How to best apply Spring, Spring MVC and Hibernate frameworks
I'm an individual programmer, developer and (in the corporate world, Only) I see a huge demand for the frameworks: Spring, Spring MVC, webflow, and Hibernate. Popular today: Spring MVC, webflow, GWT.

I've been going through the tutorials, and the technology looks awesome ! What I would like to know, is.. How can I apply these frameworks in building websites ?

I can't imaging doing any kind of serious website building without a modern CMS or Portal layout (whether in Java/php-opensource), And yes, MVC gives you the validation and authentication hooks to be used.

All the demo's on Spring, cover some elementary, contrived example.
If I learn these technologies (and I'm well on my way), how do I put them into practice, and in what context (no pun intented) do I use them ? I don't want to rebuild a CMS system. Maybe these are meant to be used in a Portal structured system.

No. I never solved it.

Maybe you can register with an official signing company but you have to pay a fee to get that service.

serverside Java applet support check?

Sat, 06 Mar 2010 00:35:50 -0700

Is there a way to check Java applet support on the server?

I noticed google analytics having a place listing how many visitors had Java applet support and wonder how they might do that check. I'd like to serve different content based on knowing if the client's browser supports Java.

I know the client could check it by having a small Java applet that sends a signal indicating support when it loads but I want to avoid slowing computers down just to make this test and I'd prefer putting everything on the server end.

Re: no pageEncoding

Thu, 03 Dec 2009 23:27:19 -0700

pageEncoding：The encoding used for the JSP page file, as well as
the response charset if no charset is specified by contentType.

If this attribute is omitted, but a charset is specified for contentType,
that charset is also used of the page; if contentType doesn't specify a charset, ISO-8859-1 is used for a regular JSP page, and UTF-8 is used for a JSP Document.

you can use response.setCharaterEncoding() to set the charset for jsp

hope it helps

Does a Portlet JSP get complied into a servlet?

Thu, 03 Sep 2009 19:52:55 -0700

Hi

I am using the IBM JSP Server Portlet. I have a content management system that allows a content editor to change HTML content in the JSP. The updated JSP file is then deployed to a Network File System that is essentially mounted to the Portal Application server where the JSP Server portlet is installed. My question is, Does a portlet JSP get complied into a servlet every time a new version of that JSP is deployed with it's content changed?

Thank you

Hi,
I am trying to view all records in a Database through an html page called via a servlet. However the page returns the first row(record) only. I keep getting the following error in Apache Tomcat console window:
java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Invalid Descriptor Index

below is a code snippet from my servlet

Statement myStatement = databaseConnection.createStatement();  ResultSet results = myStatement.executeQuery("SELECT * FROM Classmates");

out.println("<TABLE BORDER=2, HSPACE=7>");
out.println("<TH>Name<TH>Address<TH>Town<TH>County<

out.println("<TR>");

Need help on shopping cart javaBean code*

Tue, 28 Jul 2009 17:31:23 -0700

Compiling the following code outputs the error that the javaBean curItem does not exist. However, my other code depends on a javaBean curItem. I don't understand why I cannot update the quantity property of a specific object (curItem) in the arrayList lineitems if I am declaring curItem to be an object inside lineitems using the var attribute. Please clarify and perhaps help update the quantity property in an object in lineitems using a curItem javabean. Thanks!
