当我尝试从eclipse运行optaplanner 6.3.0-SNAPSHOT web示例时（在使用maven构建并在服务器上运行之后）。我得到以下异常，我试图将war（直接下载源代码）文件直接部署到tomcat，几乎同样的错误显示在那里

答案 0 :(得分：0)

通过替换项目web.xml文件中的以下代码，我成功地在tomcat中运行了6.3 web示例：

    <servlet-mapping>
        <servlet-name>javax.ws.rs.core.Application</servlet-name>
        <url-pattern>/rest/*</url-pattern>
    </servlet-mapping>

这个servlet配置代码（取自6.2 web示例）：

<servlet>
    <servlet-name>VrpShowScheduleServlet</servlet-name>
    <servlet-class>org.optaplanner.webexamples.vehiclerouting.VrpShowScheduleServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>VrpShowScheduleServlet</servlet-name>
    <url-pattern>/vehiclerouting/showSchedule.png</url-pattern>
</servlet-mapping>

答案 1 :(得分：0)

我以这种方式运行Optaplanner Web示例（版本7.23.0.Final）。

step0 ，从OptaPlanner website下载optaplanner-distribution-7.23.0.Final.zip并解压缩分发包，找到optaplanner-webexamples.war。

step1 ，编写一个Dockerfile。

FROM jboss/wildfly:14.0.1.Final
MAINTAINER zbr

COPY ./optaplanner-webexamples.war /opt/jboss/wildfly/standalone/deployments/optaplanner-webexample.war

RUN /opt/jboss/wildfly/bin/add-user.sh admin admin456 --silent

CMD ["/opt/jboss/wildfly/bin/standalone.sh", "-b", "0.0.0.0", "-bmanagement", "0.0.0.0"]

step3 ，构建docker映像。

docker build -t optaplanner-webexample:latest .

第4步，运行。

docker run -ti --rm -p 8080:8080 -p 9990:9990 optaplanner-webexample:latest

第5步，测试。

firefox http://localhost:8080/optaplanner-webexample

有效。
