Need help on webservices

Hello..!!
Kindly help me...
I want to build webservice with java/jsp as described below...
the client will just type the sql query in the text box provided on html (or jsp???) page. and the resulted string from the database will be displayed in the browser.
So, which technologies I should read? Like there are JAX-RPC, SAAJ, etc. and how can I invoke the sring from the database (say MySql) like '2 rows updated'....
please help.
Thanking you.
.Mohit

To narrow down to issue, can you very that the content is same as BI report? for that save the content with file extension as .html and open in browser.
Let me know updates?
Pls mark if helps

Need help in webservice to JDBC scenario

Hi All,
My scenario is a synchronous webservice to JDBC scenario. The SOAP request contains two fields one is ID & the other field is Date which is an optional field. I need to perform a SELECT statement on JDBC based on ID & Date. SOAP request will always contain ID field & Date may or maynot be there in the request. If Date present then search should be based on ID & Date , if Date not present search should be based on ID only. How to achieve this with the help of standard JDBC reciever structure or is there any other way to achieve this?
Thanks
Navin

You can create your target structure as shown below and check the existence of DATE field in the source(using standard function "Exists" ) and then only create the target DATE node.
<StatementName>
          <dbTableName action=u201DSELECTu201D>
              <table>realDbTableName</table>
              <access>

              </access>
              <key1>

Pls AnyBody Help
Thanks in advance

If you actually need a portal service though, this will not work. However, you could have the portal service return a Document object, which is basically the text of the HTML file you want to display. Then, when calling the portal service, you can simply output the text to the IPortalComponentResponse object
I hope this helps

Need help in returning error condition from web service

Hi,
I need one help regarding webservice. Currently my web service is returning "true" value when it works fine without any issues but it returns "false" when any any error is encountered. So my question is, can we return error instead of string "false". I dont know how to return exact error from webservice. If you any idea then please mail me.
Below is a small code snippet:
System.out.println("User "+ userFullName + usrKey + " end date has been updated to "+usrEndDate +" in IDM DB");
result = true;
catch (tcAPIException e) {
log.error("Error in finding the user" + e.getMessage());
result = false;
} catch (tcUserNotFoundException e) {
log.error("Error in getting user status" + e.getMessage());
result = false;
} catch (tcStaleDataUpdateException e) {
log.error("Error in updating end date of user" + e.getMessage());
result = false;
}catch (Exception e1) {
e1.printStackTrace();
result =false;
return result;
Here i want to return error instead of false. Can we do that?
Thanks,
Kalpana.

instead of storing false store below
use result=e1.getMessage();

Need help to host my coldfusion website

HI all ,
I need help from you guys where do i host my website developed in coldfusion. I hosted on Godaddy.com last month and they are going to discontinue support for coldfusion from this month.
I am worrying about hosting on some other best hosting company.
My website is not yet making any revenue so please help me to find cheap price hosting company for my website.
Appreciate your help.
Thanks

I may have came across this post too late, but thought I would offer some help as GoDaddy's cutoff of ColdFusion shared hosting is coming up on 11/29/11.
There are some quality hosts out there that will continue to support ColdFusion, including Hostek, HostMySite, CFDynamics, and my company, The Small Business Authority (we were previously known as CrystalTech and have hosted CF since at least version 5).
Of course, prices will vary, but you should be able to find quality hosting with good support at an affordable price. For instance, our CF plans start at $16.95/month. You can use CF2011 as your promotional code to get four months for free so you can be confident in our hosting and support.
Good Luck!

BPEL security, need help?

Folks,
We need help understanding how the following, that is done in JAVA can be done thru' BPEL
((Stub))._setProperty(Stub.ENDPOINT_ADDRESS_PROPERTY, mywsdlURL);
((Stub))._setProperty(Stub.USERNAME_PROPERTY, myLDAPUSERNAME);
((Stub))._setProperty(Stub.PASSWORD_PROPERTY,myLDAPPASSWORD)
It is a webservice that we are expected to invoke through BPEL. Invoking through JAVA works fine, however we do not know which properties should be used on BPEL to get it to work. We are either getting unable to access end point OR forbidden message. We tried setting these properties on partner link and on composite.
Thank you.

BPEL to invoke Webservice secured with HTTP Basic authentication
the url will be added when you create the partnerlink to your webservice
if you want to use some sort of dynamic partnerlink construction ..you could use :
http://www.oracle.com/technology/architect/soa-suite-series/dynamic_endpoints.html
http://blogs.oracle.com/dasoa/2010/09/11g_dynamic_partnerlink_example.html
with this you can set the endpoint to your own values.
or use something like ant for deployment en replace the endpoint settings at deployment time.

