Integrating existing Web application with Oracle Portal

Hi,
I have an existing application which is purely written in servlets and which is in use for quite some time. I have a requirement now of moving this application onto the Oracle Portal.
I was just wondering if we have any quick meanse of doing this or we have to re develop from scratch in oracle Portal server(ByDefining page, Page templates..etc).
Advance thanks for your help
Thanks
Sreedhar

What do you mean with "moving this application onto the Oracle Portal"?
The best expedite way is use in the portal a LINK that direct your users to the actual app.
Another quick thing you could do is use the IFRAME TAG (only works in IE). This way you can embed your app in Portal (show it in some area in portal)
Then comes the complex things:
- You can activate SSO to your applications ( which is not THAT difficult)
- You can PORTLATIZATE your app, this doesn't means that you have to rewrite all, but still you need to write in a "Oracle Java Way" some thing to get it work..
You can see this link if you're using portal 10.1.2:

  • Integrate Web application with Oracle BPM

    Hi,
    Can you guide me in achieving the following scenario:
    1. Integration web application with oracle BPM
    Say, I have a application where I need to trigger an event to call Oracle BPM. For ex: On click of submit button call the Oracle BPM workflow to do some process and then revert back to the same application with an alert or status message. Please let me know the steps to acheive this.
    Thanks
    ST

    Hi,
    I take from this description that you currently have your Web Application and you would possibly like to trigger or create an instance into an OBPM business process. If this is the case, you have several options available here:
    a) Use PAPI (Java API).
    b) Use PAPI-Ws (SOAP API).
    c) Use some sort of communication channel that the process is implemented to listen (for example a JMS Queue or Topic).
    For the first 2, you can try to take a look into the official Documentation page for OBPM through this link: http://download.oracle.com/docs/cd/E13154_01/bpm/docs65/index.html (Check the For Developers section).
    If I have miss interpreted your question, please do not hesitate to provide more details.
    Cheers,

  • Integrating existing UI application with BPM workflow

    Hello ,
    We want to integrate the oracle BPM workflow with existing UI application (developed in JSP) , Question is how do i map human task from BPM process to existing UI JSP pages/modules .
    a sample module from application is like below -
    Application has two roles - Operator and Approver and UI pages for both roles are already created .
    Now from first UI page (using Operator role ) user will submit a request and then it should go and invoke the BPM workflow .I can do this using web service (BPM process exposed as web service ) .
    Now next step is where i have a problem - Assigning this request to another role - in BPM workflow i can create a Human task and assign role there but how do map
    this HT to my existing UI pages .
    Let me know if i am not clear on question .
    Thank You
    Rupesh
    Rupesh

    Hi Rupesh. If you want to integrate the oracle BPM workflow with existing UI application, you should see the Oracle SOA Suite 11g Handbook, in the Chapter 20. I'm sorry for don't gieve you the link. I found that book very helpful. Regards.

  • SharePoint 2010 - Create new site collection in existing web application with different existing content DB

    I have a SharePoint 2010 root level site collection SC1 in web application WEBAPP1. I want to create copy of that site collection in same web application WEBAPP1. Apart from Import/Export, Restore/Backup options, will following approach work? If yes , how?
    I took backup of content database of web application.
    Restored database with different name
    Mounted Content database to this WEBAPP1 by assigning new ID to DB
    Created new site collection by using this newly mounted DB
    Site collection gets created successfully but content does not appear.
    Please guide if i can achieve desired functionality by using this approach.
    If this helped you resolve your issue, please mark it Answered

    It is because the Site GUID is identical, and each GUID can only be present on the farm once. You can use Backup-SPSite/Restore-SPSite (which is full-fidelity, unlike Export-SPWeb/Import-SPWeb), which will generate a new GUID for the restore Site Collection,
    even in the same Web App.

