Hi All
i have created a database link as following steps
create public database link testtutor.matpl
connect to tutor identified by ******
using 'testtutor';
where tutor schema is on remote server.
SQL> alter system set global_names = false;
System altered.
link is working fine with select statement but producing error
when i try to describe a remote table
SQL> select count(1) from [email protected];
COUNT(1)
114
SQL> desc [email protected];
ERROR:

RMI and Threads: Calling wait() on a remote object

I created a counter as a remote object.
Multiple clients are displaying the counter value.
If one of the clients increments the counter, I want the displayed counter value on every client to be updated to the new value (of the counter on the server).
Therefore every client starts a new thread to "listen" for changes of the countervalue. I wanted to call the wait() method on the remote object (the remote counter). But i think it will be called on the stub instead of on the actual remote object.
Therefore i created a extra method waitForChange() on the remote object.
public void waitForChange() throws RemoteException, InterruptedException {
     synchronized(this) {
          wait();
This method only calls the wait() method. Now I'm sure it's called on the remote object and not on the stub.
This works, but my question is: is there a better way to do this?

}This is just a little test. Actually I want to notify clients of changes in data displayed in a Table. If one client saves one record of the data, i want the new record to be displayed immediatly on all clients that are viewing the same data.

I've been doing some reading about RMI and callback.
As I understand it, there's a remote object is running on the client now as wel. And the server makes a call to the client.
But now the server makes a call to one client.
And the point is, I want all clients to be updated with the new value.
Does this mean, I have to keep a list with references to all clients connected to the server?
I my code the notifyAll() method causes all waiting Threads (running on several clients) to wake up and do something (getting the new counter value).

Remote object trying to return another remote object and a ClassCastExcepti

I have a server running with a TreeModel (the tree model implements Remote). I also have the the TreeNodes all linked together on the server. Now, I can get to the TreeModel on the server and the root node of the remote tree model.
treeModelStub = (treeModelIface)Naming.lookup(url+"remoteTM"); //works
rootStub = (remoteTreeNodeIface)treeModelStub.getRoot(); //works. The call to getRoot returns Object
But when I call
remoteTreeNodeIface aChild = (remoteTreeNodeIface)rootStub.getChildAt(index) //Does not work. "Exception in thread "main" java.lang.ClassCastException
at remoteTreeNode_Stub.getChildAt(Unknown Source)
The remote tree node method getChildAt returns TreeNode because the class implements TreeNode:
public class remoteTreeNode extends UnicastRemoteObject implements rdcaDataIface, Comparable, TreeNode {
public TreeNode getChildAt(int idx) {
System.out.println("DEBUG: class is "+this.getClass()); // class is remoteTreeNode
return (remoteTreeNode)children.get(idx);
The remote interface is defined as:
public interface rdcaDataIface extends java.rmi.Remote {
public TreeNode getChildAt(int idx) throws RemoteException;
Any ideas why this does not work. Why can a remote object of type Object be returned just fine, but a TreeNode not be returned?

Remote Object - not able to get the returned value from java method

     Hi ,
I am developing one sample flex aplication that connects to the java code and displays the returned value from the
java method in flex client. Here I am able to invoke the java method but not able to collect the returned value.
lastResult is giving null . I am able to see the sysout messages in server console.
I am using flex 3.2 and blazeds server and java 1.5
Here is the code what I have written.

Please help me .

You are not able to get the returned value because if you see the Remote object help you will realise you have to use result="resultfn()" and fault = "faultfn()"
In this you define what you wish to do.
More importantly in the remote object you need to define which method you wish to call using the method class like this
<mx:RemoteObject id="remoteObj" destination="sro" result="r1" fault="f1" >
     <Method name="javaMethodName" result="r2" fault="f2"/>
<mx:RemoteObject>
r2 is the function where you get the result back from java and can use it to send the alert.

