How To Do Pagination Similar in Google?

Suppose you've got 1000 records in a requestScope list or map called data:
<display:table name="data" scope="request" id="record">
<display:column title="Title 1" property="property1"/>
</display:table>


and so on... There's a manual also. And you can provide the size of the page, the styles, an url to lin on each column. You can render a column by yourself or make it to autolink if the column is an url or emailaddress...



Check the examples, they tell you how to do the whole thing. Also I'll cut'n' paste here a real code of my own for you to see. It's embeded in a struts based application. See the pagesize and requestURI wich will help you do the paging. The requestURI should store the data in an attribute called "listaContactos" in scope session. I just store the data when a search is requested, the pagination is done by the displaytag so if the user don't changes the search criteria the list is the same as in the previous page but just shows up the next 10 records... hope to have explained, sorry my bad english:


<<
<display:table sort="list" name="listaContactos"
scope="session" id="contacto"
requestURI="/secret/gestion/buscarContactos/view.do" pagesize="10"
align="center" width="400px">
<display:setProperty name="basic.msg.empty_list">
<p align="center">
No hay resultados para la búsqueda.
</p>
</display:setProperty>
<display:column title="Nombre"
sortable="true"
url="/secret/gestion/editarContacto.do?accion=editar"
paramId="key"
paramProperty="contactoId">
<bean:write name="contacto"
property="apellido1"/>&nbsp;<bean:write name="contacto"
property="apellido2"/>, <bean:write name="contacto"
property="nombre"/>
</display:column>
<logic:match name="buscarContactosForm"
property="contactoEmpresa" value="true">
<display:column title="Cargo"
property="cargo"
sortable="true"
url="/secret/gestion/editarContacto.do?accion=editar"
paramId="key"
paramProperty="contactoId"
group="15"/>
<display:column title="Empresa"
property="nombreEmpresa"
sortable="true"
url="/secret/gestion/editarEmpresa.do?accion=editar"
paramId="key"
paramProperty="empresaId"
group="15"/>
</logic:match>
<display:column title="Tel&eacute;fono"
property="tlf1" width="60px"/>
</display:table>

WebSphere MQ Interview Questions

What is MQ and what does it do? Ans. MQ stands for MESSAGE QUEUEING. WebSphere MQ allows application programs to use message queuing to participate in message-driven processing. Application programs can communicate across different platforms by using the appropriate message queuing software products. What is Message driven process? Ans . When messages arrive on a queue, they can automatically start an application using triggering. If necessary, the applications can be stopped when the message (or messages) have been processed. What are advantages of the MQ? Ans. 1. Integration. 2. Asynchrony 3. Assured Delivery 4. Scalability. How does it support the Integration? Ans. Because the MQ is independent of the Operating System you use i.e. it may be Windows, Solaris,AIX.It is independent of the protocol (i.e. TCP/IP, LU6.2, SNA, NetBIOS, UDP).It is not required that both the sender and receiver should be running on the same platform What is Asynchrony? Ans. With messag...

Java Garbage Collection

Explain Garbage collection mechanism in Java? Garbage collection is one of the most important features of Java. The purpose of garbage collection is to identify and discard objects that are no longer needed by a program so that their resources can be reclaimed and reused. A Java object is subject to garbage collection when it becomes unreachable to the program in which it is used. Garbage collection is also called automatic memory management as JVM automatically removes the unused variables/objects (value is null) from the memory. Every class inherits finalize() method from java.lang.Object, the finalize() method is called by garbage collector when it determines no more references to the object exists. In Java, it is good idea to explicitly assign null into a variable when no more in use. In Java on calling System.gc() and Runtime.gc(), JVM tries to recycle the unused objects, but there is no guarantee when all the objects will garbage collected. Garbage collection is an automatic pro...
