Passing password to servlet

I need to authenticate a user. In an applet I created a name JTextField and password JPasswordField. I get the password with .getPassword().toString(). At the servlet I get a sequence of meaningless characters. How do I get the original password?
Thank you all.

Are you using Base64 encoding? If not I don't undestand your problem. You have an applet wich has a textfield. The user enters the password and then you send it to the servlet. But most probably you've got a problem while sending the password.
Two solutions for u:
1) Invoke the servlet through HTTP or HTTPS
2) Put the textfield directly in the web page (HTML or JSP) and then use FORM to send the data to your servlet.
If u want more details, please ask!
Hope it helps,

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!

}

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.

Correct, you need to encrypt then sign.

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.

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?

How to pass password from jsp to Applet

Hi ,
I can pass the user to applet like below. But password will be seen from view source.
How can pass password without showing in the view source.
<PARAM NAME="loginname" VALUE="<%=request.getParameter("loginname")%>">
<PARAM NAME="loginpassword" VALUE="<%=request.getParameter("loginpassword")%>">
Thanks in advance.
Rockesh

Or alternatively, determine why you need to pass the password on to the Applet.
For example, if the Applet needs to log into a resource, it is much more secure to ask the user for a password then, as opposed to getting the password from a form, passing it on to the Applet and then having the Applet blindly relay the password to the server, the database, whatever.
If the Applet doesn't need to do anything with the password, then I must question the wisdom of passing on the password in the first place.
If the Applet uses the password to do authentication, then the best solution is to generate hashes of the password and compare those hashes as needed. This would make it much more difficult for someone to either eavesdrop on it, or guess it through random trial and error. We can take it one step further. When the JSP code is executed - generate a one time unique password that's extremely long, at least 128 characters. Embed the password in the resulting HTML page as a hidden field and seed the Applet with the password. That would tie the Applet to a particular web page.
I really like SpinyNorman's JavaScript, but if that's indeed your purpose, you might as well do it in the Applet itself. In other words, it's kind of pointless to ask for a password in order to launch the Applet - once the user gets the Applet's URL by some means, he can just bypass the JavaScript authentication.

Passing password from shell script to Java

Hi there,
I have a shell script which has user id and password stored in variables. I call a java program from this shell script. I tried accessing this environment variable from java using system.getproperty and java is not getting the values. I have used export USERID PASSWORD
and java classname to call it.
I do not want to pass it as arguments because of security reasons. can anybody help me please.
Thanks a bunch.

Presumably you are using one of the newer java

Questions
1. What statements are you using to set, export and
run java?
2. What shell are you using?
3. How are you accessing the vars in java?
I do not want to pass it as arguments because of
security reasons. can anybody help me please.
That is nonsensical. Putting it in env vars exposes
it more than passing it as args.Thanks for replying jschell.
1. I am using newer version java 1.5
2. shell scripts gets it's variables from oracle reports through webservices.
3. to run java i use java javaclassname3. I used EXPORT variablename and in java called system.getproperty(variablename)But system.getproperty is getting a null.
And the decision about not passing it as args was made by our client. They think it's not safe to pass password.
are they wrong??
Please help me.

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);

No, it doesn't. I don't wan't to input password every time I restarted my laptop, but I don't want to keep my key unprotected for cases

jasonwryan wrote:This sounds like an XY Problem. What are you trying to achieve?
Possibly it is. I am trying to achieve:
After autologin my ssh key is in keychain (https://wiki.archlinux.org/index.php/SSH_Keys#Keychain), gnome-keyring and others seems
just to heavy and I can use it without writing my password. Writing my password for the key once is accetable, however need to manually
write ssh-add is not.
So if key will be added automatically on "ssh host" and I must input password first time I connect somewhere, I am fine with it..
I hope I made clear what I need.

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>wongyuenmei</p>
<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>

AIX 5.2 : how to pass password value while creating a user on AIX server

Hi ,
Test connection is successful with AIX server , I can successfully create a user on AIX server, with defualt password.
I am not passing the any password value still some default value is being populated for the user...
In AIX while creating the user , use get force to set the password...
But while configuring the schema for AIX adapter ...if password attribute is given then it will give the error
as invalid attribute...while creating a user if password value pass...
how to set the password for the user..what attribute need to set for the password .
thanks ..

The default password might be the IdM account password of the user you are trying to provision. You don;t need to keep password in the resource schema. Just set password.password and password.confirmPassword and select AIX resource for password reset. Check the workflow-form-views document for more information on password view.

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:

Hi,
Please be carefull about passing values such as Strings or number that contains ',' .
