Transient vo attribute binding returning null
i have a editable form with multiple input text components which i created by dropping a collection on page.
now i want to add more fields which are transient and read only.
i added two transient attributes in VO with Updatable to Never and queryable to true, i dont have the logic yet so the expression is blank. i created a label using control hint.
now i created two attribute value bindings for these new fields.
i created two input text fields and used these bindings for their label , value properties. i set readonly and disabled both true for these input text fields.
if i hard code the label and value properties of input text it works, if i use binding expressions for them, it throws some error saying could not find binding for transient fileds or thery returned null.
what stpes should i use to add a transient field to a editable form.
jdev 11.1.1.5.0
Put the transient attributes into the underlying eo, refresh the vo and add the attributes from the eo to the vo. Now they should work just as any other attribute.

Need Help :: Current row attribute value returning null
Hi Frds,
I am facing the problem that
Current row attribute value returning null............ even though value is there..... plz.. he
This is the code in PFR
OAApplicationModule am = pageContext.getApplicationModule(webBean);
if (pageContext.getParameter("queryBtn")!= null)
String pPersonId = pageContext.getParameter("ctrlPersonId");
String rowReference = pageContext.getParameter(EVENT_SOURCE_ROW_REFERENCE);
OptionsVORowImpl curRow = ( OptionsVORowImpl) am.findRowByRef(rowReference);
String dtlsItem = (String)curRow.getFlexValue(); /* this is returning null value */
/* here creating the hashmap and calling the page with the hashmap*/
Thanks & Regards,

You want to catch Flexfield values?
Try below code for catch value.
OAApplicationModule am = pageContext.getApplicationModule(webBean);
if (pageContext.getParameter("queryBtn")!= null)
OADescriptiveFlexBean dfb = (OADescriptiveFlexBean)webBean.findChildRecursive("flexDFF"); //get the DFF bean
OAWebBean dffbean = (OAWebBean)dfb.findChildRecursive("flexDFF0"); //get the field that applies to the attribute1 column that is being rendered
OAMessageStyledTextBean Stylebean = (OAMessageStyledTextBean)dffbean;
String dtlsItem = (String)Stylebean.getText(pageContext);

Component binding return null value
I'm migrating a JSF 1.2 application to JSF 2.1, specificly I'm currently using mojorra 2.1.24.
The application consists of request scoped beans, and in order to pass data between requests, it embeds the data inside UI components.
The following behaviour works well with JSF 1.2, but not with JSF 2.1.
The application has the following configuration:
<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>client</param-value>
</context-param>
The page contains the following snippet:
<h:form prependId="false">
<h:inputHidden binding="#{bean.inputHidden}" />
<h:panelGroup rendered="#{bean.rendered}">
<h:commandLink value="onAction" action="#{bean.onAction}" />
</h:panelGroup>
</h:form>
The bean is the following:
@ManagedBean
@RequestScoped
public class Bean {
private UIInput inputHidden;
private AItem item;
public setInputHidden(UIInput inputHidden){
this.inputHidden = inputHidden;
if(item != null){ this.inputHidden.setValue(item); }
public AItem getItem(){
return (AItem) getInputHidden().getValue();
// other getter/setter
public String onNavToPage(AItem item){ this.item = item; return "page"; }
public String onAction(){ //... do something return ""; }
public boolean isRendered(){ return getProcessItem() != null; }
The steps are the following:
to navigate to page page the method bean.onNavToPage is invoked from within another page;
upon page rendering the bean.item is set as bean.inputHidden value;
after the page is diplayed, the command link is pressed.
At this point no command link is invoked, because the bean.inputHidden.getValue() returns null, and the command link is not processed.
I noticed that the inputHidden parameter passed to the setInputHidden method during restore view phase has, inputHidden.getValue() == null, no value has been saved previously in the view.
I would guess that something has changed in the component state management, but debugging the JSF code I didn't find what.
Debugging JSF code I found that the component state has been masked before the state has been saved in the view, so the ComponentStateHelper.saveState saves the deltaMap and not the defaultMap, where all the state has been put.
public Object saveState(FacesContext context) {
if (context == null) {
throw new NullPointerException();
if(component.initialStateMarked()) {
return saveMap(context, deltaMap);
else {
return saveMap(context, defaultMap);
is this a bug?
If not, how can I restore JSF 1.2 behaviuor and save the defaultMap?

