Calling Portlet from URL

Can a report portlet be called from an item URL ?
Any idea ...

Hi,
I guess you are trying to use the URL component under the Applications tab.
You can specify any URL here ,it can be any external site or even a URL that is equivalent to a RUN ,RUN PORTLET of a component or a page URL.

Calling portlet from a normal web application

I have the following question:
I would like to deploy portlets on Oracle Portal and "call" them programmatically from a home made web application running on the same Oracle Application Server where the portal runs.
As I am running my web application on the same server I would like to avoid WSRP and SOAP calls.
I am aware of the existence of the new Web Center and the possibility it gives to include portlets in web application ... but I cannot use the Web Center for now mainly because of licensing problems and application server versions.
Is there an API (Java, PL/SQL or anything else) allowing to "call" a portlet deployed on Oracle Portal ?
Thanks for the help.

Hi,
Well, I did my JSP pages doing selects to OWF tables and OWF java APIs. I used owf pl/sql procedures as my reference. For example, I need to know how to create actions buttons. I looked at wfa_html procedure and looked for how it was doing that.
Any doubts just ask,

Calling portlet from an image item

I have two image items and I want to call two report portlets such that If I
click on ImageA, it should call first report portlet and If I click on ImageB,
it should call 2nd report portlet on the same portlet reigon. I mean it should
hide and show the two report portlets on the same page and same region. This is
what I have done so far :-
(1) Created a content area
(2) Created a category
(3) Added two image items in that category
(4) Created two reports and published as portlets
Any help would be much apprecited.
Thanks

Hi
But the values you have given are hardcoded what if i want to capture the value on which i click and then pass it as a parameter.
My problem is i have a chart in a dynamic page when i click on the deptno i want to call the same chart by capturing deptno and passing the value in the call to the chart as an argument.

How to call portlet from image item

Hello,
Here is the use case:
I have a feedback form portlet. I want users to click on an image and open a popup window with feedback form portlet in it.
How can I do this? Is this possible?
Thanks,
-Dong Chen

Hi Dong Chen,
As mentioned in the other post, you could just use a simple jsp page to do the job. But if you would like to use a portlet instead, then you will have to construct a link to the portlet's details mode <refer to the documentation for details on this> and use that link for invoking the portlet in the pop-up. The only issue here is that the styles dont get rendered, so you might want to include a reference to the style sheet in your portlet code.
thanks,
Harsha

URL based portlet from external application

Hello,
I'm trying to integrate a forms 6i patch 10 application into SSO.
First, I created an external application, passing it the correct parameters.
Everything went ok, and I can successfully call it by entering
"Administer Enternal Application" link on Oracle Portal.
Now I want to make a portlet from this external application. For that I'm
using PDK URL Services. So I reused the urlexternalauth provider which is
included in the latest PDK. The provider.xml is included below. I successfully
registered the provider, by following the wizard "Register Portlet Provider" on
Oracle Portal. But when I call the portlet, the html startup file for the form
is base.htm. When I call the external application through the "Administer Enternal Application" link,
I get the right html startup file, which is basejini.htm.
So I need basejini.htm called from the portlet, and not base.htm.
Thanks,
Andri.

Andrea,
Could you tell me if FORMS 6i authentication process is based on cookies? The reason being, URL based portlets SSO feature is primarily driven by External Application's cookies, which act as authentication tokens. Once a valid user information is submitted to the External Application, cookies (if any) are received and stored so that they can be re-used in further connections. A typical flow of events can be summarized as follows :
At provider level :
1. Connect to External Application.
2. Submit user information to url specified by External Application's login URL.
3. Fetch cookies
4. Store them for future use.
At portlet level :
1. Read cookies fetched through provider, pertaining to this portlet.
2. Open connection to url specified by <pageUrl> tag in provider.xml
3. Read content and display in the portlet.
From the provider.xml, I can see that we are trying to show content given by http://venezuela.rjo.br.odebrecht.com:7780/servlet/f60servlet servlet, which has two parameters called {config and database}. This makes the resulting URL as http://venezuela.rjo.br.odebrecht.com:7780/servlet/f60servlet?config=icorp&database=venezula. I guess when this URL is accessed directly, FORMS servlet will redirect the user to base.htm file. Important point to note here is that when URL based portlet makes connection to the above URL, user information is not directly sent along with the request. Instead, cookies fetched from External Application, if any, are sent. But when the same application is viewed through portal's External Application, user information is directly submitted to the login URL. So, before deciding on something, it is important to know how different is the loginURL specified through portal's External Application details, from <pageUrl> of URL based portlets?

