dwr

Eclipse is showing the following errors in my Spring's applicationContext.xml : cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'dwr:configuration'. myappservlet-servlet.xml MyApp/src/main/webapp/WEB-INF line 23 XML Problem cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'dwr:controller'. myappservlet-servlet.xml MyApp/src/main/webapp/WEB-INF line 21 XML Problem cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'dwr:remote'. myappservlet

I am using Spring with DWR . I want to return a file object as response , however I save the file (to be sent) at server temporary location and then send its location as href for anchor tag on client side , however I wonder if there could be a way to throw the file directly to browser on response object without saving it temporarily on server. I expected if there could be a way to send file as a response via DWR. public ModelAndView writeFileContentInResponse(HttpServletRequest request, HttpServletResponse response) throws IOException { FileInputStream inputStream = new FileInputStream(

参考博客： https://blog.csdn.net/Marksinoberg/article/details/55505423 下载Dwr.jar文件 到官网 http://directwebremoting.org/dwr/index.html 。下载这个jar即可。 下载commons-logging.jar 官网上清晰的说明了dwr工作的时候需要依赖于commons-logging，所以还需要下载一下这个jar包。下载地址： http://commons.apache.org/proper/commons-logging/download_logging.cgi 项目目录 把上面下载好的jar包放到刚才创建的项目的WebContent/lib目录下。 依照dwr的功能：浏览器可以调用服务器端的java方法。 那么我们不难理解，项目中有自己写的java方法，有一个jsp页面。然后项目本身添加一些配置（具体是web.xml和dwr.xml）。最后完整的项目目录就是这样了。 web.xml l 官网上示例 <servlet> <display-name>DWR Servlet</display-name> <servlet-name>dwr-invoker</servlet-name> <servlet-class>org.directwebremoting.servlet

This question already has an answer here: How do servlets work? Instantiation, sessions, shared variables and multithreading 8 answers So far I understand Httpsession concepts in Java. HttpSession ses = req.getSession(true); will create a session object, according to the request. setAttribute("String", object); will, bind the 'String', and value with the Session object. getAttribute("String"); will return an object associated with the string, specified. What I am not able to understand is: I am creating a session object like HttpSession ses = req.getSession(true); and setting a name for it by

In Java, we work a lot with JAXB2. Object<->XML mappings are defined as annotations in Java classes: @XmlRootElement(name="usertask", namespace="urn:test") public class UserTask { @XmlElement(namespace="urn:test") public String getAssignee() { ... } public void setAssignee(String assignee) { ... } } JAXB runtime can read these annotations and create unmarshaller to parse XML into an object instance or marshall an object into XML. JAXB ships a schema compiler (XJC) which can generate annotated classes out of XML Schemas, which is another great feature. Lately we've been working a lot with
