JSP vs XSL

We are trying to decide whether to use JSPs or XML/XSL for the user
          interface for our application. It is a large-scale application - large
          online shopping site - and need to do all coding in 6 weeks. One question
          we have is whether it is more expedient ot use JSPs or XSL for the
          presentation. Is one or the other more difficult to pick up, etc.

That depends on your talent pool. Remember that JSP are automatically compiled
          into servlets and can be used to produce XML instead of HTML. This XML can then
          be formatted before being sent to the client.
          JSP are for the most part easier to work with (in terms of compilation and
          deployment, not to mention a bunch of code that gets produced for you
          automatically).
          But, if you have some experienced servlet programmers who never used JSP, I
          would skip the learning curve to meet the deadline(tm).

Jsp & XML-XSL

Hello.
I have a device that produce XML output file( dynamically )
I need to read it by Jsp page.
I able to do it using XSL but when XML changes my Jsp page is not updated.
Only if i recompile jsp page i get new data
Do you know some methods to get dynamically XLM data?
Thx
Riccardo
example code:
<%@page contentType="text/html"%>
<html><head><title>XSLT Example</title>
<%@ taglib uri='/WEB-INF/tlds/xslt.tld' prefix='xslt' %>
</head>
<body>
<xslt:apply xsl='Fieldgate.xsl'>
<%@ include file='output.xml' %>
</xslt:apply>
</body></html>

Thats because you are including your XML in your JSP.
If you were to parse your XML in your in your JSP using SAX or DOM and then use them to populate the dynamic contents of your JSP then you will not need to recomplie your JSP.
Read the following article. It will help you out and possibly give you some other Ideas.

Hi
I think that It's because of some confilict between packages, try to set more priority for your jar files in tomcat.bat file as below :

Deploy JSP, XSQL-XSL Application on OC4J or Apache?

I have an application having JSPs and XSQL-XSL pages (not EJBs)
for the internet.
Which is the best deployment type?
- Running both on OC4J (after installing XSQL),
- Running both on Apache,
- Running one on Apache and other on OC4J?
What about using Apache as a proxy sending requests to OC4J?
Thanks.

I deployed both on Apache (JSP,XSQL) and I have another PC with Apache as Proxy.
It works fine. I dont know the performance when many users try to connect.

XML having a JSP as XSL stylesheet ...

Hi,
In WLS 5.1 SP6, I have a XML which uses as XSL stylesheet a JSP served by WebLogic (<?xml/stylesheet href="style.jsp?order=3"?>
It appears that, when I try to pass more than one parameter to my JSP (i.e. "style.jsp?order=3&value=1"), the XML page does not "recognize" it anymore ... I have to pack all my parameters in a single string, pass it to my JSP and then parse it, which is quite ugly. Has somebody an explanation for this ? Thanks

Perhaps you need to encode the '&' in the stylesheet processing instruction.

JSP and XSL Processor - How do you send the processed file to a JSPWriter?

The hierarchy for the relevant I/O classes is:
Object---OutputStream
Object---Writer---PrintWriter
Object---Writer---JspWriter
For the processed file from the Oracle XSLProcessor, typically HTML, the XSLProcessor API v2.0.2.9 offers either 'OutputStream' or 'PrintWriter' as targets.
Unfortunately, a 'PrintWriter' cannot be used as a 'JspWriter'.
I realise that I can call
HttpServletResponse.getOutputStream()/getWriter() but there may be problems using this with the 'out' object.
According to the JSP documentation: 'Either getOutputStream() or getWriter() may be called to write the body, not both.'
The XSLProcessor API does offer an 'XMLDocumentFragment' as another target so I can make an XML document from this but looking at the API for 'XMLDocument', this again only offers 'OutputStream', 'PrintDriver' or 'PrintWriter' as targets.
Not sure if 'PrintDriver' helps.
How do I send the output from the 'XSLProcessor' to a 'JspWriter'?
Why does the API not offer a 'Writer' as a target?
Polite observation - this would be consistent with the 'OutputStream' being offered and, if changed, would not break any existing code.
null

You can also use a PrintWriter to wrap a JspWriter
since PrintWriter has a constructor that takes any
Writer instance.I'm having the same problem, I've spent a lot of time
on it but I can't get it work.
Could you post some working code that shows how you
can do it?
Thanks.
It works now, I have used the code:
result = processor.processXSL(stylesheet, xml);
PrintWriter pw = new PrintWriter(out);
result.print(pw);
I had tried this before but there was an error in other place that prevented it to work.
Thank you anyway.

