Oracle soap seems to have a problem with HTTPS. When I try to connect to a secure web service (using jdeveloper 10g preview), the following error is displayed:
[SOAPException: faultCode=SOAP-ENV:IOException; msg=javax.net.ssl.SSLException: SSL handshake failed: X509CertChainIncompleteErr; targetException=java.io.IOException: javax.net.ssl.SSLException: SSL handshake failed: X509CertChainIncompleteErr]
at org.apache.soap.SOAPException.<init>(SOAPException.java:78)
at oracle.soap.transport.http.OracleSOAPHTTPConnection.send(OracleSOAPHTTPConnection.java:765)
at org.apache.soap.rpc.Call.invoke(Call.java:261)
To solve this problem you need to replace some of Oracle’s jar files with the ssl library which comes with the sun jdk. You can find this solution on Mike Lehmann’s blog
