I get this error when I try to query my "jolokia" agent.

curl  http://localhost:8778/jolokia/list

I've launched my java application (kibana) with the jolokia agent, as explained in the Manual https://jolokia.org/reference/html/agents.html#agents-jvm.

java -javaagent:agent.jar=port=8778,host=localhost

I can see (ps -aux) that the process launched with the jolokia agent in between the Java Arguments.
I have also tried to deploy the jolokia war in my Tomcat /webapps. I've edited the user.xml file to add the User Jolokia, but I get the same result
The only result I get by googling the error seems to be the Jolokia code, at line 287, which seems to imply the host or address are wrong, but i'm doing everything from localhost, which should be allowed. https://github.com/rhuss/jolokia/blob/master/agent/core/src/main/java/org/jolokia/http/HttpRequestHandler.java
Am I missing some settings? which is the best way to test it? I have zero experience with Java applications and Jolokia.

tomcat

Jolokia默认设置设置为阻止apache-activemq/webapps/API/WEB-INF/classes/jolokia-access.xml文件中的所有CORS。

<cors>
 <strict-checking/>
</cors>

您可以通过删除上述配置或在严格检查之前添加允许的来源来禁用它。

<cors>
 <!-- Allow cross origin access from www.jolokia.org ... -->
 <allow-origin>http://www.jolokia.org</allow-origin>

 <!-- ... and all servers from jmx4perl.org with any protocol ->
 <allow-origin>*://*.jmx4perl.org</allow-origin>

 <!-- Check for the proper origin on the server side, too -->
 <strict-checking/>
</cors>

根据您当前的配置需要更改。根据您的确切错误行，您需要在您的http请求中添加“起源”标头。
例如-curl http://localhost:8778/jolokia/list -H "Origin:http://localhost"
请记住，如果启用了默认CORS，请在<cors>标记下添加<allow-origin>例外。

Jolokia的默认设置将阻止所有CORS

<cors>
        <!-- Allow cross origin access from localhost ... -->
        <allow-origin>*://localhost*</allow-origin>

        <!-- Options from this point on are auto-generated by Create.java from the Artemis CLI -->
        <!-- Check for the proper origin on the server side, too -->
        <strict-checking/>
    </cors>

</restrict>

只需从jolokia-access.xml中的上述默认配置中删除<strict-checking/>标记
