I'm making a project in Java that loads X3D files and it works great with X3D files that don't contain a URL. But the X3D files that I need to use have URLs contained within them. I'm wondering if there's a way that I can use a JPEG within an X3D file without using imageTexture url='"http//:website.com/album/photo.jpg"'. So I was wondering if I could save the JPEG on my laptop and then put it into the X3D file that way? Or is there another way about doing this?
You need to have a reference to the image file inside the X3D file. The reference can be any URI (URL or local path). The correct way of loading an image is by using the ImageTexture element. The other two elements that are able to load an image in an X3D file is VideoTexture and Inline but I would suggest to use ImageTexture. As Marco13 guessed, if you want to use a local image, instead of providing the URL to the image which is stored somewhere on internet you have to provide the local path to the locally stored image file, e.g. ImageTexture { url ["path/to/image.jpeg"] }

I'm making two Java applications one to collect data, another to use it. The one collecting will be importing a file from the other which will include data and images and will be decrypted.
I'm unsure what filetype to use. So far all of the data is in XML and works great but I need the images and was hoping not to have to rely on giving all the images in a folder with a path reference.
Ideas?
well, I think that the best way is to create your own format (.myformat or .data). This file will be in fact a Zip file that contains your XML file and images.
There is no perfect example writen in java as far as I know. However, here are some examples :
Not in java
The best example is, as #Bolo said, the odt format. Indeed, OpenOffice writes the doc in an xml file, and the images too. All that is wrapped in an odt file.
The .exe file is an other example. The C files and the resources are put in a single file. try to open it with 7-zip, you'll see.
The Skyrim plugins are .esp file that contain the dds, the scripts, the niffs (textures)...
In java
The minecraft texture packs are a zip file that contains a .mcmeta file (the infos) and the textures (.png)
Jar files are like exe.
If both programs are in java you could also go with serialization, which is basically saving an object as a file (suffix will be .ser I think) and then being able to retrieve it. You should google it, even if it won't help right now it is quite good to know about it.
I'd suggest using JSON. Gson is a decent library.
You can embed images as byte arrays.
Save the serialized string in a file with a preferred extension, read it from the second application, de-serialize, and reconstruct images.
You can convert binary image data to text with Base64 encoding and this way you can embed your images in XML. [1]: http://en.wikipedia.org/wiki/Base64
Our project has an image uploading module using Java. While uploading image, if a user uploads an image with an extension of jpg/jpeg/gif/png etc., whatever the extension, we save it with same extension by changing just its name.
But here is one small issue. Suppose the user removes the extension of that image manually (of course it never happens, but let's consider it as example) and uploaded the file, it doesn't have any extension.
Is there any way to find out extension/format after reading that image (like after reading the image using getBufferedImage())?
Here I can't use mimeType as we are taking mime type from user while uploading image itself. The user may upload image without an extension, by selecting the mimeType as "image/jpeg".
There are java libraries like mime-util or jmimemagic that can detect the file type from the pure content.
I am developing a Java project in which i have a sub-module where i need to extract contents [text, image, color] from a webpage and compare it with another webpage. I am planning to use WinHTTrack software for downloading the webpage locally, but the problem is it doesn't save it as HTML. How can i download a webpage with HTML extension using softwares such as WinHTTrack [or just saving the webpage through ctrl+s is enogh.?]. Also i am planning to use HTML Parsers to extract the 3 content types[text, image, color],after downloading the webpage locally. So which parser to go with.?
WEll I use Httrack and it fetches html files as well. You are probably taking winhttrack project file as the only output file, but if you check inside the project directory there are html files (together with images, etc). I would suggest using - http://htmlparser.sourceforge.net/. It is a java library and since your project is a Java project it should be fairly easy to use it. You can also save the whole website locally using org.htmlparser.parserapplications.SiteCapturer (and specify whether resources such as images should be captured as well). Hope it helps.
i am trying to create an android application that saves webpages to use it in offline-browsing, i was able to save the webpage but the problem was in the contents (images, javascripts,..etc), is there a way to do so programmatically, i use eclipse and test my work on an emulator.
hm, I am afraid you should parse html's yourself (I mean do that with a properly lib) and store all resources (css, js, images, videos etc.) too.
s. how it is done in a java crawler: open source crawlers
You will need to search for all images, javascript files, css files, etc... and download them, saving them to the same relative path to the HMTL files - Assuming the html is coded with relative paths (images/image.png) and not absolute paths (http://www.domain.com/image/image.png).
You can pretty easily search the html string for <img, <script, <link etc.. and parse from there - or you can find a 3rd party html parser
I have a WebView on my Android application which loads (WebView.loadUrl()) different local HTML files from phone's internal storage. I would like to include some custom css styles for them.
Now, I could have my app edit every HTML file and add linking reference for the CSS file.
I could also read the file contents, add the CSS linking and use WebView.loadData() to load it.
But is it possible to do this a lot simpler and efficiently?
Note: The HTML files are downloaded from a website. So editing them manually is not possible in this case, but once downloaded they can be edited via the app if necessary.
One possibility (I have not tried this):
WebView.loadDataWithBaseURL(String baseUrl, String data, ..)
takes a baseURL for the document to use to resolve relative URLs. Take a look at the CSS url and construct baseURL so that CSS url will reference local CSS file.