  • Integration of J2EE application with weblogic portal

    Hi guys,
    I have an application hosted on an iplanet web server. This application uses servlet 2.2, jsp 1.1 of J2EE platform.
    And I have a microsoft application running on .NET platform.
    I want integrate above 2 applications into webloigc 8.1 portal. What are the different ways in which i can do this and where can i find specific material on this.
    advance thanks for your help
    gopaluni

    Basically I am saying that your options are
    1. Screenscraping the apps into portlets
    2. Using SSO to login to the apps, but keepin them separate
    3. Using Web Services to consume parts of the apps and exposing those as portlets
    For our application we do 2 and 3. In many cases we just create portlets that represents views into other j2ee apps. When the users click on something, we launch the j2ee app in a popup browser. The users are already signed on, and taken to a specific detail page, add page or something within the app directly.
    Hope this helps.

  • Developing Rich Web Applications With Oracle ADF Tutorial

    Using J Developer

    In Part 3 Step 2.2 In the query.jsf page the tutorial reads
    2 Still in the Properties window expand the Behavior node and set the AutoSubmit property to True.
    The problem is the only option listed under Behavior is Landmark. The other properties are not shown including the
    AutoSubmitt which I need to set to True.
    Any Ideas on whats going on?
    Thanks in advance!

    Hi,
    would have been of great help if you provided the link to the tutorial (just for next time). You can see that the focus in the screen shot is on the salary field. The screen shot below then shows the behavior property palette and clearly you can see that there is an autosubmit property. Chances are that you did not put the cursor focus properly on the input text component or the Property Inspector did not refresh. In the latter case, close and re-open the property inspector or select the input text component in Structure Window

  • Question about Tutorial: Developing RIA Web Applications with Oracle ADF

    I'm learning about ADF and JDeveloper:
    According to the tutorial, after I've bound the data controls for the top right panel and bottom right panel, the bottom panel should always show the employee selected from the collection above.
    However when I do the instructions, the employee information in the bottom right employee area never changes regardless if I select a different employee in the top panel collection.
    I can't figure out why the top and bottom panels don't link together. I'm using the same View in both panels....
    I'm using Build JDEVADF_11.1.1.1.0_GENERIC_090615.0017.5407
    Thanks in advance for any suggestions!
    Rob

    The mechanism that synch the two section of the page is called partial page rendering.
    It should work if you follow the instructions in the tutorial, but if it doesn't it is quite easy to fix:
    In the structure pane, select the Form component that surrounds the employees update section
    Then look at the properties inspector for a property call partial trigger
    Click the arrow on the right of it to select edit - and navigate your page hierarchy to choose the table component.
    An example is here:

  • [Problem]Registering "External Applications" in Oracle Portal

    We want to register an external application (simple HTML based login application) with Oracle Portal 10.1.4. We followed the steps documented and registered the external application. We did provide the necessary credentials and checked the remember credentials check box.
    We added the External Application Portlet which provides a link to the added application. However, everytime we click the link , instead of automatically logging into external application , we are shown the external application login screen.
    Our environment: Oracle 10.1.4 Portal ; Oracle 10.1.2 Appserver
    Appreciate any help to solve the problem.
    Thanks

    Hey 619948:
    These can be tricky to track down. Typically, there are 1 or more form fields missing from the external application that the actual application needs to log you in. Here's the flow I use to setup external apps.
    1) Go to login page of the external app and view the page source
    2) Find the URL in the action address of the <FORM tag or in the JavaScript used for submitting the form
    3) Find every form input including <INPUT, <SELECT, etc and note their names and their values (if any). This includes hidden ones
    4) The tricky part -- try to make an educated guess as to which fields are required and which ones are optional. This is not always obvious
    5) Setup your external application with the Action URL as the URL, the username and password fields where indicated and adding in any extra fields identified in step 4
    If that still doesn't do the trick, I use the Web Developer plugin for Firefox to change the POST (if that is what is used for logging in) to a GET so I can see the exact fields being submitted on the application's login page. Sometimes, it may be an obscure button like submit=submit.
    Finally, some applications just don't play well with externally logging in. This is one of the cases where it really isn't Oracle Portal's doing. Some apps just have so much coding and scripts etc. on their login page that you just can't login except through thier page.

