• How to insert a value obtained from pageContext.

  Dear friends,
  
  I value from URL, and I get by using pageContext.getparamter (), now, I want this value
  to insert in a table attached to the same page.
  
  How can this be achieved? Please share your ideas.
  
  NOTE: I use insert EO.
  
  Thanks in advance,
  Had

  Capture the data and the attribute VO in which you want to save, and set its value. Here's the dummy code, you can refer:

  String v_projNumber = pageContext.getparamter ();

  OAViewObject vo = (OAViewObject) am.findViewObject ("XXViewObject");
  If (vo! = null)
  {
  vo.getCurrentRow () .setAttribute ("projectNumber", v_projNumber);
  }

  A question, if you want to save this value in a Table view attribute, then will fill the same value for all the lines in this region of the table.

  The code above is not for the region of the table. For the table, you will need to loop through the line of VO and having to return to the selected line and setAttribute it.

  Thank you

• Data from Web service to a Web service that keeps the Session control

  Following the example set by Rama cricket in [maintaining Session with JAX - WS | http://weblogs.java.net/blog/ramapulavarthi/archive/2006/06/maintaining_ses.html]; I could create a WebService that keeps the sessions using JAX - WS.
  
  Now, I want to use this WebService, from control data in an ADF application, but unfortunately, I do not know how to tell from this data control that I want to maintain the session.
  
  I don't know if I should extend and overwrite the FactoryClass (oracle.adf.model.adapter.DataControlFactoryImpl) or if I have to do with the application definition (oracle.adfinternal.model.adapter.webservice.WSDefinition)
  
  I'm new to ADF and I understand that it can be simple, I just need an example or documentation to read.
  
  Thank you

  For the service, you can create a proxy of jax - ws and as mentioned in the document that you cited, activate the session on the client.
  This client class, you can then create a data bean control and use it in your ADF application.

• Manage the Session Timeout

  I use JDeveloper 11.1.1.6.
  
  I'm trying to properly handle session timeouts in the ADF. My request was the popup of session ADF 'canned' timeout when I am connected to my request and the session has expired. This same popup is rendered even if I'm sitting at my login page, but are not registered.
  
  I followed the advice of Frank Nimphius as explained in the next forum so that my request of re - direct to the login page after session timeout. That works very well with his detailed document.

  The concern I have now is if I'm sitting at my login page and my session expires, demand remains at the login page. I now have my credentials of type, and click Connect. Because the application think that my session has expired, I picked at the login page. Ideally I think not that the login page would hold a session. You have any indication on how I can get around this.

• Ajax call resets the session?

  All,
  
  I got a general question about AJAX calls. During an Ajax call, which resets the session? I mean, if I put the session expires after 30 minutes and does it not everything hits server other than Ajax calls for 30 minutes, the session expires?
  
  Thanks in advance.

  Session is kept alive due to the client HTTP calls. AJAX calls are HTTP requests. So no, the session has not expired.

• OpenScript / database: String obtained from the data bank cannot be used for parameters

  Hello
  
  I add a jar to java code OpenScript file. Since the need to enter the settings of the front console run the jar file, I think that it can read the settings from the database and then run it as "java-jar filename.jar para1, para2 para3", 2 3 para1 is synonymous with three parameters obtained from the database "
  
  I get the value of the database as follows:
  String para1 = "{{db.caseName.para1}}";
  String para2 = "{{db.caseName.para2}}";
  String para3 = "{{db.caseName.para3}}";
  
  However, it does not work and it looks that this string has the database cannot used as settings in 'java-jar filename.jar para1, para2 para3.
  I'm trying to assign the value directly as: String para1 = 'PARA1 '; String para2 = "PARA2; String = 'PARA3; then can run 'java-jar filename.jar para1, para2 para3' and this can work.
  
  So, how can I use parameters got in 'java-jar filename.jar para1, para2 para3' database successfully?
  Thank you very much ^ _ ^!
  
