Resultset Eventing
Hi all,
Could you please help me on the below scenario
I have a webdynpro application, which takes the Partner Number as input and gets the record ID from MDM. Now with the record ID i want to display that records in a standard Resultset iview.
How can this be achieved
Thanks
Suresh
Hi Suresh,
From the MDM Portal Content Development Guide, "Configuring Events on a Result Set iView":
You can configure EPCF and URL events using the Result Set iView Event Builder to accept requests from a Web Dynpro application.
Typically the MDM custom event listeners used for limiting a Result Set from the
custom application would be:
- getRecordByIds (EPCF) and GetRecordByIds (URL)
- updateSearch (EPCF) and SetSearchHandler (URL)
More details can be found in the guide.
hope this information helps,
Idan

MDM iView resultset problem and question about eventing
Hi experts,
I created a MDM iView resultset for my main table as search table (comparison is not supported). When I click on preview I get an empty table ("Found <Tablename>: 0 of 10", table contains 10 entries at the moment). I tried the same with a subtable and everything works fine (all entries have been in the preview table). Any ideas why I don't get a result?
My 2nd question: can I choose the parameter name in eventing (EPCF) on my own? So if I have Vendor_Id as field can I use vendorid as parameter name? Do I have to define anything in the listener iView (e.g. in detail iView for an event from resultset iView)? Maybe you have a useful tutorial link (please not SAP help section)?
Thanks for your answers.
Regards, bdIt is possible to retrieve the number of rows from a resultset --
Statement stmt= con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READONLY);
ResultSet rs= stmt.executeQuery("<your select query here>");
int totalRows;
if (rs.last()) // can it move to the last row?
totalRows= rs.getRow(); // get its row number
else
totalRows= 0; // no rows in the resultset
rs.first() // set the cursor back to the startNote that the resultset has to be scrollable (TYPE_SCROLL_INSENSITIVE).
kind regards,

ResultSet IView - eventing - hand over serveral records
Hi experts,
we use a standard resultset iview for connecting the repository with the EP - this works fine.
In case of "eventing": is there a possiblity to hand over more than one record via EPCF-eventing to another IView on the same page?
The target is an Visual Composer IView.
I would be glad, if there is an quick and easy possibility.
Thank you in advance for your answers.
KarinHi
I am trying to Export the data from Result Set Iview to Excel using a Java Web dynpro application.
I am passing an MDM search parameter but when I am trying to get the value ,its coming as null...
This is what I am doing

First i do the connect with mysql 4.1.11 and mysqlconnector 5.15..
url = "jdbc:mysql://" + server + "/dbname?user=user&password=pass"; Class.forName("org.gjt.mm.mysql.Driver").newInstance(); connect = DriverManager.getConnection(url); System.out.println(url); System.out.println("Connection successful");
then the i do a normal query
query = "SELECT * FROM betriebe where ergebnis is null and " + "((wieder_am is not null and wieder_am<now() and mitarbeiter=" + mitarbeiter +") or "+ "(mitarbeiter is null and wieder_am is null)) ORDER BY wieder_am desc, last_call limit 1;"; rS = state.executeQuery(query); rS.updateString("ID_NUMMER","blub"); // this is working at this point !!!! rS.updateInt("mitarbeiter",mitarbeiter); // this is working at this point !!!! rS.updateRow(); // this is working at this point !!!
Now my problem. I got a button on my GUI which has a Listener with this method
void cmd_nichterledigt_actionPerformed(ActionEvent e) { ResultSet tmp; try { SimpleDateFormat formatter = new SimpleDateFormat ("yyyy-MM-dd HH:mm:ss"); java.util.Date currentTime_1 = new java.util.Date(); String dateString = formatter.format(currentTime_1); System.out.println(dateString); rS.updateString("Memo", txt_memo.getText()); // Here the error happens ! rS.updateNull("ergebnis"); rS.updateNull("wieder_am"); rS.updateNull("mitarbeiter"); rS.updateInt("Wiedervorlage",0); rS.updateRow(); } } Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at com.mysql.jdbc.ResultSetImpl.findColumn(ResultSetImpl.java:1059) at com.mysql.jdbc.UpdatableResultSet.updateString(UpdatableResultSet.java:2487) at aokframe.modify(aokframe.java:995) at aokframe.cmd_nichterledigt_actionPerformed(aokframe.java:1889) at aokframe$1.actionPerformed(aokframe.java:421)
idk what i am doing wrong. My resultset must be closed somehow. But i coundn´t found my mistake. thx for any help.Hi,
You really shouldn't be mixing GUI and JDBC code.
I am guessing you have closed or re-executed the statement which generated the resultset.
I suggest reading about the Data Access Object (DAO) design pattern to limit the scope of your resultset objects and to separate JDBC code from the rest of your application.
Good luck! -

