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.

Can we selectively flatten form fields in a PDF file?

I have a PDF with some form fields in it. I want to selectively flatten a few form fields in the PDF using a java API. I have checked the documentation and found a method transformPDF in the OutputServiceService. But this method flattens all the form fields in the PDF document.
Can we selectively flatten form fields in a PDF file? If yes how?
This was possible in Adobe Document Server V6.
Regards,
Ragha

You will need an event in the form that will indicate that you want the flattening done. Once you determine what that is it is simply a single statement for each field:
fieldname.access = "readOnly";
Now when the form is rendered, the user will not be able to get access to these fields.

Need Help ASAP my State tax form is in a PDF file and the attachment in my email says Please wait...
I tried downloading updates like it said to but it still will not display the document. How do I print the PDF file ASAP

Can you give us a LOT more info?
What email client? What version of Reader (I can only assume you even have Reader at this point)?
Please wait? I'm sure it says more than that, right?
Have you tried simply saving the PDF (it IS a PDF correct?) to your desktop and opening it from there?
Did you get this form from the IRS or did it come from somewhere else? If the IRS again, what version of Reader?

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?

Mysterious html form field?

Whenever I build & run an application, there's a form
field below the swf. It's either empty, or full of commas. This is
on Safari, Mac OS X.
Why is it there, and how can I not have it appear?
I know I can manually make a new html page and embed the swf
and have no problem, ut often I'd like to just choose "run".

Analyze the html wrapper that is generated. Probably some
field that is supposed to be invisible is not.
You can then modify the index.template.html file to fix it.

Friefox html form field issue

For some reason Firefox doesn't render html forms correctly. I have switched around my appearance recently and that might've caused it but since then I believe that I have tried switching everything back to how they were with no change. Other browsers show same pages just fine.
Following picture shows what is wrong. Firefox on the left and Rekonq on the right (Chrome and Konqueror behave the same).
I use up to date KDE.
Any help is appreciated.

Problem seems to be gtk-qt-engine related. Use my kde theme and manually setting qt4-theme won't work. But other gtk themes work just fine. Tried completely removing engine and re-installing, but didn't help.

HTML form posting with input type="file"

Hi,
I am trying to create a servlet to accept POST requests sent from a form which has an input field of type="file".
When I first tried I found that I was only recieving the filename of the file and not getting any contents.. I then found out that I needed enctype="multipart/form-data" in my html form tag.
Now my servlet isn't picking up any of the form data plus the reader returned by HttpServletRequest.getReader() just throws an IOException whenever I use it..
I have tried to google for how to get this working but I haven't found much. Any help would be appreciated.

Thanks cool..
I also found this after some late night googling..
http://www.jguru.com/faq/view.jsp?EID=1045507
I'm trying to not use one of these utility classes for now until I find out exactly how they get their data from the HttpServletRequest object..

How can I add form field value to the file name in save as dialog box

I do not want the form to be saved automatically, just want the form to auto populate the "file name" only.
A little background on the forms I want to use: My company has 70 retail outlets, I'll use one of our pdf forms called an "Incident Report" as an example. I would like for a store manager to be able to complete the form, then email the form to the main office (I already have javascript to add field values and form name to the email subject line), once the main office receives it, I want for them to be able to file the pdf electronically on our server. We have mutliple forms that we use so I do not want any of the forms to automatically save anywhere, (at this time anyway) I just want the office personnel to be able to click "save as" (or whatever they will need to click) and the form automatically add certain field values from the pdf they have received, of which will be different each time the form is sent to the office (Date, store #, employee name etc.) in addition to the name of the form in the "File name" of the "Save As" dialog box. The main office employees will decide into which server file the pdf should be saved.
I'm using Acrobat 8 professional, the stores and office personnel use Adobe reader.
One little note: We currently print and file a lot of paper on a daily bases, as soon as I can get this to work, we are going green.
Me and a lot of trees in this will really apprecitate any help you can give with this! :-)

