RE: How to create on-the-fly javascript code?
I would make it part of a custom tag. This will also avoid the
copy/paste of javascript in all the jsps.

Subject: How to create on-the-fly javascript code?
Hello,
I want to write something like this in a jsp file
script language=javascript
function f() {
return bean:write name=some_bean property=a_property/;
}
/script
but the bean:write tag isn't processed. So how can I make it processed?
Thank you.

RE: To Whom it may concern
I have seen code in open source projects like Commons Chain which does not use some of the good design principles like command-query separation. Are decisions like these made without any justifications? If yes, then it needs to be documented. It is overwhelming to someone who is new to open source development to do the documentation. Looks like this requires lot of search in the email archives. Any thoughts on this?

I'm happy that you've decided to volunteer your time. I would say your best bet is to decide on what you'd like to do. This should be something that interests you, which, typically, would be something you are having to do at work for work, but that's not always the case. If you aren't sure where you want to help out, a good place to start would be to help out with documentation. This is often the area that is lacking in *many* open source projects. Of if you want write some code and not docs, you could add to or improve the projects test coverage. There are many ways to help. No need to send a resume.

RE: core struts -- best practise fundementals
The tag library allows reuse whereas scriptlets lead to copy/paste oriented programming ;-). Separation of concerns is one of the main principles of OOAD. It allows you to change the logic and presentation layer objects independent of each other. It is easier to develop, maintain and extend a system that conforms to this principle. Bala -Original Message- From: peru cheppanu [mailto:[EMAIL PROTECTED] Sent: Monday, August 29, 2005 12:42 PM To: user@struts.apache.org Subject: core struts -- best practise fundementals Hi all, I am trying to understand the motivation behind seperation of logic and presentation in struts framework. I was wondering if any of you can provide some light if I am thinking in right direction. Now, if you write scriptlets in JSP, that is a bad practice.., however if you hide that functionality in a tag class and implement that tag like struts tags or any other tags.. thats a good practice. For example, I want to send a concatenated string instead of a hashmap to display as per key-value relationship. I meant send [EMAIL PROTECTED] string rather than a hashmap and want to parse it for display. If I write a scriptlet that I use to substring and display only that user is concerned with -- that is bad practice. If I use a tag lib that looks more like logic:substring name=hashArr digits=4, -- good. Am I getting this whole thing wrong?

RE: [OT] How to load a csv file into java
Parsing CSV files in 5 minutes or less!
CsvJdbc - a JDBC driver for CSV files Rocks!
I was looking for an utility which can read and parse the CSV files. The
open source utility CsvJdbc was perfect for my requirements. It parses
the given CSV file with no problem. Just include the csvjdbc.jar in the
classpath and start using the API. The command line argument is C:\\test
(Java requires the escape character \ for the \, which is the
separator). The filename is anything.csv and is stored in the directory
specified above. Version is Version 0.10.
The documentation says :
The driver also now supports scrollable result sets.
This following example code shows how these are used.
...
Connection conn = Drivermanager.getConnection(jdbc:relique:csv: +
args[0],props)
Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,
0);
ResultSet results = stmt.executeQuery(SELECT ID,NAME FROM sample);
resulst.next();
...
results.first();
...
results.previous();
...
results.relative(2);
...
results.absolute(2);
...
But it looks like it is not implemented yet. I got : Oops-
java.lang.UnsupportedOperationException: ResultSet.relative()
unsupported error message.
Here is the modified example program that I am using for my purposes:
/*
* Created on Dec 16, 2004
* @author BXParanj
*/
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
public class RegistrationParser {
private String userName;
private String password;
public RegistrationParser(String fileName) {
}
public static void main(String[] args) {
String index = fcgp001;
try
{
// load the driver into memory
Class.forName(org.relique.jdbc.csv.CsvDriver);
// create a connection. The first command line parameter is assumed to
// be the directory in which the .csv files are held
Connection conn = DriverManager.getConnection(jdbc:relique:csv: +
args[0] );
// create a Statement object to execute the query with
Statement stmt = conn.createStatement();
// Select the EBK_USERNAME and EBK_PASSWORD columns from lead.csv file
String sqlQuery = SELECT EBK_USERNAME, EBK_PASSWORD FROM lead WHERE
EBK_USERNAME = + index ;
ResultSet results = stmt.executeQuery(sqlQuery);
// dump out the results
while (results.next())
{
System.out.println(EBK_USERNAME= + results.getString(EBK_USERNAME)
+ EBK_PASSWORD= + results.getString(EBK_PASSWORD));
}
// clean up
results.close();
stmt.close();
conn.close();
}
catch(Exception e)
{
System.out.println(Oops- + e);
}
}
}

RE: Struts weaknesses question
Developers who are really busy don't have time to give a fancy name to something that already has a name.

RE: Why interface
Program to an interface, not an implementation. This concept is different from deciding whether to use Java Interfaces or abstract classes. The term interface in this context actually means type. This is basically the same thing as the Liskov's Substitution Principle. LSP is a well defined principle whereas the above phrase is vague and leads to confusion among new developers. The interview with Erich Gamma on Artima website clarifies this confusion. So, the term interface could refer to all the public methods in an abstract class or it could be an interface. This guideline implies that when you write code, the variable that you declare will be of appropriate type. If it is too far up the hierarchy you have to cast in order to use methods that are defined somewhere lower down in the hierarchy.
