Writing an XML file from JSP

Hi
for some this question will seem to be a stupid, but i am really confused how can i write an XML file from with in JSP code. should i have to use same FileOutPutStream.
Actually i am trying to make reports using Jasper api. It demands for an XML file which will then b converted into PDF file. Can any one help me in it.

Jasper converts a JSP into a servlet - and cannot be used to generate PDFs.
Assuming this is for a web application I would
1. Generate the XML
2. Generate the PDF from the XML
3. Send the PDF to the client from a servlet (i.e. forget the JSP).
Step 2 is actually quite complicated - you could do this manually with the IText API (http://www.lowagie.com/iText/) or use an XSL approach with Apache FOP (http://xmlgraphics.apache.org/fop/)

Read xml file from jsp/servlet

Hi all,
I am a new comer to jsp and really appreciate if someone can help me on this:
I will like to use a xml file to control access to my web app instead of using a database. Let say user.xml that will contains user name and password. Questions:
1. where should I put this file? Under WEB-INF?
2. In my jsp or servlet, how do i read the xml file, i mean how to i refer to the file (depend on question 1 as where the file should be placed)?
Thank you very much.
Sim

Hi jlsim,
you can place the xml file where you want, but remember that placing it under /WEB-INF is the most security way.
I had a similar problem and I placed the xml file under /WEB-INF directory.
To refer to it I did something like this:
String realPath=getServletContext().getRealPath("WEB-INF/xml/workspaces.xml");//obtain the real path
File f=new File(realPath);//obtain an instance of your file usable
//to create an InputStream

Writing XML file from a jsp page

how can i write a xml file from my jsp and store the values and after sometime, for example when the user clicks on the submit button, i check the values from xml file and compare those values from the data base.
it means both writing and reading xml file from a jsp page...
urgent help needed......thanks

You need some API like XSL or JDOM to read data from/to XML file
you can get a best tutorial from
http://www.javaworld.com/javaworld/jw-05-2000/jw-0518-jdom.html
and

after reading both articals you will be able to do both the tasks

Read XML file from different server on JSP

Dear All,
I am a newbie to JSP with XML, now i want to read the "test.xml" from JSP.
I read successfully this "test.xml" file from my system and I got output, but I need to read the xml file from
different server like "http://www.domain.com/test.xml". I couldn't read such a type of file from different server.
Is it possible to read a xml file from different server?
If anybody have idea please let me know.
Thanks in Advance,

You might try:
Document doc = docBuilder.parse ("http://www.domain.com/test.xml");Alternatively use the java.net package to obtain an Input Stream to the xml document
InputStream in = methodThatYouWriteYourselfCalledgetInputStreamForURI("http://www.domain.com/test.xml");
Document doc = docBuilder.parse (in);cheers,

Create XML file from table data

Dear All,
with dataservice 4.0, I want to create an XML file from a table data.
Table have a single column but more record, for example:
0001000488;100;EUR;
0001000489;200;EUR;
0001000450;300;EUR;
My desired XML output:
<Data>
0001000488;100;GBP;
0001000489;200;EUR;
0001000450;300;EUR;
</Data>
I try with a sample query but the sistem write only the last record in XML file:
<Data>
0001000450;300;EUR;
</Data>
Can everyone help me?
Thank in advance.
Simone

Hello
That is a very simple (also odd) XML document structure, and as such doesn't require use of the XML target. It can be easily acheived by writing a normal file with a header and footer, which is acheived using a row_generation and a query to generate the hard coded open and close tags.

Generate multiple XML files from one Invoices file in AR Selected Invoices

I have converted our Oracle EBS 11i Selected Invoice RAXINV.rdf to XML and created a template for XML Bursting. I'm bursting fine at the:
/ZRAXINV/LIST_G_ORDER_BY/G_ORDER_BY/LIST_G_CF_NO/G_CF_NO. My question is since I'm writing out my pdf output invoices to the filesystem on Sharepoint; I also need to archive the XML part of each invoice broken down by the same group as .//LIST_G_CF_NO/G_CF_NO. When I convert the rdf to XML it produces one XML file from which I created the templates.
My requirement is to archive both the individual invoices from the templates and the corresponding XML pieces on Sharepoint so that we will be able to search and link the xml to the pdf written out to the filesystem on Sharepoint.
Any idea how should go about this requirement will be much appreciated.
Thanks,
Leo

