The clash between these two contrasting styles promises an intriguing contest where strategy will be key. While Player A aims to dominate with power and aggression, Player B will rely on precision and adaptability to counter those strengths.
Betting Tips for Match 1
- If you're inclined towards safer bets, consider backing Player A due to their current form advantage; however, don't discount potential value in betting against them if you believe Player B can exploit any weaknesses during extended rallies or break points.>
- A popular betting strategy is placing parlays that include multiple outcomes within the match—such as betting on sets won or specific game scores—to maximize potential returns while managing risk effectively.>
Analyzing Key Statistics
Average First Serve Percentage
An essential statistic that often determines who gains control early in rallies is first serve percentage. Higher percentages typically lead to more service games won as opponents struggle against well-placed serves aimed at corners or bodylines.
Average Rally Length
Rally length can provide insights into how closely contested matches may be; longer rallies suggest evenly matched competitors vying for every point through strategic shot placement rather than outright power dominance alone—this could benefit players like B known for endurance over speedier counterparts like A who rely more heavily upon immediate aggression rather than extended exchanges.

<|file_sep|># helidon-microprofile-jwt-authentication
This project demonstrates how [Helidon Security](https://helidon.io/docs/security/) can be used to implement [MicroProfile JWT Authentication](https://microprofile.io/project/eclipse/microprofile-jwt-auth/1.2/) specification.
The project contains two modules:
* `helidon` - Helidon SE server which implements MicroProfile JWT Authentication specification based on Helidon Security library.
* `test-client` - REST client application which tests functionality of `helidon` module.
## Build
To build this project run following command:
mvn clean install -P skip-tests
## Configuration
This project uses [YAML](https://yaml.org/) format configuration file located at `src/main/resources/config.yaml`.
This configuration file contains configuration related to JWT authentication.
## Usage
### Run Helidon SE server
To start Helidon SE server run following command:
java -jar target/helidon-microprofile-jwt-authentication-helidon.jar
### Test functionality
To test functionality run following command:
java -jar target/helidon-microprofile-jwt-authentication-test-client.jar
You should see output similar as below:

<|file_sep|># Configuring security
## Creating security instance
Security instance is created using `Security.builder()` factory method.
java
var security = Security.builder()
.addProvider(SecurityProvider.NONE)
.addProvider(SecurityProvider.BASIC_AUTH)
.addProvider(SecurityProvider.JWT_AUTH)
.create();
## Configuring providers
Providers are added using `addProvider()` method.
java
var security = Security.builder()
.addProvider(SecurityProvider.NONE)
.addProvider(SecurityProvider.BASIC_AUTH)
.addProvider(SecurityProvider.JWT_AUTH)
.create();
## Configuring Basic Auth provider
Basic Auth provider is configured using `withBasicAuthProvider()` method.
java
var basicAuthProvider = BasicAuthProvider.create()
.withRealm("hello-world")
.withRealmConfig(RealmConfig.create()
.withUser("user")
.withPassword("password"))
.create();
Basic Auth provider can be added using `Security.builder()` factory method as shown below:
java
var security = Security.builder()
.addProvider(basicAuthProvider)
.create();
Or by calling `Security.builder().withBasicAuthProvider(...)` factory method as shown below:
java
var security = Security.builder()
.withBasicAuthProvider(basicAuthProvider)
.create();
## Configuring JWT Auth provider
JWT Auth provider is configured using `JwtAuth.create()` factory method.
java
var jwtAuthProvider = JwtAuth.create()
// Add custom configuration if required.
// By default it reads configuration from application.yaml file.
// See https://github.com/oracle/helidon/blob/master/security/src/main/java/io/helidon/security/jwt/JwtAuth.java#L47-L53
//.withConfig(config)
// Configure RSA public keys used for token validation.
// By default it reads keys from application.yaml file.
// See https://github.com/oracle/helidon/blob/master/security/src/main/java/io/helidon/security/jwt/JwtAuth.java#L55-L60
//.withRsaPublicKey(RsaKeyPairUtils.loadRsaPublicKey("/path/to/public/key"))
// Configure JWK public keys used for token validation.
// By default it reads keys from application.yaml file.
// See https://github.com/oracle/helidon/blob/master/security/src/main/java/io/helidon/security/jwt/JwtAuth.java#L62-L67
//.withJwkPublicKey(JwkKeySetUtils.loadJwkPublicKey("/path/to/public/key"))
// Configure allowed signing algorithms used by JWT token signature.
// By default it uses HS256 algorithm if RSA or JWK keys are not configured.
// See https://github.com/oracle/helidon/blob/master/security/src/main/java/io/helidon/security/jwt/JwtAuth.java#L69-L73
//.withAllowedSigningAlgorithms(List.of("HS256", "RS256"))
// Configure allowed claims types used by JWT token signature.
// By default it uses "none" claim type if RSA or JWK keys are not configured.
// See https://github.com/oracle/helidon/blob/master/security/src/main/java/io/helidon/security/jwt/JwtAuth.java#L75-L79
//.withAllowedClaimsTypes(List.of("none", "RS256"))
// Configure roles mapper which maps JWT token claims values
// onto user roles defined by application implementation
//.withRolesMapper(rolesMapper)