What to import in the JSP file??

I want to use jsp and xsl to convert xml to html in order to display the file. But I come across a problem, I don't what should be import into the jsp file. Should I import these? <%@ page import="org.xml.sax.*" %>
<%@ page import="org.apache.xalan.xslt.*" %>
Since I'm not very good at this field, can anybody give me some suggestion to hlep me to work it out?
thanks~

One thing is sure. Whatever the classes you are going to use, need to be imported in your Jsp.
There is no need for different import statements. You can write in a single import statement (comma separated).
So, forget about the import statements and do your coding, finally you can look at the code and decide what classes (packages) you need to import.
I think you need to import
org.xml.sax.*;
org.xml.sax.helpers.*;
import javax.xml.parsers.*;
Hope this helps.

Help whit dinamyc jsp events ^^

Hello:
hummmm! need help in create jsp (xml, xsl, xslt or whatever) whit dinamic html components events like checkbox, i.e:
When i click in a checkbox or radio button, the action (event) must make me generate dinamyc html code like show fields or forms (not hide forms or tables, just generate tables or forms whit the checkbox or radio button actions). But i wan�t use javascript just JSP, XML, XSL or whatever.
Please give me help =P plz

You can use AJAX for doing this. Or you can submit the page onchange event of the combo and get the required values from the DB and set the values in the text field.
Please check the onchange attribute of the select tag.

Xml/html to jsp - problem with quotes in attribute values

I am trying to convert a static html document into a jsp using an xsl stylesheet, but run into problems trying to use the jsp expression syntax inside of attribute values.
Here is a sample of the source file:
<input type="text" name="firstName" value=""/>
Here is what I want the resulting jsp file to look like:
<input type="text" name="firstName" value="<jsp:expression>customer.getField("firstName") </jsp:expression>">
Here is what part of my stylesheet looks like:
<xsl:template match="input">
<xsl:copy>
<xsl:copy-of select="@type"/>
<xsl:copy-of select="@name"/>
<xsl:attribute name="value">
<xsl:text disable-output-escaping="yes"><jsp:expression></xsl:text>
<xsl:text disable-output-escaping="yes">customer.getField(</xsl:text>
<xsl:text disable-output-escaping="yes">"</xsl:text>
<xsl:value-of select="@name"/> ")
<xsl:text disable-output-escaping="yes">")</xsl:text>
<xsl:text disable-output-escaping="yes"></jsp:expression></xsl:text>
</xsl:attribute>
</xsl:copy>
</xsl:template>
The problem i have is with the <%= customer.getField("firstName") %>. I have tried several different ways of inserting the double quotes around firstName, but no matter what I try, it always uses the entity reference instead of actually putting the " character. The jsp container will not accept the entity.
I am assuming that the problem is with trying to place double quotes inside of an attribute value. Any ideas how to get around this?
Thanks
David

Which App Server are you using?
You should just be able to escape the double quotes.
If that doesn't work, it's a bug in the app-server.
Alternatively, you can use single quotes around the
attribute value.
Hope that helps,
AlexSorry, I'm an idiot. By escaping you meant the unicode character escape "\u0022". I had not tried that. However, once i realized what you meant, I tried it, and it worked. Thanks for your help.

Merge all XSL files

I am using XSL/JSP to design the Application Form.
Now I want to split header, sidebar, footer and
app form into 4 XSL files, only app form will receive dynamic data from XML, the rest are static pages.
One way I can think of is using 5 JSPs to process
E.g.
     ApplicationForm.jsp
     ->Header.jsp     -> Header.xsl
     ->sidebar.jsp     -> Sidebar.xsl
     ->Footer.jsp     -> Footer.xsl
     ->Form.jsp     -> Form.xsl
But this method may be very expensive as each JSP has to invokes XSLTProcessor.process()
How can I process these XSL files better in term of performance?
Can I merge all XSL files into one first?
Albert KT Tan

Hello,
I'm not exactly sure I get what you're looking for.
What I was suggesting was one jsp calling a Java Class 5 times and outputting the XML string translated to HTML in their proper places.
You're going to have 5 input xml files, so no matter what you're going to have to do 5 translations, right? If so what's the difference if you pass the same xsl to each translation or 5 different ones? Is this the part I'm confused on?
You could do it like this too.
<%
//The class that does the translations
ApplyXML ax = new ApplyXML();
String header = ax.apply(xmlFilePathHeader, xslFilePathHeader);
String sidebar = ax.apply(xmlFilePathSidebar, xslFilePathSidebar);
String footer = ax.apply(xmlFilePathFooter, xslFilePathFooter);
String form = ax.apply(xmlFilePathForm, xslFilePathForm);
%>

<html>
<body>
<table>
<tr>
<td colspan="2">
<% out.println(header); %>
</td>
</tr>
<tr>
<td>
<% out.println(sidebar); %>
</td>
<td>
<% out.println(form); %>
</td>
</tr>
<tr>
<td>
<% out.println(footer); %>
</td>
</tr>
</table>
</body>
</html>
Am I still misunderstanding?

