Help - developing a web-based application and supporting web service

I am in need of creating a web service that provides some reusable components, and then creating a web application that is also a client of the web service. Is it ok to put both on the same application server? Can anyone give me a timeframe for how long it takes to create a web service + web application from scratch? I'm sorry if the questions sounds dumb, I am a newbie to this and am just trying to learn as I go. Thank you for any help!

In answer to your first question, yes. You can have both your web service and web application on the same application server. This is a normal development scenario for lots of applications. As far as a timeframe on how long it takes to create a web service + web application from scratch that depends on the complexity of both the web service and application you are writing. A simple web service and application written by an experienced web services developer could be written in a day. A more complex application could take weeks/months.
Hope this helps!

Exchanging data between a Web Dynpro application and SAP Web Shop

I'll try to keep this as clear as possible:
1) We have the SAP Internet Sales system running, which has a series of Business Object classes and corresponding Backend Layer objects that can return data from several sources.
2) We are able to create our own Backend Layer objects that would return data from a component called IPC, which is a Java component.
3) I would like a Web Dynpro application to retrieve data from this backend layer object, but I am not experienced enough with Java to know if what I want to do is possible. I don't think that I can use JCo, because I am trying to get a Java component (class?) in Web Dynpro to access a Java class remotely.
4) I think I am asking is this: is there a way for a Java to Java connection to be created, much like Web Dynpro can use JCo to connect Java to ABAP systems?
If this is a glaringly obvious question to Java programmers, my apologies!

Somebody on another forum recommended using RMI. Which would be the better option in terms of ease of implementation?

Registering the Web based application as a Partner Application

Good day
I went through the suggested documentation of registering a
web based application as a partner application of the SSO Login Server.
I installed the SSOSDK.JAR and went through the demo application (JSP Demo)
which consists of the following programs :
papp.jsp
ssoinclude.jsp
ssoEnablerJspBean
SSOEnablerBean
SSOSignon
As per the technical documentation,I register this demo application as a
partner application.
1 - The source code of the papp.jsp checks for the existence of the user
through method of ssoEnablerJspBean [getSSOUserInfo(request, response)] which
calls method of SSOEnablerBean [getSSOUserInfo (request, response) and this
method calls getUserInfo(p_request) of SSOEnablerBean (the same program) to
check the existence of the application cookie.
2 - If it doesn't exit , it redirect it to the SSO Login page for user
authentication.Once the user is authenticated, a SSO login cookie is created on
the client's browser and redirects back to the SSOSignOn.
3 - The SSOSignOn program creates the application cookie and redirects back to
the entry point of the demo application which is papp.jsp.
My Questions are as follows :
1 - Instead of creating a session object within my web based application to hold some
information used between the different pages, can I define them in the
application cookie? kindly advise? Is there any limitation for the length of
the application cookie? If yes, what will be the risk?
2 - The SSOSignOn program is calling a method in the SSOEnablerBean
[setPartnerAppCookie(response, request). Within this method , it is retrieving
the parameters values of the request object as :
request.getParameterValues("urlc")[0];
What is the role of this [urlc]? Is it hard coded? Can I change it?
3 - In order to ensure that I am still dealing with the same user, shall I put
the above security check procedure on each page of my weeb based application? Kindly advise?
Thanks in advance for your prompt feedback
regards