I'm getting desperate for a solution to this problem (as is the rest of the development team!).
Basically we've been trying to create a system that automatically assigns values (frequencies) to objects (nodes) based on a rule set. Each node contains a varying number of sub-objects (radios) and each radio needs one frequency. The database has been set up and has test data for our Solution class to go through. However, we've run into an odd problem where our ResultSets are suddenly closing.
The classes work like this:
Database Broker (handles connection to DB, as well as executeQuery and executeUpdate statements.)
Entry Broker (Holds all SQL statements for data retrieval in various methods. Each method contains an SQL statement to access data, and code to format that data into something useable by the main class.
Solution/Main class (Contains methods to use the data from the Entry Broker to test valid solutions. Certain rules apply to assigning frequencies to radios and this class ensures that the data applies to these rules before it writes the data back to the DB (via the EntryBroker).
The problem we continually run into is that whilst the ResultSets work fine in the Entry Broker, they are closed when they return to the Main class.
Here's the catch: It seems in most cases that only the FIRST ResultSet returned in each method is closed, the remaining ResultSets work fine. We worked around this problem by creating a 'dummy' ResultSet, which obtained data from the database which was never used (the project name). We put this in its own try catch bracket so it would not interrupt the project.
It worked fine for a few classes, but for others (notably the following one) it was ineffective. We've searched and searched but we cannot find anyone with a similar complaint (except a few people who have commented about ODBC version problems). Our ODBC version is 3.520.7713.0
Here's an example method from the Solution class (The entire class is over 1000 lines):
// Method to test Harmonic resonance for nodes within 10m
private boolean resonanceGlobal (boolean tstResonanceG, double txFreq, double rxFreq, int distance) {
System.out.println("Beginning global harmonic resonance check");
try {
// Getting Nodes
rsNode2 = eBroker.getNodes(projectNo);
// node loop
while (rsNode2.next()) {
System.out.println("602 Test Marker GHarm 1");
// get next node, store in nodeTemp
nodeTemp = rsNode2.getInt(1);
// System out to show which nodes will pass if statement
System.out.println(node + " compare to " + nodeTemp);
// avoid testing the same node against itself
if (nodeTemp != node) {
// distance check (only neccesary within 10m)
System.out.println("Test Marker Before Distance check");
distance = getDistance(node, nodeTemp, distance);
System.out.println("Test Marker After Distance check");
// distance check if statement
if (distance <= 10) {
System.out.println("618 Test Marker GHarm 2");
// get the radios of the node, foreign node
rsRadiosTemp = eBroker.getRadios(node);
rsDummy = eBroker.getDummy(projectNo);
rsRadios2 = eBroker.getRadios(nodeTemp);
// This dummy ResultSet normally fails so that
// the other ResultSets perform normally
try {
rsDummy.next();
} // end try

