How to use .peerToPeerDisabled = true ?

I have a question on the Flash Player 10.1 forum and I thought I might get more help here.
Here's the link to the question: http://forums.adobe.com/thread/563478?tstart=0
It pretty much pertains to how can I use the pure IP Multicast feature. I'd like to give it a try.
Thanks in advance.

when i clicked on the link above, it took me to that thread. however, the answer in that thread is now out-of-date.
at the time i answered that question, there were no shipping products that could send video stream IP multicast packets compatible with Flash Player. however, now (and for many years) Adobe Media Server can send IP multicast packets for video streams, that can be received by Flash Player.
when Flash Player joins a group with peerToPeerDisabled=true, it won't challenge the user with the "Peer Assisted Networking" permission box. this allows you to use the group NetStream APIs to receive a stream via pure IP multicast from a server (such as Adobe Media Server) without the user having to allow "Peer Assisted Networking". that's the only purpose for "peerToPeerDisabled=true".

Help - How to use kioskmode=true?

This is from a previous post - but I'm not sure what it means. - I've never iweb, but thought someone here might know the answer.
Your friend has disabled QT Pro saving by using the special html tags (kioskmode="true") in the page source.
His code also determines the "size" of the player window.
You'll need to dig through the page source code to find the URL to the .mov file and open it directly via QuickTime Player's "Open URL" feature.
This may allow saving and full screen playback.

If you want a backing file to be run while rendering a book, you should specify your file in Backing property of the book. Is that what you are trying to do?

How-to use Excel for the XML file input?

Hello all,
Following our discussion with Gerhard Steinhuber on the very nice tutorial from Horst Schaude , "How to upload mass data via XML File Input" , I am starting this new discussion.
In the comments section of this previous cited tutorial, Rufat Gadirov explains how to use a generated XML from Eclipse instead of your XSD file as your source in Excel.
However, in spite of all the instructions, I am still facing the same issue in Excel when I try to save my file as XML : "The XML maps in this workbook are not exportable".
What I try to do is to create one or more Sales Orders with multiple Items in it from a XML File Input, using excel to enter data.
The part with the File input is working (if I directly upload my file to the webDAV, it creates a sales order instance with multiple items).
The only missing part is the Excel data input that I cannot make work. Any help on this matter would be greatly appreciated.
Here is my XML file that I try to use as a source in Excel before inputing data from Excel:
<?xml version="1.0" encoding="UTF-8"?>

Hello Jacques-Antoine,
I suppose that as you have tried to construct a map from the schema, you have taken the elements from the List level down. In this case I also can't export the map.
But if you take the elements from the level MySalesOrderUploaded down, you'll get the exportable map (screenshots)

How to use an if statement in javascript code

Hello,
I have a batch processing script to search for text "employee signature" on each page in a multiple page file and to then list in the console any pages that do not have the "Employee Signature" text included.
The script is not yet functional as an if statement needs to be included.
Can anyone please advise how to use an if statement in javascript code?
var numpages = this.numPages;
for (var i=0; i < numpages; i++)
search.query("Employee Signature", "ActiveDoc");
console.println('Pages that do not include an employee signature: ' + this.pageNum +' ');
Any assistance will be most appreciated.

Thank you very much for your assistance try.
I have modified the code as suggested and the page numbers are now listing correctly, thank you, but....................,
The console lists every page as having an "employee signature" when there are pages in the document that do not have an employee signature.
The code (revised as follows) is not processing the "getPageNthWord part of the statement" in the console report?
Can you please advise where the code needs reworking?
var ckWords; // word pair to test
var bFound = false; // logical status of found words
// loop through pages
for (var i = 0; i < this.numPages; i++ ) {
   bFound = false; // set found flag to false
   numWords = this.getPageNumWords(i); // number of words on page
   // loop through the words on page
   for (var j = 0; j < numWords; j++) {
      // get word pair to test
      ckWords = this.getPageNthWord(i, j) + ' ' + this.getPageNthWord(i, j + 1); // test words
      // check to see if word pair is 'Employee' string is present
      if ( ckWord == "Employee") {
         bFound = true; // indicate found logical value
         console.println('Pages that includes an employee signature: ' + (i + 1) +' ');
         break; // no need to further test for this page
      } // end Employee Signature
   } // end word loop
   // test to see if words not found
   if(bFound == false) {
         console.println('Pages that do include an employee signature: ' + (i + 1) +' ');
    } // end not found on page
} // end page loop
Thank you

JNI - How to use the error reporting mechanism?

