Problem with Java Mapping - NoClassDefFoundError exception

[Former Member]

Hi mates,

I'm facing a problem with my java mapping program.

The scenario is a RFC -> XI - HTTP, synchronous interface, where i receive some data from the ECC system and i need to sign and envelope this data, using the pattern PKCS#7, and send it to my HTTP Server using HTTPS protocol.

The problems occurs when i try to use the IAIK library (iaik_jce.jar), to sign and envelope my message.

The error message returned is (At SXMB_MONI):

[code]

<SAP:Code area="MAPPING">LINKAGE_ERROR</SAP:Code>

The IAIK JCE library already exists in the J2EE engine, because it's needed to use the KeyStorage Service.

In mt java code, i use the following includes:

[code]

import iaik.asn1.ASN1Object;

import iaik.asn1.ObjectID;

import iaik.asn1.structures.AlgorithmID;

import iaik.asn1.structures.Attribute;

import iaik.asn1.structures.ChoiceOfTime;

import iaik.pkcs.pkcs7.EnvelopedDataStream;

import iaik.pkcs.pkcs7.IssuerAndSerialNumber;

import iaik.pkcs.pkcs7.RecipientInfo;

import iaik.pkcs.pkcs7.SignedData;

import iaik.pkcs.pkcs7.SignedDataStream;

import iaik.pkcs.pkcs7.SignerInfo;

import iaik.security.provider.IAIK;

import iaik.x509.X509Certificate;

[/code]

What it's wrong with my java mapping? Any clues?

Is there any compactibility problem with the IAIK lib?

Is the IAIK lib the "standard" way to access the KeyStorage service and sign data in XI/NetWeaver?

Thanks in advance,

Hi Jose,

Please import the IAIK jar into repository, in "Imported Archives" and try again.

Reward points if helpful.

Regards.
