  • Servlet request getparameter's performance

    - by Bob
    Hi, I noticed that my app is very slow sometimes, so I've done some tests. It's a very simple web app. One servlet gets some parameters than stores them. Everything's fine except one thing. It takes too long to get a parameter for the first time. It doesn't matter which parameter I try to get, but for the first time it is very slow. The strange thing is this doesn't happen always. Sometimes getting a parameter for the first time is not slow. My code looks like this request.getParameter("paramName"); request.getParameter("paramName2"); request.getParameter("paramName3"); Getting "paramName" is slow. Getting the others is very fast. By slow I mean : 200-800 millisec By very fast I mean: ~0 millisec (in the code snippet, I didn't write the performance test, but I'm using System.currentTimeMillis())

  • simplifying templates

    - by Lodle
    I have a bunch of templates that are used for rpc and was wondering if there is a way to simplify them down as it repeats it self allot. I know varags for templates is coming in the next standard but can you do default values for templates? Also is there a way to handle void functions as normal functions? Atm i have to separate them and treat them as two different things every where. template <typename R> R functionCall(IPC::IPCClass* c, const char* name) { IPC::IPCParameterI* r = c->callFunction( name, false ); return handleReturn<R>(r); } template <typename R, typename A> R functionCall(IPC::IPCClass* cl, const char* name, A a) { IPC::IPCParameterI* r = cl->callFunction( name, false, IPC::getParameter(a));

  • JSP getParameter problem

    - by user236501
    I have a form, if the timer reach the form will auto redirect to the Servlet to update database. My problem now is if javascript redirect the window to servlet my request.getParameter is null. function verify(f,whichCase){ if(whichCase == "Submit"){ msg = "Are you sure that you want to submit this test?"; var i = confirm(msg) if(i){ parent.window.location = "sindex.jsp" } return i; } } I doing this because i got a iframe in my jsp. Timer update problem have to use iframe. So, when time up or user click submit parent.window.location can let me refresh parent window <form method="POST" action="${pageContext.request.contextPath}/TestServlet" onSubmit="return verify(this,whichPressed)"> My form when user click submit button within the timing, it will trigger the verify function to let user confirm submit. So inside my TestServlet i got this, because using javascript redirect request.getParameter("answer") this keep return me null. protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { if (request.getParameter("Submit") != null) { String ans = request.getParameter("answer"); Answer a = new Answer(ans, no); aa.CreateAnswer(an,t.getTestCode(),username); RequestDispatcher rd = request.getRequestDispatcher("/sindex.jsp"); rd.forward(request, response); } } Below are my timer when time up redirect to TestServlet trigger the doGet method if((mins == 0) && (secs == 0)) { window.alert("Time is up. Press OK to submit the test."); // change timeout message as required var sUrl = "TestServlet"; parent.window.location = sUrl // redirects to specified page once timer ends and ok button is pressed } else { cd = setTimeout("redo()",1000); }

  • req.getParameter returns values wrong character encoding

    - by coder247
    I'm trying to get values from a JSP using getParameter which includes ü,é,à etc. But get wrong values in servlet. I've checked the content type with firebug and found that Content-Type text/html;charset=UTF-8 checked the POST section with firebug and found the correct value there, when I try to access it in servlet it is wrong. Gives ö instead of ö req.getCharacterEncoding(); returns null. Tried with setting req.setCharacterEncoding("UTF-8"); at the beginning of servlet but didn't help.

If I would need to register a new row in a table in the database, how should we pass the various value of column into the system? For example, the user might want to register a new event in his planner and the detail of the event involves the 'where', 'when', 'who', 'detail', etc. Should pass all this long value from the servlet's parameter, i.e: the http link? String accNo = request.getParameter("account_number"); String a = request.getParameter("..."); String b = request.getParameter("..."); String c = request.getParameter("..."); String d = request.getParameter("..."); To illustrate my view that it is really unprofessional to show all the parameter on the link: http://localhost:8080/domain1/servlet1?param1=55555555555555&param2=666666666666666666666666666666666666666666666666666666666666&param3='Some random detail written by user.........................' Is there other way to pass them?

  • Why Java servlet can't get Paypal IPN messages everytime ?