I've developed a C++ DLL which is loaded from a commercial Win32 application (not written by me) as a plug-in for external calculations. On its initialization the C++ DLL launches the Java VM via the JNI invocation interface. When the DLL functions are called by the application, they forward the calls to Java objects inside the Java VM, again via JNI invocation interface.
This works well, but I have encountered a weird error.
From Java I open a JFrame containing a JTextArea as small console for debug output messages. If I turn output to this debug console off (my printToConsole routine checks whether a boolean flag is set), the string concatenation operator may lead to a crash of the Java VM.
For example, if in one of the Java functions called from the
DLL via JNI invocation interface the following is the first statement,
it leads to a crash of the Java VM and the application that loaded the C++ proxy DLL.
String test=""+Math.random(); // String test not used later
Interestingly, if I comment this statement out, the Java code works fine WITHOUT any crash. I've already thought about potential races and synchronization issues in my code, but I don't see where this is the case. And the string concatenation error fails as well, if I insert sleep() statements in front of it and at other places in the code. However, if I turn on log messages printed to my JFrame debug console (containing a JTextArea), the String concatenation works without problems.
So maybe the JNI interface has a bug and affects the Java VM; I don't see where my JNI code is wrong.
One problem is that I do not get any stdout output, as the C++ proxy DLL is loaded by the Windows application, even if I start the Windows application from the DOS command line (under Windows).
Does anyone know how to use the error reporting mechanism?
http://java.sun.com/j2se/1.4.2/docs/guide/vm/error-handling.html
Is it possible that the JVM, when it crashes, writes debug information about the crash into a file instead of stdout/stderr?
My C++ proxy DLL was compiled in debug mode, but the commercial application (which loaded the DLL) is very likely not.
I do not know hot to find the reason why the String concatenation fails inside the Java function called from the C++ DLL via JNI.

Yes, I've initially thought about errors in the C++ code too. But the C++ code is actually very simple and short. It doesn't allocate anything on the C++ side. It allocates a couple of ByteBuffers inside the Java VM however via JNI invocation interface calls of env->NewDirectByteBuffer(). The native memory regions accessed via the ByteBuffers are allocated not by my own C++ code, but by the program that calls my DLL (the program is Metastock).
The interesting thing is that everything works fine if output to my debug console is enabled, which means that in the Java print routine getConsoleLoggingState() returns true and text is appended to the jTextArea.
static synchronized void print(String str)
{ MetaStockMonitor mMon=getInstance();
if ( mMon.getFileLoggingState() && mMon.logFileWriter!=null) {
mMon.logFileWriter.print(str);
mMon.logFileWriter.flush();
if ( mMon.getConsoleLoggingState() ) {
mMon.jTextArea1.append(str);
Only if output to the JTextArea is turned off (ie. getConsoleLoggingState()==false), the crash happens when the FIRST statement in the Java routine called via JNI invocation interface is a (useless) String concatenation operation, as described above.
String test=""+Math.random(); // String test not used later
Moreover, the crash happens BEFORE the allocated ByteBuffer objects are accessed in the Java code. But again, if console output is turned on, it works stable. If console output is turned off, it works when the (useless) String concatenation operation is removed in the Java routine called from C++.
I've already thought about potential races (regarding multiple threads), but this can be ruled out in my case. It almost appears as if the JVM can have problems when called by the invocation interface (I tested it with Java 1.4.2 b28).
All the calls between C++ and Java go ALWAYS in the direction from C++ code to Java. Unfortunately, there is no special JRE version with extensive logging capabilities to facilitate debugging. And the problem is not easily reproducible either.

Firefox crashed before I could load my previous session - how may I restore it? I have backed up relevant session files, but have no idea how to use them.

