Start a BO report from within a web-application.

Hi,
An enuser want to start a BO report from within a web-application.
The BO report ideally should not prompt for a login. The fact that we are using BO for reporting purposes should be transparent to the end users. The report should produce its output directly in Excel (pdf?) format. In WebI i can do a 'Save As' to obtain this, but it should go automatically so that the end users get their response directly in Excel
the report should be parametrized. These parameters will be added to the URL by the calling application.
To do a basic test of the Opendocument.jsp i created a number of test reports in WEBI, and i use the following URLs to execute them directly
http://s-olaf-vtst150:8080/OpenDocument/opendoc/openDocument.jsp?&sPath=[My reports]&sDocName=tmsd1&sType=rep&sRefresh=Y
http://s-olaf-vtst150:8080/OpenDocument/opendoc/openDocument.jsp?&sPath=[My reports]&sDocName=Yearselection&sType=rep&sRefresh=Y&lsSYear:=2002
So this covers points 1 & 4
What are the options for points 2 & 3?
Kind regards,
Johan

The BO XI 3.1 environment works quite well now.
Two more questions:
1. When a user being member of the Readers group, still sees the Edit button in Webapplication - Infoview. Is it possible to hide or disable that Edit button ?
2. Is it possible to make a user only seeing a part of the data in the universe ? When a query is run with a parameter, the user ses the parameter in the left column ... but in that way a normal user can change the value of that parameter giving him the possibility to see things he should not see. Making a separate query per user is overkill and too much work to do. Is BO XI 3.1 able to offer this possibility and how ?
Rgds,
Johan

How to create reports from my existing web application on Java/J2EE with Oracle Client 10g as the backend?? Help sought for

Our company has developed an Web Application and we are also looking out for the development of reports using Business Objects Exterprise XI Release 2 and for this purporse I do require some help from the forum who can literally show me how to get on and working on creating the reports.

Thats why I thought I should make the following chain in the keystore, possibly in this order.
1. My private key (simply generated in the server)
2. Import Root certificates from NS
3. Import Trusted certificate issued by NS
Then when I sign with my private key surely an association will be formed to the trusted authority certificate. The problem I'm having is when I first made my private key I used openSSL as it was only intended for HTTPS. Now I need to create a keystore so I can use jarsigner to sign the jar file, and I can't see how to create a keystore using my existing private key. Surely if I created a new key and self sign, then import the trusted certificate the association will fail, as the private key will not be the same 1 that I used to make the CSR when applying for the trusted certificate.

Calling a webservice from within Bex Web Application Designer

Hi
I have a web-template built with BEx web application designer which also contains textboxes. This text should be stored by calling a webservice (standard BI-documents are not an option).
Can anyone tell me how I could call a webservice from within the BEx web template to store the text contained in the textbox? The webservice-call should include some of the filter-varialbes of the web application.
Is this only possible by the use of a JavaScript WebItem? If so - does anyone have an example of such a JavaScript.
Thanks a lot in advance.
Kind regards.
Christoph

Thanks for your response. The BSP page would work out fine if I only needed to save the data.
But the next time I call the webtemplate, the textarea should be filled by another webservice call with the stored text (so the text can be modified und saved again). This will not be possible by calling a BSP page.
Do yoiu have any suggestions how to integrate the text (return value from the webservice call) into the textbox in the webtemplate?
Kind regards.
Christoph

Accessing KM content from within a web application

We are trying to migrate an application from a BEA webServer onto the webAS. The application relies heavily on the BEA content management system (CMS), this is to be replaced by the KM. We cannot rebuild the application using iViews etc as we have to retain the current look and feel, and hence we will have to call the KM content from the jsp code within the application. Does anyone know if this is possible and can give us an idea of what API's we call...(if the APIs exist and if this is the correct approach).
Many thanks

]> call the KM content from the jsp code
]That sounds not very well designed...
BEA have a content tag library for extracting content from the CMS within a JSP page. I think this is what James may be referring to.
Does the KM have equivalent taglibs? If so, can these be configured to access the KM running on a different J2EE instance (specifically one running on another machine).
Going to browse the API docs anyway, but if you have a short answer to this, please post.

Is there a way to control Adobe PDF plugin from within a Web Application? For Example, Can we highlight text in the PDF/A document programatically?

