How to upload a XML file to Servlet

Hi,
I am new to Java, I have to upload an XML file to java/j2ee server. The web server running on the server is "Tomcat 4.1". My new requirement is I have to upload an "Input.XML" file, can you please tell me how to upload an XML file. If any samples appriciated very soon.
Thanks & Regards,

Hi!
On the client side, the client's browser must support form-based upload. Most modern browsers do, but there's no guarantee. For example,
<FORM ENCTYPE='multipart/form-data'
method='POST' action='/myservlet'>
<INPUT TYPE='file' NAME='mptest'>
<INPUT TYPE='submit' VALUE='upload'>
</FORM>
The input type "file" brings up a button for a file select box on the browser together with a text field that takes the file name once selected. The servlet can use the GET method parameters to decide what to do with the upload while the POST body of the request contains the file data to parse.
When the user clicks the "Upload" button, the client browser locates the local file and sends it using HTTP POST, encoded using the MIME-type multipart/form-data. When it reaches your servlet, your servlet must process the POST data in order to extract the encoded file. You can learn all about this format in RFC 1867.
Unfortunately, there is no method in the Servlet API to do this. Fortunately, there are a number of libraries available that do. Some of these assume that you will be writing the file to disk; others return the data as an InputStream.
You can see more things about Servlet on this website [http://pedrofao.blogspot.com|http://pedrofao.blogspot.com].

How to upload an XML file into another system

Hi friends,
I have a requirement where I need to upload an XML file into one system
which has been downloaded using another system.
I have tried using the method ' cl_gui_frontend_services=>gui_upload'
to upload the file but it is going for dump.
I have used the method ' w_xml->import_from_file' also,
but it is also going for dump ,because both methods are using the same FM
' GUI_UPLOAD'.
Can any one suggest on this.

"Here is the Explaination for uploading the XML Format file to sap " through ABAP Program ....
1. Basically you simply have to convert the XML file into the proper IDoc format. There are many ways to achieve this. One solution would be to convert it externally to SAP, e.g. via VB Script or with an XSLT transformation. Or you use the built in SAP functions for importing an IDoc from an XML stream.
2. Uploading a file is either done via GUI_UPLOAD or via the usual way of reading a file from the application server (Open dataset. Read dataset) But what do you mean by "send to external system"? Do you want to convert an IDoc into XML? Then you simply define an XML port with WE21 to send the IDoc out.
Here is an example of code that loads an XML from file and posts it as an IDoc. Please keep in mind that the XML has to be in its canonical format as described in the interface repository: ifr.sap.com (choose the template of the desired IDoc from there as an example).
data: data_tab type table of char1024.

How to parse the xml file using servlet

My scenario is like this:
FILE-->XI-->J2EE Application
XI sends the xml file to j2ee application. My servlet receives the file in HTTPRequest string.
How to parse that file using servlets.I should get the xml file as it is and should be displayed in the browser.
Can anyone please help me with code, its urgent.
Please help me!

Download this java code
http://java.sun.com/webservices/jaxp/dist/1.1/docs/tutorial/sax/work/Echo02.java
in your servlet code you can write
public void doPost(req,resp){
DefaultHandler handler = new Echo02();
handler.parse(req.getInputStream());
Offcourse you will need to modify the code of Echo02 class a bit to suit your requirement which would finally retrun you a string and you can then write it using
respose.getWriter().write(responseString);

How to upload a XML File in database

i use Blob type to set domain the Xml file. But i don't know use what class to define it.i only know use OrdHttpUploadFile to define a image. What class do i use to define a Xml file.

