Can a HTML form send data to two servlets?

I would like to know if an HTML Form can send data to two servlets, I guess I am askin is that can the parameters be passed to two ACTION attributes??

Hmmmm, well I'm not sure if that is possible, but you could do something of the sort on the server side by chaining them.... the technieque is called Servlet Chaining
Hope this helps

How can I get extract the data between two cursors on an XY graph

How can I get extract the data between two cursors on an XY graph

Well, you say xy graph, so this might be a more complicated problem.
For a waveform graph it's trivial. Simply get the two cursor indices (property: cursor index) and apply them to array subset of the data. Is that all you need?
Here's how the above code would look like. using cursor.index instead of cursor.x elimnates the need to include scaling information.
For an xy graph, there could be multiple segments (e.g. imagine a spiral that passes the desired x range multiple times from both sides). This would neeed significantly more code for a general solution.

How does a JSP page send data to a servlet?

I know, elementary school question, but I can't seem to do it no matter what I tried to do. Here is my code:
       URL url = new URL("http://" + ChatGlobals.SERVER_NAME + "/" +
                ChatGlobals.SERVLET_PATH + "/ppowell.ChatServlet?message=" +
                URLEncoder.encode("/a " + cookieArray.getValue())
out.println("<P>" + url.toString());
HttpURLConnection conn = (HttpURLConnection)url.openConnection();
conn.setDoInput(true);     // NOT REALLY INTERESTED IN INPUT BUT MUST BE TRUE
conn.setDoOutput(false);     // NO OUTPUT
conn.setUseCaches(false);
conn.setDefaultUseCaches(false);
conn.setRequestProperty("Content-type", "text/plain");
     * Do servlet connection to retrieve from ChatServlet URL instance
     * by instantiating an InputStreamReader object
     * @see ChatServlet
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String stuff = null;
stuff = in.readLine();
out.print(stuff);
in.close();
in = null;
conn = null;
Upon running this code my page just locks up.. URL: http://www.myjavaserver.com/~ppowell/chat.jsp
But if I call the servlet directly:
http://www.myjavaserver.com/servlet/ppowell.ChatServlet?message=/a+Phil
Everything works perfectly, no lockups, no errors, the log and txt files are created. So if my browser calls the servlet everything is ok, but my JSP script in the same directory as my servlet is the one that needs to call the servlet.
How then does a JSP send data to a servlet?
Please help, I've been searching in books and online resources for days now with absolutely no apparent luck to do it.
Thanx
Phil

It's correct that a JSP is compiled to a servlet. All HTTP servlets receive requests and send responses via HTTP, of course.
But this JSP is making a URL connection to a servlet and sending data.
Are you sure that the URL your JSP creates is identical to the one that works in your browser? Have you printed it out to stdout to verify that it's true? (Code inspection and "it looks right" doesn't count.)
Why are you doing it this way? It's common to have a JSP send to a servlet, but the usual way of doing it is to put an HTML form in the JSP, including an HTML <input type="submit">, and POSTing the form data to a servlet URL. Why aren't you doing that? - MOD

How can i fill selection box on html form with data on the clientside?

hi
i want to make a html form that reads option values from the client.
Because there are too many data, it's not reasonable for me to design a page which connects to server each time to fill the selection boxes.Instead i want to check if data resides at the clientside, if so fill selection boxes with that data, if not download it for the first time and store it on the client for later local retrieval.In addition i must be able to update that data residing on the client when i want.

Don't see where Java comes into this. Sounds like you'd be using JavaScript on the client.
A cookie would probably be the only way to save data on the client.

Render html form & send forms's input values as params via HTTP POST

Hello,
I'm using appache commons http client to send HTTP post queries to a given url and receive HTTP response then process it.
one of the requirements of my Application is the following: one of these HTTP Post requests is supposed to return an HTML form with different html types (text filed, text area etc..) that i will need to display in my swing application. one important requirement is that i can't know in advance what the html form field types will be.. it depends on a given parameters that my application send as part of HTTP Post method (using apache http client).
I Longly searched for a simple solution to this problem . There are many solutions but each one has it's limitations :
1-i can render the html form inside a JEditorPane .but how can I collect the user entered data inside JEditorPane ? i'm not sure this swing component offers the capability to detect its html contents and more it will be difficult to know what are the values entered by user inside html form rendered by JEditorPane.
2-are there any Java Embedded browsers that offer some API to enable me detect the html form fields ,capture the data entered by user inside the html form ?
3-the solution i currently opted for is : parse html & convert html form to swing dialog. currently this solution i use works well but the cost of implementing it is high : it involves difficult parsing logic. this makes me worried .I'm not sure if i'm now using the right & easiest solution.
I need some advice on What is the simplest and clean solution to render a html form & yet be able to collect user entered inputs & send the user input values as params via java HTTP POST request ?

