[webdynpro] How to get the data from database and store in Excel sheet

Hi All-
I am developing an application in Webdynpro and I need to provide a URL ( link ) which if clicked , need to collect the data from Database ( SQL Server ) and puts in an Excel Sheet corresponding fields and opens the sheet.....
Please look into this issue and help me out......

"RUN-TIME ERROR '3078': The Microsoft Access database engine cannot find the input table or query 'name'. Make sure it exists and that its name is spelled correctly.

When I run the code below I get the following error:"RUN-TIME ERROR '3078': The Microsoft Access database engine cannot find the input table or query 'False'. Make sure it exists and that its name is spelled correctly. Note that I do not call
anything by the name of "false" anywhere in this code.
The subject code (the underscored line of code is highlighted in the debugger when the error occurs):
Option Compare Database
Private Sub JobAssign_Click()
MatLotListAvail_openform
End Sub
Function MatLotListAvail_openform()
Dim dbsAPIShopManager2010 As DAO.Database
Dim rstMaterialLotJobJoint As DAO.Recordset
Dim strSQL As String
Set dbsAPIShopManager2010 = CurrentDb
strSQL = "SELECT * FROM MaterialLotJobJoint WHERE JobID" = "tempvars!JobID" And "MatLotID" = "tempvars!MatLotID"
Set rstMaterialLotJobJoint = dbsAPIShopManager2010.OpenRecordset(strSQL, dbOpenDynaset)
If rstMaterialLotJobJoint.EOF Then
DoCmd.OpenForm "JobAssignMatConf", acNormal, "", "", acEdit, acNormal
Forms!JobAssignMatConf!PartapiIDVH = TempVars!PartapiID
Forms!JobAssignMatConf!JobapiIDVH = TempVars!JobapiID

Forms!JobAssignMatConf!MaterialLotIDVH = TempVars!MatLotID
Forms!JobAssignMatConf!Desc = TempVars!MatDesc
Forms!JobAssignMatConf!recdate = TempVars!recdate
DoCmd.Close acForm, "MaterialLotListAvailable"
Else: MsgBox "This material lot has already been assigned to this job."
DoCmd.Close acForm, "MaterialLotListAvailable"
End If
End Function

I think the SQL statement should be
strSQL = "SELECT * FROM MaterialLotJobJoint WHERE JobID=" & _
tempvars!JobID & " AND MatLotID=" & tempvars!MatLotID
This assumes thatJobID and MatLotID are number fields.

Pre-loading the Cache from Database during application start-up

We are using Spring, Hibernate, Oracle Coherence 3.5.2 Weblogic Webservices
Our requirement is to pre-load the cache during the application start-up most probably during Authentication/Authorization Service is invoked.
We plan to load the data for other services from database into Coherence cache so that whenever user access that particular service he ends up hitting the Cache instead of database.
We would greatly appreciate sample code snippets on how to write CacheInitializerBean with marker to demonstrate the state of cache.

Hi Rob,
Thanks for pointing to the article: Pre-Loading the Cache
In fact i already looked at that article before posting. It just mentions how to load the data from database into Cache.
What i am looking for is how to make this happen during application start-up. This is my first hurdle.
The second one is as mentioned in the article http://coherence.oracle.com/display/COH35UG/Pre-Loading+the+Cache
i wrote following code which never gets populated into cache. Not sure whats going wrong even though i see Hibernate loadAll() method loading all the objects in the console
public   void populateCache() throws SQLException
    Map<Long, Object> buffer = new HashMap<Long, Object>();
    int count = 0;
     List<Contract> contractList = this.getHibernateTemplate().loadAll(Contract.class);
     log.debug("contractList size="+contractList.size());
     for(Contract contract : contractList)
         Long key   = new Long(contract.getId());
         Object value = contract;
         buffer.put(key, value);
         // this loads 1000 items at a time into the cache
         if ((count++ % 1000) == 0)
              contractCache.putAll(buffer);
             buffer.clear();
     if (!buffer.isEmpty())
          contractCache.putAll(buffer);
    }We would greatly appreciate your time in helping us resolving two hurdle blocks.