So how does it take this file
file>
<statement>
<name>John Dow </name>
<address>123 Main</address>
<phone>972-213-3434</phone>
</statement>
<statement>
<name>Jane Dow </name>
<address>345 Main</address>
<phone>972-213-3534</phone>
</statement>
<statement>
<name>Marry Dow </name>
<address>678 Main</address>
<phone>972-213-3435</phone>
</statement>
</file>
and create these three different one?
1.)
<statement>
<name>John Dow </name>
<address>123 Main</address>
<phone>972-213-3434</phone>
</statement>
2.)
<statement>
<name>Jane Dow </name>
<address>345 Main</address>
<phone>972-213-3534</phone>
</statement>
3.)
<statement>
<name>Marry Dow </name>
<address>678 Main</address>
<phone>972-213-3435</phone>
</statement>
Is it not going to just grab each element after the file tag? I'm just confused about that.

Best Practices:: How to generate XML file from a ResultSet

Hi all,
Could someone please suggest the best practices of how to generate an XML file from a resultset? I am developing a web application in Java with Oracle database and one of my tasks is to generate an XML file when the user, for example, click a "download as XML" button on the JSP. The application is basically like an Order with line items. I am using Struts and my first thought has been to have an action class which will extend struts's DownloadAction and through StAX's Iterator API to create an XML file. I intend to have a POJO which will have properties of all columns of my order and line items tables so that for each order I get all line items and:
1. Write order details then
2. Through an iterator write line items of that order to an XML file.
I will greatly appreciate for comments or suggestions on the best way to do this through any pointers on the Web.
alex

Use a OracleWebRowSet in which an XML representation of the result set may be obtained.

How I can create a XML file from java Aplication

How I can create a XML file from java Aplication
whith have a the following structure
<users>
<user>
<login>anyName</login>
<password>xxxx</password>
</user>
</users>
the password label must be encripted
accept any suggestion

Let us assume you have all the data from the jsp form in an java bean object..
Now you want a xml file. This can be acheived in 2 ways
1. Write it into a file using java.io classes. Say you have a class with name
write("<name>"+obj.getName+</name>);
bingo you have a flat file with the xml
2. Use data binding to do the trick
will recommend JiBx and Castor for the 2nd option

Generate an XML file from a DOM tree

Hi,
I'm trying to generate an XML file from a DOM tree that I obtained from another XML file with the Xerces library. I used the following operation :
public static void writeXmlFile(Document doc, String filename) {
try {
Source source = new DOMSource(doc);
File file = new File(filename);
Result result = new StreamResult(file);
Transformer xformer = TransformerFactory.newInstance().newTransformer();
xformer.transform(source, result);
} catch (TransformerConfigurationException e) {
System.err.println(e);
System.exit(1);
} catch (TransformerException e) {
System.err.println(e);
System.exit(1);
But I have this Windows/Linux problem. When I execute this on Windows, everything is correct. But if I try on Linux (every distribution does the same thing), I obtain an XML file where everything is written on just ONE LINE : there is neither identation nor carriage return at the end of a line ... And that is pretty annoying 'cause I need to SEE what I generate ...
Thanks for your answer,
Blueberryfin.

Actually I would think that no indents and no new-lines would be more correct, but maybe it's an option for parsers to do it either way if you don't specify it. If you want to specify it, look at this post from last month:
http://forum.java.sun.com/thread.jsp?forum=34&thread=383400

Error parsing XML file from a HttpServletRequest using JAXP

Hi,
I am trying to generate an XML file from an HttpServletRequest. I am actually using file uploading method in JSP to send the XML file. I think the parser isnt able to correctly identify the XML file from the message body and hence it is giving some strange error messages. Has anyone of u managed to solve this problem ?
Code snippet:
//now build an XML document from the requested input stream
InputStream in = myRequest.getInputStream();
try {
myDocRequest = myParser.parse(in);
} catch (Throwable t) {
throw new Exception("Could not build document",t);

Actually if i just print out the message, it gives something like this:
-----------------------------7d63dc71b06b2
Content-Disposition: form-data; name="W"; filename="C:\work_projects\Capas.xml"
Content-Type: text/xml
<?xml version="1.0" encoding="UTF-8"?>
<GetCapabilities version="1.0.0" service="wcs">
<section>/WCS_Capabilities/Capability</section>
</GetCapabilities>
-----------------------------7d63dc71b06b2--
Cheers.

