***ERROR*** [generate-sap-entities] Can not get class for byte[]

[yuganESB]

Hi We are using HiberSAP with Jboss forge hibersap plugin. When trying to generate classes for some of BAPIs , we are getting below error:

[TestSAP] TestSAP $ generate-sap-entities --name-pattern Z?EBUS_GETBUS*

Select a function to generate the necessary Java classes:

1 - [Z_EBUS_GETBUSINESSPARTNER] 2 - [Z_EBUS_GETBUSINESSPARTNER_FIX] 3 - [Z_EBUS_GETBUSINESSPARTNER_TMP] 4 - [Cancel]

? Choose an option by typing the number of the selection: 1 _ERROR_ [generate-sap-entities] Can not get class for byte[] [TestSAP] TestSAP $

This error is not coming for all BAPIs in same sap system. But occurring with most of BAPIs. I could not trace any more error messages to share here, Please help me in resolving this error, Thanks in advance.

Hi, this is a bug in Hibersap which is already fixed in the current trunk:

see: https://sourceforge.net/tracker/?func=detail&aid=3566667&group_id=225273&atid=1064492

I am about to do a new Hibersap release 1.1.0; would you mind waiting a few days and use the new version?

To give it a try, you could also build Hibersap from trunk: check out the trunk from svn, go to module "hibersap", run "mvn install -DskipTests -Pdefault" and change the Hibersap version of your project to 1.1.0-SNAPSHOT. You might have to change a few xml element names in your hibersap.xml, since there are some changes in the new version, good news is you can use the xsd provided in the hibersap-core jar or under http://hibersap.sourceforge.net/xml/hibersap_1_1.xsd. If configuring programmatically there are API changes too, which should be quite straight forward using your IDE's auto-completion facilities.

There won't be any further API or XML changes, it's just the documentation which has to be adapted with which I am half-way through - the release should be done till the beginning of next week.

Thanks Cerker for your quick reply. I ill wait for new version. Mean while i will give a try with the changes from Trunk.

Thanks Again.

Hi Cerker

I tried steps suggested by you. Downloaded hibersap-trunk.tar from hibersap trunk. Then mvn install command.. But it failed in my machine.. below are the lines from console. (Still, i tried to genrate classes for the same BAPI by changing repository version in POM to 1.1.0-SNAPSHOT. But it did not work.) Is there any thing to do with HiberSAP-plugin too?

Can you please have a look once.. Please let me know if any thing wrong in steps i executed

Hi Cerker Can you let me know what is the release date of HiberSAP 1.1.0. I tried steps sugggested in above comment, but no luck , i still see same error. Also, in above comments, I posted errors occured while intallation.

Thanks

[cerker]

Hi, I did the new Hibersap release 1.1.0 yesterday. Information can be found under http://hibersap.org.

@Max: Do we need to change something in the Forge plugin? The API, XML schema, etc. should be the same as in the recent 1.1.0-beta releases...

[mxsb]

Hi Carsten,

I need to reference the new version in the plugin pom.xml. Think I'll take 1.1.0 as minimum version in a range, so we will always be up to date without a release.

I want to create a test for the "Can not get class for byte[]" problem, maybe you can give me a hand on this task.

Best regards

Max

Thanks Max for your quick response. I could install Forge 1.1.0 Final and HiberSAP plugin as suggested by you.

Now, am not getting previous error , i.e _ERROR_ [generate-sap-entities] Can not get class for byte[]. But, During the generation of classes , i got below error. As like previous, below error is coming only with BAPIs which were earlier giving 'can not get class for byte[]'. For other BAPIs, am able to generate classes and test the code.

[cerker]

Can you please send the stack trace?
(Issue "set VERBOSE true" and run the "generate-sap-entities" command again in forge to get one.)

[mxsb]

Hi,

I checked the problem and it turns out that the error depends on a bug in Forge. A ticket is already opened and I hope it will be fixed soon.

We'll give you an update when the bug is fixed..

Best regards

Thanks Max and Cerker.. I could test the BAPI now.. All mentioned issues are resolved. Many Thanks for your support..
