How to iterate over the attributes of a single entity?

I am working on a logical model transformation script. I take a list of all entities:
     var entities = model.getEntitySet().toArray();
iterate over the entities:
     for (var e = 0; e < entities.length; e++) {
        var entity = entities[e];
and try to get a list of all attributes for the current entity:
        var attributes = entity.getAttributeSet().toArray();
After that I try to iterate over the attributes:
        for (var a = 0; a < attributes.length; a++) {
            var attribute = attributes[a];
While iterating over the attributes I realized that the list is always the same. I get always a list of all attributes probably of the whole model even for entities without any attribute.
How can I get a list of the attributes for one single entity?

Hi,
Use entity.getAttributes()

JSF How to iterate over the list of a panelForm's child elements.

Hi all
My users have asked me to create a "clear all" button that initializes all input values of a search form's fields to null.
To do this I created a managed bean and added the following code
public String ClearFieldsBtn_action()
String[] fieldIDs = {
"Material",
"Description",
"Length",
"Width",
"Thickness",
for (int i = 0; i < fieldIDs.length; i++ )
try {
AttributeBinding attr = (AttributeBinding)getBindings().getControlBinding(fieldIDs);
attr.setInputValue( null);
} catch (Exception e) {
System.out.println(e.toString());
return null;
I wonder if there any other more elegant way to iterate over the fields contained inside the JSF panelForm that contains all these "Material", "Description", etc fields and thus be able to easily transport the same functionality in more that one page?
Thanks in advance
Thanassis

Thanassis,
I use some code like this (where "target" is a variable in the managed bean representing the parent component - the panelForm in your case):
    List children;
    int i, cnt;
    children = target.getChildren();
    cnt = target.getChildCount();
    for (i=0; i< cnt; i++)
      // do whatever you need here, such as clearing fields
    }This doesn't operate on the model, just on the UI components themselves. I do use something like this in a superclass backing bean for when I need to iterate over a bunch of UI components.

How can I iterate over the columns of a REF CURSOR?

I have the following situation:
DECLARE
   text   VARCHAR2 (100) := '';
   TYPE gen_cursor is ref cursor;
   c_gen gen_cursor;
   CURSOR c_tmp
   IS
        SELECT   *
          FROM   CROSS_TBL
      ORDER BY   sn;
BEGIN
   FOR tmp IN c_tmp
   LOOP
      text := 'select * from ' || tmp.table_name || ' where seqnum = ' || tmp.sn;
      OPEN c_gen FOR text;
      -- here I want to iterate over the columns of c_gen
      -- c_gen will have different number of columns every time,
      --        because we select from a different table
      -- I have more than 500 tables, so I cannot define strong REF CURSOR types!
      -- I need something like
      l := c_gen.columns.length;
      for c in c_gen.columns[1]..c_gen.columns[l]
      LOOP
          -- do something with the column value
      END LOOP;
   END LOOP;
END;As you can see from the comments in the code, I couln'd find any examples on the internet with weak REF CURSORS and selecting from many tables.
What I found was:
CREATE PACKAGE admin_data AS
   TYPE gencurtyp IS REF CURSOR;
   PROCEDURE open_cv (generic_cv IN OUT gencurtyp, choice INT);
END admin_data;
CREATE PACKAGE BODY admin_data AS
   PROCEDURE open_cv (generic_cv IN OUT gencurtyp, choice INT) IS
   BEGIN
      IF choice = 1 THEN
         OPEN generic_cv FOR SELECT * FROM employees;
      ELSIF choice = 2 THEN
         OPEN generic_cv FOR SELECT * FROM departments;
      ELSIF choice = 3 THEN
         OPEN generic_cv FOR SELECT * FROM jobs;
      END IF;
   END;
END admin_data;
/But they have only 3 tables here and I have like 500. What can I do here?
Thanks in advance for any help!

The issue here is that you don't know your columns at design time (which is generally considered bad design practice anyway).
In 10g or before, you would have to use the DBMS_SQL package to be able to iterate over each of the columns that are parsed from the query... e.g.
CREATE OR REPLACE PROCEDURE run_query(p_sql IN VARCHAR2) IS
v_v_val     VARCHAR2(4000);
v_n_val     NUMBER;
v_d_val     DATE;
v_ret       NUMBER;
c           NUMBER;
d           NUMBER;
col_cnt     INTEGER;
f           BOOLEAN;
rec_tab     DBMS_SQL.DESC_TAB;
col_num     NUMBER;
v_rowcount NUMBER := 0;
BEGIN
-- create a cursor
c := DBMS_SQL.OPEN_CURSOR;
-- parse the SQL statement into the cursor
DBMS_SQL.PARSE(c, p_sql, DBMS_SQL.NATIVE);
-- execute the cursor
d := DBMS_SQL.EXECUTE(c);
-- Describe the columns returned by the SQL statement
DBMS_SQL.DESCRIBE_COLUMNS(c, col_cnt, rec_tab);
-- Bind local return variables to the various columns based on their types
FOR j in 1..col_cnt
LOOP
    CASE rec_tab(j).col_type
      WHEN 1 THEN DBMS_SQL.DEFINE_COLUMN(c,j,v_v_val,2000); -- Varchar2
      WHEN 2 THEN DBMS_SQL.DEFINE_COLUMN(c,j,v_n_val);      -- Number
      WHEN 12 THEN DBMS_SQL.DEFINE_COLUMN(c,j,v_d_val);     -- Date
    ELSE
      DBMS_SQL.DEFINE_COLUMN(c,j,v_v_val,2000); -- Any other type return as varchar2
    END CASE;
END LOOP;
-- Display what columns are being returned...
DBMS_OUTPUT.PUT_LINE('-- Columns --');

