Command link / button action is not taking place if i use it in iterator.

Hi,
I am new to ADF, i am facing 1 issue while implementing ADF mobile browser application.
Issue: command link / button action is not taking place if i use it in iterator. its just refreshing the page it self and displaying as no records.
Scenario is i am populating the search results in results page from search page using iterator, i want to get the complete details in different page (results page -> details page) .
I have tried in different ways.like
case1:
<tr:panelGroupLayout id="pgl2" layout="vertical" styleClass="af_m_panelBase">
<tr:panelHeader text="#{classviewBundle.SEARCH_RESULTS}" id="ph1"/>
<tr:iterator id="i1" value="#{bindings.SubjectVO1.collectionModel}" var="subject"
varStatus="subIndx" rows="100">
<tr:panelBox text="#{subject.Subject} #{subject.CatalogNbr} - #{subject.CourseTitleLong}"
styleClass="af_m_listingPrimaryDetails" id="pb1">
<f:facet name="toolbar"/>
<tr:table var="ssrClass" rowBandingInterval="1" id="t1" value="#{subject.children}"
varStatus="clsIndx" rowSelection="none"
binding="#{SessionBean.subjectTable}" verticalGridVisible="true"
emptyText="No Records" width="100%">
<tr:column id="c9" sortable="false" styleClass="width:100%">
<*tr:commandLink text="Section: #{ssrClass.ClassSection}-#{ssrClass.SsrComponentLovDescr} (#{ssrClass.ClassNbr})"*
id="commandLink2" styleClass="af_m_listingLink"
*action="#{pageFlowScope.BackingBean.searchaction}"></tr:commandLink>*
//remaining code
in this case commandlink action is not able to invoke serachaction() method
case 2:
<tr:commandLink text="Section: #{ssrClass.ClassSection}-#{ssrClass.SsrComponentLovDescr} (#{ssrClass.ClassNbr})"
id="commandLink2" styleClass="af_m_listingLink"
action="classdetails}"></tr:commandLink>
in this case its not able to navigate to classdetails page.
I gave correct navigation cases and rules in taskflow,but its working fine when the command link is out of iterator only.
i tried with actionlistener too.. but no use.. please help me out of this problem .
*Update to issue:*
The actual issue is when i use command link/button in an table/iterator whose parent tag is another iterator then the action is not taking place.
the structer of my code is
< iterator1>
#command link action1
< iterator2>
#command link action2
</ iterator2>
< /iterator1>
#command link action1 is working but "#command link action2" is not...
Thanks

Hi,
To solve my problem I used a af:foreach instead.
<af:forEach items="#{viewScope.DataBySubjectServiceBean.toArray}" var="text">
<af:commandLink text="#{text.IndTextEn}" action="indicator-selected" id="cl1">
<af:setActionListener from="#{text.IndCode}" to="#{pageFlowScope.IndicatorCodeParam}" />
</af:commandLink>
</af:forEach>
By the way you need to convert the iterator to an Array using a ManagedBean.
public Object[] toArray() {
CollectionModel cm = (CollectionModel) getEL("#{bindings.TView1.collectionModel}");
indicators = new Object[cm.getRowCount()];
for(int i=0;i<cm.getRowCount();i++){
indicators[i] = cm.getRowData(i);
return indicators;
public static Object getEL(String expr) {
FacesContext fc = FacesContext.getCurrentInstance();
return fc.getApplication().evaluateExpressionGet(fc,expr,Object.class);
Hope that helps-

Any suggestions Plz??

As the [HTML specification|http://www.w3.org/TR/html401/interact/forms.html] states, you should be setting the enctype to multipart/form-data to be able to upload files to the server. In the server side, you need to process the multipart/form-data binary stream by parsing the HttpServletRequest#getInputStream(). It is a lot of work to get it to work flawlessly. There are 3rd party API's around which can do that for you, such as [Apache Commons FileUpload|http://commons.apache.org/fileupload] (carefully read the User Guide how to use it).
You can also consider to use a Filter which makes use of the FileUpload API to preprocess the request so that you can continue writing the servlet code as usual. Here is an example: [http://balusc.blogspot.com/2007/11/multipartfilter.html].

Insert data into table from JSP page using Entity Beans(EJB 3.0)

I want to insert data into a database table from JSP page using Entity Beans(EJB 3.0).
1. I have a table 'FRIENDS', (in Oracle 10g database).
2. It has two columns, 'NAME' and 'CITY'. Both have datatype strings(varchar2).
3. Now from a JSP page, having two textfields, 'NAME' and 'CITY', I want to insert data into table 'FRIENDS'.
4. In between JSP and database is a Entity Bean(EJB 3.0) and a stateless session bean.
5. I am using JDev as editor.
Please provide me code ASAP or link with similar example.

