Pass data to JSP from HTML?

I can pass the data in a HTML form without problem if the form is in the same jsp file. I have no problem to pass data from one jsp file to another one. But when the jsp file has to take the data passed from calling HTML file and has to receive the data from the same jsp file, then the data from other HTML file will be null the first time runing the code, then second time will be passed right. If I shut down computer run the code again, same problem until the second time. Please tell me why if any of you know!

yes. The first part is HTML file which use the form to pass v_progname, the second part is a jsp file, it suppose to get the data in v_prgname, but the first time to run this code always get null, then the second time get the right data?

Passing values to jsp from html..

Hi all,
I have a jsp containing a selection list and need to pass the value to the java segment of the jsp. When reserching this, I've found some info where an html page was created, an initial jsp was saving the info (or bean was used) and then a third jsp displayed the data (using buttons). This is too many steps and I'm needing a way for the same jsp to display containing the selected option (simulating a refresh with the post when the drop down list is used). Is redirecting while setting and getting attributes all at once feasible/possible or is there a better direction or work around for this?
Thanks in advance,
Geoff-

I would think submitting the page to itself, and setting hidden fields to signal that it is a resubmission, may be the way to go. If the new information being displayed is minimal, JavaScript may also work, by setting up an empty <div> or <span> and setting the innerHTML or innerText properties. The advantage of the JavaScript solution is it would be quicker, having the client do all the processing, but it also browser dependant.

How to passing value into Captivate from html?

How to passing value into Captivate from html?
Or
How to communicate between objects in one slides?

Hi czhao0378 and welcome to the forums!
Captivate does not natively allow you to communicate your own
data, either internally or externally. The only way to make this
happen is to create your own functionality, either via custom-built
Flash objects or JavaScript code executed in the browser or a
combination of both.
The only example I've seen of any "data passing" inside
Captivate is a custom text input/output solution that was posted on
the Captivate Developer Exchange:
http://www.adobe.com/cfusion/exchange/index.cfm?event=extensionDetail&loc=en_us&extid=1253 021
This solution consists of an input box that takes information
from the user on one slide and a second box that displays that
information on another slide. The functionality was built in Flash
and is embedded in Captivate as a Flash "animation". Unfortunately,
since this is a custom functionality, the information is not
included in the user completion results Captivate can pass to a
Learning Management System.
Since the solution mentioned above relies on a Flash
Actionscript variable to hold the information that is displayed,
you can also pass the information from HTML to Captivate using the
"SetVariable" command in JavaScript. This would at least allow you
to display your own HTML-based data inside Captivate.
Beyond that, I'm not aware of any other way to gather and
pass data in Captivate.

Passing vectors into JSP from Servlet and passing data back to Servlet

I have been building an MVC application.
It has a controller which instantiates classes and evokes methods to
populate vectors. These vectors are then passed into a JSP. This part of the application works fine.
What I am having trouble with is a new JSP I have designed; this will
display the data that is actioned by the FORM action. This is actioned
based on the Search criteria entered by the user. Based on this a further vector is populated and brought back to the JSP as a vector
and this is rendered via the TABLE tag. Again this works fine.
Against each of the rows displayed, I have a print checkbox which can be checked by the user. On checking the records they want to print, they should then hint a Print button which should go back to the Servlet and print the data. THIS IS WHERE I HAVE THE PROBLEM. On going
back to the servlet the checkbox values are not displayed, rather
the values that initially populate the JSP. How do I get these new values back into the vector and hence accessible from the Servlet.
Any help with be very much appreciated.
Chris

