How to call a AM method with parameters from Managed Bean?

Hi Everyone,
I have a situation where I need to call AM method (setDefaultSubInv) from Managed bean, under Value change Listner method. Here is what I am doing, I have added AM method on to the page bindings, then in bean calling this
Class[] paramTypes = { };
Object[] params = { } ;
invokeEL("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
This works and able to call this method if there are no parameters. Say I have to pass a parameter to AM method setDefaultSubInv(String a), i tried calling this from the bean but throws an error
String aVal = "test";
Class[] paramTypes = {String.class };
Object[] params = {aVal } ;
invokeEL("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
I am not sure this is the right way to call the method with parameters. Can anyone tell how to call a AM method with parameters from Manage bean
Thanks,
San.

Simply do the following
1- Make your Method in Client Interface.
2- Add it to Page Def.
3- Customize your Script Like the below one to Achieve your goal.
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("GetUserRoles");
operationBinding.getParamsMap().put("username", "oracle");
operationBinding.getParamsMap().put("role", "F1211");
operationBinding.getParamsMap().put("Connection", "JDBC");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
return null;
i hope it help you
thanks

ADF how can i execute a query with parameters when the page renders

hi
i am using ADF web 11g
i need to execute a query with parameters when the page renders
thanks

hello,
I'm a fan of Java code, I really am.
But when you use ADF, you decided to move to a more declarative environment.
So why not do it declarative, the adf way?
In your pagedef insert a action binding.
This can be anything, a call to the application module, a call on the iterator(Like executeWithparams, etc.)
Create an invokeAction in your pagedef and set the condition.
This example refreshes(Action 2 is execute query) the data.
First the method binding:
    <action IterBinding="PersoonIterator" id="Execute" InstanceName="LSAppModuleDataControl.Persoon"
            DataControl="LSAppModuleDataControl" RequiresUpdateModel="true" Action="2"/>And the invoke action
    <invokeAction Binds="Execute" id="refreshData"/>This always refreshes the data on page entry, but anything is possible, you can set condictions for the invokeAction.
-Anton
PS Yes I know that pagedefs become backing beans in the end and yes that is Java code, but if you wanna play the ADF way, the goal is the reduction of Java code and the increased performance of declarative programming.

Passing a form bean with a link

Hii Javaties
I am passing some parameters from a jsp page to the action class in the following manner
�2=<bean write name="formbean" property="prop2" />Link
Can anyone tell me is this the right approach to pass paramters from a link .
Can i pass the whole form bean with a link ?

From what I understand you are using Struts, and as much as I know you have to configure struts so that when you click for example on a link with the url set as hello.do, it will actually get the hello form bean and handle it. However as much as I know you have to do this from the xml configuration!
I am not expert in struts however, but that is my feeling.

Is it possible in jsf? Action with parameters????

I have a NavigationItem, a object of myfaces.....
And when is clicked it, I want to create a new pane, based on the navigationItem clicked, obviuosly,
How I can submit a action with parameters???
Is it possible?
thanks all !

I will try to explain better.
I create menus dynammicaly....
and this menus has NavigationMenuItems, all componentes of myFaces
The navigationMenuItem is inherited of SelectItem.....
and creating it dynamically I need to put a action, and the backing bean has a method that return a string , but the value returned is always null, and I will to know How things I will do depending the parameters (like request parameteres) are passed through the action...
but I do not know how to set the action dynamically, when the method setAction expect a string and not a MethodBinding.....
And how I will to know after, what navigationMenuItem was clicked ??
I don't know if are answers to this questions, I'm not sure about the limitations of web development and jsf, but I must to do it...
thanks

Best practice for calling an AM method with parameters

Which will be the best way to call an AM method with parameters from a backing bean.
I usually use the BindingContainer to get the operation binding and then call execute function. But when the method have parameters, how to do it?
Thanks

Hi,
same:
operationBinding.getParamMap().put("argument1Name", argument1Value);
operationBinding.getParamMap().put("argument2Name", argument2Value);
operationBinding.execute();

SessionSynchronization methods in Stateless Bean with BMP

Hi,
Why cant we use SessionSynchronization methods in Stateless Bean with BMP?
Just cos the bean has full control over the transactions and it doesnt make sense at all or there is something more to add to this.
Thanks in advance,
Seetesh

Hi,
Why cant we use SessionSynchronization methods in
Stateless Bean with BMP?Stateless Session Bean does not miantain the state across the method call.And the Transaction control is lying within the method call.
Just cos the bean has full control over the
transactions and it doesnt make sense at all or there
is something more to add to this.I dont understand what you are trying to say here.As stateful session bean maintains the state across the method calls and maintains the conversational state which lies is as cache.The Transaction can be aborted either by making the changes to old value and throwing the Exception to client indicating regarding the failure.But this will be great lost of work hence you make(find mechanism) a recovery from the old values which should be saved.
It is for this the specification has come up with SessionSynchronization interface (useful for only Stateful) Session Bean and with (declarative Transaction) CMT.