I was using Firefox shortly before deciding to restore my previous session (100+ tabs!), but the browser froze and went blank with the "Not Responding" label on top. This happened to me before, and I decided to just quit the session. I knew that I would lose the session I wanted, but I backed up the important session files found in the Mozilla directory (or at least whatever has "session" and "restore" in its name) while the browser was stuck (before quitting).
What I'd like to understand is HOW TO USE these files to get my session back. I've tried replacing the session files with the back-up copies to no avail. Once long ago I managed to recover a session successfully, but with Firefox constantly changing, I may have lost touch with this.
I use Firefox 34 and Windows 8.1, but I'll need others' help in identifying the session backup/restore files I need to use from the ones I backed up.
I believe that the "recovery.bak" is vital, because it contains the tab/page names I was viewing.
I would greatly appreciate whoever would help me in this, especially if they can teach me the proper methods to follow if this ever happens again (which most likely will!)

You can look at this post in this MozillaZine forum thread about inspecting a sessionstore file and possibly extract URLs.

How to use an authenticated user for a proxy call

Dear all,
I am currently working on a JEE application where the user needs to authenticate (for this I have configured the web.xml).
Now inside this application I need to do a proxy call to a PI webservice.
I would like to use the user credentials of the already logged in user in order to call the proxy.
What I don't want to do is to use a service user for the proxy call.
The code I am trying to call looks something like this:
     private IntegratedConfigurationIn getPort() throws Exception{
          IntegratedConfigurationIn port = null;
          try {
               IntegratedConfigurationInService service = null;
               service = new IntegratedConfigurationInService();
               port = (IntegratedConfigurationIn) service.getIntegratedConfigurationIn_Port();
              BindingProvider bp = (BindingProvider)port;
              bp.getRequestContext().put(BindingProvider.USERNAME_PROPERTY, user);
              bp.getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, password);
              if (url.length() != 0)
                   bp.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, url);
          catch (Exception ex){
               ex.printStackTrace();
          return port;
The examples I found to retrieve the userdata pointed to codes similar to this one:
public HttpServletRequest getHttpRequest() throws Exception {
          // Get runtime context
          Properties props = new Properties();
          props.put("domain", "true");
          Context initialContext = new InitialContext(props);
          ApplicationWebServiceContext wsContext = (ApplicationWebServiceContext) initialContext
                    .lookup(" /wsContext/ApplicationWebServiceContext");
          HttpServletRequest req = wsContext.getHttpServletRequest();
          return req;
com.sap.security.api.IUser sapUser = com.sap.security.api.UMFactory.getAuthenticator().getLoggedInUser(getHttpRequest(), null);
          IUser ep5User = com.sapportals.wcm.util.usermanagement.WPUMFactory.getUserFactory().getEP5User(sapUser);
Now I don't know how to bring it togehter and how to use an authenticated user for the BindingProvider.
I would appreciate any hints or ideas.

Peter,
from the first screenshot, what I understood is that, you are calling an inbound PI web service that is intended to create an integrated configuration object (this is used for whole lot of other reason completely) but not actually calling a development web service.
For this, you would have to generate your client classes from the WSDL provided by the PI developer for that particular service. Once you get those client classes generated, you could used the method provided in the other screenshot to extract the user and password and call the intended web service.

How to use one commandButton to execute two task in JSF

I have a form in JSF page which contains different faces components. These faces bind to ADF BC to insert one row in the database when the user press commandButton. Also I need to bind the value of one inputText in that form to managed bean to execute another task in the application when the user press the same commandButton.
The code of the inputText:
<h:inputText value="#{bindings.ProjectNumber.inputValue}"
id="pn"
size="10"
required="#{bindings.ProjectNumber.mandatory}">
The code of commandButton:
<h:commandButton actionListener="#{bindings.Commit.execute}"
value="Save"
disabled="#{bindings.Commit.actionEnabled}"/>
The managed bean is “findInspector”. I tried to insert inputHidden inside commandButton tag and assign the value of the inputText to the inputHidden as follows:
<h:commandButton actionListener="#{bindings.Commit.execute}"
value="Save"
disabled="#{bindings.Commit.actionEnabled}">
<h:inputHidden value="#{bindings.ProjectNumber.inputValue}" binding="#{findInspector.project}"/>
</h:commandButton>
But it was not work
Please how can I write the code to use the value of the inputText more than one time in the JSF(one to insert one row by using ADF BC and another to use the same value to bind to a managed bean) and how to use one commandButton to execute two task in JSF.
Thank you
Waheed

