PreparedStatement and Date inputs

Hello,
Trying to recover table rows with date columns inside from mysql, I do the following without any success :
String sqlFilter = "SELECT * FROM mytable WHERE startdate>=\"?\" AND startDate<\"?\"";
PreparedStatement statement = myConnection.prepareStatement( sqlFilter);
java.util.Date myUtilDate = ....;
java.sql.Date mySQLDate = new java.sql.Date( myUtilDate.getTime() );
statement.setDate(1, mySQLDate);
ResultSet rSet = statement.executeQuery( sqlFilter);The resultset never finds anything. What is wrong in this code?
Thanks in advance,
Olivier

Unless I am missing something that code is going to throw an exception.
Or the correct code was not posted.
There are either two bind variables or there are none - which depends on how MySQL treats a double quote (and also how the database is set up.)
And there is only one set statement.
With no bind variables the set statment will fail.
With two bind variables the query will fail because one bind variable is not set.
So I would guess that you have a catch block, also not posted, and you are ignoring the exceptions from it.

Restrict Data Input in an Input Schedule for a particular number of days in a Month

Hi All,
I want to restrict data save in Input Schedule for any particular number of days in a month. BRAD will select number of days for the that particular month and data input for that duration should be disabled.
Duration will be dynamic and will be decided by BRAD.
Basically this is a requirement of BPF, but I have thought of doing in this manner.
Regards,
Mayank

Hi Vadim
I saw your this solution:
Dim epm As New FPMXLClient.EPMAddInAutomation
Dim blnMySave As Boolean
Public Function BEFORE_SAVE() As Boolean
If blnMySave Then
    BEFORE_SAVE = True
Else
    MsgBox "Please use button on the worksheet!"
    BEFORE_SAVE = False
End If
End Function
It seems as if this may help me, but can you please guide me how to trigger this function for a change of value in any particular cell, in an input form.

Repeating User input (such as name and date) on each page automatically

Is there a way of having the information provided by the user on one page, such as name and date, automatically repeated on separate pages (perhaps as a header/footer.) The input would be via Reader only.
I have an application form of four pages, after the first page there is no direct unique evidence linking the remaining pages to the first.
Basically I want each page when printed to have an identifier, so that in the event of the pages getting mixed up, they can be put back together.
Any advice gratefully accepted

Hi,
you can sole your problem with many way...
- You can use Global binding, so user nter data one time and every field with the same name automaticaly get the same value.
- You can use some Javascritp to obtain similar effects (more complicated but more fexible):
Create a Js Object (name it Global for Example).
Create some variables, i.e.: var field1;
Place one field in master pages and in their initialize event use the statement below:
Global.field1 = this;
In this way you obtayn a refernce that you can use everywhere in your form.
For example you can write: Global.field1.rawValue = "Hello word";
I hope this helps :-)
Bye.

Problem to calculate the coherence (using NetworkFunction-VI) with only 1 row of data for each, the stimulus and response input

Hello,
I am trying to calculate the coherence of a stimulus and response
signal using the Network Functions (avg) VI's. The problem is that I
always get a coherence of "1" at all frequencies. This problem is
already known (see KnowledgeBase document: Why is the Network Functions (avg) VI's Coherence Function Output "1"?).
My trouble is that the described solution (-> the stimulus and response input matrices need to have at least two rows to get non-unity coherence values) doesn't help me much, because I only have one array of stimulus data and one array of response values.
Thus, how can I fullfil the 'coherence-criteria' to input at least two rows of data each when I just have one row of data each?
Any hint or idea is very much appreciated. Thanks!

With this weird board layout, I'm not sure whether you were asking me, but, on the assumption that you were, here goes:
I found no need to use the cross-power spectrum and power spectrum blocks
1... I was looking for speed.
2... I already had the component spectral data there, for other purposes. From that, it's nothing but addition and multiplication.
3... The "easy" VIs, assume a time wave input, as I recall. Which means they would take the same spectrum of the same timewave several times, where I only do it once.
I have attached PNGs of my code.
The PROCESS CHANNEL vi accepts the time wave and:
1... Removes DC value.
2... Integrates (optional, used for certain sensors).
3... Windows (Hanning, etc. - optional)
4... Finds spectrum.
5... Removes spectral mirrors.
6... Scales into Eng. units.
7... From there, you COULD use COMPLEX-TO-POLAR, but I don't care about the phase data, and I need the MAG^2 data anyway, so I rolled my own COMPLEX-TO-MAG code.
The above is done on each channel. The PROCESS DATA vi calls the above with data for each channel. The 1st channel in the list is required to be the reference (stimulus) channel.
After looping over each channel, we have the Sxx, Syy, and Sxy terms. This code contains some averaging and peak-picking stuff that's not relevant.
From there, it's straightforward to ger XFER = Sxy/Sxx and COHERENCE = |Sxy|^2 / (Sxx * Syy)
Note that it uses the MAGNITUDE SQUARED of Sxy. Again, if you use the "easy" stuff, it will do a square-root operation that you just have to reverse - it is obtained faster by the sum of the squares of the real and imag parts.
Hope this helps.

