I cannot set the signatureKeyAlgorithm to "SHA256withRSA"

On a WSDL containing
```

:





:


```

In SecurityUtil.getKeyAlgo(String algo) algo is always null so returns the default SHA1 algorithm.

In the equivalent dotNet code I have to explicitly set binding.Security.Message.AlgorithmSuite = SecurityAlgorithmSuite.Basic256Sha256. In CXF there is the property override "ws-security.asymmetric.signature.algorithm"

How can I override this in metro?

Start at SecurityUtil.getKeyAlgo(String algo) and trace how the WSDL AlgorithmSuite signatureAlgorithm reaches it, comparing the shown SHA256withRSA policy with the default SHA1 path. Done means the requested signature algorithm can be honored or overridden in Metro, with the behavior verified against this policy example.
