Report Engine SDK - Rbean usage in standalone java application

Post Author: Berndb
CA Forum: JAVA
In BOXI the rebean sdk is available in the Report Engine SDK.
I remember that in the 6.5 world one could use RBEAN interface in a standalone java application.
Is this still possible in BOXI R2?
If yes can you supply a sample classpath which shows all libraries that needs to be assigned.
Thanks in advance.

Ted's right, but for fun, take what you need from:
<installation drive>:\Program Files\Business Objects\Tomcat\webapps\businessobjects\enterprise115\desktoplaunch\WEB-INF\lib
and de-reference what's not needed when your project's done, but be careful.
I've actually done some standalone Swing-based webi report renderers using https://xhtmlrenderer.dev.java.net/ + docHTMLView.getStringpart + TagSoup

Is it possible to use the JAVA Report Engine SDK to modify DESKI reports?

Post Author: Nadine
CA Forum: JAVA
Hi, is it possible to add a complex filter to a DESKI report using the JAVA report engine sdk?
In the developer tutorials for this API, I've only found references to WEBI in terms of modifying reports, though it seems to be possible to view DESKI reports with this sdk.
I am a bit confused in terms of the scope of this API and how I would use it in regard to DESKI.
Many thanks for any suggestions!

Current (XI R2) version of ReportEngine API only supports refreshing/viewing functionality for Desktop Intelligence documents. Document modification/creation is only supported with Web Intelligence documents. Queries aren't modifiable for Deski using ReportEngine API - you can only do so using Desktop Intelligence Reporter SDK, which is COM based.Sincerely,Ted Ueda

Report Engine SDK Performance

What are the recommended settings for businessobjects xI (version 11.5)
Are there any tips to improve performance and reliability of the Report Engine SDK?
It is very slow. We are using a Java client to interact with the dswsbobje libraries.
Calls to " reportEngine.getDocumentInformation" are not consistently working even from the same program.
We supply the prompt info parameters to generate the report.
It works for the first 3 times, then fails a couple of times, and then works again.
Sometimes a report load in 3 seconds, and other times it loads in 30 seconds or not at all.

Why not open a case with SAP Support?

Report Engine SDK sample code questions

Hello,
I've been able to view a boxi report in an iframe via the Enterprise SDK by modifying the sample code in the HowToViewWebiReports_VB example.
I'm not totally happy with the way that's working, so I'm looking at using the Report Engine SDK, although I understand it's performance and scalability isn't quite as good as the Enterprise SDK.
I'm a VB.NET guy, not a C# guy, and I'm not clear on how the wssdk_net2.0_portal_sample_12.0_en example is supposed to work.
I don't have one and my CMS server is running Tomcat, not IIS so there's not going to be an ASP.NET web service running there.
In the dsws.config for the wssdk_net2.0_portal_sample_12.0_en example I put the name of the CMS server, but it's looking for a web service at http://cmsservername:8080/dswsbobje/services/Session, but I get a 404 when i try to hit that.
I'm not familiar with Tomcat, but in searching around on the server, I see a dswsbobje directory under the webapps in my Tomcat installation, but I don't see a services or a Session folder underneath that. In the dswsbobje folder I see the following folders:
BOAR-INF
META-INF
WEB-INF
xsd
Is there something else that needs to be installed on the Tomcat server to get the web service running?
-Eric

It looks like I have something there. When I launch launch http://servername:8080/dswsbobje, I see:
Apache-AXIS
Hello! Welcome to Apache-Axis.
What do you want to do today?

Validating Axis
If the "happyaxis" validation page displays an exception instead of a status page, the likely cause is that you have multiple XML parsers in your classpath. Clean up your classpath by eliminating extraneous parsers.