Dear Paul
I think there is a misunderstanding regarding the last correspondence.
I am talking about the customized home page of the PORTAL and not the home page of my web based application (JSP) .So in this case, Am I able to use the customized home page which contains a login portlet instead of the default Login page of the SSO Login Server.Kindly advise!!!
On the other hand, I am facing a problem during the surfing of the web based application.
The web based application consists mainly of two packages :
Package I : Bank.counter which contains a set of jsp pages.
JSP_HOME_COUNTER (MAIN PAGE WHICH CONTAINS 2 FRAMES)
JSP_LEFT_FRAME_COUNTER
JSP_MAIN_FRAME_COUNTER
JSP_MAIN_FRAME_COUNTER_DETAIL
Package II : Bank.portfolio which contains a set of jsp pages.
JSP_HOME_PORTFOLIO (MAIN PAGE WHICH CONTAINS 2 FRAMES)
JSP_LEFT_FRAME_PORTFOLIO
JSP_MAIN_FRAME_PORTFOLIO
Please note that the SSO classes are residing under the first package.
As agreed on in the third question, I am including in each page of my web based application, a security check procedure as follows :
<%@ include file="ssoinclude.jsp" %>
<%
if(usrInfo == null)
response.getWriter().println("<center>User information not found</center>");
else
my jsp code.......
%>
Please note that all the jsp page of the portfolio package are pointing to the SSO classes as follows :
<%@ include file="../counter/ssoinclude.jsp" %>
<%
if(usrInfo == null)
response.getWriter().println("<center>User information not found</center>");
else
my jsp code.......
%>
Once I invoke the JSP_HOME_COUNTER , it will render the JSP_LEFT_FRAME_COUNTER page and
JSP_MAIN_FRAME_COUNTER page which invokes the SSO Login page. Once the user has been authenticate, the result of the JSP_MAIN_FRAME_COUNTER is rendered successfully. The result contains an hyperlink to the
JSP_MAIN_FRAME_COUNTER_DETAIL page. As the user has been authenticated , this page is rendering automatically the result without displaying the SSO Login page. (Perfect as of now!!).
Once I invoke the JSP_HOME_PORTFOLIO from the JSP_HOME_COUNTER, it runs the security procedure without any rendering of the SSO Login page (fine!!) but redirects me back to JSP_HOME_COUNTER instead of rendering the result of the JSP_HOME_PORTFOLIO.
please note that the m_requestUrl variable in the SSOEnablerJSPBean class has been assigned the folowing value : JSP_HOME_COUNTER
Kindly advise .

Developing Web based applications using developer 6.0

How best i can use developer 6.0 as a web based application. I

Yes, it's possible and it runs.
You will need:
- Application Server 4.0.7 or above (with 4.0.7 without patch,
do not install it on Win NT with SP4, it doesn't run
- Developer Server (may be it is not on your distribution CD for
Developer, but you can download or order it from OTN)
- JInitiator (the Oracle Java PlugIn, also available from otn)
for your end user's browser
Tip:
look very carefully at the documentation AND readmes. Also, if
you do this job for the first time, be prepared for some days of
work before your first form runs as a java applet...

Authentication between Single Sign-On and Web based applications

Hi everyone,
I need to create a way in Portal 10g (10.1.2.0.2) that allow me to do the following:
Once the user is logged on Portal (against Single Sign-On - SSO) he doesn't need to retype his username/password when he access a web based application throught the portal, in my case, an ASP application (not .NET, just ASP).
I made a test creating a External Application in SSO and after publishing this portlet (external application) inside portal.
It worked, BUT I was prompted to inform username/password to log on the aplication.
So, the user end up entering his password twice.
Does anybody know a way to acomplish this task?
The documentation I'm researching is:
Oracle Application Server Single Sign-On
Administrator's Guide
10g Release 2 (10.1.2)
B14078-02
Oracle Application Server Single Sign-On
Security Guide
10g Release 2 (10.1.2)
B13999-03
Thank you very much,
Diogo Santos.