In my opinion, your actual solution is what you need to do. You're trying to "merge" two different kinds of view. Actually, the "easiest" way may be: if you have your data to display, you decide to show it on html or swing.Yes i believe that my current solution may be the unique one for my special requirements. when doing research about this problem i found a multitude of java libraries to convert xml to swing (ex: www.swixml.org) .However i was surprised there are no java libraries to convert HTML forms to swing dialogs -as far as i know-. this is a bit strange. The Limitation is that the developers of the server API are not Java guys and are reluctant to use an xml format that i can easily convert to swing . probably they have their own reasons as they might be using the HTML Response for some other server side work. So I was obliged to deal with an HTML stream that i need to display in my client application and process its data. in my opinion the only way to do this is by developing a HTML form to swing converter package. that's what i did now. i was only worried if i'm complicating things and if there are some easier solutions to this issue.

Can I transfer Time Machine data from two separate hard drives into one new one?

I'm using a MacBook Pro as my primary computer. My 500 gig Time Capsule filled up a year or so ago, so I stopped using it with Time Machine for awhile so I could keep the data from those old back-ups. There were a number of things I deleted from my computer's very limited hard drive after they were backed up to the Time Capsule. I got a 1T external USB drive last year to use as my "filing Cabinet" to store files I didn't necessarily need all the time or that were filling up my small laptop hard drive--including my iTunes library--all organized in a way that made it relatively easy for me to find what I needed, even if I didn't remember exactly when I'd filed it or what I'd called it. I got another 1 terabyte external (portable) drive last July and dedicated it to TimeMachine backups and labeled it "TimeMachine".
Over the last couple of weeks, my friend has been helping me upgrade to Yosemite and clean up my laptop hard drive. Last week he cloned my laptop hard drive to a new 1T hard drive and I exchanged it for my old drive in my computer today. All good.
Here's the issue. We replaced my Time Capsule hard drive with a 1 terabyte drive with the idea of transferring the data from the old Time Capsule (500G) drive and the newer USB 1T "TimeMachine" compact drive to the new 1T Time Capsule drive and beginning using the latter for my Time Machine backups going forward. Originally he thought we could copy everything from each of my external drives (the old 500gig drive from my Time Capsule, the USB "TimeMachine" drive I've been using since July, and the "file cabinet" files) to my computer in their own folders and then start regular TimeMachine backups to the new Time Capsule drive, thus preserving all my old data and making regular backups going forward. The "file cabinet" data was no problem at all, but when I tried to copy my USB "TimeMachine" data to my computer, I was unable to. My friend found instructions for transferring old TimeMachine data to a new TimeCapsule, but I don't know if I can transfer the data from two separate disks to the new TimeCapsule drive. I'm afraid that one set of data will supersede the other and either my newer backups or my old ones will be lost if I try to transfer both.
Are my fears justified or is there a way to insure that no such problem will occur? Of course, my data will still be on those two older drives, but that won't do me a lot of good if I can't access it when I need to. Also, the 1T drive now belongs to my friend; he used a brand new drive he'd bought for himself for my new internal hard drive and plans to take my 1T "TimeCapsule" drive in exchange, once the data has been transferred, so he will, of course, erase that drive.