while (rsRadios2.next()) {
System.out.println("631 Test Marker GHarm 4");
// get next radio
radioTemp = rsRadios2.getInt(1);
// get the TX and RX of the radio
genericTX = getTX(radioTemp);
radioTempCon = getConnection(radioTemp);
genericRX = getTX(radioTempCon);
// calculate bounds for harmonics test
txLo = ((txFreq * 2) - genericTX) - 4; // 4Mhz below TX harmonics check
txHi = ((txFreq * 2) - genericTX) + 4; // 4Mhz above TX harmonics check
rxHi = ((rxFreq * 2) - genericRX) + 4; // 4Mhz above RX harmonics check
rxLo = ((rxFreq * 2) - genericRX) - 4; // 4Mhz below RX harmonics check
// checks TX and RX of foreign radio against TX, RX of current radio for separation
if ((txLo > genericTX && txHi < genericTX) || (rxLo > genericRX && rxHi < genericRX)) {
tstResonanceG = false;
break;
} //end if
else {
tstResonanceG = true;
} // end else
} //end foreign radio loop
// breaking out of loops for return
if (tstResonanceG == false)
break;
} // end radio loop
rsRadios2.close();
rsRadiosTemp.close();
} // end sameradio check
} // end distance check
}// end node loop
rsNode2.close();
} // end try
// Catch statement to stop from crashing in the
// event of an error during SQL statements.
catch (java.sql.SQLException resonanceGlobalException) {
// Prints out the error message produced
System.out.println(resonanceGlobalException);
} // end catch
// returns result
return tstResonanceG;

I'll leave it at that, since the program goes into an endless loop. The dummy Exceptions are our dummy resultsets crashing so the rest can survive. The other stuff is from different methods. You should be able to locate the logic of the program by following the System.outs
Test Markers with EB refer to the Entry Broker.
Any help would be appreciated since we cannot find any other way of running this class successfully.
SteveOk problem solved...
Basically I was calling one ResultSet after another. Thanks to the Database Broker's structure, this was killing the first ResultSet. I fixed up the loops so that ResultSets were only ever called just before they were needed, and it fixed the problem. The only other errors were simple logic faults which I drummed out in short order. Thanks for the help everyone! -
How to trap Submit button event in OAF
Hello,
I'm doing controller extension for create account button in Customer UI.
Issue: I'm not able to trap the table action to add extra validation logic.
I tried to use pageContext.getParameters("CreateButton") but it didn't work i.e. debug message was not printed written inside if statement.
Button Structure:
TableAction
Flowlayout
Submit button.
Code:
public void processFormRequest(OAPageContext pageContext,
OAWebBean webBean) {
//super.processFormRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
ArrayList exceptions = new ArrayList();
OAFlowLayoutBean oaflowlaybean =
(OAFlowLayoutBean)webBean.findChildRecursive("TableActionsRN");
OASubmitButtonBean vbuttonBean =
(OASubmitButtonBean)oaflowlaybean.findChildRecursive("CreateButton");
String buttonId = vbuttonBean.getID();
String buttonId12 = vbuttonBean.getName();
String asd=vbuttonBean.getEvent();
String s = pageContext.getParameter(EVENT_PARAM);
String s1 = pageContext.getParameter(vbuttonBean.getName());
if (s.equalsIgnoreCase("CreateAccount")) {
OAViewObject vo =
(OAViewObject)am.findViewObject("HzPuiAccountTableVO");
if (vo != null) {
pageContext.writeDiagnostics("Jai-1", "VO Found", 1);
OARow row = (OARow)vo.getCurrentRow();
if (row != null) {

10);
// super.initParametersPFR(pageContext,webBean);
vbuttonBean.setFireActionForSubmit(null, null, null, false);
super.processFormRequest(pageContext, webBean);
Please suggest the how to overcome with above mention issue.Hi Kiranmai,
You can capture the event of the radio button in the following way in oninputprocessing.
DATA: event TYPE REF TO if_htmlb_data,
radioButton_event TYPE REF TO CL_HTMLB_EVENT_RADIOBUTTON.
event = cl_htmlb_manager=>get_event( request ).
IF event IS NOT INITIAL AND event->event_name = htmlb_events=>radiobutton.
radioButton_event ?= event.
ENDIF.
you can get the attributes of clicked radio button in
event->event_class
event->event_id.
event->event_name
event->event_type
event->event_server_name
In layout define the radio button as
<htmlb:radioButtonGroup id = "test_id">
<htmlb:radioButton id = "id_red" text = "Red" onClick="myClick" />
<htmlb:radioButton id = "id_blue" text = "Blue" onClientClick="alert('blue clicked')"/>
<htmlb:radioButton id = "id_green" text = "Green" onClick="myClick" onClientClick="alert('green clicked')"/>
</htmlb:radioButtonGroup>
Hope this will solve your problem.

