Getting the last action from a managed bean

Is it possible to get the last action that was submitted from within a backing bean.
I have an application that has a context specific menu at the top of the page. The context menu is generated using a backing bean which is called from a tiled jsp, called contextmenu.jsp.
The context menu backing bean needs to know what page it is on so that it can generate the correct menu, so is it possible to get hold of the last action submitted, or the current page from within the backing bean?
Any help would be much apprecieated.
Jamie Cash

Thanks for your help,
but ...
We will be developing over 200 jsps and don't want to load the development effort with a backing bean for each jsp.
The solution that I finally arrived at is using the following code in the menubean to get the view id, and make the decision based on that.
public NavigationMenuItem[] getContextMenu()
     //Get view id
          String viewId = FacesContext.getCurrentInstance().getViewRoot().getViewId();
          logger.debug("view id: " + viewId);
          //Menu
          NavigationMenuItem[] contextMenu = null;
          if(viewId.equals("/home.jsp"))
               .... Code to get context menu from Stateless Session bean
          //Return menu
          return contextMenu;
Regards

Read to get the last line from a File

Hi
I am sending in a clarification , hoping that I get an efficient solution from the group, should somebody have come across this scenario and implemented.
How to read or get the last line from a text file , which usually have a no of records, without actually reading or looping through all the lines
I know there is some solution with the RandomAccessFile, but given there can be some encoding issues or so.
Please let me know if somebody have implemented the same.
Thanks n advance

The character encoding could, indeed, be an issue especially with UTF-8. I think what I'd do is to create a byte array with the encoded, expected end of line sequence in it and work on the file in bytes. For example, seek to the last 100 bytes of the file, read those bytes and look for an EOL sequence backwards. If not found read the previous 100, 200, 400 bytes etc. until you do find an end of line. Then seek to after the EOL and read normally. Remember an EOL sequence might cross a boundary.
UTF-8 would be a problem, especially with a unix format file because you might mistake part of a multi-byte sequence for '\n'. To be reliable on UTF-8 you'd need to go back three characters looking for sequence start markers (has the previous character got the top bit set, or the one before that the first two bits set, or the one before that the top three bits). Or you could just react to an encoding exception and try another position.

Get the current value of a managed bean.

Hi guys
I have a register page which takes the Login ID and the password and retype password whose values are stored in the "Managed Beans" in registerServer.java.
I have a (PwdValidator.java) Custom validator for Re-type Password which validates itself against the password.
Now my problem is from the PwdValidator.java how can I access the value of the password which is stored in the managed bean in registerServer.java.
here is a copy of my faces-config.xml
     <managed-bean>
          <managed-bean-name>registerServer</managed-bean-name>
          <managed-bean-class>com.sun.registerServer</managed-bean-class>
          <managed-bean-scope>session</managed-bean-scope>
     </managed-bean>
Help is really appreciated,
Thanks,

Thanks for the reply but my question is how do I get
the password value from the managed bean
FacesContext context =
FacesContext.getCurrentInstance();
Application application = context.getApplication();
CountryValueObject registerServer =
(CountryValueObject)application.getVariableResolver().r
solveVariable(context, "registerServer");
String pwd = registerServer.password // So will this
give me the current value for that session.You didn't go far enough in replacing the example code . Try this:
FacesContext context = FacesContext.getCurrentInstance();
Application application = context.getApplication();
RegisterServer registerServer = (RegisterServer)application.getVariableResolver().resolveVariable(context, "registerServer");
String pwd = registerServer.password // So will this give me the current value for that session.

ADF Faces: How to get the ADF BindingContainer in a managed bean?

Hi,
I not sure how to get the BindingContainer instance from inside of a managed bean method. I have tried the following config, but it does not work in all situations.

</managed-bean>When an ActionListener- method of my ShowBooks bean is called the property bindingContainer is NULL!!
Is there a save way to get the BindingContainer in my bean??
Any hints are welcome.
Thanks,

Maybe I just need another pair of eyes but when I set this up as explained and watch it in the debugger my method public void setBindingContainer(DCBindingContainer bc) gets called but bc is null. Can anyone help?
Thanks
Backing Bean-
private DCBindingContainer bindingContainer;
public void setBindingContainer(DCBindingContainer bc) {
this.bindingContainer = bc;
public DCBindingContainer getBindings() {
return bindingContainer;
//I just threw this method on there in case I was missing something & I also
//tried using a getBindingContainer method above but that didn;t work.
public void setBindings(DCBindingContainer bindings) {

How to get the last record from the database

I am using MS Access database and Swings as GUI. I want to get the last record of a particular column from the table and store it as a varaible.

