ajax - Display code flow on UI in java web application -

i have java web application, developed in spring framework. in that, running job (like moving data 1 database other database).

i want track progress of operation, not displaying progress bar, instead of that, want display real time logs, track flow, on ui.

i using reverse ajax using dwr seems, excessive use of it, creating outofmemory error.

how can achieve it?

web.xml code

<servlet>         <servlet-name>dwr</servlet-name>         <servlet-class>org.directwebremoting.spring.dwrspringservlet</servlet-class>         <init-param>             <param-name>debug</param-name>             <param-value>true</param-value>         </init-param>         <init-param>             <param-name>activereverseajaxenabled</param-name>             <param-value>true</param-value>         </init-param>     </servlet>      <servlet-mapping>         <servlet-name>dwr</servlet-name>         <url-pattern>/dwr/*</url-pattern>     </servlet-mapping> 

ajax file code

@remotemethod     public void movedata() {         string currentpage = webcontextfactory.get().getcurrentpage();          browser.withpage(currentpage, new runnable() {             public void run() {                 try {                     databaseutility.movedb();                 } catch (exception e) {                     // todo auto-generated catch block                     e.printstacktrace();                 }              }         });
