JDev 10.1.2 ADF UIX - Help required in wrinting java code

Ok here is wher iam stuck.
I have used a method which is used to run search form.
That is the field name to be searched and the value is sent into this method.
The uix page is a master detail page.
So from the UIX page the user selects the field and the value, which is then sent to the customised method of mine.
The method code is as given below.
public final void setCourseRegistrationSearch(String p_field, String p_value)
ViewObject REGDETAILVO=findViewObject("RegistrationDetailView4");
ViewObject REGMASTERVO=findViewObject("RegistrationMasterView1");
if (p_value.equalsIgnoreCase(""))
String whereclause="1=1";
REGDETAILVO.setWhereClause(whereclause);
REGDETAILVO.executeQuery();
else
if( (p_field.equalsIgnoreCase("mod_name")))
String whereclause="reg_master_id in
(select reg_master_id from registration_detail where "
p_field"LIKE '%"+p_value+"%')";
REGMASTERVO.setWhereClause(whereclause);
REGMASTERVO.executeQuery();
if((p_field.equalsIgnoreCase("bt_description")))
String whereclause= "reg_master_id in
(select reg_master_id from registration_detail where bt_id in
(select bt_id from batch_timing where"
p_field" LIKE '%"+p_value+"%'))";
REGMASTERVO.setWhereClause(whereclause);;
REGMASTERVO.executeQuery();
Now when I use the first if statement where mod_name is filtered it works fine.
When I use the second option for bt_description its doesn't work.
The error i get is an oracle error which says missing right parenthesis.
So I checked through the debugger for the whereclause String.
There I found that the string gets trimmed to...
(select reg_master_id from registration_detail where bt_id in
(select bt_id from b
hence the error.
Could someone tell me why this is happening? Is there a workaround method for this?
Would be of great help.

Vineet

Solved it!! :-)
In the UIX page I check for the proxy in the event result, if it is there I take it, otherwise I take it from bindingcontext. Is this the right way to do it? Here is the UIX code:
                        <hGrid id="pptoHGrid" alternateText="No items were found"
                               treeData="${bindings.bindingContext['tree']}">
                          <boundAttribute name="proxy">
                            <if>
                              <comparison type="equals">

Help required in compiling Java Code.

I have java1.6 installed on my PC but I want to compile my code in such a way that
it will run on PCs with lower versions of java installed.
I am not using any feature specific to java1.6 in my program.
I am using Netbeans IDE 6.1
Thanks in advance.

Im not 100% sure of this but I would of thought a program will compile on any version of java as long as you dont use classes that are exclusive to higher version of java
for example i would think if you comiled the helloworld tutorial on v.1.6 it will run on computers with lower versions.
However a program which uses the scanner class (i think exclusive to 1.6 or 1.5 not sure though) will not run on say 1.2
CalypsoIve tested to run an complied class(version 1.6) on an computer with jre 1.5 installed(before), and it doesnt work. Dont remember precisly the error but it didnt run atleast.

hi i wonder how does jdk docs help as in writing java code because if i google a java code the jdk docs always becomes the result of my search but in my experience jdk docs never helps me.

Your question still does not make any sense, and you still haven't clarified what you're not understanding.
However, if you think that just by reading the API docs, with no other training or study, that you will be able to write that code, then you are seriously misunderstanding the purpose of the docs.
Obviously English is not your native language. You grew up speaking some other language at home and with your friends, and at some point in school or as private study, you started to learn English. You learned about the grammar and the alphabet and pronunciation, sentence structure, word order, etc. Now you have the basics of how the language works, and you know some words. When you want to learn new words to fit into the structure you have learned, you use a dictionary.
If you didn't study the grammar, sentence structure, etc., and just said, "I want to learn English. I will look at a dicationary," clearly that would not work.
Right?
So, since you now understand and agree with the English example, let me state something that I hope is obvious to you by now: The API docs are your dictionary. They are not a substitute for learning the language basics.
Furthermore, once you know the language basics in English and have your dictionary, you still won't know how to write a resume (which you may know as a CV). You will look at examples and perhaps take a course on resume (CV) writing. Just reading a dictionary won't help you write a resume(CV). Similarly, if you know some Java basics, you can't learn how to write a Swing app just by reading the Javadocs. You'll look at tutorials and examples. Then, once you know the basic structure of a Swing app, you'll look to the javadocs for more details about more kinds of GUI classes--different buttons and windows and panes and panels and layout managers, etc.

JDev 10.1.2 / ADF UIX: Approach to render data in levels/groups

Hi guys, I'm looking for ideas on how to use ADF (UIX and BO) to render (and let the user work with) a structure of 3 tables which have a parent->child->child-of-the-child relationship.
The need is to show a table with the parent in one row and below of it all its children and below of each children its own children. Also, the lowest level rows have numeric data which have to be summarized by the parent and so on upwards; and the lowest level rows should be selectable for edition in another page, and after edition return to the table.
Is the recommended approach to use the hGrid to do this?
Or should I use plain JSP and customized tags to achieve this (for easiness)?
Are there any other options?