Help needed to create a master-detail JSP page using OAF.

I like to create a master-detail JSP page using OAF. If any help or guide will be appreciate.
- Kausik

A Master Detail Page is a basically a game between two VOs(Master and Detail mostly connected through a View Link). You can also have a look at the View Link section in the Dev guide. Page Layouts is one thing which you can take a call yourself.

Do paging with header on a JSP page

Hi:
We have a data report displayed as a JSP page. The report displays 200 rows of data. We need to print these 200 rows report with a header/title on each page. And our user only wants to hit he Browser print button once. This would have been easy if we don't have to insert the header on each print page. But how can we print this multiple page report with a header? Do we need to use CSS? any help will be appreciated.
reportPrinter

Okay bear with me:
Step 1: determine how many rows in a table with a header will print on a single page
Step 2: Create a jsp that breaks your data down into tables of the row size determined above.
For example if the data consists of 1000 rows and 50 rows w/ headers will fit on a page
then the jsp will create 20 tables of 50 rows w/ headers each.
Step 3: Use CSS to put page breaks between the tables.
http://www.htmlgoodies.com/beyond/css_print.html
Step 4: In the original JSP use the HTML LINK tag to link it to the JSP you just created
http://www.gself.com/xbas/head/linking.htm
<link rel="alternative" href="{new JSP url}" type="text/html" media="print" />
Step 5: On the original JSP provide a button that when clicked on will call the JavaScript print function.
Now what should happen is that when the button on the original JSP is clicked the JavaScript print function will be called but instead of the page displayed in the browser being printed the alternative page
in the LINK tag will get printed. This alternative JSP page is formatted to print one table with headers per page.
The only part of this that I have not used in a production web app iss the CSS page break part. The rest of it I know will work.

Help with Jtext fields on JSP page?

Hi All,
How can I collect an integer on a JSP page from user input?
I am looking to vallidate the user input also thought about vallidating using HTML then passing/casting the input to a Java variable for further manipulation on the page.
I cannot use response.encodeUrl for this.
Effectively what I would like to do is replicate what a JTextField with an action listener would do to retrieve user input in a desktop Java application.
Any ideas and help would be welcome.
regards
Jim Ascroft

Hi All ,
I propbably didnt put my questions all that well.
So I wil try to be more specific.
1.How can I collect an integer on a JSP page from user input?
I am looking to vallidate the user input. I thought about vallidating using HTML then passing/casting the input to a Java variable for further manipulation on the page.
I cannot use response.encodeUrl for this.
2.I understand that my Java helper classes are compiled into .class files and then used by the JSP page as required. Also the Java code within the <% %> Java tags is recognised and runs .
So if the java between the <% %> tags can be compiled and used why can other Java components eg Swing or AWT not be used in the same way?
Effectively what I would like to do is replicate what a JTextField with an action listener would do to retrieve user input in a desktop Java application.
Any ideas and help would be welcome.

Problem with displaying BLOB images on JSP page using a servlet

hi. I have a big problem with displaying BLOB images using JSP. I have a servlet that connects to the oracle database, gets a BLOB image , reads it, and then displays it using a BinaryStream. The problem is , this works only when i directly call that servlet, that is http://localhost:8080/ImageServlet. It doesn't work when i try to use that servlet to display my image on my JSP page (my JSP page displays only a broken-image icon ) I tried several coding approaches with my servlet (used both Blob and BLOB objects), and they work just fine as long as i display images explicitly using only the servlet.
Here's what i use : ORACLE 10g XE , Eclipse 3.1.2, Tomcat 5.5.16 , JDK 1.5
here is one of my image servlet's working versions (the essential part of it) :
               BLOB blob=null;
          rset=st.executeQuery("SELECT * FROM IMAGES WHERE ID=1");
          while (rset.next())
               blob=((OracleResultSet)rset).getBLOB(2);
          response.reset();
          response.setContentType("image/jpeg");
          response.addHeader("Content-Disposition","filename=42.jpeg");
                ServletOutputStream ostr=response.getOutputStream();
               InputStream istr=blob.getBinaryStream(1L);
                int size=blob.getBufferSize();
          int len=-1;
                byte[] buff = new byte[size];
                     while ((len=istr.read( buff ))!=-1 ) {
               ostr.write(buff,0,len);
         response.flushBuffer();
         ostr.close(); and my JSP page code :
<img src="/ImageServlet" border="0" > If you could just tell me what i'm doing wrong here , or if you could show me your own solutions to that problem , i would be very greatful ,cos i'm realy stuck here , and i'm rather pressed for time too. Hope someone can help.