Command Link attribute is returning null.
Hi all,
I have a pojo iterator with me. I have to generate command link for a attribute from that iterator. I generated them using a ForEach loop as below and put address of employee as an attribute of that tag. Now in the Action Listener i am fetching this attribute using actionEvent as below : -
public void displayUploadAttachment(ActionEvent actionEvent) {
System.out.println("Content Id:- "+actionEvent.getComponent().getAttributes().get("adr"));
My action Listener returns it as NULL. I am not getting why it is doing this.
<af:forEach items="#{bindings.myEmpIterator.children}"
var="emp">
<af:commandLink text="#{emp.firstName}" partialSubmit="true" id="cl22"
actionListener="#{viewScope.empBean.displayEmpAddress}">
<f:attribute name="adr" value="#{emp.address}"/>
</af:commandLink>
</af:forEach>
J dev version
Studio Edition Version 11.1.1.6.0Hi,
Couple of things to check.
1. Check if the address is really null (instead of #{emp.firstName} as text for the commandLink, try with #{emp.address}).
2. Instead of
System.out.println("Content Id:- "+actionEvent.getComponent().getAttributes().get("adr"));
try
System.out.println("Content Id:- "+((RichCommandLink)actionEvent.getSource()).getAttributes().get("adr"));

Get attribute name from VO returns null.
Hello,
I'm using JDeveloper 11.1.1.3. I have an af:inputfile component in which i set a ValueChangeListener. I'm using the attribute "Filename" from the form view to set the name of the file before saving it to a directory. At first, i had a different layout for my jspx page (very similar in design) and everything was working perfectly. When i redesigned the page, i'm now getting "null" as the filename. I'm not able to get the attribute! Although i didn't change anything in the code! I tried writing a simple method to output the attribute:
public String justOutput(){
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
AttributeBinding attr = (AttributeBinding) bindings.getControlBinding("Filename");
if (attr == null)
return null;
String filename = (String) attr.getInputValue();
System.out.print(filename);
return null;
}It was able to output the attribute. But in my original method i'm getting "null".
******Another important observation*******
If i pressed upload another time at runtime and uploaded another file it works again!
Here is my code:
public void uploadFile(ValueChangeEvent valueChangeEvent) {
InputStream in;
FileOutputStream out;
ExternalContext context = FacesContext.getCurrentInstance().getExternalContext();
String fileLoc = context.getInitParameter("DATA_DIR");
UploadedFile file= (UploadedFile)valueChangeEvent.getNewValue();
boolean exists = (new File(fileLoc)).exists();
if(!exists){
(new File(fileLoc)).mkdirs();
if(file != null && file.getLength() > 0){
FacesContext context2 = FacesContext.getCurrentInstance();
FacesMessage message = new FacesMessage("File Uploaded" + file.getFilename() +
"(" + file.getLength() + "bytes)");
//context2.addMessage(valueChangeEvent.getComponent().getClientId(context2), message);
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
AttributeBinding attr = (AttributeBinding) bindings.getControlBinding("Filename");
if (attr == null)
return;
String filename = (String) attr.getInputValue();
try {
out = new FileOutputStream("C:\\demos\\" + filename + ".pdf");
in = file.getInputStream();
for (int bytes=0; bytes < file.getLength(); bytes++) {
out.write(in.read());
in.close();
out.close();
} catch (IOException e) {
e.printStackTrace();
else {
String filename = file != null ? file.getFilename():null;
String byteLength = file != null ? "" + file.getLength():"0";
}I don't think the code is wrong because it worked before. But why is this happening?
Can anyone please help!?
Mohamed.Sorry for the late reply Frank,
Thanks for your reply, no i didn't! But it worked when i set the 'autosubmit' property to true... Like you said:
the name field hasn't updated the model to the time you try and access itThanks again.

