I'm new to openui5 and i'm trying to understand how the openui5 cache buster works by reading through the documentation. I don't understand where I can find the generated sap-ui-cachebuster-info.json, am I supposed to be able to find it in my server (after build)?? or can I access it and read its content in some way? Am I supposed to see it in the list of files my browser receives in the network tab? Can I read it at all?
'sap-ui-cachebuster-info.json' file is generated on the server and usually located in the server root directory.
it's contains information about the version of the OpenUI5 library in use and the corresponding file names,
file content is not accessible to the client, it is read by the server when serving the library files. You can inspect it using browser development tools

Pyscript allows one to run python inside a web browser. I have two python scripts I wrote that I’d like to use. One way to do this is to copy and paste the python code held in these files directly into the index.html file where the index file is part of a GitHub.io page. If possible however, I would rather load/Import them from a remote location. Currently, they reside in the gh-page branch on GitHub alongside the index.html file.
My question is whether this is possible? Most tutorials show how to load and import a local python file which I don’t want to do.
Update: This is my current attempt which I add to the index.html file:
<py-config>
[[fetch]]
from = "https://github.com/etc/blob/gh-pages/"
files = ["myadd.py"]
</py-config>
When I try this I get the error message:
(PY0001): PyScript: Access to local files (using "Paths:" in ) is not available when directly opening a HTML file; you must use a webserver to serve the additional files. See this reference on starting a simple webserver with Python.
I want to avoid starting a server because this is meant to be client-side only approach with only a dumb file repo at the other end.
There is a solution, and it's very simple, just use the syntax:
<py-script src="mypythonscript.py"> </py-script>
And it will pick up the file from the GitHub directory.
I am using jupyterlite which is JupyterLab distribution that runs entirely in the browser.
However, after clearing the browser history, the files are no more visible.
Please let me know how can I retrieve the *ipynb files from my windows machine.
I have already checked %AppData% and I don't see any *ipynb files.
The files are stored in well... the browser. Specifically in the IndexDB or localStorage. This means that the physical location on the disk will depend entirely on the browser that you use, rather than on the operating system, and will likely be inaccessible (for an average user) without decoding binary blobs.
For example, in Chrome you can check the path to the application data using chrome://version/ (under Profile Path) and in that directory there should be IndexedDB folder. Then you need to find a sub-folder depending on the domain in which you accessed JupyterLite, for example https_jupyterlite.readthedocs.io_0.indexeddb.leveldb, and there you will find a LevelDB database file with .ldb extension and a MANIFEST file (with the pointer to the current version in the CURRENT file. The details of how to extract the blobs are outside of scope for this answer, but have a look at How to access Google Chrome's IndexedDB/LevelDB files?.
However, you can use files from your file system directly in JupyterLite without worrying about in-browser technologies with the jupyterlab-filesystem-access extension which uses File System Access API however this API is not available on Firefox yet.
As noted by #Wayne all of this is still quite experimental (both as in "using the newest browser APIs" and "the team of developers is still figuring way forward, please help by providing kind feedback and contributing").
Here's what I know:
When uploading files given by users, we should put them in a folder
outside the deployment folder. Let me call it D:\uploads.
We should (somehow) add that folder (D:\uploads) as a web app context.
Here's what I did:
I upload my files to the folder D:\uploads.
I tried adding the web app context as it's mentionned here by adding the following row to TOMCAT_DIR/conf/server.xml:
<Context docBase="D:\uploads" path="/uploads"/>
But that doesn't have any effect. When consulting http://localhost:8080/uploads/file.png or http://localhost:8080/uploads I get a HTTP Status 404 error.
So what I want to know:
What did I do wrong ? How can I add my upload folder to Tomcat?
Is there any better approach when it comes to uploading files ?
Because I'm wondering what should I change if I want to deploy my
application to another server where there's no D:\uploads.
Change the docBase attribute. Use D:/uploads (with slash) instead of D:\uploads (with backslash).
When dealing with files in Java, you can safely use / (slash, not backslash) on all platforms.
Regarding the differences you mentioned in the comments when starting the Tomcat from the IDE and from bin/startup.bat: It's very likely when you start the Tomcat from the IDE, it is not using the same context.xml your Tomcat is using. Just review the Tomcat settings in the IDE.
How to store uploaded files is a common topic at Stack Overflow. Just look around and you'll get surprised in how this topic is popular.
If you aren't happy enough in storing your files in D:/uploads or you'll have other servers accessing the files, you could consider storing them in some location in your network. Depending on your requirements, you can have one dedicated server to store your files or just share the folder which contains the files in your current server. The right decision will always depend on your requirements.
I am trying to troubleshoot getting a Data/Service deployed to a live server in Flash Builder with an Air application.
I am using AMF/Zend but provided my own Php file called database.php. I'm trying to find somewhere in the code base where that is referenced, but I can't find anything, other than a link to my php file in the /services folder, which I have no idea how to change to linking to a remote file.
I copied & pasted this text here. It seems the editor seems to format some parts randomly. ;)
I downloaded ZendGdata 1.9.6, extracted it & uploaded it to my site's
root folder ..., which I need for use with Youtube API to get videos onto my site.
I must say I’m new to all this, and so I would appreciate taking this into account.
The library folder is at /ZendGdata/library.
The problem I'm having is Step. 3 when I follow instructions
(http://code.google.com/intl/de-DE/apis/gdata/articles/php_client_lib.html#gdata-installation)
for setting it up for that purpose.
Download the Google Data Client Library files.
Decompress the downloaded files. Four sub-directories should be
created:
demos — Sample applications
documentation — Documentation for the client library files
library — The actual client library source files.
tests — Unit-test files for automated testing.
Add the location of the library folder to your PHP path (see the next section)
One of the suggested locations to add the path, apart from the .htaccess file is in php.ini.
My site is on shared hosting. I have no access to the main php.ini file, but I’m allow to create one if I need one. For Drupal CMS, for some functions, it suffices placing one in the root folder.
I added this line:
include_path=".:/usr/lib/php:/usr/local/lib/php:/home/habaris6/
public_html/site.root.folder/ZendGdata/library";
When I however go to mysite.com/ZendGdata/demos/Zend/Gdata/InstallationChecker.php to test the set up, like is mentioned in the
documentation on Youtube, I get the error:
PHP Extension ErrorsTested No errors found
Zend Framework Installation Errors: Tested 0
Exception thrown trying to access Zend/Loader.php using 'use_include_path' = true.
Make sure you include Zend Framework in your include_path which currently
contains: .:/usr/lib/php:/usr/local/lib/php
SSL Capabilities Errors: Not tested
YouTube API Connectivity Errors: Not tested
So my question is: Is that the correct way to “Add the location of the library folder to your PHP path” ?
I’m a bit mixed up.
Someone was saying the php.ini file is only active in the folder where it is located. If that is the case, which of the ZendGdata folders should have it?
As I said, my purpose is to have a the Zend framework properly set up to allow using Youtube API, something I also yet have to learn to do.
In Youtube API Google group, I was referred here. The documentation coming with the downloaded file & at zend.com pre-supposes, one knows much more than some beginners like me.
Another person said I try placing this
$clientLibraryPath = '/home/habaris6/public_html/site.root.folder/ZendGdata/library';
$oldPath = set_include_path(get_include_path() . PATH_SEPARATOR . $clientLibraryPath);
in mysite.com/ZendGdata/demos/Zend/Gdata/InstallationChecker.php
Whereas everything I had tried before failed, except fot the first test, when I placed the above snippet in the installation checker, I got positive tests for everything:
Ran PHP Installation Checker on 2009-12-09T21:16:08+00:00
PHP Extension ErrorsTested: No errors found
Zend Framework Installation Errors Tested No errors found
SSL Capabilities ErrorsTested No errors found
YouTube API Connectivity ErrorsTested No errors found
Does it mean if I place that snippet in install checker, all scripts needing the library can access it?
If not, please let me know what exactly to place in the self-made php.ini & in which folder(s) it should be.
Should that not work, and I were to use .htaccess files, what exactly, based on the folders mentioned above should be the content & exactly which folders should they be in? I read that the .htaccess files should be placed in each folder. Does it really mean I should place one in each of the ZendGdata folders?
I would be grateful for any guidance enabling me to finally start, after failing to sufficient get responses elsewhere.
Thanks in advance.
It's not necessary to put all the ZendGdata code under your website document root. In fact, as a rule I don't put PHP class libraries in a location that can be accessed directly by web requests, because if there's any way to do mischief by invoking the class files directly, then anyone can do it.
Instead, put libraries outside your document root and then reference them from scripts that are run directly. For example, you could create a directory phplib as a sister to your public_html directory. Then upload the ZendGdata bundle under that phplib directory.
You can set your PHP include path in a .htaccess file. You don't need to create a .htaccess file in every directory, because the directives in any .htaccess file apply to all files and directories under the directory where the .htaccess resides. See http://httpd.apache.org/docs/2.2/howto/htaccess.html for more information.
So I would recommend creating a .htaccess file at /home/habaris6/public_html/site.root.folder containing the following directives:
<IfModule mod_php5.c>
php_value include_path ".:/usr/local/lib/php:/home/habaris6/phplib/ZendGdata/library"
</IfModule>
See http://php.net/manual/en/configuration.changes.php for more info on this.
Note that this assumes your webhosting company allows you to use .htaccess files, and that they allow you to use the php_value directive in .htaccess files. Enabling these options is an Apache configuration and they could have their own policies against that for reasons of performance or security. You should contact them for this answer; no one on the internet can answer questions about your hosting provider's policies.
If you choose to use the set_include_path() PHP function to append a directory to your runtime include path, you need to do this in each file that serves as a landing point for a web request. That is, if you permit a request to be made directly to foo.php then you need to add the code to foo.php. Any files or classes subsequently included by foo.php use the include path you defined.
Note also that whatever method you use to define the include path, it has to take effect before your script tries to load any PHP class files via the include path. The .htaccess method should accomplish this, and if you use the code method you just have to put the code high enough in your PHP script.
I don't use the method of creating a custom php.ini file under each directory within your site document tree. That's a new feature of PHP 5.3.0, not supported by earlier versions of PHP. If you're using Apache you should just use .htaccess for the same effect.
