Passing values to servlet

HI All
I am developing a project using html and servlets. from my html page(regis.html) i am trying to pass the values which are entered by the user to the servlet (Admin_Regis.java) which is in the another package called Admin. The way i am doing is
<form class="registerlogin" method="post" action="Adimn/Admin_Regis">
but i am not able to send the values to the servlet. It showsr HTTP Status 404 - /Adimn/Admin_Regis.
My question is how to pass the values from html to servlet which is the different packages . I have three more packages .
Can any body please help me in solving this problem.

HI
The problem i was facing ie the values was not able to pass to the servlet i got the part of the solution for that . What actually i have done is i have kept all my web pages in one saperate folder so i was not able to send . But now when all my pages are in default folder even then i was not be send the values can any body please help me out for this problem.

Best way to pass values btwn servlets?

i have to pass multiple values from one servlet to the next, when the user submits a form.
i don't know how many, or even the names of the parameters until the user submits the form.
right now, i send them as hidden fields when the form is submitted.
in the receiveing servlet, i dump them into a hashtable usng httpUtils.parse QueryString, and then parse them out of the hashtable.
is there a better way?
TIA,
Scott Murray

DrClap,
Yes, I am working with a single user.
Last night I reworked it as follows, dumping the parameters into a Properties object, which is easier to work with than a hashtable (at least it is for me):
Properties props = new Properties();
Enumeration paramNames = req.getParameterNames();
while (paramNames.hasMoreElements()) {
String name = (String) paramNames.nextElement();
String[] values = req.getParameterValues(name);
props.setProperty (name, values[0]);
The trick is that I don't know in advance the names or how many parameters are being received; I marked them on the sending page with different prefixes (@@@, ###, $$$) so as I parse thru the Properties object, I can determine what type of parameter it is.
Is there a better object to use than the Properties object? My ultimate goal is to have something similar to a ResultSet that I can search and step thru multiple times.
Thanks for you time and expertise,
Scott Murray

Passing value from Servlet to JSP back to Servlet

Hi all,
I have a jsp page where a user submits a search string into a text box. The jsp forwards to a servlet which calls some java classes and checks a database. The classes generate a string which contains some html. The servlet then forwards back to the jsp which displays the the string:
<c:out escapeXml="false" value="${requestScope.ampList}" />The user then performs another action on this outputted html which is a listbox and when the user clicks on the listbox the onchange method submits the form. The JSP forwards the listbox value and I would like it to forward the "ampList" as well but I cant figure out how to do this.
Using a hidden input does not work because the string contains HTML. Does anyone have any ideas. I can just keep the search string stored a hidden input box but I would prefer not to regenerate the "ampList" as it means accessing the database again which will cause performance issues.
Thanks for any input in advance,
Tom

Ha,
Writing that message gave me an idea which worked:
<input type="hidden" name="ampList" value="<c:out escapeXml="true" value="${requestScope.ampList}" />" />

Null values passed into the servlet

Hi all,
I keep getting null values for all the params that I pass into the servlet i.e. sqltype, producttype, process, instance etc....I have attempted to print some of them out on the screen but I keep getting the 'NullPointerException' error message...can anyone tell me what it is that I have down wrong in the below code?
If I run the servlet with method calls that have hardcoded arguments in them it works but not when I pass in the params from the URL...I am absolutley puzzled!

     public String getServletInfo()
     return this.getClass().getName();
}

That section of the code references a cache to extract an item that has been requested by the user. If the item is not in the cache i.e. if(o1 == null) then it will call a class that generates that object and places that object into the cache. The second time the user makes the same call then they will be handed a cached copy of that object which is aimed to make the whole servlet call faster.
That section of the code works fine coz I have tested that separately. It is the reading in of the arguments that is causing the problem.

Servlet passing values to JSP and ClasscastException

I am using weblogic 5.1 to run my Servlets.
          I want to know when I forward from a servlet to a JSP how do I pass
          values especially Java Objects (Sometimes Objects of User written Java
          classes).
          Uptil now I have been putting all values in the session from where the
          JSP picks them up, but somehow I have a feeling that this is not the
          right way.
          In a code I am putting a Java Object (It contains two attributes of
          Java.util.Vector type) in the session so that the JSP to which I am
          forwarding it to can use it I have put my class in the ServletClasses.
          Intertestingly it runs well till the contents of the Vector are changed.
          As the contents of the vector are changed, it throws ClassCastException
          The StackTrace is as follows:

Only can confirm your finding - the jsp is using a different class loader to the servlet that originally instantiated the object. There's the rub. I haven't figured out yet how to fix that. I can get the classloader but don't know how to get the runtime to use that class loader to perform cast.

