Calling PL SQL Procedure in Application Module Method

Hi Experts,
I want to know how can i call a plsql procedure in Application Module and get the value of the OUT parameter of procedure . if possible please provide some example
Thanks in advance.

Have a look at this sample code from one of our projects:
    CallableStatement cstmt = this.getDBTransaction().createCallableStatement(
      "{ call Expand_Message( ?, ?, ? )}", DBTransaction.DEFAULT);
    try
      cstmt.setString(1, arg1 );
      cstmt.setString(2, arg2 );
      cstmt.registerOutParameter(3, Types.VARCHAR);
      cstmt.execute();
      result = cstmt.getString(3);
    catch (SQLException e) {
      // Process eventual SQL exception here
    finally {
      try {
        cstmt.close(); }
      catch (Exception e) {;}
    }This code is part of a method in a custom ApplicationModuleImpl class (defined for one of the ApplicationModules) and the 3rd parameter of the Expand_Message procedure is an OUT-parameter.

Best practice for calling application module methods and plsql code

In my application I am experiencing problems with connection pooling, I seem to be using a lot of connections in my application when only a few users are using the system. As part of our application we need to call database procedures for business logic.
Our backing beans, call methods on the application module which in turn call a database procedure. For instance in the backing bean we have code like this to call the application module method.
// Calling Module to generate new examination/test.
CIGAppModuleImpl appMod = (CIGAppModuleImpl)Configuration.createRootApplicationModule("ky.gov.exam.model.CIGAppModule", "CIGAppModuleLocal");
String testId = appMod.createTest( userId, examId, centerId).toString();
AdfFacesContext.getCurrentInstance().getPageFlowScope().put("tid",testId);
// Close the call
System.out.println("Calling releaseRootApplicationModule remove");
Configuration.releaseRootApplicationModule(appMod, true);
System.out.println("Completed releaseRootApplicationModule remove");
return returnResult;
In the application module method we have the following code.
System.out.println("CIGAppModuleImpl: Call the database and use the value from the iterator");
CallableStatement cs = null;
try{
cs = getDBTransaction().createCallableStatement("begin ? := macilap.user_admin.new_test_init(?,?,?); end;", 0);
cs.registerOutParameter(1, Types.NUMERIC);
cs.setString(2, p_userId);
cs.setString(3, p_examId);
cs.setString(4, p_centerId);
cs.executeUpdate();
returnResult=cs.getInt(1);
System.out.println("CIGAppModuleImpl.createTest: Return Result is " + returnResult);
}catch (SQLException se){
throw new JboException(se);
finally {
if (cs != null) {
try {
cs.close();
catch (SQLException s) {
throw new JboException(s);
I have read in one of Steve Muench presentations (Oracle Fusion Applications Team' Best Practises) that calling the createRootApplicationModule method is a bad idea, and to call the method via the binding interface.
I am assuming calling the createRootApplicationModule uses much more resources and database connections that calling the method through the binding interface such as
BindingContainer bindings = getBindings();
OperationBinding ob = bindings.getOperationBinding("customMethod");
Object result = ob.execute()
Is this the case? Also is using getDBTransaction().createCallableStatement the best way of calling database procedures. Would it be better to expose plsql packages as webservices and then call them from the applicationModule. Is this more efficient?
Regards
Orlando

Thanks Shay, this is now working.
I successfully got the binding to the application method in the pagedef.
I used the following code in my backing bean.
package view.backing;
import oracle.binding.BindingContainer;
import oracle.binding.OperationBinding;
public class Testdatabase {
private DCBindingContainer bindingContainer;
public void setBindingContainer (DCBindingContainer bc) {this.bindingContainer = bc;}
public DCBindingContainer getBindingContainer() {return bindingContainer;}
public static String validateUser()
// Calling Module to validate user and return user role details.
System.out.println("Getting Binding Container from Home Backing Bean");
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
System.out.println("Obtain binding");
OperationBinding operationBinding = bindings.getOperationBinding("calldatabase");
System.out.println("Set username parameter");
operationBinding.getParamsMap().put("p_userId",userId);
System.out.println("Set password parameter");
operationBinding.getParamsMap().put("p_testId",examId);
Object result = operationBinding.execute();
System.out.println("Obtain result");
String userRole = result.toString();
System.out.println("Result is "+userRole);
}

How do I call an Application Module method from a EntityImpl class?

