I have an ASP application that uploads a PDF file through Request.BinaryRead(Request.TotalBytes). The requests that I make, are made through a java application. The problem is that I have method in Java that iterates through the Header Field Keys of the object HttpURLConnection. When the iteration is made I get in my ASP code an error "cannot call binaryread after using request.form".
Here is my java code:
public String getCookieValue(HttpURLConnection con, String cookieKey) {
String cookieValue = null;
String headerName = null;
for (int i = 1; (headerName = con.getHeaderFieldKey(i)) != null; i++) {
if (headerName.equals("Set-Cookie")) {
String cookie = con.getHeaderField(i);
cookie = cookie.substring(0, cookie.indexOf(";"));
String cookieName = cookie.substring(0, cookie.indexOf("="));
if (cookieName.equals(cookieKey)) {
cookieValue = cookie.substring(cookie.indexOf("=") + 1, cookie.length());
}
}
}
return cookieValue;
}
The exact line of java code that breaks my ASP application is con.getHeaderFieldKey(i). When I upload the file without this Java application, the file is uploaded properly.
What can I do to bypass this issue ?
Thank you
Actually the problem here was that we are using a wrapper for the Session object. When we are trying to retrieve the information regarding the session Id we are using the Request.From method, and this intervenes with the Request.BinaryRead method which generates an error.

I am trying google drive api to search parents of a folder. In search query i have to pass file id dynamically instead of hard coding. I tried below code. but I am getting file not found json response.
here its not taking fileId as value i think its consider as String
if I hardcode the value it is working.
FileList result = service.files().list().setQ("name='testfile' ").execute();
for (com.google.api.services.drive.model.File file : result.getFiles()) {
System.out.printf("Found file: %s (%s)\n",
file.getName(), file.getId());
String fileId =file.getId();
FileList childern = service.files().list().setQ(" + \"file.getId()\" in parents").setFields("files(id, name, modifiedTime, mimeType)").execute();
This should help.
String fileid=file.getId()
service.files().list().setQ("'" + fileId + "'" + " in parents").setFields("files(id, name, modifiedTime, mimeType)").execute();
Make sure you have valid file.getId()
I know your question states java but the only sample of this working is in C#. Another issue is as far as i know PageStreamer.cs does not have an equivalent in the java client library.
I am hoping that C# and java are close enough that this might give you some ideas of how to get it working in Java. My java knowledge is quote basic but i may be able to help you debug it if you want to try to convert this.
try
{
// Initial validation.
if (service == null)
throw new ArgumentNullException("service");
// Building the initial request.
var request = service.Files.List();
// Applying optional parameters to the request.
request = (FilesResource.ListRequest)SampleHelpers.ApplyOptionalParms(request, optional);
var pageStreamer = new Google.Apis.Requests.PageStreamer<Google.Apis.Drive.v3.Data.File, FilesResource.ListRequest, Google.Apis.Drive.v3.Data.FileList, string>(
(req, token) => request.PageToken = token,
response => response.NextPageToken,
response => response.Files);
var allFiles = new Google.Apis.Drive.v3.Data.FileList();
allFiles.Files = new List<Google.Apis.Drive.v3.Data.File>();
foreach (var result in pageStreamer.Fetch(request))
{
allFiles.Files.Add(result);
}
return allFiles;
}
catch (Exception Ex)
{
throw new Exception("Request Files.List failed.", Ex);

I need to implement email confirmation in my java web application. I am stuck with the email I have to send to the user.
I need to combine a template (of an confirmation email) with the User object and this will be the html content of the confirmation email.
I thought about using xslt as the template engine but I don't have xml form of the User object and don't really know how to create a xml from User instance.
I thought about jsp, but how do I render jsp page with an object and get the html as a result?
Any idea what packages I can use in order to create templae and combine it with an object?
I have used the following before. I seem to recall it wasn't complicated
http://velocity.apache.org/
How complex is the user object? If it's just five string-valued fields (say) you could simply supply these as string parameters to the transformation, avoiding the need to build XML from your Java data.
Alternatively, Java XSLT processors typically provide some way to invoke methods on Java objects from within the XSLT code. So you could supply the Java object as a parameter to the stylesheet and invoke its methods using extension functions. The details are processor-specific.
Instead of learning a new code, debug other's complicate code I decided to write my own small and suitable util:
public class StringTemplate {
private String filePath;
private String charsetName;
private Collection<AbstractMap.SimpleEntry<String, String>> args;
public StringTemplate(String filePath, String charsetName,
Collection<AbstractMap.SimpleEntry<String, String>> args) {
this.filePath = filePath;
this.charsetName=charsetName;
this.args = args;
}
public String generate() throws FileNotFoundException, IOException {
StringBuilder builder = new StringBuilder();
BufferedReader reader = new BufferedReader(new InputStreamReader(
getClass().getResourceAsStream(filePath),charsetName));
try {
String line = null;
while ((line = reader.readLine()) != null) {
builder.append(line);
builder.append(System.getProperty("line.separator"));
}
} finally {
reader.close();
}
for (AbstractMap.SimpleEntry<String, String> arg : this.args) {
int index = builder.indexOf(arg.getKey());
while (index != -1) {
builder.replace(index, index + arg.getKey().length(), arg.getValue());
index += arg.getValue().length();
index = builder.indexOf(arg.getKey(), index);
}
}
return builder.toString();
}
}
I want to import data from java web application to sugarCRM. I created client stub using AXIS and then I am trying to connect, it seems it is getting connected, since I can get server information. But after login, it gives me error while getting sessionID:
Error is: "faultString: org.w3c.dom.DOMException: WRONG_DOCUMENT_ERR: A node is used in a different document than the one that created it."
