing
objBkm = Nothing
objOutlookMsgTEMP.SaveAs(SavePath & "\" & worksheet.Cells(radek, Combo_SaveName.SelectedIndex + 1).value & ".msg")
' objOutlookMsgTEMP.Send()
ToolStripProgressBar1.Value = radek - 1
objOutlookMsgTEMP.Close(SaveMode:=Outlook.OlInspectorClose.olDiscard)
Next
End Sub
for replacing is used this:
.....objOutlookMsgTEMP.Display()
objOutlookMsgTEMP.HTMLBody = objOutlookMsgTEMP.HTMLBody.Replace(variable, valueFromExcel).....
or
.....objOutlookMsgTEMP.HTMLBody = Replace(objOutlookMsgTEMP.HTMLBody, variable, valueFromExcel).....
after replacing, the new message is saved as .msg or send
the problem:
everything works fine when the message is displayed while replacing. But when not displayed, only SOME variables
are replaced. I don't really understand why there is such difference in the result and why only SOME are
not replaced. I have tried changing the columns's names but found no connection between it and the result. when the message is displayed it takes like 10 times longer and makes the PC unusable.
real example:
the tamplate:
^jmeno^
^email^
^prij^
^jmeno3^
^sec code^
result, message displayed:
Jakub
[email protected]
Dxxx
16
266548
result, message not displayed:
^jmeno^
[email protected]
^prij^
4
449447
I have also tried adding some Wait functions, didn't help. I would really appreciate if you could help me
figure this out and explain why this happens. Thank you

Please also copy the below two vars from the debugger window and paste here as it is.
Debug.Print("*" & variable & "*" & " >>> " & "*" & dosazeno & "*")
Also send us you message template, you can send only the section where the two non working vars exist.

ADF server-side state saving method

Hi all,
As far as I know, ADF has three view state saving methods.
1. client - tokens
2. client - all
3. server
My question is about server-side state saving.
If I set state saving methos "server" in web.xml, view state is stored in session scope as LRU map.
And the size of the map can be configured with below parameters in web.xml.
<context-param>
<param-name>com.sun.faces.numberOfViewsInSession</param-name>
<param-value>10</param-value>
</context-param>
<context-param>
<param-name>com.sun.faces.numberOfLogicalViews</param-name>
<param-value>5</param-value>
</context-param>
However I think these parameters is offered by Mojarra (Sun's JSF RI) and any ADF guides don't mention them.
These parameters are supported in ADF?
Regards,
Atsushi

Hi,
don't have a support statement for this but would be surprised if we don't as ADF Faces runs on top of the JSF RI.
However, I am wondering why your customer prefers state saving being handled on the server as it doesn't allow fail over for your application setup. Also it is the recommended option
http://docs.oracle.com/cd/E25054_01/web.1111/b31973/ap_config.htm#CEGECDJF
+"Context parameter javax.faces.STATE_SAVING_METHOD: Specifies where to store the application's view state. By default this value is server, which stores the application's view state on the server. *It is recommended that you set javax.faces.STATE_SAVING_METHOD to client* when you use ADF Faces, to store the view state on the browser client. When set to client, ADF Faces then automatically uses token-based, client-side state saving. *You can specify the number of tokens to use instead of using the default number of 15*.+
+You can specify the following state-saving context parameters:+
+org.apache.myfaces.trinidad.CLIENT_STATE_METHOD: Specifies the type of client-side state saving to use when client-side state saving is enabled by using javax.faces.STATE_SAVING_METHOD. The values for CLIENT_STATE_METHOD are:+
+token: (Default) Stores the page state in the session, but persists a token to the client. The simple token, which identifies a block of state stored back on the HttpSession object, is stored on the client. This enables ADF Faces to disambiguate the same page appearing multiple times. Failover is supported.+
+all: Stores all state information on the client in a (potentially large) hidden form field. It is useful for developers who do not want to use HttpSession.+
+*Performance Tip:*+
+Because of the potential size of storing all state information, it is recommended that you set client-state saving to token.+
+*org.apache.myfaces.trinidad.CLIENT_STATE_MAX_TOKENS*: Specifies how many tokens should be stored at any one time per user, when token-based client-side state saving is enabled. The default is 15. When the number of tokens is exceeded, the state is lost for the least recently viewed pages, which affects users who actively use the Back button or who have multiple windows opened at the same time. If you are building HTML applications that rely heavily on frames, you would want to increase this value.+
+*org.apache.myfaces.trinidad.COMPRESS_VIEW_STATE*: Specifies whether or not to globally compress state saving on the session. Each user session can have multiple pageState objects that heavily consume live memory and thereby impact performance. This overhead can become a much bigger issue in clustering when session replication occurs. The default is off.+
+org.apache.myfaces.trinidad.USE_APPLICATION_VIEW_CACHE: Enables the Application View Cache (AVC), which can improve scalability by caching the state for the initial renders of the page's UI at an application scope. However, every page in the application must by analyzed for support in the AVC to avoid potential problems with debugging in an unexpected state and information leakage between users. Additionally, development is more difficult since page updates are not noticed until the server is restarted, and although initial render performance is enhanced, session size is not.+
+*CAUTION:*+
+The Application View Cache is not supported for this release. The feature does not work for any page where the rendering of the component tree causes the structure of the component tree to change temporarily. Since this is often the case, USE_APPLICATION_VIEW_CACHE should not be used."+
So unless your customer has a good reason for server side state I would suggest him/her to go with best practices