  Kind regards

  Hello

  You can use eval() for this. That is to say. Use the following method

  String para1 = eval ("{{db.caseName.para1}}");
  String para2 = eval ("{{db.caseName.para2}}");
  String para3 = eval ("{{db.caseName.para3}}");

  then run "java-jar filename.jar para1, para2 para3.

• Draw a XY spectrum obtained from a spectrometer in LabVIEW using the XY Chart

  I need to draw a spectrum obtained from a spectrometer in LabVIEW using an XY Chart. The data is stored in 2 columns in a spreadsheet form (counts against the wavelength) & using "excel.vi reading" ideally I should be able to trace this spectrum. The spectrum has averaged 1 data points k.

  However, I am not able to get the chart by using this method, please suggest a change or provide me with a sample .vi as an example to understand.

  Thanks in advance...!

  Excel is a format binary owner and you need special tools to read directly. (There are plenty of ways to read, here is an example, here is another one, but I tend to avoid these formats)

  You could use excel to export the data as a text file (separator: tab), and then read using "" read the worksheet file". Once you have the data in a table 2D, just the graphic columns both. (See attached example)

  Assuming that you have read the file in the form of a 2D array, here's how you would it chart. (For simplicity, I copied the data from excel to a constant string diagram).

• How to make a graphic inside a while loop to maintain the previous values

  At first I tried to use a the VI Express XY graphics to create a track of points.  However, the chart is a trace linear between the first point in the new line and the last point of the previous line.  It then creates the new line as you wish.

  I tried to use a loop with group a cluster for the chart, but the chart resets the plot at each iteration (as expected) and I can't find a way to maintain the previous data.  I tried using shift registers, but was unable to find a way to do it, and I tried also the cluster of a painting company, but can not find a way to make the cluster to a 1 d of a cluster of 2 elements array.

  One option is to have is to find a way to maintain the previous data, but the preferred option is to create a new path to each iteration to see the color change for each new parcel.

  I take stabbed it because I don't know exactly what you want. But I think that's what I've shown here. You must use a shift on your outside register while loop, as I showed. Your image where you tried to use a shift register shows a misunderstanding of the shift registers and how well they work, then I'd take a peek at these tutorials.

• Can move us the session values to with ExecuteParms

  Hi experts jdev,.
  
  With the help of 11.1.1.5.0 - adfbc jdev
  

  normally what we do in execute with params. manullay write query something
   like ah:
  select * from employees where empolyeeid= :eid 
  
  here 
  eid is bindvariable.
  
  drag and drop in the type of  execute with params into jspx page it will works fine.

  but my only requirement same thing is added.
  

  i will explain in details from start to end.
  i had employee login page.
  
  Username:100       // this username holds in session
  password:100
  
   login button
  
  enters into index page welcome "100" 
  
  when hits search page search page opens
  
  search page means i write vo as :
  
  empsearchvo
  
  select * from employees where empolyeeid= :eid and salary = :sid
  
  bindvariable

  af:table details
  employeeid  | salry | address  | and so on details.

  is it possible. ?
  
  Why am posting the thread means session value is ui not come. so I can't get my result in af:table.
  
  can someone help me? outside.

  You must assign the session for the parameter variable to the link of your page layer.
  Select the link of your JSF page, look for the execute with params - look for setting set the NDValue to point to the value of your session.

• How to maintain the synchronization of the hierarchy of the table with customer-specific data

  Series of paintings in our system, we have:
  
  Promotions (id, descr, datefrom, dateto,...)
  PromotionClients (promotionId, clientId) = list of clients whose promotion is valid
  PromotionProducts (promotionId, itemId) = list of products on sale
  
  The synchronization logic is simply that all promotion tables must be synchronized just to the customers present in the PromotionClients table. So each select element for these tables of publication contains something like "... and there are (select 1 from c PromotionClients where c.clientId =: CLIENTID). It works fine until there are some changes in the PromotionClients table. After the change of PromotionClients table starts to sync, but other tables do not - there is in fact no updates on their respective folders.
  
  Is there a solution to this problem other than to manually create the triggers for the PromotionClients table that would execute model-update on each related table? I mean - is there an existing function in OracleLite that woud let set a few references - to load to a point of publication/table?
  