Yes I did
<managed-bean>
<description>The bean for get project No</description>
<managed-bean-name>projectBean</managed-bean-name>
<managed-bean-class>
mcscm.model.ProjectBean
</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>bindings</property-name>
<value>#{bindings}</value>
</managed-property>
</managed-bean>
Also I changed the method in the managed bean as follows:
public String commandButton_action() {
FacesContext fctx = FacesContext.getCurrentInstance();
ValueBinding vb = fctx.getApplication().createValueBinding("#{bindings}");
DCBindingContainer dcb = (DCBindingContainer) vb.getValue(fctx);
OperationBinding operation = (OperationBinding) dcb.get("projectNumber");
operation.execute();
return null;
where projectNumber is my method in the java class of the application module "TaskInformationImpl". I made this method to be accessed from outside of ADF BC.
I just create a sample code for projectNumber method for testing only as:
public void projectNumber (String data){
System.out.print(data);
In the page Pagedef file I added this :
<methodAction id="projectNumber"
InstanceName="TaskInformationDataControl.dataProvider"
DataControl="TaskInformationDataControl"
MethodName="projectNumber" RequiresUpdateModel="true"
Action="999" IsViewObjectMethod="false">
<NamedData NDName="data" NDValue = "#{bindings.ProjectNumber.inputValue}" NDType="java.lang.String"/>
After I did all of this I get a new error like:
javax.faces.FacesException: #{projectBean.commandButton_action}: javax.faces.el.EvaluationException: java.lang.ClassCastException: oracle.adfinternal.view.faces.model.binding.FacesCtrlAttrsBinding cannot be cast to oracle.adf.model.OperationBinding
Is it very difficult to do this in JDeveloper?. yes ADF BC provide me a lot of facilities, but when I want to do a specific task I face a lot of troubles

How to use execute query For a single record

Hi All,
I am working with oracle forms 10g, I have developed a custom form.
I the form user enter some data and click save in the menu and data get inserted into my table. Inside the insert statement i have hardcoded some values, Once data get inserted i cant able to see that values immediately in my text fields in my form.After requerying i can able to see the changes.
For example I have a text field called Status, and the field is display only field. At that time of insert i have hardcoded as "INCOMPLETE". Once the user enter the data in the form and click save the data get inserted in to my table but i cant able to see the status, after i requery my form i can able to see the status.
Here i do multi insert also.
This is my insert statement
BEGIN
First_Record;
LOOP
IF :BANK_GUARANTEE_BLK.CHECK_IN_OUT = 'Y'
THEN
XXBANK_GUARANTEE_HEADERS.XXBANK_GUARANTEE_INSERT;(this is my package, here i have written my insert statement)
--Execute_query;
END IF;
Exit when :System.Last_Record = 'TRUE';
Next_Record;
END LOOP;
END;
If user insert only one row and i gave Execute_query to refresh and bring the current data, but when i use execute_query Its brings up all the datas in the table.
Can any one tell me how to avoid this and how to use execute_query for a single record.
Thanks &regards
Srikkanth

Solved,
The solution is
set_block_property('LC_REQ_BLK',ONETIME_WHERE,'LC_PO_NUMBER='||:LC_REQ_BLK.LC_PO_NUMBER);
go_block('LC_REQ_BLK');
execute_query;
Works fine.

How to Use Transient View Objects to Store Session-level Global Variables

hi
Please consider section "40.8.5 How to Use Transient View Objects to Store Session-level Global Variables"
at http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/bcstatemgmt.htm#ADFFD19610
Based on this documentation I created the example application
at http://www.consideringred.com/files/oracle/2010/ProgrammaticalViewObjectAndRollbackApp-v0.01.zip
It behaves as show in the screencast at http://screencast.com/t/qDvSQCgpvYdd
Its Application Module has a Transient View Object instance "MyEmployeesContextVOVI", as master for the child View Object instance "EmpInCtxJobVI".
On rollback the Transient View Object instance keeps its row and attribute values.
Also when passivation and activation is forced (using jbo.ampool.doampooling=false ) the Transient View Object instance seems to keep its row and attribute values.
questions:
- (q1) Why does the expression #{bindings.MyEmployeesContextVOVIIterator.dataControl.transactionDirty} evaluate as true when a Transient View Object instance attribute value is changed (as shown in screencast at http://screencast.com/t/qDvSQCgpvYdd )?
- (q2) What would be a robust approach to make a Transient View Object instance more self-contained, and manage itself to have only one single row (per instance) at all times (and as such removing the dependency on the Application Module prepareSession() as documented in "5. Create an empty row in the view object when a new user begins using the application module.")?
many thanks
Jan Vervecken

