Bind a checbox to an Integer

Hi,
I have some data in my database that I would consider as boolean, but whose are SMALL INTEGER (Oracle doesn't provide the BOOLEAN type). In my JSP page, I associate checkbox to these datas, but I don't know how I can make the link between a checked box and the value 1 (and between a no checked box and the value 0).
I know that I can bind a property, but I have a lot of checkbox on my page and I can't write a getter method for each one!
Can I use a kinf of converter, or similar?
Thanks

Creator is not very robust when it comes to Boolean values. We use MySQL and Creator only seems to respect values which are typed as Tinyint(1) as Boolean. This is a problem as we integrate from legacy systems which use Char, Integer and other data types which use business rules (ie non-zero = true) to manage Boolean states.
The only way around this that we have found is to code it the hardway:
[1] create a getter/setter paid such as getMyBooleanVal()/setMyBooleanVal() in the backing bean which returns a boolean and use the getter to interpret the value from a row-set using the getValue() method and any appropriate business transformations..
[2] set the value property of the check box to the getter/setter
[3] perform for each checkbox!!!!
You could also write a customer converter which performs the same functions. This is much less tiresome if (a) there are many instances of check boxes which have to be dealt with, and (b) your transformation is standardized across your application.
Customer converters are simple to create and integrate but Creator seems to complain if you attempt to put them into the attributes in the JSF and they are not properly registered. We find the best way is to set the converter property for the requisite controls in the backing bean's initialization code eg
checkbox1.setConverter(new myCustomConverter());
which we would put in the page constructor.
I hope this helps you. I posted a customer converter for uppercasing text somewhere on the forum which you could probably find and modify for your needs.

64 bits integer handling

I can't find the way how to bind or define 64 bits integer using Oracle 8.1.7 OCI.
Plz, tell me any effective way to handle 64 bits integer.

<BLOCKQUOTE><font size="1" face="Verdana, Arial, Helvetica">quote:</font><HR>Originally posted by Shoaib ([email protected]):
If 64-bit is the normal size of integer on your platform, then passing using SQLT_INT for data type and sizeof(int) should work for your bind and define calls.<HR></BLOCKQUOTE>
Thank you for your comments.
The normal size of integer in my current platform is 4 bytes, 32 bits. The current 64-bit type is "long long" type. The OS I tested are Compaq Tru64 Unix V5.1 and Linux . For "long long" type, SQLT_INT and sizeof(long long) has failed.
As work around the 64-bits integer is fetched as string into SQLT_STR defined host variables. After that, conversion from string to integer is executed using atol().
Any other good working alternative?

Could not find selected item matching value "New" warning message in ADF

Hi,
I have a selectOneChoice1 for a field which has the following fixed values in it. And while creating it, I selected the 'SelctionRequired' option so that this field will always have a value.
New
Pending
Completed.
While navigating to this page, I am trying to set the value to 'New' (Retrieved from the DB) in the backing bean. But when the page is rendered, the above field is empty with the above options in the list and jdev has the follwing error message in its log.
WARNING: Could not find selected item matching value "New" in CoreSelectOneChoice[UIXEditableFacesBeanImpl, id=selectOneChoice1]
Can any one help me with this issue?
Thanks,
Priya

The value of a list binding is the zero-based integer position in the list that is selected, not the actual underlying value.
The simplest way to set the value of an attribute is to use an attribute binding (which can be bound to the same attribute as the list binding). When you set the value of an attribute binding, it sets the value as you supply it. Otherwise, you'd need to set the list binding's value to the numerical "slot" number of the one you want to change the value to.

Creating View Objects for complex query

Hi All,
I am trying to create a VO for inner query, but i am not able understand what type of bind variable to select.
PFB the scenario:
I have 2 tables, say orders, products
I am supposed to execute the following query:
Select * from Orders o, Products p where o.order_id = 123 and p.product_id in (111,222,333.....)
In the VO when I try to create, I need to create 2 bind variables
1 for order id and other for product id
the problem i am facing is selecting the type of the bind variable
I am selecting "Integer" type for order id bind variable but i am able to understand what should be the bind variable type for the product id.
I tried to use "Array" type, but in the query it is "= : bindvariable" operator instead of "in (: bindvariable)"
Also, please note that, the number of product_id is not fixed and is dynamic.
So my question is:
what should be bind variable type that should be used (for product_id case)?
Also, please advice if it is the same way to apply the criteria in AMImpl class.
Thanks in advance.
Thanks,
Varun

Varun,
this will not work as you can't use bind variables in sql IN queries.

JSF & converters

Hello, sorry for my bad english.
I don't understand something.
Use a outputText for example, and bind its value to an Integer for example, already instanciated in the backing bean.
Then, set a DateConverter to this outputText and display the page, you will see that your inputText displays a Date, that have probably been instancied by JSF.
I no really have problem with this, but when I look at the DateConverter code of the sun reference implementation, I don't see any new date instanciation. I even have the feeling that a ConverterException should be thrown.
So, I would know where is this date create, and why.
Do you know more about this?
If no, do you know if there is "log mode" that could help me see which methods are called?
Thanks in advance.

