我正在使用以下代码触发从camel到jbpm的进程。
from("timer://foo?fixedRate=true&period=500&repeatCount=1").routeId("mainRoute")
.to("log:Hello?showAll=true&multiline=true")
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
`enter code here`for (Object obj : exchange.getIn().getHeaders().entrySet()) {
Map.Entry<String, Object> entry = (Map.Entry<String, Object>) obj;
System.out.println(entry.getKey() + "/" + entry.getValue());
}
final Map map = new HashMap();
map.putAll(exchange.getIn().getHeaders());
map.put("pv_candidate_name", "Hello");
exchange.getOut().setHeader("CamelJBPMParameters", map);
}
})
.setHeader(JBPMConstants.PROCESS_ID, constant("npproj.emp_recruitment3"))
.to("jbpm:http://127.0.0.1:8080/kie-wb64?userName=admin&password=xxx&deploymentId=com.nobleprog:npproj:1.0")
.convertBodyTo(String.class)
.to("log:Hello?showAll=true&multiline=true");
我登录到bpm系统并尝试执行任务，在jbpm中收到以下错误。

我是否需要jbpm中的任何配置？请指导
答案 0 :(得分：0)
解决。 将这些路径添加到wildfly 8中的sun / jdk / main / module.xml文件中。
path name="com/sun/org/apache/xerces/internal/jaxp/datatype"
path name="com/sun/jndi/rmi"
试图找到原因。
