Handle HttpRequest and Responce in WSRP Portlets

Hi all,
I have deployed a fusion ADF application as a WSRP portlet on webcenter portal.
In my portlet application code i want to perform some file handling operations(like open a file in browser) using ADF table components.
I had used Http sevlet request and responce but portlet throws a following exception.
java.lang.ClassCastException: org.apache.myfaces.trinidadinternal.config.dispatch.DispatchResourceResponse cannot be cast to javax.servlet.http.HttpServletResponse
Any one has some idea about how to handle http request and responce in WSRP portlets.

Hi
Portlets don't use HttpServletRequest & HttpServletResponse.
Use instead of them: PortletRequest & PortletResponse
Regards.

Passing parameter to a portal page that display a WSRP portlet ?

I have created, deployed and regisered a WSRP portlet to Portal 10.1.4. I also create a portal page used to render this portlet. I would like to pass in a parameter xx (thru the HTTPRequest) when calling this page and have it visible to the portlet inside the page. Something like http://host:port/portal/page/portal/myPortlets/portletA?xx=123 where
"http://host:port/portal/page/portal/myPortlets/portletA" represented my portal page and "xx=123" is what I want my page to see.
Is it even possible/support by Portal 10.1.4 ?
Thanks.

Handling large files in scope of WSRP portlets

Hi there,
just wanted to ask if there are any best practices in respect to handling large file upload/download when using WSRP portlets (apart from by-passing WebCenter all-together for these use-cases, that is). We continue to get OutOfMemoryErrors and TimeoutExceptions as soon as the file being transfered becomes larger than a few hundred megabytes. The portlet is happily streaming the file as part of its javax.portlet.ResourceServingPortlet.serveResource(ResourceRequest, ResourceResponse) implementation, so the problem must somehow lie within WebCenter itself.
Thanks in advance,
Chris

What is the difference between JSR 168 portlets and WSRP portlets?

What is the difference between JSR 168 portlets and WSRP portlets?

Here is the difference between JSR168 and WSRP:
The WSRP specification does not make any statements as to implemention. Java's portlet specification, JSR 168, and WSRP are not competing technologies. JSR 168 may be used to define a portlet, and WSRP may be used to define a portlet's operations to remote containers. JSR 168 portlets and WSRP may be used together to define a portlet and to provide remote operations. Similarly, .NET portlets may be created for use with WSRP. Interoperability between JSR 168 and .NET WSRP implementations has been demonstrated

WSRP Portlet and Default Minimized Property

Good Morning, i'm working with Oracle WLP 10.3.4 and i have a problem with Default Minimized Property for a Remote Portlet.
I set this property to true for a portlet and if i run it in a local environment this portlet show, correctly, itself minimized.
When i use the same portlet like "remote portlet" -configuring the producer from the administration console- it is not minimized.
There is no way, for a remote portlet, to show itself minimized by default?
Thanks
Alessio

Hello,
Many thanks for this quick feedback. It does work.
We were configuring our producers & portlets directly through WLP admin console : we were expecting WLP to recognize automatically this "defaultMinimized" flag from the remote portlet and configure the proxy portlet with this flag set as same. It is indeed not the case, so we did as follows :
- Create proxy portlet on our consummer application, with defaultMinimized=true
- Add this portlet to our .portal file
Thanks again.

Consume Wsrp Portlet Error

Hi,I am new to webcenter, and my situation is : I develop a very simple bounded task flow(using page fragement) which just shows the employees list and emplee detail info views, nothing special and it works well in the jsf page as region, then I create the portlet with the task flow and register the wsrp producer in the webcenter space (these steps also go well). However when I drop the portlet into the page , the error displays as below. And then I make the jsf page including the task flow as region to the portlet, when it is dragged into the space page , the portlet content reload and refresh again and again .
My JDeveloper version is:11.1.1.4.0_GENERIC_101227.1736.5923

Hi,
How did you create your portlet?
The default way, how to create a portlet from the ADF project in JDev is the right click on the JSPX page or tasklfow you want to portletize and choose the item "Create Portlet Entry ..." from the menu. The Jdev automatically wraps your ADF project with portlet stuff.

After using a TCP monitor, I found out that the WSRP was not being contacted at all by the portal upon adding the portlet to the page. In my case, the WSRP was running on port 7778. However, when I changed OC4J listener port to 80 and redeployed all worked well. At this point I am trying to determine if this is a firewall issue or something else.