Hi,
I am trying to open a PDF document in browser using Adobe PDF plug-in for IE 9. The plugin version is 10.x
I need to highlight certain text in the PDF document ( which is searchable) programmatically. For example, when a user selects certain text on the web-page, we want to automatically highlight that in the PDF document.

I don't think this is a question one can answer by simply downloading the SDK. And even if one reads all the documentation (it rarely happens for obvious reasons), it is not easy to reach an answer because its explanation is not trivial at all.
In my own opinion, this is right the type of question to be put and (hopefully) answered in a Forum.
Now, I am not sure about the correct answer but I will give one hint.
If I am not wrong, the Internet Explorer, IE, PDF viewer by Adobe is actually a .dll file which is put under IE once Adobe Reader is installed. A custom plug-in for Reader or Acrobat is also a .dll file (Windows) but its extension is .api and it needs to be copied under Reader or Acrobat (or both). Therefore, I don't see how we can merge the IE viewer .dll with a custom plug-in .api. Though maybe technically possible, I don't think it is something we can do.
If above reasoning is correct, the answer to the question is No.

Can't print a report from within web application

I can run the report within Eclipse and it displays fine. When I click the export button a modal window comes up and all works as expeced. If I click the print button then a modal box comes up but it is blank except for a little white square up in the top left corner.When I view the html source in the browser, the displayPrintDialog function makes reference to active X print control.prm.codebase = "../ActiveXControls/PrintControl.cab";but I don't have that within my web application. Is there something that I need to install on this machine to get printing to work?Any help would be greatly appreciated.Marty Jones 

Unfortunately the ActiveX print control was not validated with the CR4E version of the Java Reporting Component. Therefore users must implement the prininting via the PDF print option. The print option is determined by the printMode property of the viewer. The default should be PDF but if you want to ensure that it always uses PDF you can set the following code using our API: crystalReportPageViewer.setPrintMode(CrPrintMode.PDF);If you are using the Tag Libraries you should set the property printMode equal to PDF.Hopefully, in a future release we can look at adding in a "pure" print option again.

How To Start Forms and Reports From Start Command

Hi All,
How to start Oracle Forms and Reports in Oracle8i My OS is Windows 2000.Please tell the procedure to get into forms and reports.
Otherwise we have to install other software for Forms and Reports.
Thanks
Sujan

Sujan,
what does the database have to do with starting Forms and Reports ? If you are on Wondows2000 then navigate to the \bin directory if the Oracle Home you installed Oracle9iDS to. Type ifbld90 for Forms and rwbuilder for Reports design environment.
If your ability to start Forms and Reports from the command line is your only exit criteria in evaluating software for a project , how far will you go with it?

Open client socket from within a Web Service

Hello,
I need to open a client TCP/IP socket from within a Web Service-type WebLogic
Workshop app. When I try to read from the socket, the socket read operation hangs.
When I use the same code in a J2SE Java app on the same machine using Eclipse
everything works fine. It also works fine from within WebLogic, if I use a "URL"
object instead of a "Socket" object. (However, I cannot use this type of connection.)
Can anyone tell me how to work with raw TCP/IP sockets in this situation?

Hi Udi,
I have tested my code from within a Servlet and it works fine.
The Servlet and the Web Service both call the same simple JAVA class. This class wants to access a DB, and therefor, I am using the Data Source.
When the Servlet calls the class, everything works fine. But when I use the Web Service to call this class, I get the Exception "No attributes are implemented".
I hope this information helps you understanding my problem?
Thank you very much for your help.
Kind regards,
Nadine

I am trying to call a Portal Service from within a Web Dynpro development component without sucess.
Can anyone give me some hints on the necessary steps in order to accomplish this task?
Thanks
Diz

Hi Diz,
I tried doing the same thing by following the steps as mentioned by you. Just to re iterate,
1. Created a DC "Portal Application Standalone" project by the name myservice.
2. Created a portal service inside myservice by the ame AmitsService.
3. Exposed IAmitsService.class in the public part.
4 Build and deployed the DC on server and tested it through an abstract portal component and it worked FINE !!
Now..
5. Created anoter DC of type WebDynPro
6. Added SAP_JTECHS -> epbc.prtapi._api as a "Used DC" with dependency build time and runtime
7. Specified the sharing reference in the properties as PORTAL:sap.com/myservice
8. Tried to reference the service using the following code..
IAmitsService portalservice=(IAmitsService)WDPortalUtils.getServiceReference(IAmitsService.KEY);
9.Build and deployed the DC.
10. When I run the application I am getting the following error
Processing HTTP request to servlet [dispatcher] finished with error.
The error is: com.sap.engine.frame.core.load.SAPNoClassDefFoundError: com/sapportals/portal/prt/service/IService

Report 9i performance on Web Application

I've developed a report using Report Builder 9i. The report run smoothly in the builder, but it takes a very very long time to execute when called from web application.
I've tried to execute the report's SQL statement in SQLPlus to see whether there is performance problem , but strangely the SQL executed effectively in SQLPlus.
Can anyone tell me how to improve the report performance on my Web application?

