Adapter Module Development -- Getting FileName

[Former Member]

Hi All,

I have following problem faced in Adapter Module Development.

My Deployment shows perfect but when used it throws following error:

Error: java.lang.ClassCastException: class com.sap.zfilename.Zsrinifilename_finalLocalHomeImpl0_0 can not be casted to ModuleLocalHome or SModuleLocalHome

Attempt to process file failed with java.lang.ClassCastException: class com.sap.zfilename.Zsrinifilename_finalLocalHomeImpl0_0 can not be casted to ModuleLocalHome or SModuleLocalHome

Following has been done:

Went to the Visual Admin and checked Ejb is active and changed the jndi name as mentioned above also.

Wat could be the problem now still ??

kindly advice

thx in advance

Hi

Are you implementing these two interfaces?

javax.ejb.SessionBean &

com.sap.aii.af.mp.module.Module

[Former Member · Accepted solution]

hi,

yes am using two interfaces kindly check below

public class Zsrinifilename_finalBean implements SessionBean,Module {

I guess i should check if .ear file has some library files , but i donno how to check those things

rest things i had a check seems to be fine.

thx in advance for help

if i see in the CC Monitoring in RWB

Error: org.xml.sax.SAXParseException: Document root element is missing.

What could be the cause

Srini

[stefan_grube · Accepted solution]

Did you put your module in the module chain before the SAP module?

Maybe you post your code, to see if there is an issue inside.

Kindly revert back if anything to be changed

[stefan_grube · Accepted solution]

Change this:

if (mp != null) 
    fileName = (String) mp.get("FileName");

to

if (mp != null)
    fileName = (String) mp.get("FileName");
else 
    fileName = "default";

As you have use the code from teched session is template, you should enhance the code for audit log entries to see, what happens on runtime.

Regards

Stefan

[stefan_grube · Accepted solution]

What do you want to achieve with this part of code?

Hashtable mp = (Hashtable)
inputModuleData.getSupplementalData("module.parameters");
if (mp != null) fileName = (String)
mp.get("FileName");

[stefan_grube · Accepted solution]

Better change this:

String fileName = null;

to

String fileName = "default";

Kindly advice which .jar files should i , delete and deploy.

Advice needed

[stefan_grube]

Check the EAR file, if there are any additional libraries inside.

If so, delete them before deploying.

Hi Stefan,

I am new to this adapter module development and ejb stuffs..

am using NWDS , kindly step me out om which i should click and check if i have any additinal library files.

kindly step me out..Should i right click "Enterprise Application Project" and check properties.

where should i ??

plz reply back urgent

Yes, use Winzip. Java libraries (jar, ear, war, rar, sda, sca) can be extracted be WinZip.

You can delete the additional jars with WinZip also.

You can assossiate ear with winzip once, then you can do this directly from NWDS.

Stefan

Hi stefan,

lemme know how to do this using NWDS,

i right click on .ear and say open it doesnot show up anything , i went and searched for .ear file in the local owrkspace but couls not find...

am in a lag ... now i can see .ear in my NWDS , from now how to proceed , to see if there any additinal libraries and delete them if any present,

Advice

thx

srini

[stefan_grube]

Check, where your EAR file is stored in the file system. You can see this in properties.

Go to the file system and open it with winzip and check "alwasy open with". Then you can open it from NWDS directl with winzip.

it should be in <workspace>/<EARproject>
