I have a table in my model and I want it to have 4 integer primary keys
(defaulted to 0). When I create a new entry in this table using
DataServiceTransaction.createItem(), only the PK1 goes correctly, the
rest go as the default value 0. I tried to change the type of PKs to
string but to no avail. What may be going on?Please note the IDs are not
auto generated-RK
Hi AshishThere is nothing else in log other than the following. Where do
I find hibernate configuration file. There is none in my project folder
and the only place hibernate is being configured is in the .fml file
that also I pasted..: You should set
hibernate.transaction.manager_lookup_class if cache is enabled
thanksRupak
HelloI keep seeing the above error in my server log. My model file has
the following. What is the warning about and how to rectify it in the
right waythanksRupak java:comp/env/ALGODB org.hibernate.dialect.Oracle10gDialect

It is resolved now. Upon careful examination of the log, I found that
the MessageBrokerServlet was indeed throwing an exception due to a wrong
tag being used in messaging-config.xml file..
HelloI have seen lot of posts regarding this but no clear reason why
this would happen. My server runs under Tomcat 6.0.33. In a spearate
thread, I try to get MessageBroker msgBroker =
MessageBroker.getMessageBroker(null); but it always returns null. In my
web.xml, there is a valid servlet MessageBrokerServlet with
load-on-startup = 1. In one of the posts Rohit suggested copy jta.jar to
tomcat libs but it doesnot help either. I tried to wait 30 secs or so in
my thread before invoking MessageBrok...

Hello,I am following the steps mentioned in LCDS guide on setting up
Tomcat (6.0.33) login. The configuration file details are mentioned
below... Based on that, my observation is that the user "tomcat" and
"rupak" can login successfully. However the remotingService called
AdminControlService has security constraint of trustedAdmin and the user
rupak or tomcat dont have the roles of twsadmin but the login is
successful on amfChannel for these users while I expect it to fail
because of the securit...

I played around with the parameters.. It appears the arguments –
previousVersion and Changes have to be non null? If I provide valid

while it is working, I noticed that my additions to the database using
DataServiceTransaction.createItem() have stopped displaying on the
client GUI but are making it to the database. If I switch back to
ordersService.getAll() from the new method
ordersService.getSortedByTWSTimestamp(), then the client GUI is happily
updated.. any ideas...

HelloI am using the following code to push an entry to the client and
also create a new one in the database. However subsequently I want to
just update the previous entry with new volume and price. So I use the
updateItem() as shown below. Please note that the entry in the database
is already present, I am just updating it as part of this test..
DataServiceTransaction dtx = DataServiceTransaction.begin(false);
dtx.setSendChangesToAdapter(true); Positions p1 = new Positions();

My mistake… I was still calling ordersService.getAll() in the client
instead of ordersService.FillSortedByTWSTimestamp()..it should be okay
now.. The changes are made in the auto-gen AS file instead of java
file..
It did not help yet.. Here is the FML.. After making the change in model
file, If I click on Generate Code..do I expect to see any changes in the
auto-gen java code.. I don’t see any change though (like in the
assembler file)..
HelloI am using model driven development. I am using getAll in the Fill
method. But the results are not returned sorted by some field that I am
interested in. How do I tell the Fill to sort it by some field. Is there
some annotation that I can provided in the model...thanksRK
PamI like the PREPEND approach but not sure if it can be used with code
snippet I am using..If you are referring to registering an eventListener
on DataService as in :- then the alarmResultHandler() doesnot get called when the data is
pushed from the server using DataServiceTransaction. It gets called when
I launch the screen and it calls Fill() to populate the grid..pls advise
thanks
PamI think so but am still not there.. I am using the following code to
push the entry from the server. How do I specify PREPEND_TO_FILL.public
void doSomething() {DataServiceTransaction dtx =
DataServiceTransaction.begin(false);
dtx.setSendChangesToAdapter(true);Currency c1 = new
Currency();c1.setCurrencyCode("ABC");c1.setCurrencyName("Dummy
Currency");c1.setCurrencyLastUpdated(new
Date());dtx.createItem("currencyService", c1); <-- this results in the
exception belowdtx.commit();}thanksRupak
Ok, to cut the chase, all I want to do is to display on the top of the
grid the newly added items to the grid (basically keep the table sorted,
latest event always on the top). I am getting these items to be
displayed in real time by server side push. How do I achieve this..I am
using advancedDataGrid but I can use DataGrid Too if that helps…
ScottThanks for the response but which method from that file gets called
when a response is received from the server..I checked the file
SuperServicename.as and it has the Fill methods and the ones to
create/update an item etc.. ThanksRK
As a follow up on this thread, when the updates are sent to the client
(using the DataServiceTransaction.commit()), which function gets called
in the mxml file. I want to catch those events in the client and act on
them accordingly. Currently they are being silently written to grid on
my screen...
I'd like a mechanism where the LCDS detects any changes in the App
Server log file and sends them to the Flash client for display. Is there
a practical one...?thanksRK
HelloI have an LCDS server running under tomcat that works fine so far
and I can call remote procedures defined in remoting-config.xml. So far
all is well. Now in this server application, inside a servlet.init(), I
start a java thread that creates a java.net.ServerSocket and starts
listening to it for data that is coming from some other remote machine
over the TCP/IP socket.If I instantiate this java thread, I am unable to
call remote procedures from the flex client. I get an error - RPC Fault

Rohit,It doesnot look like from the log below that the write is
happening but the call seems to be going to the assembler/adapter, I
have specifically set the assembler to CurrencyAssembler on the entity
Currency on the model so that it uses the auto generated
CurrencyAssembler instead of default FiberAssembler. Is there anything
custom that needs to be done in the model generated
CurrencyAssembler.createItem() ?*** Log Messages below