Solved it!! :-)
In the UIX page I check for the proxy in the event result, if it is there I take it, otherwise I take it from bindingcontext. Is this the right way to do it? Here is the UIX code:

                               treeData="${bindings.bindingContext['tree']}">

ADF Faces: Making a selectOneChoice in java code?

I need to make a selectOneChoice to reuse in my pages (country selection) but can't seem to find how to do it on the web?
here is what i've attempted with the error output...
-------------------- the java code:
public void contextInitialized(ServletContextEvent event)
ServletContext servletContext = event.getServletContext();
Utils.log(servletContext, "Initializing Supply Chain Management System...");
// intitilize selectOne component
CoreSelectOneChoice countrySelectOne = new CoreSelectOneChoice();
List countrySelectItems = new ArrayList();
CountryCoordinator countryCoordinator = new CountryCoordinator();
try
List all = countryCoordinator.getAllCountries();
Iterator i = all.iterator();
for(;i.hasNext();)
Object object = i.next();
CoreSelectItem item = new CoreSelectItem();
item.setValue((Country)object);
item.setLabel(((Country)object).getCountry_name());
countrySelectItems.add(item);
// place the list of select items into the selectOne component
countrySelectOne.setValue(countrySelectItems);
servletContext.setAttribute("countrySelectOne", countrySelectOne);
Utils.log(servletContext, "Initializing Countries [SUCCESS]");
} catch(Exception e)
Utils.log(servletContext, "Initializing Countries [FAILED]");
Utils.log(servletContext, "Initialization complete...");
------------------------------ the JSP:
<af:selectOneChoice label="#{bundle.ADDRESS_COUNTRY}:" required="#{region_entity_address.required_entity_address_country}" binding="#{applicationScope.countrySelectOne}"/>
------------------------------ the error:
15:36:48,984 INFO [STDOUT] Sep 16, 2005 3:36:48 PM oracle.adfinternal.view.face
s.renderkit.core.xhtml.SimpleSelectOneRenderer _getSelectedIndex
WARNING: Could not find selected item matching value "CoreSelectItem[UINodeFaces
Bean, id=null]" in CoreSelectOneChoice[UIXEditableFacesBeanImpl, id=_id30]
....

That's right. JSF produces such IDs. They are causing problems with JAAS login forms, so we should use plain JSPs for login, but for the rest of the tasks such IDs are okay.
What I meant is that currenty the buttons are not rendered as
<input type="button" ... />but as pictures embedded in hyperlinks (<a>).
It's possible, though not likely, that in some future version of ADF Faces some component will be rendered as an HTML element that doesn't support tab ordering (although I haven't really considered if there are such elements). Then the trick with manually setting the tabIndex of the parent HTML element won't work.
Of course, I deeply appreciate the fact that you take the time to help us on this forum. In fact, I will go ahead and do just that -- I will dynamically set the tabIndex via JavaScript. I was simply wanting to make sure that I wasn't taking such a hack-like approach, if there was a better method.
Thank you again.

Download file from URL using ADF (urgent help required)

We have the following requirement:
On clicking a button we need to download the file present at a particular location(we have the URL).
I have written the following in .jspx file :
<af:commandButton id="btn1" >
                    <af:fileDownloadActionListener contentType="text/plain; charset=utf-8" method="#{bean.getFile}"/>
</af:commandButton>
The corresponding method in bean is :
public void getFile(FacesContext facesContext, OutputStream outputStream) {
HttpServletResponse response = null;
ServletOutputStream ouputStream = null;
currUrl = getFileURL("ID", 281);
response =
(HttpServletResponse)FacesContext.getCurrentInstance().getExternalContext().getResponse();
try {
ouputStream = response.getOutputStream();
ouputStream.write(this.getFileBytes(), 0,this.getFileBytes().length);
ouputStream.flush();
ouputStream.close();
} catch (IOException ioe) {
System.out.println("IO Exception");
public byte[] getFileBytes() {
URLConnection urlConn = null;
InputStream iStream = null;
URL url;
byte[] buf;
int byteRead;
try {
url= new URL("http://hjhj:34104/test.pdf");
urlConn = url.openConnection();
iStream = urlConn.getInputStream();
buf = new byte[5000000];
byteRead = iStream.read(buf);
if (byteRead > 0) {
System.out.println("Downloaded Successfully.");
return buf;
} catch (FileNotFoundException fnfe) {
System.out.println("File not found Exception");
fnfe.printStackTrace();
} catch (Exception e) {
System.out.println("Exception:" + e.getMessage());
e.printStackTrace();
} finally {
try {
iStream.close();
} catch (IOException e) {
System.out.println("IO Exception");
e.printStackTrace();
System.out.println("File");
return null;
The file is opening in same window but in some encrypted format. My requirement is to :
1. Have a pop (as in Mozilla or IE) which asks if I want to save the file or open.
2. Depending on that the file should be opened in pdf format and not in browser same window neither in browser tab.