during my tries to adapt this code to my needs, following error occured during compilation of the procedure:
PLS-00201: identifier 'IMAGES.MIME_TYPE' must be declared
here is my procedure:
CREATE OR REPLACE PROCEDURE load_file( file_name VARCHAR2 )
AS file_lob BFILE;
binary_lob BLOB;
mime_type images.mime_type%TYPE;
extension_pos NUMBER;
BEGIN
--Use the extension of the file name to determing the MIME-type
--The MIME-type for a .pdf file will be application/pdf
extension_pos := INSTR( file_name, '.' );
mime_type := 'application/' || SUBSTR( file_name,extension_pos + 1,LENGTH( file_name ) );
-- Insert a new row into the images table. Get the LOB locator
-- for the newly inserted row
-- we will be using that to insert
-- the content from the file.
INSERT INTO TESTBLOB( blobid, filename, mime_type, content )
VALUES( 1, file_name, mime_type, EMPTY_BLOB() )
RETURNING content INTO binary_lob;
-- Open up the file in the IMAGES directory named file_name,
-- load that file into the newly created LOB locator, and
-- close the file
file_lob := BFILENAME( 'TESTDIRECTORY', file_name );
dbms_lob.fileOpen ( file_lob, dbms_lob.file_readOnly );
dbms_lob.loadFromFile( binary_lob,file_lob,dbms_lob.getLength( file_lob ) );
dbms_lob.fileClose ( file_lob );
END;
how do I have to adjust the declaration of the mime_type variable respectively what does images.mime_type%TYPE mean?

How do I upload an XML file to salesforce using BULK API?

Hi There,
Please let me know how do we upload an XML file to salesforce using Bulk API?
Thanks,
ET

Hi,
I think that this is a more SalesForce.com question and think you will have more chance looking at SOAP API Developer's Guide for salesforce. Sending a SOAP request from the API Server is very straight forward and there are several tutorials and well documented about this.
Cheers,

Keeping contact with controlling applet while u/l XML file via servlet

Hello everybody,
if I am thinking too complicated, please send me other suggestions. Here's the situation:
I already have a working applet for a metadata application, that is sending the contents of the client's textfields to a remote database via servlet communication. Now I want to implement the following:
-The users have some attribute data in form of an XML file
-I want them to upload this file to the server (I already have that functionality using the fileUpload libraries of Apache Commons) by calling the servlet from a pop-up html page (is there any other possibility to do the communication, i.e. getting files from the file system?)
-the XML file should be parsed on the server and the content should be sent back to the calling applet for previewing reasons.
-when the user gives his/her O.K. the data should be transferred to the database.
Now there are some obstacles to overcome: When I upload the XML file to the server, I loose "contact" with the applet, i.e. the file is not connected with the applet code in any way. This is not a problem, when there is only one user at the time, but with many users loading up their data at the same time, things could get tricky.
What I thought was to copy the XML file to a temp directory with a unique name, the name of which would be transferred back to the applet by another servlet that is called when the (upload)pop-up window closes. The name of the temp directory could be the ID of the applet thread (is there such an ID, if yes, how can it be retrieved?)
Any suggestions (or just shaking heads concerning my complicated construction ;-) )
Cheers and many thanks in advance
Jan

You may be able to read a file from the file system with the applet, but it may require you to sign the applet. If you can, then use an HttpURLConnection to the servlet and send the file that way.
On the server side, you could create a session object (wether you actually need a session or not), and use the session's id as the key id for the directory name for the uploaded file. Session IDs are unique per client, and if the client handles cookies, then the same session will be used from one request to the next.
session = request.getSession();
String sessionID = session.getId();The response from the servlet would be a link to the server-side file. If you are using the Applet to send the request, you could get the response and automatically view the new file. Otherwise, you could send a page to the popup window saying: "Click This Link To See Your File" type of thing.

How to transfer an xml file to NW Portal Knowledge Management from XI?

Hi all,
Anybody knows how to transfer an xml file to NW Portal Knowledge Management from XI?
What kind of adapter type I have to choose? And which procedures I have to do in KM Portal? Create a folder, what kind of folder and permissions?
Suggestions and ideas are appreciated.
Thanks in advance,
Ricardo.