Error While Deploying A CMP Entity Bean With A Composite Primary Key

Hello all,
I have a problem deploying CMP Entity beans with composite primary keys. I have a CMP Entity Bean, which contains a composite primary key composed of two local stubs. If you know more about this please respond to my post on the EJB forum (subject: CMP Bean Local Stub as a Field of a Primary Key Class).
In the mean time, can you please tell me what following error message means and how to resolve it? From what I understand it might be a problem with Sun ONE AS 7, but I would like to make sure it's not me doing something wrong.
[05/Jan/2005:12:49:03] WARNING ( 1896):      Validation error in bean CustomerSubscription: The type of non-static field customer of the key class
test.subscription.CustomerSubscriptionCMP_1530383317_JDOState$Oid must be primitive or must implement java.io.Serializable.
     Update the type of the key class field.
     Warning: All primary key columns in primary table CustomerSubscription of the bean corresponding to the generated class test.subscription.CustomerSubscriptionCMP_1530383317_JDOState must be mapped to key fields.
     Map the following primary key columns to key fields: CustomerSubscription.CustomerEmail,CustomerSubscription.SubscriptionType. If you already have fields mapped to these columns, verify that they are key fields.Is it enough that a primary key class be serializable or all fields have to implement Serializable or be a primitive?
Please let me know if you need more information to answer my question.
Thanks.
Nikola

Hi Nikola,
There are several problems with your CMP bean.
1. Fields of a Primary Key Class must be a subset of CMP fields, so yes, they must be either a primitive or a Serializable type.
2. Sun Application Server does not support Primary Key fields of an arbitrary Serializable type (i.e. those that will be stored
as BLOB in the database), but only primitives, Java wrappers, String, and Date/Time types.
Do you try to use stubs instead of relationships or for some other reason?
If it's the former - look at the CMR fields.
If it's the latter, I suggest to store these fields as regular CMP fields and use some other value as the PK. If you prefer that
the CMP container generates the PK values, use the Unknown
PrimaryKey feature.

Calling stored procedures with parameters with the Database Connectivity Toolkit

Hi all,
I am new to the forum and am having difficulty finding a solution to a particular problem I am having regarding using the LabVIEW Database Connectivity Toolkit on a project I am currently working on at my job. I have a database in which I have tables and stored procedures with parameters. Some of these stored procedures have input, output, and return parameters.
I have been trying to follow this example but to no avail: http://digital.ni.com/public.nsf/allkb/07FD130746083E0686257300006326C4?OpenDocument
One such stored procedure I am working on implementing is named "dbo.getAllowablePNs", which executes "SELECT * from DeviceType" (DeviceType is the table). In this case, it does not require an input parameter, it has an output parameter that generates the table [cluster], and has a return parameter which returns an integer value (execution status code) to show if an error occurred. The DeviceType table has 3 columns; ID (PK, int, not null), PN (nvarchar(15), null), and NumMACAddresses (int, null). I have gone over many examples and have talking to NI support to try to implement this and similar stored procedures in LabVIEW but have not been successful. I am able to connect to the database with the Open Connection VI without error, but am running into some confusion following this step. I am then trying to use the Create Parameterized Query VI to call the stored procedure and set the parameters. I assume I would then use the Set Parameter Value VI for each parameter that is wired into the parameters input on the previous Parameterized Query VI? I am also having some confusion during and following these steps as well. I would greatly appreciate any advice or suggestions anyone might have in regards to this situation as I am not a SQL expert. Also, I would be happy to provide any more information that would be helpful.
Regards,
Jon
Solved!
Go to Solution.

