Problem with a jar file rebean.wi when updating 3.1 to 4.1

[Former Member]

I'm updating our java application using the SDK and I met an issue with the jar rebean.wi.jar.

In our jar from 3.1, we have the class com.businessobjects.rebean.wi.occa.WebiReportEngineFactory

But in the jar I get from the installation folder of BO 4.1, we do not have that class anymore.

Can you help me?

Thanks in advance !

I take a look to the pdf file and it seems I do not find any reference to the class "com.businessobjects.rebean.wi.occa.WebiReportEngineFactory" in it :s

Thanks in advance

Hi,

Are you getting this exception, when you are trying to instantiate the report engine service?

Can you please attach the piece of code you are using which throws the exception.

Also try to update the jar files of your application to that of BI 4.1. Remove any referrences from XI 3.1 from your classpath and re-run the application.

Thanks,

Prithvi

Yes, it's happenning when we instantiate the ReportEngines Object.

Here the piece of code concerned :

...

try {

  logger.debug("create report engines instance");

  this.reportEngines = (ReportEngines) connection.getEnterpriseSession().getService("ReportEngines");

  logger.debug("report engines instance set");

} catch (SDKException e) {

...

For the cleaning of the JAR's files, I'll re-check it.

So, I forget one old jar file (another rebean.XXXX.jar) and the problem does not occur now.

But I'm locked on another problem when I try to export the report...

the line where the problem appears :

Report report = null;

...

[Lines where report is instantiate properly and in anycase]

...

report.setPaginationMode(PaginationMode.Listing);

At that point, everything stop and the only stacktrace I have is :

com.businessobjects.sdk.core.CoreException

Do I miss a specific jar file for the export?

This method should work.

For testing, remove all the jars BO from your applications classpath and include all the jars from BI 4.0 installation. No jars from XI 3.1 should be there and test the same.

There is no official list of jars for report engine sdks in BI 4.0 because of the deprecations, so the above test might give us more depth regarding the error.

Thanks,

Do you mean all the jars files from "external" folders too?

[Former Member · Accepted solution]

Hi Jerome,

Yes, for testing you need to add all the jar files from the following two locations:

C:\Program Files (x86)\SAP Business Objects\SAP BusinessObjects Enterprise XI 4.0\java\lib

C:\Program Files (x86)\SAP Business Objects\SAP BusinessObjects Enterprise XI 4.0\java\lib\external

As mentioned, please remove all old references of BO XI 3.1 jar files from your classpath and add the above specified jars

Hi,

I add all the jar's and proceed to remove all the un-necessary jar (I can't load so much jar in our project).

The project is working on my local computer

Thank you !

Hi,

We do get the same exception when we run our existing code (developed for BO XI 3) with BO XI 4 libraries. When we add all the libraries it is working fine. However we cannot package all the jars with our application due to the size. Kindly please share the jars you added to resolve this issue.

We call the getService method of ReportEngines class passing in the WI_REPORT_ENGINE in instantiate ReportEngine class. But it is throwing the exception

java.lang.ClassNotFoundException: com.businessobjects.rebean.wi.occa.WebiReportEngineFactory

Thank you !

Hi Jerome,

There are lot of classes and methods that have been deprecated in BI 4.1 Report Engine API's and hence you were unable to find the above mentioned class.

For a complete list of deprecated methods, you may refer the following link:

http://help.sap.com/businessobject/product_guides/boexir4/en/xi4_rebean_omd.pdf

However, if you can let us know what exactly are you trying to achieve using Report Engine SDK's in BI 4.1, we can try helping you.

Shreyans

[Former Member]

Hi Jerome,

Can you please let us know what exception you are getting in your application and which method from the code is referrencing the class.

The reason being lot of feature were deprecated in ReportEngine SDKs in BI 4.0 and thus the class files are missing.

Please refer to SAP Note:https://support.wdf.sap.corp/sap/support/notes/1587987

Thanks,