Guys and Gals,
Using Studio Edition Version 11.1.1.3.0.
I've got a price update form, that when submitted, takes the part numbers and prices in the form and updates the corresponding Parts' price in the Parts table. Anytime this Parts view object's ReplacementPrice attribute is changed, an application module method needs to be called which updates a whole slew of related view objects. I know you can modify view objects via associations (How do I call an Application Module method from a ViewObjectImpl class? but that's not what I'm trying to do. These AppModuleImpl methods are the hub for all price updates, as many different operations may affect related pricing (base price lists, price buckets, etc) and hence, call the updatePartPricing(key) method.
For some reason, the below code does not call / run / activate the application module's method. The AppModuleDataControl exists and recordPartHistory(key) is registered and public. At runtime, the am.<method> code is simply ignored, and as a weird side-effect, I cannot navigate out of my current page flow.
public void setReplacementPrice(Number value)
    setAttributeInternal(REPLACEMENTPRICE, value);
    AppModuleImpl am = (AppModuleImpl)this.getDBTransaction().findApplicationModule("AppModuleDataControl");
    Key key = new Key(new Object[]
        { getPartNumber() });
    am.recordPartHistory(key); // AppModuleImpl method which records pricing history
    am.updatePartPricing(key); // AppModuleImpl method which updates a whole slew of related pricing tables
}Any ideas?

Thanks Timo.
Turns out the code provided was correct, but the AppModuleImpl method being called was not. A dependent ViewObject wasn't returning the row I was expecting. I then tried to perform some operations on that row, which in turn ... just stopped everything, but didn't give me an error.
It was the lack of the error that threw me off. I had never messed with calling an AppModuleImpl method from the EntityImpl so I assumed that's what was messing up.
You are correct. It is available from the ViewRow, but I thought it better to put it in the EntityImpl. This method will be called every time the replacement cost is modified. If I didn't put it in the EntityImpl, I'd have to remember to call it every time a replacement cost changed.

Calling PL/SQL Procedures from Java

Hello,
I want to know, if it is possible to call PL/SQL Procedures from
SQLJ(which uses htp.print from the Package web toolkit ).
Though, it is possible to call normal procedures but if I want
to call PL/SQL procedures with htp.print then I get I error.
For example:
#sql{Call html_test()};
Can you give me a advice?
Your help is much appreciated!
M|ller

Oracle's htp packages are develop to be work with
mod_plsql/OAS/OWS webserver.
If you are trying to use htp packages first need to instanciate
some enviroment vars for htp packages, for example first you has
to call to owa.initialize procedure, populate owa.cgi array and
so on.
If you need more information about how this toolkit works you
could get the source of DB Prism at
http://www.plenix.com/dbprism/ this open source framework
includes backward compatibility with mod_plsql application and
then includes settings of this values from Java code.
Best regards, Marcelo.

How to invoke Application Module method from entity object methods

Hi,
We have an existing Application Module which provides some validation logic. We are using OperatingBinding or getting the Application Module instance from the bindings and then invoking the app module methods in the view controller project.
But in our current scenario, We need to invoke the application module method from the setAttribute method in the entity object when ever an entity attribute value is changed . I believe we can call createRootApplicationModule method to create application module instance. But this may lead to performance overhead.
Can you please suggest, if there is any alternative to invoke the application module method inside the business components.
What is the best way to create

We have a pricing service, which was developed as a separate application. We need to invoke the pricing service with the change in certain attributes of the entity object and update some of the attributes of the current entity object. At present we are handling these calls to the pricing service in the ui layer in the valueChangeListener.
But we would like to move this service call into setAttribute method as we are unable to prevent the call to the service if the model validations fail. I am looking for the best possible approach for invoking the service calls from the entity objects.
Thanks and Regards,
S R Prasad

Calling PL/SQL procedures from a Windows CMD script

Hello,
I am writing a Windows CMD script. From this script I want to call procedures from a PL/SQL package which selects, inserts or deletes rows from the database.
How do I go about logging into the database from the cmd script and calling PL/SQL procedures from there?
Does anyone have any examples of such scripts? Thanks in advance.

No, it is not a job that needs to be scheduled.
The script will be used when needed to select info from a certain table and also to insert or delete certain info into/from this table (so, it is just simple sql statements which I have put into a package), but I'm sure how to log into the database and execute the procedures from this package in a cmd script.

Thanks, it works.
In the “Assign Variables”
Changed from:
<copy>
<from variable="Invoke_1_ASNDBTest103_OutputVariable"

<to variable="outputVariable" part="payload"

So far so good, but one question, compiler gives warning…but everything works well.
Warning(97):

[Potential fix]: Please make sure that the return value of from-spec query is compatible with the to-spec query.
Also, instead of direct variable to variable copy, used expression to variable copy and it works. You can avoid the warning from the compiler.
Does not work ==> bpws:getVariableData('Invoke_1_ASNDBTest103_OutputVariable','payload','/ns3:OutputParameters/ns3:OUT_STATUS_CODE')
Works ==> bpws:getVariableData('Invoke_1_ASNDBTest103_OutputVariable','payload','/ns3:OutputParameters’)
So, why the compiler warning?

