Support/Alternative of Nashorn with Spring Native

Support/Alternative of Nashorn with Spring Native - java

In my company we use Nashorn in Java 11 and spring-boot which is working fine, but we recently decided to use spring-native with docker. We ended up to make the image build, but at startup, the project crash because the Nashorn is not supported (And will probably be never supported by graalVM).
Here is the error I get when tring to run the native image
We can't migrate easily from Nashorn to GraalVM.js and the deadline are short, so it's not a solution for us.
I'm asking here if you already had the issue, and how you overcame it.
I already tried to change the ScriptEngine from 'nashorn' to 'js' (which is available in my project), but it also failed at run time. We basically need for an engine which don't use 'invokedynamic' to compute js code.
An other solution would be : Export the Nashorn part as an external microservice.
But we prefere avoid using this solution, since the current implementation is working and it would add some security issue to considere to secure the communication. We will considere it only if we run out of solution ^^'
Here is the problematic code :
Engine.java
public class Engine {
public Engine() {
ScriptEngineManager manager = new ScriptEngineManager();
engine = manager.getEngineByName("nashorn");
}
}

Part 1.
Migration from Nashorn to GraalVM.js is standard topic and covered in documentation
https://www.graalvm.org/reference-manual/js/NashornMigrationGuide/
And most likely there will not be alternative (at least developed by Oracle)
Part 2. Spring Native (still experimental) is ongoing effort to build Spring application using native-image compiler from GraalVM to produce native-image. This project focuses on Spring project and js support will be out of scope, you would need again follow Oracle work.
During this native-image build, the engine like GraalVM.js (that is graalVM component) must be included into resulted app, and it may be non trivial.
And life advice: if you really under deadline, consider going with older technologies if you want to guarantee delivery. And use JDK before JDK15 where Nashorn is still present.

Java Implementation of JAXB-API has not been found on module path or classpath

I have an application that should work, but here I have a JAXB error. I don't know which version of Java it is, I think it's 8.
I run in Java 8. In Java 8+ iIhave to add javax.xml.bind and com.sun.xml.bind to pom. I also ran it with Java 11 and 16 and jakarta in the pom.
I have read that applications which are supposed to run on Java 8 but were running it on Java 11, generate this error, and that has jous in the pom of jakarta and javax.
And another question how to detect the Java to use? And that the solution applies according to the version of java
I have this error.

Spring Boot application fails to run - spring.resources.cache-period were left unbound

I'm having difficulties with my Spring Boot application which is not willing to run.
According to logs the reason of this situation is unbound spring.resources.cache-period property.
This property however is set in application.properties and compiler is even returning it's value.
I'll really appreciate if someone could lend me a hand with that issue.

application.properties

Just as #Stephane Nicoll suggested, I've changed spring-boot-devtools version to the one corresponding my Spring Boot version. This, along with deletion of previously provided spring.resources.cache-period property solved the issue.

I had the same problem.
You should remove the version to use spring-boot same version
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
</dependency>

Also be aware of your user's global configuration file for devtools:
~/.spring-boot-devtools.properties
This might have deprecated values like the mentioned spring.resources.cache-period in it, that are no longer valid.
=> In my case, removing this old value solved the same error!
Also have a look at spring boot's documentation for the order of configurations:
https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html#boot-features-external-config-application-property-files

DynamoDB mapper class missing in dynamodb client

I want to use dynamodb client by declaring following artifacts in my project
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>dynamodb</artifactId>
</dependency>
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>dynamodbmapper-v1</artifactId>
<version>1.0.0</version>
</dependency>
Both of the above jars not contain classes related to dynamodb.
But if see the artifacts downloaded by using following GAV then i see the classes in extracted jar.
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-dynamodb</artifactId>
Whats the difference between group com.amazonaws and software.amazon.awssdk and where is there a difference?
Why is the mapper missing in the first GAV.
Amazon mentions following in the first artifact
<artifactId>dynamodbmapper-v1</artifactId>
<name>AWS Java SDK :: Test :: Amazon DynamoDB Mapper v1</name>
<description>DynamoDB Mapper largely unchanged from v1. The v1 Mapper is kept for testing purposes only. All classes are in the test directories to prevent use in application code.</description>
<url>https://aws.amazon.com/sdkforjava</url>

Personally I don't like the amazon documentation - I'm not sure if this is your case but, for me, most of the time the material there is outdated.
I'm using the aws client and the Lavelle community dynamo library to make some queries into DynamoDB via annotations / querydsl.
Below follows my pom.xml for a spring-boot/spring-data/dynamodb/swagger micro service.
I hope it helps.

Google Cloud Storage Runtime Error

I'm simply trying to list the contents of my Google Cloud Storage bucket from my GAE (java) using the following code:
GcsService gcsService = GcsServiceFactory.createGcsService(new RetryParams.Builder()
.initialRetryDelayMillis(10)
.retryMaxAttempts(10)
.totalRetryPeriodMillis(15000)
.build());
try{
ListResult list = gcsService.list("MyTestBucket", new ListOptions.Builder().setPrefix("testFolder").setRecursive(true).build());
}
It compiles, but when I run it I get the following error which I don't understand:
Caused by: java.lang.NoSuchMethodError: com.google.appengine.tools.cloudstorage.GcsService.list(Ljava/lang/String;Lcom/google/appengine/tools/cloudstorage/ListOptions;)Lcom/google/appengine/tools/cloudstorage/ListResult;
The POM dependency looks like this to include Google Storage:
<dependency>
<groupId>com.google.appengine.tools</groupId>
<artifactId>appengine-gcs-client</artifactId>
<version>0.6</version>
</dependency>
I've tried various <exclusions> but can't seem to make it work.
Thanks
Tim

Fixed it! I looked in the .war file and found that there were two versions of the appengine-gcs-client jar files. 0.2 and 0.6. I did an mvn clean and it sorted the problem. I really should have done that before :-( Live and learn!

Try removing <enableJarClasses>false</enableJarClasses>. I suspect this is causing the JAR for the GCS library not be be included in the artifact ran on GAE. As a result required classes might be missing.

Maven: Non Resolvable parent POM for com.example.speech:speech-google-cloud-samples

I tried using speech to text using google speech client from github:
https://github.com/GoogleCloudPlatform/java-docs-samples/tree/master/speech/cloud-client
In pom.xml it shows the following issue:

How do i fix this problem? Sorry for the long code..

Your title, and the content of your post show two different problems. I'm going to respond to the one described by the content of your post.
Your problem is a classic eclipse-integration problem; that is, you need to instruct eclipse what to do with various plugins that your pom references (you probably want to ignore them).
So in your situation, you need to copy/paste the below code in your pom; this will have effect only in Eclipse, and be ignored otherwise. Please note that you are likely to get the same error for other plugins as well, so you need to repeat/adapt the process for any similar errors you might get.
