Forms 6i con Servlets

Tenemos una aplicacion web en modo CGI, queremos pasarla a
SERVLETS. Necesitamos ayuda al respecto.

The combination is not supported, but it could work installing patch 17 (or 18). What exact patch version is your Forms 6i ?
If you already are on patch 17 or 18, please post sqlnet.ora and tnsnames.ora files from Forms machine (in ORACLE_HOME\network\admin), and the result, on database machine, of

Buttons in HTML Forms attached to servlets

Hi,
This seems like it should be a simple thing to me, but I haven't done enough html (or maybe it's enough servlets) to know what to do here.
I have a section of my webpage that is entirely servlet-based. On one page (created by a servlet), I have a form. I'd like to put two buttons on the bottom of this form and be able to distinguish which one was pushed. The form sends to another servlet and I am getting other data out of the form in that servlet. (Text fields, which is text input type, that show up in the requestParameters). I tried the following:
out.println( "<input type=\"submit\" value=\"Button1\" name=\"button1\">" );
out.println( "<input type=\"submit\" value=\"Button2\" name=\"button2\">" );in the servlet that the form connects to, I tried the following:
String buttonOne = request.getParameter( "button1" );
String buttonTwo = request.getParamter( "button2" );
if(buttonOne != null)
System.out.println( buttonOne );
if(buttonTwo != null)
System.out.println( buttonTwo );
}But when I do this, nothing prints to the screen, so obviously it isn't right.
Anyways, if anyone could tell me a way I could tell which button was clicked, that's all I want!!!
Thanks for any help you might give!!

But when I do this, nothing prints to the screen, so obviously it isn't right.And don't expect System.out.println() in a servlet to print to any "screen". It certainly won't appear in the browser in response to your request; it should appear in one of your servlet container's log files. If it doesn't, then use the servlet log() method instead. Or just generate HTML containing your debugging output and send that back as the response.

Unable to access form parameter in servlet

What could be the possible reasons, If a server side program say a servlet, cannot access the request parameters.
I mean, i have a form and it uses get method. Now on submitting the form, I can see the query string in url but unable to access the same in servlet.
thank you all
Ravi

The most obvious reason might be that the servlet's
programmer wrote crappy code.
Show the code where you try to read the parameters,
please.Code is simple. To retrieve the form parameter I used the same
request.getParameter("paramname")
And in the form method used is get. After submission of form, I can see the form parameter appended to url
something like this:
http://localhost/servlets/Test?paramname=somevalue
But for somereason in servlet i.e at request.getParameter("paramname"), is hanging here.
I checked the paramname, no spelling mistakes as well :)
But i am not able to find out the reason why I am not able to get the paramname in servlet.
thanks

Help!!!!!using multiple submit form in java servlet

I am trying to build a application where i have 2 submit buttons. This is what i want to do. This code is in html
<html>
<head>
<script language="JavaScript">
function altSubmit() {
document.MyForm.action = "Second.html";
</script>
</head>
<body>
<form name="MyForm" method="post" action="First.html">
<input type="submit" value="Default Submit">
<input type="submit" value="Alternative Submit" onclick="altSubmit()">
</form>
</body>
</html>
I want to do the same in java servlet, but if i click on any of the buttons it goes to first.html, Can anyone help me. I think i am doing wrong with the javascript code. Can anyone show me how to do this. Please

out.println("<html>");
out.println("<head>");
out.println("<script language=\"JavaScript\">");
out.println("function altSubmit() {");
out.println("document.MyForm.action = \"Second.html\";");
out.println("document.MyForm.submit();");
out.println("}");
out.println("</script>");
out.println("</head>");
out.println("<body>");
My personal suggestion is to use follow the MVC (Model View Control) pattern where in you can write all your "html" part in a JSP.
Model -> Bean
View -> JSP
Control -> Servlet