Need help to develop Pythagoras theorem-

Hi i need help to develop proofs 2,3,4
of pythagoras theorems in java as demonstrations
These are applets can anyone help me with it or give me an idea of how to go about developing it -
the site is the following
http://www.uni-koeln.de/ew-fak/Mathe/Projekte/VisuPro/pythagoras/pythagoras.html
then double click on the screen to make it start

Pardon my ASCII art, but I've always liked the following, simple, geometric proof:
     a                   b
---------------------------------------+
|       |                                |
a|   I   |              II                |
|       |                                |
---------------------------------------+
|       |                                |
|       |                                |
|       |                                |
|       |                                |
|       |                                |
b| IV   |              III               |
|       |                                |
|       |                                |
|       |                                |
|       |                                |
|       |                                |
|       |                                |
---------------------------------------+It almost goes without saying that I+II+III+IV == (a+b)^2, and II == IV == a*b,
I == a*a and III == b*b, showing that (a+b)^2 == a^2+a*b+a*b+b^2.
I hope the following sketch makes sense, stand back, ASCII art alert again:     a                   b
---------------------------------------+
|               .             VI         |
|     .                 .                |a
| V                               .      |
|                                        +
|                                        |
|   .                                    |
b|                                     . |
|                                        |
|                  IX                    |
| .                                      |
|                                    .   |b
|                                        |
+                                        |
|      .                                 |
a|               .                  . VII |
| VIII                   .              |
---------------------------------------+
                 a                    bThe total area equals (a+b)^2 again and equals the sum of the smaller areas:
(a+b)^2 == V+VI+VII+VIII+IX. Let area IX be c^2 for whatever c may be.
V+VII == VI+VIII == a*b, so a^2+b^2+2*ab= c^2+2*a*b; IOW a^2+b^2 == c^2
Given this fundamental result, the others can easily be derived from this one,
or did I answer a question you didn't ask?
kind regards,

Need help to open audios attached in a PDF file

Hello
I just need help. I have ordered a reviewer online that has audios and texts in a pdf file. I was told to download the latest adobe reader on my computer. I have done the same thing on my ipad mini. I am not so technical with regards to these things. Therefore I need help. I can access the audios on my computer but not on my ipad.
I want to listen to audios with scripts or texts on them so i can listen to them when i am on the go. I was also informed that these files should work in any device. How come the audios doesnt work on my ipad.
Please help me on what to do.
Thanks

Audio and video are not currently support on Adobe Reader. :-<
You need to buy a PDF reader that supports them. My suggestion is PDF Expert from Readdle ($US 9.99)

Your Touch is working correctly. Currently, without unsupported third party hacks, the Touch has NO disc mode. It will only show up in iTunes.
how do i put programes and games in my ipod touch
Right now, you don't. The SDK is scheduled to be released in Feburary. Then developers will be able to write programs that will be loadable.

With that one, let's try the following procedure.
First, head into your Add/Remove programs and uninstall your QuickTime. If it goes, good. If it doesn't, we'll just attend to it when we attend to iTunes.
Next, download and install the Windows Installer CleanUp utility:
Description of the Windows Installer CleanUp Utility
Now launch Windows Installer CleanUp ("Start > All Programs > Windows Install Clean Up"), find any iTunes and/or QuickTime entries in the list of programs in CleanUp, select those entries, and click “remove”.
Next, we'll manually remove any leftover iTunes or QuickTime program files:
(1) Open Local Disk (C:) in Computer or whichever disk programs are installed on.
(2) Open the Program Files folder.
(3) Right-click the iTunes folder and select Delete and choose Yes when asked to confirm the deletion.
(4) Right-click the QuickTime folder and select Delete and choose Yes when asked to confirm the deletion. (Note: This folder may have already been deleted if QuickTime was successfully removed using Add/Remove Programs earlier.)
(5) Delete the QuickTime and QuicktimeVR files located in the C:\Windows\system32\ folder. Click Continue if Windows needs confirmation or permission to continue. (Note: These files may have already been deleted if QuickTime was successfully removed using Add/Remove Programs earlier.)
(6) Right-click on the Recycle Bin and on the shortcut menu, click Empty Recycle Bin.
(7) Restart your computer.
Now try another iTunes install. Does it go through properly now?