Jdev version : 11.1.2.1.0
in .jspx file : we have a button. On clicking the button file from URL should be downloaded. I have used fileDownloadActionListener in commandButton. Corresponding code :
<af:commandButton id="btn1" >
                    <af:fileDownloadActionListener contentType="text/plain; charset=utf-8" method="#{bean.getFile}"/>
</af:commandButton>
in bean class : the method corresponding to fileDownloadActionListener is :
public void getFile(FacesContext facesContext, OutputStream outputStream) {
     HttpServletResponse response = null;
     ServletOutputStream ouputStream = null;
     response =(HttpServletResponse)FacesContext.getCurrentInstance().getExternalContext().getResponse();
     try {
          ouputStream = response.getOutputStream();
          ouputStream.write(this.getFileBytes(), 0,this.getFileBytes().length);

          ouputStream.close();

               System.out.println("IO Exception");
public byte[] getFileBytes() {
     URLConnection urlConn = null;
     InputStream iStream = null;
     URL url;
     byte[] buf;
     int byteRead;
     try {
          url= new URL("http://hjhj:34104/test");
          urlConn = url.openConnection();
          iStream = urlConn.getInputStream();
          buf = new byte[5000000];
          byteRead = iStream.read(buf);
          if (byteRead > 0) {
               System.out.println("Downloaded Successfully.");
          return buf;
    } catch (FileNotFoundException fnfe) {
          System.out.println("File not found Exception");
     } catch (Exception e) {
          System.out.println("IO Exception");
The URL given in the code is for a file which can be a PDF file or an EXCEL file.
My requirement is when i click the button:
1. A pop should come (as in Mozilla or IE) which asks if I want to save the file or open.
2. if i click on save file should save in a particular location.
3. if i click on open it should open as PDF/EXCEL format and NOT in browser.

Help required - running a Java program from the command line

Hi,
I have a small non-graphical Java application, packaged into a Jar file. My program relies on classes in another (external) Jar file.
When I run the application from the IDE, everything works fine. However, when I try to run the application from the command line, I keep getting a NoClassDefFoundError for classes in the external jar.
Both the application jar file and the external jar file are in my root directory (C:\).
My command line call is as follows:
java -cp c:MyExternalLib.jar -jar MyApp.jar
Any help greatly appreciated.

Help required!! Java WebService

Hello everyone.
I'm working in JAVA making a WebService using Netbeans IDE. The purpose of webservice is to call an API of another application to do some work. Now that application is installed in another server not on my local system. I am provided with a class file (input.class) to access that JAVA API of application.
Now my problem starts here that i downloaded that class file in my local system but i don't have that whole application. So i developed my webservice included that class too and build my webservice without any problem. Now when i deployed webservice at the server and tested it gives some errors.
javax.servlet.ServletException: java.lang.NoClassDefFoundError: input
com.sun.jersey.spi.container.servlet.WebComponent.service(WebComponent.java:371)
com.sun.jersey.spi.container.servlet.ServletContainer.service(ServletContainer.java:452)
com.sun.jersey.spi.container.servlet.ServletContainer.service(ServletContainer.java:633)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
I googled and found out to be classpath problem, but i set classpath too the same path from where i downloaded that class in application folder. but still its giving the same error. can anybody help me in this. ???????

Bottom line is that it cannot find your input.class. You need to make sure that whatever package that class has is in the same package as you place it.
So if the input.class was compiled with a package of com.mydomain.myproject, you need to put it in that folder structure.

Help required in endeca java application

Hi,
I am creating a java application of the endeca wine application. I am able to display the results but facing issue in creating the product links for individual products which we redirect me to the product detail page. How will the string query created append the R parameter to the query?
Pls let me know.
Thanks,
Vineet

There multiple ways you can do this
1. As you mentioned using R (Record Query) - where you should pass the endeca record ID, not the product ID for this to work
2. if you have unique product ids, you can use ntk param to look at only ID property and set ntt value as product id
hope this helps.

when the user puts in zero the program stops(while(hour!=0)).
I wrote the program but I have problem whit
Test class when the program computes first ,second and...weeks, and if the user don not put in zero the program must compute another persons salary
we should give new name new houre payement....
how do I use the same information for second person and computes his salary.
class Salary{
private String name;
private double hourPayment;
public Salary (String name, double hourPayment, ..){
this.name= name;
this.hourPayment=hourPayment;
public String getNamn(){
return name;}
public double getHourPayment(){
return hourPayment;
public double compute(int time){
if(time<=40){
normalSalary =(hourPayment*time);}
else if(time>40){
....=(((40*hourPayment)+(time-40)*(3/2)*hourPayment));
else if(timmar>70){
System.out.println("WARRNING:"+" "+"You have worked more than 30

The code you wrote only computes one week's salary. You need to wrap that inside loops that collect names, rates and hours. Here's some pseudocode to get you started:
get name
while name NOT ""
    get rate
    for i = 1 to 4
        get hours worked
        compute pay // this is the part you've coded
    next i
    get name
end while