I turns out that it wasn't that big of a problem after all. All i had to do was to take the above code and place it into another JSP page instead of into a servlet like i did before. Then i just used that page as a source for my IMG tag in my first JSP. It works perfectly well. Why this doesn't work for servlets i still don't know, but it's not a problem form me anymore . Ofcourse if someone knows the answer , go ahead and write. I would still appriceatte it.
here's the magic tag : <img src="ImageJSP.jsp" border="0" > enjoy : )

Problem with bean in a JSP page

I have developped a JSP pages in wich I call a bean with
<jsp:useBean id="db" scope="request" class="SQLBean.class" />
The bean SQLBean.class is in the same directory as the JSP page.
When I execute the JSP, I have the following error:
SQLBean.class db = (SQLBean.class) JSPRuntime.instantiateBean("db", "SQLBean.class", "request", __db_was_created, pageContext, request, session, application);
Syntax error: [expected after this token
Syntax error: "]" inserted to complete ArrayAccess
Syntax error: "AssignmentOperator AssignmentExpression" inserted to complete StatementExpression
I use JRUN with IIS
Thanks for the help

I am assuming your class name is SQLBean.
use:
<jsp:useBean id="db" scope="request" class="SQLBean" />
instead of:
<jsp:useBean id="db" scope="request" class="SQLBean.class" />

Using a Statefull Session Bean with RMI on Multiple JSP pages

Heya all,
i have a JBoss server running with a statefull bean on it. I want to use it on my JSP pages. But every time I start my JSP-page a NEW INSTANTION of the bean is created! For each user using my page, I want ONE bean.
Is there anyway to do this? ANything with the sessioncontext?
I can do it with local beans, using the simple tags in the JSP-page, but they do not work for Remote Beans.
(I use JNDI)

hi,
statefull session beans are client session specific. the instance will exists if client session exits.
now since u are loading the jsp page again in the other browser, a new instance will be associated with the current session.
hope it will work.

Help!!! What's wrong with this code. JSP page can't retrieve properties.

I'v got a piece of code that was created to send some parameters to JSP page via POST method. But in server page I can't retrieve this parameters, please help me and try to find "main" bug in this code.
try {
URL url = new URL("http://localhost/index.jsp");
HttpURLConnection httpCon = (HttpURLConnection)url.openConnection();
httpCon.setRequestMethod( "POST" );
httpCon.setDoOutput( true );
String body = URLEncoder.encode("name=Oleg", "UTF-8");
httpCon.setRequestProperty( "Content-length", Integer.toString( outBody.length() ));
httpCon.setRequestProperty( "Content-type", "application/x-www-form-urlencoded" );
OutputStream os = httpCon.getOutputStream();
PrintWriter ow = new PrintWriter( os );
ow.print( body );
ow.flush();
ow.close();
} catch (....) {
}

Hi
You must not encode all the body just the values of the parameters.
You can do as following in order to send a post request with 2 parameters
String param1 = "Co & sons";
String param2 = "ltd.";
String encParam1 = URLEncoder.encode(param1,"UTF-8");
String encParam2 = URLEncoder.encode(param2,"UTF-8");
String body = "param1="+encParam1+"&param2="+encParam2;
OutputStream os = httpCon.getOutputStream();
PrintWriter ow = new PrintWriter( os );
ow.print( body );
ow.flush();
//read the response from the jsp
InputStream inS = httpCon.getInputStream();
byte[] buff = new byte[5000];
StringBuffer sbuff = new StringBuffer();
int nrBytes ;
while( (nrBytes = inS.read(buff, 0, 5000))!=-1) {
sbuff.append(new String(buff,0,nrBytes));
inS.close();
ow.close();
...This is the jsp page which gets the parameters
<%
     String param1 = request.getParameter("param1");
     param1 = new String(param1.getBytes(),"utf-8");
     String param2 = request.getParameter("param2");
     param2 = new String(param2.getBytes(),"utf-8");
%>I hope I helped you.

Tab Button in JSP page using Jdeveloper

Hi Guys
I have a basic question, In Jdeveloper I am creating a JSP page. I need to have Tab buttons in that page, but i am not able to locate the tab buttons, I wanted to know that do Jdeveloper provides the facility for tab buttons, if it does, where can i find the tab button on the Jdeveloper.
regards

Yes, it is possible. But you must use ADF Faces technology. There is component called ShowOneTab.
e.g.:
          <af:showOneTab position="above">