Calling Webservice from Adobe form - Webservice URL Issue

Dear Friends,
I have developed a webservice and calling it from an Adobe form. I have downloaded the WSDL file from tcode SOAMANAGER. When I create a data connection from the Adobe form I use this WSDL file and the form elements gets created automatically and I drag and drop them into the form. The issue is when I click on the Submit(Execute) button the Webservice URL is always pointed to the client from where the file was downloaded and its hard-coded ( for example if i download the wsdl file from client 300 then the URL would be http://<location>/sap/bc/srt/rfc/sap/z_web_getmat/300/z_web_getmat/z_web_getmat). So if i execute the form from client 200 its not working. How to make this URL dynamic so that the webservice gets executed from the client from where this form is called. Please advice.
Regards
Sapient

Hi,
You have to handle it in your form on submit button calling the web service:
Write below java script code at submit event to change the URL at run time:
var tempsoapAddress = xfa.connectionSet.DataConnection.getElement("soapAddress").value;
var tempwsdladdress = xfa.connectionSet.DataConnection.getElement("wsdlAddress").value;
var ServerPath = body.systemConfig.system.rawValue;
var client = <Get Client from a data attribute>
var Soap_PreServerPort = "http://";
var Soap_PostServerPort = "/sap/bc/soap/rfc?sap-client=";
var SoapAddress = Soap_PreServerPort + ServerPath + Soap_PostServerPort + client ;
var Wsdl_PreServerPort = "http://";
var Wsdl_PostServerPort1 = "/sap/bc/soap/wsdl11?services=ZBAPI_PO_CREATE2&sap-client=";
var wsdlAddress = Wsdl_PreServerPort + ServerPath + Wsdl_PostServerPort1 + client ;
xfa.connectionSet.DataConnection.getElement("soapAddress").value = SoapAddress;
xfa.connectionSet.DataConnection.getElement("wsdlAddress").value = wsdlAddress;
xfa.connectionSet.DataConnection.execute(0);
xfa.connectionSet.DataConnection.getElement("soapAddress").value = tempsoapAddress;
xfa.connectionSet.DataConnection.getElement("wsdlAddress").value = tempwsdladdress;
xfa.connectionSet.DataConnection = null;
Change the variable wsdlAddress as per your requirement. The above code is just a sample.
For getting the client pass it in a datasource variable attribute at time of downloading the form. At time of submit get the value of that variable and use it to form the url.
Regards,
Vaibhav

Secure AJAX calls made from a JSR 168 portlet

I am investigating methods to secure AJAX calls made from a JSR 168 portlet to a servlet using the Direct Web Remoting framework (DWR) and Weblogic Portal. The portlet can have more than one instance and different entitlements depending on the desktop it is available from. The Portal has several desktops and does not require the user to authenticate for some of the desktops.
So far the only method I have come up with is to pass a token from the portlet to the servlet which indicates the entitlements the user should have to access the documents from the portlet and check in the servlet if the User has the appropriate global roles to access the documents.

no , that doesn't work, the token passed can be modified by a malicious user (unless the token is random or signed)
You need to store the desktop(s) the user is on in probably the HttpSession and read that from the servlet and make the decisions accordingly.

I want to read data from URL (http://84.100.130.82:8000/;stream.nsv). But can not do it. Because when try to call function openDataInputStream() shows this error: java.io.IOException: response does not start with HTTP it starts with: ICY. How I can fix this bug?
HttpConnection c = null;
InputStream is = null;
OutputStream os = null;
StringBuffer b = new StringBuffer();
String response,

c = (HttpConnection)Connector.open(“http://84.100.130.82:8000/;stream.nsv”);
os = c.openOutputStream();
os.flush();

int ch;
// receive output
while ((ch = is.read()) != -1)
b.append((char) ch);
response = b.toString();Regards, Ramunas

Calling Webservice from Netweaver Portal to SAP XMII 12.0 using SSO

Hello,
we have a Netweaver 2004s based Portal and a Netweaver-based SAP XMII (v12.0) System providing Webservices.
What we try to do is to call a webservice out of the Portal EAR Application using SSO.
SSO-Konfiguration between Portal and XMII is done and works fine. I tested this using an URL-iView, which calls a https-URL on XMII and SSO-Authentification is done in the background.
Now I want to call a Webservice using SSO.
Without SSO (prodiving UID/PW), the webservice-call works fine.
In order to use SSO with Webservice, I created a "Deployable Webservice Proxy" with "HTTP-Authentication" and "use SAP Logon Ticket" turned on.
Then I remove Login/Password from my SOAP-Request and unfortunately it doesn't work.
What do I have to consider in addition to the topics above?
Can you provide any useful links with tutorials, hints, documentation, ...?
Thanks in advance
Andreas

> Can you please list all the options that we have in order to implement SSO for EP and SAP GUI?

> I could not find any info in regards to the advantages and disadvantages of each SSO solution. Do you have any links that gives this information?
If you search the forum here for the terms you have used, then you will find many of them and interesting discussions about advantages and disadvantages from different views. I think that in 1 or 2 hours you will be a guru
> I am thinking more of using Kerberos authentication for SAP GUI and using OpenSSO (Sun's product)solution for EP 7.0.
>
> Do you know what SSO technologies are other companies implementing these days?
I only know which solutions I have been involved in doing the security evaluations for and implementation support.
I don't want to do any direct or indirect comparative advertizing here, but only wanted to point out to you that there is plenty of information if you use the search. What you need to understand is that other that SAP proprietary mechanisms and newer standards based initiatives (search for 'SAML'), this is often a 3rd party vendor question (and resulting discussion...).
If you find a solution and want to specifically discuss it here, then this can most of the time be done in a civilized way...

Hi,
Add this line inside your run() method, right before your call to repaint():
if (image != null) {image.flush();}Hope this helps,
Kurt.