  And in the face of similar problem - there is also Promotions.datefrom/dateto limitation. Promotion tables must be synchronized at the time where actual date is between Promotions.datefrom and dateto. When someone modifies some of these values and so the promotion valid for the time related tables does not automatically update and so they do not start to synchronize. Just the Promotions table begins to synchronize. So we might need to implement another trigger to perform updates dummy on the tables of PromotionClients + products, Promotions.datefrom/dateto update.
  
  I do not like the personalized relaxation approach - it just duplicates the synchronization logic and it is inconvenient to maintain the synchronization logic in two places (pubitem selects + custom triggers). I would like to find a solution of OL-native - as referring to load tables for each publication element that would cause triggers to OL to also catch the person in charge of the lines of tables (which were not actually modified) to be marked as dirty and synchronized to the client. Is there a solution like this? Or is there an alternative better than custom triggers?

  When you trigger an event in a related table, it gets registered for PGM compose the data in this table. If there is a suspicion, MGP will compose the data in these tables as well.

  So if you have something like a REGION_MAPPING table that maps the users in various locations and if you change the table data and want other tables that are joined with him to compose the data, and then add a hint of dependency to the tables mapping them to REGION_MAPPING. If these tables is regularly updated and data are being composed for the child tables, then you don't need the trick, just good practice to add it.

• I want to maintain the "frequency of sampling to report signal frequency" a constant.

  I want to generate sine waves of varying frequencies, say, from 1 Hz to 1 kHz. Sometimes, a swept frequency sine wave. The problem is that I want to maintain the "frequency of sampling to report signal frequency" a constant. That means, the sampling frequency must be 20 or 30 times the frequency of the signal. This should be done automatically. For example, a sweep of 1-10 Hz, if the sampling frequency is 30 Hz at the beginning, it should be automatically updated at 300 Hz as the frequency of the signal reaches 100 Hz. Someone you will suggest a possible solution?

  The basic generating function function has an entry titled "sampling info". It is a cluster and one of the elements is the number of samples. You just need to set this based on your frequency.

  

  I suggest strongly that follow you the course 101 of LabVIEW.

• How to maintain the life of your printer

  It seems more common that everyone feared how to maintain the service life of the cartridges from the printer itself.  As many variations of parameters and environment may play a role in how long your ink will actually last. A more official document can be found here about the science behind the ink, how to use it and how to make it last longer.  I will get into issues that affect the overall performance and life cycle of the printer.  I recommend to use the Startup ink supplied with the printer until he is gone because it contains chemicals of this condition and prolong the life of the print head for future use.

  I urge users to keep the printer connected directly to a wall outlet (namely for troubleshooting purposes). As with all electronics that are showing signs of failure, you can start with the power source if one really wants to follow the flow of a schema logic.  By eliminating the devices that can not to themselves, you removed a piece more equipment from the equation.  A more specific reason would be due to electromagnetic interference.  Wireless devices are vulnerable to interference with symptoms like error messages of false, lines in digital images, strange noises and frequent jams.

  Surge protectors must regulate the power distributed to each connected device.  It is possible that the printer is not the right amount of power and may fail as the printer power problems in hibernation mode with more features like duplex printing, it is impossible to recover , cable USB not detected and the light on the module displaying a yellow instead of green.  If the module and the surge protector are fighting for the control, it can cause a variety of problems that could easily be repaired by plugging the printer directly into a wall outlet.

  The next major issue many users face is the print head.  It is as well as the maintenance of ink as well.  It is important to clean the print head and the best way to do that is to use it and keep the good ink in the printer.  Over time, the chemicals can not even begin to change or develop air bubbles in the cartridge.  Not to mention, ink (well pigmented) still contains fluids that can evaporate if the printer is not rooted and off properly when not in service.  Of course, some of the processes of preparation printer used when the power of the printer can use very valuable ink, but, on the other hand, it's good for the life of the printhead to leave these processes to perform according to its specifications.