I have a 2007 iMac connected via WiFi. It has been working fine until I turned it on after a recent vacation. Network Preferences indicates that it is correctly connected to my WiFI system but the data input and output rate is virtually zero. I know that the WiFI signal is reaching the iMac since both my iPhone and iPad are working perfectly at that location. I have rebooted the router and the iMac to no avail. Any suggestions would be greatly appreciated. Thank you very much. Geoff

Managed Beans and Data Access Object

I have a question / need help understanding how to configure backing bean and model objects so that memory and object creation/deletion is done as efficiently as possible.
1. I have a .jsf page with a form and a commandbutton that submits the form inputs to a backing bean (enrollispbean is backing bean)
<h:commandButton value="Enter" action="#{enrollispbean.insert}"/>
2. The backing bean is used for form handling - the insert() method is used to read the data fields from the form and create a SQL string that will be submitted to a model object, DbInsert, that is used as a generic data access object that connects to the database and insert the SQL string:
public class EnrollIspBean {
private String beanvar1="";
private String beanvar2= "";
// DbInsert is data access object
private DbInsert dbinsert = new DbInsert();
public String insert (){
String sqlstmt;
sqlstmt = "INSERT INTO ispmain VALUES(beanvar1, beanvar2,..)"
dbinsert.insert(sqlstmt);
return "success"; }
3. DbInsert is the data access object that contains a method, insert(), that accepts a sql string to insert into the database. This method contains the code to obtain a connection from the database connection pool and then execute the sql statement (note: error checking code not shown):
public class DbInsert {
public void insert(String sqlstmt) throws SQLException {
Connection conn = null;
GetDBConnection getdbconnection = new GetDBConnection();
PreparedStatement stmt = null;
conn = getdbconnection.getdbconn();
stmt = conn.prepareStatement(sqlstmt);
stmt.executeUpdate();
stmt.close();
conn.close();
return;
Where I need help understanding is how to set up the scope for the managed beans and data access object. Currently, I have the backing bean within the session scope (using the facesconfig.xml file). My main question is how to set up the scope for the Data Access Object - currently I do not have it as a managed bean within facesconfig.xml. Instead I am creating a new instance within the backing bean:
private DbInsert dbinsert = new DbInsert();
Is this the best way to do this? Will the DBInsert object now be tied to the session scope of the backing bean (i.e., when backing bean is deleted, the DbInsert object will be deleted from session scope as well.)
Ideally I would like the data access object to be available as a shared object throughout the life of the application. When I was programming using a servlet approach, I would have created a servlet to load on startup. Now that I'm using java server faces, I'm confused about the scope / how to efficiently set up a data access object that I want to be available to all backing beans in the application.
tnanks for any help understanding this.
Tom

I was thinking about setting the data access object as application scope so that it can be used by an backing bean to execute sql statements.
If I do set it as application scope, however, if I do this, do I still need to declare a new instance of the object from within each bean that uses the object?
For example do I need to declare a new instance of the data access object from within the bean? or, should I assume that there is always an instance of the bean available in the application scope, and if so, how do I reference it from within the bean?
Bean Code:
public class EnrollIspBean {
// DbInsert is data access object
private DbInsert dbinsert = new DbInsert();
Finally, I understand performance may be an issue if I have one instance of the data access object available in the application scope - is there a way to make multiple instances available in the application scope?
thanks

HDMI and PC inputs do not work on my 37AV502R LCD TV

HDMI inputs and PC inputs do not work consistently
my Apple TV (HDMI) and computers 2 on HDMI, 1 on PC, display just fine n the TV but after a while the TV goes blank,
the time is not consistent sometime a few minutes, sometimes a few hours,
but every time, after the TV goes blank there is nothing I can do, the TV just stays blank, if I unplug and turn back on the TV displays the image for a split second and goes bank again,
I thought it might be an overheating thing, however sometimes the PC input will stop working but the HDMI input (either one) will work fine,
has anyone else had this issue?
Thanks
A.

