It appears when I set

<plugin>
        <groupId>org.teavm</groupId>
        <artifactId>teavm-maven-plugin</artifactId>
        <version>${teavm.version}</version>
        <executions>
          <execution>
            <id>web-client</id>
            <goals>
              <goal>compile</goal>
            </goals>
            <configuration>
                <targetType>WEBASSEMBLY</targetType>   <--- this line

and my Java code looks as follows:

    public static void main(String[] args) {
    }

    @Export(name = "thePurposeOfLife")
    public static int getThePurposeOfLife() {
        return 43;
    }

Any suggestions what to do about it? Thanks for any help in advance!

Same problem. I was testing quarkus and teavm integration. With 0.5.1 no problem but with 0.6.1 or dev builds, no chance. Thanks for any help.

[jbrionne]

With 0.7.0-SNAPSHOT.It works, if i add the lines in team-core > VirtualTableBuilder (line ~367):

    private void buildResultForClass(String className, Context context, VirtualTable parent) {
        TableBuilder table = tables.get(className);
        ClassReader cls = classes.get(className);
        
        if(className.equals("java.lang.Throwable")) {
        	return;
        }

..

The problem comes from: method: fillInStackTrace()Ljava/lang/Throwable; className: java.lang.Throwable

I cannot suggest a correction because I do not know the framework well enough but in any case the problem is here.

Can you provide the code you are trying to compile with TeaVM? Also, what's the reason to use Wasm instead of JS?

[jbrionne]

I was looking for a good framework to compile webassembly from java. The code:

https://github.com/jbrionne/quarkus-webassembly-jdk11

Just exploring !

[konsoletyper]

@jbrionne but what is the purpose of this 'good framework'? What's the purpose of compiling Java to Wasm?

[jbrionne]

It is only in the context of a simple personal technological watch. The webassembly could bring interesting elements in terms of security compared to docker / podman. There is the "Krustlet" project which uses webassembly with kubernetes for example. And why 'java', just because I have a good background on it.

@konsoletyper You don't seem very enamored with wasm. I'm running into the same issue reported here. I'm exploring using wasm to write user defined functions for a database and wasm provides a nice polygot and sandboxed solution. It seems like it it would be a lot better than something like this https://github.com/linkedin/transport

I could just write them in Rust but the database is in Java and it would be nice to offer them a way to write functions in Java as well.