          Suppose my servlet is forwarding to a jsp . What should it do in case an
          exception happens in the servlet and wants to forward it to the jsp.
          Putting the Exception object in the session is an alternative but I
          wonder that is the best approach.
          If someone knows a better way od doing it, please help.

You could probably use setAttribute
          ..before forwarding the control to JSP.
          req.setAttribute("message", "Hello, world");
          ServletContext app = getServletContext();
          RequestDispatcher disp;
          disp = app.getRequestDispatcher("Dispmessage.jsp");
          Cheers,

HOW TO PASS VALUE TO STORED PROCEDURE through page

Hi
I want to create generate next number on base of type. I have created stored procedure with passing three value input. If I am passing value manually through page then next number is generating. But I don't to pass value manually, I have to assign value internally as per database record.
Sameh Nassar: Create PL/SQL Function And Call It From Your ADF Application
I did same thing in my application,It is working,Output like that
Value = INV
Result= 26400080
Now I have to assign value TRANSCATION TYPE through bean class or assign another textbox value. I did in my program in the following ways
   <af:inputText value="INV"
                                                          label="#{bindings.p_transaction_type.hints.label}"
                                                          required="#{bindings.p_transaction_type.hints.mandatory}"
                                                          columns="#{bindings.p_transaction_type.hints.displayWidth}"
                                                          maximumLength="#{bindings.p_transaction_type.hints.precision}"
                                                          shortDesc="#{bindings.p_transaction_type.hints.tooltip}"
                                                          id="it16" binding="#{InvoiceJobOrderBean.transacation_type}"
                                                          partialTriggers="it16">
                                                <f:validator binding="#{bindings.p_transaction_type.validator}"/>
                                            </af:inputText>
then I got the following error.

hi user,
please don't continue your discussion on others thread.
https://forums.oracle.com/thread/369112
it will be treated as hijacking. Admin will lock out the thread. and your problem is contrary to the thread.
coming to your problem,
did you ever get a chance to read the error it is self explanatory. or else goggle it out to understand.
It is not operation binding problem. while invoking the operation binding you are calling some db function from there you caught.
coming to your requirement,
create generate next number on base of type. please check will multi user environment it working properly or not.

How to pass parameters to servlet with POST with Business Service OSB

Hi all.
I am newby in OSB. I am trying to send some values through a POST call to a servlet. I know how to call the servlet with Business Service of type "Messaging Service". I send the parameters of type Text.
I have tried several ways, but I don`t find the proper way yo do it. I have tried to insert the param into the body and into the header.
The problem is that I don`t know exactly where to put them, I don`t know if it must be done in the header or in the boy. I neither don`t know if there is a common way to do this.
Please, could you give me a good example of an insert activity to isert a post parameter inside the call?
For example: now I am using this one:
Expression => "accountType=test"
Location => as first child of"
XPATH => empty.
In variable => body.
Where do I have to insert this, in the body or in the outbounds?
I have followed this posts:
https://blogs.oracle.com/jeffdavies/entry/enhanced_rest_support_in_oracl
http://www.yenlo.nl/en/using-osb-with-rest/
Thanks a lot.

Hi,
Please be carefull about passing values such as Strings or number that contains ',' .
using the way described above.
the best way is to pass an ID and then use a select Statement to get the other Values in the target page.
regards
MDK.

JSP Custom Tags, Tag Handlers, Passing values

Multiple questions here while I try to work with custom tags (its a requirement):
From what I have had so far - I have a .tld file, a .java file and a .jsp page.
(this is not a working version as I just got it from a website)
platform: tomcat on an xp box.
I was wondering if we can pass the parameters that are passed to the the jsp page (like blah.jsp?param1=value1&param2=valu2 ) to the tag handler?
This is because the processing that I need to do in the handler would depend on what I have in the passed values.
Any help in letting me know where to place those files on the tomcat context root would help. Please see, I do have a couple of servlets running on the box also and they might be in the same context root.
Any good short tutorial link is also welcome as a short answer as I try to unravel the custom tags in jsp.

