PLSQL Entity or Java Entity

I have requirement like this.
I have to update the table underlying my page and also should insert in Interface table.
Which will be best.PLSQL Entity or Java EO.

Have a Java EO to insert data into your table..
Before commit insert data into the intereface table by calling a pl/sql procedure..

Calling plsql block in java

Hi
Needs some help, urgently.
i have to call/execute a plsql block in java program.
block is similar to this
declare
CURSOR l_csr IS
select empname, empid, empdate from emp
order by empid;
l_empid NUMBER;
l_empdate DATE;
l_empname varchar2(30);
o_dateProfileId NUMBER;
o_dayofweekprofileid NUMBER;
begin
open l_csr;
loop
FETCH l_csr INTO l_empid , l_empname , l_empdate;
EXIT WHEN l_csr%NOTFOUND;
DETERMINEEMPPROFILE(l_empdate,o_dateProfileId,o_dayofweekprofileid,l_empid ,FALSE);
IF(o_dateProfileId IS NOT NULL) THEN
SELECT totaljobs INTO l_max1 FROM dateprofile WHERE dateprofileid = o_dateprofileid;
ELSE
SELECT totaljobs INTO l_max1 FROM dayofweekprofile WHERE dayofweekprofileid = o_dayofweekprofileid;
END IF;
END LOOP;
EXCEPTION
WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE('SQLCODE = ' || SQLCODE);
END;
i need to call this in java program and take the results of l_max1.
can someone provide an example of hot to do this or sample code
appreciate any help

I'm assuming this is for Oracle. Take a look at this article [url=http://www.enterprisedt.com/publications/oracle/result_set.html
]here for an example of how to use java to parse a result set from an Oracle procedure.

Howto map to an odata model function import returning an entity, not an entity set?

Hi,
how do I map to an odate model function import returning an entity (not an entity set) in a XML view? I tried property mapping {/method/property}, which does not make a network request and sets the value to null and I tried aggregation mapping {/method}, which makes a network request with $skip=0&$top=100&$inlinecount=allpages which is of course rejected by the odata source.
Thanks,
Wolfgang

Hello Dr. Wolfgang,
you can use
var oParams = {};
oParams.Field1 = 'ABC';
oParams.Field2= 'XYZ';
oParams.Field3= '123';
oModel.callFunction('MyFuncImport', 'GET', oParams, null, function(oResponse){
        alert("Call to Func Imp successful");
    },function(){
        alert("Call to Func Imp failed");});

Business Components for Java entity beans of J2EE

What is the future of Business Components for Java with the new standard entity beans of the sun Java 2 Entreprise Edition?
Thanks.
null

The Standard Entity Beans are a component (JavaBean) that can be a small piece of the ultimate application needs.
Oracle Business Component for Java is a complete framework that has numerous features that make developing COMPLETE applications easy.
Please download the white paper on Business Components, try your hand at creating an application with Business Components (using the wizards) and you will see that Business Components for Java is much more than a simple (/complex) reusable component, it is a complete framework which maked developing N-tier applications almost trivial by allowing you to focus on writing your business logic while the framework takes care of all the application infrastructure and the necessary plumbing.

Trying to set a calculated attribute in an entity implementation java file

Hi,, im working in Jdeveloper 9.0.3.2 in a web application and the problem is as follow:
I have one table, This table has an attribute which value is calculated from another attribute in the same table. Take in account That it is not a trascient column, it is a real entity column in the entity object.
First i tried this by using custom code in the validateEntity method but it was impossible because of the error: "JBO-28200: Validation threshold limit
reached. Invalid Entities still in cache".
next, i try the same by using custom code in the setter and getter methods by using the populateAttribute method and seems that transaction is successful but this result is only reflected in the entity cache so when im query directly the database this attribute is empty.
I have not idea what to do.. im bored trying to get solution to this problem.
Please help me!!!
Thank u

Thank you very much for the answer.
I tried to do what you suggested, but I get an error message when I tried to put session data into the user session object on my JSP page.
Here is part of my codes in the JSP page.
<%
// Retrieve all request parameters using our routine to handle multipart encoding type
RequestParameters params = HtmlServices.getRequestParameters(pageContext);
String dsParam = params.getParameter("datasource");
String formName = dsParam + "_form";
String rowAction = "Current";
String event = "Update";
String userName = (String) session.getAttribute("userName");
if (!(getDBTransaction().getSession().getUserData().containsKey("user")))
getDBTransaction().getSession().getUserData().put("user",userName);
%>
And here is my error message.
Error(16,16): method getDBTransaction not found in class _DecalDataEditComponent
I got the other half working where I retrieved the session data in a setter method of an Entity Object Class as below.
public void setDestroy(Date value)
if (value!=null)
setDestroyedBy((String)getDBTransaction().getSession().getUserData().get("user"));
setAttributeInternal(DESTROY, value);
Your help is very appreciated.

Accessing HttpSession in entity Impl.java

Can someone please tell me if it is possible (and if so how) to set a HttpSession variable from within the entity's Impl class ?
Currently I am overriding the doDML method to obtain the sequence number generated during the insert. I then want to use this later, hence need to store it somewhere
Thanks,
Brent

What I was getting at above was something like this:
protected void initializeBindingsForPage(DataActionContext ctx)
    // TODO: Override this view.fwkext.BaseDataForwardAction method
    // super.initializeModelForPage(ctx);
    HttpServletRequest request = ctx.getHttpServletRequest();
    String strRemoteUser = request.getRemoteUser();
    System.out.println("remoteUser=" + strRemoteUser );
    setBindingValue("CreatedByUsername"
       , strRemoteUser
       , ctx );
}In this case, the application was written to use FORM-based authentication, and the user then gets "stuffed" into an audit field exposed on the page's bindings. From there, you'd have it on the backend when the DML was eventually called.
Am I missing something?

Calling a PLSQL package from java

Hi All
I have a problem calling a package from java. I have to pass a Date to the package which is a String in java.
How can I typecast it to the PLSQL Date from a java String.
Here is my below code for reference. The below code does not works because of typecasting problem.I tried to_date() also in java, but it is not working.
cstmt=connDbConn.prepareCall("{call pkage.PACK1(?)}"); cstmt.setString(1,"01-JAN-2009");

keyanwb wrote:
How can I typecast it to the PLSQL Date from a java String.That datatype in Oracle contains a date and time component.
Thus you should consider exactly what storing the date only component means in terms of the timezone that the Oracle server is using.

Intersection/Associative Entity and Normal Entity in ERD

Hi,
Could anybody please tell me how I should differentiate between an intersection/associative entity (resulting from many-many relationship) and the normal entity in the E-R Diagrammer of Designer 6i???
Regards,
Moiz

What is your defintion of a normal entity.
Are you looking for a naming standard or modeling standard?
Are you attempting to transform a many-to-many? I think designer will generate the appropriate intersection but you may need to adjust the settings. Use surrogate keys and both for constraint implementation.

I have a table called cabin_table with id has not null.
Thanx in Advance

Thanks Buddy,
I think that was the correct one, but as i was using the example of ejb1.1 compatible, this is futher giving me a problem, Says U need to make the methods in the bean as abstract, i think this is as per the ejb2.0 specs right?.
I would try for that ad come back to u
Thanks