Populating JSF ListBox from DataBase

Hi,
im new to JSF and i have a problem populating Listboxes with database values.
i have 3 listboxes and the 3 are populated from tables in my database.
I would like to filter the returned(from database) values in the 2nd listbox depending on the value selected in the 1st listox.
I dont know how to do this.
BTW i'm usis Ibatis Abator to map the database.
tnx

Here is what I think you are wanting to do:
1. Have the list box show values from a database table.
2. Have the user make selections. Should the user return to that page later in the session, have the previous selection still selected.
Normally, you would bind the listbox to the database table, as is shown in http://developers.sun.com/prodtech/javatools/jscreator/learning/tutorials/2/databoundcomponents.html. The only reason I can think of for not binding directly to the database table is if there is a possiblity that the database table can change (additions, updates, deletes) during the user's session.
Are you able to emulate the above tutorial using the Postgress database? It might be good to pinpoint whether the problem is with the Postgress driver or with the code you are writing.
By the way, if you use a data provider to access the database, as shown in the tutorial, here is how you iterate through the data
        try {
            myDataProvider.cursorFirst();
            do {
                [build your options list here]
            } while (myDataProvider.cursorNext());
        } catch (Exception ex) {
            error("put your message here" +
                    ex.getMessage());
            log("put your message here: " +
                    ex.getMessage(), ex);
        }You are correct to bind the selected property to a session bean property in order to perserve the user selecitons through the user's s session.

Pull the data from database.

Hi EveryBody,
I have a requirement in universe if the end user will select the date from (1/8/14 to 10/8/14) then pull the data from the database. but when the end user select the data more than 10 days(e.g 1/8/14 to 15/8/14 etc...) then no need to pull the data from database.
how will write the filter in the universe?
how will achieve this? please help me.
Thank you.

Hi ,
I am assuming you are giving prompt for start date and end date respectively start_date and end_date.
please see the below work around. (below is pseudo code)
1. create one dummy objects as
case when @prompt(end_date) - @prompt(start_date) <= 10 then = 1 end
Remember text used in dummy object should be same as you use it for you date prompts
2. pull this objects in where clause along with your date prompts as
dummy_object = 1
It will work as below :=
your report will be prompted for start_date and end_date .
Same values will be passed to dummy objects.
When dummy object will be executed , it will check for end_date-start_date <=10 or not.
If it is less then 10 then query will executed else it will come out as where clause is not satisfied.
Hope this answers your question :-).

Have a error in getting the values from database randomly

Hi to all
I am new member to this community and new to java programming, i am the one of them who got benefited through this site , with that hope i am asking u to clear my doubt.
Actually i want to get the data from database randomly, i dont have problem either in database connection and generating random number,its working fine. but when i have to get the data from database with generated random no using absolute function , i am getting an exception
eg : rs.absolute(2);
i could not move to the second row of my result set.
not only absolute function whatever the function i am using except next method, getting exception.
my code :
package practical;
import java.util.*;
import java.sql.*;
public class gen {
     Connection con;
     Statement s;
     ResultSet rs;
     public void get(int t)
          try
               rs.absolute(t);
               String question=rs.getString("question");
               System.out.println("Random question : "+question);
          catch(Exception e)
               System.out.println("get error");
     public void ran()
          Random r=new Random();
               for(int i=0;i<10;i++)
                    int j=r.nextInt(10);
                    System.out.println("random value : "+j);
                    if(j!=0)
                         try
                              get(j);
                         catch(Exception e)
                              System.out.println("ran error");
     public void connect()
          try

You mean when you click on the hyperlink you want that row to disappear from the page, but not delete the row from the database until a commit/submit button is pressed?
Personally, I think I'd prefer that you have a delete checkbox next to every row and NOT remove them from the display if I was a user. You give your users a chance to change their mind about their choice, and when they're done they can see exactly which rows will be deleted before they commit.
You know your problem, of course, so you might have a good reason for designing it this way. But I'd prefer not removing them from the display. JMO - MOD

Problem in printing the data from database when i print inside servlet

hi to all!
the objective of the code below is getting the data from database table and has to send that data to the web browser using out.println .note: out - PrintWriter object
In a getQuestion method, i am getting the data from database table and store it in String q and when i print the q within this method it is getting printed, but i got the null value when i printed the String q inside service method doPost. why..? its puzzling me.

Hi.
I want to draw bar, pi etc chart on the web page by getting the values from database oracle while implementing in jsp. kindly tell me how i can do this. Please write down the detailed code for it. Thankx.

Maybe you should try Cewolf which is a chart tag library based on JFreeChart to generate all kinds of charts in a JSP. See http://cewolf.sourceforge.net.
