Document Retrival from database.

Hi,

I have a requirement of uploading the file like .doc, .xls, .jpeg, .txt, .gif, .pdf into database. so, i uploaded the file by converting them into bytearray and then to database like blob. Up to here it is fine. My problem is view the file. i.e. i know the file extension and i will get the byteArray from the database to the presentation layer. I need a logic such that i can use this byteArray and file extension to show the file like for example, if i upload a image, it converts to bytearray and then to blob to database. then i retrieves the bytearray from the database and i have to convert this byte array to image. similarly to .doc, .xls, .jpeg, .txt, .gif, .pdf.

Thanks in Advance.

calling the funciton name

Thanks,

But here my scenario is different, when i use method.invoke() function it returns an object, which i don't want this. My function returns a list of classes. So, when i use method.invoke() function, i need to typecast the list of the classes. but i will get the class name dynamically, so how to use this for a generic way.

Let me narrate you.

I will send a classname as parameter to a fucntion. that function will gets the fields name, in that fields having any list type fields, I have to traverse in to that list. So for traversing i used the getter of that list and i invoked that function it returns object. but i need to typecast the list of the classes. but i will get the class name dynamically, so how to use this for a generic way.

Problem with Simple Facelet

1. Create a layout.jspx page by including following code.

<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0"
xmlns:ui="http://java.sun.com/jsf/facelets">

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<link href="default.css" rel="stylesheet" type="text/css" />
<link href="cssLayout.css" rel="stylesheet" type="text/css" />
<title>Facelets Template</title>
</head>

<body>

<div id="top">
<ui:insert name="top">Header</ui:insert>
</div>

<div id="content">
<ui:insert name="content">Content</ui:insert>
</div>

<div id="bottom">
<ui:insert name="bottom">Footer</ui:insert>
</div>

</body>
</html>

</jsp:root>

2. Create a new JSP Page and add the following taglibraries in addition to existing core and html tag libraries.

<jsp:root xmlns:ice= “http://www.icesoft.com/icefaces/component”
xmlns:ui= “http://java.sun.com/jsf/facelets” >
</jsp:root>

3. Use the above layout file in JSP Page using <ui:composition> component.

<ui:composition template=layout.jspx"></ui:composition>

4. Change the content part of main page using <ui:define> component. Place this component inside <ui:composition>.

<ui:composition template="layout.jspx">
<ui:define name="content">
<f:view>
<ice:form>
<ice:outputText value=”welcome to Facelets”/>
</ice:form>
</f:view>
</ui:define>
</ui:composition>

5. Include following code in faces-config.xml

<application>
<view-handler>
com.icesoft.faces.facelets.D2DFaceletViewHandler
</view-handler>
</application>

6. Add Dependency for following jars
1. el-ri.jar
2. el-api.jar

regarding request and session scope's

i was using icefaces, i created a login page which redirect to success and failure on user input, i used the bean scope to 'request', the problem i am facing is .....
i have given the correct information to login so it redirected to success page in that i am printing the username, its fine and again i redirected to another page to check the username is carried or not, the page contains only the username related stuff
<ice ':'outputText value=#{loginDataBean.uname}/>
this has to throw an error because i have given the managed bean scope is request but it is showing the username, not throwing any exception. But how this is coming for the second page, even i gave the scope to request...... i am using the net beans ide and IE7. so please resolve this issue.

and the same thing i tried for session, application, page ..............same output is coming ....................................
