EntityManager.findEntities(arg0, arg1, arg2, arg3, arg4, arg5, arg6)
Has anyone used the Entity Manager findEntities or findChildEntities method. I am trying to find out what each of the input parameters represent.
There is no documentation for EntityManager in the OIM API documentation.
Thanks in advance
Thank you very much for that and the quick response.
I am hoping I can fill in the description for these parameters. I got the description from the oracle.iam.identity.usermgmt.api.UserManager.Search() function, so they more or less they should match the description for the entity manager.findentities() parameters.
The only thing missing here would be the EntityType which can be "User" this is to retrieve a user entity. or you can do orchestration.getTarget().getType() if you have the orchestration object
Parameters:
criteria - The search criteria based on which entries will be retrieved from the backend. The SearchCriteria Operators supported are AND, OR, NOT, GREATER_THAN, GREATER_EQUAL, LESS_THAN, LESS_EQUAL, EQUAL and NOT_EQUAL. For additional comparisons like contains the SearchCriteria Operator will be EQUAL with value to be searched will be '*<value>*'
retAttrs - The list of attributes which are to be returned for each user.
There are four configuration parameters. STARTROW, ENDROW, SORTEDBY and SORTORDER.
The STARTROW and ENDROW search configuration parameters indicates which subset of the complete search result is to be fetched.
The SORTEDBY search configuration parameter indicates the attribute on which search result is to be sorted.
The SORTORDER search configuration parameter indicates the order of sorting. There are two possible values for this parameter. To sort the result in ascending order use SortOrder.ASCENDING and to sort the result in descending order use SortOrder.DESCENDING. This parameter is optional and is set to SortOrder.ASCENDING by default.
Returns:
the list of users which matched the search criteria. This list is filtered based on the attribute and entity permissions of the logged-in User.

Network.addNode (arg1,arg2,arg3) is there a bug in Spatial Java API ?
Hi
when I try to add a Node on a Link to the Network - I'm really confused. I have a LinearLineString {0 0 10 0). When I try to add a Node on the position (2,0) my first new Link have the right coordinates (0,0,2,0) but the second new link have the coordinates (2,0,8,0) when I expected (2,0,10,0)?
maybe somebody have any idea?

ANE function parameters display as arg0, arg1, etc. how do I fix this?
I am creating an ANE and all my functions that take parameters show them as arg0, arg1, arg2, etc..
for example:
ShowAlert(arg0:String, arg1:String, arg2:String = "Ok", arg3:Array = null)
when it should be
ShowAlert(title:String, message:String, defaultButtonText:String = "Ok", additionalButtons:Array = null)
I did some searching and the only thing I was able to find was this:
By default, these are defined as arg0 and arg1, but you can give them more descriptive names. Change the call() function definition to look like this:
public FREObject call(FREContext context, FREObject[] passedArgs)
from http://www.adobe.com/devnet/air/articles/developing-native-extensions-air.html
hrm..
I assume it's using flex (as pretty much everyone else is these days - I should get around to learning that) but I am using Flash Pro.
Anyway, I don't really understand what he meant, so I started reading the rest of the document and I saw this line:
Set the superclass to com.adobe.fre.FREContext.
Hrm...
Does this mean I am supposed my ANE is supposed to extend that? Right now, it's extending EventDispatcher.
Regardless, can someone clarrify what he means, or what I am supposed to do to get my parameters appearing correctly?It does look like you want to extend FREContext.

Can WLW display the real names of method parameters, not arg0, arg1...
Hello
I am new to Java development and as I used to work with MS.NET usually rely on parameter names, so that I don't have to read documentations each time I use a method. However I noticed that WLW replaces the names of method parameters with arg0, arg1, arg2 etc. Is there a way to somehow make WLW display the real argument names and not those argX strings?
Thanks in advance.

EJB model showing arg1 , arg2 etc as input parameter attributes
Hi All ,
I am working on EJB models. I have done all required settings at EJB session and application dc and deployed EJB Dcs
successfully. When i am adding application dc as used dc i can see public part which i have created for EJB model. when i create EJB model my input parameterts are not showing exact names. they are shown as agr1 ,arg2 etc. i have worked earlier
on EJB models but never faced such issue. What can be reason for this? How to resolve this?

* The following describes the DLL functions that are made available
* through this ORA_FFI implementation:
Function Purpose
BiOpenMonPrinter Get a handle on a printer.
Parameters
p_Type --int: 1 if p_Name is a port, 2 if a printer name.
,p_Name --varchar2: the port of printer name to open.
Return printer identifier number (>0) on success, < 0 on failure.
BiCloseMonPrinter Close the monitor on the printer.
Parameters
p_Handle --int: The numerical printer handle returned from BiOpenMonPrinter.
Return 0 on success, < 0 on failure.
BiGetStatus Returns the status of the printer.
Parameters
p_Handle --int: The numerical printer handle returned from BiOpenMonPrinter.
,p_Status OUT --long: The status of the printer (use AND bitwise operator to test for statuses).
Return 0 on success, < 0 on failure.
BiDirectIO Sends data to and Reads data from the printer. Use BiDirectIOEx if more that 255 chars are to be written/read.
Parameters
p_Handle --int: The numerical printer handle returned from BiOpenMonPrinter.

