import a SHA-256 certificate got error message

Do anyone know why it prompt error 

     1.     command "keytool -genkey keyalg ... " to generate the certificates file, "cacerts" (Result : successfull)

     2.     Use command "keytool -certreq ....."  to generate CSR file (i.e. *.p10)

     3.     sent the p10 file to PKI Support , they generate the certificates (p7b file) and sent back to us.

     4.     Use command "keytool -import "  to import the certificate in to cacerts, e.g.

          keytool -import -trustcacerts -alias validtest -file  certnew-b64.p7b  -keystore cacerts -storepass changeit,  and error is found /w following message.

          keytool error: java.lang.Exception: Certificate chain in reply does not verify: 1.2.840.113549.1.1.11 Signature not available

Java : 1.4.2 update 28

Apache : 2.0.64

Is it the java too old, should we use 1.7 or 1.8 instead?