Got Call pl/sql procedure in C#

Hi Experts,
I tried to call a pl/sql procedure TEST_COMP from a .NET app in C# and got the following error, but the same code worked in VB, any advice?
Thanks,
James
ORA-06550: line 1, column 7:
PLS-00201: identifier 'UTIL_PKG.TEST_COMP' must be declared
ORA-06550: line 1, column 7:
UTIL_PKG is the name of package, I logged in as the owner of the package.
Here is the C# code, that gets an error:
string cmdString = "UTIL_PKG.TEST_COMP";
OracleCommand cmd = new OracleCommand(cmdString,con);
cmd.CommandType = CommandType.StoredProcedure;
try
cmd.ExecuteNonQuery();
catch (Exception ex)
Console.WriteLine(ex.Message);
Here is the VB code that works:
Dim cmdString As String = "UTIL_PKG.TEST_COMP"
Dim cmd As OracleCommand = New OracleCommand(cmdString)
cmd.Connection = con
cmd.CommandType = CommandType.StoredProcedure
Try
cmd.ExecuteNonQuery()
Catch ex As Exception
Console.WriteLine(ex.Message)

Double post:
Re: Got PLS-00201 error when call ps/sql procedure from .NET app in C#
The bottom line is it should work in both. So either you aren't telling us all the details, or something has changed and you don't even know it.

Calling Oracle BugDB PL/SQL Package Procedures from Application Modules

Hi Experts,
I am using JDev 11g R2.My requirement is as follows:
1.Create a public database link to remote bugDB using the Testing Environment.(Done)
2.Access the data from local database to BugDB using that DB link (Done)
3.Insert/Create a bug using the Create_Bug procedure in the API provided by BugDB(Failed).In the Application ModuleImpl class I have added the following code(Just an Example) to call the API containing a pl/sql procedure which creates a bug in the remote db table.
public void Create_Bug(String Product, String Component, String Subcomponent, String Status) {
CallableStatement st = null ;
try {
StringBuffer str = new StringBuffer();
str.append(" BEGIN ");
str.append(" Bug.Bug_API_V1.Create_Bug@bugtest( ");
str.append(" Product => :1, ");
str.append(" Component => :2, ");
str.append(" BugNo => :3 ");
str.append(" Status => :4 ");
str.append(" ")
str.append(" ); ");
str.append(" END; ");
st =getDBTransaction().createCallableStatement(str.toString(), 1);
st.setString(1, Product);
st.setString(2, Component);
st.setString(3, Subcomponent);
st.setString(4, Status);
st.execute();
} catch (SQLException sqle) {
// TODO: Add catch code
sqle.printStackTrace();
} catch (NumberFormatException nfe) {
// TODO: Add catch code
nfe.printStackTrace();
4.Added a managed bean to invoke this AppModuleDataControl which stores the value in the remote database.(Failed in this part).
Its not showing any errors in the log but the bug is not created either in the remote database.Could anyone guide me where am I going wrong or what is the better way to handle this requirement.Any suggestion for materials,links or tutorials would be highly appreciated.Thanks in advance.
Regards,
Prasanna

Prasanna,
this is a public form_ and the Oracle bug database API is not public! Can you please post internal questions to Oracle internal forums and mailing lists?
thank you

Calling PL/SQL procedure that returns boolean in java

Hi All,
Was not sure weather to post this on Java forum threads or PL/SQL forum threads. So posting at both locations.
I have to call a PL/SQL procedure from java. This PL/SQL has IN/OUT parameters as well as return a Boolean value.
The procedure definition is as follows:
FUNCTION GET_NEXT(O_error_message IN OUT VARCHAR2,
IO_item_no IN OUT ITEM_MASTER.ITEM%TYPE,
I_item_type IN ITEM_MASTER.ITEM_NUMBER_TYPE%TYPE)
return BOOLEAN;
END ITEM_NUMBER_TYPE_SQL;
And the java function I am using is as follows:
This is in the ADF Application module impl code
public String callNextItem(){
CallableStatement callableStmt = null;
String rmsUser = getDBTransaction().getConnectionMetadata().getUserName();
String callableStatement = "begin ? := ITEM_NUMBER_TYPE_SQL.VALIDATE_FORMAT(?,?,?); end;";
System.out.println("callableStatement "+callableStatement);
try{
callableStmt = getDBTransaction().createCallableStatement(callableStatement,0);
callableStmt.registerOutParameter(1, Types.*BIT*);
callableStmt.registerOutParameter(2, Types.VARCHAR);
callableStmt.registerOutParameter(3, Types.VARCHAR);
callableStmt.registerOutParameter(4, Types.VARCHAR);
callableStmt.setBoolean(1, false);
callableStmt.setString(2, "");
callableStmt.setString(3, "");
callableStmt.setString(4, "UPC-A");
callableStmt.executeUpdate();
System.out.println("STATUS : " + callableStmt.getString(3));
System.out.println("ERROR : " + callableStmt.getString(2));
String status = "";
getDBTransaction().commit();
System.out.println("commited ");
callableStmt.close();
return status;
}catch(SQLException e){
System.out.println("Error:" +e);
throw new JboException(e);
But this function never works. Throws "not valid expression type" error.
I have called several PL/SQL procedures before, only difference being
they never used to return any value. Particularly I feel the cause of the
error is the Boolean type that is returned from the procedure.
If you have any idea, please help.
