Custom JCA Adapter / Application Error - Message.setErrorInfo() ??

[Former Member]

Hi All,

I was looking for how to create a sensible Application Error in a custom JCA adapter and was excited to find the following page in the PCK info on Adapter Development:

http://help.sap.com/saphelp_nw04/helpdata/en/3c/53d6409ff68631e10000000a1550b0/frameset.htm

The part of interest being:

<i>

The following methods are available to enable you to read error information in the form of an ErrorInfo object from the message, or to set the error information in a message.

Message.getErrorInfo()

Message.setErrorInfo()

If the synchronous response message is an application-error message instead of an application response, it must call setErrorInfo(myErrorInfo) for receiver adapters.</i>

However, I can't find these methods, or indeed the "ErrorInfo" object anywhere in the AF classes - does anyone know it's whereabouts? Or is the above page just out of date? If so, what is the new approach for creating Application Level Errors in a custom JCA Resource adapter (not Exceptions - I can do that)

Many thanks,

Chris

Ok, check the following path in your XI or PCK installation:

/usr/sap/<SID>/DVEBMGS<XX>/j2ee/cluster/server0/bin/ext/com.sap.aii.af.lib

or

/usr/sap/<SID>/JC<XX>/j2ee/cluster/server0/bin/ext/com.sap.aii.af.lib

Within 'aii_af_ms_api.jar' is the particular class and method you're looking for.

Also, check Note 766332 for some updated info on adapter development.

Hi Chris -

All the classes required for custom adapter development and the Javadocs are available in the <i>sample_ra.jar</i> archive which you can find on your XI, PCK, or decentral adapter installation. More info <a href="http://help.sap.com/saphelp_nw04/helpdata/en/87/3ef4403ae3db12e10000000a155106/frameset.htm">here</a>. The page is not out of date.

My mistake... "all the classes" aren't in the archive. Let me look for it and get back to you.

Thanks,

Sounds like my issue is an older version of the AF classes.. I have all of them on my classpath in my dev environment, including sample_ra.jar - but the "Message" class mentioned in that help page (I assume this is com.sap.aii.af.ra.ms.api.Message) does not have the mentioned methods. Looks like I need to update the jar files I am using in development environment.

Thanks,

Well, you can get the latest jars from the SMP (Service Marketplace) directly. These jars are in the <i>XI ADAPTER FRAMEWORK CORE 3.0</i> component. Basically, http://service.sap.com/swdc then Support Packages and Patches->SAP NetWeaver->SAP NETWEAVER->SAP NETWEAVER 04->Entry by Component->J2EE Adapter Engine (PI/XI). There you'll see the XI ADAPTER FRAMEWORK CORE 3.0 link.

OR here is the direct link for the SP19 (latest) of <a href="https://smpdl.sap-ag.de/~swdc/012002523100009492712006D/SAPXIAFC19P_4-20000272.sca?_ACTION=DL_DIRECT">SAPXIAFC19P_4-20000272.sca</a>

Within this is <i>aii_af_lib.sda</i> which has the jars. You can use winzip or winrar to open .sca, .sda files.
