Sample Servlet code that connects to Microsoft SQL 2008

Does anybody have sample Servlet code that connects to a Microsoft SQL 2008 Resource Pool?
Thank you.

JDBC is used to talk to databases. Not database utilities. As an example SSIS is not a database.
So the question would be is the 2008 "Resource Governor" (of which "Resource Pools" are part) a utility or a database entity?
[http://technet.microsoft.com/en-us/library/bb933866.aspx]
I would guess that it isn't a database entity.
Thus the only way to access it is if a database entity allows you do access it. And for that you would need to look for SQL Server system proc(s).

No parms passed to controlling servlet

I want a page with an inputfield, 2 selectboxes and 1 (or more) submit-buttons. User MUST select a button before 'controlling servlet' is executed. (I mean, no action when 'enter' is used).
These are the 2 scenarios I tried:
Scenario (A)
When i put the <Form ...> tag at the top of my jsp and include inputfields and buttons, I get a 500_error when the cursor is in an inputfield and users presses 'enter'.
It seems that the parameters are not correctly passed to the 'controlling servlet'
However, when I
1) 'click' the Submit-button
or
2) 'click' outside this inputfield and then 'enter' or 'click' the Submit-button
the parms are correctly passed and 'controlling servlet' is correctly executed.
==>
<FORM action="/servlet/com.clipper.servlets.FQController" method=POST>
<td width="150" height="25" colspan="3" bgcolor="#FFFFFF">
     <INPUT size="15" type="text" maxlength="15" tabindex="1" name="agency" value="<%= ((String) session.getValue("sessionid.useragencycode")).trim() %>"></td>
<td width="600" height="25" bgcolor="#99CCFF" colspan="12">
<p align="left"><INPUT type=submit tabindex="5" name="action" value=" List "></p></td>
</FORM>
Scenario (B)
I changed code and do not have the 500_error when in inputfield but no parms are passed anymore.
This is the code
==>
<td width="150" height="25" colspan="3" bgcolor="#FFFFFF">
     <INPUT size="15" type="text" maxlength="15" tabindex="1" name="agency" value="<%= ((String) session.getValue("sessionid.useragencycode")).trim() %>"></td>
<FORM action="/servlet/com.clipper.servlets.FQController" method=POST>
<td width="600" height="25" bgcolor="#99CCFF" colspan="12">
<p align="left"><INPUT type=submit tabindex="5" name="action" value=" List "></p></td></FORM>
What is the correct implementation of this ?

1. your text field or any other form fields have to place between the <form> and </form> tag..
2. I don't know why you didn't get any paramter values, but you can write a function to list all the parameters that were in the request, call the function in the beginning of your control servlet.... Below is a sample...
     public static void listParameterValues(HttpServletRequest request) {
        Enumeration names = request.getParameterNames();
        if(names != null) {
          String name="";
          while(names.hasMoreElements()) {
            name = (String)names.nextElement();
            String[] values = request.getParameterValues(name);
            if(values != null) {
              for(int i=0; i<values.length; i++) {
                System.out.println("listParameterValues(), " + name + "[" + i + "] = " + values);

Teststand Manager Controls in Code Modules

I am trying to understand how UI controls work in code modules called by TestStand steps. I can pass a reference to an Application Manager (perhaps the application manager?) to my code module using RunState.engine.GetInternalOption(InternalOption_ApplicationManager). Does the sequence editor have an application manager? Or the engine? Is this the same as the Application Manager control I put on the front panel of the code module? What about SequenceViewManagers and ExecutionViewManagers? Can I create those in my code modules to display sequences or executions? Or can I somehow get those from the sequence editor/engine, or from the Application Manager?
I know that I just asked a lot of questions, but I guess what I am looking for is some general guidelines for using the manager controls in code modules. This all came about by an attempt to display an Execution View Manager control in my code module. Feel free to ignore the following description of my various attempts to get this to work. This exercise helped me understand the managers a little bit more, but I'm still a little confused.
Suppose I want to create a custom step type for debugging to display the variables for the current sequence context on the front panel of a code module VI. (LabVIEW 8.6, TestStand 4.1.) In my code module, I call ExecutionViewMgr.ConnectVariables to connect to a VariableView control. Where do I get my ExecutionView Mangager from? I tried two methods:
1) create an ExecutionViewManager control; set the manager's current execution using ExecutionViewMgr.Execution (pass RunState.Execution from TestStand to the code module).
It seems like this should work, but when I run my sequence from the sequence editor, the ExecutionViewMgr.Execution property node returns error -17500.
When I run from a LabVIEW Operator Interface (using the LabVIEW environment, not the exe), I don't get an error. But I must connect a list control using ExecutionViewMgr.ConnectExecutionList, and select the execution from the list when the code module is running. Then I can see the variables when I select the execution in the list. However, the execution display on the OI goes blank. I can see either the variables on my code module or the execution on my OI, but not both simultaneously. It appears that an execution cannot be attached to more than one manager at once (I guess that's reasonable).
2) pass the result of RunState.engine.GetInternalOption(InternalOption_ApplicationManager) to the code module; set the manager's current execution using ApplicationMgr.GetExecutionViewMgr() (pass RunState.Execution from TestStand to the code module, then as a parameter to GetExecutionViewMgr() ).
In this case, I would expect that there is no ExecutionView Manager associated with the execution when running from the sequence editor. But the ApplicationMgr.GetExecutionViewMgr() function returns a non-Null reference. ExecutionViewMgr.ConnectVariables() causes an error dialog to be displayed (from the function itself, not from TestStand), although it doesn't actually output an error (and the VariableView control remains blank). The error is "Unable to connect Variables View control." (See attachment.)
When I run from my LabVIEW OI, it works perfectly--I see the variables on my code module's UI, and the execution appears on the OI simultaneously. I guess this makes sense since the TestStand engine is returning the Execution manager that was already created by the OI.