Hi
To get Last record of resultset, you have pass some parameter in constructor of CreateStatement.In such case Resultset should be scrollable and Readonly
Example
objStatement=objCon.createStatement ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
mwwResultSet=cwwStatement.executeQuery(mwwSqlQuery);
while(mwwResultSet.next())
if(mwwResultSet.isLast())
//Fetch the required column record.
String abc=mwwResultSet.getString(1);
I think this will work. Try it.

Get the last query from the current user

Is there a way to get the last query of the current user, so every query could be log with a database trigger?
Let's just say I execute:
DELETE xxxx;
I tried :
SELECT T.SQL_TEXT FROM V$SQLAREA T where ADDRESS=(SELECT prev_sql_addr FROM v$session where audsid=userenv('sessionid'));
But the result of this query is :
'SELECT T.SQL_TEXT FROM V$SQLAREA T where ADDRESS=(SELECT prev_sql_addr FROM v$session where audsid=userenv('sessionid'))'
Is there a way to execute a query that would return :
'DELETE xxxx'
Thanks

You could join SQL_ADDR in v$session with ADDRESS in v$sqlarea to determine the SID that executed that SQL statement last. Note that PREV_SQL_ADDR in v$session will indicate the previous SQL he executed. Though you would have to look at these tables very often to get all SQL statements issued. One note here, I think if a different user ran the SAME SQL with just bind var differences the SQL_AREA will only show the last userâs information that executed it.
BTW - it will show deletes also...

Trying to get the last row from a resultset

Hi,
I'm trying to do a query to postgreSQL and have it return the last updated value, (last row).
My prepared statement is returning the correct results, but i'm having a problem getting the latest value.
I'm using a comboBox to drive a textfield, to load the last entered values in depending on which item in the comboBox is selected.
I've tried a variety of things and most seem to return the first row, not showing the updated values.
Or, if it does work, it takes to long to load, and i get an error.
here is the working code;
Object m = machCBX.getSelectedItem():
try { PreparedStatment last = conn.prepareStatement("SELECT part, count FROM production WHERE machine = ?",
ResultSet.TYPE_SCROLL_INSENSITIVE, //tried both INSENSITIVE and SENSITIVE
ResultSet.CONCUR_READ_ONLY);
last.setString(1, String.valueOf(m));
rs. = last.executeQuery();
if(rs.isAfterLast) == false ) {
rs.afterLast();
while(rs.previous()) {
String p = rs.getString("part");
int c = rs.getInt("count");
partJTX.setText(p);
countJTX.setText(c);
}this grabs values, but they are not the last entered values.
Now if i try to use rs.last() it returns the value i'm looking for but takes to long, and i get:
Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: Java heap space I also know using ra.last() isn't the best way to go.
I'm just wondering if there is another way other than getting into vectors and row count? or am i better off to go with the later?
thanks
-PD

OK, you've got a major misunderstanding...
The relational database model is built on the storage of sets - UNORDERED sets. In other words, when you hand a database a SELECT statement without an ORDER BY clause, the database is free to return the results in any order.
Now it so happens that most databases will happen to return data retrieved by an unordered SELECT, at least for a while, in the same order that it was inserted, especially if no UPDATE or DELETE activity has occured, and no database maintenance has occured. However, eventually most tables have some operation that creates a "space" in the underlying storage, or causes a row to expand and have to be moved or extended, or something. Then the database will start returning unordered results in a different order. If you (or other people) never ever ever UPDATE or DELETE a table, then on some databases the data might well come out in insertion order for a very very long time; given human nature and the way projects tend to work, relying on that is a sucker's bet, IMHO.
In other words, if you want the "most recent" something, you need to store a timestamp with your data. (With some databases, you might be able to take advantage of some non-standard feature to get "last updates" or "row change timestamps", but I know of no such for Postgres.
While this won't solve your major problem, above, your issue with rs.last is probably occuring because Postgres by default will prefetch your entire ResultSet. Use Statement.setFetchSize() to change that (PreparedStatement inherits the method, of course).

Getting the last record from the internal table

When we use a READ statement it always picks up the first record which fulfill its condition but in my case I want to pick up the last record that fulfills it condition
I have a internal table like
id     type
N1      A
N1      T
N1      A
N1      6 ----> LAST RECORD
my code is
read table itab wIth key id = netobjid.
for eg if netobjid = N1 , then I want to read the last record that corresponds to N1 ie ID N1 TYPE - 6...
How to do that?

HI
actually i have done same requirement like this ...
Take one count variable into your internal table ..you pass the number of records into cont variable for every time u enter the loop .
Sort the internal table with count variable descending . ( AS we cant sort the internal table with sy-tabix)
Then use read statement with sy-index = 1 .
USe below logic ,............
data : count type i value '0'.
LOOP at int .
count = count + 1 .
endloop.
sort int count descending .
read int with index = 1 .

