want to generate a html form page with dynamic data and submit this form to a url

Hi friends,

I am having an applet, and it has a button(say submit) to extract some dynamic data from backend system and generate a html form page with this data and then open the this newly created html form and submit it to the url mentioned in the form.

Can anyone suggest me how I can do this.

My html page file content is as below shown:

<HTML>
<HEAD>
</HEAD>
<BODY>
<FORM id='JCLCreateLetter' name='JCLCreateLetter' action='http://20.17.17.146:9080/CCM/NBPIPostInputHandler' method='post'>
<Input Type='hidden' id='BPI' name='BPI' value='CV_PEK_online_no_comp'>
<Input Type='hidden' id='groupName' NAME='GROUPNAME' VALUE='CV_PEK_Online'>
<Input Type='hidden' id='userName' name='userName' value='CV_PEK'>
<Input Type='hidden' id='role' name='role' value='CV_PEK_online_pgm'>
<Input Type='hidden' id='xmlRecords' name='xmlRecords' value='<Record01><CompanyId>PEK</CompanyId><CnvLetterId> </CnvLetterId><AlphaProcessDte>JUNE 24, 2009</AlphaProcessDte></Record01>'</FORM>

the complete html code shown above is stored in a String object.
I do not have any idea of how I can write this String to a file on the fly without storing it any where and then open this html file(since I do not to store the file on the user's m/c and its not possible to write it on server without using any server side code.)

Hi Vishal,
You take a Stringbuffer and push all the string.Finally write the content of StringBuffer to the file object .Gothru I/O tutorial.

Ex:

1.Append the String to StringBuffer object.
2.Finally convert the StringBuffer to String and write to a file.

Ex:
StringBuffer sb = new StringBuffer();
sb.append(".....Ur html contents");

FileWriter fstream = new FileWriter(new File("test.htm"));
BufferedWriter out = new BufferedWriter(fstream);
out.write(sb.toString().trim());

Hi,

I am having an applet application. From applet you can not write and save a file on a server.

can you suggest something by which I can write the file to server or launch the page by passing the String variable to javascript or something.

Is there any other way to do ?

I tried signing my applet but somehow its not working.
During signing do we have any step to grant read write permission to certain set of files.

A servlet to serve the content

Hi Vishal
Just some thoughts.
Will it not be easier to set up a servlet to serve the HTML you have in a string.
Set up a servlet and give it a URL.
Then use the Applet api to open the URL.
If however this is not possible; then the applet needs to be signed and a policy file generated. Here's a quick tutorial from Sun

java.sun.com/docs/books/tutorial/security/tour1/index.html

Thanks

Javascript Applet communication

Another way to achieve the same thing is through javascript.
You need to expose your string using a public getter method
say

Quote:

public String getHTMLString(){
return HTMLString //return your HTML String
}

Now when you are embedding your applet you can get the HTML String using scripting see :

java.sun.com/j2se/1.4.2/docs/guide/plugin/developer_guide/js_java.html

or search for "javascript to java communication" or "scripting applets"
After you get a handle to string you can use document.write function to embed that HTMLString in the page and submit the form after that.

Hope this view point helps