Two remote objects calls on the same php class

Hi to all,
I've encountered a strange issue while developing with remote objects.
I've a mxml component with an init() method inside which is called by a menu.
When the init() method is called it makes 7 remote object calls which are bound to some components' dataprovider.
Among this calls I've got 2 remote object which refer to the same remote class. This because I have to call the class twice and the bind the result to two different combobox. Below you find the code:
<mx:RemoteObject id="myFile" source="myRemoteClass" destination="amfphp" showBusyCursor="true" makeObjectsBindable="true" fault="traceFault(event)"/>
<mx:RemoteObject id="myXls" source="myRemoteClass" destination="amfphp" showBusyCursor="true" makeObjectsBindable="true" fault="traceFault(event)"/>
in the init function I make this calls:
myFile.listDir("dir_1")
myXls.listDir("dir_2")
then in the mxml code I bound the result of myFile to combobox1 and the result of myXls on combobox2.
The problem arise when I call the myXls' listDir method. When I call it I receive the following error:
code:
Client.Error.DeliveryInDoubt
Message:
Channel disconnected
Detail:
Channel disconnected before an acknowledgement was received
The strange thing is that not only the myXls object returns this error, but also all the other 6 remote object return the same error above.
I'm not sure, but I guess that the error could be caused by the two remote object which call the same php remote class. If I comment one of the two calls everything works fine.
Do you have any suggestion about?
Thanks!!
Bye

Hi Jan.
1) We have the 2 VO, each with 3 rows to fill in data. What I mean is that when i just fill in all the fields for the first row of the first VO, and the value of one of these fields is bigger than 50, then after the exception is thrown and the message is displayed, the fields for the first VO are duplicated and shown in the second VO as if the user had inserted them.
2) We tried yesterday the validateEntity and a Method and Atributte Validator approaches after reading that white paper with the same results.
The validation is correctly done using any of the those methods.
I will try to reproduce this issue with the HR schema.
Thanks in advance once again.

Exporting two remote objects on the same port

Hi,
I would like to export two remote objects on the same host, same port and bind them with different service names.
There is no problem when I do that from the same Java program.
But when I export and bind an object from a Java program 1, I cannot do the same with the second (and similar) Java program 2. This is the stack trace of my Exception:
java.rmi.server.ExportException: Port already in use: 50040; nested exception is:

It should work in any version of Java as long as the server socket factories are null or equal according to Object.equals() or its override in the SSF.equals() method if any. Which needs to be present and needs to take the form:
public boolean equals(Object object)
return object != null && object.getClass() == this.getClass();
}with further tests if the server socket factories have additional state.

PL/SQL: ORA-04052: error occurred when looking up remote object.

Hi All,
I'm getting the following error message while executing a PL/SQL Block.
PL/SQL: ORA-04052: error occurred when looking up remote object UPLDUSER.filestatushistory@FTS
ORA-00604: error occurred at recursive SQL level 1

ORA-02063: preceding line from FTSStatement
declare
v_coun number;
begin
select count(*) into v_coun
from updluser.filestatushistory@fts;
end;Back ground of the situation as follows,
My DataBase version 10.2.0.3 DB Name :DB1
Table Owner : UPLDUSER
Table Name : FILESTATUSHISTORY
I have a report user on the same database and I have grant all on the above table to report user
Report User : RPT_FTS
SQL> GRANT ALL ON FILESTATUSHISTORY_V TO RPT_FTS;Now Please find the below database details where I'm getting subjected error.
Database version : 9.2.0.8
DB Name : DB2
User Name : RPT_REPORTS
I Have create a dblink from RPT_REPORTS to RPT_FTS on DB1 and the dblink works fine. But getting the above error while running it.
but When I do the same other 10.2.0.3 db , the above PL/SQL block works fine without any problem.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Now the strange about this is that I have Created a new table on DB1 db like below;
SQL> CREATE TABLE UPLDUSER.ABC AS SELECT * FROM FILESTATUSHISTORY;and retry my code on DB2 (9.2.0.8) after changing the table to ABC and it worked. Now I don't know whats wrong with a original table(FILESTATUSHISTORY).
To over come the problem and a work-a-round method I create a view on the DB1 (RPT_FTS) like the below
SQL> CREATE VIEW FILESTATUSHISTORY AS SELECT * FROM UPLDUSER.FILESTATUSHISTORY;and was able to run the PL/SQL block Remotely.
Just wants To know what whould have been the cause for this .

Trying to create a local instance of the remote object

Hi,
I have a ClassA on which I need to be able to invoke RMI calls. Problem is the interface which ClassA implements does not throw exceptions. To get around this problem I have created a wrapper class ClassWrap which has a ClassA attribute and calls made to ClassWrap are directed to this ClassA object. A facade type design I think it's called.
ClassWrap implements Remote so it can be used as a Remote object.
When I create an instance of ClassWrap and deploy it on a server, my client has no problem communicating with the remote ClassWrap object via a remote stub ClassWrap_Stub.
Problem is I also want my client to be able to use a local instance of ClassWrap. Whan I try to create an instance of ClassWrap in my client I get a remote Exception ... but !! when I have a ClassWrap_Stub object in my classpath then there is no problem creating a ClassWrap object.
Any ideas why this happens?