Need help Take out the null values from the ResultSet and Create a XML file
hi,
I wrote something which connects to Database and gets the ResultSet. From that ResultSet I am creating
a XML file. IN my program these are the main two classes Frame1 and ResultSetToXML. ResultSetToXML which
takes ResultSet & Boolean value in its constructor. I am passing the ResultSet and Boolean value
from Frame1 class. I am passing the boolean value to get the null values from the ResultSet and then add those
null values to XML File. When i run the program it works alright and adds the null and not null values to
the file. But when i pass the boolean value to take out the null values it would not take it out and adds
the null and not null values.
Please look at the code i am posing. I am showing step by step where its not adding the null values.
Any help is always appreciated.
Thanks in advance.

Closing the Statement returned from ResultSet.getStatement does not work
With the ORACLE JDBC driver, I have discovered (the hard way) that it is essential to explictly close a Statement object after use. (http://www.orafaq.com/node/758 was useful here).
Failure to do so leaves the Cursor open and eventually your application will fail with the ORA-01000 Too Many Cursors error.
That works well if your code still has access to the Statement object which it created when it has finished with the results from executing the Statement.
But, I've inherited some code where this is not the case. The results in the form of a ResultSet are passed through a few layers before it is eventually processed and can then be closed. The original Statement object is no longer available.
I thought then that the solution would be use the ResultSet.getStatement method and to close that Statement.
BUT that doesn't seem to work. The number of cursors continues to go up.
Any ideas, anyone?
(I'm using ojdbc6.jar and ORACLE 10g Express.)

When I execute the second query in the MYSQL Query Browser GUI, it works fine.
Thank you.ResultSet rs = s.executeQuery("SELECT E.date, FROM Event E");That's not valid SQL. There's a comma where there shouldn't be one.

How can i implement a mouse listener event on jtable cell?
I create JTable using a resultset,at the end of each row i add an image using JLabel(set imageicon of the JLabel).
i want to track the event when user click on that image.
What can i do for that?.
I tried by implementing mouseListener interface for the JLabel but it's not working properly.Hi,
Add MouseListener to the JTable.
when the user clicks on the table use the method
getValueAt( int selectedRow,int selectedColumn) to get the contents.
Object obj = getValueAt( int selectedRow,int selectedColumn) .
(If obj instance of JLabel)
do your functionality.
Hope this helps
Cheers :)

Problem with Calendar showing first day events
In my Java Bean, i have the following:
public ResultSet getEvents(GregorianCalendar start, GregorianCalendar end)
ResultSet rs = null;
java.sql.Timestamp startDate = new java.sql.Timestamp(start.getTimeInMillis());
java.sql.Timestamp endDate = new java.sql.Timestamp(end.getTimeInMillis());
try {
ps = con.prepareStatement("select * from events where startDate = '" + startDate + "' and startDate <= '" + endDate + "' order by startTime");
rs = ps.executeQuery();
catch (SQLException sqle) {}
return rs;
When ever my JSP page calls for this, it will not show the first day of the month Events. What am i doing wrong?I would guess that there's an SQLException being thrown, probably due to your database not liking the toString() output of Timestamp. Your code is eating SQLExceptions, though, so you'll never see the error.
You've gone to the trouble of creating Timestamp objects, use them appropriately:ps = con.prepareStatement("select * from events where startDate >= ? and startDate <= ? order by startTime");
ps.setTimestamp(1, startDate);
ps.setTimestamp(2, endDate);
rs = ps.executeQuery();

