I have some epub files that I saved to android internal storage. I have been using folioReader library to display this files but it keeps telling me the path destination is null.
So, I checked android studio's Device File Explorer and I found the files this location: /data/data/packageName/files/FileName
Am using this code to get path:
try{
String path = getFilesDir().getPath() + "/" + fileName
folioReader.openBook(path);
Log.i("Path:", path);
} catch (Exception e){
e.printStackTrace();
}
}
It returns this path on my log cat:
/data/user/0/packageName/files/fileName
There seems to be a difference in the locations paths.
So, my question is this: how do I get path to this location?
/data/data/packageName/files/FileName
private String getFilePath(){
ContextWrapper contextWrapper = new ContextWrapper(getApplicationContext());
File filePath = contextWrapper.getFilesDir();
File file = new File(filePath,"fileName" +"*/*");
return file.getPath();
}
here 'filePath' contains '/data/data/packageName/files/' location
then joining it with '/fileName' gives the whole storage path of that file
*/ * tells that 'fileName' can be of any file type

I wanted to know how I can get the absolute path of a file which is inside my project not in the application running.
For example this one:
C:\Users\Mr\Documents\Example\org.xtext.example.mydsl\src\example.txt
I have tried with paths like:
val file = new File("relative path");
val absolutePathString = file.getAbsolutePath();
or
System.getProperty("user.dir");
But all of them retrieves me Eclipse's path and not my project's path.
Thanks for the help!
There does not need to be a file. Assuming you have a default eclipse with default filesystem and talk about a file in a project you may have a look a at these
public void doit(Resource r) {
URI uri = r.getURI();
if (uri.isPlatformResource()) {
IFile file = ResourcesPlugin.getWorkspace().getRoot().getFile(new Path(uri.toPlatformString(true)));
file.getLocation();
file.getLocationURI();
file.getRawLocation();
file.getRawLocationURI();
}
}
I have two packages: webserver and utils which provides assets to webserver.
The webserver needs access to static files inside utils. So I have this setup:
utils/
lib/
static.html
How can I access the static.html file in one of my dart scripts in webserver?
EDIT: What I tried so far, is to use mirrors to get the path of the library, and read it from there. The problem with that approach is, that if utils is included with package:, the url returned by currentMirrorSystem().findLibrary(#utils).uri is a package uri, that can't be transformed to an actual file entity.
Use the Resource class, a new class in Dart SDK 1.12.
Usage example:
var resource = new Resource('package:myapp/myfile.txt');
var contents = await resource.loadAsString();
print(contents);
This works on the VM, as of 1.12.
However, this doesn't directly address your need to get to the actual File entity, from a package: URI. Given the Resource class today, you'd have to route the bytes from loadAsString() into the HTTP server's Response object.
I tend to use Platform.script or mirrors to find the main package top folder (i.e. where pubspec.yaml is present) and find imported packages exported assets. I agree this is not a perfect solution but it works
import 'dart:io';
import 'package:path/path.dart';
String getProjectTopPath(String resolverPath) {
String dirPath = normalize(absolute(resolverPath));
while (true) {
// Find the project root path
if (new File(join(dirPath, "pubspec.yaml")).existsSync()) {
return dirPath;
}
String newDirPath = dirname(dirPath);
if (newDirPath == dirPath) {
throw new Exception("No project found for path '$resolverPath");
}
dirPath = newDirPath;
}
}
String getPackagesPath(String resolverPath) {
return join(getProjectTopPath(resolverPath), 'packages');
}
class _TestUtils {}
main(List<String> arguments) {
// User Platform.script - does not work in unit test
String currentScriptPath = Platform.script.toFilePath();
String packagesPath = getPackagesPath(currentScriptPath);
// Get your file using the package name and its relative path from the lib folder
String filePath = join(packagesPath, "utils", "static.html");
print(filePath);
// use mirror to find this file path
String thisFilePath = (reflectClass(_TestUtils).owner as LibraryMirror).uri.toString();
packagesPath = getPackagesPath(thisFilePath);
filePath = join(packagesPath, "utils", "static.html");
print(filePath);
}
To note that since recently Platform.script is not reliable in unit test when using the new test package so you might use the mirror tricks that I propose above and explained here: https://github.com/dart-lang/test/issues/110
I'm using FileReference to open a file, but I can only get the file name that the user selected, not the full path. Can I get the complete file path, or is there a security issue? Or should I use another approach?
private function openClicked(e:MouseEvent):void {
var fr:FileReference = new FileReference();
fr.browse();
fr.addEventListener(Event.SELECT , fileSelected);
}
private function fileSelected(e:Event){
trace ("file sel " + e.target.name);
//do stuff
}
The FileReference class does not allow that. You'll need to use the File class instead.
This is my first question here, i hope i'm doing it right. Sorry for my bad English in advance :)
I am using JSF 2.0 (Eclipse IDE) and i'm trying to generate some PDF files using Apache FOP 1.0.
