Hi Rob,

thanks for the reply, by authsope you meant, get the "realm" String using the authScope class ? I did saw that earlier but was not able to get more info about that ? can you please elaborate ?

thanks !

Ok, I was able to add authentication and encoding to the code, as of now the code looks something like this.
import org.apache.commons.codec.binary.Base64; import org.apache.commons.httpclient.HttpClient; import org.apache.commons.httpclient.HttpStatus; import org.apache.commons.httpclient.UsernamePasswordCredentials; import org.apache.commons.httpclient.methods.PostMethod; import java.io.BufferedReader; import java.io.ByteArrayOutputStream; import java.io.InputStreamReader; public class NCS2 { public static void main(String args[]) { String username = "abc"; String password = "xyz"; HttpClient httpclient = new HttpClient(); BufferedReader bufferedreader = null; PostMethod postmethod = new PostMethod("https://www.testabc.com/api/searches.xml"); postmethod.addParameter("_def_id","8"); postmethod.addParameter("dobday", "6"); postmethod.addParameter("dobmonth","6"); postmethod.addParameter("dobyear", "1960"); postmethod.addParameter("firstname", "Test"); postmethod.addParameter("lastname", "Test"); String username_encoded = new String(Base64.encodeBase64(username.getBytes())); System.out.println("username_encoded ="+username_encoded); String password_encoded = new String(Base64.encodeBase64(password.getBytes())); System.out.println("password_encoded ="+password_encoded); httpclient.getState().setAuthenticationPreemptive(true); UsernamePasswordCredentials credentials = new UsernamePasswordCredentials(); credentials.setPassword(username_encoded); credentials.setUserName(password_encoded); //httpclient.getState().setCredentials("", credentials); httpclient.getState().setCredentials("FORM","http://www.testabc.com/api/searches.xml",credentials); // I am not sure which one to use here.. try{ int rCode = httpclient.executeMethod(postmethod); System.out.println("rCode is" +rCode); if(rCode == HttpStatus.SC_NOT_IMPLEMENTED) { System.err.println("The Post postmethod is not implemented by this URI"); postmethod.getResponseBodyAsString(); } else if(rCode == HttpStatus.SC_NOT_ACCEPTABLE) { System.out.println(postmethod.getResponseBodyAsString()); } else { bufferedreader = new BufferedReader(new InputStreamReader(postmethod.getResponseBodyAsStream())); String readLine; while(((readLine = bufferedreader.readLine()) != null)) { System.out.println("return value " +readLine); } } } catch (Exception e) { System.err.println(e); } finally { postmethod.releaseConnection(); if(bufferedreader != null) try { bufferedreader.close(); } catch (Exception fe) { fe.printStackTrace(); } } } }


Using this I get the return value for rCode as "406". Why am I receiving a response which is "Not Acceptable" Anything which would help me debug better and fix this.

Hi,

Looking at all the cases/possibilities, i have opted to do this using httpclient or urlconnection class. I have not written the complete code but have just manage to write which would get us started atleast..

If I had used curl - I would have to write the following.

curl -u username:password -d "param1=aaa& param2=bbb" -k http://www.testme.com/api/searches.xml

this would have returned me an output in XML

with httpclient i think this could be done with something like this...
import org.apache.commons.httpclient.HttpClient; import org.apache.commons.httpclient.HttpStatus; import org.apache.commons.httpclient.methods.PostMethod; import java.io.BufferedReader; import java.io.InputStreamReader; public class HttpClientExampleTest { public static void main(String args[]) { HttpClient httpclient = new HttpClient(); BufferedReader bufferedreader = null; PostMethod postmethod = new PostMethod("https://www.testme.com/api/searches.xml"); postmethod.addParameter("param1","aaa"); postmethod.addParameter("params2", "bbb"); try{ int rCode = httpclient.executeMethod(postmethod); if(rCode == HttpStatus.SC_NOT_IMPLEMENTED) { System.err.println("The Post postmethod is not implemented by this URI"); postmethod.getResponseBodyAsString(); } else { bufferedreader = new BufferedReader(new InputStreamReader(postmethod.getResponseBodyAsStream())); String readLine; while(((readLine = bufferedreader.readLine()) != null)) { System.err.println(readLine); } } } catch (Exception e) { System.err.println(e); } finally { postmethod.releaseConnection(); if(bufferedreader != null) try { bufferedreader.close(); } catch (Exception fe) { fe.printStackTrace(); } } } }

With this, I have only taken care of the parameters, how to I pass the username and password with this ? any help ?
Also by default, with CURL the username and password is encoded with base64 internally, that would mean now I have to take care of 2 things

1. Encode the Username and password with base64 format
2. Accommodate the username and password in httpclient call.

thanks but how about doing it with curl ?

