Code to read URL

I have seen the following kind of code:-
req := utl_http.begin_request('http://10.22.11.45/HISGatewayV34/Hisgateway?user=kunal=pdg=fascel=Gujarat=RS='
||v_Mobileno||'=2007-01-01=2007-03-06');
utl_http.set_header(req, 'User-Agent', 'Mozilla/4.0');
resp := utl_http.get_response(req);
LOOP
utl_http.read_line(resp, v_ResponseTxt, TRUE);
to read a URL. I am not able to understand the use of statements like 'utl_http.begin_request', utl_http.set_header, utl_http.get_response & utl_http.read_line used above. Is there any place where i can get help on this or if a explanation can be given.
I hope, my question is clear. Please help in solving the doubt.
regards.

Access to UTL_HTTP is restricted - along with packages like UTL_TCP, UTL_MAIL, and a few others. The concern is security, so public access to these packages are not granted when the Oracle instance & database is created and installed.
As your DBA to grant your schema execute access on UTL_HTTP.

Finally I solved my problem(getting as many images as possible from a url infinitely) using the above code:
import java.net.*;
import java.io.*;
public class UserApplication {
    private static int n=0;
    String url;
public void UserApplication(){
    public static void main(String[] args) throws Exception {

        for(;;){
        app.urlStr();
    private void urlStr(){
        try{
            url= "http://mplamplampla/frame.php/";
            HttpURLConnection con=(HttpURLConnection) ((new URL(url).openConnection()));
            BufferedOutputStream out = new BufferedOutputStream( new FileOutputStream("C:\\Users\\mpla\\Desktop\\" + n + ".jpeg"));
            con.setDoInput(true);
            con.setDoOutput(false);
            con.setRequestMethod("GET");
            BufferedInputStream in = new BufferedInputStream(con.getInputStream());
            int bt = 0;
            byte[] buffer = new byte[4096];
            while ((bt = in.read(buffer, 0, 4096)) > -1) {
              out.write(buffer, 0, bt);
            in.close();

http response 505: http://libraries.ucsd.edu/about/tools/http-response-codes.html
This would indicate nothing is wrong with your applet but with your http server (not supporting http 1.1??)
A full trace might help:
To turn the full trace on (windows) you can start the java console, to be found here:
C:\Program Files\Java\j2re1.4...\bin\jpicpl32.exe
In the advanced tab you can fill in something for runtime parameters fill in this:
-Djavaplugin.trace=true -Djavaplugin.trace.option=basic|net|security|ext|liveconnect
if you cannot start the java console check here:
C:\Documents and Settings\userName\Application Data\Sun\Java\Deployment\deployment.properties
add or change the following line:
javaplugin.jre.params=-Djavaplugin.trace\=true -Djavaplugin.trace.option\=basic|net|security|ext|liveconnect
The trace is here:
C:\Documents and Settings\your user\Application Data\Sun\Java\Deployment\log\plugin...log
When you catch the exception you should print the stacktrace: (e.printStackTrace()).

Hi Santosh,
You can read parameters send from one WebDynpro Component to another component by adding code in "HANDLEDEFAULT" Event Handler method ( Window )of your target Web Dynpro Component.
data: lt_parameter             type tihttpnvp,
         ls_parameter             type ihttpnvp.
lo_api_controller ?= wd_this->wd_get_api( ).
   call method lo_api_controller->get_message_manager
     receiving
       message_manager = lo_message_manager.
   clear : ls_parameter.
   refresh : lt_parameter[].
* Read all URL parameters
   wdevent->get_data( exporting name = if_wd_application=>all_url_parameters importing value = lt_parameter ).
if not lt_parameter[] is initial.
     clear : ls_parameter.
     read table lt_parameter into ls_parameter index 1.
     if ls_parameter-name = 'ACTION' and
        ls_parameter-value is initial.
       lv_flag = 'X'.
       clear : lo_msg.
       lo_msg = 'Action Parameter Missing in URL Link !'.
*         report message
       call method lo_message_manager->report_error_message
         exporting
           message_text = lo_msg.
     else.
     endif.

Read URL parameters

Hi guys!
Is posible read url parameters from a WD for Java?
e.g.: http://server/webdynpro/dispatcher/local/TestApp/TestApp?SAPtestId=1&myVariable=123
Then read value 123 from some code inside WD (controller, view, whatever).
Thanks!