But here, the converter is used to display something from the backing bean, not to convert a string as an object.
So you say that, if the attribute is not of the correct type ( an Integer and not a Date), then the converter will first use getAsObject???
In the getAsObject method, a parser is used to parse "value", and if value is not a date, this should send a ConverterError in my advice. Or parser.parse(value) could eventually send a new Date if value is not an instance of Date...
I don't exactly know.
Thanks for answers.

ADF Mobile: WebService data control method call with array

I have also tried invoking this through a regular ADF application and that works fine with an int[]. It looks like something specific to the ADF Mobile SOAP layer.

No luck. A WS DC method call with a simple parameter (java.lang.String or java.lang.Integer) works fine but I can't get it to work when there is an array input.
I have tried WS methods with int arrays and simple string arrays without any luck. All of them result in a cannot serialize error.
I can't figure out what I am doing wrong. Are there any working WS Datacontrol samples with array inputs?

OCI And Threading

I have an OCI program running on NT. Things seem to run fine for
a while, however, if I have multiple clients or one client with
multiple threads, a situation occurs where although
client/thread 'A' has a row locked (via a select for update in a
stored procedure), client/thread 'B' can occassionally lock the
row!!! At first I thought it may be due to client/thread 'B'
caching information, so I tried completely
disconnecting/connecting to the database between calls... and
its still happening. What would cause a connection to release
it's locks, other than a commit/rollback?

All you need to do is out-bind a char buffer and integer status to a call to a PL/SQL statement that calls dbms_output.get_line(). When status == 0, there is a line in the buffer:
char buffer[32767];
int status = 0;
sb2 indp = OCI_IND_NULL;
char *sql = "BEGIN DBMS_OUTPUT.GET_LINE(line=>:p1, status=>:p2); END;";
OCIHandleAlloc(envhp, (dvoid **)&sth, (ub4)OCI_HTYPE_STMT, (size_t)0, (dvoid **)0);
OCIStmtPrepare2 (svc, &sth, errhp, sql, strlen(sql), 0, 0, OCI_NTV_SYNTAX, OCI_DEFAULT);
OCIBindByPos(sth, &bhp1, errhp, 1, (dvoid *)value, sizeof(value)+1, SQLT_STR, &indp, 0, 0, 0, 0, OCI_DEFAULT);
OCIBindByPos(sth, &bhp2, errhp, 2, (dvoid *)&status, sizeof(status), SQLT_INT, &indp, 0, 0, 0, 0, OCI_DEFAULT);
ret = OCIStmtExecute(svc, sth, errhp, (ub4)1, 0, NULL, NULL, OCI_DEFAULT);
while( OCI_SUCCESS==ret && 1 != status ) {

Button not submitting/ firing action code.

Hi All.
In Creator, I seem to be having problems with a specific page. It doesn't seem to matter how many buttons I try to drop on a page (with a number of databound controls on it), but the buttons just don't seem to fire off the backend code. according to the action property of the button, the backend code associated with that method should fire, but it just doesn't. I've tried just throwing a button on the page and putting something as simple as
log("the code in the button got fired");
return null;But even something so simple as that does not fire.
In any other page, that code works fine (obviously). I just hate the idea of having to re-develop the page from scratch when I encounter such an issue (especially after how much time it took given all the data bound controls). If anyone can point me to someone having a similar issue, or could give some feedback on this one It would help a great deal (even though this is quite ambiguous.)

you were 100% correct. I recieve the following message:
Validation Error: {0}Value is not valid
I recieve this on RadioLists that I have bound to a numerical column on an Oracle database. The String based bindings seem to work fine. Perhaps you can inform me of any mistakes I have made with the following when I expect the selection to bind to the numerical column:
Integer zero = new Integer(0);
Integer one = new Integer(1);
listYesNo = new java.util.ArrayList();
listYesNo.add(new SelectItem(one,"Yes",""));
listYesNo.add(new SelectItem(zero,"No",""));
// same error when using code as commented below too:
//        listYesNo = new java.util.ArrayList();
//        getListYesNo().add(new SelectItem("1","Yes",""));
//        getListYesNo().add(new SelectItem("0","No",""));

Multicast on linux

I can't understand why I can't receive multicast messages if I use MulticastSocket(SocketAddress addr) costructor instead of MulticastSocket(int port) costructor. This works fine in Windows while it doesn't works on Linux (Mandrake 9.1) or FreeBSD (5.0).
I will be able to bind my process to specified address and to join a group to receive multicast messages too.
Someone know the reason?

No, the Address is correct. This code runs perfectly under windows Me and runs also on Linux but only if the address is 0.0.0.0 or the multicast address (in this case 225.0.0.1)
Windows (and I think that is rigth) doesn't allow to assign multicast addresses (224.0.0.0-239.255.255.255) while Linux does.

