HTML forms and Servlets

Hi all.
This is the story:
I got a SELECT field that contains OPTIONS with values and labels (both different). How I do to get this two data.
With request.getParameter("menu1") i can get the VALUE, how i can get the Label?
Second quiestion:
I got a input checkbox type , this has a VALUE property, but In my servlet i just want to know if it's cheked or no.
If i do something like request.getParameter("check1")I get the VALUE data. how to tell if it is cheked??
Thanks in advance any help.

First Question:
The option value is what gets sent is when the form is submitted. If you want the information sent then you'll have to add it to the value and parse it out in the servlet.
Second Question:
Only checkboxes that are checked get sent when the form is submitted. If the parameter does not return null then the box was checked. If the box was not checked then the getParameter call will return null.

  • Images in HTML forms and/or reports

    Hi,
    Apologies if a stupid question, but can you display a combination of data and image content in Portal HTML forms and/or reports? If so, how?
    This question assumes that the image in question is browser-supported (e.g. gif file), and the link to it is in the same database table as the data being reported (as a bfile data type).
    Alternatively, what if the image was actually directly stored in the database table as a BLOB data type?
    Help!
    Cheers, Jeff

    Hi Sharmila,
    Thanks for the info!
    Would this also work if the image wasn't a blob, but instead just stored on the filesystem (as a gif file), with the reference to it stored in the database as a bfile datatype?
    Thanks once again, Jeff
    Hi,
    You can build portal forms to upload images. You can use blob columns here. You can also have images in a report. This will be the SQL to query data from tables having intermedia data.
    Select a.empno,a.ename,a.mgr,a.sal,
    portal30.wwv_user_utilities.get_intermedia('EMP','EMP_AUDIO','AUDIO',a.rowid)
    the_audio, b.dname,b.loc,
    portal30.wwv_user_utilities.get_intermedia('DEPT','DEPT_PICTURE','IMAGE',b.rowid) the_picture
    from emp a, dept b
    where a.deptno = b.deptno
    The table should have the ordimage column type.
    Thanks,
    Sharmila

  • HTML Forms and Procedures

    Hello!
    We are trying out APEX for the first time. We would like to keep our business data objects in a different schema from the APEX schema. I have been able to successfuly create a proc and create a form over the proc in the differenet schema.
    I'm wondering if we can create HTML forms and later reference the procedure. The goal is to have the Database Developers create the procs while the developers create the forms at their own pace, then later wire that form to the proc. I hope this makes sense!!
    Thx!

    I resolved this on my own. Pretty simple, just new at this.

  • HTML forms and tables w/Oracle

    Hi,
    New to Oracle - used AMP before.
    My new organization does not use any open source so PHP is out. I assume I could use .net or java instead to DB query from HTML forms and render DB results to HTML tables.
    But besides .net and java are there any other languages that work well with Oracle for this purpose?
    Thanks,

  • Uploading File To MySQL from HTML form via Servlet

    Hello all !
    I hope this is better place to ask.
    I'm working on simple Servlet/Jsp application trying to hold to MVC pattern and got stuck on uploading file to MySQL db.
    Here's what I'm trying to accomplish:
    1) client submits a JPEG image via a simple html form on a webpage.
    2) JPEG is put into a database table, column field of type BLOB.
    3) Servlet processes the request, gets a connection to the db and inserts the image into the table.
    4) after that user is able to retrieve an image from db and display it in JSP page.
    This is pretty much the same task Angela was trying to do here:
    http://forum.java.sun.com/thread.jspa?threadID=667597&messageID=3905449
    I could use her snippets if i knew what is what and decided to figure out this myself. Aftet some investigation i found out that i need to import org.apache.commons.fileupload.*;which i found here: http://jakarta.apache.org/commons/fileupload/
    what am i driving at ?
    -----------------------1-----------------------
    After first line of code
    boolean isPart = FileUpload.isMultipartContent(request);netBeans 5.5 beta2 with bundled Tomcat 5.5.17 underlines this with warning saying that
    org.apache.commons.fileupload.FileUploadBase
    has been depreceted
    is it a reason for concern ?
    -----------------------2-----------------------
    Is it actually good idea to store images in db as blob ?
    what about large ammounts of text ?
    thank you
    -Dominik