You might want to take a look at the document "Developing Acrobat Applications Using JavaScript" (js_developer_guide.pdf) which is part of the Adobe Acrobat SDK, which can be downloaded here. Read the "Privileged versus non-privileged context" (p. 45ff.). You will find an example for "Executing privileged methods in a non-privileged context". Should be almost exactly what you are looking for.
Small Outline: For security reasons ("the user always has to know what's going on") you are not allowed to use the "Doc.saveAs"-method without the user permission (--> in a non-privileged context). In order to reach the goal of a privileged context you can use a trusted function. You do this by creating a JavaScript file (*.js) in either the Application-JavaScript-Folder (default location on Windows systems: "%ProgramFiles%\Adobe\Acrobat 10.0\Acrobat\Javascripts") or the User-JavaScript-Folder (default location on Windows systems: "%AppData%\Adobe\Acrobat\10.0\JavaScripts"). Add the following content to the new file:
myTrustedBrowseForDoc = app.trustedFunction( function ( oArgs ) {
     app.beginPriv();
          var myTrustedRetn = app.browseForDoc( oArgs );
     app.endPriv();
     return myTrustedRetn;
myTrustedSaveAs = app.trustedFunction( function ( doc, oArgs ) {
     app.beginPriv();
          var myTrustedRetn = doc.saveAs( oArgs );
     app.endPriv();
     return myTrustedRetn;
The developer guide actually wants you to add this content to the existing "config.js" file. I recommend creating a new file, since its easier to deploy in a network. Either way, every client/user who needs to be able to save documents this way, needs this JavaScript Code in his Application/User-JavaScript-Folder.
Within the Acrobat Document, which you want to obtain a certain file name, you can now use the trusted functions "myTrustedBrowseForDoc" and "myTrustedSaveAs" to store the file. To call the trusted functions and deliver the file name you can either you use a form field (button) or you add a new menu item. Add the following JavaScript Action to the button/menu item and change "Roller Coaster" to the name of the field which contains the value which you want to become the new file name:
var fileName = this.getField("Roller Coaster").valueAsString;
try {
     var oRetn = myTrustedBrowseForDoc({bSave: true, cFilenameInit: fileName + ".pdf"});
     try {
          myTrustedSaveAs(this, { cPath: oRetn.cPath, cFS:oRetn.cFS });
     catch(e) {
          console.println("Save not allowed, perhaps readonly.");
catch(e) {
console.println("User cancelled Save As dialog box");
Good Luck!

How to create new form fields in several columns (spreadsheet) and have them named consecutively?

Hopefully someone can help. I created a new form from an Excel spreadsheet, but the form field recognition didn't "take" well and very little of the spreadsheet translated into form fields. I need to create new fields (31) for each column (about 10) and I want the fields in each column to have a keyword from the parent column and the fields numbered consecutively. I'm really hoping I don't have to do this manually!
Next, is there a way to total the values in a column of fields (the same as the SUM function in Excel?) or does the form user have to dig out a calculator and add everything?
Can I create an email (submit) button and direct how (ie email) and by what method the form is sent?
Once the form is completed, is there a way for the user to lock it before sending it - ie a button they could press to make it no longer fillable? Or can I set the document to be a regular .pdf once it leaves the host machine?
I think that's it! Hopefully someone can help soon - this is a work project that could be potentially very time consuming if I have to create each form field manually. Thank you for any assistance!
Cheers,

Rats! Thank you for your link - I may take you up on that... however for the purposes of this form I'm more than halfway done, so I might as well keep plugging away. A workaround I found was to creat 32 of something I only need 31 of, then delete the parent. Somehow even playing with spacing on the "create multiple fields" option as the fields are being created only gets the vertical alignment close - no matter what I do I still end up manually aligning (vertically) 31 little boxes for each column so they fit visually. Grrrr.
Yes, this can be very tricky. If you don't get the exact right offset between each field, the difference will accumulate and after a while it will be completely off.
You just have to play around with it, until you get it right. Or almost right, and then adjust it manually.
Another thing I've noticed, is that when you select one field and right click for properties, you get an expanded version, as opposed to select/shift/enter for a bunch of cells only yields an abbreviated properties box - what's up with that? Is there a way to change this? For instance, I had set the properties for a column of 31 cells to be number, 1 decimal place. Halfway through my project, the lady I am doing the favor for tells me she would like 2 decimal places, requiring me to manually change each box for 62 cells! Apparently cell formatting is not an option in the abreviated properties dialogue! Is there a fix for that?
No, there isn't. Some propeties you have to set manually (or get right the first time, before copying and pasting...). There is a way to do it with a script, but it's a bit complex and requires using an undocumented method.
This next question is a bit more complicated, and may not be possible. The form I am creating is for payroll purposes, so at the moment it is generic (31 days) and the user fills in the month manually. Is it possible to get the form to recognize a month value (or create a pulldown menu with a selection of months to choose from) and limit the days accordingly? Or better yet, run a calendar function so that weekends and stat holidays are highlighted on the affected row? Kind of like what you can do with an Excel spreadsheet, which is what I designed the form in at the start (then printed to .pdf - the form field recognition did NOT work well on my spreadsheet! hence me doing every cell manually). Is this even possible, and if so, is it something I could learn to do?
Yeah, it's possible, but requires quite a bit of scripting knowledge. If you wish, contact me personally (by PM or email at try6767 at gmail dot com) and I could possibly create this for you.
If you want to do it yourself, you would have to learn a lot about both the Date object in JS and about the various date printing and scanning methods in Acrobat JS.

Can I script an email button to put one of the form fields in the subject line and to name the form?

This is a fillable form on a website. We want people to complete the form, then click on the email button to send it to us. Prefer to have the "name" field populate in the "subject line" of the email, and also rename the form that same field name. Is that possible?