Hi,
You can do it, see this reference: Pass URL parameters to SAP Portal from an external application

BufferedImage 'null' with ImageIO.read(url)

Hi,
I am trying to display a JSP as an image which can be used in another JSP's img tags.
Here is how I coded image.jsp.
I observed that for 'bmp' image type, image object is 'null'. When I directly open 'bmp' image url in browser, it opens correctly.
<%@ page import = "java.io.*" %>
<%@ page import = "java.awt.image.BufferedImage"%>
<%@ page import = "javax.imageio.ImageIO"%>
<%@ page import = "javax.imageio.spi.IIORegistry"%>
<%@ page import = "java.net.URL"%>
<%@ page import = "java.net.URLEncoder"%>
<%
     try{
          String imgUrl = URLEncoder.encode(request.getParameter("imgUrl"));
          imgUrl = imgUrl.replaceAll("%3A",":");
          imgUrl = imgUrl.replaceAll("%2F","/");
          imgUrl = imgUrl.replaceAll("\\+","%20");
          String[] urlSplit = imgUrl.split("\\.");
          String imgTyp = urlSplit[urlSplit.length-1];
          URL url = new URL(imgUrl);

Hi EJP,
Thanks for reply.
I now changed my code to this: -
<%@ page import = "java.io.*" %>
<%@ page import = "java.awt.image.BufferedImage"%>
<%@ page import = "javax.imageio.ImageIO"%>
<%@ page import = "javax.imageio.spi.IIORegistry"%>
<%@ page import = "java.net.URL"%>
<%@ page import = "java.net.URLEncoder"%>
<%@ page import = "com.sap.tc.logging.Location"%>
<%
     Location location = Location.getLocation("AmeyTestPar.imageJSP");
     try{
          String imgUrl = request.getParameter("imgUrl");
          location.fatalT("imgUrl = " + imgUrl);
          String[] urlSplit = imgUrl.split("\\.");
          String imgTyp = urlSplit[urlSplit.length-1];
          URL url = new URL(imgUrl);
          BufferedImage bufferedImage = ImageIO.read(url);
          OutputStream outputStream = response.getOutputStream();
          response.setContentType("image/"+imgTyp);
          ImageIO.write(bufferedImage,imgTyp, outputStream);
          outputStream.flush();
          outputStream.close();
   }catch (Exception e){
          location.fatalT("Exception in image.jsp : " + e.getMessage());
         e.printStackTrace();
%>But this is running into 'java.lang.IllegalArgumentException: im == null!" at
jvax.imageio.ImageIO.write(ImageIO.java:1413)
and
jvax.imageio.ImageIO.write(ImageIO.java:1508)
Also, I heard about use of image type plugins in package 'javax.imageio.plugins'.
I added 'jai_imageio-1.1.jar' in build path and inserted 'ImageIO.scanForPlugins()' line in code.
But this didn't help either.
With regards,
Amey

Read URL using URLReader

I am trying to read a specific URL using URLReader, as described in
http://java.sun.com/docs/books/tutorial/networking/urls/readingURL.html
The code is the following:
import java.net.*;
import java.io.*;
public class URLReader {
public static void main(String[] args) throws Exception {
     URL yahoo = new URL("http://www.yahoo.com/");
     BufferedReader in = new BufferedReader(
                    new InputStreamReader(
                    yahoo.openStream()));
     String inputLine;
     while ((inputLine = in.readLine()) != null)
     System.out.println(inputLine);
     in.close();
The code is working fine with 90% of the URL's I am using.
Still it doesn't work for the URL I need it for.
Specifically, I need to open URLs from www.imdb.com like the following:
http://us.imdb.com/M/title-exact?Kika%20(1993)
which means that I should replace the corresponding line from the code above with:
URL yahoo = new URL("http://us.imdb.com/M/title-exact?Kika%20(1993)")
When I run the program though, after I make that change, it just hangs without doing anything.
Some people in the past, advised me to set the proxy correctly.
prop.put("http.proxyHost","myproxy.someplace.com");
prop.put("http.proxyPort","80");
Nevertheless, the system administrator here assured me that we are not using a proxy.
So, is there another way to read the specific URL I need to, using the URLReader code?
If so, how can it be done?
Again, the URL I am trying to handle is:
http://us.imdb.com/M/title-exact?Kika%20(1993)
Thanks,
manolis

