java.lang.NoClassDefFoundError: com/sap/mdi/ddtypes/DDObject

[Former Member]

Hi,

I have an iView that makes a R/3-connection and receives a result-table. I can get the metadata of the table

IRecordMetaData meta = structure.retrieveMetaData();

and I can ask the metadata about the column-count and column-names

for (int i = 0; i < meta.getColumnCount(); i++) {

String columnName = meta.getColumnName(i);

}

but asking for the column-type

meta.getColumnType(i);

raises the error "java.lang.NoClassDefFoundError: com/sap/mdi/ddtypes/DDObject"

Does anyone have any idea?

Thanks and Regards

You could do either of the following two things.

1. Add SAPmdi.jar to Portal-INF->lib folder of your par project.

2. add the following line: "reference service:eisconnector library:com.sap.mdi" to the reference.txt file

PS: Please reward points if the problem is resolved.

Hi,

Thanks for the response. I added the SAPmdi.jar into Portal-INF->lib and also added reference "service:eisconnector library:com.sap.mdi" into portalapp.xml file but it gives me the error "couldn't find the portal application com.sap.mdi".

How different is reference.txt file from portalappp.xml.

Thanks and Regards

Hi Padmaja,

Don't add it to the portalapp.xml. <b>I never told you to add it to the portlapp.xml.</b> If you are going to <b>add the SAPmdi.jar to portal-info->lib directory then you don't need to add the line in reference.txt</b>. Reference.txt is a global file for storing all the references to the library being used by portal. Test your code without adding it to your portlapp.xml and it will work.

Hi,

I get the error "Java.lang.NoClassDefFoundError:com/sap/mdi/ddtypes/DDObject" even now. Is there any problem with the JCA in my portal.

Thanks and Regards

DDObject is part of SAPmdi.jar. Can you tell me what version of portal do you have? Can you send me your project at singhpra@yahoo.com.

Hi,

My portal version is EP6 SP2. I will send my par file to your id.

Thanks and Regards
