我必须在 WebLogic Bea 10.0 M1 服务器环境中执行长时间运行的线程。我尝试为此使用 WorkManagers。使用自己的 WorkManager 允许我指定自己的线程超时 (MaxThreadStuckTime),而不是调整整个业务应用程序的超时。
我的设置如下:
weblogic-ejb-jar.xml:
<?xml version="1.0" encoding="UTF-8"?>
<weblogic-ejb-jar xmlns="http://www.bea.com/ns/weblogic/90" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.bea.com/ns/weblogic/90 http://www.bea.com/ns/weblogic/90/weblogic-ejb-jar.xsd">
<weblogic-enterprise-bean>
<ejb-name>TestBean</ejb-name>
<resource-description>
<res-ref-name>myWorkManager</res-ref-name>
<jndi-name>wm/myWorkManager</jndi-name>
</resource-description>
</weblogic-enterprise-bean>
</weblogic-ejb-jar>
weblogic-application.xml:
<?xml version="1.0" encoding="UTF-8"?>
<weblogic xmlns="http://www.bea.com/ns/weblogic/90" xmlns:j2ee="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.bea.com/ns/weblogic/90
http://www.bea.com/ns/weblogic/90/weblogic.xsd">
<work-manager>
<name>myWorkManager</name>
<ignore-stuck-threads>1</ignore-stuck-threads>
</work-manager>
</weblogic>
和豆子:
import javax.annotation.Resource;
import javax.ejb.Stateful;
import weblogic.work.WorkManager;
@Stateful(mappedName = "TestBean")
public class TestBean implements TestBeanRemote {
@Resource(name = "myWorkManager")
private WorkManager myWorkManager;
public void test() {
myWorkManager.schedule(new Runnable() {
public void run() {
while (true) {
System.out.println("test: +++++++++++++++++++++++++");
try {
Thread.sleep(45000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
});
}
}
当我尝试部署这些东西时,服务器给了我以下异常:
[EJB:011026]The EJB container failed while creating the java:/comp/env namespace for this EJB deployment.
weblogic.deployment.EnvironmentException: [EJB:010176]The resource-env-ref 'myWorkManager' declared in the ejb-jar.xml descriptor has no JNDI name mapped to it. The resource-ref must be mapped to a JNDI name using the resource-description element of the weblogic-ejb-jar.xml descriptor.
我试图弄清楚如何访问/使用 WorkMangers 好几天了,但仍然把这个或那个作为一个例外。非常令人沮丧!
提前致谢!
