Christian commented on OLTU-126:
--------------------------------
Possible solution: Override GrantType's valueOf method.
{code:title=GrantType.java}
public static GrantType valueOf(String name) {
if (name == null)
throw new NullPointerException("Name is null");
for (GrantType value : GrantType.values()) {
if (value.toString().equals(name)) {
return value;
}
}
throw new IllegalArgumentException(
"No enum constant " + GrantType.class.getCanonicalName() + "."
+ name);
}
{code}
> No enum constant GrantType.password

> Key: OLTU-126
> URL: https://issues.apache.org/jira/browse/OLTU-126
> Project: Apache Oltu
> Issue Type: Bug
> Components: oauth2-authzserver, oauth2-client, oauth2-common
> Affects Versions: 0.31
> Environment: JBoss 7.1.1
> Reporter: Christian
> Priority: Critical
>
> There seems a problem with de-/serialization of GrantTypes. When using the
> Oltu client for own services, the GrantType is serialized by the
> toString()-method, which returns lower case identifiers.
> OAuthClientRequest request = OAuthClientRequest
> .tokenLocation("http://localhost:8080"; + CONTEXT_PATH +
> "/oauth2/token")
> .setClientId("test")
> .setGrantType(GrantType.PASSWORD)
> .setUsername(email)
> .setPassword(password)
> .buildBodyMessage();
> OAuthClient oAuthClient = new OAuthClient(new URLConnectionClient());
> OAuthJSONAccessTokenResponse oauthResponse =
> oAuthClient.accessToken(request);
> While on the server OAuthUnauthenticatedTokenRequest's constructor will call
> GrantType.valueOf(String), which only accepts upper case identifiers.
> That results in an exception:
> java.lang.IllegalArgumentException: No enum constant
