Setting fields on html page from servlet

I have a HTML Page1 on ServerA that calls a servlet on ServerB. I want the servlet to load Page2 on ServerA and set fields on Page2.
I know I can do so by using Redirect and passing parameters in the URL that can be loaded in the onLoad event of Page2 but I was wondering if there is some way I can cause the servlet to set the fields directly.
I have looked a getRequestDispatcher("url").forward but it seems to me that the page being called would have to be on ServerB (the servlet's server). Am I correct? If not how do I get this to work? I have tried getRequestDispatcher("Page2").forward() and getRequestDispatcher("/Page2").forward() but neither seem to work. I assume because the pages are expected to be found on the servlet's server?

thank you!
I do put a bounch of System.out.println statements in it. one is just before the out.println("<html>") statement. another is before response.sendRedirect(). My program can print out each of the System.out.println(). but stop after that.I really do not know why!

How to call a html page from servlet

i want to link a servlet to a html page, if i use requestdispatcher, it says XXX.html is not available, can anybody help

Can you be more specific about what you're trying to do? Can't read your mind =). But if you mean you want to just have an static HTML page such as a header read by the servlet you can you the requestdispatcher include().
Create a servlet to generate a page, and then map it as /getPage in the web.xml file. Then you can use:
// header
RequestDispatcher rd = ...getRequestDispatcher("/getPage");
rs.include(req, res);
// the rest of the servlet output
// and you can do another one for the footer down here
rd = ...getRequestDispatcher("/getPageFooter");
rs.include(req, res);
and it'll output the HTML in the servlet.
Hope this helps

Calling HTML file from servlet and vice versa...

i have got few questions..
1- if a site is made in HTML then what should be used to put user login functionality in it, servlets or jsp or other option(specify)?
2- im trying to do with servlets, so when im calling doPost method from HTML page and sending data, everything working fine but because of this the page refreshes and the HTML coding get lost, so how can i stop that from happening if possible, like showing the same page with messege = "Logged in".
3- how can i call an HTML page from servlet?
4- how can i send data from servlet to HTML page?

that i m aware of, but when a servlet is called then the page will refresh n it will display the things that you have mentioned in the servlet file n not the things that u have mentioned in HTML file, n the page will be blank if u have not mentioned any HTML coding in servlet file.
so i need to knw how to call back that prev HTML file so that the things i want to display can be displayed, i knw the same can be done by adding the HTML code in servlet file but i would like to know if there is any way to call back the HTML file.

HTML should looks like:

          | Row 1 value 1|Row 1 value 1|Row 1 value 1|Row 1 value 1|

          | Row 3 value 1|Row 3 value 1|Row 3 value 1|Row 3 value 1|
          | Row 4 value 1|Row 4 value 1|Row 4 value 1|Row 4 value 1|
Page row 3
     |Caption 1 |Caption 2 |
     | Row 1 value 1|Row 1 value 1|
     | Row 2 value 1|Row 2 value 1|
There can be many levels but always table item is leaf,
Thanks in advance,

Hi
You are probably better posting in the flash forum, as without seeing the code, (and if it is not standard flash html publish) they can probably better advise on a solution.

Referencing static html pages from jsps...

          Hi,
          This is probably a very simple thing to solve, but I'm having problems with referencing
          html pages from jsps under Weblogic.
          I get Error 404 - not found, whenever I try something like this in a JSP...
          <frame name="title" src="title.html" scrolling=no>
          The title.html file has definitely been copied into my ear file, and yet it isn't
          found. I can solve the problem by turning title.html into a jsp and registering
          it in web.xml. But this seems like serious overkill with static content!!
          Am I missing something really simple here?


          I've worked it out - directory mistake...
          Thanks,
          Chris

How to Create HTML page from portal

Hi
I have a requirement to create html pages from portal.
There will be an author who can choose document type as HTML
and then he will write html codes on saving it should be saved as HTML doc in UCM.
and publisher should be able to display it on portal(may be using content presenter).
please help me in this. I know there is rich text editor task flow which can save a doc as doc file.
and in spaces we have option of creating HTLM file but i don't know how to do it for my portal.
Thanks

A better way would be to create the page using approach in this blog:
https://blogs.oracle.com/ATEAM_WEBCENTER/entry/content_presenter_cmis_complete
That way the page can be edited inline and the html author need not upload html to ucm everytime.

How to cache a content item like a Static HTML Page from UCM to Coherence/C

Hi All,
How to cache a content item like a Static HTML Page from UCM to Coherence/Coherence Web?
Thanks

Hi,
Could you explain your use case in more detail?
It does not look like proper use of coherence to cache static content - it more suited for dynamic content like user session etc.

How to extract HTML page from the internet

i am new to java, i wish to know how to extract Html page from the internet and also how to identify the differences between the images and text information?

You can create a java.net.URL that points to the file you want to "extract" and read the HTML code (or what ever that file contains) from there using the inputstream given by URL.openStream().
The difference between images and text... well, images are embedded in html using the img-tag. example: <IMG src="http://forum.java.sun.com/images/reply.gif" alt="Reply">. Attributes width, height, alt are sometimes left out and there may or may not be quotes around the values and everything is case insensitive... you'll be having hard time trying to parse the input so I'd suggest using existing parsers.
What are you trying to do anyway? You can load a URL directly to a JTextEditorPane with the setPage(URL page) method...

Open HTML page from the stage

How can I open a HTML page by pressing a button on the stage?
I've created a rollover button and I'm trying to make it open
an existing html page from the local disk (not an internet URL).
But I can't make it open with Lingo or behaviour.
Please help.
Thanks a lot.
Gideon.

goToNetPage "
http://somewhere.html" is the
typical form for a page on
the web, director must use the address format the system's
browser uses
for local files, this is somewhat platform dependant, a
practical
aproach is to open the file in question from within your
browser then
copy and paste the displayed address into your lingo code.
Some report the goToNetPage counterpart provided by the
buddyAPI xtra
works more reliably, the xtra can be used for free if limited
to a
couple of functions.
An alternate approach buddyAPI can use is to have the browser
directly
access the html file as if it were double clicked in the file
manager
using the same form commonly used to open PDF files with
acrobat.
(sorry I don't have example code handy)