Should we be able to bring up the old (500G) Time Capsule Drive to rename it using a SATA to FireWire harness and then copy the whole thing to the new Time Capsule drive?
You can copy a whole sparsebundle from one drive to another. That is not a problem. Whether you can access the sparsebundle is something you should test before you even start though.
If it's on the Desktop and I don't tell Time Machine to exclude it from backups, will it just automatically back it up?
All drives you plug into the Mac are excluded by default.. you must include them. So no problems there.. but I hope I am understanding the question.
Will both volumes or directories (which is the right term?) show up when I open Time Machine?
No, Time Machine will only open what it is told to open... or its backup default location.
You can force Time Machine to open alternative/old/no longer used backups by (now I have a problem as things have changed somewhat in Yosemite and I consider it alpha release software at this point in time). The old method was to right click on the TM icon and select a different TM backup. easy. Yosemite seems to have made easy stuff harder.
Here it is on my current computer.. clearly not Yosemite.. Right click on the TM icon in the dock.. select Browse Other Time Machine Disks.. And supply the info of where that is located. Easy. If you cannot figure it out one of the other posters here (with more patience than me for Yosemite) will help you.
Or will we have to partition the new drive somehow--is that even possible?
I am getting more lost as I go down the list.. but the TC disk cannot be partitioned.
If you have included all those USB drives in the new backup on a Time a Time Capsule.. you have made life rather hard because now your files are stored another layer deeper than they were.
So to open a file from a disk you need to open the sparsebundle.. then dig down to the drive in question and then dig down to the backup.. and all of this means Time Machine has to work perfectly which is Yosemite is a very big ask.
I thought you wanted to just backup your old drives to central location.. which means copying the files to a separate folder on the Time Capsule.
One correction I need to make to my post, which will make my strategy make a bit more sense: my new Time Capsule drive is 4T
It makes it much harder.. and I have to pose a real question of long term .. if you have put a 4TB drive in a Gen1 TC.. did you also replace its power supply because I can assure you the drive might be ok but the TC itself will not last forever.. and what happens when it dies. The Gen1 power supply is already well beyond its normal life span and the vast majority are dead. When the backup device is unreliable and the backups on it are made that much harder to get access to.. is this a great plan??
If you are going to consolidate all your old files on one disk.. a task I find understandable. I have done much the same albeit the usefulness of files made on emac running OS9 may be questioned. A disk lying in the bottom of a draw is a more appropriate place for them.
You want those files as easily accessible as possible (at the point of recovery) and not buried inside a sparsebundle.. particularly not a sparsebundle from the old TC disk buried inside a new sparsebundle.. keep files as accessible as possible as you can run searches.. and that is best done on a USB 3 (or faster ie thunderbolt) drive plugged into a new(ish) computer.. not network. And since the files are not being accessed on a daily/weekly or even monthly or yearly basis.. keeping them in actively running TC network storage.. I would say is a waste of space. That is only my opinion of course.. you might consider it highly important that files you will never look at are available any time of day or night when the urge comes to track down that elusive pimpernel email you sent 10 years ago... but I find it hard to justify. What the case.. the problem with TM and things like Mail is you cannot search it.. you must restore the whole library/files/program even before you can access it.. that makes file recovery out of a sparsebundle double step process.
So.. summary.
If you want to store files on the 4TB drive in the TC.. that is not a great strategy but it can work.. simply create a folder named.. OldFilesEMac for instance.. and do a simple copy and paste of all the file to that location. Do not use TM.. Since you have already used TM.. and from what I am reading you have already done the backup with the external drives included.. then you are going to end up needing to erase the TC and start over.. which you may not be prepared to do.. which is fair enough. (I am coming across as overbearing school master.. apologies).
TM is to backup your main OS and current files.. not files from 10-20years ago.
Please do read the issues involved in Pondini..
See his FAQ. I recommend you read through Q14-17 so you understand what is involved in recovery.
http://pondini.org/TM/FAQ.html
I also recommend you read the first couple of articles here. http://pondini.org/TM/Home.html
Particularly so you understand the complexity of Time Machine.
And the articles here. http://pondini.org/TM/Time_Capsule.html
Particularly Q3 on mixing data and backups on a TC.
I wish I could spend an hour or two face to face and work it out.. the whole strategy to do this.. !!

Sending data to a Servlet. EOFException and StreamCorruptedException.