TestStand only allows a single ApplicationMgr per process, creating a second one will error. So the engine will always return the one in either the UI or the Sequence Editor. Events should be seen by both handlers. You have to be careful to ensure that your extra handler does not mess up the UI's handler if yours is called first, like preacknowledging a message. As far as setting up a handler in a code module, you should be able to. However, we have not fully tested this capability, so we cannot say that we fully support this because you might run into issues. In addition, using LabVIEW might present additional issues that might not be seen in other development environments like CVI and Visual Studio. Performing some functionality that can process messages in a COM callback can cause potential hang conditions, to the less you do in a callback the better when using LabVIEW. Keep in mind that you have to ensure that you unregister your handler if the code module returns to the calling execution and you no longer want the handler to be called.
Attempting to use a new TestStand UI control in a different thread than the UI thread is not recommended because we have done almost no testing on this use case because it is not done in typical UIs.
Now, for customers that want to create a nice GUI that includes serial number prompting, but still want to be able to work with the Sequence Editor, I suggest that you implement a behavior that works with a supporting GUI, but support an alternative when a non-supporing GUI is present.
For example, you could do the following:
1. The process model can send a custom UI message synchronously to the GUI to ask for a serial number. The custom message would contain a reference to a property that contains (a) a boolean to indicate that the UI will "respond" to the message, (b) a string for specifying the serial number, and (c) a notification object from the TestStand Synchronization Server.
2. When receiving the UI message, a supporting UI will set the boolean to True, duplicate the reference passed locally, and acknowledge the UI message.
3. When the UI message returns, the exectution will determine if the UI supports the message. If yes, the exectution will (a) wait on the notifcation (b) When the user enters a serial number, the GUI will set the string property and then pulse the notification, and release the reference to the properties passed via the UI message. (c) The execution will return from the notification wait, read the serial number, and continue execution.
If no, the execution will need to use the default process model prompting or custom prompting that you devise when using the Sequence Editor.
The process model could use a UI message to determine if the GUI is supportive of this mechanism once instead of with each serial number prompt, but you get the idea.

How to disable client cookie using Servlet code

Hi All,
          I want to disable the client cookie using JSP or servlet code.Is it possible how I can do it.
          Thanks in Advance .

Hi,
          first of all, the URL rewriting option (URLRewritingEnabled) in the weblogic.xml must be set to true.
          Now, for all first-timer web requests the BEA WLS always uses URL rewriting in addition to cookies to see wether the browser accepts cookies or not.
          I would try to rip of all of the cookies in the header, then flush the response to force the http header to be written.
          I have never tried it and has no idea if it will work, however the teory behind supports the idea.
          This will not work for toggling session tracking mechanism from a session already established with cookies, the session will be lost if attempted to do this without the URL-rewriting enabled on the page.

How to find a control with code

I could find the control with the Test Builder, but now, what I want is achieve that by code. How could I define what the property
to search? Any help would be appreciated.

Hi mokpoju,
Generally, I know that if we want to find a control by code, we will need to add the searchproperties or filterproperties to find this control in the UIMap.Designer.cs file.
For example, you could use this searchproperties or filterproperties to find the control's ID, Name properties etc.
For more information, please refer this following blog to check your issue.

Nedd to find basic servlet code

Java novice
I need basic servlet code that will capture the input of one form field and write it to a flat file on the server. Servlet will be called in html form action. Any good sources to start with? It appears that this is so basic that I've had trouble finding anything out there.
Thanks

If what you want is to learn the basic stuff invloved in doing what you want to do.
Just follow the java servlet tutorial and io tutorial (You can use google to reach those)

How to I get rid of pop up user account control "do you want to allow the following program to make changes to your computer" I have windows 7 professional.