What you are trying to do should work just fine. Do you have the wrapper class file in your client jar?

How does the remote object connect to the correct host

i have had a small doubt on how the remote reference manages to find the correct host to call the subsequent methods after a sucessful lookup.
given a rebind or bind to the registry, the registry only stores the alias and the remote reference, now imagine a client calling a lookup on the registry would only get the remote reference, and not in which machine the remote object is found.
what i wanted to know is how does the client or atleast the remote reference returned by the registry correctly connects to the machine where the remote object is located. i dont think its stored in the stub bcos the stub is a complie time stuff.
i would be pleased to have a comprehensive answer for this.

The membership in the group communication framework is always accurate and upto date.Up to date to the moment when you check. Not up to date to the moment when you make the RMI call.
i could basically chk if this ip is available in the membership list.Complete waste of time. It doesn't matter what you check ahead of time, you are still trying to predict the future.
And you still have to deal with ConnectException etc from the actual remote method call. And the way you will deal with that in your situation is exactly the same as what you were going to do if your ahead-of-time check failed.
So just catch the exception(s) and deal with the problem there.

Clustered Remote Object Bound To JNDI

Hello,
          I'd like to know if Weblogic 5.1 (service pack 10) supports
          clusterable remote objects.
          What I am trying to do is to implement a remote object that extends
          UnicastRemoteObject interface and bind it to JNDI. When the client
          needs the services, it will lookup that object in JNDI and call its
          methods remotely.
          What happens to my test implementation is that it all works well when
          I run Weblogic locally, but if it is run on the remote server, it
          gives me the exception to the extend that the stub for my remote
          object is not found (although it is in the classpath). I understand
          that this is because I should be using weblogic.rmic instead of
          regular rmic, is that right?
          Thanks,
          Eugene Kononov.

Creating remote objects and passing the retrieved data to modules

I found at this Adobe tutorial a nice "RemoteService" class that creates a RemoteObject and contains the functions for handling the result and fault events. If I wanted to use this approach, how could I pass the data from the result handler to interfaces that modules from the main application could use?
I could put the RemoteService/RemoteObject in the modules, but (in my opinion- and I could be wrong) the best design seems to be using the remote calls in the main app and passing the data along to the modules.
Ultimately, I would like to know what the "best practices" are for creating remote objects and passing the retrieved data to modules
Thanks!

Weblogic 10.3.0 issues with remote object calls.

All:
I was wondering if anyone has experienced any issues with Weblogic 10.3.0 dropping initial remote object calls over AMF Secure Channel. Here are the issues we are experiencing.
1. FLEX applications fail consistently on the first remote object call made across the AMF Secure Channel. Resulting in the request not returning from the application server; which has had varying affects on the different applications including missing data, application freeze and general degrading of the user experience.
2. FLEX applications require a browser/application refresh once the application has been inactive for a certain period of time. In our experiences the behavior occurs after 30 minutes of inactivity.
I've deployed this same code to Weblogic 10.3.3 and the behaviors go away. Are there any patches to 10.3.0 that might take care of this issue that we are not aware of?
Thanks for you help,
Mike

Breaking up data in a remote object

Currently I have a chart that gets its data using a remote
object connection. The chart currently shows a months worth of
data. Now I need to break that monthly data into weekly data. The
customer would rather have the data spread acroos four weekly
charts instead of just one monthly chart. The customer would then
just click click a 'Next' or 'Previous' button to cycle through the
charts.
I know that I just change the function (CFC) that calls for
the data to only return a weeks worth of data, but I don't want to
make a separate data call every time the user clicks 'Next' or
'Previous'
Is there a way to grab the whole month's data set and then
divide it into weekly data sets within the app?

Okay I figured this one out. If I add a hSlider with two
thumbs I can set the thumbs with just a couple of functions.
Basically when the user clicks either button a function is called
that passes in a predetermined value of how many tick marks to
move.
The HSlider has a property called 'values' that holds the
positions of all the thumbs. Using some simple functions they can
easily be manipulated.
Setting the slider's visible property to 'false' will keep
the navigation focused on just the buttons.

File upload through BlazeDS remote object?

