Error binding json to java object

This is a follow up question for this post
I tried to make an implementation based on Stephan Van Hulst's tip, but getting following error:

Exception in thread "pool-2-thread-1" javax.json.bind.JsonbException: JSON Binding provider org.eclipse.yasson.JsonBindingProvider not found    at javax.json.bind.spi.JsonbProvider.provider(JsonbProvider.java:120)    at javax.json.bind.JsonbBuilder.create(JsonbBuilder.java:123)    at net.goanation.services.BitPandaService.getAveragePrice(BitPandaService.java:182)    at net.goanation.services.BitPandaService.getMarketTicker(BitPandaService.java:67)    at net.goanation.MainApp.lambda$start$0(MainApp.java:46)    at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source)    at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)    at java.base/java.lang.Thread.run(Unknown Source) Caused by: java.lang.ClassNotFoundException: org.eclipse.yasson.JsonBindingProvider    at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(Unknown Source)    at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(Unknown Source)    at java.base/java.lang.ClassLoader.loadClass(Unknown Source)    at java.base/java.lang.Class.forName0(Native Method)    at java.base/java.lang.Class.forName(Unknown Source)    at javax.json.bind.spi.JsonbProvider.provider(JsonbProvider.java:117)    ... 7 more

Although I added both dependencies needed:

  <dependency>       <groupId>org.eclipse</groupId>       <artifactId>yasson</artifactId>       <version>2.0.0-M2</version>  </dependency>  <dependency>       <groupId>javax.json.bind</groupId>       <artifactId>javax.json.bind-api</artifactId>       <version>1.0</version>   </dependency>

When googling the error online I saw that they used:

<dependency>           <groupId>org.glassfish</groupId>           <artifactId>javax.json</artifactId>           <scope>provided</scope>       </dependency>

While I was using

<dependency>            <groupId>org.json</groupId>            <artifactId>json</artifactId>            <version>20150729</version>        </dependency>

but changing that resulted in:

Exception in thread "pool-2-thread-1" javax.json.bind.JsonbException: JSON Binding provider org.eclipse.yasson.JsonBindingProvider could not be instantiated: java.lang.ClassCastException: class org.eclipse.yasson.JsonBindingProvider cannot be cast to class javax.json.bind.spi.JsonbProvider (org.eclipse.yasson.JsonBindingProvider and javax.json.bind.spi.JsonbProvider are in unnamed module of loader 'app')    at javax.json.bind.spi.JsonbProvider.provider(JsonbProvider.java:122)    at javax.json.bind.JsonbBuilder.create(JsonbBuilder.java:123)    at net.goanation.services.BitPandaService.getAveragePrice(BitPandaService.java:182)    at net.goanation.services.BitPandaService.getMarketTicker(BitPandaService.java:67)    at net.goanation.MainApp.lambda$start$0(MainApp.java:46)    at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source)    at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)    at java.base/java.lang.Thread.run(Unknown Source) Caused by: java.lang.ClassCastException: class org.eclipse.yasson.JsonBindingProvider cannot be cast to class javax.json.bind.spi.JsonbProvider (org.eclipse.yasson.JsonBindingProvider and javax.json.bind.spi.JsonbProvider are in unnamed module of loader 'app')    at javax.json.bind.spi.JsonbProvider.provider(JsonbProvider.java:118)    ... 7 more

Any idea how come?

You're probably using incompatible versions of the JSON-B API and its implementation (Yasson).

I can give you the exact Maven coordinates if you give me a few hours. I'm on my phone right now.

This is what you need:
   <dependency>      <groupId>jakarta.json.bind</groupId>      <artifactId>jakarta.json.bind-api</artifactId>      <version>1.0.2</version>    </dependency>        <dependency>      <groupId>org.eclipse</groupId>      <artifactId>yasson</artifactId>      <version>1.0.7</version>      <scope>runtime</scope>    </dependency>

For future reference: Java EE is now called Jakarta EE, so you will find new versions of most enterprise APIs (like JSON-B) under a group ID that starts with jakarta.

Furthermore, don't rely on alpha/beta/RC versions of a dependency unless you really need to and know what you are doing. A general guideline is when the version of a plugin contains letters, don't use it.

Thanks Stephan, you're awesome, you must be Belgian , (more likely Dutch, but anyways...)

I'm South African, but raised in the Netherlands.

Yeah your name sounded Dutch, but being from south-africa that not all weird, in any case, dankie, with your guidance I was abble to make it work and th eobjects are finally being populated