Thanks for this.
Just to clarify I am not using Struts.
What I am having difficulties with is the fact that:
I can't get the checked values back to the Servlet - they keep the values they have in the bean - so as part of instantiating the bean class I set the value of the item to 'off'. The user will then check
the checkbox which should presumbably set the value to 'on'. This isn't happening because the setter method of the bean is not evoked again
because I don't come into this JSP again - the Servlet has finished here
and now needs to print the records. It can't do this because as
far as it is concerned nothing has changed since it last passed through
the vector to the JSP.
Even when I do the following:
Enumeration paramNames = request.getParameterNames();
String param = null;
while (paramNames.hasMoreElements())
param=(String)paramNames.nextElement();
System.out.println("parameter " + param + " is " +
request.getParameter(param));
what comes back is the valus of 'off' as opposed to 'on'.
The other thing is that 'request.getParameterNames()' only works
with the first record in the vector, i.e. it doesn't fetch any other
records that are rendered in the <TABLE> tag.
In desperation is there anybody out there who can help me.
Thanks
Chris
I am going to assume you are using a MVC framework
like Struts or very similar (I am assuming that from
the language you are using).
When the servlet passes the vector back to the JSP
page and you render the HTML that is passed back the
client your Vector is gone. The Vector is not
available at the HTML level that is being viewed at
the browser.
When the user selects the checkboxes and submits the
page (by clicking the print button) the controller
servlet (called ActionServlet in Struts, yours maybe
called something else) forwards the request to the
appropriate JavaBean and Servlet to process the
request. Either the JavaBean has to recreate the
Vector (not recommended) or the processing Servlet can
(better). You can do this by recreating the Vector
from scratch for the HttpRequest parameters or, at the
time of the initial request, saving Vector to a
session and then updating with the data you get back
from the client (again from the HttpRequest
parameters).
Either way you have to work with
HttpRequest.getParameter().

Passing data row-wise from one VO to another.

Hi,
I am a ADF newbie so I have a slight issue which I am not able to resolve.
I need to pass data from table t1 to table t2 which I am able to establish by creating viewlink between the two. But each time I press the 'CreateInsert' button for the VO made for t2,I need a different value to be passed. Basically, I need to pass values rowwise from t1 each time the user clicks the 'CreateInsert' button for t2 VO.
Eg. If there is an itemCategory table which contains the attributes for an item such as Expiry Date,Food Code,Type of food then for the itemFood, each time I click the 'CreateInsert' button, a new row should be created where attributeId has to be passed one by one i.e. on first click Expiry date should be passed, 2nd click food code should be passed so that based on these attributes,corresponding attribute values for itemFood can be entered in the itemFood table.
How can I achieve this in ADF? Is there an alternative way where instead of clicking the 'CreateInsert' button, attributeids cn be passed from itemCategory to itemFood?
Any help in this case is highly appreciated.
Thanks & Regards,
Chaya

Is it possible to pass multiple values for same attribute from one table to another using viewlink?
eg. If there are 2 tables- FoodAttributes which contains the type of food and the attributes associated with it.
say,Type -Vegetable, Non-veg, Fruits then for vegetables,attributes can be weight,leafy,etc.
Another table is FoodTable where we have food specific attribute which contains name of food ,attributes associated with it and the values for those attributes, like cabbage is name, attributes associated with it are leafy,weight and in values we specify leafy as yes and its weight in kg. So I need to pass the attribute names from 1st table to 2nd table. Please suggest a way to do this.

Passing data to and from Comm Sub Vi with 2 loops

Im sure this is simple, and I think Im stuck in vacation mode and cant wait the 4 more hours till I leave, but this is really bothering me. I have a pretty large Queued State Machine and within that machine I have some states which must communicate via the TCP/IP port. My servers are complete and made into Executables and work fine, however I want to leave my clients as sub vi's so that I can easily pass in and retreive data from them. They are designed with 2 while loops, one for sending the data and one for reading the data back. At the very least the read loop needs to remain in a loop to pick up unsolicited messages from my CAN server. However when I place these into my master QSM they hold up the process because of the loops executing. Now I have made a separate loop in my QSM for all my communication clients so the rest of the QSM runs but I cant pass data into these clients because they are stuck executing the loops internally and dont stop to pull in data.
I should note that if I run my QSM to spawn the servers, then run my client as a separate VI rather than a sub and type my commands there then they execute perfectly.
So if you can follow my crazy description what would be the best/cleanest way to circumvent this so I can get moving ahead. Thanks, Dave

Dave,
Would it work to use a queue to pass data from your main QSM loop to your communication loop? You could write the commands to the queue from your main QSM loop, and pick them up in the communication loop. They would then still run in parallel. Let me know if this works, or if you are looking for something else.