Hi
Can anyone tell me how XI sends messages to applications like J2EE. In REceiver comm channel, I think we specify about the target system like J2EE appl.
Aadapter Type: HTTP
               Receiver
Transport Protocol: HTTP1.0
Message Protocol:    XI payload in HTTP body
Adapter Engine:      Integration Server
Addressing Type:     URL address
Target host:         localhost
Service Number:      7001(Port number of Weblogic appl server--where my J2EE appl is deployed).
Path     : /Invoke/DisplayRes/
Authentication Type:Use Logon Data for SAP System
Content Type: text/xml
Username:   xiappluser
password:   xx
XML code:   UTF-8
I suppose XI sends msgs to http://localhost:7001/Invoke/DisplayRes/........
in this example if am correct?
Then I have given all tyhe necessary setting but my servlet is not able to display XML msg in browser?
This is my servlet code:
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
     PrintWriter out = response.getWriter();
     BufferedReader brin =new BufferedReader(new InputStreamReader(request.getInputStream()));
     String inputLine;
     StringBuffer sBuf = new StringBuffer();
        response.setContentType("text/xml");
     while ((inputLine = brin.readLine()) != null)
         sBuf.append(inputLine);
         out.println("hi");
            out.println(sBuf.toString());
         brin.close();
         out.flush();
What went wrong?
Help me, all helpful answers are highly rewarded.
Thanks

The Oracle documentation has a good overview of the options available

How to upload a text file from a shared folder and provide an o/p

how to upload a text file from a shared folder and provide an o/p containing the details in each order in the text file

Hi,
Use GUI_UPLOAD to upload a text file from a shared folder.
Use GUI_DOWNLOAD to download data in a file on the presentation server or use OPEN DATASET, TRANSFER and CLOSE DATASET statements to download data to the application server.
Now, I hope the code for data fetching, if required, is already present in the report.

How to Merge multiple XML files in one file ( Env: XML Publisher 5.6.2)

All,
I have recently started working on XML publisher and have developed 3 reports in last 2 days using XML Publisher and integrating them with Concurrent programs.
This is a great tool.
I have got another requirement, where i need to use xml file generated by multiple run of same report with various parameters and then merge all xml file to a single report. Developing the whole custom process will take very long time and sure will have bugs in it. Instead i was thinking to use xml file generated by Oracle report itself.
Report "US Gross to net summary" generates xml output in standard output directory and then show output in PDF file. I have 7 such file generated for each payroll. I want to merge output of xml into a single xml so that i can create single report having data from all 7 xml files showing me All payroll output in a single report.
Can someone please guide me , how can i read xml file data from the output directory of a seeded concurrent program and how to manipulate data in it.
Thanks
Ankur

Hi Tim,
Thanks for replying. I have looked for "PDFBookBinder class" in xml publisher user guide for ver 5.6.2. I didn't get any reference of this text. Can you please guide me to a tutorial/link where i can get more information about this class.
Also, i originally thought of similar to your second logic, as my design basis. Oracle process generates the xml file in output directory which i can get. What i didn't get is how do i "pick them up and merge" using publisher. Also, is there way to do this merging process using pl/sql ? Can you please give little more information on your second approach.
My original plan of action is that i will create a report set in which i will call oracle seeded report for all 7 payrolls in a sequential manner. Then using the child requests of the report set i will get to 7 xml files generated by seeded oracle process. Then the piece i am not sure of , i will use those 7 files to generate a single xml file having payroll name as tree top for each output. Once single xml is ready, i can easily design a template and register the process to generate output as Excel.This process will not require me to actually change any data or do any calculation. It will only reformatting the feilds we see and abiity to see all 7 payroll at one time rather then entering these numbers manually into an excel to do analysis.
Please provide your feedback, if you think above plan is not feasible or need corrections.
Best Regards,
Ankur

Uploading an XML file from SAP into third party URL

Hi,
I need to Upload an XML file from sap into Third party URL. Can any body tell me the possible ways in SAP to achieve this task. Also explain me the proceedure.
Thanks in advance.
-Namdev

Sorry. If they only said HTTP/HTTPS and didn't say explicitly web service, it means they don't want it.
One thing I'm not sure is, do you have an URL at the third-party system that you need to contact, or should you provide one at your SAP system that they will contact?
If it is the first one, to send an HTTP request to a given URL using ABAP, you'll find an example here: [SAP Library: Example Program: Executing an HTTP Request|http://help.sap.com/saphelp_nw70/helpdata/en/1f/93163f9959a808e10000000a114084/frameset.htm]