I'm having trouble with something that redirects Google search results when I use Firefox on my PC. It's called the 'going on earth' virus. Do you have a fix that could rectify the vulnerability in your software?

I'm having trouble with a virus or something which affects Google search results when I use Firefox on my PC ...
When I search a topic gives me pages of links as normal, but when I click on a link, the page is hijacked to a site called 'www.goingonearth.com' ...
I've done a separate search and found that other users are affected, but there doesn't seem to be a clear-cut solution ... (Norton, McAfee and Kaspersky don't seem to be able to detect/fix it).
I'd like to continue using the Firefox/Google combination (nb: the hijack virus also affects IE but not Safari) - do you have a patch/fix that could rectify the vulnerability in your software?

Hi sunil,
Rod is referencing the NLS parameters i.e.
Can you please let me know which NLS parameters you are referring toNLS parameters in this scenerio may be the date and language for that session.Do check out
SELECT * from NLS_SESSION_PARAMETERS
how i can check if there any differences in the NLS parameters when report is scheduled or run interactivelyI think you should run the trace file.Iam not sure about it.
It would be system_context.
Hope it helps you.

Recently bought a new computer and all my music appears in iTunes as well as on my computer in a saved folder. When I try to play the music in iTunes I get an error that reads"the song could not be used because the original file could not be found."

Recently bought a new computer and all my music appears in iTunes as well as on my computer in a saved folder. When I try to play the music in iTunes I get an error that reads"the song could not be used because the original file could not be found. Would you like to locate it?" Hope you can help me solve this issue.
Thanks,
Shellyboo

This happens if the file is no longer where iTunes expects to find it. Possible causes are that you or some third party tool has moved, renamed or deleted the file, or that the drive it lives on has had a change of drive letter. It is also possible that iTunes has changed from expecting the files to be in the pre-iTunes 9 layout to post-iTunes 9 layout, or vice-versa, and so is looking in slightly the wrong place.
Select a track with an exclamation mark, use Ctrl-I to get info, then cancel when asked to try to locate the track. Look on the summary tab for the location that iTunes thinks the file should be. Now take a look around your hard drive(s). Hopefully you can locate the track in question. If a section of your library has simply been moved, or a drive letter has changed, it should be possible to reverse the actions.
Alternatively, as long as you can find a location holding the missing files, then you should be able to use my FindTracks script to reconnect them to iTunes .

To set an error while saving the order when the item categor changed in CRM

Hello SAP Gurus,
As per our current system set up, whenever the order created in CRM once replicated to ERP should not change the item category in CRM .If the item category is changed( allows the system) and saved, it gives an error as u201CItem category should not be changedu201D. We have been encountering this type of issue since long back
To avoid this type of issue, an error should through while saving the order when the user changes the item category in CRM.
Can someone help me to achieve this.
Thanks in advance.
Cheers

Sreedhar,
Can't you control it by Item Category determination?