OutOfMemoryException in WSRP portlet in 10.1.4

We are facing the OutOfMemory exception when recieving a PDF file (10KB) as byte stream from the AXIS Webservice client, inside the WSRP portlet.
Portlet log simply states OutOfMemory and no stacktrace is available.
Surprisingly, if the webservice returns String of the same PDF instead of the byte array, it works. Any idea how overcome the OutOfMemory without changing the webservice?
Thank you

WSRP Portlet open new window

Hello allm
I have three wsrp portlets on a page, (Applications navigator, favourites, worklist) and when I click them I get the correct link so they work just fine. MY problem is, clicking any link in a portlet will open that link in the current window, thus loosing the portlet window. Does anyone know how I can force this to open in a new window? It sounds like a simple task but have not been able to find that conig setting just yet..
Thanks in advance.
Grummy

For anyone else that stumbles upon this issue, the resolution is as follows:
Edit the region where the portlet resides
go to Attributes
move 'Link - Display Name' to the 'Displayed Attributes'
Back on the main edit page, click actions on the portlet, edit portlet, and then select display as Link That Displays Portlet In New Browser Window, done.

Wsrp portlet discovery

Hello!
I have just installed websynergy-gfv2-linux and started playing with it. I am interested in the WSRP support of the product. Right now, I am trying to do a simple test: I want to use the WSRP portlet discovery mechanism to search for a portlet in a UDDI registry, and then start a WSRP consumer that consumes that remote portlet. The question is: is this operation supported through the admin interface of websynergy? I ask because when I get to the WSRP Consumer Admin interface, I get only the oprion to specify the URL of the producer to which the consumer must connect.
Thanks,
Florin.

Registry support i.e both publishing and discovering is not there in websynergy. There is no plan right now to support it, older portal version esp 6.x had ebxml registry support but this was later dropped.
However if registry server provides users the option to publish and discover artifacts, you can use it. Its just like publishing and discovering any other artifact on a registry server.

WSRP Portlet deployment

I have a simple WSRP portlet, which I developed in JDev as an ADF app using a Business Object bound to an ADF Form, via JDBC to a remote Oracle 11g database, and portletized using the Portlet Bridge/Wizard.
Everything works fin locally on the Integrated WL server, but when I deploy it to my Weblogic Managed Server, it tries to run, but just hangs perpetually at the twirling O initialization progress indicator.
I've isolated the problem to being related somehow to the database connection, by creating an identical app with the same adf form elements, sans the database binding, and it works fine.
I've double checked that the jdbc connection, which I have depolyed to the same wls target that I'm deploying the portlet to, works and is using the same driver, and that the jndi names match, but am at a loss now as to where else to look to find this apparent disconnect.
Would love to hear from anyone that may have experienced this and found the cause, or anyone who might have any suggestions as to further troubleshooting steps I could take.
Thanks!

Found the solution on Metalink (Note 437789.1) by editing the existing v1 wsdl and creating a dummy one in my deployment file.

WSRP portlets - consumer-side backing files

I'm trying to find a way to send the consumer-side portlet instance label and the desktop definition label into my WSRP portlets. The BEA WSRP documentation indicates that using a backing file is the way to do this. The only problem is that even though creating a backing file and extracting the two strings is straightforward, it isn't clear how to go about communicating the information from the backing file to the WSRP portlets, since the session and request spaces are independent. I could use some recommendations. Thanks in advance.

There is limited support for this in 10.3, in 10.3.2 there are some javascript libraries to help you add parameters to URL.
In 10.3 your best bet is as follows:
Do NOT modify the URL, instead do a POST to your actionUrl and pass in the parameter in the POST body. You, will also need to do use a PortletXMLHttpRequest to avoid getting the entire page returned.
Good luck,
Nate

Click on link in one portlet and open in another portlet

how do you click on link in one portlet and open in another portlet?

Hrmm... This is a IBM Question..
Officially this is a meaningless buzzword promoted by IBM. Portals are some sort of Servlet but IBM incapable of explaining how they differ from ordinary Servlets. Some speculate they are used to present a webpage with many services on it such as a search engine, and news that come from diverse sources. The user is able to dynamically configure the contents and layout of the page much like Netscape home pages
I don't understand what yhour asking..
I am assuming you want to call another servlet (portlet)? That would be absurd to do .. You let the HTTP request and XML file to deal with the response of the portlet

Handling Units and BADI_HU_AUTOPACK

We are setting up handling units(HU's) to be created at the time of Transfer Order(TO) creation. We have implemented the badi BADI_HU_AUTOPACK. What I am looking for is the way to link the handling unit number with the line items on the TO so that when the user goes to confirm the transfer order the HU's and the line items are aligned as desired. In the CT_ITEMS parameter I can see the handling units and the TO item data, but the hadling unit number has not yet been created. I would appreciate any input on this issue.

Those fields are filled. The HU is field EXIDV below, and the $0000000001 is like a placeholder, since the HU number has not yet been generated. My assumption was that this number to be created would be linked with the TO Item 000001. This is not the case when viewing the TO.
VENUM     C     10
EXIDV     C     20      $0000000001
VELIN     C     1      1