Still, I am pretty sure that the problem is not with the way I am writting the URL itself
I even tried hardcoding the URL as suggested, and as it could have been encoded by using URLEncode, ie
http://us.imdb.com/M/title-exact?Kika%20%281993%29
and still it didnt work. The program would just hang there and not do anything.
It wont even read a much simple, but similar URL, like
http://www.imdb.com/
So, any more suggestions would be more than welcome.
Thanks,
Manolis

Has anybody written a Java program to get Source code from a URL ?

Hi,
I have a program written in another language (Not Java) to basically
pull in the source HTM or HTML code, given a URL.
ex. getsource www.any.com output
So, ==> output will contain the source HTM or HTML code of
www.any.com.
Is there a Java program that do the same ? Like to see it.
Please append here, or provide pointer to get it.
Thanks,.... -- gte99te

Here's a quick program that does just that.
I'd suggest taking a look at the Java Tutorial, at it's section on using URLs descibes how to do this, and it shouldn't tank more than 45 minutes to get through.
import java.io.*;
import java.net.*;
public class SavePage{
    public static void main(String[] args) throws Exception
     // make sure we've been given a URL
     if (args.length != 2)
         System.err.println("Usage: java SavePic <URL> <filename>");
         System.exit(1);
     // convert the string argument to a URL
     URL url = new URL(args[0]);
     // open a connection to the resource with the given URL
     URLConnection connection = url.openConnection();
     // get an input stream from the connection, and wrap it in a buffer
     BufferedInputStream bis = new BufferedInputStream(connection.getInputStream());
     // open an output file and get an output stream to it
     FileOutputStream file = new FileOutputStream(new File(args[1]));
     // wrap[ the file's output stream in a buffer
     BufferedOutputStream bos = new BufferedOutputStream(file);
     // read each byte from tne connection, and write it to the file     int b;
     while( (b = bis.read()) != -1 )
         bos.write(b);
     // clean up
     bis.close();
     bos.close();
}

AutoVue applet return HTTP response code: 403 for URL with chinese characte

Dear All,
When i integrate with AutoVue Server 19.3 Using AutoVue applet into my web application it returns the following exception
java.io.IOException: Server returned HTTP response code: 403 for URL: http://.....
when the file name have chinese characte,but when the file name have no chinese characte and all the normal
Anyone can help?
Best Regards

There are many possible causes of a 403 error. Is this error happening when launching the applet, or does the applet launch properly and the error comes up when loading the file? How do you have AutoVue integrated to your web application? Is it integrated using the AutoVue ISDK? Or are you passing filenames into the applet in a different way? Can you clarify again, does the error only occur when the user tries to open a Chinese filename?
Also, please note that AutoVue version 19.3 is no longer under Oracle Premier Support. If possible you should upgrade to the latest version of AutoVue, especially if you end up needing to log a Service Request to Oracle.

How to code in the URL to have a default show up in the search section.

Hi All,
I have a query in CRM-PCUI. Do anyone know how to code in the URL to have a default show up in the search section. I do not want to set it in the settings since it needs to be changed for each search criteria each time. Or if this can be defaulted using a view how would that be done?
Thanking you in advance.
Thanks and Regards,
Chirag Mehta.

Hi Karthik,
Thanks for Replying.
No that is unfortunately not what i want but to pass with the URL any parameter so that i can get the Show drop down to have a default show up in the search section.
Thanks and Regards,
Chirag Mehta.

Help!!! T61 Blue Screen--unmountable boot volume-- error code 0000: Read verification failed

My computer is T61 (8891CT), but Blue Screen came out and reported--unmountable boot volume. I ran the diagnostic program and got the error code 0000: Read verification failed. I can’t run anything now including the restore and rescue. Has the hard drive died?
If the hard drive has died, I have to change the hard drive, but how to transfer the system (I don’t have any CD) and think vantage software? Thank you very much for you help.

Hi equalefk,
Yes, definitely sounds like it's time to replace the HDD.
Hope it helps.