    -- Exit when no more rows
    EXIT WHEN v_ret = 0;
    v_rowcount := v_rowcount + 1;
    DBMS_OUTPUT.PUT_LINE('Row: '||v_rowcount);
    DBMS_OUTPUT.PUT_LINE('--------------');
    -- Fetch the value of each column from the row
    FOR j in 1..col_cnt
    LOOP

Session Problems: "Don't know how to iterate over supplied "items""

Hi, I am developing my first application using Struts and JSP. The Action Form loads an object called reportGrid into session and I am trying to display it on a JSP page. Displaying simple variables works fine, but I can display an object. The error I receive is: Don't know how to iterate over supplied "items"
My object is made up of a group of ArrayLists looks similar to this this:
        private List affiliateID;
     private List affiliateName;
     private List product1;
     private List product2;
     //etc for about 10 listsThe object is filled with data from a result set and placed into session like:
     HttpSession session = request.getSession();
     session.setAttribute("grid", reportGrid);The goal is to display each list in its own column in a HTML table.
<table>
<tr>
<c:forEach var="affiliateName" items="${grid}">
          <td>
               <c:out value="${affiliateName}" />
          </td>
     </c:forEach>
     <c:forEach var="product1" items="${grid}">
          <td>
               <c:out value="${product1}" />
          </td>
     </c:forEach>
     <c:forEach var="product2" items="${grid}">
          <td>
               <c:out value="${product2}" />
          </td>
     </c:forEach>
</tr>
</table>I'm sure this has been asked before but I could not find any examples in the forums. I can place an ArrayList directly into session and iterate through using <c:forEach tags but when I try to do the same with an object it gives me the error " Don't know how to iterate over supplied "items" ".
Does anyone have any examples of pulling and displaying an object in session which contains ArrayLists? I have been stuck on this same error for a while and any help will be greatly apreciated.
James.

thank you!

so you suggest the method oneConsidering that I said exactly the opposite, it is a mystery to me how you could possibly have drawn that conclusion. I don't intend to keep repeating myself or to keep clarifying statements that are already perfectly clear. If you don't understand something, please say so. But don't put words into my mouth thanks.
that means all logical will be handle on bean and not servlet is needed?Once again I have no idea what you mean by this question.
what is the role for the servlet in MVC?And I have no idea what you mean by this question either, or how it relates to this thread. A JSP is a servlet in case you didn't know.

only one problem is that Manager column is generating this outcome rather showing exact name of the line Manager .
CN=Mr XYZ ,OU=Users,OU=IT,OU=Departments,OU=Company ,DC=organization,DC=com,DC=tk

In Jsp TagLib how can I get the Attribute value (like JavaBean) in jsp

TagLib how can I get the Attribute value (like JavaBean) in jsp .
I do this thing.
public void setPageContext(PageContext p) {
          pc = p;
pc.setAttribute("id", new String("1") );
          pc.setAttribute("first_name",new String("Siddharth")); //,pc.SESSION_SCOPE);
          pc.setAttribute("last_name", new String("singh"));
but in Jsp
<td>
<%=pageContext.getAttribute("first_name"); %>
cause null is returing.
Pls HELP me
with regards
Siddharth Singh

First, there is no need to pass in the page context to the tag. It already is present. How you get to it depends on what type of tag:
Using [url http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/jsp/tagext/SimpleTagSupport.html]SimpleTagSupport
public class MyTag extends SimpleTagSupport
public void doTag()
    PageContext pc = (PageContext)getJspContext();
    pc.setAttribute("first_name", "Siddharth");
    pc.setAttribute("last_name", "Singh");
    pc.setAttribute("id", "1");
}Using [url http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/jsp/tagext/TagSupport.html]TagSupport or it's subclass [url http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/jsp/tagext/BodyTagSupport.html]BodyTagSupport the page context is aleady declared as an implicit object:
public class MyTag extends TagSupport
public void doStartTag()
    pageContext.setAttribute("first_name", "Siddharth");
    pageContext.setAttribute("last_name", "Singh");
    pageContext.setAttribute("id", "1");
}In each case, this sort of thing should work:
<mytags:MyTag />
<%= pageContext.getAttribute("first_name") %>I

How and When Does the attribute VI_ATTR_VXI_TRIG_STATUS get initialized

How and When Does the attribute VI_ATTR_VXI_TRIG_STATUS get initialized. Do the actual trigger lines get measured or does the attribute get initialized to a default value when the vxi resource manager is executed?