  • Portal Integration of an existing Web Application

    Dear all,
    we are preparing for the pbnw certification. Our way is to deploy our existing web application on the J2EE engine and make it accessible via the portal, i.e. where are taking the certification scenarios J2EE-DEP and BP-EP.
    Up to now, my idea is to integrate the web surface of our application into the portal as far as this is possible without too much effort. Alternatively it would be possible to access our application via an URL-iView however to my feeling this is not a real integration. Did I get things right assuming that would meet the requirements for pbnw certification?
    I read that it is necessary to follow the portal's look and feel by applying SAP's CSS. Does anyone know where to obtain these? And what is the easiest way to replace the currently used stylesheets by them?
    Millions of questions...
    Thanks a lot!
    Regards,
    Angela Grüner.

    Dear Angela
    Please have a look at the following Weblog link which gives a detailed description of the method to create a URL iView using Application Integrator:
    /people/markus.pfeffer/blog/2005/12/14/integrating-your-web-front-ends-into-the-sap-enterprise-portal-using-the-application-integrator
    If you adopt this method to create the URL iView, then it meets the requirement for EP-BP Certification.
    The blog also includes an example of HTML code with applied SAP CSS. Please go through this section to implement EP look and feel.
    Hope this helps!
    Regards

  • Integrating Web Services Manager with Oracle Portal and SSO

    Hi,
    I wanted to throw this out there and make sure I was on the right track and also if somebody can point me to some resources online that might help. Basically, we have OWSM acting as a Gateway securing some web services. Oracle Portal is integrated w/ Oracle SSO (as well as using OID). What is the best way to pass the credentials to the OWSM from the Portal for authentication purposes? I believe using SAML voucher token is the way to go, but I'm not positive. Has anybody done this before and if so, what methodology did you use? I'm assuming since using SSO, we don't necessary want to also pass in the password.
    Thanks,
    Nathan

    I have noticed that nobody has same kind of situation and this is not intresting question. Still we have same problem and I have heard many oracle employee saing that this behaviour is wanted situation. In our kind of virtual host enviroment it would be nice to choose behaviour of Single-sign-on server and I request oracle support to find out ways to enable this option... I would be pleased if some oracle development would say opinion about this mater. Waiting for ideas.

    1)Portal is an integrated component of 9iAS. You need to download all of 9iAS and select the minimal install option.
    2)We haven't tested this configuration, but as long as you set up apache appropriately to use different ports than the existing software it should work.
    3)Portal requires 8.1.6.2 Enterprise edition or 8.1.7 Standard edition. Personal Edition will not work.

    Afternoon friends,

    Hello
    Couldn't see my previous post... so here it is again
    We have integrated Apex into Oracle Portal
    Here's how we did it.
    In the portal page, we have created an Element region with the following code:
    <script language="Javascript">
       <!--
       function changeIframeHeight(){
          var ifrmObj = document.getElementById('apexIframe');
          if(ifrmObj) {
             if(navigator.appName=='Microsoft Internet Explorer') { //IE
                ifrmObj.height = ifrmObj.contentWindow.document.body.scrollHeight+20;
             else {
                ifrmObj.style.height = ifrmObj.contentWindow.document.body.offsetHeight+50;
       //-->
    </script>
    <p><iframe width="100%" height="500" frameborder="0" onload="javascript: changeIframeHeight();" src="/pls/apex/f?p=115:10" marginheight="0" marginwidth="0" name="apexIframe" id="apexIframe"></iframe></p>You just have to make sure that the name and id of the iFrame and the elementId in the javascript are the same.
    And change the SRC so that it point you application.
    Hope that helped you.