END;Hi Duncan,
Thanks for the response. Beyond the problem you pointed out I found that the "open server" command is requiring a window handle parameter, even though it isn't used by the program. I talked with Oracle Support and it turns out that even if the window handle isn't used, it's existence makes it not work with the current version of webutil.
The program I am working with also has a COM interface, so I decided to back up and redo the interface using webutil OLE2. I've got it working now, just a little more polishing to do.
Thanks again for the help.

nullHi,
Dont use private API's as its not feasible to use as AMG.
Use pa_project_pub.update_project API where u can pass class codes as record type.

Help with a basic dbx question
Solaris 10. DBX'ing a core file that was not compiled with any debugging information. When you do a basic "where", you typically get:
[1] someFile::someFunction(arg1, arg2, arg3, arg4, arg5, arg6) at 0x5ab32x
Can someone tell me what each of the addresses for the args above are? And what the "at 0x...." is ?
I am trying to examine the arguments passed into the functions using "examine addr" but having difficulty.
ThanksWithout any debugging information, dbx cannot know how many arguments, or of what type, the function has.
It displays the contents of the stack where the first 6 arguments would be if the registers were spilled, assuming that each argument was one word. Since the actual arguments might not be one word each, and since the registers might not have been spilled, the values displayed don't always have any significance. (If the function has fewer than 6 arguments, the remaining values have no significance.)
The 0x5ab32x looks like a copying error. Dbx shows the (hex) address where the program crashed. The trailing x cannot be correct.
You can get a disassembly starting at the function's address, or at some point ahead of the address shown, and try to match it to the source code. -
Trying to add a listener to a JComboBox in a JTable
Hi all.
I have a little problem which I can't resolve.
I made a program in which I create a table using a class which extends JTable (but this isn't the point with the problem, I think. It's only for rendering purposes)
In this table I put various types of items (such as Strings, JButton, JComboBox). I have no problem with the visualization of them, but the problem is with the listener for the combo boxes. I created a listener of my own and registered it in the constructor of the combo box editor, but when I change a value it's never fired. Can someone please help me?
Here's some code which can help understanding the problem
Combo box editor:
public class MyComboBoxEditor extends DefaultCellEditor{
public MyComboBoxEditor(JTableX _tabellaDiAppartenenza) {
super(new JComboBox());
(JComboBox)super.editorComponent).addItemListener(new MyItemListener((JComboBox)super.editorComponent));
public Component getTableCellEditorComponent(JTable arg0, Object arg1, boolean arg2, int arg3, int arg4) {
String elementi[]=new String[((JComboBox)arg1).getItemCount()];
for(int i=0;i<((JComboBox)arg1).getItemCount();i++){
elementi=(String)((JComboBox)arg1).getItemAt(i);
super.editorComponent=new JComboBox(elementi);
return super.getTableCellEditorComponent(arg0, arg1, arg2, arg3, arg4);
}combo box listener:public class MyItemListener implements ItemListener{
private JComboBox combo;
public MyItemListener(JComboBox object){
combo=object;
public void itemStateChanged(ItemEvent arg0) {
int changeEvent = arg0.getStateChange();
if(changeEvent==ItemEvent.SELECTED){
Object value=arg0.getItem();
combo.setSelectedItem(value);
}table:public class JTableX extends JTable{
protected MyCellEditorModel myCellEditorModel;
public JTableX(MyDataModel tm){
super(tm);
Object ge = defaultEditorsByColumnClass.get(Boolean.class);
DefaultCellEditor dce = (DefaultCellEditor)ge;
dce.setClickCountToStart(0);
MyButtonEditor mbe = new MyButtonEditor(new JCheckBox("Bottone"), this);
mbe.setClickCountToStart(0);
MyComboBoxEditor mcbe = new MyComboBoxEditor(this);
mcbe.setClickCountToStart(0);
defaultEditorsByColumnClass.clear();
Hashtable cellEditors = new Hashtable();
cellEditors.put(JButton.class, mbe);
cellEditors.put(JComboBox.class, mcbe);
cellEditors.put(Boolean.class, dce);
this.defaultRenderersByColumnClass.put(JButton.class, new MyButtonRenderer());
this.defaultRenderersByColumnClass.put(JComboBox.class, new MyComboBoxRenderer());
defaultEditorsByColumnClass.put(Object.class, new MyCellEditorModel1(cellEditors));
public TableCellEditor getCellEditor(int row, int col){
if(myCellEditorModel!=null) return myCellEditorModel;
return super.getCellEditor(row,col);
public TableCellRenderer getCellRenderer(int row, int column) {
Object value = getValueAt(row,column);
if (value !=null) {
return getDefaultRenderer(value.getClass());
return super.getCellRenderer(row,column);
public void setCellEditor(MyCellEditorModel anEditor) {
myCellEditorModel = anEditor;
}Hoping the code is enough to understand the problem, I thanks all for watching and reading the post and for the future answeres.
Bye all.super.editorComponent=new JComboBox(elementi);You create a new combo box each call to getTableCellEditComponent() (overriding the one of the constructor), but you aren't adding a ItemListener to it.

