Cannot pass parameter to servlet

dear all,
I am writing a MIDlet to post some data to a servlet.At the MIDlet, i set as below:
String url = getAppProperty("Login.URL");
conn = (HttpConnection)Connector.open(url);
conn.setRequestMethod(HttpConnection.POST);
conn.setRequestProperty("User-Agent", "Profile/MIDP-1.0 Configuration/CLDC-1.0");
conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
conn.setRequestProperty("Accept", "application/octet-stream" );
conn.setRequestProperty("Connection", "close" );
os = conn.openOutputStream();
byte data [] = ("userid="+userid.getString()).getBytes();
os.write(data);
data = ("&password="+password.getString()).getBytes();
os.write(data);
os.flush();
At the servlet, I coded:
String id = request.getParameter("userid"),
pass = request.getParameter("password");
When i posted "userid=123&password=123" to the servlet, the servlet directed me to 'LoginFail.jsp' with below output:
Login fail!
null //should be print out userid and password value
can anyone please give me some suggestions, why the servlet cannot locate parameter and how to solve it?
thanx a lot!

<p>I've done some similar program. I'm not sure why request.getParameter() won't return the value we past. However, I managed to resolve the problem with the following way:</p>
<p>Remain your MIDlet code. But change your servlets to use the following rather request.getParameter()</p>
<pre>
ServletInputStream sis = request.getInputStream();
DataInputStream din = new DataInputStream(sis);
String id = din.getUTF();
String pass = din.getUTF();
</pre>
<p>Good luck!</p>

Passing parameter from servlet to Javascript url

Hi all,
I want to pass the value of a selected option box in servlet as a parameter to a url in JavaScript.
my java script code is :
out.println("function reloadform() { ");
out.println("alert('aacat');");
out.println("location.href = 'http://localhost:8080/examples/servlet/frec1?aacatt=aacat';");
out.println("}");
and servlet code is :
out.println("<td bgcolor=#F2F9FF> <select name=aacat size=1 style=font-size: 8pt; color: #666666; font-family: Verdana; border: 1 solid #666666 onChange= 'reloadform();'>");
while (ra.next()==true) {
String mycat=ra.getString("acat");
String myasc=ra.getString("ascode");
out.println(mycat+"<br>");
out.println("<option value='"+mycat+"'><font face=verdana size=1>"+mycat+"</font></option>");
Can anyone suggest me something on this ? Any Code reference will be highly appreciated.
Thanks for any help in advance.
savdeep.

Please take care post the code in proper format...
regarding the solution.. try something like..
<select name=aacat size=1 style=font-size: 8pt; color: #666666; font-family: Verdana; border: 1 solid #666666 onChange= 'reloadform(this.options[this.selectedIndex].value);'>");also change the javascript code suitably

To pass Parameter to Servlet

Hi,
I have one servlet HTML page which gets the input from the user andon submittingthe form one mroe servlet is called which validates and dependig user value it will form the SQL select.
Then I need to call Servlet which will generate an HTML page with the result set of the SQL.
My problem is that from the processing form I need to send parameters and I am calling the final servlet usign forwardRequest. I formed the query string in teh form name=value and send the final string.
I want to know whether they is any better way to achieve this.
Please help me out!!!

u can get parameters from the processing form using the HttpServletRequest.getParameter(String ..) method. once got into the first servlet on processing if u need to pass them onto the second servlet using the forward mechanism then u store these values into the HttpServletRequest.setAttribute(...) and using the getAttribute() methos can retrieve them in the other...

Passing parameter to servlet

I can get a parameter with the ServletRequest.getAttribute(...) right?
But how can I give the parameter to the servlet?
Is it something like http://.../servlet/framePack.frameBase?table=env ?

Yer confusing parameters with attributes.
Parameters are something that are submitted by a html form.
you should be using request.getParameter() to get those parameters.
can get a parameter with the ServletRequest.getAttribute(...) right?refer to above.
But how can I give the parameter to the servlet?There's nothing as setParameter(); It has to be given via form submission or by building an url of the form
http://host:8080/yourapp/yourservlet?param1=val1&param2=val2.... and in the servlet you can get the values by doing a getParameter( on the request.
Is it something like http://.../servlet/framePack.frameBase?table=env ?
refer to above.