have figured out how to secure any HTML, ASP, PHP, CFM, etc. web page again Portal / OID using the PDK toolkit.
Using AJAX (Asynchronous JavaScript and XML) and one Oracle Stored Procedure just adding a simple Javascript call to any HTML, ASP, PHP, etc. web page can secure it via Oracle SSO (OID). Access to any secured web page will require that it to be linked from an authenticated Portal session or a page opened in an authenticated Portal session.
This process can be easily modified to add in group security etc. This is just my starting point.
1) Create a stored procedure
# Make sure it has access to portal.wwctx_api.is_logged_on
CREATE OR REPLACE PROCEDURE login_ajax_check (
display_error IN number default NULL) AS
BEGIN NULL;
If portal.wwctx_api.is_logged_on = false then
htp.prn('DENY');
ELSE
htp.prn('ALLOW');
END IF;
Exception when others then htp.p('DENY');
END;
2) Use this Javascript in any page you wish to secure.
<-- Begin Paste Here -->
<script>
var allowgo=2
function ajaxCallRemotePage(url)
if (window.XMLHttpRequest)
// Non-IE browsers
req = new XMLHttpRequest();
req.onreadystatechange = processStateChange;
req.open("GET", url, false);
req.setRequestHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT");
req.send(null);
else if (window.ActiveXObject)
// IE
req = new ActiveXObject("Msxml2.XMLHTTP");
req.onreadystatechange = processStateChange;
req.open("GET", url, false);
req.setRequestHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT");
req.send();
else
return; // Navigateur non compatible
// process the return of the "ajaxCallRemotePage"
function CheckPortal()
ajaxCallRemotePage('[Your page calling the procedure from above]');
function processStateChange()
if (req.readyState == 4)
if (req.status == 200)
if (req.responseText.substring(0,4) == 'ALLO')
allowgo = 0;
else
allowgo = 1;
function doPage()
if (allowgo==1)
window.location='[Your login or error page]';
CheckPortal();
doPage();
</script>
<-- End Paste Here -->
That's it!!! Super easy. It works great too.

Dear sampathdevunuri kumar,
You may develop the addon based on SDK DIServer for required function.
The DI Server is an extension of the DI API and supports all its objects. It is intended for high-volume data integration, where numerous client connections must be managed simultaneously and optimized for speed. It is also suitable where Web-services architecture is preferred.
Please refer to SDK help and SDK DIServer sample for more information.

Client/Server to Web-Based application Conversion

Hi! Everyone,
I have couple of questions for you guys.
Our Client had recently upgraded Forms 4.5 to 6i to move from Client/Server based application to Web based application.
They are using Forms Server 6i Patch Set 1, OAS 4.0.8.1, Windows NT Service Pack 5 and Oracle 7.3. They are facing the following error every now and then, when they run the forms,
"FRM-92100: Your connection to the server was interrupted. This may be the result of a network error or a failure on the server.You will need to re-establish your session."
Please let me know what might be causing the above error. The only problem i can think about might be Oracle 7.3. If i am right only Oracle 8 and above supports Forms 6i.
Can anyone let me know some tips and/or techniques to upgrade Forms 4.5 to 6i. If there are any important settings/steps which we might have over looked during the upgrade, please list them.
Any kind of help is greatly appreciated.
Thanks,
Jeevan Kallem

Most of the code is use with no changes at all.

Conversion of forms5.0 to web based application

dear folks,
i have an existing application which runs on forms 5.0. i want to
convert it to a web based application. i do not want to rewrite
the scripts.if some of you could tell me the details about how to
go about it.

I am not sure if there is any tool to do that.
You can delete WebSphere specific xml files from ear/jar and open it in Weblogic's builder tool. Weblogic Builder is a GUI tool. Helps you assign values for deployment parameters, Transaction attributes, JNDI names and so on. Then you can generate deployment descriptors. Subsequently you can modify the descriptors as and when you want.

Web Based Application Single Sign on With Enterprise Portal

Good day Developers,
My question is really a two part question so forgive me in advance for asking in one post as I think they are relative to each other. My project is currently exlporing the creation of functionality that will allow the following:
1. We want to allow a secure Web Based application possessing the abilitiy to auithenticate the user into Enterprise Portal and by passing the login screen to get to a landing page/iview in our Enterprise Portal instannce.
2. We want the abilitity to perform a check of the user and create the user in the enterprise portal on the fly if they do not already exist.
So far in my research I've come across tools and white papers mentioning the use rof oAuth and OpenID. Is that the right way to tackle these two items. Thanks for your help in advance.
JD

Hi
1. You can do SSO between you application and portal using Verisign or third party authentication tool. I am not pretty sure how landing page and all will work as you mentioned.
As portal is web based, you can deply your application in portal server. So that you will not need any other authentication tool.Also you can save effort , cost.
2. By deploying application in portal also you do not have to concentrate on User management, which is itself a huge effort you have to put. Else you can go for third party tools like Identity management or ADS.