    - by Frank
    I have a Java servlet running on my notebook with Windows Vista, I set up a static IP, did port forwarding and registered for a free DDNS service, now my servlet is running, I gave the url to Paypal to send me IPN messages, I went on to it's sandbox site got to the test tools page, tried to send test messages by clicking the "Send IPN" button, most of the time it would fail, the error is : "IPN delivery failed. Unable to connect to the specified URL. Please verify the URL and try again." But maybe 1 in 10 times, it might be successful and my servlet would get the message, and I looked at the messages I got, they are in correct format. So I called Paypal asking why, he said I shouldn't run the servlet on my notebook, in stead I should run it on the web server, but I told him my ISP doesn't support Java on their server, and since I did all the above steps, shouldn't it be the same to run the servlet on my notebook ? He said his test showed he couldn't get to my servlet, but I asked why maybe 1 in 10 times it could get through ? If there is something wrong with running it on my notebook, then 100% times it should fail, am I correct on this point ? But anyway he said that's all he could do, and I should troubleshoot it myself. The servlet looks like this : import java.io.*; import java.net.*; import javax.servlet.*; import javax.servlet.http.*; import java.util.*; public class PayPal_Servlet extends HttpServlet { static boolean Debug=true; static String PayPal_Url="https://www.paypal.com/cgi-bin/webscr",Sandbox_Url="https://www.sandbox.paypal.com/cgi-bin/webscr", Dir_License_Messages="C:/Dir_License_Messages/"; static TransparencyExample Transparency_Example; static PayPal_Message_To_License_File_Worker PayPal_message_to_license_file_worker; // Initializes the servlet. public void init(ServletConfig config) throws ServletException { super.init(config); if (!new File(Dir_License_Messages).exists()) new File(Dir_License_Messages).mkdirs(); System.gc(); } /** Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods. * @param request servlet request * @param response servlet response */ protected void processRequest(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException { // Read post from PayPal system and add 'cmd' Enumeration en=request.getParameterNames(); String str="cmd=_notify-validate"; while (en.hasMoreElements()) { String paramName=(String)en.nextElement(); String paramValue=request.getParameter(paramName); str=str+"&"+paramName+"="+URLEncoder.encode(paramValue); } // Post back to PayPal system to validate // NOTE: change http: to https: in the following URL to verify using SSL (for increased security). // using HTTPS requires either Java 1.4 or greater, or Java Secure Socket Extension (JSSE) and configured for older versions.