    is it a reason for concern ?Yes.
    You should take a look at the method in the documentation and find out exact reason for depricating it.
    If it is depricated becouse they going to remove it in the future you should use the new alternative method becouse if you use the old method your app will not work in the future releases of the API.
    If it is depricated becouse it is not safe to use the method you should clearly understand the risks involved in using the method and see if that can give you any trouble in your project.
    -----------------------2-----------------------
    Is it actually good idea to store images in db as
    blob ?I think that it is ths best option available when you want to store binary data
    what about large ammounts of text ?You can use clob columns.
    By the way when you store files in the database its better you put some extra columns to store the file name and file type(mime) becouse you cant directly detect those things later by just looking at the data of the file.

  • HTML form and java

    Hi,
    I have been pulling my hair out for the past week on this with no suces EVEN after forum searching, googling ..........
    Here is the problem:
    I have an HTML form of the following type and need to pass in a Javascript variable to the servlet called on hitting the submit button.
    <script>document.write('<form name="Test" method="get" onSubmit="return chkfields(this)" action="/servlet/NewServlet?ABC='+unescape(params["ABC"])+'">')</script>For debugging purposes, I have a document.write statement and I see it on the page right above that line and it does display it on the field. However this thing does not pass the varible to the servlet. I even tried replacing the unescape(params["ABC"]) with just the variable name used in the form as ABC and that did nto work either. Please suggest any other suggestions.

    test.html:
    <!DOCTYPE HTML PUBLIC "-//w3c//dtd html 4.0 transitional//en">
    <html>
    <head>
    <script language="JavaScript">
    function setHidden() {
      document.testForm.testInput.value = "test";
      return true;
    </script>
    </head>
    <body>
    <form method="post" name="testForm" action="test2.jsp" onSubmit="return setHidden()">
    <INPUT TYPE="hidden" NAME="testInput">
    <INPUT TYPE="submit" VALUE="submit">
    </form>
    </body>
    </html>test2.jsp:
    <html>
    </head>
    <body>
    <%
    out.println(request.getParameter("testInput"));
    %>
    </body>

  • Http Session combing HTML forms and List / Menu Components

    My problem is the following one... I have a .jsp page that includes a form with three List / Menu Components. I want my second List / Menu Component to be filled with data depending on the selection I have made to the first List / Menu Components. (Of course there is a MYSQL database behind). And I want the third List Menu Component to be filled with data depending on the selection I have made to the second one.

    Three options:
    1) use incredibly large javascript arrays to hold the data for the second and third lists and use onChange events in the first and second list to alter the list contents based on selection
    2) use ajax calls to fetch the data for the second and third list, still using javascript events to listen for selections.
    3) do a form submit on each selection and fill the lists server side.
    The third option is of course by far the easiest, but that will give you submits in between that you may not want. Ajax is a good solution to this problem in my opinion.

  • Can  Java be used to save content of HTML form to a file?

    We have an application that saves a pdf file to a location on our webserver. The file displays on the users machine in a browser window. I have created a link in the links bar of the browser window which launches a simple HTML page. This page allows the user to enter a number of fields and click 'SAVE'. This is where I am having the problem. I need the save button to firstly create a csv file on the webserver containing the details input by the user. I then need the pdf file saved to the web server with a new name and in the same location as the csv file. is there anyway to achieve this using Java or can anyone please point me in the right direction?
    Thanks

    <<Click on the SAVE button in an HTML <form> and the browser will perform an HTTP POST of the data to a URL. Make that URL point to a Java servlet and it can take that form data
    <<and write it to the webserver file system in any format you wish, including csv and pdf.
    agree with duffy. You can also use JSP and call a class method to handle whatever data you specify.