Binding for "File Content Repository Path" is returning null value
I have created a data control for file based content repository based on an existing file system path. *But when this data contol is invoked the command "#{bindings['getURI_returnURI'].inputValue}" is returning null.*+
Please advice what are possible scenarios. I have performed the following
#1. Create a file system folder in windows XP named "C:\CPContentRepository" and add some html pages into this folder.
#2. Create a "content" project in the application.
#3. Create a "Content Repository Data Control" named "CPFileContentRepository". Repository Type : "File System", Base Path : "C:\CPContentRepository". Test & Registration is successful.
#4. Add a "panel horizontal" into jsf jsp "ContentTest" page & drap-dop data control "CPFileContentRepository--> getURI(String)--> Return--> URI". select return type as "ADF Output Text".
#5. Edit Authorization of the "ContentTest" page definition for "View --> anyone".
#6. Edit Authorization of the "ContentTest" page definition bindings "getURI" for "Invoke --> anyone".
#7. Run the "ContentTest" page. The output for the page is empty.
Regards,
VikkiThere're two major problems in your code. One you have used different names to get your parameters like in your first jsp they're like
<input type="text" name="did" size="20" </p>
<p align="center"> </p>
<p align="center"><b>Name </b>
<input type="text" name="name" size="20"></p>
<p align="center"> </p>
<p align="center"><b>Specialist In
<input type="text" name="specialist" size="20"></b></p>
<p align="center"> </p>
<p align="center"><b>Address
<input type="text" name="address" size="20"></b></p>
<p align="center"> </p>
<p align="center"><b>Phone no.
<input type="text" name="phno" size="20"></b></p>
<p align="center"> </p>but when you're getting you're doing it like this
String name = request.getParameter("name");
String did = request.getString("did");
String add = request.getParameter("add");
String specilist = request.getParameter("specilist");
String phno = request.getParameter("phno");First get them with same name as you have them in your first jsp. another thing in that you're not used form tag in write way... You have created submit button in some other form
and when you're pressing submit button actully you're submitting only that form value and your form1 is not submitted that's why you're getting null values for
those parameters you're getting with right name -
Using table filters with transient VO attributes
Hi,
I have a the following use case and I cannot seem to find a valid solution on my own without falling into deep depression and/or psychotic delirium. Anyway, I'm sure there's a solution and that it's pretty simple, and hopefully someone here will know it.
Let say I have a read-only VO with two attributes bound to the SQL query, namely Prefix and Suffix, as well as a transient calculated attribute named Compound formed of both the Prefix and Suffix separated with an hyphen.
Now I want to bind that VO to an af:table supporting filters, showing only Compound column as Prefix and Suffix alone doesn't make much sense to the end user. I therefore use Compound as the sortProperty. For sorting, I was able to enforce correct logic by overriding the VO's getOrderByClause and setOrderByClause methods. For findMode, an old solution proposed by Steve involving overriding createViewCriteria with a custom class extending ViewCriteria that needs to override createViewCriteriaRow works. However, the filter capability of the table seems to use something different involving ViewCriteriaItemValue. Although I would be able to create a different instance when a criterion is created for the Compound attribute, but even if I do, I don't know how to split that value into two columns afterward. I guess I could create three linked values when the compound filter value is created, but it seems complicated. Best would be to hook the method returning the list of ViewCriteriaItemValue during the where clause creation, but then again, the data binding layer use that to detect what filters are applied and output the table accordingly so I cannot really remove the compound value at that point either. I could also override the getWhereClause I guess. Another solution, the simplest, would be to put the compound value in the SQL query, but I find that option appalling as it shouldn't be the database responsibility. If there's no other option I guess that what I'm going to do however.
Anyone can shred any light on that issue?
Regards,
~ SimonHi Peter,
Although it's not exactly what I need, I can indeed build a solution from that. Then again, it wouldn't be my first choice as it doesn't respect a correct separation of concerns (I guess I'm a purist). A listener is a view/controller layer entity and I would have preferred to hide the fact that the VO Attribute is a composition of two others to that layer. I would really have liked a pure model layer solution. That being said, I prefer the queryListener option to the Database one.
Thanks,