  The print head is composed of tiny nozzles and parts fragile this is why it is also one of the most expensive areas of the printer.  Most printers contain many self-cleaning utilities which is recommended to regularly (I suggest at least once a month) to help keep the printhead clogging and causing stains on the sheet itself. There are a number of unconventional methods to try once the printhead has dried up in fact, but when you try these steps you may totally break the part.

  Dust and smoke particles can also cause problems with the print head, but the printer entirely.  It is often the main killer of electronics as well as hairs and animal dander, dirt from moisture and humidity, paper for printer cheap and sand.  The air is full of impurities and really can not be prevented.  Preventive measures can be taken with dehumidifiers and a uniform cleaning, but over time, there is no real way to prevent it from happening.  Dust and air blowers have been known to cause not only solders to separate but may deposit particles of dust in places that could actually damage the printer entirely.  Instead, a favorite device is known as an empty computer.  It helps to remove the fine dust in the sense just that pushing forward into the printer.

  Paper jams also cause many more problems if is not removed correctly. HP recommends pulling the paper in the direction of the gears.  When removing a paper jam, you won't hear a grinding because it leads finally to the teeth are stripped like a screw, but simply once fully detach one of these devices. It is virtually impossible to fix a paper roll or similar because all parts are connected to each other and not sold in parts stores.

  At the back of most HP printers, you can remove the rear access door or duplexer (double-sided printing device) and easily join the paper in this way.  If you see the paper jam is located next to the Board, and then remove the piece from the back and take the paper with both hands to apply a gentle tug of same, and you should have no problem in removing the paper in this way.

  Paper quality can play a large role in the life of your printer.  Cheap paper can free of paper dust up into the gears and small machinery within the printer and are very difficult to clean.  Print incorrect parameters and issues related to food can cause the paper to stay in places that are not as easy to do.  In this case, remove the paper as long as slowly and patiently as possible to avoid them ripping out pages in places like between the wheels under the printhead and also causing error messages that will not disappear.  When troubleshooting printers, patience and troubleshooting documents will also help you keep your printer running longer.

  The printer doesn't like to not be put off by anything other than the power button.  I have always recommended the printer off when not in use (at least for long periods of time) to help keep the ink dry and high printing quality.  The reason why it is not recommended is because people will be unplugging the printer, while he is doing something and the negative effects that this might have some alignment problems serious, burn the computer chips and components similar to that in computers, fake error messages and possibly bricking of the printer if done at the wrong time.  Resets hard are great troubleshooting steps, but the abuse of this feature can result in irreparable damage.

  Fanning the paper before put you in the status bar is a good practice. About 25 sheets are perfect, because an overload of the status bar may also cause paper jams.  The paper guides of setting and selecting the appropriate paper type will put the science behind these settings wisely. Don't put paper in the tray while the printer is printing, crumpled, dirty, or coexist paper types and paper clips are all things to avoid.

  Software and communication issues deserve a section all to themselves.  The measures to prevent problems of this kind could not covered in a post, let alone a chapter.  The best thing to do to increase the performance and connectivity is to set a static IP address in the URL embedded in the printer if the printer is set up on a network (steps to do this are different from the printer to the printer).  USB cables must not be more than 3 meters long and kept in good condition as well as the power supply cord.  Keep your valuables out of reach of children and buy an extended service plan for many reasons.  You can enjoy all the services offered with a service plan in the case of a defective printer or simple product questions.  Keep the firmware up-to-date and to read reviews before you buy any electronic device.

  After reading this, I'm sure you're aware, that's all common sense, but at the time where you do not consider one of these suggestions you think back and wonder "if I had taken 10 seconds longer to avoid that I wouldn't spend 2 hours more set.»  Mistakes are made when frustrations and lack of care.  These are not delicate machines that deserving the highest shelf in the bathroom, but an understanding must be met, that once it's broken this avoidable?

  Troubleshooting of many documents can be found at www.hp.com/support.  They must be followed in order to avoid the repetition of the steps, steps unnecessary and causing more frustration.