Syntax for invoking servlet from form in a servlet context

          Hi all,
          I have a web application called A, put all related files in a directory B. I deployed
          some JSPs into a directory C under B. Within a jsp called c.jsp in C, a servlet
          is called in a form. What syntax should I use to call the servlet properly. For
          the given web application A, the url syntax for it is http://server/A/C/c.jsp.
          I used 'action=servlet', 'action=/servlet', but failed. For 'action=servlet',
          the user is directed to http://server/A/C/servlet. The other is http://server/servlet.
          Both are not correct. Any ideas?
          Thanks,
          Lijun


What is the servlet-mapping in the web.xml file? If this is your servlet mapping:
          <servlet>
          <servlet-name>CookieCounter</servlet-name>
          <servlet-class>examples.servlets.CookieCounter</servlet-class>
          </servlet>
          <servlet-mapping>
          <servlet-name>CookieCounter</servlet-name>
          <url-pattern>monster</url-pattern>
          </servlet-mapping>
          Then the appropriate action is action=monster (or possibly action=../monster).
          Hope this helps,
          Robert

Passing many form fields to servlet

Hi all,
In my web application I need to populate a class with form values.
From inside a JSP, it's quite easy:
<jsp:useBean id="beanId" class="myClass" />
<jsp:setProperty name="beanId" property="*"/>And the values are set automatically.
Can use something similar to get form fields from inside a servlet? How can I have a bean instantiated with form values?
Thanks!

Not in the standard API, no.
However the [url http://jakarta.apache.org/commons/beanutils/]Jakarta commons beanutils provides some handy utilities to do just this.
Specifically the method BeanUtils.populate(Object bean, Map properties) will do what you are after - and IMO better than the standard JSP setProperty tag, because it won't treat empty string as if the parameter wasn't there.

How to post a form to a servlet in CQ5.5?

Hi all,
I'm using CQ5 to develop some things. and now i am not so clearly how to post a 'FORM' and accept with a SERVLET.
I've seen this 'http://forums.adobe.com/message/4932739#4932739' already, and try it. But once i add a new <input /> like :<input name="age" value="age" />.
and i submit this form, then tell me error: javax.jcr.nodetype.ConstraintViolationException: no matching property definition found for {}age
see the code
   jsp:
     
    <form id="submitForm" method="post" action="<%= action %>.POST.html" onsubmit="return validate();">
        <input type="hidden" name=":redirect" value="<%=resourceResolver.map(action)%>" />
        <input type="hidden" name=":formpath" value="<%=currentNode.getPath()%>" />
        <input type="hidden" name=":formtype" value="<%=component.getResourceType()%>" />
        <input type="hidden" name="_charset_" value="utf-8" />
        <input name="age" value="26" /> 
        <input type="submit" value="Submit"/>
    </form>
servlet:
    @Component(immediate = true, metatype = false, label = "QuestionnaireServlet")
   @Service
   @Properties(value = {
                    @org.apache.felix.scr.annotations.Property(name = "sling.servlet.methods", value = { "POST" }),

   public class QuestionnaireServlet extends SlingAllMethodsServlet implements
                    OptingServlet {
    protected void doPost(SlingHttpServletRequest request,
                              SlingHttpServletResponse response) throws ServletException,
                              IOException {
          //it seems never call this function.
can anybody told me in details ?

1).open the system/console/bundles and i can see the information of my servlet. include 'Symbolic Name', Version, Bundle Location, Exported Packages and so on. I think it already a service. right ?
2). change the selector to QAPOST for sling.servlet.selectors
3). add the slash "/" then submit and the browser show me "403 Forbidden"
4). without slash "/" before <action_attr_value>.POST.html, show me 'Status: 500', Message: javax.jcr.nodetype.ConstraintViolationException: no matching property definition found for {}age

Validating HTML form generated by servlet

Hi, folks. I have a dynamic html form generated by a servlet class. Once user fills up the form and submits it, i have another servlet does the form validation. My question is how can i reload the generated html form with error messages when user's inputs failed validation?
I am not able to use JavaScript pop-up windows for doing validation cause the page will be displayed on PDA and cell phone as well. Any help is greatly appreciated.

