I have images on my file server which I want to embed into my email.
I can send email with local images like this way
message.addInline("image1", new ClassPathResource("../../static/images/123.jpg"));
but if i want to send email with my file server images, won't work.
message.addInline("image1", new ClassPathResource("http://fileserver.com/images/123.jpg"));
Anybody knows there is a way to do this?
This question is a year old, but I want to contribute for help other people...
Spring have ways to do the job that you want. Take a look in this chapter of the Spring 3x reference. Or Spring2x.
In resume:
You can obtain your image file from file file system of the server. As you can see in the reference:
Resource res = new FileSystemResource(new File("c:/Sample.jpg"));
helper.addInline("identifier1234", res);
Or from a relative path of the classpath of your application:
Resource res = new ClassPathResource("mx/blogspot/jesfre/test/image.png");
But, if you want to send a resource from a file server with a URL, you can do something like #Ralph said:
Url url = new URL("http://fileserver.com/images/123.jpg");
Resource res = new InputStreamResource(u.openStream());
And then, simply add the resource to your message:
helper.addInline("myIdentifier", res);
Hope this help somebody...
The problem is that http://fileserver.com/images/123.jpg is no Class Path Resource.
If you access the image from the file system then file access classes from java.io package.
If you really need to to access the files over http, then you need to download the file first.
Url url = new URL("http://fileserver.com/images/123.jpg");
InputStream is = u.openStream();

I'm testing an API with rest assured, programming language is JAVA, I'm having little issue, the issue is , I have to send an image using rest assured, and it's being sent successfully locally, but when i push it to git , having problem with specifying the path, and all my tests are run on TeamCity , and I get my cucumber report, report as follows
java.io.FileNotFoundException: C:\Users\nameOfUser\Downloads\38250987.jpeg (The system cannot find the path specified)
I hope I have delivered the issue descriptive enough, in case if u have any questions,doubts please do ask your questions, hoping for your help and cooperation, thanks in advance!
the code as follows
public static Response SendAnImage(String prodID,Cookies cookies) {
File file = new File("C:\\Users\\userName\\Downloads\\38250987.jpeg");
System.out.println("is file found ----> "+file.exists());
Response response = given()
.multiPart("file", file, "image/jpeg")
.when()
.cookies(cookies)
.post("/api/product/"+prodID+"/file/false");
return response;
}
You can put your file in src/test/resources folder, then create a new File like this:
File file = new File("src/test/resources/38250987.jpeg");
You cannot refer to local files in your tests. You need to include the picture file to your Git repository, load them as a resource in the test and then use the method in REST-assured that accepts a byte array instead of a file:
multiPart(String controlName, String fileName, byte[] bytes)
This is my first hands on using Java Spring boot in a project, as I have mostly used C# and I have a requirement of reading a file from a blob URL path and appending some string data(like a key) to the same file in the stream before my API downloads the file.
Here are the ways that I have tried to do it:
FileOutputStream/InputStream: This throws a FileNotfoundException as it is not able to resolve the blob path.
URLConnection: This got me somewhere and I was able to download the file successfully but when I tried to write/append some value to the file before I download, I failed.
the code I have been doing.
//EXTERNAL_FILE_PATH is the azure storage path ending with for e.g. *.txt
URL urlPath = new URL(EXTERNAL_FILE_PATH);
URLConnection connection = urlPath.openConnection();
connection.setDoOutput(true); //I am doing this as I need to append some data and the docs mention to set this flag to true.
OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream());
out.write("I have added this");
out.close();
//this is where the issues exists as the error throws saying it cannot read data as the output is set to true and it can only write and no read operation is allowed. So, I get a 405, Method not allowed...
inputStream = connection.getInputStream();
I am not sure if the framework allows me to modify some file in the URL path and read it simultaneously and download the same.
Please help me in understanding if they is a better way possible here.
From logical point of view you are not appending data to the file from URL. You need to create new file, write some data and after that append content from file from URL. Algorithm could look like below:
Create new File on the disk, maybe in TMP folder.
Write some data to the file.
Download file from the URL and append it to file on the disk.
Some good articles from which you can start:

I have an xslt file stored in the folder Project/tools. (I'm using Netbeans IDE.)
I try to access this file in my code, but at run time, I get an AccessControlException: access denied.
The code is:
java.net.URI xsltURI = new java.net.URI(myUtil.getUri("xsltFile.xslt"));
Transformer transformer = factory.newTransformer(new StreamSource(new File(xsltURI)));
The myUtil instance must be used to access the URI for reasons not important here. I printed its output, and it correctly gives the relative path of the file.
I have tried to prefix the relative path with file:/// and file:///[fulldomain], but in each of these cases, it actually tries to access a hard drive on the server, even though I did not give a drive name anywhere. (!) It tries to access C:[relative-path], which isn't even where the file is anyway.
If I omit file:/// then I get that the URI is not absolute, and if I just give the full web address of the file I get a NullPointerException.
Any help at all would be greatly appreciated.
UPDATE: Following my comment below, my code resembles
java.net.URI xsltURI = new java.net.URI("https://host" + myB2U.getUri("xsltFile.xslt"));
java.net.URL xsltURL = xsltURI.toURL();
java.net.URLConnection myConnection = xsltURL.openConnection();
myConnection.connect(); //AccessControlException: access denied ("java.net.SocketPermission"...
java.io.InputStream xsltStream = myConnection.getInputStream();
Transformer transformer = factory.newTransformer(new StreamSource(xsltStream));
Is there something obvious that is wrong?
The file:// protocol tells Java to use file access to open the stream. If you don't want file access you should use a different protocol such as http://.
If you're using a relative path the URI should look something like file://./My/Relative/Path. The 3rd slash means that it is relative to the root.
From what I've gathered, I'm supposed to instantiate a URL object with the path of the file. From there, I'm supposed to be able to initialize a URLConnection from the URL. After I call the URL's connect() method, I'm supposed to be able to obtain an InputStream by calling the getInputStream() method.
Until now I did saving image into the webapp directory and its path into database.
But now am trying to save the image outside of the webapp so that if I deploy my new war files then my old files folder will not be deleted.
From my below code my image file is correctly saving into the specified folder outside of the webapp but i don't know how to retrieve that image into my jsp page.
I tried like this
<img src="www.myproject.com/struts2project/files/smile.jpg/>"
but this is wrong. I am not getting my image to be display into my jsp page.
Below code is working fine for uploading image into absolute path but my problem is how to retrieve that image?
`fileSystemPath= "/files";
try{
File destFile = new File(fileSystemPath, thempicFileName);
FileUtils.copyFile(thempic, destFile);
String path=fileSystemPath+"/"+thempicFileName;
theme=dao.getThemeById(themId);
theme.setThemeScreenshot(path);
theme.setThemeName(theme.getThemeName());
theme.setThemeCaption(theme.getThemeCaption());
dao.saveOrUpdateTheme(theme);
}catch(IOException e){
e.printStackTrace();
return INPUT;
}`
Kindly help me...
I hope I'm being clear on what I need, let me know if I am not and I'll try to explain in another way.
As you say . . . this question describes what you need to do. I guess what you need to know is how to best achieve this with struts 2. Here's what's going on.
In your tag:
That url is being routed to your struts 2 application. Correct? The context is "struts2project".
One of the solutions offered by the referenced question is to use Tomcat's ability to serve static requests and configure tomcat to know about this other document root that holds your images. I think this is a great solution.
If you want to keep it inside of struts2, I think you're best option is to use a dedicated "image streaming from that other place" action that get's an InputStream to the image, then uses the Struts2 Stream Result result type. That result type lets you specify an adhoc InputStream. It also helps you set the appropriate headers. Note, the header values on that documentation page are for downloading the file, so you don't want those values. They would force the browser to open a save as dialog for the image, I think.
You are already using absolute paths, just use a location outside of your web application:
String destinationDir = "/path/to/my/directory/";
File file = new File(destinationDir + item.getName());
I am creating a Swing application with a JEditorPane that should display an HTML file named url1.html stored locally in the page folder in the root folder of the project.
I have instantiated the following String object
final String pagePath = "./page/";
and in order to be displayed by the JEditorPane pane I have created the following URL object:
URL url1 = new URL("file:///"+pagePath+"url1.html");
However when the setPage() method is called with the created URL object as a parameter:
pagePane.setPage(url1);
it throws me a java.io.FileNotFoundException error.
It seems that there is something wrong with the way url1 has been constructed. Anyone knows a solution to this problem?
The solution is to find an absolute path to url1.html make an object of java.io.File on it, and then use toURI().toURL() combination:
URL url1 = (new java.io.File(absolutePathToHTMLFile)).toURI().toURL();
Assuming if the current directory is the root of page, you can pass a relative path to File:
URL url1 = (new java.io.File("page/url1.html")).toURI().toURL();
or
URL url1 = (new java.io.File(new java.io.File("page"), "url1.html")).toURI().toURL();
But this will depend on where you run the application from. I would make it taking the root directory as a command-line argument if it is the only configurable option for the app, or from a configuration file, if it has one.
The another solution is to put the html file as a resource into the jar file of your application.
To load a resource from the classpath (as khachik mentioned) you can do the following:
URL url = getClass().getResource("page/url1.html");
or from a static context:
URL url = Thread.currentThread().getContextClassLoader().getResource("page/url1.html");
So in the case above, using a Maven structure, the HTML page would be at a location such as this:
C:/myProject/src/main/resources/page/url1.html
I would try the following
URL url = new URL("file", "", pagePath+"url1.html");
I believe by concatenating the whole string, you are running into problems. Let me know, if that helped
