How to create a servlet in PAR Application

Hi Experts,
I want to create a servlet in PAR application. This servlet should be capable of accessing the functions of other java files included in PAR Application. Servlet should be capable of accessing the functions say doContent(req, resp) of any class of PAR application.
Is it possible to create Servlet in PAR application?
I created one servlet but unable to declare its information in Deployment Descriptor.
Because the deployment which is provide ie portalapp.xml doesnt allow us to write tags like <servlet-name>, <servlet-mapping>, <url-pattern> etc. These are necessary for declaration of servlet.
So how can i write a complete working Servlet under PAR application?
Please help and replies will be appreciated.

Hi,
Depending upon your usecase there are different ways to implement this logic.

Hi Pankaj,
I don't think it is possible to write Servlet in portal applications.
I guess in Portal Application Projects we can develop portal components and portal services only.

Please update your forum profile with a real handle instead of "914824".
When you have a problem you'll get a faster, more effective response by including as much relevant information as possible upfront. This should include:
<li>Full APEX version
<li>Full DB/version/edition/host OS
<li>Web server architecture (EPG, OHS or APEX listener/host OS)
<li>Browser(s) and version(s) used
<li>Theme
<li>Template(s)
<li>Region/item type(s)
With APEX we're also fortunate to have a great resource in apex.oracle.com where we can reproduce and share problems. Reproducing things there is the best way to troubleshoot most issues, especially those relating to layout and visual formatting. If you expect a detailed answer then it's appropriate for you to take on a significant part of the effort by getting as far as possible with an example of the problem on apex.oracle.com before asking for assistance with specific issues, which we can then see at first hand.
I am going to have over 50 buttons in a page, Why? This would be a most unusual UI paradigm. I've never seen such a page, which suggests that whatever you want to do is normally done another way. Please explain the requirement in more detail.
just wanted to know if its possible to do something like this in java.
Java is not used in programming APEX UI behaviour. Java and JavaScript may share initial syllables, but they are not closely related.
It's possible to achieve a great deal in JavaScript, but a clear definition of the requirements is necessary. Do you mean the buttons should be dynamically generated? If so, yes, this is possible in JavaScript. What would drive the process?
Also, i would like to have dynamic action on it, for example, when the button is pressed, fill a string of text into other items(text field) within the page. Without more detail its not possible to make any specific suggestions. For example, I certainly would not want to create 50+ individual dynamic actions relating to different buttons.

Thanx for your reply's
If I understand the tutorial correctly I should do
something like this to start the map:
Map<String, myClass> myMAP = new HashMap<String,
MyClass>();
and something like this to add a new instance of the
class every time:
myMAP.put(myString, new myClass());
So this would result a link between the Strings and
the instance of the Class?
Thanks
Message was edited by:
JasperLevinkyep. the String is the key, and the MyClass instance is the value. to get the value out of the map, use map.get(key)

Go to Administration > Dimensions > Select Dimension > Select the member to want to assign acccess filters to :- Assign Access
Repeat process for all access permissions.
If there is a lot of permissions to set you could use a utility :-http://download.oracle.com/docs/cd/E12825_01/epm.111/hp_admin/ch03s07.html

How to create and delete an Endeca application in Windows

HI,
can you please help me in ,
how to create and delete an Endeca application inWindows machine not in Linux Machine.
Thanks.....

Hi,
Steps to create an Endeca Application are clearly given in Getting Started Guide.
http://docs.oracle.com/cd/E38680_01/Common.311/pdf/GettingStarted.pdf (Chapter 6 : Deploying a Reference Application)
If you want to create an endeca application so as to integrate with Product Catalog system such as ATG using ATG 10.1.1 or above , then create an endeca application using the discover-data-catalog-integration reference application. Steps for doing this are documented in ProductCatalogDTGuide
http://docs.oracle.com/cd/E38679_01/ToolsAndFrameworks.311/pdf/ProductCatalogDTGuide.pdf (Deploying the Product Catalog Application)
To delete an Endeca Application that you have created in Windows/linux
1. Navigate to the control directory of the application that you want to remove and execute the script
runCommand.bat --remove-app (Removes the provisioning information with EAC admin console)
2. Remove the instance configuration files for the application using the emgr_update command line utility
emgr_update.bat host localhost:8006 app_name My_app action remove_all_settings prefix My_prefix
3. You can then explicitly delete the directory in the Endeca_apps directory where you have initially created your application.
If you are using discover-data-catalog-integration, you can remove the CAS Record Store Instances by navigating to CAS/bin directory and executing
./component-manager-cmd.sh delete-component -n {YOUR_APP_RECORD_STORE_NAME}

How to Create Listbox in a JSP Application

Hi.
I'm new to JDeveloper. Can someone show me how to create a Listbox (that gets it's values from a database table) in a *.jsp form? This listbox is linked to a database table field. I'm not using BC4J nor EJB. I've created a JSP application with ADF using a Model1 (or MVC pattern) architecture -- which I based on the JDeveloper10i tutorial (http://otn.oracle.com/obe/obe9051jdev/ADFmodel1/ADFmodel1.htm). I've tried using render on the field in the view object entity, refresh the Data Control Palette and then drag the table view entity to a *.jsp page as input form. But I can't see the field in the form being displayed as a list box.
Please help.
thanks,
christina

Hi Shay.
Thanks for the quick reply. Sorry for the misuderstanding but I have no clue on terminology used in JDeveloper. The "view object" entity I was referring to is the "<TableName>View" view object (e.g. EmpView) under the Model->Application Sources->Mypackage folder where the "<TableName>" entity object file also resides. I think I'm using the Business Component bec. I have this step in the tutorial that I based my application on.
I have trouble following the tutorial link you gave me (for the ADF Business Component Popup list) bec. when I select the table field in the "Data Control Palette" Panel, the only values I see in the "Drag and Drop As" poplist are "Value","Label","RenderValue" and "Input Render". I can't see the type "Single Select List". Do you why is that?
thanks,
christina

The SAP Business One SDK Help Center documents how to package your solution. I would recommend that you start with reading the documentation here under the subject of "Package and Deployment". You can also download the Business One Development tools (B1TE) from this site which will assist you with packaging your add-on.