I'm having the same issue. As soon as I connect it to VGA or HDMI, it goes into a cycle of flashing on-and-off. A guy on youtube had the same problem (posted a video identical to my problem) and reportedly fixed it with a firmware update.
The problem: the US website doesn't have a firmware download. The canadian website does, but the update is from 4/2009, and the manufactured date on the back of my TV is 5/2009. (I also tried the update, but it didn't fix the problem).
When I call Toshiba to ask about the firmware update, after they confirm I am out of warranty, their automated system keeps hanging up on me. So frustrating.

Getting parameters from text and file input tag. . canyou help me ?

Hello!
Is there anyway of getting parameters from an
text field input in a form like :
<form name="signinForm" method="post" action="uploadFile.jsp" enctype="multipart/form-data" >Actually I would like to insert the parameters and make the upload of an file
on the same form. It is something likethis :
Form.jsp
<form name="signinForm" method="post" action="uploadFile.jsp" enctype="multipart/form-data" >
<input type="text" id="name" name="signinName" />
<input name="signinFile" id="fileUp" type="file" />
<input type="submit" id="submit_btn" name="signinSubmit"/>uploadingFile.jsp
<%@ page import="java.io.*,javax.servlet.http.HttpServletRequest,javax.servlet.ServletInputStream" %>
<%@ page import="java.io.FileWriter,java.io.IOException" %>
<%
.//upload the file
String email = request.getParameter("signinName").trim(); //this line is bringing me an NullPointerException
%>Thanks in advance for any suggestion!!
All the best!

You cannot use the HttpServletRequest object to retrieve parameters from a multipart form. You'll have to use a package that can parse such a form. I suggest Apache commons FileUpload.
http://jakarta.apache.org/commons/fileupload/
Using this package you can get both the file upload and any other parameters.

Simultaneous analog output 1k sine wave and data acquisition

Although many topics of simultaneous analog output and input can be found in NI Developer Zone, I have not found a case similar to my project. I'm trying to generate a 1kHz sine wave by using the analog output of NI DAQPad-6070E, and acquire one channel input signal simultaneously. I found most of the examples can not work properly above 100Hz. Any suggestions are welcome. Thank you.
Jian

I have sucessfully solve the problem when I observed the increase of
scan backlog number. Simply increase the buffer size of AI/AO and you
can make the 1kHz sine wave output and data acquired properly.

Report doesn't recognize the member ID and data not displayed

Hi Experts,
we have a problem with EvDRE Input schedule or report is related to insert member function .
When the regional config is set to comma for decimal symbol and point for thousands symbol.
If the user inserts a member which includes numbers and a point.
The BPC report inserts a new line with the ID replacing the point for a comma.
1. Logon BPC Excel -and open Input Schedule . Enter Decimal Figure
     Ex : 2007.TOTAL   2222,2222
2. Send data to server and press refresh worksheet. Its aggregation in "2007.TOTAL"
3.Then I have refreshed, I enter data in in another cell and send data,all r fine now again.
4.Wait 2 to 3 minutes nothig happend in the system (BPC Exl).Then press REFRESH button.Exept TOTAL have chnaged its value after decimal place-round proces happend.
5.Press Expand All. Result looks like : Some figures from Total level disappeared,values after decimal point still rounded.
6. Send decimal figure to the server and after sending process completes. I refresh ,figure in this cell becomes rounded
7.Then I Logoff from the BPC Excel and logon back.Open the same input schedule .Values are correct again.
8. Send data --Refresh ..its working fine.
The decimal process is rounded and disappearsometimes.Please suggest.Thankyou.