WHERE    1 = 1
AND      ap.lenapp_account_number (+) = TO_NUMBER(SUBSTR(mhldr.account_number,1,8))
GROUP BY mhldr.account_number;      When run as a query, this code consistently returns 2 for the num_apps field (for a certain group of accounts), but when run as an INSERT INTO command, the num_apps field is logged as 1. I have secured the tables used within the query to ensure that nothing is changing the data in the underlying tables.
If I run the query as a cursor for loop with an insert into the applicant_summary table within the loop, I get the same results in the table as I get when I run as a stand alone query.
I would appreciate any suggestions for what could be causing this odd behaviour.
Cheers,
Steve

Yes, using COUNT(*) gives the same result as COUNT(1).
I have found another example of this kind of behaviour:
Running the following INSERT statements produce different values for the total_amount_invested and num_records fields. It appears that adding the additional aggregation (MAX(amount_invested)) is causing problems with the other aggregated values.
Again, I have ensured that the source data and destination tables are not being accessed / changed by any other processes or users. Is this potentially a bug in Oracle?Just as a side note, these are not INSERT statements but CTAS statements.
The only non-bug explanation for this behaviour would be a potential query rewrite happening only under particular circumstances (but not always) in the lower integrity modes "trusted" or "stale_tolerated". So if you're not aware of any corresponding materialized views, your QUERY_REWRITE_INTEGRITY parameter is set to the default of "enforced" and your explain plan doesn't show any "MAT_VIEW REWRITE ACCESS" lines, I would consider this as a bug.
Since you're running on 10.2.0.2 it's not unlikely that you hit one of the various "wrong result" bugs that exist(ed) in Oracle. I'm aware of a particular one I've hit in 10.2.0.2 when performing a parallel NESTED LOOP ANTI operation which returned wrong results, but only in parallel execution. Serial execution was showing the correct results.
If you're performing parallel ddl/dml/query operations, try to do the same in serial execution to check if it is related to the parallel feature.
You could also test if omitting the "APPEND" hint changes anything but still these are just workarounds for a buggy behaviour.
I suggest to consider installing the latest patch set 10.2.0.4 but this requires thorough testing because there were (more or less) subtle changes/bugs introduced with [10.2.0.3|http://oracle-randolf.blogspot.com/2008/02/nasty-bug-introduced-with-patch-set.html] and [10.2.0.4|http://oracle-randolf.blogspot.com/2008/04/overview-of-new-and-changed-features-in.html].
You could also open a SR with Oracle and clarify if there is already a one-off patch available for your 10.2.0.2 platform release. If not it's quite unlikely that you are going to get a backport for 10.2.0.2.

Form Builder crashes while saving .fmb file when connected to db

Hi,
I am getting error The instruction at "0x679c352c" referenced memory at "0x0000001c". The memory could not be "read".
Forms version is 6.0.8.11.3 and database version is 10.2.0.3.0
I am doing the following steps:
1) Open .fmb file in forms builder
2) Connecting to database
3) Making some changes in form
4) Compiling (Ctrl+Shift+K) and generating form (Ctrl+t)
5) Saving form <--- Here I am getting the error and form crashes
If I do not connect to database then builder is allowing me to save the file
1) Open .fmb file in forms builder
2) Making some changes in form
3) Saving form (Successful)
I did some exercise just as a guess that may some part of the form is causing this error. I full expanded all components of the form i.e. blocks, canvases, triggers etc.
This exercise produced that 3 program units were giving same error while full expending those. I deleted those 3 program units and re-created them. Now it is not showing me this memory error while full expanding all program units. I can now fully expand my full form.
But I am still getting this error while saving the changes when I am connected to database.
Please help.
Regards,

Hi Experts,
We are getting the same issue. Our form builder crashes once we open our custom form
in form builder.
Server shows:-
Forms 6.0 (Forms Runtime) Version 6.0.8.28.0 (Production)
Form Builder shows:-
Forms [32 Bit] Version 6.0.8.11.3 (Production)
How to upgrade the form builder version?