The ServletInput stream contains this:
-----------------------------7d63dc71b06b2
Content-Disposition: form-data; name="W"; filename="C:\work_projects\Capas.xml"
Content-Type: text/xml
<?xml version="1.0" encoding="UTF-8"?>
i.e., its the HTTP File Upload MIME stuff, followed by the XML. You need to wrap around the input stream something that can decode the HTTP MIME stuff and let you get at the XML itself, i.e., something like: com.orielly.servlet.multipart.MultipartParser (Apache has a similar 'file upload servlet).

Sending xml file from client to servlet

Hi,
I am writing the server component of an applcation, such that it will receive xml files from the clients(standalone application similar to javaSwing stuff but it's coded in C#), and the servlet will have to extract the data from the xml file and update the mySql database. it will also fulfill the client's request for xmlFiles (and extract data from DB, format to xml file and send back to client)
I'm new to implementing the servlet receiving files from clients so would need some help.
I've got 3 questions to ask:
1) How does the servlet receive/returns the xml file from the client as a series of httpPost request/response. Do i send a File or the file's contents as a String to/from the client?
2) Is it also a must to use socket for the file transfers? I have read in other posts about sockets as well as HttpURLConnection but i don't quite understand.
3) When I send a file back to the client(client is standalone application written in C# whereas server is coded in java), what do i specify for the HttpResponse.setContentType() in my servlet? (i'm returning the xml file to client)
Would really appreciate for any help rendered. If you have any useful links, would appreciate them too. Thanks a lot.
Karen

I've got 3 questions to ask:
1) How does the servlet receive/returns the xml file
from the client as a series of httpPost
request/response. Do i send a File or the file's
contents as a String to/from the client?The server will listen on some port for requests. The client has to open a socket to this server to send the file as string to the server.
see http://java.sun.com/docs/books/tutorial/networking/index.html
>
2) Is it also a must to use socket for the file
transfers? I have read in other posts about sockets as
well as HttpURLConnection but i don't quite
understand.You use HttpURLConnection to make a request using the http protocol, instead of opening a socket and then writing the html headers yourself.
3) When I send a file back to the client(client is
standalone application written in C# whereas server is
coded in java), what do i specify for the
HttpResponse.setContentType() in my servlet? (i'm
returning the xml file to client)Its up to your receiving program how to interpret this though, so you probably dont need this.

How to retrieve xml file from BLOB and display on browser with css/xslt

Hi All,
I am new to xml. I am storing my xml file into BLOB in database. Now in my jsp page I want to retrieve this xml file from BLOB and display in HTML/CSS/XSLT form...
Pl. guide me.. any docs..?? Logic...??
Thanks in Advance.
Sandeep Oza

Hello Sandeep!
I'm not familiar with jsp but logic should be as follows:
-in jsp page instantiate XML parser
-load specified BLOB into parser
Now you may traverse the XML tree or you might load XSL file and use transform method to transform XML according to XSL file.
I have an example where I'm selecting XML straight from relational database and then transform it using XSL into appropriate HTML output, but it's written in PSP.
You can try http://www.w3schools.com/default.asp for basics on XML, CSS, XSL. It's easy to follow with good examples.

Access XML files from HTTP

Hi,
I need access XML file from HTTP. Server need parameters in the URL to generate XML files. For example, http://fileserver/xmlfile?orderid=123&custid=321.
I created a XML Data Server in ODI 11g. The JDBC Url should be jdbc:snps:xml?f=<filename>&s=<schema>&d=<DTD>.
However, it reports error when replaced the <filename> with "http://fileserver/xmlfile?orderid=123&custid=321".
I found it's caused by ampersand of the HTTP Url. I guess ODI treat custid=321 as JDBC parameter rather than HTTP parameter.
How to fill the JDBC Url in this situation?
Thanks,

i solved my problem by using the Socket object and controlling my file access by writing requests to the outputstream