  • D2K to OA Framework Transition

    - by PRajkumar
    What is the difference between D2K form and OA Framework? It is a very innocent but important question for someone that desires to make transition from D2K to OA Framework. I hope you have already read and implemented OA Framework Getting Started. I will re-visit my own experience of implementing HelloWorld program in "OA Framework". When I implemented HelloWorld a year ago, I had no clue as to what I was doing & why I was doing those steps. I merely copied the steps from Oracle Tutorial without understanding them. Hence in this blog, I will try to explain in simple manner the meaning of OA Framework HelloWorld Program and compare the steps to D2K form [where possible]. To keep things simple, only basics will be discussed. Following key Steps were needed for HelloWorld Step 1 Create a new Workspace and a new Project as dictated by Oracle's tutorial. When defining project, you will specify a default package, which in this case was oracle.apps.ak.hello This means the following: - ak is the short name of the Application in Oracle           [means fnd_applications.short_name] hello is the name of your project Step 2 Next, you will create a OA Page within hello project Think OA Page as the fmx file itself in D2K. I am saying so because this page gets attached to the form function. This page will be created within hello project, hence the package name oracle.apps.ak.hello.webui Note the webui, it is a convention to have page in webui, means this page represents the Web User Interface You will assign the default AM [OAApplicationModule]. Think of AM "Connection Manager" and "Transaction State Manager" for your page          I can't co-relate this to anything in D2k, as there is no concept of Connection Pooling and that D2k is not stateless. Reason being that as soon as you kick off a D2K Form, it connects to a single session of Oracle and sticks to that single Oracle database session. So is not the case in OAF, hence AM is needed. Step 3 You create Region within the Page. ·         Region is what will store your fields. Text input fields will be of type messageTextInput. Think of Canvas in D2K. You can have nested regions. Stacked Canvas in D2K comes the closest to this component of OA Framework Step 4 Add a button to one of the nested regions The itemStyle should be submitButton, in case you want the page to be submitted when this button is clicked There is no WHEN-BUTTON-PRESSED trigger in OAF. In Framework, you will add a controller java code to handle events like Form Submit button clicks. JDeveloper generates the default code for you. Primarily two functions [should I call methods] will be created processRequest [for UI Rendering Handling] and processFormRequest          Think of processRequest as WHEN-NEW-FORM-INSTANCE, though processRequest is very restrictive. Note What is the difference between processRequest and processFormRequest? These two methods are available in the Default Controller class that gets created. processFormRequest This method is commonly used to react/respond to the event that has taken place, for example click of a button. Some examples are if(oapagecontext.getParameter("Cancel") != null) (Do your processing for Cancellation/ Rollback) if(oapagecontext.getParameter("Submit") != null) (Do your validations and commit here) if(oapagecontext.getParameter("Update") != null) (Do your validations and commit here) In the above three examples, you could be calling oapagecontext.forwardImmediately to re-direct the page navigation to some other page if needed. processRequest In this method, usually page rendering related code is written. Effectively, each GUI component is a bean that gets initialised during processRequest. Those who are familiar with D2K forms, something like pre-query may be written in this method. Step 5 In the controller to access the value in field "HelloName" the command is String userContent = pageContext.getParameter("HelloName"); In D2k, we used :block.field. In OAFramework, at submission of page, all the field values get passed into to OAPageContext object. Use getParameter to access the field value To set the value of the field, use OAMessageTextInputBean field HelloName = (OAMessageTextInputBean)webBean.findChildRecursive("HelloName"); fieldHelloName.setText(pageContext,"Setting the default value" ); Note when setting field value in controller: Note 1. Do not set the value in processFormRequest Note 2. If the field comes from View Object, then do not use setText in controller Note 3. For control fields [that are not based on View Objects], you can use setText to assign values in processRequest method Lets take some notes to expand beyond the HelloWorld Project Note 1 In D2K-forms we sort of created a Window, attached to Canvas, and then fields within that Canvas. However in OA Framework, think of Page being fmx/Window, think of Region being a Canvas, and fields being within Regions. This is not a formal/accurate understanding of analogy between D2k and Framework, but is close to being logical. Note 2 In D2k, your Forms fmb file was compiled to fmx. It was fmx file that was deployed on mid-tier. In case of OAF, your OA Page is nothing but a XML file. We call this MDS [meta data]. Whatever name you give to "Page" in OAF, an XML file of the same name gets created. This xml file must then be loaded into database by using XML Importer command. Note 3 Apart from MDS XML file, almost everything else is merely deployed to your mid-tier. Usually this is underneath $JAVA_TOP/oracle/apps/../.. All java files will go underneath java top/oracle/apps/../.. etc. Note 4 When building tutorial, ignore the steps for setting "Attribute Sets". These are not mandatory. Oracle might just have developed their tutorials without including these. Think of these like Visual Attributes of D2K forms Note 5 Controller is where you will write any java code in OA Framework. You can create a Controller per Page or have a different Controller for each of the Regions with the same Page. Note 6 In the method processFormRequest of the Controller, you can access the values of the page by using notation pageContext.getParameter("<fieldname here>"). This method processFormRequest is executed when the OAF Screen/Page is submitted by click of a button. Note 7 Inside the controller, all the Database Related interactions for example interaction with View Objects happen via Application Module. But why so? Because Application Module Manages the transaction state of the Application. OAApplicationModuleImpl oaapplicationmoduleimpl = OAApplicationModuleImpl)oapagecontext.getApplicationModule(oawebbean); OADBTransaction oadbtransaction = OADBTransaction)oaapplicationmoduleimpl.getDBTransaction(); Note 8 In D2K, we have control block or a block based on database view. Similarly, in OA Framework, if the field does not have view Object attached, then it is like a control field. Hence in HelloWorld example, field HelloName is a control field [in D2K terminology]. A view Object can either be based on a view/table, synonym or on a SQL statement. Note 9 I wish to access the fields in multi record block that is based on view Object. Can I do this in Controller? Sure you can. To traverse through those records, do the below ·         Get the reference to the View Object using (OAViewObject)oapagecontext.getApplicationModule(oawebbean).findViewObject("VO Name Here") ·         Loop through the records in View Objects using count returned from oaviewobject.getFetchedRowCount() ·         For each record, fetch the value of the fields within the loop as oracle.jbo.Row row = oaviewobject.getRowAtRangeIndex(loop index here); (String)row.getAttribute("Column name of VO here ");
