Error retrieving Certificate from Default JKS in PI 7.1 WAS JAVA

Question

Hi everyone.
I'm trying to retrieve a Certificate from the Default JKS of a WAS Java (PI 7.1).
Java code follows:
+InitialContext ctx = new InitialContext(ctxProp);               +
Object o = (Object) ctx.lookup("keystore");
KeyStoreManager manager = (KeyStoreManager) o;
KeyStore keyStore = manager.getKeyStore("DEFAULT");
Certificate ret = ks.getCertificate("ProofCert");
While executing, following Exception arise:
incompatible with interface com.sap.aii.security.lib.KeyStoreManager:sap.com/PIC-WRAPPER-FD-EAR-library-loader
It seems that I need additional libraries:
I have imported that:
import java.security.KeyStore;
import java.security.cert.X509Certificate;
import com.sap.aii.security.lib.KeyStoreManager;
//import java.security.cert.Certificate;
Has anyone some Idea of what is happening? What addiotional libraries I need?
Java version is 5.
Regards,

You need to import the following security libraries:
\usr\sap\<SID>\DVEBMGS00\j2ee\cluster\bin\ext\com.sap.aii.sec.lib\lib\com.sap.aii.sec.lib_api.jar
\usr\sap\<SID>\DVEBMGS00\j2ee\cluster\bin\ext\com.sap.aii.sec.lib\lib\private\com.sap.aii.sec.lib_core.jar
and all the libraries under "security.class".