How to get iterator values from a managed bean ?

Due to a bug in selectOneChoice i'm not able to get the label list i want to display directly from an iterator when the value binding is a managed bean.
To solve the problem i would like to create a managed bean that contains that list and use it as the selectItems to display.
I would like that the values in that managed bean loaded from the a data control iterator.
My question is :
1) is it possible to access the iterator values from a managed bean, i mean without any reference to a page definition
2) how to do ? is it documented somewhere ? any example ?

Howto: Iterate ADF BC from a managed bean from the View?

Hi Everyone,
I've been trying to iterate a BC ADF object from a managed bean from the view layer. Here is what I have done so far, but I don't seem to get any records:
In faces-config.xml, I am passing in the BindingContext to the managed bean. (This is a session scoped bean).
<managed-property>
      <property-name>bindings</property-name>
      <property-class>oracle.adf.model.BindingContext</property-class>
      <value>#{data}</value>
    </managed-property>In the testPageDef.xml I have the executables and bindings setup:
<executables>
    <iterator id="TestRO1Iterator" RangeSize="-1" Binds="TestRO1"
              DataControl="ApplicationControlDataControl"/>
</executables>
<bindings>
    <table id="TestRO1" IterBinding="TestRO1Iterator">
      <AttrNames>
        <Item Value="C1"/>
        <Item Value="C2"/>
      </AttrNames>
    </table>
</bindings>In my managed bean, in addition to the accessors for the bindingContext of bindings, I have:
             BindingContainer bc = getBindings().findBindingContainer("testPageDef");
             ControlBinding cb = bc.getControlBinding("TestRO1");
             RangeBinding rb = (RangeBinding)cb;
             List testList = rb.getRangeSet();
             Iterator testIter = testList.iterator();
             int testCount = testList.size();
             while (testIter.hasNext()) {
               Map attrs = (Map)testIter.next();
               System.out.println(attrs.get("C1")+","+attrs.get("C2"));
               //Do some fancy stuff here with the values.
             }However, my testList.size() always returns 0.
Is this the right method to programatically access the data from the view layer from a managed bean, or have I missed something completely? Are there any working samples that I could take a look at?

If it hadn't found the row, I expect you would have got an Exception

How to get the last value edited by users from JTable?

Hi.
I have a JDialog that includes an editable JTable. This table is used to set up field caption and font for a report program. I found only when cursor is moved to another cell, the value in current cell being edited will be transferred to Table Model. So if the user don�t move cursor to another cell after editing the value of a cell but click OK button directly, Table Model cannot get the last value edited by the user, I wonder if there is a way to fire JTable to transfer the value being edited to Table model.
By the way, I found if the TableCellEditor is using JCheckBox or JComboBox instead of JTextField, there is no this problem.
Thank you for any reply.

I guess you can make use of the following methods on your table model to inform it make it getValueAt bcos table data has changed.
fireTableCellUpdated
Notifies all listeners that the value of the cell at [row, column] has been updated.
fireTableChanged
Forwards the given notification event to all TableModelListeners that registered themselves as listeners for this table model.
fireTableDataChanged
Notifies all listeners that all cell values in the table's rows may have changed. The number of rows may also have changed and the JTable should redraw the table from scratch. The structure of the table (as in the order of the columns) is assumed to be the same.
But when to call these methods??
-- When OK button is pressed, do this as the first thing!!
OR
-- Call this on every key event!!

How to get the last inserted record from a table ?

:-) Hiee E'body
I work on Oracle 8i and need to get the last
record inserted in a table.
I have tried using rownum and rowid pseudo-columns
but that doesn't work.
Can you please help me out ?

I'm not sure about 8i features.
I assume here that you don't have 'Date-Time' stamp columns on the table which is the easiest way to determine the last inserted row in the table.
If not try the following :-
select address, piece, SQL_TEXT
from V$SQLTEXT
where upper(sql_text) like '%INSERT INTO TABLE_NAME%'
Substiute the TABLE_NAME with the name of the actual table.
Have fun.

How can I get the last 18 numbers from this string

Hi,
I'm querying this field from a table. How can I only get the last 18 numbers:
The numbers look like this:
500000000818118

If it is always the last 18 numbers just use the Right() function. Examples:
Right("500000000818118", 18)
or
<cfset mystring = "500000000818118">
<cfset mynewstring = Right(mystring, 18)>
or
#Right(yourquerycolumn, 18)#
etc.
Edit:
Well I just noticed that your example string is only 15 characters long. Perhaps I mis-understood your question?