Could you combine the servlets.
I'm not sure but then you may be able to have the generator servlet in the doGet method and the validator in the doPost method. (don't quote me on this)
If you combine the servlets you have access to the original data (the form), that way if any validation errors occur you can repost the form with their entered data and an error message.

I want to create a login form by using servlets with database validation.

Would you please provide me a code for a login form using servlets with Ms Access database validation?

No. This is not a free coding service. Your request is (a) ridiculous, (b) offensive, and (c) off-topic. Locking this thread for later deletion.

Can I send values to an Oracle Developer 6i Form from a servlet

I have a Developer Forms 6i application where I launch a servlet which opens a socket to another IP address. The servlet needs to send status messages back to the Developer 6i form. Is this possible? Can the servlet communicate with the form? Remember that the form is served via the applet viewer in the browser. Thanks

You can find an answer for a similar question here:
http://stackoverflow.com/questions/1859248/how-to-change-time-in-datetime
The point is DateTime is immutable, thus you cannot change it.
DateTime StartDateTime = DateTime.Now;
int hour = 5;
int minute = 45;
// hour, minute, second
TimeSpan ts = new TimeSpan(hour, minute, 0);
StartDateTime = StartDateTime.Date.Add(ts);

How to stablish a bidirectional conversation beetween forms 10g and servlet

Hello I am investigating how to stablish a bidirectional conversation beetween forms 10g and a servlet. We want to make an application in Java that calls forms but we want that global variables send their values to forms and forms send values to java application.
If any one can help me with a tutorial o guide.
Best Regards,
Paola

It is possible to call out to Java from Forms starting with Forms 9i.
It is not yet possible to call back into Forms from Java though. That will probably come in v11.
You could potentially make a JavaBean that connects to your Java code thru sockets or some other method and place it in the form. That support also came in 9i.

Importing data to a pdf form from a servlet

I have a pdf form that pops up a browser window. This window is where the user does a lot of pre-emptive mainframe calls to collect some needed information to be returned to the form.
My questions are:
Is there a way to reference the data that is embedded in the browser window?
Could I embed the data as javascript variables?
I have heard of maybe the solution could come through the use of a hidden applet?
By doing it this way we won't have to build a bunch complex form to do all these calls...
Thanks for your input!

If you created the form Go back to Acroabt and go to advanced menu and choose:
Extend Features in Reader. then save.
Now open Reader and you can add information and save. (limit 500 instances per pdf).
Now if you created the form and have Acrobat make sure Acrobat in not in Forms Edit Mode.
Just type in your information and save.
Caution make sure that you finished all corrections and edits. because once you confer reader right you can not edit the form. you can edit the form items you fill in, but not the form itself.
to correct the form design you have to go back to advanced reader rights and save a copy without rights. make changes then confer rights again.

Maintain session when calling servlet from form in a JSP

I have the following set up:
index.jsp calls login servlet from the action tag in a form.
Login servlet handles the login, stores the user info and db connection in the session and uses forward(req,res) to call another jsp.
That jsp has a form where user enters search info and in that form's action tag there is a search servlet. In the search servlet I am unable to access the session.
Is there any way to pass the session to the servlet from that jsp using a form/action?

I've read elsewhere that if you go from a jsp to a servlet that the >request object is cleared of any attributes from the previous request.which is correct. But arent we speaking about session object here? A request object is valid for a request - ie the phase from where the server receieves a hit for a resource upto the point it sends the output for that request.
A session spans multiple requests.
it doesn't retrieve the session info and gives me a null pointer >exception when I try to use the connection object stored in the session.Bad bad bad . Why do you store Connection objects in session? Create them when necessary or use a connection pool. Do you for example clean up the connections when the session expires. What if its a 30 minute session and the user hits every say 15 minutes with a request. Why do you need to hold on to the Connection in the intervening interval when the user's session is inactive?
gives me a null pointer exception when I try to use the connection object stored in the session.which means that the Connection object is null - not the session object.
That last line is where I get the null pointer exception. And that is
Statement stmt = con.createStatement();?
Same answer as above.
If the session object was null,
userSession.getAttribute("connection");would have thrown a NPE.