GetAttribute() method of a view object is returning NULL
Hi ,
I am trying to implement PPR in one of my OAF page and I have taken the following approach.
I have declared the follwing transient boolean attribute in the VO() apart from the existing attribute "Meaning" .
1.MfgEnttity
2.MfgAcct
3.MfgSubAcct
4.MfgCc
5.MfgProj
In the page I have used these attributes in the rendered property as "${oa.XXR2RMfgproSegVO.MfgSubAcct}" like this.
Now in the CO I have written the following code.
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
am.invokeMethod("initializeXXR2RMfgproSegVO");
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
String event = pageContext.getParameter(EVENT_PARAM);
String source = pageContext.getParameter(SOURCE_PARAM);
OAApplicationModule am = (OAApplicationModule)pageContext.getApplicationModule(webBean);
am.invokeMethod("handleSegmentChangeEvent");
And the AM code is as follows:
public void initializeXXR2RMfgproSegVO()
OAViewObject vo = getXXR2RMfgproSegVO();
if(!vo.isPreparedForExecution())
vo.executeQuery();
Row row = vo.createRow();
vo.insertRow(row);
row.setNewRowState(Row.STATUS_INITIALIZED);
public void handleSegmentChangeEvent()
OAViewObject pVO = (OAViewObject)findViewObject("XXR2RMfgproSegVO");
OARow hdrRow = (OARow)pVO.getCurrentRow();
String status = (String)hdrRow.getAttribute("Meaning");
System.out.println("poRow "+ hdrRow.toString());
System.out.println("value of the status is "+ status);
if("Entity".equals(status))
hdrRow.setAttribute("MfgEnttity", Boolean.TRUE);
hdrRow.setAttribute("MfgAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgSubAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgCc", Boolean.FALSE);
hdrRow.setAttribute("MfgProj", Boolean.FALSE);
} else
if("Account".equals(status))
hdrRow.setAttribute("MfgEnttity", Boolean.FALSE);
hdrRow.setAttribute("MfgAcct", Boolean.TRUE);
hdrRow.setAttribute("MfgSubAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgCc", Boolean.FALSE);
hdrRow.setAttribute("MfgProj", Boolean.FALSE);
}else
if("Subaccount".equals(status))
hdrRow.setAttribute("MfgEnttity", Boolean.FALSE);
hdrRow.setAttribute("MfgAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgSubAcct", Boolean.TRUE);
hdrRow.setAttribute("MfgCc", Boolean.FALSE);
hdrRow.setAttribute("MfgProj", Boolean.FALSE);
}else
if("Cost Center".equals(status))
hdrRow.setAttribute("MfgEnttity", Boolean.FALSE);
hdrRow.setAttribute("MfgAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgSubAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgCc", Boolean.TRUE);
hdrRow.setAttribute("MfgProj", Boolean.FALSE);
} else
if("Project".equals(status))
hdrRow.setAttribute("MfgEnttity", Boolean.FALSE);
hdrRow.setAttribute("MfgAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgSubAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgCc", Boolean.FALSE);
hdrRow.setAttribute("MfgProj", Boolean.TRUE);
else
hdrRow.setAttribute("MfgEnttity", Boolean.FALSE);
hdrRow.setAttribute("MfgAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgSubAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgCc", Boolean.FALSE);
hdrRow.setAttribute("MfgProj", Boolean.FALSE);
Now when in the page I am changing the value of the attribute "Meaning" it is always getting into the else part i.e. where all the attributes are "False".
The two System.out.Println statements are returning the follwing values.
10/03/22 15:41:08 poRow [email protected]3
10/03/22 15:41:08 value of the status is null
Can you please suggest why this "Status" is returning NULL and how I can get the current row selected in the page?
Thanks
SubhabrataHi Pratap,
Thanks a lot for your reply.
Can you please suggest how can I rectify the code.I have tried commenting the AM code as follows
public void initializeXXR2RMfgproSegVO()
OAViewObject vo = getXXR2RMfgproSegVO();
if(!vo.isPreparedForExecution())
vo.executeQuery();
//Row row = vo.createRow();
//vo.insertRow(row);
//row.setNewRowState(Row.STATUS_INITIALIZED);
But in the page when I am selecting any segment its throwing Null pointer Exception.
I am new in OAF and this is an urgent client requirement.Please suggest me Where exactly I need to make change in my code.
Thanks in advance...
Thanks