How do you execute the report from the web application?
Are you generating the report output to HTML / HTMLCSS formats? HTMLCSS report output takes longer time to load into browser.
Try to use "Run to web" option in Reports builder and check if it takes more time.
You can also refer to the following document "Tuning Oracle9i Reports" from http://otn.oracle.com/products/reports/htdocs/getstart/whitepapers/cb_tuning8.pdf

Call a JSF application from a Standar Web application (JSP)

Hi all,
We have 2 aplication, one is JSF and the other one is standar web jsp.
We want to invoke from the standard web application to the JSF application and pass param from the jsp to the *.jsf page.
how can I do that?
Thanks.

You can open a jsf page from any other application.
<form action="http://hostip:port/app/MyPage.jsf?key1=value1&key1=value1">
as we do in any other jsp page.
Now in JSF application, in MyPage.jsf write a scriptlet to get the parameters and from there you can use these params.
You can get a managed Bean reference in your jsp page. Here is the code for that.(ResultsInExcelBean is my managed bean.)
FacesContext fc = FacesContext.getCurrentInstance();
ResultsInExcelBean resultsInExcelBean = (ResultsInExcelBean)fc.getApplication().createValueBinding("#{ResultsInExcelBean}").getValue(fc);
Hope this helps you.

Calling OWF from customer build web application

All, All the example that I've read from OWF documentation is assuming that you builder the workflow from OWF Builder and manage it thru OWF manager, monitor is thru OWF Monitor. I'm wondering if it is possible to monitor the workflow and manage the workflow from customer build web application. Since we don't want our users have to login several times and use different URLs to get into the customer build application, then manage the workflow and monitor it via different urls. Anybody has experience doing all from one application can provide any insight would be greatly appreciated.
dsl

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,
Regards,
Luiz

Calling a report from form using web.show_document

Hi,
Used the method as below, But , error reprot not found,
Could anybody tell me how to get the server name from ny local machine as in the example servername ' Repsrv '
/* WHEN-BUTTON-PRESSED */
DECLARE
vc_url varchar2(100);
BEGIN
vc_url:=‘http://<hostname><port>/reports/rwservlet?server='
||
‘Repsrv&report=reptest.rdf&desformat=htmlcss&destype=cache ’
||
'&userid=user/pw@database&p_deptno='||:dept.deptno||'&paramform
=no’;
WEB.SHOW_DOCUMENT(vc_url,’_blank’);
END;
Thanks

If you are attempting to print a report from a when-button-pressed trigger from within a form, you do not have to explicitly specify the server (hostname) nor the port. You can just use what I've found referred to as a virtual path to the server as I have done here:
parm_string := '/reports/rwservlet?config=my_config&report=report_name'
 ||'&desformat=pdf&destype=cache'
 ||'&paramform=no&printjob=no'
 ||'&p_my_user_param1='||v_my_param1
 ||'&p_my_user_param2='||v_my_param2;
web.show_document(parm_string,'_blank');
You can specify a userid/password@connectstring within a named congifuration section of your formsweb.cfg file if necessary, e.g. my_config.
Hope this helps.

Can u call a BIP Report from within Oracle Forms?

Hi,
We want to use BIP as a reports solution for a Forms 10g Application. Currently we use oracle Reports. I would be very grateful if anybody can show us how to do the following as I could not find it in any documentation. Of course, I get the feeling that these cannot be done, but I want to double-check.
(1.) How to call a BIP report with a input parameters from within an Oracle 10g Menu? i.e. when the user clicks on the menu item, BIP should be started and it should run the report within the BIP.
-- So we also need a way to pass parameters to the BIP
-- Also BIP has a different username/password also
Is this possible or NOT POSSIBLE( i.e. U have to ask the user to login to BIP and then run the report)?
Thanks & Regards,
CS

Hi,
Have a look in this document to get an idea how to do:
