[ANN] JOT Servlets web component framework - version 3.0
JOT Object Technologies has released version 3.0 of the JOT Servlets Java web components framework. Jot Servlets use Java objects (Java Beans and POJO's - plain old java objects) to render dynamic content into standard HTML web pages. http://www.jotobjects.com JOT Servlets Framework: JOT Web Components are dynamic content building blocks for rendering composite views, portals and tiled layouts. Iterator components render tabular output using Java Collections and database queries. JOT Web Components can be combined with unlimited nesting depth. JOT Views is a dynamic content rendering engine for Java Servlets and JSP. JOT JSP Tags are custom tags for rendering dynamic content web components. === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: Problem with Struts FormFile object.
Create a javax.activation.MimetypesFileTypeMap object and add your types to that object. Then call javax.activation.MimetypesFileTypeMap.getContentType(yourFileName) to get the contentType for the file on the server without relying on the browser content type setting. MimetypesFileTypeMap will return application/octet-stream as the default if it does not know the content type. You have to include the J2EE activation.jar in your classpath for this to work. Here is the API doc - http://java.sun.com/javaee/5/docs/api/javax/activation/MimetypesFileTypeMap.html Paul Copeland http://www.jotobjects.com JOT Servlets dynamic web component framework Date:Fri, 28 Apr 2006 10:09:54 +0530 From:Abhijeet Kahale <[EMAIL PROTECTED]> Subject: Problem with Struts FormFile object. Hi, I am facing some problems while uploading a file using Struts' FormFile object. I want to allow user to upload only .xls/.tdt/.txt files. For that I am comparing the ContentType of the file being uploaded using FormFile's getContentType() method. The problem is, when I upload .xls files, it properly returns a string as 'application/vnd.ms-excel' so that i can compare it with constant and proceed further. But when I upload .tdt or .txt files, it returns a string 'application/octet-stream' instead of 'text/plain', So when i compare it with the constant(which is set to "text/plain"), test fails even if user ha= s uploaded proper file with proper contents. Moreover, this only happens on my machine, If I test it on some-one else' machine(one of my colleague), it works fine. So, my question is, is there some setting in my browser that is making the formfile object to send wrong mime type or this is really a problem? And if it is related to browser setting, what setting should I change? also, if user also has that setting in his browser, how should I handle it? please reply ASAP... thanks in advance, Abhijeet. === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: JSP-INTEREST Digest - 1 Mar 2006 to 17 Mar 2006 (#2006-8)
It is really hard to get this kind of design to work correctly. The response will come back to the frame that submitted the request to the jsp page (servlet). You could try returning a 204 status code (no change) to the first frame and then run some javascript to tell the second frame to update itself with window.location.replace or reload.

unless the JspException contains a root cause, in which case its root

Which version of the sources did you look at?
The Tomcat 5 version of JspServletWrapper.service(), which I attached,
has this code at the bottom:
} catch (ServletException ex) {
throw ex;
} catch (IOException ex) {
throw ex;
} catch (IllegalStateException ex) {
throw ex;
} catch (Exception ex) {
throw new JasperException(ex);
}
which wraps an exception inside a JasperException only if it is
neither of type ServletException, IOException, and
IllegalStateException.

Re: Window pop-up problem!....
Well a bit off topic for servlets - But anyway you can open another browser window with the "target" attribute on the HTML "a href=" and "form" tags and then play games with the focus javascript events on the two windows. The window.open() javascript method also opens another browser window. DHTML layers are probably a better design for human usability. None of this is truly modal in the stateless web client world. The amount of time you will invest in trying to get this half way working may not be worth it in the end. - Paul Copeland - JOT Servlets - http://www.jotobjects.com Date:Thu, 29 Jul 2004 09:37:23 +0530 From:Manish Malhotra <[EMAIL PROTECTED]> Subject: Window pop-up problem!

Please help. I have just been assigned to build a simple and small portal site in JSP. I am rather new to JSP. (I do know how to code C, C++, C#, VB, VB.NET, ASP.NET, ASP, HTML, XML, XSL, and also know a little Java). I am familiar with 3-tier architecture, the RUP, MVC, OOA, OOD, and OOP principles. I want to use the MVC design pattern for this JSP site. What I don't know is whether or not I should use "struts" framework or roll my own container. From the looks of things, it might be a bit more than I need and, since I am new to JSP, it might be a bit too ambitions. I would like to do something "like" struts, but something kind of smaller implementation, less complex. I am looking for a simple architecture. (Note-- I am reading and studying a lot, but I want to get the "industry perspective" from veteran JSP programmers.) (Note-- The site will be JSP running on JRun in Windows NT/IIS5, will be less than 100 pages, will be driven by SQLServer or Oracle, will have about a total of support about 100 casual users, and will be an intranet site.) And so, I ask... What do you think? What do you suggest? Any help at all is appreciated (including outright directions, links, and reading suggestions).

Re: Off-topic: JSP and MySQL
Your example with multiple "begins" indicates a desire to have nested
transactions. AFAIK, SQL does not support that and JDBC drivers will
throw exceptions if you try it. Some database engines support
"savepoints" or "checkpoints" providing a roughly equivalent functionality.
Your last statement that "it solves only mistakes durring queries" is
incorrect. A single rollback statement will undo all the updates back
to the beginning of the transaction. Experiment with a database that
supports Transactions and this will become clear.