Iterator Binding + Attribute binding problem
I have created a SelectOneListbox and an associated attirute binding in my pagedef. When I try to access the changed value in my managed bean event handler method - I get a null object. However the index for the changed value is passed fine.
tempIter.getRowAtRangeIndex( index ) returns a null object.
I tried using attribute binding - that does not work either.
Managed bean:
public void productChange(ValueChangeEvent valueChangeEvent) {
// Add event code here...
BindingContainer bc = this.getBindings();
// get the selected department
DCIteratorBinding tempIter = (DCIteratorBinding) bc.get("TempIterator");
if ( tempIter != null ){
Object newVal= (Object)valueChangeEvent.getNewValue();
System.out.println("New Product value:"+newVal);
String ss = (String)newVal.toString();
Row rw = tempIter.getRowAtRangeIndex(Integer.parseInt(ss));
if ( rw!=null ) {
String[] attrs = rw.getAttributeNames();
//Object prodName = (Object) rw.getAttribute("ProdId");
System.out.println(" Attribute value:"+ attrs);
} else System.out.println(" Null row ");
//trying to get value from attribute binding
AttributeBinding prodIdBinding =
(AttributeBinding)getBindings().getControlBinding("TempId");
if ( prodIdBinding != null){
Object deptId = (Object)prodIdBinding.getInputValue();
if ( deptId != null)
System.out.println("Finally value:"+deptId.toString());
else
System.out.println("Cant access value for department id");
} else System.out.println("**********Product id binding is null");

Dynamic Declarative Component managed bean returned null
Hi,
In a project from an application a DDC component is defined. This component uses a managed/backing bean with view scope.
Using this component inside this project is working fine. This component should be used in other view controller projects, and here where the problems are.
This project(let's call it Common) is deployed as ADF Library jar, and used in the other V-C projects.
The big problem is that the managed bean defined for the logic of this component is not 'reacheable'.
(Another problem is that the attribute value is not seen as its EL expression but as string, for this i found a workaround.)
In project Common the adfc-config.xml file:
<adfc-config xmlns="http://xmlns.oracle.com/adf/controller" version="1.2">
<managed-bean id="__4">
<managed-bean-name id="__2">ExtendedShuttle</managed-bean-name>

<managed-bean-scope id="__3">view</managed-bean-scope>
</managed-bean>
</adfc-config>A part from component declaration:
<af:table var="row" rowBandingInterval="0" id="ta"
rowSelection="multiple" columnStretching="last"
disableColumnReordering="true" fetchSize="-1"