Facing Issue With Oracle SOA Suite 11.1.1.3.0
Hi All,
I am facing some issues with ORACLE SOA SUITE 11.1.1.3.0.
Hope you people can help us out.
Please find the issue details below along with all the relevant information’s
I have following SOA suite installation at my server:
Oracle 10g Express Edition Universal 10.2.0.1
RCU 11.1.1.3.3
Web Logic Server 10.3.3.0
SOA suite 11.1.1.3.0
JDeveloper 11.1.1.3.0
The first thing what I have done is created a web service and deployed it to server without any issue.
After that I created proxy client for that service and accessed it successfully from the client end.
Till here no issue occurs.
After that I applied few policies on top of web service and deployed it to server.
The policy I had chosen was “oracle/wss_username_token_service_policy” [coming under OWSM policies list]
While deploying there was no issue, all went well.
2nd step I had created client using “oracle/wss_username_token_client_policy” policy which is counter part of above policy and tried to access the web service but failed.
I have followed this blog:
[http://biemond.blogspot.com/2010/08/things-you-need-to-do-for-owsm-11g.html ]
Please have a look on service and client code:
Service Code:
package Demo_ScoreCard;
import javax.jws.WebService;
import weblogic.wsee.jws.jaxws.owsm.SecurityPolicy;
@WebService
@SecurityPolicy(uri = "oracle/wss_username_token_service_policy")
public class ScoreCardWithPolicy {
public double getPercentageWithPolicy(double markEng,double markMath,double markHindi,double markScience,double markSsc)
double result;
result= ((markEng+markHindi+markMath+markScience+markSsc)/500)*100;
return result;
Client Code:
package com.tec.proxy.client;
import java.util.Map;
import javax.xml.ws.BindingProvider;
import javax.xml.ws.WebServiceRef;
import weblogic.wsee.jws.jaxws.owsm.SecurityPolicyFeature;
public class ScoreCardWithPolicyPortClient {
@WebServiceRef
private static ScoreCardWithPolicyService scoreCardWithPolicyService;
public static void main(String[] args) {
scoreCardWithPolicyService = new ScoreCardWithPolicyService();
SecurityPolicyFeature[] securityFeatures =new SecurityPolicyFeature[] { new SecurityPolicyFeature("oracle/wss_http_token_client_policy") };
ScoreCardWithPolicy scoreCardWithPolicy =scoreCardWithPolicyService.getScoreCardWithPolicyPort(securityFeatures);
Map<String, Object> reqContext =((BindingProvider)scoreCardWithPolicy).getRequestContext();
reqContext.put(BindingProvider.USERNAME_PROPERTY, "testclient");
reqContext.put(BindingProvider.PASSWORD_PROPERTY, "test12345"); // I have added this to the myrealm from console under security realms
double arg1 = 77.2;
double arg2 = 79.2;
double arg3 = 77.2;
double arg4 = 76.2;
double arg5 = 67.2;
double clientResult =scoreCardWithPolicy.getPercentageWithPolicy(arg1, arg2, arg3, arg4,arg5);
System.out.println("clientResult with policy =====> " + clientResult);
Error Log:

Process exited with exit code 1.
Not getting any help from any blog. Just wondering why this error is coming. I would be glad if you can help us in this regard.
Apart from above issue I have few queries like:
1.What is difference between OWSM policies and WLS policies?
2.Are these the only policies we can apply on top of services?
3.If some one wants to configure his own custom policies than what need to be done
4.Could anyone please provide some useful links to implement ENCYPTION and SIGNATURE on top of web services?
5.And If I am not wrong, I guess Oracle Service BUS OSB 11.1.1.3 has been removed from the main download link and version 11.1.1.4 has been provided. Is it
compatible with SOA suite 11.1.1.3.0? If not where can I get OSB 11.1.1.3?
Looking forward to hear from you people.
Thanks
Arvind