Thanks for your reply Frank.
q1) Does sample 90 help ? http://blogs.oracle.com/smuenchadf/examples/
Yes, the sample from Steve Muench does help, "90. Avoiding Dirtying the ADF Model Transaction When Transient Attributes are Set [10.1.3] "
at http://blogs.oracle.com/smuenchadf/examples/#90
It does point out a difference in marking transactions dirty by different layers of the framework, "... When any attribute's value is changed through an ADFM binding, the ADFM-layer transaction is marked as dirty. ...".
This can be illustrate with a small change in the example application
at http://www.consideringred.com/files/oracle/2010/ProgrammaticalViewObjectAndRollbackApp-v0.02.zip
It now shows the result of both these expressions on the page ...
#{bindings.MyEmployeesContextVOVIIterator.dataControl.transactionDirty}
#{bindings.MyEmployeesContextVOVIIterator.dataControl.dataProvider.transaction.dirty}... where one can be true and the other false respectively.
See also the screencast at http://screencast.com/t/k8vgNqdKgD
Similar to the sample from Steve Muench, another modification to the example application introduces MyCustomADFBCDataControl
at http://www.consideringred.com/files/oracle/2010/ProgrammaticalViewObjectAndRollbackApp-v0.03.zip
public class MyCustomADFBCDataControl
extends JUApplication
@Override
public void setTransactionModified()
    ApplicationModule vApplicationModule = (ApplicationModule)getDataProvider();
    Transaction vTransaction = vApplicationModule.getTransaction();
    if (vTransaction.isDirty())
      super.setTransactionModified();
}Resulting in what seems to be more consistent/expected transaction (dirty) information,
see also the screencast at http://screencast.com/t/756yCs1L1
Any feedback on why the ADF Model layer is so eager to mark a transaction dirty is always welcome.
Currently, question (q2) remains.
regards
Jan

How to use multiple selection parameters in the data model

Hi, after have looked all the previous threads about how to use multiple selection parameters , I still have a problem;
I'm using Oracle BI Publisher 10.1.3.3.2 and I'm tried to define more than one multiple selection parameters inside the data template;
Inside a simple SQL queries they work perfectly....but inside the data template I have errors.
My data template is the following (it's very simple...I am just testing how the parameters work):
<dataTemplate name="Test" defaultPackage="bip_departments_2_parameters">
<parameters>
<parameter name="p_dep_2_param" include_in_output="false" datatype="character"/>
<parameter name="p_loc_1_param" include_in_output="false" datatype="character"/>
</parameters>
<dataTrigger name="beforeReport" source="bip_departments_2_parameters.beforeReportTrigger"/>
<dataQuery>
<sqlStatement name="Q2">
<![CDATA[
select deptno, dname,loc
from dept
&p_where_clause
]]>
</sqlStatement>
</dataQuery>
<dataStructure>
<group name="G_DEPT" source="Q2">
<element name="deptno" value="deptno"/>
<element name="dname" value="dname"/>
<element name="loc" value="loc"/>
</group>
</dataStructure>
</dataTemplate>
The 2 parameters are based on these LOV:
1) select distinct dname from dept (p_dep_2_param)
2) select distinct loc from dept (p_loc_1_param)
and both of them have checked the "Multiple selection" and "Can select all" boxes
The package I created, in order to use the lexical refence is:
CREATE OR REPLACE package SCOTT.bip_departments_2_parameters
as
p_dep_2_param varchar2(14);
p_loc_1_param varchar2(20);
p_where_clause varchar2(100);
function beforereporttrigger
return boolean;
end bip_departments_2_parameters;
CREATE OR REPLACE package body SCOTT.bip_departments_2_parameters
as
function beforereporttrigger
return boolean
is
l_return boolean := true;
begin
if (p_dep_2_param is not null) --and (p_loc_1_param is not null)
then
p_where_clause := 'where (dname in (' || replace (p_dep_1_param, '''') || ') and loc in (' || replace (p_loc_1_param, '''') || '))';
else
p_where_clause := 'where 1=1';
end if;
return (l_return);
end beforereporttrigger;
end bip_departments_2_parameters;
As you see, I tried to have only one p_where_clause (with more than one parameter inside)....but it doesn't work...
Using only the first parameter (based on deptno (which is number), the p_where_clause is: p_where_clause := 'where (deptno in (' || replace (p_dep_2_param, '''') || '))';
it works perfectly....
Now I don't know if the problem is the datatype, but I noticed that with a single parameter (deptno is number), the lexical refence (inside the data template) works.....with a varchar parameter it doesn't work....
So my questions are these:
1) how can I define the p_where_clause (inside the package) with a single varchar parameter (for example, the department location name)
2) how can I define the p_where_clause using more than one parameter (for example, the department location name and the department name) not number.
Thanks in advance for any suggestion
Alex