Also, I don't know if this would be helpful but here is the actual stored procedure in SQL:
CREATEPROCEDURE [dbo].[getLastSequenceNumber]
@p1 nvarchar(10)='WO-00000'
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SETNOCOUNTON;
-- Insert statements for procedure here
selectmax(SequenceNumber)from Devices where WorkOrderNumber= @p1
END

Discoverer report with parameters and functions

I am new to Discoverer. Is there a way to create a report (with parameters) of one line per customer such that the following data will be displayed for each customer?
Among the parameters is: from_date (month & year) ,to_date
The basic query gives totals for each date (month & year) for every customer.
Among the fields displayed:
1-customer_id,
2-balance until from_date,
3-total activity between from_date and to_date
I have a function to calculate the total balance until from_date, but then I cannot get the total activity on the same line. I tried using another function and I tried using a total calculation but to no success.
Is this possible?
Thanks.

Hi Markus
You need to determine whether you can in fact call a Discoverer report using a URL before linking it in Portal. You need to run the report in Viewer first and then see copy the URL from the address line of the browser. Then you open another browser and paste the URL. You may well be prompted for a username and password but hopefully the correct report with the right parameters will then execute.
Assuming this works you then paste the same URL link into Portal and you should be able to get the report to run.
Best wishes
Michael

I cann't execute javac with parameters. please help !!

Hi All!!
I can't understand how to execute application or bat file (javac.exe for example) WITH parameters correctly.
I can execute javac.exe or bat file - WITHOUT parameters :
Process p = Runtime.getRuntime().exec(WIN_PATH + " " + WIN_FLAG + " " + "javac.exe");
But I can't execute correctly the command like:
"javac.exe -classpath C:\Alex; Test.java"
I tried to use exec(str,env[]) and exec(cmd[]) methods, but there were different errors as a result :(((
How can I execute the command "javac.exe -classpath C:\Alex; Test.java" ? Is it possible?
Please help me by a good idea.
Thank you.

right you are! That's why we use "\\" instead "\" :)
If i try to execute this command -
cmd=WIN_PATH + " " + WIN_FLAG + " " + "c:/j2sdk1.4.0/deleteMe/javac.exe -classpath C:/WORK/jboss-3.0.3/client/jboss-j2ee.jar;S:/Alexander/jars/sys.jar;S:/Alexander/jars/ejb_conf_dev.jar;S:/Alexander/jars/; C:/j2sdk1.4.0/deleteMe/aaBean.java";
my OS Windows 2000 returns na error - "Error opening icon..."
What's wrong?
Thank you...

Multiple users accessing entity bean with same PK

Hi,
Some body please clarify the below issue.
(EJB 1.1, WAS3.5)
I have two app servers and two clones each clone is running in each app server.
Stateful session bean access Entity beans to update/read record in the database.
According to my requirement multiple users can access the same entity data (same primary key). Suppose user A created a Stateful session bean SB1 and the SB1 created Entity1 with PK1, this is happening at clone1.
User B accessed the site and the request went to Clone2 and a new SB2 created, but the SB2 need to access the database with Same PK1.
For the above situation, I guess container can not create a new Entity bean with PK1 because EB with PK1 is already there and it tries to allocate same EB1 with SB2, so if two requests are concurrent do the SB2 wait to get the handle of the EB1?
Is there any way to create two Entity beans with same Primary Key at the same time but in different clone?
Thanks,
Sagar

Hi,
The concurrency level has to be set at the level of database and the database will take care of consistency & integrity of the data. So specity the concurrency level on the database connection in each appserver.

List view - filter with parameters

Hi,
I need to define a list view to filter data with parameters.
I saw how to do it with the SPD in another post
http://social.msdn.microsoft.com/Forums/sharepoint/en-US/92271aa4-6582-4ea5-a10f-deaf02d2b62c/filtering-the-list-view-by-passing-date-parameters-using-sharepoint-desginer-2010?forum=sharepointcustomizationprevious
But need to do it in visual Studio (via definitins or Object Model).
How can I do that in Visual Studio?
Help is really appreciated.
Many thanks,
DD

Hi,
According to your description, you might want to create a list definition with the filter value from query string from URL. Then when you create a list instance with this list
definition, you will be able to filter the list view page by appending parameters to the URL in the address bar.
You can achieve this through modifying the Schema.xml file in the list definition project in Visual Studio like this:
How to create custom list definition

CAML Query Schema
http://msdn.microsoft.com/en-us/library/office/ms467521(v=office.15).aspx
Then we can filter the list with such an URL:
http://sp/Lists/List1/AllItems.aspx?Param1=2014-08-24&Param2=2014-08-28