Problem with context mapping and data flow in a FPM application

Hi All,
I am trying to develop an ESS application using FPM. For the same, the requirement is to see the history of an employee in the second view.
The first view has got just the overview information and the second one has got the detail. So, the records or the fields are the same on both the views.
As per the FPM guidelines, the Model is residing in the Fc component and the respective Vc components are using the model data accordingly.
I am executing the model in the Fc component calling the executable method in the interfaceController of the first view and then trying to display the output data of the BAPI in the first view which provides the overview information.This is working fine.
But when i am trying to map the same output node to the Table UI for the second view, the record size is coming zero and thus no information is available.
For the above issue, I am again executing the RFC in the InterfaceController of the second view to populate the records, which is incorrect as it is already executed and the data is available for the first view.
I request you to let me know the correct approach to Context mapping and data flow when using FPM-roadmap. Is their any standard method or approach available to deal with such requirements? Please let me know.
Thanks in advance.
Regards
DK

Hi Idhaya,
I model node is available in Fc and the Fc interface controller is being used in the first Vc and the second Vc.
So the idea is, as the executable method is generated in the Fc, so i have created a custom method to call the executable method in Fc, where the input parameter is getting passed and this custom method is finally getting called is the first Vc.
So , now my first Vc is ready to call the custom method in Fc and execute the RFC. Once the RFC is executed, the nodes in the Fc should get populated which is the ideal case.
And as the Fc is used as a component in the second Vc, the same node is available to the UI elements.
But, when I check the record size for the output node, it is always zero, for the second Vc.
Regards
DK

What's the difference between "PreparedStatement" and "Statement"?

What's the difference between "PreparedStatement" and "Statement"?
Which is better??????

Read the docs for the two classes. The differences are apparent there.
Which one is better depends on your needs. I think that constructing and executing a PreparedStatement can be a bit less performant than just a Statement, if you're only executing the query one time. But I don't think that difference will normally be noticable in the context of a given application.
Additionally, if you have to pass any dates or strings to the query, you'll want PreparedStatement's parameters, rather than trying to format and escape things in the query string.

Tree-control for data input?

Hi,
I need to program an input screen for values that have hierarchical dependencies (e.g. sums). I feel, the most adequate user-interface would be a tree control, because of the data dependencies and also because the users asked for a possibility to collapse/expand parts of the data during input.
I had a look at CL_GUI_COLUMN_TREE, but I'm not sure, if it can be used for data input. Has anyone done something like this before or can anybody direct me to some additional sample coding? (the sample coding in the reuse library didn't do it...)
Thanks for your help, greetings, Kathrin!

Hello Kathrin,
Since you say that the user's input is hierarchical in nature, it is nice to have a tree-control for input. But, the choice of using a custom-control-version of the tree is a cause for some concern. I cannot recollect any of the SAP screens where the input can be given through such a tree framework (please do let me know if you have come across one). The problem with such a tree would be in the areas of even-handling. Filling the tree with appropriate data at the right times would be another challenge.
However, there's one alternative that I would like to direct your attention to. You must have observed another kind of tree, when you select an application component from the APPLICATION HIERARCHY, which is just like a list. Also, the <i>Transport Organizer (SE09)</i>, <i>Menu Painter (SE41)</i> etc., have this kind of a tree. You can use this if you (or rather your users) are very particular on having a tree display. For more information, you can see the Function Group <b>SEUT</b>, which has the required function modules to accomplish the same. The Function Group is well documented, and you might have to work a little on the function modules themselves.
Please do let me know if this is a suitable option to meet your requirement. All the best,
Regards,
Anand Mandalika.

[Solved] CUPS: Unable to write print data: Input/output error

I'm filling this for the benefit of those poor googlers that can reach here.
Symptoms: After trying to print a "complex" image the printer made too much breaks, and failed.
The problem is, it then didn't came up. I mean, I restarted the printer, cupsd, the whole system, and nothing.
I was unable to print again, it showed "Unable to write print data: Input/output error" and refused to print anything.
I then saw that in /etc/cups I had printers.conf and printers.conf.O files, which differed (other than in StateTime), that printers.conf.O had
State Idle
but printers.conf had:
State Stopped
StateMessage Unable to write print data: Input/output error
Reason paused
Probably due to the ErrorPolicy being stop-printer.
So seeing I followed the following steps:
Stop cups
Replace printers.conf with printers.conf.O (I could also had manually edited it)
Start cups
It then went working flawlessly.
There was probably an option in the web interface combobox for doing that. The problem is that I didn't realise it was stopped, so didn't know how to make it work. Moreover, some posts in the web recommended reinstalling the printer (which would skip the problem by creating a new printer).

I think that I had this same problem, and fixed it by reinstalling the printer. Thank you for your post.
