After working extensively with .Net and Java, these are the differences I
see:
Java does not have Reflection.Emit
But it does have Reflection.

well some thing is not right i think
i tried this query
recordSet = query.executeQuery("SELECT * FROM members WHERE Name LIKE
'Ali*'");

I am using the javax communication API to talk to RS232. Now this
works fine by using the serialPortEventListener but I always wait for
500 ms to read/write new data. I have made my classes Runnable to put
them into threads and use synchronized to let one thread finish

   I'm creating a newsreader object for use in the global area of a
servlet, so it can be used by multiple threads. I only want a single socket
connection for all threads. For example, a thread would need to talk to the
socket exclusively through several readLine() and printLn() ...

Hello ppl.
I've been trying to use jTDS instead of Sun's JDBC-ODBC bridge in our web
application.
I'm running into a couple of issues:

Isn't there any JSP formatter out there (basiclly it's sufficient if it
does indent HTML tags, aligns tag attributes and leave Java code as it is)?

when people say server-side development, that means develop
applications running on server? for example, ASP.NET, J2EE such as JSP,
EJB development? correct?

I've a (beginner) problem accessing a method on another class.
When I execute a method such as:
//response to a swing button
public void actionPerformed(ActionEvent event) {

I know that forEach is not allowed with JSF. At the moment I'm trying to
 develop a renderer with its own iteration, as suggested in paragraph
9.2.8 of the JSF 1.1 specs (I wouldn't really like to use dataTable), so
that I can have the same functionalities of the JSTL forEach. ...

The standard dialog boxes in swing seem to be called JOptionPanes and they
seem to want a frame variable, which looks like it ought to be the parent
frame (the main frame of the applet in question), and I don't see an
obvious way to get at that in an Eclipse application which uses ...

Thought HttpRequest would have something like getUserRoles() or
something, but no go.  What gives w/ the Javax API?  Why no
getUsesrRoles()?  What am I missing?  How do I get a list of roles that
an authenticated user (Principal, whatever) has access to?

Using JDBC , what would be a more elegant way of determining  whether or
not a record already exists in a DB table  before inserting it?
