编辑web.xml文件时，

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

提示以下信息：

cvc-complex-type.2.4.a: Invalid content was found starting with element 'init-
param'. One of '{"http://java.sun.com/xml/ns/j2ee":run-as, "http://java.sun.com/
xml/ns/j2ee":security-role-ref}' is expected.

可把 <load-on-startup>0load-on-startup> 移动到最后即可.

Dictionary OSGi Service模板Custom端使用

Mitool — Sun, 14 Nov 2010 05:02:00 GMT

Eclispe 插件工程中提供了Dictionary OSGi Service 模板，写了一下Custom端使用的代码。

1. Dictionary OSGi Service 模板
按照Eclipse向导生成。注意Export相应包。

2. Custom 端使用
新建插件工程，Import字典服务Exprot的包。

代码片段：

package demo.dictionary.custom;

import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
import org.osgi.framework.ServiceReference;

import demo.dictionary.DictionaryService;

public class Activator implements BundleActivator {
    ServiceReference serviceReference = null;

    public void start(BundleContext context) throws Exception {
        serviceReference = context.getServiceReference(DictionaryService.class.getName());

        if(null != serviceReference){
            DictionaryService dictionaryService = (DictionaryService)context.getService(serviceReference);

            System.out.println("check word:" + dictionaryService.check("word"));
            System.out.println("check osgi:" + dictionaryService.check("osgi"));
            System.out.println("check equinox:" + dictionaryService.check("equinox"));
            System.out.println("check eclipse:" + dictionaryService.check("eclipse"));
        }
    }

    public void stop(BundleContext context) throws Exception {
        serviceReference = null;
    }
}

3. Custom 端使用
如果没输出显示，可在console中 update custom 插件。

结果：

4.工程文件下载
demo.dictionary.custom.rar
