Use jsp to read xml file

Gents,
I'm a XML & JSP newbie and try to do the following: I have a xml file which can be opened with a browser so that I can see data (let's say my cd collection). Further I have a xls file which makes the display a little nicer, with colors and so. Now, I want to have a jsp page read this xml file and I'm not very succesfull, while I spent hours and hours on Google, but nothing.
What I did so far, was:
- download & install Tomcat 5.5
- make a dir under webapps\mycdcollection
- copy my xml files to webapps\mycdcollection
- make a dir webapps\mycdcollection\WEB-INF
- make a dir webapps\mycdcollection\WEB-INF\lib
- copy standard.jar & jstl.jar to BOTH webapps\mycdcollection\WEB-INF\lib as webapps\ROOT\WEB-INF\lib
Here are my questions:
- How should my web.xml in webapps\mycdcollection\WEB-INF look like?
- Should I precompile my jsp? If so, should there be a classes directory somehwere? How should I make my app know that there is a classes directory?
I'm sure I will have lots more of questions, but if you can get me on the way I'd be very thankful.

hi,
u can interact with xml while in jsp. we have jstl (xml) tags to interact with the xml files.
use the jstl and copy the jar files neede for the jstl in to ur web app folder. u need to copy jstl.jar, standard.jar, jaxen.jar, and optionally (saxpath.jar and xalan.jar) based on the versions of the jstl ur using.
mail me at [email protected], if u have any problems.
Here, are some urls' go through with this,

HO w to use SAX parser to create an XML file on the fly

Hi All,
Currently I am using the DOM parser to create an XML file from a text file. But as the DOM takes much memory and inefficient, I need to convert the DOM translator to SAX translator. Can I do that ?? If YES then how to go about that and if NO then what may be the workaround for that.
Please help me out
Thanx in advance
kaushik

Incidentally, look at this thread:
http://forum.java.sun.com/thread.jsp?forum=34&thread=252415
It has an example of how to transform an XML file via XSLT. If you change this to use the zero-argument form of newTransformer, it will apply the "identity transformation" to your input, thus outputting your XML in valid form. Now you just need to figure out how to provide SAX input to this, and the JAXP download includes an example of that.

Changing the directory Structure of Jsp and web.xml files

Hi,
I am using the JDeveloper 11g preview. Can any one tell me how to change the Jsp and web.xml files ( not in WEB-INF directory of the application) to another directory.
Thanks in Advance
Gopal

Hi Frank,
Is it possible for me to change the folder structure which JDeveloper is providing for web project?
By default JDeveloper is giving the following folder structure.
In the project's root folder there is a public_html and src folder along with .jpr file.
In public_html folder thre is an WEB-INF folder and a jsp file
In WEB-INF folder there is an classes folder along with web.xml file.
I need to have the following folder structure :
The WEB-INF folder should be in root folder of project not in public_html folder
src folder must be in WEB-INF folder.
Thanks in Advance

Need help Take out the null values from the ResultSet and Create a XML file

hi,
I wrote something which connects to Database and gets the ResultSet. From that ResultSet I am creating
a XML file. IN my program these are the main two classes Frame1 and ResultSetToXML. ResultSetToXML which
takes ResultSet & Boolean value in its constructor. I am passing the ResultSet and Boolean value
from Frame1 class. I am passing the boolean value to get the null values from the ResultSet and then add those
null values to XML File. When i run the program it works alright and adds the null and not null values to
the file. But when i pass the boolean value to take out the null values it would not take it out and adds
the null and not null values.
Please look at the code i am posing. I am showing step by step where its not adding the null values.
Any help is always appreciated.

How do I access my encrypted User Account files from my Back Up hard drive? Time Machine was used to create the back up disk; File Vault was used to encrypt the files.

How do I access my encrypted User Account files from my Back Up hard drive? Time Machine was used to create the back up disk; File Vault was used to encrypt the files.

Thanks. I will try going through TM. Since my Simpletech is on the way out, I'll be plugging in a new external hard drive (other than the back-up drive) and trying to restore the library to the new drive. Any advice or warning if this is NOT the right thing to do?
Meanwhile, that is a great tip to do an alternate back-up using a different means. It's been tough to figure out how to "preserve access" to digital images and files for posterity, knowing the hardware will always fail/obsolesce sooner or later, and that "clouds" are only as good as their consistent and reliable accessibility. Upping the odds with redundancy will help dull the edge of my "access anxiety", though logically, it can never relieve it. Will look into

FileOutputStream fos = new FileOutPutStream(C://files/sample.xml);
now , how i will write the xmlString into sample.xml file...
Any suggestions/ ideas/ tutorial links would be deeply appreciated.. thx!

SAX: How to create new XML file using SAX parser

Hi,
Please anybody help me to create a XML file using the Packages in the 5.0 pack of java. I have successfully created it reading the tag names and values from database using DOM but can i do this using SAX.
I am successful to read XML using SAX, now i want to create new XML file for some tags and its values using SAX.
How can i do this ?
Sachin Kulkarni

SAX is a parser, not a generator.Well,
you can use it to create an XML file too. And it will take care of proper encoding, thus being much superior to a normal textwriter:
See the following code snippet (out is a OutputStream):
PrintWriter pw = new PrintWriter(out);
      StreamResult streamResult = new StreamResult(pw);
      SAXTransformerFactory tf = (SAXTransformerFactory) TransformerFactory.newInstance();
      //      SAX2.0 ContentHandler.
      TransformerHandler hd = tf.newTransformerHandler();
      Transformer serializer = hd.getTransformer();
      serializer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");//
      serializer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"pdfBookmarks.xsd");
      serializer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"http://schema.inplus.de/pdf/1.0");
      serializer.setOutputProperty(OutputKeys.METHOD,"xml");
      serializer.setOutputProperty(OutputKeys.INDENT, "yes");
      hd.setResult(streamResult);
      hd.startDocument();
      //Get a processing instruction
      hd.processingInstruction("xml-stylesheet","type=\"text/xsl\" href=\"mystyle.xsl\"");
      AttributesImpl atts = new AttributesImpl();
      atts.addAttribute("", "", "someattribute", "CDATA", "test");
      atts.addAttribute("", "", "moreattributes", "CDATA", "test2");
       hd.startElement("", "", "MyTag", atts);
String curTitle = "Something inside a tag";
          hd.characters(curTitle.toCharArray(), 0, curTitle.length());
    hd.endElement("", "", "MyTag");
      hd.endDocument();
You are responsible for proper nesting. SAX takes care of encoding.

"The player used to create the project could not be found"

After installing Adobe Premiere Pro CC 2014, I have had issues with Encore, which worked fine before. This is the message I get when starting Encore:
"The player used to create the project could not be found, Adobe defaulting to Adobe player".
Once I attempt to open a saved project, the message is "Adobe Encore could not find any capable video play modules. Please update your video display drive and start again". I can't create a new project because the program crashes in the attempt.
I have uninstalled and reinstalled Encore. All drivers are up to date. I am running the program as an administrator.
Sony Vaio E Series
Windows 8
Any ideas what to do?

Hi Ann,
Thanks for responding - your answer improved things quite a bit - I installed the latest AMD driver, which seemed to help quite a bit - it added some functionality to Encore. I'm still getting an error message, but the program appears to be functioning in spite of it.
Thanks again

How do you create a stand alone application using DAQmx when your application SCXI hardware isn't on the computer I am using to create the application?

How do you create a stand alone application using DAQmx when your application SCXI hardware isn't on the computer I am using to create the application? The DAQmx assitant won't allow me to create a task with hardware that isn't in my system.

You will need to have at least the DAQ device in your computer to add the chassis. When you add the chassis, don't auto detect the modules. You will have to add the terminal blocks and tell MAX which SCXI module will be connected to the DAQ device. Just make sure you don't test the chassis, when its not there.
I hope this helps.
