custom component import can't find jar

hzhen — Fri, 02 Jan 2026 14:45:42 GMT

Thanks.

The JAR I made was quoted in the component I developed. After importing it in TOS, it prompts success, but an error occurs when opening TOS.(Jp.co.nec.webservice.cxf.client.Factory) is the code in my Jar, and the Jar used is also imported into the maven library when importing .car

java.lang.ClassNotFoundException: jp.co.nec.webservice.cxf.client.Factory