Report Engine SDK: CommunicationException when accessing IReportEngine members

Hello,
I have installed BOXI 3.1 SP3, including the .NET SDK, and I am trying to use the Report Engine SDK part to navigate through a WebIntelligence document (analyse its structure, etc.), via a Console App.
I built my console app targeting .NET framework 3.5, and compiled it in 32 bits mode (x86 platform). I can access the standard SDK without any problem and log in to the CMS then retrieve any InfoObject instances from my enterprise server.
My problem occurs when I try to access my BusinessObjects.ReportEngine.IReportEngine instance's members. Sample lines of code:
SessionMgr sessionManager = new SessionMgr();
EnterpriseSession session = sessionManager.Logon(login, password, cmsName, authType);
InfoStore infoStore = (InfoStore)session.GetService("InfoStore");
UserInfo userInfos = session.UserInfo;
string logonToken = session.LogonTokenMgr.CreateWCAToken("", 1, -1);
ReportEngines reportEngines = new ReportEngines(logonToken);
IReportEngine reportEngine = (IReportEngine)reportEngines.getService(ReportEngineType.WI_ReportEngine);
bool test = reportEngine.IsReady; // or any other member of reportEngine, like reportEngine.OpenDocument(...)
An exception of type 'BusinessObjects.ReportEngine.CommunicationException' occured.
Message:
The Web Intelligence server could not be reached. Contact your Business Objects administrator. (Error: RWI 00236), Session Init Failure,

What do you suggest?

Hi,
Enterprise / ReportEngine SDK is not supported / tested / compatible with desktop / console apps.
Could you try the same logic with a web services sdk, as WebServices SDk is the only SDK which could be used to develop thick client apps.

BO edge 3.1 howto Report Engine SDK sample

Hello,
I'm trying to install any report engine SDK sample on a BO Edge 3.1 installation.
The webserver is WACS (Web Application Container Server).
I don't know how to set up a web application that uses the SDK, and I cannot find any useful documentation.
Has anyone done this?

Hello,
Crystal and Xcelsius are client tools so you don't need to install them on the server.
It might be useful to install them on it when you are troubleshooting issues which might be related to network (firewall, load balancer,...) but otherwise you can keep them on the clients machine.
The client machines connect to the server by specifying the server details (CMS name and valid user account) when you try to export the reports to the repository.

Passing dynamic prompt value using Report Engine SDK

Hello Experts,
I have created a webi report which contains prompt. Using SDK, I would like to catch the value of prompt which is selected by a user at runtime.
e.g. If prompt contains values year, quarter, month, etc and user has selected value of u2018Quarteru2019 at run time, then I would like to catch that value using Report Engine SDK.
I tried to implement prompt.getCurrentValues(). However that is not working.
Can someone please help me to figure out the way to catch this dynamic prompt value using Report Engine SDK?
Thanks,
John

Where is the prompt values being set, and where are you trying to catch it?

How to get Portal user from a standalone Java application

Hi,
I have a standalone Java application from where I need to fetch the Portal User Information like userid and email id.
I am using the below line of code
iUser = UMFactory.getUserFactory().getUserByLogonID("e017939");
I have included the jar file com.sap.security.api , But it was giving me the below exception
java.lang.NoClassDefFoundError: com/sap/tc/logging/Location

     at com.am.ScheduleEmails.main(ScheduleEmails.java:89)
and I am getting a pop Up message from the Java Virtual Machine Launcher, saying a Fatal Exception has occured and the Program will exit.
Then I went throught he SDN threads and they asked me to include the
logging.jar and com.sap.security.perm.api .
I Included them, then also, it is giving me Exception
java.lang.NoClassDefFoundError: com/sap/engine/lib/logging/LoggingHelper
     at com.sap.security.api.UMFactory.<clinit>(UMFactory.java:56)
     at com.am.FetchKMData.main(FetchKMData.java:30)
Exception in thread "main"
and I am getting a pop Up message from the Java Virtual Machine Launcher, saying a Fatal Exception has occured and the Program will exit.
Kindly let me know if it is possible to access the User info using UMFactory in a standalone Java application. If yes kindly let me know where i am going wrong.
Regards,
Shilpa B.V

Hi Shilpa,
1. Check that you have added com.sap.security.api within the Your Project>Libraries folder (under navigation tab) and also added jars in the build path of the Your Project under project>properties>Build Path.
2. In case you have a DC instead of Web Dynpro Project then you have to add the com.sap.security.api under Your DC>Used DCs and have compile time and runtime dependency added.
Here java.lang.NoClassDefFoundError is caused basically due to only build time dependency added and reference to the jar missing at runtime. Rest the code to retrieve the current user id using UME API and getUserByLogOnID("....") method with/without portal environment would not be an issue at all.