Problem in IAS Server with generation of PDF with FOP and XML parsing

Dear co.forumers :
We are developing an application that generates a pdf document with FOP Apache utilities, and this PDf is stored in a folder of the server. Firts of all, a DDBB data is retrieved using java ( jdbc) middleware classes ( servlets ), and with these data, the pdf is generated using FOP. In these process, he data retrieved from the DDBB is converted in a XML file , and the with the XSL FOP utility, the pdf is generated.
In the other hand, we have another application that consults data from a java beans, using a JSP, generates a XML with the data of the beans, and with this XML, and with a XSL file generates and html , with the data and fixed text.
Both applications have been deployed as a separated WebApp in the IAS. Both use Xalan as XML parser amb Xerces is used aswell.
So, the problem is , after generating a pdf with the firts application, every html generated via JSP-XML-XSL transformation in the second application is shown completelly bad formated. All fixed text are wrongly composed, and the text that should appear in textFields and ComboBoxes is also bad formated. The XML with the data is well generated, so the problem is in the parsing of these XML and the conversion in html through XSL. We have to re-initiate the server and then everything goes well again. If no pdf is launched, no problem occurs with the other application.
How an a WEB APP pplication can affect to another, installed both in different folders of the IAS ? We tried to change Xalan version and FOP version, but no result.
Is this a Poltergeist ?? and X file , maybe ?
Has anyone had the same problem ?
Pleae, any help will be very wellcomed.

A PDF document may be generated in the JDeveloper OC4J server.

Cannot find file resource

Hi,
this question might seem very trivial and you think that I should find it by searching on the internet but as often: you never find exactly what you want when you really need it.
So, here is my question:
I have a dynamic web project in eclipse and in my jsp a xsl file has to be loaded. I copied the file under the WebContent folder and within my jsp I tried the following:
if(new File("transformation.xsl").exists())
out.println("<h1>exists</h1>");
else
out.println("<h1>file does not exist</h1>");but everytime the file is not found. I dont know how to fix it - of course I tried some path combinations but it did not work.
Thanks for answers in advance!

Do you realize that this will look for the file in the current working directory? There is no absolute thumb rule where exactly it is. You should also never rely on the operating system's or application server's configuration of the working directory. The file system operates completely independent from the web application. If you're interested though, just call File#getPath() to see what its absolute path is after all.
There are two general approaches to access (external) file resources inside a web application, independent of where it is installed.
1) Use ServletContext#getRealPath(). Place the resource somewhere in the webcontent. E.g. in the /WEB-INF. Then pass its path as a relative web path to ServletContext#getRealPath() to convert it to an absolute file system level path. Finally use it in File().
2) Use ClassLoader#getResource(). Place the resource somewhere in the classpath or add its path to the classpath. Then use ClassLoader#getResource() to get its absolute URL. Finally use it in File(). Or just check if it is null or not. If you actually need an InputStream of it after all, then you can also just use ClassLoader#getResourceAsStream().

Good servlet design?

Hi!
I've been using Servlets for a little while now, but I'm not sure if I use them correctly.
I usually write rather small servlets, like reading something from a database, and then putting that data into a table. Then I use the jsp:include tag to include 3-4 servlets in one jsp. I like this approach rather than tag libs in jsp (not quite the same but still..).
Is this a bad way to use servlets?
regards,
Vidar

Opinions on what is a good design are like opinions, everyone has one.
My thoughts are basically have one servlet per page. Have the servlet do all the 'server side' work (database, ejb and other calls). Once done, forward to something that will 'draw' the page (JSP, XML/XSL). This way if you want to change the look, you only change the HTML in the JSP/XSL template.
Basically, pick what works best for you. I would suggest learning the Serlvet/JSP APIs though. Many times I've seen people get totally thrilled over a feature in some other API (STRUTS) that is provided by the Servlet API. Since all Web Servers MUST follow the Servlet API, I would suggest learning it as your code will always work and be very portable.