Edited by: user8490871 on Apr 15, 2011 12:53 AMHi,
I don't know why u get an error. Here are answers for additional questions:
1. OWSM policies are for web services. WLS policies are based on Java EE security. They are used to protect resources e.g. URL, EJB
2. I don't know about other policies
3. See http://download.oracle.com/docs/cd/E14571_01/web.1111/e13713/owsm_appendix.htm#CHDCHFBH
4. See http://download.oracle.com/docs/cd/E14571_01/security.1111/e10037/toc.htm
5. I can see OSB 11.1.1.3 download link here

Election problem after repeated split-brains with two nodes
Hi
I'm using a customized source based on BDB-5.1.19 (excxx_repquote)
with two site one - MASTER and the other SLAVE...
nsite=2
ack=quorum
- the master is writing to quotedb at a rate of 10 txn per sec
- the test consist to isolate the client from the master (split brain) and reconnect it after a random time include from 1sec to 10sec
the test run well about 10 times but at a moment the process slave receive DB_EVENT_REP_ELECTION_FAILED
and the master enter in election mode and never exit from the CLIENT mode. I must say that to freeze the client I decide to kill me (kill -9 my pid) when I receive such event...
here is the verbose log on the master...

* These pieces of information are expressed by the following flags.
* -h home (required; h stands for home directory)
* -l host:port (required; l stands for local)
* -C or -M (optional; start up as client or master)
* -r host:port (optional; r stands for remote; any number of these may be
* specified)
* -R host:port (optional; R stands for remote peer; only one of these may
* be specified)
* -a all|quorum (optional; a stands for ack policy)
* -b (optional; b stands for bulk)
* -n nsites (optional; number of sites in replication group; defaults to 0

[JS,AS,CS3]running javascript in bridge from applescript
Sorry for the cryptic subject description, and you might think this is a bit off topic, but i hope you could shed some light on this.
I need to execute a Javascript in Bridge from an applsecript using an Applescript. Bridge only has one AS command: do javascript with arguments.
My testtude looks like this:
set myJS to "
alert(arguments[0].toString());
alert(arguments[1].toString());
alert(arguments[2].toString());
alert(arguments[3].toString());
alert(arguments[4][0].toString());
set arg1 to 12
set arg2 to "some text"
set arg3 to "'some single quoted text'"
set arg4 to "\"some double quoted text\""
set arg5 to {1, 2, 3, "a", "b", "c"}
tell application "Bridge CS3"
do javascript myJS with arguments {arg1, arg2, arg3, arg4, arg5}
end tell
--tell application "Adobe Photoshop CS3"
-- do javascript myJS with arguments {arg1,arg2,arg3,arg4,arg5}
--end tell
You would expect a series of dialogs to appear with the content of the arguments, but you'll get nothing! If you omit the '[0]', you'll get any numerical value, but all strings, however they are quoted, are ignored.
Strange.
Stranger still is, that if do the exact same thing in Photoshop, it works like a charm and you can pass any kind of data as argument.
Any ideas on what's going on?
Thanks!Here is my AS script from Xcode project:
Some text is in Russian don't mind it. Most important that this is a
working example.

Edited by: 892270 on 16-Aug-2012 08:46User, please always tell us your jdev version as the solution might depend on it.
Instead of posting some code, can you please elaborate on the use case? From the code I don'T understand what you try to do. Data (file) uploaded through the af:inputFile is binary. The file may only be a text file, but it might be an image. The inputFile doen not know as it only represents the data stream send from the client.
In you code I don't see that you actually read the data from the stream, neither do I see any action on the stream. Can you describe what you mean by
but I can not make it work ...You may read http://tompeez.wordpress.com/2011/11/26/jdev11-1-2-1-0-handling-imagesfiles-in-adf-part-1/ for more info about file handling in ADF

Using Runtime.exec to execute Java.exe
I am trying to use Runtime.exec to spawn a thread that runs java.exe, but havn't had any luck. I have two versions of code, the first one works (example 1), but I want to eliminate the use of "cmd /c" to keep system independance. The second example (example 2) does not work. Both versions work if invoked from the command line. I'm running Win2000. Any Ideas?
Example 1:
aProcess = aRuntime.exec("cmd /c java.exe
-cp "<MyClassPathHere>" <arg1> <arg2> <arg3> <arg4> <arg5>");
Example 2:
aProcess = aRuntime.exec("java.exe
-cp "MyClassPathHere" <arg1> <arg2> <arg3> <arg4> <arg5>");I think you mix two concepts: "threads" and "processes". A "thread" is a thread of execution inside the VM, but you want to actually start a new VM in a new process, which is an OS level thing, right?
I've tried Idea 2 also, same result: works if
i specify cmd c/, doesn't if I don't.It should work if java.exe is in your path... are you taking care of the standard streams of your process?
Maybe you are looking for