How to bind SelectManyChoice to Integer array parameter

Hi.
I am using JDev TP4. I need to populate an integer array with the keys of the items selected in a SelectManyChoice.
I have created a page with a parameter form for the three parameters and a readonly table for the result class from a data control for this method:
public FreeGuaranteeModel[] getFreeGuarantees(Timestamp firstDate, Timestamp lastDate, Integer[] companyIds)
In the parameter form i have created a SelectManyChoice which displays a list
from a viewObject by dragging the companyIds parameter onto the parameter form, creating a SelectSingle component and then converted it to a SelectManyChoice.
The page renders ok, I can select one or more items in the list, but when I press the button to execute the method, the companyIds array is empty.
(The two date parameters are populated).
What am I missing? Is the binding wrong? I am new to JDev so if there is some other way to do this, please let me know.
This is the relevant part of the jspx:
<af:selectManyChoice value="#{bindings.companyIds.inputValue}"
          label="#{bindings.companyIds.label}"
          shortDesc="#{bindings.companyIds.hints.tooltip}"
          binding="#{backing_ViewFinancialResult.selectOneListbox1}"
          id="selectOneListbox1">
<f:selectItems value="#{bindings.companyIds.items}"
     binding="#{backing_ViewFinancialResult.selectItems1}"
     id="selectItems1"/>

Hi,
Thank you for your answer.
Following the example I was able to get the selected entries into an Integer array property with accessors which I created in a managed bean.
But I have not been able to get the values into the companyIds parameter of the method to execute.
Is there a way to bind directly to this parameter, or do I have to collect all parameters through separate properties and then call my method manually when the button is pressed?

I was trying to bind a integer value to a VO using setWhereClauseParam(1, myId); but it gave error while compiling.
Can anyone please tell me the reason why i got error?

1) OAF has it'S own forum!
2) which exception you got?

How do you bind a 64bit integer for input?

Is there any way to get oracle to deal with 64 bit integer bind values or must I bind
them as strings?
This is on intel linux.
Thanks,

SQLT_INT would be sufficent on a 64bit platform.

Slow performance when using cursor with bind variable

i'm facing the problem mentioned in the subject.
whenever i use the bind variable it would take more than 5mins to fetch 157 records, but if i hardcode the value ( not using variable ) it would take only 10sec to fetch 157 records.
can anyone give me some guide to solve this problem? thank you..
Code :
DECLARE
cursor cur1(l_startdate IN varchar2,l_enddate IN varchar2) IS
select * from shipment ship where ship.insertion_date >= to_date(l_startdate,'DD-MM-YYYY HH24:MI:SS') and ship.insertion_date < to_date(l_enddate ,'DD-MM-YYYY HH24:MI:SS')

Create dynamic table at runtime and bind it with ViewObject

Hi everyone.
I have the following task.
I need to create a multiple ViewObjects at runtime (using different constructed sql queries) and then bind ViewObjects with created (also in runtime) tables.
Tables are to be created on PanelTabbed component. Each tab contains one table.
So the problem - is there a way to perform this task?
A portion of code:
ApplicationModule am = ADFUtils.getApplicationModule("AppModule");
ViewObjectImpl vo = null;
if (am.findViewObject("SQLVo") != null)
am.findViewObject("SQLVo").remove();
System.out.println("object removed!");
vo = am.createViewObjectFromQueryStmt("vo", "select ...");
RichTable newTable = new RichTable();
newTable.setVar("row");
newTable.setVarStatus("rowStat");
RichShowDetailItem newDetItem = new RichShowDetailItem();
newDetItem.setText("New Detail");
newTable.setInlineStyle("width:100%;height:180px");
newTable.setRowSelection("single");
DCBindingContainer dcBindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
String iterBindingName = vo.getName() + "Iterator";
JUIteratorBinding iterBinding =
(JUIteratorBinding)dcBindings.findIteratorBinding(iterBindingName);
if (iterBinding != null) {
dcBindings.removeIteratorBinding(iterBindingName);
BindingContext bcc = (BindingContext)JSFUtils.resolveExpression("#{data}");
iterBinding =
new JUIteratorBinding(bcc.findDataControl("AppModuleDataControl"), vo);
String ctrlBindingName = vo.getName() + "Binding";
FacesCtrlHierBinding clonedHierBinding =
(FacesCtrlHierBinding)dcBindings.findCtrlBinding(ctrlBindingName);
if (clonedHierBinding != null) {
dcBindings.removeControlBinding(ctrlBindingName);
=======================================
Please, look here!
What's the best practices to create a new FacesCtrlHierBinding?
What a parameter _nodeBindings (type JUCtrlHierTypeBinding[]) should be?
=======================================
clonedHierBinding =
new FacesCtrlHierBinding(null,
iterBinding,
new String[]{
"BUILDING_ID"
// "BUILD_NAME",
// "FUNCTIONALITY_NAME",
// "CITY_NAME",

Shay, good day!
You answer is good, but - it use only one dynamic view (and one table, iterator and FacesModel).
I have task like topic started have - i need to create some unknows numbers of ViewObject (created by demad) and i must have a FacesModel for each created ViewObject.
How can we do it?