I am using TomCat 5.5
What I need to do using tags is to build a web-page on the fly by polling a couple of different tables in the database.
This is to be done using a jsp and custom tag (requirement) which would be able to handle any resultsets. We also have to come up with pageContext attribute names and supply column names as those attributes. Thus we will have to come up with the meta data file and a tag library descriptor as well.
I found a helloworld solution on a website and was trying to modify it to meet my needs. But I guess I under-estimated the work that needed to be done in this one.

How to Pass values from XML to JSP??? Urgent Please Help me

Hi guys,
I am new to XML, I want to pass values from XML to JSP. I have a xml file with attributes, I should send this values to a JSP file. How is it??? Please Help guys.... its very urgent. Please send me how to do it with an example or atleast any urls related that....
Looking for ur favourable reply.
Thanks in advance,
Sridhar

in a servlet :
parse your xml file (see how at the end of the post) and
put the values you want in the request attributes
request.setAttribute("value1", value1);
...redirect to the jsp
in the JSP:
get the wanted attributes:
String value1=(String)request.getAttribute("value1");To learn how to parse a xml file, pay a look at this page, it explains how to read the XML document to build an object representation, and then how to navigate through this object to get the data

Pass data from servlet to jsp using sendRedirect

Hi,
I am passing data from servlet to jsp using forward method of request dispatcher but as it doesn't change the url it is creating problems. When ever user refreshes the screen(browser refresh) it's re-loading both servlet and jsp, which i don't want to happen. I want only the jsp to be reloaded.
Can I pass data from servlet to jsp using sendRedirect in this case. I also want to pass some values from servlet to jsp but without using query string. I want to set some attributes and send to jsp just like we do for forward method of request dispatcher.
Is there any way i can send data using attributes(without using query string) using sendRedirect? Please let me know

sendRedirect is meant as a true redirect. meaning
you can use it to redirect to urls not in your
context....with forward you couldn't pass information
to jsps/servlets outside your own context.Actually, you can:
getServletContext().getContext("/other").getRequestDispatcher("/path/to/servlet").forward(request, response)I think the issue here is that the OP would like to have RequestDispatcher.forward() also update the address in the client's browser. That's not possible, AFAIK. By the time the request is forwarded, the browser has already determined the URL of the servlet, and the only I know of way to have the browser change the URL to the forwarded Servlet/JSP is to send a Location: header (i.e. sendRedirect()). Remember that server-side dispatching is transparent to the client. Maybe there's some tricky stuff you can do with JavaScript to change the address in the address bar without reloading the page?

Pass value to an application ...

hi Gurus,
Is it possible to pass values to an external application using java code.[ no JSPs and servlets involved ]
Guide me!!!
Regards,
-Nags

Yes. Use the Runtime and Process classes:
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Process.html
An example for listing a directory on a UNIX platform:
import java.io.*;
public class Test {
    public static void main(String[] args) throws Exception {
        Runtime runtime = Runtime.getRuntime();
        Process process = runtime.exec(new String[] { "ls", "-alF", args[0] });
        process.waitFor();
        BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
        for (String s = br.readLine(); s != null; s = br.readLine()) {
            System.out.println(s);
}This simple code does not check for exit codes, or error messages.
Cheers, Neil

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);

Background Job pass value

Hi, I am calling a Background job in my program. I am using JOB_OPEN, JOB_SUBMIT and JOB_CLOSE FM to start a job. My need is to pass a value to the job program(job program doesnt have any selection screen values). Is their any way without creating variants each time to pass value to it.
Please advice.....

Hello,
You can first use JOB_OPEN which returns job number. Then build ranges or parameters to use SUBMIT to call the program.
Eg: SUBMIT RM06BB20 AND RETURN
      WITH S_EKGRP IN R_EKGRP
      WITH S_EKORG IN R_EKORG
      WITH S_FLIEF IN R_FLIEF
      WITH S_KONNR IN R_KONNR
      USER sy-uname VIA JOB w_jobname
      NUMBER w_job_number.
Now use JOB_CLOSE.
Thanks,
Venu