Passing parameter from Servlet to javascript in JSP. Very Urgent - 5 jukes!

Well my servlet will retrieve questions from database.
Then the player will answer the question in the JSP and submit the answer to the servlet to process.
Each time an answer is submitted, or a "Next Question" button is clicked, the countdown time will restart.
And will reload the page with a new question.
So how can i do that?

Servlet to pass parameter to another servlet

Hi, I have a question. I have two servlets, servler A and servlet B. I wanna do this:
1)servlet A to pass a parameter to servlet B. No redirect is required.
2)servlet B to accept the parameter.
How do I do that?
Thanks

1)servlet A to pass a parameter to servlet B. No redirect is required.
2)servlet B to accept the parameter.I completely agree with what capitao suggested.
As U said tht u need not require a redirect functionality
U actually need to implement a proxy kind of mechanism in this case
You may also go by using HttpURLConnection Object to retrive the info by passing few parameters.
checkout an eq code down below
HttpURLConnection server = (HttpURLConnection)(new URL("http://<hostname>:<port>/servletC")).openConnection();
server.setRequestProperty("testParam","testParam");
InputStreamReader isr = new InputStreamReader( server.getInputStream() );
BufferedReader in = new BufferedReader( isr );
response.setContentType( "text/html" );
PrintWriter outStr = response.getWriter();
String line = "";
while((line = in.readLine()) != null) {
outStr.println( line );
}

Passing parameter value via href in a servlet to another servlet

Hi
I have this issue with passing a value from one servlet to another servlet. the situation is is this.
i have a servlet tstret.java which say..pulls out all the employee_id(s) from a table and displays it as hyperlinks( using the anchor tag.).
now when i click on the hyperlink say T001 , The control is passed to another servlet which pulls out all the info about employee id T001.
the problem i have is in the tstret.java servlet. i am passing the employee_id as a parameter in the href path itself as shown below.
out.println("<td ><a href=\"http://localhost:7000/servlets-examples/accept_requisition.html?id="+[u]rs.getString(1)[/u]+"\" ><em>"+rs.getString(1)+"</em></a></td>");now if you see the code i am trying to pass the employee_id by attaching it to a variable id and passing it with the url, it gives me a sql exception saying no data found .
if i pass a string say "rajiv" which i defined at the begining of code then i am able to pass it to the next servlet/html.
the full code is as follows
file : tstret.java
import java.io.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class tstret extends HttpServlet
     PrintWriter out;
     String[] employee_identity;

          try
          response.setContentType("text/html");
          out = response.getWriter();
          String session_name="SHOBA";//request.getParameter("session_name");
          out.println("<html><head><title> My Jobs </title></head>");
          out.println("<body bgColor=#ececec leftMargin=10>");

          Can some one help me and see if there is anything i missing or doing wrong.
thanks in advance

Try storing the id at the top of the loop, then using that for the URL and the link text, instead of calling rs.getString(1) twice:
while(rs.next())
    String emp_id = rs.getString(1);
    out.println(" <tr align=\"center\">");
    out.println("<td ><a href=\"accept_requisition.html?id="+emp_id+"\" ><em>"+emp_id+"</em></a></td>");
    out.println("</tr>");
    out.println("<br />");
}

The javascript makes the input field to be null and cannot pass variable to

Hi
I use the following code to check whether the upload file is in the right format extension.
However, once I use it and it cannot pass the variable to servlet and throw nullpointerexception.
How can I fix it?
<script language="JavaScript">
    extArray = new Array(".jpg", ".png", ".gif");
    function LimitAttach(form, file) {
    allowSubmit = false;
    if (!file) return;
    while (file.indexOf("\\") != -1)
    file = file.slice(file.indexOf("\\") + 1);
    ext = file.slice(file.indexOf(".")).toLowerCase();
    for (var i = 0; i < extArray.length; i++) {
    if (extArray[i] == ext) { allowSubmit = true; break; }
    if (allowSubmit) return true;
    else
    alert("Please only upload files that end in types: "
    + (extArray.join(" ")) + "\nPlease select a new "
    + "file to upload and submit again.");
    return false;
</script>
OnSubmit="return LimitAttach(this.form, this.form.myimage.value)"
servlet:
boolean isMultipart = ServletFileUpload.isMultipartContent(request);

the js works fine, just add id=myimage and it is ok
checking file type for uploading only image on client side

Issue on How to mimic Deski document from CMS to local machine, pass parameter, execute and save in a mutiple report format then store in a network drive.

Post Author: usaitconsultant
CA Forum: JAVA
Would you know if there's a way to mimic Deski
document from BOXI server(CMS) to local machine, pass parameter, execute and
save in a mutiple report format then store in a local drive or network
drive? Most examples and tutorials in BO XI R2 I've seen are scheduling while drilling report is for web intelligence only and not desktop intelligence. Please let me know your ideas. I would really appreciate your help. Thanks.

Hi Ted,
Thanks for the reply.The file is not available in the server. Though, I checked CMS and I found an instance in history tab and the status is failed with error below.
Error Message:
A variable prevented the data provider Query 1 with BANRRD30 from being refreshed. (DMA0008).When I checked my codes, I found out that the object Im using is for web intelligence data provider. However, I cannot find any documentation and example for passing parameter values in desktop intelligence data provider. Any idea on this? You think this is not suported by Report Engine SDK?Thanks.

How to get month value from custom calendar without passing parameter from SSRS in MDX query

Could you please throw some light to achieve below requirement?
I need to filter the data between two periods dynamically . The date calendar here works differently(ex:-Date 26-Aug-2014 will fall in period 7 which is last date and 27-Aug-2014 will fall in period 8 and it is first date of period 8),so I cannot go
with system date period/Month. Date Hierarchy is like YEAR,QUARTER,PERIOD ,WEEK and DAY.
I cannot use SSRS for passing parameter. Requirement is to extract last 2 period of data dynamically in Power Pivot with MDX.
Thanks Chandan

Hi Chandan,
You might try something like this
Tail(null:
Extract(
StrToMember("[FYDay].[DATE].&[ + cStr(Format(Now(),"yyyy-MM-ddT00:00:00")) + "]")
*[FYDay].[DateHierarchy].[Day]
,[FYDay].[DateHierarchy]).parent.parent
,2)
What it is doing is multiplying Day by the current date, which returns a set of one date with cardinality of (Date,Day). The Extract is pulling out just the datehierarchy Day. the the Tail() is getting it and the previous day.
Hope that helps,
Richard

Error while passing parameter in Oracle Jdeveloper

Hi All,
I was passed Crystal report viewer object From Servlet it is Running fine but one problem in that while passing parameter from that page to data base it is not supporting (The ok Button on page).
can any one tell me how to find Action Button (.Jsp page)
Because i am using .jsp page That was made in CR4E
in that i found only jsp code I have not get how to work Action of that button
Also another problem while making Viewer.jsp pge ..rpt-Crystal reports--->>Create Viewer Jsp->>Insert CrysatlReport viewer API code------->>>1.Connectparameterinthat report 2.connect the crystalreportPageViewer while makin this page i was running on Apache tomcat Server it is not displaying Anything only Displaying Blank Browser
Can Any one help me...
Sincerly
Amol

For your first question can you please be a little more clear as to what you are referring to? I am not familiar with an action button for the parameter pages.... what I can tell you is that we don't have any jsp code for the viewer controls, all of that is generated dynamically at runtime. We do have a viewer SDK that you can use to set properties on the viewer; information about this can be found in the [Developer Library|https://boc.sdn.sap.com/developer/library] in the Viewer SDK documentation book.
For your second question, I assume you are referring to generating a viewer page from a report in Crystal Reports for Eclipse. You will need to uncomment the viewer code (for some reason when the page is generated, the viewer code has block comments surrounding it). You will probably want to make sure the parameter code is uncommented as well.
In addition to this, there is a helper file called JRCHelperSample.java that contains all of the helper methods for the automatically generated viewer page. This can be modified in whatever way you wish to suit your needs.

How do I pass parameter to different portlet regions from another page?

How do I pass parameter to different portlet regions from
another page?
I have a page that with two regions. Each region has a report
that uses the same information to generate its report.
Individually running the reports, I can use p_arg_names and
p_arg_values to get what I want. However, when I run the page
that has both portlets, my .show is gone and I cannot get it to
use the p_arg_names, etc. Do you have any idea how to overcome
this? Thanks for any help.