Hey whl6868,
According to page 157 (or 3-135) of the manual (http://www.ni.com/pdf/manuals/370132c.pdf), there is no default value for VI_ATTR_VXI_TRIG_STATUS. If Resman is returning valid values for it, then it must be actually reading the lines. Else, I would only expect it to return valid values when you actually call the function yourself.

How can I convert the attribut lastLogon ...

Hi,
How can I convert the attribut lastLogon on an Active
Directory Microsoft?
Attributes ar = ctx.getAttributes(dn, attrs);
if (ar != null) {
for (int i=0; i<attrs.length; i++) {
Attribute attr = ar.get(attrs);
if (attr != null) {
String values="";
for ( Enumeration vals=attr.getAll();
vals.hasMoreElements(); ) {
values += vals.nextElement();
if ( vals.hasMoreElements() )
values += "\t";
entry += SRV.SEPARATOR + values;
When I take the value of the restrained attribut of the
enumeration how I make convert it for example in a date ?
I am using Windows2000 Advanced server.
An example of lastLogon attribue is "126949578544450976".
Any help is greatly appreciated.

How do I change the volume for a single midi instrument in GarageBand 10? Every time I move the volume, it moves back!

Every time I move the volume, it moves back!
Check, if you have a volume automation set on the software instrument track.
If the track volume automation curve is enabled, the volume slider for the track will move with the automation curve.
Click the automation curves disclosure triangle in the track header and disable the volume automation.

How can you get the schedule of a single reoccurring job with Restart ability in Redwood to pause when it has failed...?

We need the Request Restart ability when scheduling a single reoccurring job in Redwood. Most of our jobs are scheduled in CHAINs which offers the Final Status Handler on Step level, and the schedule is "paused" when a job in the CHAIN has failed ( the next instance does not populate until the OP MSG has been Replied to) , and once the OPERATOR message is replied to, the CHAIN can resume running again ( desired ) . But we need this same ability when scheduling a single job not in a CHAIN. In our testing, we set up a job with Request Restart chosen on the Error , Killed and Unknown selections on the Restart Behavior Tab. But we found when a job is scheduled say once a day at 8AM, and when it fails, an OPERATOR msg appears allowing a Restart choice ( desired), but the next day's schedule also populates ( undesired) and we do NOT want the schedule to continue on yet because we need a chance to fix the error before the next insance runs for business reasons. So how can you get the schedule of a single reoccurring job with Restart ability in Redwood to pause when it has failed...?

Hello Fran,
You can wrap the job chain in a master job chain in the first step and set the final status handler there.
You can also set the Restart Behavior to 'Stop Submit Frame', in that case you will have to resubmit the job once you are finished troubleshooting.

How do I change the background of a single cell or a row in a table?

How do I change the background of a single cell or a row in a
table? I doesn't seem to be letting me do that.

Are you using the latest DW? If so, then it isn't letting you
because
bgcolor is deprecated and shouldn't be used.
The correct way is to use css to define the background of a
cell
CSS:
.blackcell {background-color: black;}
HTML:
<td class="blackcell">whatever in the cell</td>

How can I access the Attribute Values from the Search Region

Hi all,
I have a table which contains Company id, department id, and PositonId. For a particular Company and Department there may be multiple records.
I have to pupulate a table which contains the position and other details that comes under a particular Department and Position based on the selection in the Three comboBoxes.
Also I have to populate a select many Shuttle to add new postions and records under a particular Department.
I created a query panel *(Search Region)* for the serch and a table to display the data. That is working fine.
Now the issue is I am using a view criteria to populate the shuttle with two bind variables ie, DepartmentId and CompanyId.
If the serach will return a resuktant set in the table it will also pupulate the correct records, otherwise ie, if the if the serch result is empty the corresponding iterator and the attribute is setting as null.
SO I want to access the attribute values from the Search Region itsef to populate the shuttle.
I don't know how can I access the data from the Search Region.
Please Help.
Regards,
Ranjith

you could access the parameters entered in search region by the user as follows:
You can get handle to the value entered by the user using queryListener method in af:query.
You can intercept the values entered as described
public void onQueryList(QueryEvent queryEvent) {
// The generated QueryListener replaced by this method
//#{bindings.ImplicitViewCriteriaQuery.processQuery}
QueryDescriptor qdes = queryEvent.getDescriptor();
//get the name of the QueryCriteria
System.out.println("NAME "+qdes.getName());
List<Criterion> searchList = qdes.getConjunctionCriterion().getCriterionList();
for ( Criterion c : searchList) {
if (c instanceof AttributeCriterion ) {
AttributeCriterion a = (AttributeCriterion) c;
a.getValues();
for ( Object o : a.getValues()){
System.out.println(o.toString());
//call default Query Event
invokeQueryEventMethodExpression("#{bindings.ImplicitViewCriteriaQuery.processQuery}",queryEvent);
public void onQueryTable(QueryEvent queryEvent) {
// The generated QueryListener replaced by this method
//#{bindings.ImplicitViewCriteriaQuery.processQuery}
QueryDescriptor qdes = queryEvent.getDescriptor();
//get the name of the QueryCriteria
System.out.println("NAME "+qdes.getName());