Alex,
the missing thing in your example is the fact, that if only one value is selected, the parameter has exact this value like BOSTON. If you choose more than one value, the parameter includes the *'*, so that it looks like *'BOSTON','NEW YORK'*. So you need to check in the package, if there's a *,* in the parameter or not. If yes there's more than one value, if not it's only one value or it's null.
So change your package to (you need to expand your variables)
create or replace package bip_departments_2_parameters
as
p_dep_2_param varchar2(1000);
p_loc_1_param varchar2(1000);
p_where_clause varchar2(1000);
function beforereporttrigger
return boolean;
end bip_departments_2_parameters;
create or replace package body bip_departments_2_parameters
as
function beforereporttrigger
return boolean
is
l_return boolean := true;
begin
p_where_clause := ' ';
if p_dep_2_param is not null then
if instr(p_dep_2_param,',')>0 then
p_where_clause := 'WHERE DNAME in ('||p_dep_2_param||')';
else
p_where_clause := 'WHERE DNAME = '''||p_dep_2_param||'''';
end if;
if p_loc_1_param is not null then
if instr(p_loc_1_param,',')>0 then
p_where_clause := p_where_clause || ' AND LOC IN ('||p_loc_1_param||')';
else
p_where_clause := p_where_clause || ' AND LOC = '''||p_loc_1_param||'''';
end if;
end if;
else
if p_loc_1_param is not null then
if instr(p_loc_1_param,',')>0 then
p_where_clause := p_where_clause || 'WHERE LOC in ('||p_loc_1_param||')';
else
p_where_clause := p_where_clause || 'WHERE LOC = '''||p_loc_1_param||'''';
end if;
end if;
end if;
return (l_return);
end beforereporttrigger;
end bip_departments_2_parameters;
I've written a similar example at http://www.oracle.com/global/de/community/bip/tipps/Dynamische_Queries/index.html ... but it's in german.

How to use methods when objects stored in a linked list?

Hi friend:
I stored a series of objects of certain class inside a linked list. When I get one of them out of the list, I want to use the instance method associated with this object. However, the complier only allow me to treat this object as general object, ( of Object Class), as a result I can't use instance methods which are associated with this object. Can someone tell me how to use the methods associated with the objects which are stored inside a linked list?
Here is my code:
import java.util.*;
public class QueueW
     LinkedList qList;
     public QueueW(Collection s) //Constructor of QuequW Class
          qList = new LinkedList(s); //Declare an object linked list
     public void addWaiting(WaitingList w)
     boolean result = qList.isEmpty(); //true if list contains no elements
          if (result)
          qList.addFirst(w);
          else
          qList.add(w);
     public int printCid()
     Object d = qList.getFirst(); // the complier doesn't allow me to treat d as a object of waitingList class
          int n = d.getCid(); // so I use "Object d"
     return n; // yet object can't use getCid() method, so I got error in "int n = d.getCid()"
     public void removeWaiting(WaitingList w)
     qList.removeFirst();
class WaitingList
int cusmNo;
String cusmName;
int cid;
private static int id_count = 0;
     /* constructor */
     public WaitingList(int c, String cN)
     cusmNo = c;
     cusmName = cN;
     cid = ++id_count;
     public int getCid() //this is the method I want to use
     return cid;

Use casting. In other words, cat the object taken from the collection to the correct type and call your method.
   HashMap map = /* ... */;
   map.put(someKey, myObject);
   ((MyClass)(map.get(someKey)).myMethod();Chuck