Hi!
I have a small servlet that receives some text from a client, and returns a response. The problem is that when i try to receive the data in the servlet, I get and EOFException. And when the client tries to read the response, a StreamCorruptedException is thrown. Can anybody please point me in the right direction here?
The code for servlet is as follows:
     protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
          DataInputStream in = new DataInputStream((InputStream) request.getInputStream());
          String message;
          String text = null;
          try {
               text = in.readUTF();//EOFException thrown here!
               message = "100 ok";
          } catch (Throwable t) {
               message = "200 " + t.toString();
          response.setContentType("text/html;charset=UTF-8");
          response.setContentLength(message.length());
          in.close();
          PrintWriter out = response.getWriter();
          out.println(message);
          out.flush();
          out.close();
          System.out.println(". Received text: " + text == null ? "none" : text);
     }And the code for the client:
     @Test
     public void test2() throws IOException, ClassNotFoundException {
          String input = "This text is to be sent";
          URL serverURL = new URL("http://localhost:8080/myURL");
          URLConnection con = serverURL.openConnection();
          con.setDoInput(true);
          con.setDoOutput(true);
          con.setUseCaches(false);
          con.setRequestProperty("Content-Type", "application/x-java-serialized-object");
          OutputStream outstream = con.getOutputStream();
          ObjectOutputStream oos = new ObjectOutputStream(outstream);
          oos.writeObject(input);
          oos.flush();
          oos.close();
          InputStream instr = con.getInputStream();
          ObjectInputStream inputFromServlet = new ObjectInputStream(instr);//StreamCorruptedException thrown here ("invalid stream header")
          String result = (String) inputFromServlet.readObject();
          inputFromServlet.close();
          instr.close();
          System.out.println(result);
     }The EOFException is thrown at the line text = in.readUTF(); in the servlet, and the StreamCorruptedException is thrown at ObjectInputStream inputFromServlet = new ObjectInputStream(instr); in the client. What is wrong here?

Your server reads a UTF-encoded String with readUTF().
So your client should write a UTF-encoded String with writeUTF().
Your server writes lines with PrintWriter.println().
So your client should read lines with BufferedReader.readLine().

Make html form send xml

hi,
i am facing a bsp-development in XI-context. As the XI expects xml-input via http-channel I need to set up forms which can send the query-string as xml.
eg
thisPageToXI.htm?name=john&job=nap&age=34&...
I was looking in my WAS and found a couple of function modules, which can convert stuff to xml - most of them derived from crm apparently. But they're all a bit unhandy.
How would you deal with that task?
thanx in advance,
matthias

Matthias,
Always in these discussions confusion is abound because questions is not formulated perfectly.
First you write: "I need to set up forms which can send the query-string as xml". In this picture I have a browser, and when the request leaves the browser to go somewhere, you expect the payload to be in XML format.
But then you write this example: "?name=john&job=nap&...". Hmmm.. here things are just simple name/value pairs. No XML.
And then suddenly you write "I was looking in my WAS ...can convert stuff to xml". So now we are suddenly on the server, without XML in hand, but wanted it.
All confusion. So let we first draw a picture:
(1) browser --XML--> XI
(2) browser --name/values--> WebAS(BSP) --XML--> XI
In scenario 1, the browser prepares the XML document directly, and sends it directly to the XI server. I know of no technique to achieve this form HTML. Your posted examples using the ActiveX XML object in the browser is probably the only way to go. Will just require some JavaScript to find all the correct formfields, and feed all of this into XML object.
In scenario two you just submit a normal request to the server. You use something such as get_form_fields and concatenate to build the XML string. Then you make an outgoing HTTP connection to XI using the HTTP Client. Somewhere we have examples of how this can be done.
But first, for me at least, is the question of what you wish to achieve.

PDF form sending data back as FDF

Hi there,
I created a pdf from a Indesign doc and opened it in acrobat 9 to use form wizard, I successfully managed to save and send the pdf from my mac to my partners pc. He was able to fill in the form but when clicking the submit by email button it was only sending me back the FDF file. I checked my settings on the submit button but had checked the box for 'PDF the whole document'. I had notes from an earlier version of acrobat and it stated that after I have created the form and saved the mailto button etc, under 'advanced' I should click on 'Enable usage rights in Adobe Reader'. Yet I could not find this so I tried 'Extend features in Adobe Reader' but this stills sends me back the FDF file which I cannot access the data from.
Ideally I would like the pdf to come back rather than the FDF is there any way this can happen?
Kirsty

Sorry, but I am a little confused.
Let me give you a scenario.
The user clicks the button on the JSP it sends the primary key value or user id to the servlet.
The servlet calls my session entity beans and returns data base on that call.
At that point the servlet has the data. Even if I set it in the session object in the servlet, I will have to populate the jsp how?
Do I set the values on the jsp from the servlet or within the jsp itself? Use setparameter, setattribute?
The button click starts it all off, but when the servlet is done processing, will I need to detect some other event in the jsp if I want to to populate the fields from within the jsp?
In other words, if I put code in the jsp to populate the text fields after the servlet is finished executing, what triggers the code ((YourObject) request.getSession().getAttribute("your key")) to process inside jsp?
I am making sense.