Hi,
After researching file upload options in flex, it seems like the only option is through HTTP service requests, such as:
private var fileRef:FileReference;
fileRef.upload(new URLRequest(FILE_UPLOAD_URL));
Is there any way to use BlazeDS remote objects to upload a file from Flex interface? Perhaps passing in a FileReference object and marshalling it into an equivalent Java object?
Thanks!

I know there is a workaround like this. It uses a servlet to upload a file and returns a url. The uploaded file is either stored in session or server file system until the session expires. Use the PropertyProxy to register a custom class which contains this url and convert to java.io.File. It is the limitation of the player. It cannot read the local file system for security reason. There is a sample in blazeds/trunk/qa/apps/qa-regress/WEB-INF/src/blazeds/qa/remotingService/Echo.java
static
PropertyProxyRegistry registry = PropertyProxyRegistry.getRegistry();
PropertyProxy proxy = registry.getProxy(java.io.File.class);
if (proxy == null)
registry.register(java.io.File.class, new FileProxy());
proxy = registry.getProxy(FileReference.class);
if (proxy == null)
registry.register(FileReference.class, new FileReferenceProxy());
Hope it can help

DBMS_SQL.PARSE to access remote objects

I am using following code in a procedure ...
DBMS_SQL.PARSE (cur, vSQL, DBMS_SQL.NATIVE);
where variable vSQL can contain a remote object.
A DB link (with Fixed User option) exists to access that database.
The DB link is working. The remote object is accessible outside this procedure.
When this command is executed, I get ...
ORA-24374: define not done before fetch or execute and fetch
... error.
Can DBMS_SQL handle remote objects?
Oracle version is 9.2.0.5.0
Any help would be greatly appreciated.

Here is the code I am running ...
CREATE OR REPLACE PROCEDURE p_sql_valid_or_not_cnt
(vSQL IN VARCHAR2, vValid OUT NUMBER, vMessage OUT VARCHAR2, vCount OUT NUMBER) IS
-- Purpose: Returns 0 in vvalid if SQL is valid, else returns -1. Returns row count when SQL is valid.
-- Parameters:
-- IN : vSQL
-- OUT : vValid
-- OUT : vMessage
-- OUT : vCount
cur INTEGER := DBMS_SQL.OPEN_CURSOR;
fdbk INTEGER;
BEGIN
DBMS_SQL.PARSE (cur, vSQL, DBMS_SQL.NATIVE);
fdbk := DBMS_SQL.EXECUTE (cur);
vCount := 0;
LOOP /* Fetch next row. Exit when done. */
EXIT WHEN DBMS_SQL.FETCH_ROWS (cur) = 0;
vCount := vCount + 1;
END LOOP;
vValid := 0;
vMessage := 'No errors';
DBMS_SQL.CLOSE_CURSOR (cur);
END p_sql_valid_or_not_cnt;
To run ...
set serveroutput on
declare
i number;
m varchar2(500);
c number;
begin
p_sql_valid_or_not_cnt('SELECT * FROM TAB where 1 <> 1',i,m,c);
DBMS_OUTPUT.PUT_LINE(i);
DBMS_OUTPUT.PUT_LINE(m);
DBMS_OUTPUT.PUT_LINE(c);
end;
This runs fine.
But when I try to access an object from a remote server using DB link. I get the error ...
set serveroutput on
declare
i number;
m varchar2(500);
c number;
begin
p_sql_valid_or_not_cnt('SELECT * FROM REMOTE_SCHEMA.T_REMOTE@REMOTE_SERVER where 1 <> 1',i,m,c);
DBMS_OUTPUT.PUT_LINE(i);
DBMS_OUTPUT.PUT_LINE(m);
DBMS_OUTPUT.PUT_LINE(c);
end;
declare
ERROR at line 1:
ORA-24374: define not done before fetch or execute and fetch
ORA-06512: at "SYS.DBMS_SYS_SQL", line 1125
ORA-06512: at "SYS.DBMS_SQL", line 328
ORA-06512: at "IMEPAS.P_SQL_VALID_OR_NOT_CNT", line 16
ORA-06512: at line 6
I can run the SQL that I am passing as vSQL directly in SQLPLUS ...
This code in itself works.
SELECT * FROM
REMOTE_SCHEMA.T_REMOTE@REMOTE_SERVER
where 1 <> 1;
The user I am using to logon to my server is also there on REMOTE_SERVER.
The DB LINK is created by CONNECTED USER option. The user on REMOTE_SERVER has explict select access on the table (not via role) I am accessing.
Any help would be much appreciated.
