I really do want to know Java, but my approach to getting there involves backing into it with Perl. The code is the easy part.
I think my hang-up is OO programming in general and trying to visualize the flow from class to interface to method and where each is called and why interfaces can sometimes be instantiated and sometimes not (public vs. private?) In BO there is one Class at the top (for my needs). Everything that follows is an Interface. http://devlibrary.businessobjects.com/BusinessObjectsXI/en/en/BOE_SDK/bo esdk_java_api_doc/doc/boesdk_java_apiRef/doc-files/images/ObjectModel.ht ml All of the Java code examples for the SDK I have been studying seem to rely on casting to instantiate any object beyond the second level. I have played with the type casting in Inline but no success just yet. I may not even be going in the right direction. For example #!/opt/app/p2etl1c1/edsapps/local/bin/perl use Inline Java => ' import com.crystaldecisions.enterprise.ocaframework.ServiceNames; import com.crystaldecisions.sdk.exception.SDKException; import com.crystaldecisions.sdk.framework.CrystalEnterprise; import com.crystaldecisions.sdk.framework.IEnterpriseSession; import com.crystaldecisions.sdk.framework.ISessionMgr; import com.crystaldecisions.sdk.occa.infostore.IInfoStore; import com.crystaldecisions.sdk.occa.pluginmgr.*; import com.crystaldecisions.sdk.plugin.CeProgID; import com.crystaldecisions.sdk.occa.security.IUserInfo; import com.crystaldecisions.sdk.occa.security.ILogonTokenMgr; import java.util.*; import java.io.*; ', STUDY => [ qw( com.crystaldecisions.sdk.exception.SDKException com.crystaldecisions.sdk.framework.CrystalEnterprise com.crystaldecisions.sdk.framework.IEnterpriseSession com.crystaldecisions.sdk.framework.ISessionMgr com.crystaldecisions.sdk.occa.infostore.IInfoObjects com.crystaldecisions.sdk.occa.infostore.IInfoObject com.crystaldecisions.sdk.occa.infostore.IInfoStore com.crystaldecisions.sdk.occa.pluginmgr.IPluginMgr com.crystaldecisions.sdk.occa.security.IUserInfo com.crystaldecisions.sdk.occa.security.ILogonTokenMgr java.lang.Object java.lang.Class ) ], AUTOSTUDY => 1, DEBUG => 1; use Inline::Java qw {cast}; my $sessionMgr = com::crystaldecisions::sdk::framework::CrystalEnterprise->getSessionMgr( ); my $enterpriseSession = $sessionMgr->logon(userid, "password", 'td334.us.company.net:6400', secEnterprise); I get this far. I establish a session and get logged on. After this, I have no success. #Retrieve the InfoStore object $iStore = cast(IInfoStore, $enterpriseSession)->getService("", "InfoStore"); Here I get error "Class IInfoStore not found," but I have had a variety or messages with various tweaks. In other attempts I'm not allowed to do something like this as I expect, and which makes sense to me. $iStore = $enterpriseSession->getService("", "InfoStore"); Error: You are not allowed to invoke method getService in class com.crystaldecisions.sdk.framework.internal.EnterpriseSession: Class InlineJavaUserClassLink can not access a member of class com.crystaldecisions.sdk.framework.internal.EnterpriseSession with modifiers "public" The Java version of the iStore line I'm trying to make perly: IInfoStore iStore = (IInfoStore) enterpriseSession.getService("InfoStore"); A lot for me to learn. Thanks for the reply, Jason. I've posted on two Business Objects development forums without even a nibble. I guess my approach is not very mainstream - unfortunately.

There's no dodging picking up java as you go really. For some things (mostly collections) you'll probably want to evaluate using a tied reference to hide the java behind a familiar perl interface. Otherwise you'll wind up with a leaky abstraction and have java-esque code all through the perl codebase. Other than that, what's the nature if the question? I didn't use Business Objects, but I imagine that they provide some sort of ejb you can get a reference to and make rmi calls on, yes? Otherwise, if it's all via local jars and whatnot, then making sure your class path is correct and using the documented api is probably the way to go and eliminates some complexity.

The STUDY and AUTOSTUDY look like they set me up to do this. Before I get into the specifics of my challenges I was looking for anybody who may have had success doing this. I am having limited success, but I'm not a Java programmer so I'm not even sure how to ask the Java questions to get the Perl answer. Regards, Mike