How to generate a report on 'Event Received' events for a resource objects
Hello,
I want to generate a report on all the recon events which are in 'Event Received' status, on a daily basis. Can you please let me know how to do this and what all tables are involved?
ThanksWell thats pretty simple. Actually there are multiple tables in OIM database responsible for holding reconciliation data but event information is stored in one table RCE. So there are two simple ways to do that as follows:
*1) Using OIM API ::*
There is an API exposed (*findReconciliationEvent()*) in the tcReconciliationOperationsIntf interface. You can just pass a HashMap with one filter parameter for ReconEvent status as Event Received. In addition to it this API also requires the StartDate and EndDate (You can give current date for both arguments). This will return you a ResultSet containing all the events which are in that particular state. Just iterate through the ResultSet for all the event information ad create your report.
*2) Using OIM database query::*
Just write an SQL query to run in the database schema. Let's assume you have written a scheduler for the same. This is the code for your class:
tcDataSet dsList = new tcDataSet();
String query = " select * from RCE where RCE_STATUS='Event Received' ";
log.debug(query);
try {
dsList.setQuery(getDataBase(), query);
dsList.executeQuery();
if (!dsList.isEmpty()){
log.debug("Total Rows Found:" + dsList.getTotalRowCount());
result = true;
for (int i = 0; i < dsList.getTotalRowCount(); i++) {
Write your custom logic here for generation of report
}else{
log.debug("No Events Found");
result = false;
} catch (tcDataSetException e) {
e.printStackTrace();
result = false;
So you can do it both ways.
Thanks

Why are all the events in the XML SAX parser not activated?
Hi everyone,
I have written a mini server that parses XML files into SQL queries.
Below is a segment of my code;
try {
Class.forName( JDBC_DRIVER );
myConnection = DriverManager.getConnection( DATABASE_URL, "username", "password");
EventXMLParser myEXP = new EventXMLParser(directory, myConnection);
File[] xmlFiles = directory.listFiles();
for (File xmlFile : xmlFiles) {
myEXP.XMLtoDB(xmlFile);
outWriter.println("File:" + xmlFile.getName() + " DONE");
} catch (SQLException e) {
System.err.println("SQLException for establishing connection");
e.printStackTrace();
} catch (ClassNotFoundException e) {
System.err.println("CLASS NOT FOUND EXCEPTION HERE");
e.printStackTrace();
} catch (Exception e) {
System.err.println(e);
e.printStackTrace();
finally {
outWriter.println("PARSING COMPLETED");
outWriter.close();
}Where the constructor EventXMLParser constructs the following:
public EventXMLParser(File path, Connection connection) {
super();
try {
this.XMLpath = path;
this.db_connection = connection;
this.xr = XMLReaderFactory.createXMLReader();
this.XMLSAXhandler = new DefaultHandler(); //create a new own handler
this.xr.setContentHandler(XMLSAXhandler);
this.xr.setErrorHandler(XMLSAXhandler);
//System.out.println("DEBUG: db_connection is " + db_connection.toString());
catch (Exception e) {
System.out.println("Constructor Error!");
e.printStackTrace();
}Below are all my helper methods within EventXMLParser.java
public void XMLtoDB(String XMLpath) throws Exception {
try {
//Input
System.out.println("XMLpath is : " + XMLpath);
/*FileReader r = new FileReader(XMLpath); debug

} My question is: I have taken my SQL query generated by toSQL() method in events and it worked.
Here is the funny thing:
Everything is correct syntax wise: No complaints what soever
The mysql part works: Tested separately.
So I tend to think that the problem lies within the SAX parser. I have written SAX2 parsers on this machine before and they have worked too. I tried inserting println statements all over startElement endElement etc etc only to find out that the SAX parser did not call any of the methods that I overided!! Why is that so?
Can you guys spot where my SAX parser fails?I see.
I try to correct this problem by removing super();
so right now my code looks like this:
static Event temp = new Event(0, 0, "null", "null", new Date(), 0, "null", 0);
static String CurrentElement = null;
static File XMLpath;
static Connection db_connection;
static XMLReader xr;
static DefaultHandler XMLSAXhandler;
//Constructor, Build the SAX Parser
public EventXMLParser(File path, Connection connection) {
try {
this.XMLpath = path;
this.db_connection = connection;
this.xr = XMLReaderFactory.createXMLReader();
this.XMLSAXhandler = new DefaultHandler(); //create a new own handler
this.xr.setContentHandler(XMLSAXhandler);
this.xr.setErrorHandler(XMLSAXhandler);
//System.out.println("DEBUG: db_connection is " + db_connection.toString());
catch (Exception e) {
System.out.println("Constructor Error!");
e.printStackTrace();
}This time, I created a new instance of default handler() which can be referenced by as the objects's XMLSAXhandler. However, that did not solve the problem, why does the problem still persist?
Right now, there is only one instance of a default handler created. So why does all my parsing event functions still get ignored?