Can you help figure it out, why is not working or why the managed bean is not visible in other projects but only in the one where the component is defined?
Thank you for your time,
Bogdan
ps: how can i format the source code, on this fourm?Hi Frank,
Thank you for the answer.
I must say i'm quite new with ADF technology and maybe my questions are silly.
Here is a Quote from "Oracle Fusion Developer Guide - Building Rich Internet Application with Oracle ADF" by Frank Nimphius and Lynn Munsinger Chapter 15 page 498:
"You build dynamic declarative components *instead* of tag library based declarative components, if component resuse is required *only within the application* that has the component defined."
Maybe i misunderstand the meaning of application from this sentence, but i need this component in several ViewController projects from only one application (ADF application).
Tag lib declarative component I would not like to have, since the (automtically) build process is not my responsability and it will take some time till is pinpointed, but still is a last resort.
Anyway two things are strange:
1. Why the component is still available in other projects(and the beans not)?
2. Why when a binding variable (for example: of type FaceCtrlHierBinding) has the correct type in the declarative project and in the order projects is of type String and its value is the variable name?
Example:
<af:declarativeComponent ...
AllItems="#{bindings.Action}"
In project where the component is declared its value is an instance of FacesCtrlHierBinding and in the rest of the projects is of type String with value "Action".
Once again thank you a lot,
Bogdan -
Getfilteredrows("selectFlag","Y") returns null (Urgent)
Hi,
I have created an advanced table on a view object. I created a transient attribute called selectflag with updatable as true. I have one of the column on the above table as link which will show basically details of each row.
In order to populate the details page, I have to pass row number which is one of the column. So I am using getfilieteredrows("selectflag","Y") to retrieve the current selected row.
but the voimpl.getfilieteredrows("selectflag","Y") is returning null.
Should I need to do any more settings on transient attribute.
Your help on this is higly appreciated.When you click on the image it's a redirect and not a post so it will not enter processFormRequest. processRequest will be entered during the initial rendering cycle of the page so at that time nothing was selected because your page didnot render yet.
As I mentioned in my earlier mail you need to append the additional parameter of the primary key to identify the row. Where are you deleting the record, in the subsequent page or trying to do this in this page's processFormRequest ?
You donot need a radio button at all if you want to use the image. You can also make a form submit by setting fireAction property and set the parameter in the propert inspector instead of appending the primary key. -
FindNode returning Null And XML Not Accepting Special Characters
Hi All,
i am trying the get the attribute value in the element "ns4:InfoCFDi" using FindNode method, but the method is returning NULL. I used the same code for other sample as well and was successfull. but for this specific XML file(which is below) I am getting a Null.
i can get till S:Body, but when i try to use FindNode for ":Body/s4:ResponseGeneraCFDi" I get Null value.
And I used "S:Body/*[local-name()=" | "ns4:ResponseGeneraCFDi" | "]";
as mentioned in other post but still no success.
==>I Have one more question relating to special characters. I need to use characters such as - ó in my XML to read as well as write. When I try to read i am getting XML parse error and when writing, i cannot open the file properly.
Your help is much appreciated.
My code is here:
Local XmlDoc &inXMLDoc, &reqxmldoc;
Local XmlNode &RecordNode;
&inXMLDoc = CreateXmlDoc();
&ret = &inXMLDoc.ParseXmlFromURL("D:\Agnel\Mexico Debit Memo\REALRESPONSE.xml");
If &ret Then
&RecordNode = &inXMLDoc.DocumentElement.FindNode("" );
If &RecordNode.IsNull Then
Warning MsgGet(0, 0, "Agnel FindNode not found.");
rem MessageBox(0, "", 0, 0, "FindNode not found");
Else
&qrValue = &RecordNode.GetAttributeValue("asignaFolio ");
Warning MsgGet(0, 0, "asignaFolio." | &qrValue);
End-If;
Else
Warning MsgGet(0, 0, "Error. ParseXmlString");

TIAFirst of all you have to supply a value you want to search for and this has to be the complete path to the value. You're saying you already tried that, but can you paste the code which you used for that? I don't see the path mentioned in the code you posted.
*FindNode*
Syntax
FindNode(Path)
Description
Use the FindNode method to return a reference to an XmlNode.
The path is specified as the list of tag names, to the node that you want to find, each separated by a slash (/).
Parameters
Path
Specify the tag names up to and including the name of the node that you want returned, starting with a slash and each separated by a slash (/). This is known as the XPath query language.>
Another option would be this snippet of code:
&InfoCFDiArray = GetElementsByTagName("ns4:InfoCFDi");
&InfoCFDiNode = &InfoCFDiArray [1];
&attValue = &InfoCFDiNode.GetAttributeValue("noCertificadoSAT")
Warning(&attValue);
It creates an array of XML Nodes which match the name "ns4:InfoCFDi". Since there's only one in the XML it's safe to assume it will be the one and only node in the array. I've assigned that node to the variable &InfoCFDiNode and use that to retrieve the attribute "noCertificadoSAT" value. The warning message should display the value supplied there.
Concering the special characters; you will have to change the encoding of the XML. Peoplecode sets this to UTF-8 by default, but doesn't include this in the header. There's a little hack for that somewhere on the web, I'll see if I can find it. -
GetConnectionURL returns null in Bluetooth Application
Hi,
I am trying to make my first steps with the JSR-82 API on mobile phones
(Nokia 6680 and Sony Ericsson W800i). I have written a simple program
(see code below), which is supposed to discover near-by devices, search
for a given service (UUID) on a chosen (previously discovered) device
(=server) and then to connect to the server and send a byte (n) to it. The
server should then in turn send n+1 back. All this should be done using
RFCOMM.
The code works fine in the emulator as well as on two Nokia phones and
on two SE phones. It further works, when using a Nokia phone as the
server and a SE phone as the client. However, when using a SE as the
client and a Nokia as the server, the call to getConnectionURL() returns
null instead of a valid URL that can be used to set up the connection
(you can find this piece of code in the ClientThread class). Can somebody
explain me what I am doing wrong?
Thanks,
Michael
P.S.:At first I thought it might be a compatibility problem, but in the
BluetoothDemo program that comes with WTK2.2 the correct URL ist
returned by getConnectionURL() (have other problems with this example
though, when it comes to download images, in particular...).