In the sample I used the below syntax to send an email..
event.target.submitForm({cURL:"mailto:"+ strToAddress + "?cc=" + strCCAddress + "&subject=" + strSubject + "&body=" + strMessage,cSubmitAs:"PDF"});
The highlighted ones are local variables which will hold the value from the form fields.
If you want to get the Subject from Name field in the form, use some thing like this.
     var strSubject = name.rawValue;
     //and then pass the value to the code.
     event.target.submitForm({cURL:"mailto:"+ strToAddress + "?cc=" + strCCAddress + "&subject=" + strSubject + "&body=" + strMessage,cSubmitAs:"PDF"});
Hope this helps..

2 Questions on PDF Forms. Submit photo from file and templates.

Hey all,
I have successfully turned an outdated Word form into a PDF form. However, there are still two important thing I still want/need to accomplish:
1) Is it possible to create a space on form for the user to add a photo. By that I mean the forms we are dealing with are basically data collection of people, and photos of the people are important. Right now, there is no way for someone to add a photo of the person to the PDF form -- is it at all possible?
2) Can I turn a PDF form into a template much like a Word document? What I would like is for someone to open up the form and when they go to save it, it prompts them to create a name for the file so they don't overwrite the original. Possible?
Thanks in advance for any help or advice.

Yes, depending on the way your users will use the file and whether you have
access to their computers.
In any case, it will require some scripting work.

Jsp code (js code) to display(tree) the files and sub folders in a folder

Hi all
plz can any one send me the source in jsp or js to display in tree structure for files and sub folders in a folder.

There are dozens of Javascript tree widgets available on the Internet. Some are free. Some are good. Google will find them for you.
(The only relevance of JSP to your question is that yes, you can generate HTML that uses one of those Javascript tree widgets.)

Import statement in .java files and .jsp files

Guys I have few mysteries about this import statement.
Please correct me if I am wrong.
1)Suppose if I have a folder c:\SourceFolder it has one.java and two.java files.If I compile one.java then one.class files is created in c:\ClassFolder .Now two.java uses one of the method of one.java,and without using import statement I am able to compile two.java, and two.class file is created in c:\ClassFolder.I assume that the path of one.class was taken from the CLASSPATH environment variable,hence I there was no need for import statement .........am i right ?
BUT... in My.jsp,which is in C:\JspFolder, if I want to use one.class,then I have to specifically import the class I want to use.That is i have to say
<%@page import="one"%>
and since the classpath is C:\ClassFolder ,it finds one.class in the C:\ClassFolder.(Note that My.class is created in a folder different from c:\ClassFolder )
But I am wondering why was there no need for me to import one.class in two.java.
(Note I am using JDeveloper and Apache server)
Please help.
In this case the pSo I am wondering in JSP why it doesn't take the class I am looking for from the classpath .
Help.

You have to understand Java scoping rules. In the 1st scenario with the two Java files I am guessing neither one of them begins with a package statement. This means that they belong to the default package. When you compile the compiler uses the classpath to resolve method calls looking in the default package since there was no import statement specified in two.java. JSP is a little different. Now I just read this here in these forums a couple of days ago. Since the classfiles generated from the JSP files are not in the CLASSPATH they are loaded by a different classloader. This is why you have to import all references to all classes in the default package.

1)Suppose if I have a folder c:\SourceFolder it has one.java and two.java files.If I compile one.java then one.class files is created in c:\ClassFolder .Now two.java uses one of the method of one.java,and without using import statement in two.java I am able to compile two.java, and two.class file is created in c:\ClassFolder.I assume that the path of one.class was taken from the CLASSPATH environment variable,hence I there was no need for import statement .........am i right ?
BUT... in My.jsp,which is in C:\JspFolder, if I want to use one.class,then I have to specifically import one.class in My.jsp .That is i have to say
<%@page import="one"%>
in My.jsp.
and since the classpath is C:\ClassFolder ,it finds one.class in the C:\ClassFolder and MyJsp is compiled sucessfully.(Note that My.class is created in a folder different from c:\ClassFolder )
But I am wondering why was there no need for me to import one.class in two.java.
(Note I am using JDeveloper and Apache server)
Please help.

It has to do with packages. Most java classes are in a package, the name of which must conform to its place on the filesystem relative to the classpath. By that I mean that if you have com.mystuff.One.java, it must be in a folder com/mystuff where com is located somewhere in the classpath.
What you've done is a little different. I'm assuming a couple of things:
1. you have no package declaration at the top of one.java or two.java
2. you have the current directory "." in your classpath.
Java has the concept of the "default package", which covers classes without a declared package, and in your case is the current directory.
So when you're in c:\sourcefolder and run the compiler, then "."="c:\sourcefolder", and that directory is part of the default package. No import statements are necessary for classes that are in the same package. This is why two.java can call methods in one.java without an import statement.
When you run your jsp, the "current directory" part of your classpath is not c:\sourcefolder, but some other value (probably the directory you start your jsp engine from) You will have to import all non-java-library classes because the jsp itself becomes a java class, with a package that is determined by the jsp engine.