Reading a XML file in a standalone java application

Hi,
What are my options if I have a standalone java application running outside any app. server and I need to read an XML file, probably read some of the attributes in the file...? Please explain clearly as I'm new to this. Appreciate your help.
Thanks,
Mahdad

nope you don't need a DTD
you have to write your Java code in a way that doesn't rely too much on the structure:
- avoid getFirstChild().getFirstChild()... because you know that this element is first grandson of that element)
- prefer using getElementByTagName() or some XPath() API
but if the XML completely changes, well, yeah, you have to do some programmation: better think well your document structure in the beginning.

What should be done in certmap.conf for 2-way SSL support from a standalone Java application to an SSL enabled LDAP Server

To support certficate based client authentication using 2-way SSL from a standalone java application which uses JNDI and JSSE1.0.2 to connect to an SSL enabled LDAP Server how do we configure the certmap.conf?Is there any additional setup required at the LDAP Server side apart from enablinf SSL with the option"Required Client Authentication" enabled.The 2 way SSL handshake goes through but the access log file (After configuring the certmap.conf for the issuer DN of the client certficate etc..)shows SSL failed to LDAP DN?But inspite of this access log error the Java client does get an SSL Connection object with which it is able to connect to the LDAP.IS the certmap.conf file being looked up by the LDAP Server at all?

have you out.flush() and out.close() before you call connection.getInputStream()?

Can we call a webservice using standalone java application ?

Hi friends,
               Can we call configurd webservice in xi , using standalone java application by just giving url of webservice ?
              OR
              Only by means of WEBDynapro we can call ?
                Can you please tell me the answer for this .
Regards .,
V.Rangarajan

HI Ranga Rajan
well, If at all if you have webservice...you can import that werbserivce as External definition in to IR.
How to import:
1) Go to IR and and move to your requied component and there you can see the option called imported objects...select on imported objects where you can give the name and you can select the webservices which you want to use it.
2) Hope you are aware of that a werbservice will have the request and response.
3) Create the mapping program accroding to your requirement.
Go through blogs of Bhavesh and Naveen which talks about calling webservice in a specific condition:
Webservice Calls From a User Defined Function - /people/bhavesh.kantilal/blog/2006/11/20/webservice-calls-from-a-user-defined-function
Consuming/Calling webservices from DataBases - /people/sap.user72/blog/2005/10/20/consumingcalling-webservices-from-databases

Accessing JNDI from Standalone JAVA application

Hi,
I want to access the JNDI tree from my
standalone java application. (ie I have
one weblogic server contains all my ejbs and client - swing - application which accesses that. )
Here I don't want to ship weblogic.jar
file to the client with swing application
because it is of ~ 20 MP.
Any other way to specify the INITIAL_CONTEXT_FATORY class.
My code is
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
env.put(Context.PROVIDER_URL, DTEConfig.PROVIDER_URL);
But since I don't want to give the
weblogic.jar bundle to my client, how he
could manage this with out weblogic.jndi.WLInitialContextFactory
with him to get the initialContext ?
-Rajan Kumar

You can strip out the jndi related classes from the weblogic.jar which can be distributed
to the client installation. I don't think you will be violating any bea licensing
policies with this.

How to pack a standalone Java application

Hi, all. I have a stand alone Java application which includs some classes and some properties files. Meanwhile, I'm using some libraries(in jar files) from 3rd party as library extension.
When I developed my application in the IDE, I can run it from the IDE and it works fine.
Now I want to run it out of the IDE, it always complains that is can't find the 3rd party classes. I have tried to modify the classpath to include the extension libraries but it goes no avail. What might be the problem?
And normally, how will you pack the application to submit it to the end-users? How do you include the libraries from 3rd party without end-users' awareness?
Thanks a lot!

Put it in a jar, and use the classpath-setting in the jar manifest file.
Or extract the 3rdparty libraries, and put everything in a big jar.
Or provide a .bat-file and a shellscript that sets classpath temporarily.