Here is my code:
private static final String ENDPOINT_URL = " http://localhost/sugarcrm/service/v3/soap.php";
java.net.URL url = null;
try {
url = new URL(ENDPOINT_URL);
} catch (MalformedURLException e1) {
System.out.println("URL endpoing creation failed. Message: "+e1.getMessage());
e1.printStackTrace();
}
> System.out.println("URL endpoint created successfully!");
Sugarsoap service = new SugarsoapLocator();
SugarsoapPortType port = service.getsugarsoapPort(url);
Get_server_info_result result = port.get_server_info();
System.out.println(result.getGmt_time());
System.out.println(result.getVersion());
//I am getting right answers
User_auth userAuth=new User_auth();
userAuth.setUser_name(USER_NAME);
MessageDigest md =MessageDigest.getInstance("MD5");
String password=convertToHex(md.digest(USER_PASSWORD.getBytes()));
userAuth.setPassword(password);
Name_value nameValueListLogin[] = null;
Entry_value loginResponse = null;
loginResponse=port.login (userAuth, "sugarcrm",nameValueListLogin);
String sessionID = loginResponse.getId(); // <--- Get error on this one
The nameValueListLogin could be be from a different document context (coming from a different source). See if this link helps.
You may need to get more debugging/logging information so we can see what nameValueListLogin consists of and where it is coming from.
My Java web application contains a startup servlet. Its init() method is invoked, when the web application server (Tomcat) is started. Within this method I need the URL of my web application. Since there is no HttpServletRequest, how to get this information?
You can't. Because there is no "URL of an Java web application" as seen "from within". A servlet is not tied to an URL, that is done from the outside. (Perhaps you have a Apache server that connects to a Tomcat - Tomcat can't know about it)
It makes sense to ask a HttpServletRequest for its url, because we are speaking of the information of a event (the URL that was actually used to generate this request), it does not make sense to ask for a configuration URL.
A workaround could be to perform the initialization lazy when the first request arrives. You can implement a filter that do that once, e.g. by storing a boolean flag in a static variable and synchronizing access to the flag correctly. But it implies a little overhead because each subsequent request will go through the filter which then bypass the initialization. It was just a thought.
There is nothing in the servlet API that provides this information, plus any given resource may be bound to multiple URL's.
What you CAN do, is to inspect the servlet context when you receive an actual request and see what URL was used.
Here is how it works for me and probably for most configurations:
public static String getWebappUrl(ServletConfig servletConfig, boolean ssl) {
String protocol = ssl ? "https" : "http";
String host = getHostName();
String context = servletConfig.getServletContext().getServletContextName();
return protocol + "://" + host + "/" + context;
}
public static String getHostName() {
String[] hostnames = getHostNames();
if (hostnames.length == 0) return "localhost";
if (hostnames.length == 1) return hostnames[0];
for (int i = 0; i < hostnames.length; i++) {
if (!"localhost".equals(hostnames[i])) return hostnames[i];
}
return hostnames[0];
}
public static String[] getHostNames() {
String localhostName;
try {
localhostName = InetAddress.getLocalHost().getHostName();
} catch (UnknownHostException ex) {
return new String[] {"localhost"};
}
InetAddress ia[];
try {
ia = InetAddress.getAllByName(localhostName);
} catch (UnknownHostException ex) {
return new String[] {localhostName};
}
String[] sa = new String[ia.length];
for (int i = 0; i < ia.length; i++) {
sa[i] = ia[i].getHostName();
}
return sa;
}
I am developing a Facebook application. In this application, I use Java API provided by Google and the application is based on web.
I have the facebook_api_key and facebook_secrete, but how to get the sessionKey?
This code is not web-based:
FacebookJsonRestClient client = new FacebookJsonRestClient(Test.API_KEY, Test.SECRET);
String token = client.auth_createToken();
String url = "http://www.facebook.com/login.php?api_key=";
url += Test.API_KEY;
url += "&v=1.0";
url += "&auth_token=";
url += token;
String strCommand = "C:/Program Files/Internet Explorer/IEXPLORE.EXE ";
strCommand += url;
Runtime.getRuntime().exec(strCommand);
// wait until the login process is completed
// fetch session key
String session = client.auth_getSession(token, true);
......
I want to change it to a web-based one.
Why can't you try this way:
String sessionKey = request.getParameter(FacebookParam.SESSION_KEY.toString());
FacebookXmlRestClient client = new FacebookXmlRestClient(FB_API_KEY, FB_SECRET_KEY, sessionKey);
I also suggest the FaceBook Developer Forum Dicussion and an article describe about generating session keys. I thought it could be helpful to you..