I was able to make simple PDF files using instructions on Apache Fop site , but i can't insert any image from my application folder. My folder structure is like this:
In my application WebContent i have (among else)
pdf_transform/xslt/transformFile.xsl, and
pdf_transform/xslt/logo.jpg
In transformFile.xsl i have
<fo:block><fo:external-graphic src="url('logo.jpg')"/></fo:block>
but when i clik 'showPDF' button in my servlet, i get PDF file without image (everything else is there), and this messages in console:
SEVERE: The Source that was returned
from URI resolution didn't contain an
InputStream for URI: logo.jpg Nov 18,
2010 5:16:49 PM
org.apache.fop.events.LoggingEventListener
processEvent SEVERE: Image not found.
URI: logo.jpg. (No context info
available)
I tried to use 'logo.jpg' instead of url('logo.jpg'), putting image on various places inside WebContent folder and using different navigation("./logo.jpg") but it didnt work.
It works fine if i set absolute path (for example "d:/fop/images/logo.jpg") but i need resurces whitin my application.
While searching, i found that this is related to fopFactory.setURIResolver() and/or userAgent.setBaseURL(). Tried something with that, but didnt succeed.
I am new to both JSF and FOP, and this image situation has been bothering me quite a while. Can someone help me with this, or at least direct me to some tutorial on "how to configure FOP for relative path use"?
EDIT: I don't want any absolute paths and app should work independently of its location on computer (to be publishable). My search tells me it has something to do with configuring FOP, but i don't know how to do it :)
Thanks in advance.
P.S. This is method which is called to display PDF:
public void printExchangeRateList(ActionEvent event) {
BufferedOutputStream output = null;
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
HttpServletResponse response = (HttpServletResponse) externalContext.getResponse();
String path = externalContext.getRealPath("/");
try {
response.reset();
response.setHeader("Content-Type", "application/pdf");
output = new BufferedOutputStream(response.getOutputStream(), 10240);
File xsltfile = new File(path+"/pdf_transform/xslt/transformFile.xsl");
FopFactory fopFactory = FopFactory.newInstance();
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
try {
Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, output);
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer(new StreamSource(xsltfile));
Source src = new DOMSource(makeXML()); // my method
Result res = new SAXResult(fop.getDefaultHandler());
transformer.transform(src, res);
} finally {
if (output != null) output.close();
/*try {
out.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}*/
}
} catch (Exception e) {
// TODO Auto-generated catch block
}
facesContext.responseComplete();
}
i found solution to my problem. I thought i tried that, but it seems i made some little mistake back then. Anyway, with the following code
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
String basePath = externalContext.getRealPath("/");
FopFactory fopFactory = FopFactory.newInstance();
fopFactory.setBaseURL(basePath);
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
foUserAgent.setBaseURL(fopFactory.getBaseURL());
Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, output); // for some output
you can access your images (and other resources) from your xslt file using relative path starting from your application's WebContent folder. In my case, i can access logo.jpg like this
<fo:external-graphic src="url('pdf_transform/xslt/logo.jpg')"/>
Took me time to figure out this, i don't get it why no examples with such basic thing on the net (or i can't find them :)
Note: In FOP 2.0 there is no setBaseURL() method. Instead you pass the base URL as a parameter to FopFactory.newInstance(). Many of the other setters have been moved to FopFactoryBuilder.
If you have access to the web url for the pictures you can use that as well when generating reports, ie http://localhost/images/logo.jpg .
But while I still had images locally on the web server, I included the path to the application in the XML file and used it like this:
<xsl:variable name="base_path" select="base-path"/>
<xsl:variable name="logo" select="companies/company/logo"/>
<fo:external-graphic src="url({$base_path}{logo})"/>
Where the XML structure might be something like this:
<?xml version="1.0" encoding="UTF-8"?>
<base-path>/path/to/app/</base-path>
<companies>
<company>
<logo>images/company1.jpg</logo>
</company>
<company>
<logo>images/company2.jpg</logo>
</company>
</companies>
I had the same problem and tried this solution:
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
Request request = RequestCycle.get().getRequest();
//sort of a hack to find the path to the files that are in /img folder.
String baseUrl = request.getUrl().getProtocol()+"://"+request.getUrl().getHost()+":"+request.getUrl().getPort();
foUserAgent.setBaseURL(baseUrl);
Then, on XSL I used:
<fo:external-graphic src="/img/image.png" />
To test if this is working, you should be able to see the image on protocol://link:port/img/image.png
i have created a resource file "Resource.resx" in my project and added some values against some keys(string values) now when i try to access the value i get the following error...
Could not find any resources appropriate for the specified culture (or the neutral culture) on disk. baseName: Resource locationInfo: fileName: Resource.resources
im accessing the resource.resx by following code
string key = "Home";
string resourceValue = string.Empty;
string resourceFile = "Resource";//name of my resource file Resource.resx
string filePath =System.AppDomain.CurrentDomain.BaseDirectory.ToString();
ResourceManager resourceManager = ResourceManager.CreateFileBasedResourceManager(resourceFile, filePath, null);
resourceValue = resourceManager.GetString(key);
im using mvc.net...
plz help
Why don't you use the class automatically generated by Visual Studio when you added the Resource.resx file (Resource.Designer.cs). This way you don't need to write all the code you wrote.
// assuming you've added a Home key in the resource file
string resourceValue = Resource.Home;