I keep getting an annoying pop up the says "User Account Control" "Do you want to allow the following program to make changes to your computer"
== This happened ==
Every time Firefox opened
== Two days after I downloaded Firefox and set as my default browser.

Check that you do not run Firefox as Administrator.
Right-click the Firefox desktop shortcut and choose "Properties".
In the Compatibility tab, make sure that Privilege Level: "Run this program as Administrator" is not selected.
You also need to check the Properties of the firefox.exe program in the Firefox program directory.
If you can't make the changes then you need to start Windows Explorer as Administrator.

Flush parameter of jsp:include has no effect on servlet code

I am running 9.0.3 and my jsp code looks like:
<jsp:include page =".." flush="false"/>
but the resulting servlet code is:
pageContext.include( __url);
Which defaults to flushing the buffer!
Does anyone know a work around or if Oracle is going to fix this?
Thanks,

Try:

       if (hintsMap == null) {
            hintsMap = (Map)(Toolkit.getDefaultToolkit().getDesktopProperty("awt.font.desktophints")); //NOI18N
             if (hintsMap == null) {
                hintsMap = new HashMap();
                 if (antialias) {
                      hintsMap.put(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
       return hintsMap;
... later in class ...
    @Override
    protected void paintComponent(Graphics g) {
        Graphics2D g2d = (Graphics2D) g;
        g2d.addRenderingHints(getHints());
        super.paintComponent(g);
        ...needed this so custom paint would use AA. In my app I wrote text in my component and it was not AA, this turned it on.
I don't think I had the same problem you, as my jlabels were always aa.

In Windows 7, Microsoft updated UAC in several ways. By default, UAC does not prompt when certain programs included with Windows make changes requiring elevated permissions. Other programs still trigger a UAC prompt. The strictness of UAC can be changed to either always prompt, or to never do so.

In OS 10.5.8 where are the controls or code for selecting dragging/moving files and folders copying and pasting kept?
Is it part of one of the system apps?
Mine do not work any fixing tips?

Good call on on throwing away finder plist It worked on my desktop/screen saver problem...But, it didn't fix the dragging and moving items/folders and paste.
My network is still confused too.
I threw out the desktop plist as well still nothing...
I did run the anti-virus Macscan to check just for peace of mind it did find a spyware from CNN...
Thanks for your help at least one thing worked so far.
Any other suggestions, besides reloading OS...?

How to retrieve "env-entry" in servlet code

i have a pretty straight-forward web app, which contains a servlet, among other things. the web app is packaged in .war, and it in turn is part of a .ear file. i am using WAS 640 sneak preview on windows xp.
in the web.xml file, i added the following lines:
<env-entry>
<description>some texts</description>
<env-entry-name>myapp.home</env-entry-name>
<env-entry-type>java.lang.String</env-entry-type>
<env-entry-value>c:/myapp</env-entry-value>
</env-entry>
in my servlet code, i try to retrieve the value for "myapp.home" like this:
try
Context ctx = new InitialContext();
home = (String) ctx.lookup("java:comp/env/myapp.home");
} catch (Exception ex) {
ex.printStackTrace();
after .ear is deployed, i can see in the JDNI Registry (using Visual Admin Tool), myapp.home is added to the tree:
webContainer
-applications
--myCompany.com
---myEarFileName
myWebAppRoot
java:comp
env
myapp.home
the entry has the correct class name and object value.
when the servlet code that performs the jndi lookup is called, i get an exception:
com.sap.engine.services.jndi.persistent.exceptions.NameNotFoundException: Path to object does not exist at : java:comp
??? QUESTIONS:
#1 what am i doing wrong?
#2 if the lookup name must contain the entire jndi tree as listed above, then how can this code be portable to other app servers?
thoughts are greatly appreciated.

thanks for the hints, but unfortunately they didn't work.
1. after switching the order of value and type in env-entry, rebuild/redeplpoy, same exception. the ordering probably didn't matter since even with the reversed order, the name and value showed up correctly under the jndi tree.
2. well, i tried giving it the full path, starting with 'webContainer', then 'applications' etc, separated by forward slash. now the exception says path to webContainer is not found.
so what gives? are there no standards?

How to translate this statement to java servlet code

INSERT INTO table_name (column1, column2,...)
VALUES (value1, value2,....)

You wouldn't translate that statement to servlet code. The idea doesn't make any sense. However you might include it in a servlet; read the tutorial that zadok linked to.

Compiling servlet code

I m new to servlets.
I just copied a servlet code from servlet Help.Then tried to compile with it JDK1.3.But it showing error.It is not compiling package Javax .What may be the possible error.

Right, the javax.servlet packages are not part of J2SE.
You'll need a servlet engine to run your servlets/JSPs. It'll have the servlet.jar containing the javax.servlet packages. You'll have to add that to your CLASSPATH when you compile.
I'd recommend Tomcat as your servlet engine. It's capable and free:
