Send large string between servlets in different domain

Hi,
I need to send a large string from servlet in an web application to a
servlet in another web application. Those two application are in
different domains. I can't send the string as request parameter,
bacause string is too large. I can't send as request attribute either,
because attribute will lost during redirect to another domain.
Any solutions? Thanks for any help.

do set/getAttribute at the ServletContext level which is unique for a particular webapplication. from 1st application u can access the 2nd one using , getServletConfig().getServletContext().getContext("/uripath") which gives you the ServletContext handle of the other application and you can do getAttribute of this.

> May be silly for you, but i like to know,
Anybody (different provider/domain) can send mails through his mobile to my
mobile (different provider/domain). How it is possible ?
I send an e-mail to you. My mail reader contacts my e-mail server. The e-mail server sees that I'm from the same domain. It accepts my e-mail - it ignores (for now) what the recipient's domain are.
My domain's e-mail server looks at the recipient and sees your domain. It now attempts to contact your domain's e-mail server. If it fails, it sends me an e-mail telling me of that failure.
If it succeeds, it tells your e-mail server that it has an e-mail for you from me. Your e-mail server sees that the recipient is on its domain. It therefore accepts the e-mail and delivers it to your post box. Your e-mail server is not concerned about the originator (me and my domain) as the delivery is for someone on its domain.
Only when the recipient and sender are both "unknown" to the mail server, it will/should refuse to accept that e-mail and try to relay it between one and another domain.
Bottom line - when sending an e-mail the SMTP server expects that you are either on the same domain as it (in which case it is there to service you), or that you are delivering an e-mail for someone on its domain (that someone being serviced by the server).

Unable to send email to different domain by JavaMail

Hello,
I'm developing a servlet application by using using JavaMail 1.2 with JDK 1.3/Resin 1.2.
My application is hosted at an ASP. When I send email some addresses under my domain,
there is no problem. Emails are sent successfully. But, if I send emails to addresses under different domains, I get MessagingException in Transport.send(message) method.
My CGI scripts can successfully email messages to different domain.
thanks in advance...

There is a Java Mail forum where you could have asked this. However, if you had looked there you would have found this question asked several times a week. Your ASP doesn't allow its e-mail system to be used for relaying. Ask the ASP if you don't understand what that means.

Send portal screen parameters to one absolute url in a different domain

Hi Experts,
We have a requirement wherein we have to send some screen parameters of the portal application to one url which is in a different domain.
We are currently using Iframe UI element and binding the source property of the UI element to a string attribute wherein we have set the url and the parameters.
The portal application is a webdynpro java application. The only requirement is to send the screen parameters to one particular url and nothing else. We do not want to create any html files and moreover we also do not want to make Iframe ui element visible in our webdynpro application.
Can you please suggest how can I acheive this?
Thanks & Regards,
Anurag

you can add the portal parameters to the target application URL
target app : http://some.com/application.jsp&param1=myvalue&param2=value
read URL parameters in Dynpro:
WDWebContextAdapter.getWebContextAdapter().getRequestParameter("param1");
Lemme know your requirement passing to URL or getting portal params
Regards,
Nikhil

How to send a String to a Servlet using a HTTP POST

Well, I have designed a servlet that receives a HTTP POST, I was testing it using an HTML form to send (using POST) information, now, I have coded a Java App to send it a string, I don't know how to make the servlet recognize that info so it can make its work, I am posting both codes (Servlet & API) so anyone can guide me and tell me how and where to modify them
Servlet:
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.sql.*;
public class xmlwriter extends HttpServlet
public void service(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
ServletOutputStream salida = res.getOutputStream();
res.setContentType("text/HTML");
String cadena = req.getParameter("cadena");
File f1 = new File ("c:/salida.xml");
FileWriter out = new FileWriter(f1);
f1.createNewFile();
out.write(cadena);
out.close();
salida.println("OK");
Now, the JAVA API is:
import java.io.*;
import java.net.*;
public class HTTPSender {
public static void main(String[] args) throws Exception {
URL url1 = new URL
("http://localhost:8080/XMLSender/xmlwriter");//internal site
URLConnection UrlConnObj1 = url1.openConnection();
HttpURLConnection huc1 = (HttpURLConnection)UrlConnObj1;
huc1.setRequestMethod("POST");
huc1.setDoOutput(true);
huc1.setDoInput(true);
huc1.setUseCaches(false);
huc1.setDefaultUseCaches(false);
String cadena = ""
+ "<root>\n"
+ "<tlf>$TLF$</tlf>\n"
+ "<op>$OP$</op>\n"
+ "<sc>$SC$</sc>\n"
+ "<body>$BODY$</body>\n"
+ "</root>";
PrintWriter out = new PrintWriter(huc1.getOutputStream());
System.out.println("string="+cadena);
out.write(cadena);
out.close();
I'm a JAVA newbie, so, maybe I'm getting a bad idea of what I need to do, anyway, every (detailed) help is welcome. What my servlet should do (and it doesn't when I send the message through the API) is to write a file with the info received.

I'm not trying to send a string from a WEB Page, I'm tryring to send it using a JAVA program, I mean, using a HTTPSender, in fact, I already have made the code to do that:
import java.io.*;
import java.net.*;
public class HTTPSender {
public static void main(String[] args) throws Exception {
try {
String cadena = "Message to be written";
// Send data
URL url = new URL("http://localhost:8080/XMLSender/xmlwriter");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(cadena);
wr.flush();
// Get the response
BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
// Process line...
wr.close();
rd.close();
} catch (Exception e) {
And modified my servlet so it can receive anything:
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.sql.*;
public class xmlwriter extends HttpServlet
public void service(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
ServletOutputStream salida = res.getOutputStream();
res.setContentType("text/HTML");
String cadena = req.toString();
File f1 = new File ("c:/salida.xml");
FileWriter out = new FileWriter(f1);
f1.createNewFile();
out.write(cadena);
out.close();
salida.println("OK");
Now the problem is that, the servlet in fact DOES create the file, but....the file is empty, that means that no info is arriving to the servlet, why?, how should I send it then? I repeat FORGET about a Web Page Form, that is in the past and I don't need that.

Authentication needed after doing trust between two different domains.

Hi There,
I have a problem when i did the trust relationship between two different domains in two different forests ,,in the trust relationship steps all working two ways trust,with external trust,stub zone created on both domains and they are validated in both sides
,,my problem is with the objects it can't be retrieved from side and it can be from the other side . For instance :
NY domain can get the users and computers of 2012DC1
but 2012DC1 can't get the users and computers of NY
Date and time are the same,i am always getting this error
The session setup from computer '2012DC1' failed because the security database does not contain a trust account 'test.com.' referenced by the specified computer.
USER ACTION
If this is the first occurrence of this event for the specified computer and account, this may be a transient issue that doesn't require any action at this time. If this is a Read-Only Domain Controller and 'test.com.' is a legitimate machine account
for the computer '2012DC1' then '2012DC1' should be marked cacheable for this location if appropriate or otherwise ensure connectivity to a domain controller capable of servicing the request (for example a writable domain controller). Otherwise,
the following steps may be taken to resolve this problem:
If 'test.com.' is a legitimate machine account for the computer '2012DC1', then '2012DC1' should be rejoined to the domain.
If 'test.com.' is a legitimate interdomain trust account, then the trust should be recreated.
Otherwise, assuming that 'test.com.' is not a legitimate account, the following action should be taken on '2012DC1':
If '2012DC1' is a Domain Controller, then the trust associated with 'test.com.' should be deleted.
If '2012DC1' is not a Domain Controller, it should be disjoined from the domain.
Can you please help me in this error.
Thank You in advance.

Hello,
"The session setup from computer '2012DC1' failed because the security database does not contain a trust account 'test.com.' referenced by the specified computer. "
This belongs to the machine 2012Dc1 in test.com and not to the other domain from your trust. Seems for me that you mix the trust with the problems of the machine 2012DC1 in test.com.
In this error message 2012DC1 has lost the trust to its OWN domain and therefore you have to find the reason. How exactly was this machine installed?
Or was there a restore on that machine from not supported type of backup like image/clone/snapshot?

Send email to different domain using different address

hi
I want to set my exchange recipients have 2 email address.
1=[email protected] 2=[email protected]
1.how can I set this setting? (I know I can use something called policy but I don't know how can use that for exchange 2013; please tell me how can do this)
2.how can set my exchange server to send email to different domain with different account? (after question 1; my recipients has 2 email address (***@domain.com,
***@domain.co) I want my recipients when send email to "company.com" using domain.com address and for other domains using domain.co)
thanks

1. Add an accepted domain. Add the e-mail address to your e-mail address policy. Update the e-mail address policy.
2. http://www.ivasoft.biz/choosefrom2007.shtml This has been the traditional answer for Exchange 2010 and earlier. You might contact him to see if it works for Exchange 2013.
I don't know of a native way to do this except to create separate mailboxes for each address.

Sending e-mails between different SAP-Systems with SMTP

Hello,
I want to send e-mails between two different internal SAP-Systems. I already configured SMTP in both systems but ist not possible to send an e-mail from system A to system B. I've got following error message:
Cannot process message; no node determined for <sapuser>:
Thanks in advance & best regards,
Christoph

Hi Christoph,
but it is possible that the email for user from System B is also available in the system itself(transaction so01) and not only in his outlook inbox?
As the email is sent from System A. It will be available under SOST of system A.
As user in System B is receiving the email, it will be appearing in users inbox.
Check with Mail server administrator on where to enable SMTP relaying for IP address of SAP server.
Hope this helps.

Send an report to an account on different domain.

How can I authenticate the MARS when it sends an email to an account on different domain.
Our mail server requires authentication to send mail.
Thanks.

Hi Andrea,
It isn't MARS but your email server which needs to be configured. Post what flavor of email server software you are using and I bet somebody in the forum can assist.
Hope this helps.

ObjectStream communication between servlet and rich client

Hi,
I need to send multiple objects from a servlet to a rich client.
Is it possible to send 2 objects of different types at the same time - ie, a hashtable and a custom object by writing them one after another into the response's ObjectOutputStream?
Also, if I have two vectors containing different object types, say a Vector of Strings and a Vector of custom objects, how do I read the ObjectStream at the client end to get these two objects? Do I read two Vectors from the ObjectInputStream and then check the contained object using instanceOf?
In the above scenarios, is it better to wrap the entire set of objects with a serialized wrapper class and send that single object from the server to the client?
Please advice. Thanks in advance!

You can send any number of objects in a stream one after other. If they are in different types/classes then you have to be carefull when casting to the specific types at the other end becouse if you try to cast to wrong type you get a runtime exception.
Normally when you receive the objects you will know in advande (programming time) which vector comes first in the stream so you can treat them acordingly.
Since both of them are vectors you can cast them to vector references at the read end and can tread the elements of the first vectors as strings and the elements of the other vectors as something else provided that the client always send the string vector first.
Whether to make it a single object or ot is a design decision that you have to make. It it make sence to put those two vectors together(logically related) then its better to do so.

Passing a large string in URL

Hi
The scenario is as follows
There are two servers A and B on different locations. From Server A i want to send a request to a url on server B. The request contains a string parameter of very large value (more than 255 characters). The problem is that I cant use a get because of the restriction.
How can I do the above in a jsp page. The string is generated dynamically when the user clicks on a link and also contains special characters like (+%)
I know i need to encode the url. But how do i post to a url on a different server
It would be nice if i can get the complete code. Short of time and cant read much thrugh the docs :)
Thanks
Sairam

That depends, what type of field are you inserting the string into? What you need to do is check the size of the field and the length of the string. If the length exceeds the field size, then you either need to increase the field size or, if you know you will be generally inserting very large strings, change the field to a clob. Hope this helps.

Batch Script using System Varriable for Hostname and FQDN results in large space between

I have a batch script running on Windows 7 that I've created to help a physical computer, connect to his virtual cousin. Problem is when I try to make
it use the FQDN (required by the View Client) it puts a large space between the hostname and the domain.
Result
ECHO Connecting View Client to PREFIX-SERIAL .domain.comOR"C:\Program Files\VmWare\View.exe" -Args -serverURL PREFIX-SERIAL .domain.com
Our computers are named a combination of a prefix and the serial number. Our virtual computer names are the same, but with a different prefix. So my attempt was to make a connection
script, using the computer serial number. My Process:
Setting %serial% variable.
for /F "skip=1 tokens=*" %%b in ('wmic bios get serialnumber') do if not defined serial set serial=%%b
Set %hostname% variable.
set hostname=PREFIX-%serial%
Installation command line
"C:\Program Files\VmWare\View.exe" -Args -serverURL %hostname%.domain.com
That results in the output at the beginning of my post.
I've also tried
%hostname%.%userdomain%.com
PREFIX-%serial%.%userdomain%.com
PREFIX-%serial%.domain.com
SET FQDN=.domain.com
PREFIX-%serial%%FQDN%
%hostname%%FQDN%
I also tried carets and quotes on set commands without any improvement.
I'm sure I'm missing something simple here. Any advise?
There's no place like 127.0.0.1

Will something like this get you what you are looking for?
(gwmi win32_bios).SerialNumber+(gwmi WIN32_ComputerSystem).Domain
Or
$hostname=(gwmi win32_bios).SerialNumber+"."+(gwmi WIN32_ComputerSystem).Domain
Sorry just realized your looking to do this in a Batch file...so maybe something like this
@echo off
for /F "skip=1 delims=" %%j in ('powershell "[System.Net.Dns]::GetHostByName((hostname)).HostName"') do (
set Host=%%j
goto :DONE
:DONE
echo %HOST%

Exchange POST data between servlets?

Hello all
First of all, my apologies for my English. This is the first time writing to forum.
I�m new to java and I need a little help with servlets.
I have the servlets A, B and C.
Servlet A just display a page with a form tag witch send the data to Servlet C via POST method. What I want is to intercede the Servlet B between them and check the integrity of those POST data.
For example: Servlet A send data to Servlet B via POST method, Servlet B check the integrity of those data, and finally Servlet B send those data to Servlet C via POST method.
For now the only I have done is to send the data to B and transfer the data to C with GET method.
How can I send data with POST method in a servlet?
The code so far:
     String urlstr = new String();
     String str1 = request.getParameter("st_name");
String str2 = request.getParameter("st_birth");
String str3 = request.getParameter("st_class");
��some check ��
     urlstr = "/student/check_st?st_name=" + str1 + "&st_birth=" + str2 + "&st_class=" + str3;
     response.sendRedirect(urlstr);
Thanks in advanced.
Ilias

You should use the RequestDispatcher.forward(request,response) method.
For example, inside Servlet B do this:
public void doPost(ServletRequest request, ServletResponse response) {
    ... validate parameters ...
    RequestDispatcher dispatcher = request.getRequestDisplatcher("ServletC");
    dispatcher.forward(request,response);
}This prevents an extra request-response cycle to the client and between the .forward() and .include() methods of the RequestDispatcher, should be considered the preferred way of server-side redirection unless there is a specific need to go to the client first.
See the J2EE API:

Can I run 2 different domains with same name but on 2 different machines?

I am trying to setup 2 domains with same name (sharedcds1) on 2 different machines (Machine1 and Machine2).

Yes you can. Make sure that domains configured to use different multicast address. WLS uses multicast for communications between nodes in domain.
          although your configuration will work, you could have troubles if you going to execute inter-domain calls between domains/servers with the same names.

How can I send multiple string commands into a VISA write?

Hi Fellow LabVIEW users
I am very new to LabVIEW (2.5 months) so please forgive me if my lingo is not up to par.
How can I send multiple string commands to a VISA write. For example each string command looks like this
1) 3A00 0000 0000 FFFF FFFF FFFF 0000 0000 FF00 0000 0000 0000 0000 0033 (Scenario 1)
2) 3A01 0000 0000 FFFF FFFF FFFF 0000 0000 FF00 0000 0000 0000 0000 0034 (Scenario 2)
3) 3A01 0000 0000 33FF FFFF FFFF 0000 0000 FF00 0000 0000 0000 0000 0067 (Scenario 3).
and so on and so forth. And there are a number of scenarios.
Each String scenario will give a different string output which will be interpreted differently in the front panel.
Right now I have to manually change the string commands on the front panel to give me the desired output. How can I do this without manually changing the commands i.e. hard coding each scenario into the block diagram?
Thanks, any feedback will help.