and here is the servlet code:
public class AddDVDServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// System.out.println("in AddDVDServlet post method");
List errorMsgs = new LinkedList();

DVDItem dvd = new DVDItem(title,year,genre);
request.setAttribute("dvdItem",dvd);
RequestDispatcher rd = request.getRequestDispatcher("success.view");
rd.forward(request, response);
catch(Exception e){
errorMsgs.add(e.getMessage());
request.setAttribute("errors",errorMsgs);
RequestDispatcher rd = request.getRequestDispatcher("error.view");
rd.forward(request, response);
e.printStackTrace();
System.out.println("exception:"+e);
why does getParameter always return null??? whats wrong?I don't know. However, I suspect that because you have a tag with the same name as 'title', its causing a name conflict. Chnage the name to something else. If it works, then that's the likely explaination.

Managed bean returns null on SetActionListener
Hi,
I'm trying to implement a filter for my table (something similar to what's done in the "OracleAS 10g R3: Oracle ADF for Forms/4GL Developers/Volume II" student guide, practice 9-5). The idea is to have a request-scoped managed bean which holds the filter value - the value is set using a SetActionListener, and later bound to a bind variable in a view with a view criteria. I have problem re-creating this in Trinidad (JDev 11 TP3, to be exact).
I have created a request-scoped bean in adfc-config.xml (called 'ecnStatusBean'), with a managed property (named 'Status'). I am referencing it from my SetActionListener: setting #{'E'} to #{requestScope.ecnStatusBean.Status}. The reference compiles fine in the Expression Builder (it didn't before I created the managed bean), but when running and clicking the CommandLink with the SetActionListener, I get a runtime error:
oracle.security.jazn.JAZNRuntimeException: Target Unreachable, 'ecnStatusBean' returned null
at oracle.security.jazn.oc4j.JAZNFilter.doFilter(JAZNFilter.java:480)
To make things more interesting, I tried changing the scope to session, and got a different error:
oracle.adf.controller.ControllerException: ADFC-10001: Cannot instantiate class 'pelephone.cdma_ecn.ecn_manager.model.ecnStatusMB'.
at oracle.adfinternal.controller.util.Utils.createAndLogFacesException(Utils.java:169)
Am I doing a rookie's mistake? Is this a Trinidad issue? Something else?
Thanks in advance for any help,
BorisAre you sure about the reference you use here: #{requestScope.ecnStatusBean.Status}.
Here is a simple sample of what works for me:
The first page has this:
<af:form binding="#{backing_start.form1}" id="form1">
<af:inputText label="Label 1" binding="#{backing_start.inputText1}"
id="inputText1"/>
<af:commandButton text="commandButton 1"
binding="#{backing_start.commandButton1}"
id="commandButton1" action="go">
<af:setActionListener from="#{backing_start.inputText1.value}"
to="#{backing_start.paramToPass}"/>
</af:commandButton>
</af:form>It references a bean that has this:
private RichInputText inputText1;
public void setInputText1(RichInputText inputText1) {