My firefox crashed when upload file on our web based application. This happen on two PC, even during firefox safe mode the problem still exist. But the problem

Dear All,
My firefox (version 23 on win 7) crashed when upload file on our internal web based application. This happen on two PC, even in firefox safe mode the problem still exist. So, my first conclusion the problem nothing to do with extension. here the crash ID https://crash-stats.mozilla.com/report/index/81220865-36c0-4e10-a484-6d27e2131023 and https://crash-stats.mozilla.com/report/index/86d2b779-9730-4d2c-b276-a86d42131023. I wonder if this happen because jquery modul in our web based application. But when I tried on my laptop, the problem dissapear. I tried to replicate same situation on different server, I mean I put the exact same application source to other server, never meet the same problem. Thus, I suspect may be it related to antivirus that installed in our network which is kaspersky. I am googling, never meet the clue.
If you meet the same problem, please help me.
I am so sorry for my poor english.

The crashes are a problem with the winhadnt.dll file (OCular Agent from TEC Solutions Limited) as you can see in the crash reports.

What technologies to use in web based application...??

Hi,
I have to develop a web-based application that will be used to display configured tests to user as well will allow user to add new tests and modify/delete already configured tests. What technologies shall i use to develop this application. And what will be fast to learn.
What is your opinion on applet-servlet approach here.
Please suggest.
Thanks,
Deepak

What you've got sounds good.
If you're not going to build EJBs then you probably don't need JBoss.
Tomcat is the servlet engine for JBoss so you're getting the same thing but lighter by just using it.
The important thing is to make sure you have a nice separation of concerns. If you separate all of the database access by creating data access objects (DAO) objects that return plain old Java objects (POJO) then you can, if you choose, easily swap in Hibernate or another ORM Tool.

Probably a wap gateway is obstructing the correct transmission
Therefore, might be your network blocking the application to exchange and transmit datas.
Maybe Nokia's are much easy to handle (manipulate) than your previous phone.

Web Based review and Approval

Hello,
I have found some resources in apple website regarding the FCSvr web based review and approval, it is working with Ruby Rails. One thing I am testing with this is incorporating the website view to iPhone, I used H.264 video format for iPhone but it still seems not playable to the device. Thus anyone have tested this one?
Thanks,
William

I used Apple's own "Export for Web" in QuickTime Player to get started on the code to deliver for the iPhone. I haven't tried incorporating it into the Rails app from the developer's example, but it is a good place to start for working out the code to feed the iPhone with multiple bitrates. You can also look up Apple's MakeiPhoneRefMovie sample code.
Alternatively you can use HTML5's <video> tag, for which Apple provides some direction.

SharePoint 2013 and IE 11 issue - While creating a Web Part Page and Editing Web Part Properties

I tried to edit a Web Part in SharePoint 2013 using IE 11 but I did not see the Edit Eeb Part dropdown menu at the top-right corner of the web part. Then I tried to create a Web Part page and I get the following error.
Cannot create a Web Part Page with the current browser. Browsers that support the creation of Web Part Pages include Microsoft Internet Explorer 7.0 or later, Mozilla Firefox 3.0 or later, and Apple Safari 3.0 or later
Strange !!! My web browser is IE 11.
I tried the above two tasks in Google Chrome and worked fine.
Solution:
I added the site url to local intranet zone in IE 11 and I am now able to add Web Part Page and Edit Web Part in IE 11.