  • Using JSP, HTML Form for uploading image  in order to be saved into a db

    I have a HTML form and I am using <input type="file"> tag. The problem is that I don't know the Java code needed for the JSP page in order to get through the path and get the image(of course I refer to binary object). Below there is the html code
    <%@ page language="java" import="java.sql.*, java.awt.*, java.awt.Event, java.util.*, java.io.*, javax.servlet.*"%>
    <html>
    <head>
    </head>

    <div align="left"></div>
    <form action="action.jsp" method="POST" name="form"
    <h1>Add Data</h1>
    <table>
    <tr>
    <td>Name</td>
    <td><input type="text" name="Name" value="" /></td>
    </tr>
    <tr>
    <td>Last Name</td>
    <td><input type="text" name="lastname" value=""/></td>
    </tr>
    <tr>
    <td>Studies</td>
    <td><textarea name="studies" rows="4" cols="20" >
    </textarea>

    <td> <input type="submit" > </td>
    </tr>
    </table>
    </form>
    If you want to view the Personnel List click here<br>
    Go to index
    </body>
    </html>

    A JSP should not be involved in this. The browser will offer a way to specify a file, and the target of the form should be a servlet that can handle multipart uploads. JSPs should not process any input.

  • Font error in html produced by servlet

    I am writing a servlet that reads data from html form and displays the
    input data in html form for confirmation.
    The program uses japanese characters but when servlet shows the output
    it doesnt show the japanese characters..instead ??? are displayed.
    How can i solve this problem. Here's my code
    public class MosiKomi extends HttpServlet {

  • How to retrieve input data from a HTML form in the UTF-8 cha

    I encountered the following problem with a JWeb Application:

    All processing should be done in the UTF-8 character set.
    The problem is, that the form data retrieved by getURLParameter

  • HTML Forms in OHJ

    We would like to be able to link from our online documentation to our corporate website through our secure customer portal, giving users access to features like discussion lists, FAQ, and bug fixes. In order to do this, we need to have functioning HTML Forms and SSL connections. I haven't been able to get HTML forms to work. Is there a fix coming for this? What about SSL? Is that built into the ICE browser?
    Jeff Beal

    Unfortunately this is an issue with Android and it isn’t possible for us to fix it. As a workaround you can either:
    Display our credential dialog after the reader taps a button in your banner instead of trying to collect the username/password in the banner itself
    Use a full custom store and collect the information in that

  • Pre-populated PDF forms and form submission

    Ok, I must be blind or something, I've searched for answers to this question, and see unanswered posts around the web, and if there are answers, they don't help. Perhaps if someone can answer this, it will help many others as well:
    I've read about how FDF/XFDF (the older method) can be sent to the client side, which will open the specified PDF file (as specified using the "/F" flag in the FDF) and load the fields values also specified in the FDF (using the /FIELDS and /T flags, etc.). I was recently told that XFA is the new format, but reading the docs is not clear to me.
    QUESTION: What is the proper method to pre-populate the FIELDS of a PDF form (created using LiveCycle Designer, or Acrobat, or whatever) that gets sent to a client browser? Changes to this pre-populated data gets re-submited via an HTTP post button (or whatever) back to the server.
    Note: At the server backend, say using C# in Visual Studio 2005, I can simply read the posted HTML form and store the fields values into a database; However, I need to be able to pre-populate these PDF forms with selected patient names, etc., so that healthcare officials can complete them more easily BEFORE they get posted back to the server. These pre-populated fields (some of them anyhow) must STILL be editable (not flatten to static text or something).
    Thanks.

    From your description, is doesn't sound like it has anything to do with the virtual enviroment. It does sound like the forms simply need to be Reader-enabled. This allows Reader to save filled-in forms, which is necessary when you want to email them. If all of your users can use Reader 11, the forms do not need to be Reader-enabled since it is capable of saving non-enabled form. To enable a form in Acrobat 10, select: File > Save As > Reader Extended PDF > Enable Additional Features