Is it ok then performance wise to iterate over the vector and display the items in the jsp page? For example, a method in a javabean executes a jdbc statement that returns some recordsets. These recordsets are added to a Vector and the Vector is returned by the method. In my jsp page I get the Vector with recordsets from the bean method. Then I iterate over the Vector to display its items in a html table. Is this a good way of doing things? If not can anyone suggest a better way? The methods in Vector are synchronized, so a List or an array is a slightly more efficient approach. But I would suggest that you look at JSTL instead. It's action exposes the query result as a type called a Result. From a Result, you can get an array of arrays where the first dimension represents rows and the second the column value, or as an array of Maps where each Map represents a row, with keys matching column names. Even if you access the database in servlet code (for instance), you can use utility methods to convert a JDBC ResultSet to a JSTL Result.

Just for kicks, here is the JOT (http://www.jotobjects.com) version of
the example from Hans' article. The EachDay bean would be roughly
similar to the ForEachDayTag class in the article, with methods getNext,
getIsSunday, and getFormatDate (you don't have to know anything about
custom tags, JSTL, or EL syntax to implement this version).
JOT.Repeat(JOT.EachDay.Next)
JOT.If(JOT.EachDay.isSunday())
JOT.Else

JOT.EachDay.formatDate("EE dd, MMM ")

Hans,
I just read the article which is very interesting for people that want
to use libraries to develop JSTL style tags.
In reading the article, I realized that I had a nagging question
about JSTL, tag libraries, etc vs JSP.
Before I answer, let's just clarify what "JSTL vs JSP" means. JSTL is
defined as a tag library that can be implemented (by anyone, but
typically by container implementors) using the standard JSP API for
custom tag libraries. So there's really no "JSTL vs JSP"; using JSTL
_is_ using JSP, just as using the standard , scriptlets,
etc. means using JSP.
The only difference between JSTL and any other tag library is that JSTL
is defined by a spec, and therefore more likely to be supported by all
containers (eventually) without having to install it. This also means
that a container vendor can choice to support it by generating highly
optimized code when converting a JSP page to a servlet, e.g. generate
a regular Java if statement instead of calls to the tag handler for
.
With this in mind, I therefore assume that you really wonder about
"using custom tag libraries, such as JSTL, vs using Java code in
scriptlets" based on your comments below. That's a fair question (even
though it's been asked and answered many times on this list and
elsewhere ;-)
To quote from your article some code:
">
Is JSTL clearly easier than JSP? I'll admit that I'm biased. As
someone who know Java this looks more complicated than doing the
same or similar things with JSP. But rather than use anecdotal
evidence one way or another I'd be intrested in more systematic
research on this.
The best way I can answer this question is to show how this
example can be written with Java code in scriptlets instead:
<%
Calendar calendar = new GregorianCalendar();
calendar.set(Calendar.DAY_OF_MONTH, 1);
int lastDay = calendar.getActualMaximum(Calendar.DAY_OF_MONTH);
int thisMonth = calendar.get(Calendar.MONTH);
int currMonth = thisMonth;
int currDay = calendar.get(Calendar.DAY_OF_MONTH);
SimpleDateFormat dateFormat = new SimpleDateFormat("EE dd, MM yyy");
%>
<%
while (currMonth == thisMonth && currDay <= lastDay) {
String bg = "white";
if (calendar.get(Calendar.DAY_OF_WEEK) == Calendar.SUNDAY) {
bg = "red";
}
%>
<%= dateFormat.format(calendar.getTime()) %>
<%
calendar.set(Calendar.DAY_OF_MONTH,
calendar.get(Calendar.DAY_OF_MONTH) + 1);
currMonth = calendar.get(Calendar.MONTH);
currDay = calendar.get(Calendar.DAY_OF_MONTH);
}
%>
Which version looks looks easier to you? The, of course, answer
depends on your background. In both versions, it's clearly
"programming"; the primary difference is syntax, but there are also
a few other important differences:
1) Code size
The scripting version is double the size of the JSTL version
(30 lines vs 14 lines)
2) Knowledge requirements
For the scripting version I need to know about the Calendar and
how to set and get its values, and the SimpleDateFormat class.
For the JSTL version, I need to know about the custom tags,
their attributes, and the properties of the exposed data I can
access using the EL.
3) Syntax error handling
With the scripting version, if I make a syntax error, I get cryptic
javac error messages (e.g. "'catch' without 'try'") with line
numbers that refer to the generated servlet source code.
With the JSTL version, I (mostly) get error messages that identify
the custom action and attribute names with line numbers that refer
to the JSP page source.
4) Development tools
If I put the Java code (custom actions, beans) in standard class
files, I can develop the code with a regular Java IDE or syntax
aware text editor (e.g. emacs), and debug it using st
Re: Question on documentation...
Hans - below you say: "/servlet" default mapping has _never_ been in the spec But the Servlets 2.1a Spec (November 1998) has the following under "Servlet Mapping Techniques" - - quote - You can map a servlet by using the special URL /servlet/servlet_name. For example, if you create a servlet with the name listattributes, you can access the servlet by using the URL /servlet/listattributes. You can invoke a servlet by its class name. For example, if a servlet engine receives a request from the URL /servlet/com.foo.servlet.MailServlet, the servlet engine can load the class com.foo.servlet.MailServlet, instantiate it, cast the instance to a servlet, and then let the servlet handle the request. - end quote - So that much was in the spec in 2.1, but it looks like it changed in 2.2, or am I misunderstanding your comment?
