JavaPS eating Errors about javaps

[bpross-52n]

Can you give us some code examples? Logging errors seems to work for me, if using an annotated algorithm.

Its more accurate to say it eats the stacktraces. When I throw this error JavaPS's default behavior is to show the error code but the stacktrace is lost.

@Slf4j
@Algorithm(version = "1.0.0")
public class TestAlgorithm {

    private String input;
    private String output;

    @LiteralInput(
            identifier = "input")
    public void setInput(String param) {
        this.input= param;
    }

    @LiteralOutput(
            identifier = "output")
    public String getOutput() {
        return this.output;
    }

    @Execute
    public void runAlgorithm() throws Exception {
        throw new Exception("This is a test error");
    }
}

Error in javaps.log:

2020-06-25 09:27:57,645 ERROR o.n.j.e.i.EngineImpl [javaps-0] JobId{value=ea6044c0-145f-46d6-86ed-a7fc3ed853c7} failed: This is a test error

Desired stackstrace output in javaps.log:

Additionally logging doesn't seem to work unless an error is thrown from my algorithm.

@Slf4j
@Algorithm(version = "1.0.0")
public class TestAlgorithm {

private String input;
private String output;

@LiteralInput(
        identifier = "input")
public void setInput(String param) {
    this.input= param;
}

@LiteralOutput(
        identifier = "output")
public String getOutput() {
    return this.output;
}

@Execute
public void runAlgorithm() throws Exception {
    log.error("This does not log.");
}
}

The default log level for org.n52 loggers is trace and for all others (well, except for Spring) it is warn.

Unless you changed the default logging configuration, or if you're using Docker, which has a slightly different configuration, the stack trace of each and every exception should be logged on debug.

As the log level for the org.n52.javaps.engine.impl.EngineImpl logger is trace, the stack trace should definitely appear in your logfile...

Could you show us the log4j2.xml that is used?

[overbound]

The original log XML file was still overriding my attempts at configurations. I was able to replace the existing log XML and that fixed what I was seeing and makes good sense. So this is a non-issue and I will close. Thanks!