I asked the same question to my boss and the answer was yes. Just for curiosity what other ways are you referring to ,I know httpConnection class can be used.

Hi,

I am not sure if this is the correct place to post this, please feel free if the moderators can find a better place for this post. I have a general question regarding using curl (http://curl.haxx.se/) with Java. I have a web-application running in tomcat, based on certain actions in my web-applications I need to write a java code which would trigger curl. Curl would then query a third-party application and return an XML/JSON.

this has to be read by me and return appropriate response to the user.

Can this be done ? I see that curl has a binary distribution for Linux, once I download it (http://curl.haxx.se/download.html) how do I call this from my java web-app.

thanks !

Hi all,

I would like my java program to scan a document, is there a free api which I could make use of to scan a document ?

yes, I am trying to map the pojos to the database entities, like ORM, do we have any app that does that .?

HI all,

i have an xsd schema, I was able to create pojos from the given xsd schema, since the xsd was quite big, there are quite a few pojos involved, now my next step is to create a database to store these pojos. I would like to know is there a way by which tables in mysql could be created based on the pojos or xsd schema ?

If yes could you please let me know how ?

HI Eric,

well there is always a requirement, actually I am generating a pdf doc and I am displaying the pdf in the pop up (new window). the code below and the code which I have (same code basically) works only in Firefox and chrome but not in IE. In IE it still displays the location (address bar).

when you have a requirement, you need to fulfill it, its not worth asking for a workaround.. if the client is happy you are happy :P

anil

the solution given by Stan James was helpful however this works only in firefox, not in IE, in IE I still get the address bar on the top

any hints how do we do it in IE.

got the answer, actually in pdf ( ) - is one field while the remaining number is the other field, thus there are 2 fields to complete one phone number - same goes with fax.

can anyone throw some light on it please, below is the code and the explanation.

<%@ page import="com.itextpdf.text.Document" %> <%@ page import="com.itextpdf.text.pdf.*" %> <%@ page import="java.io.*" %> <%@ page import="java.util.*" %> <html> <% HashMap data = new HashMap(); String readResponse = ""; String code = ""; String outurl = ""; String uemail[] = new String[1]; String recordID = (String)request.getParameter("recordID"); String useremail = (String)request.getParameter("useremail"); uemail[0] = useremail; Result result = getResult(recordID); int resultCode = result.getCode(); if(resultCode != 1) { } else { Parameters resultParameters = result.getParameters(); HashMap readMap = readResult(resultParameters); readMap = getFormData(readMap); ServletContext context = getServletContext(); String templatePath = context.getRealPath("/pdfdocs"); com.platform.c892085391.pdf.PdfUtils utils = new com.platform.c892085391.pdf.PdfUtils(); String fileName = utils.getFileName(); PdfReader reader = new PdfReader(templatePath + "/8655.pdf"); try { String outputfileName = templatePath + "/output/"+fileName+".pdf"; PdfStamper stamp = new PdfStamper(reader, new FileOutputStream(outputfileName)); AcroFields form = stamp.getAcroFields(); HashMap fields = new HashMap(); fields = form.getFields(); form.setField("f1_10(0)",(String)readMap.get("phone")); form.setField("f1_12(0)",(String)readMap.get("fax")); form.setField("f1_01(0)",(String)readMap.get("name")); stamp.setFormFlattening(true); stamp.close(); com.platform.c892085391.pdf.PDFSendeMail sendmail = new com.platform.c892085391.pdf.PDFSendeMail(); sendmail.processEmails(outputfileName,uemail); } catch(IOException e) { out.println("Error: " + e); } } %> <body> </body> </html>

In the try block, I am trying to set the values for the pdf form i.e
form.setField("f1_10(0)",(String)readMap.get("phone"));
, now say in the html I have a phone field which has a value (1234567890) in the pdf for the same phone field I will have ( ) 12345678 .

Can any one help me with this.

Hi all,

I am a newbie to using Itext API, so far it has been a nice experience, however I am currently being faced with a problem and would appreciate if anyone could help in to find the answers.

I am trying to write to an existing pdf (filling an existing pdf with data), the code works just fine, however I am unable to write to fields like "Phone" and "Fax" correctly. The fields like "phone" and "Fax" have something like this [( ) ] (exclude the [ ]) when i try to write into these fields the text which is displayed is something like this [( ) 2222232]. Can any one let me know how to fix this ?

Would appreciate your help.

Regards