Sending data between two companies

hi
my client has two companies
but the work is same by the both companies,he use one for one area and another one for different area.now when i create 2 databases 2 companies. but the problem is that the inventory should be managed between the 2 companies like if he don't have a product in 1 company then he can bring from other company and send it to them.but there should not be any financial transactions in this process
any one has any idea how to link up 2 companies.

Hi Praveen,
You can use integration products like iBolt or maybe SAPs B1i to synchronise item master data. You could also write your own addon to do this. My gut feeling is that iBolt would be an expensive solution if you only want to match the item records (as you'd only be using a tiny bit of its functionality). The B1i software comes with SBO 2005A SP1 and 2007A (I'm not sure about other versions or clusters). You could try asking about using this on the following forum:
SAP Business One Integration Technology
Writing your own addon wouldn't be that difficult but obviously requires knowledge of programming using the SDK.
Kind Regards,
Owen

How can I have iPhone send data back to my Mac

I have an idea for a project. To make my idea possible, I plan to use the NSSpeechRecognizer, or speech recognition on my iPod (really any form of speech recognition). Then, I want my iPod to send what it heard back to my mac as a string. I would like to avoid using iCloud, but if I have to use it, I am okay with that. So for example, I could say "Hello" to my iPod, and my Mac would somehow get the string "Hello" from my iPod as input to a program. Is this possible?

Thanks for your ideas, Ralph. I never did find my old script.
I solved it with a work around. I can't figure out the SMS, but I decided I could just send myself an email notification. Then, I can have my phone tell me that I have a new email with an alert. I hope this helps someone else.

I would appreciate your help with this real-world scenario.

Hello
I am using Web Client with the DownLoadFile() option to download files from a site. If too many requests come in too fast it will banned that address for 24 hours. (A DDOS security measure) I need to have the program wait until the file
is downloaded before making the next request but be running in the background so not to freeze the application. A progress form will allow the user to know the status of the downloads.
I see something about asynchronous downloads but do not seem to understand how I would make use of it or if it is the method I want to use.
If someone could point to or give a good example of what I need to do, it would be most welcome.
David Edwards
David,
There are two ways which come to mind here, both using the WebClient:
The first is that in a BackgroundWorker, you use the synchronous download method. The synchronous method is a blocking call so obviously it can only get one at a time, and when that one is completed, the loop then starts the next.
The second way - also in a BackgroundWorker - is to use the asynchronous method. The reason for this is because only the asynch method provides events to monitor progress and know when the file has completed. This gets a bit more involved because you're
still processing them in a loop, but it's definitely something that can be done - I've done it several times.
You haven't really given many details, so beyond this general conceptual description there's not a lot more that can I can explain, but your goal definitely can be achieved using a WebClient.
I hope this helps. :)
Still lost in code, just at a little higher level.

Send data between two applications

Hi!!
It's the second time i write in this forum and i hope u undersand my english because i'm argentinian.
I'm developing an application that processes data received from sockets and the result should be sent to another application but i can't use sockets for that purpose. So i thought in something like a printer queue but i don't know how to implement it and i hope u can understand me.
Please help me!!!!!!!!!!!!
Bye!!

Hi again!!
I'm gonna explain what i'm doing and what i need:
i'm developing some applications that communicate via sockets, but i'm not allowed (the owner of the company didn't let me) to use threads. The problem is that one program should be listening to two different clients so i divided it into two differents applications that communicate each other NOT using sockets. So i thought that i could develop something like the priniting queue and both applications every 2 seconds for example will pop messages pushed into de queue. Well, i think i explained a little more what i need and i hope u can help me.
Bye!!!!!!!!!!!!!!
