JAVA Question: getResourceAsStream()

in CFML, how can I get to getResourceAsStream()?

cl = createObject(“java”, “java.lang.Class”);

dump(cl);

cl = createObject(“java”, “java.lang.ClassLoader”);

dump(cl);

both output
java.io.InputStream getResourceAsStream(java.lang.String)

​But when I do this I get an error

myR = cl.getResourceAsStream(variables.json);

dump(myR);

​I need to load a file and kept it’s mime type​

from Java class that I am passing file to

JsonObjectParser parser = new JsonObjectParser(jsonFactory);
GenericJson fileContents = parser.parseAndClose(
credentialStream, OAuth2Utils.UTF_8, GenericJson.class);
String fileType = (String) fileContents.get(“type”);
if (fileType == null) {
throw new IOException(“Error reading credentials from stream, ‘type’
field not specified.”);

I don’t think that’s quite what you want to do.

getResource would load a file from a classpath or jar… not from a
variable. If you want to pull a file in as a stream you want something
else.

You’d get the classloader from an instantiated class, or pull the system
class loader. (You probably wouldn’t create one)

I.e. if you want to pull a file from the same package as your
JsonObjectParser class:

<cfset obj = createobject(“java”,
“your.JsonObjectParser”).init(jsonFactory) />
<cfset stream = obj.getClass().getResourceAsStream(“variables.json”) />

would load your/variables.json from the same location as JsonObjectParser.

More likely you want something like
<cfset stream =
createobject(“java”,“java.io.FileInputStream”).init(ExpandPath(“./variables.json”))
/>

fileContents is populated by your parser… not by the stream… If I’m
reading your code properly.

What should fileContents.get(“type”) return?

Based on your code, fileContents.get(“type”) isn’t the mime-type of the
file, it’s the value of the “type” key within the structure represented in
your json object inside your file.

i.e. the file probably has
{
“type”: “something”,

If by chance what you are talking about is authentication for the Google
API using the JSON credentials file (just a wild guess), here’s what I do
(note I use Mark Mandels tremendously useful class loader, so replace the
local.objLoader with a createObject if you’ve got your classes in the
global classpath):

variables.HTTP_Transport =
local.objLoader.create(“com.google.api.client.http.javanet.NetHttpTransport”).init();
variables.JSON_Factory =
local.objLoader.create(“com.google.api.client.json.jackson2.JacksonFactory”).init();
variables.WebmasterScopes =
local.objLoader.create(“com.google.api.services.webmasters.WebmastersScopes”);
variables.GoogleCredentialBuilder =
local.objLoader.create(“com.google.api.client.googleapis.auth.oauth2.GoogleCredential$Builder”)
.setTransport(variables.HTTP_Transport)
.setJsonFactory(variables.JSON_Factory)
.build();
variables.keyFile = ‘/some/absolute/path/to/the/credentials.json’;

local.keyFile = createObject(“java”,
“java.io.File”).init(variables.keyFile);
local.keyInputStream = createObject(“java”,
“java.io.FileInputStream”).init(local.keyFile);
local.credential = variables.GoogleCredentialBuilder

.fromStream(local.keyInputStream,variables.HTTP_Transport,variables.JSON_Factory)

.createScoped(variables.Collections.singleton(variables.WebmasterScopes.WEBMASTERS_READONLY));
local.keyInputStream.close();

So you get the File-Object and open the InputStream on it, close it when
you’re done and you’re all set. As far as I understand that is. Hope that
helps :slight_smile:

Kind regards

Markus