Repeatly passing data to and from external program

I'm looking for some help to get me started. I'm willing to bet
the info is here I'm just not sure what to look for and my searches
aren't reveiling anwsers.
Background: I'm trying to take control of a device that is comunicating
through the PCI bus. The device has a set of API dll's that I can
access through C++, but not directly in LabVIEW. So wish to creat
a wrapper program that will give LabVIEW indirect access to the
dlls.
Problem: I've breifly read up on CINs and Libaray call functions and
have found one underlying problem with both. I have not found a
way to pass data back and forth between the external code and LabVIEW
once the external code is running. I require an interactive
conection between the two.
Any sugestions of what to search for would be greatly appreatiated, or even how to resolve my problem.
Thank you.
Don't get even, get odd!

If the data buffers are owned by the driver and are updated asynchronously, you should expose that buffer to LabVIEW as a handle (simple int32 for the pointer to the buffer). This can then be passed to the wrapper code and checked (implements your polling). Remember that handling tasks in LV that should run in parallel is different from C++ however - you don't create threads, instead you should simply set up independent loops.
I'm not sure what else to suggest since I don't fully understand what the API does or what the HW is doing, so feel free to post more information if you want more suggestions

Data in .jsp or HTML form fields, to a JAVA File and DB

Hi,
I am new to the JAX-RS, I have a form where I fill in some details, There is a submit button towards the bottom of that form, when I click submit, it needs to do two actions:
1) Pass the data in different fields through different variables to into a JAVA file. I am not sure on how to call a JAVA file or program's method from either .HTML or .JSP
2) Extract the data from the fields and populate a DB through JDBC Connection
Your help is greatly appreciated!
Thanks,

If you're looking for some to write the code for you, you're in the wrong place. If you've tried to write it yourself, but are stuck on an error message, logic issue, or something similar, feel free to ask a question!
If you submit code, don't forget to use the code tags. If you submit an error message, be sure to copy the entire message and stack trace.

Pass date value back from called form

I have a form that allows the user to select a date from a calendar canvas. I can call this form from another from and now want to pass the selected date on the called form back to the calling form. I'm new to multi-form applications so I'm looking for some guidence here. I am thinking a parameter list would be better than a global variable since globals only support char values. I've never done this before so any advice or examples would be helpful.
Thanks in advance,
Jeff

Chander,
Thanks for your reply. I think this is the .olb I am using. I created my calendar form using it or a similar .olb. The form runs OK, just lacks the means to pass the "date picked" to the calling form. This is where my inexperience is making things difficult. Assuming we are talking about the same olb, how do I pass the date back?

Report with Form Passing date to form from report issue

Hi All ,
I got stuck up in the below issue .Can anyone point out the issue behind it and how to get rid of this.
I have created a report page with form page .The report page have 2 column identified as conjugate primary key.the col1 is varchar2 and col2 is date .
The report page have one link on col1 field which is passing the Item_value for both col1 and col2 to form page .
In the DB level the col2 data type is date (for e.g : 26/07/2007 07:08:56) .But the probem is when we are clicking on the link of col1 it is displaying error like Error like ORA-01403: no data found .
But if the data in DB is only in format of DD/MM/YYYY removing the timestmap the link is working fine and returing data for other fields in the form page .
Could anyone pls pointed out the problem and let us know the issue.
Thanks in advance.
Regards,
Deba

Hi Deba,
I suppose your problem is due to the : in the time.
You're passing these values with the url I suppose? Have a look how APEX generates/constructs the url, it uses : to separate things.
I'm not sure why you want a date in a Primary Key?
Thanks,
Dimitri
