I have a strange problem with oracle apex when updating images or css.
The setup is APEX 4.2.6 in web logic.
The i.war file has been created so it references a shared folder that developers can upload and change.
The change enabled the designers to reference images as normal in CSS due to substitution variables not allowed in external files.
I can then reference an image with say the following path ;
/i/mycompany/images/logo.png
This works great, then I change the logo and overwrite file.... Apex now returns a broken image ( but the HTTP response code is still 200) - weird.
If I save the file as logo2.png and then reference all is fine.
It must be cache somewhere , the drastic measure is I'm going to see if bouncing web logic hosted i.war helps , but I this wouldn't be a great solution for each change :).
In the past with images hosted in the workspace I have purged the apex files tables, but like i say these files are outside on a file system.
Any Ideas thoughts out there from the APEX community.
Cheers

This suppose to be a simple issue; not to be posted as a question in stack overflow!
Following this article: How to: Create Embedded Resources
I had created a new and fresh Form1.vb to test in Visual Studio 2017 community edition.
Added a big testfile.WAV file as a test resource.
Checked the link type is set to default value: "Linked at compile
time" Default Value.
Clean/Build/Rebuild the application.
Still no matter what I do, the result.exe file is so big and reflect the big testfile.wav file size, and can't at any situation find the wav file as a linked resources in separate file in bin\Debug folder!
Tried to alter almost everything everywhere; yet no success!
What I expect is to have both result.exe and testfile.wav in bin\Debug folder separately linked and not embedded.
Looks very weird to me? is it a bug in VS or in app setting?
Thank you so much
Appreciated any hint
Note: What I was trying to reach is to create a different themes for my application, where users can chose the appearance; and my efforts break in the above scenario. It doesn't make sense that result.exe ends in 10s of MB if it will include resources inside it!
TL;DR: If you want it as a loose file then you need to have it as a loose file. Resources are always embedded in the application.
If you add the resource via Project Properties > Resources then it will always be embedded in your application.
If you want it as a loose file then you shall just import it to your project via Add Existing Item and set the Copy to Output Directory property of the item to Copy Always. Then you reference it by doing for example:
Dim WavPath As String = Path.Combine(Application.StartupPath, "yourfile.wav")
Dim WavFile As Byte() = File.ReadAllBytes(WavPath)
Linked vs Embedded only make a difference at design time. Linked resources are still embedded in your application, but at design time you may edit them and can easily add or remove other resources.
Embedded resources however are embedded in a .resx file even at design time, and to edit such resources you have to export them or change them into a linked resource. Embedded resources are mostly used when you need to share the same resources in multiple projects. The resources are then embedded in the .resx file so you only need to copy that and not every included file.
I am building a Java app that uses an SQLite database to hold most of its data. For the end-user, the database would be almost entirely read-only, with very occasional edits. I'll (theoretically) be displaying/distributing it through my GitHub page, so my question is:
What's the best way to load the database into GitHub? (I'm using IntelliJ with DataGrip.)
I'd prefer to be able to update the database when I commit/push, instead of having to overwrite the whole file. The closest question I can find is How to include MySQL database schema on GitHub? but there could potentially be hundreds or thousands of entries, so I can't just rebuild the tables when the user installs the app.
I'm applying for entry-level developer jobs, and this project is going to be my main portfolio piece during job-hunting. I'm trying to make sure it is not only functional but also makes a good impression. Any help is (very) greatly appreciated.
EDIT:
After moving my .db file into the folder connected to GitHub (same level as my src folder) apparently I can now commit/push it with the rest of my files. How do I make sure that the connection from my Java code to the database stays valid once it is loaded onto another user's system? Can I just stick with
connection = DriverManager.getConnection("jdbc:sqlite:mydatabase.db");
or do I need to rework the path?
Upon starting, if your application can't find a corresponding sqlite database file, have it create one. Then do initial load of your tables from either CSV, JSON or XML files.
You can upload these files to Git, as they are text formats.
I'm having trouble with a specific ORM cfclocation not being mapped correctly. Coldfusion is checking in the cfclocation I have provided and then cacheing the mapping in a different location so that when I try to load the entity it can't find the cfc (its looking in the wrong folder).
This is only happening to one of my cfclocations. I have tried the same application on a cf10 server and it worked, and on another cf9 server where it didn't work.
So somehow its getting confused about where the cfc is located and generating a different location.
What I am wondering is how can I debug the process coldfusion is going through to cache the locations? I read the outline on orm's architecture on adobes doc pages and it mentioned coldfusion generating .hbmxml files. Where do I find these? Is there another way I can work out why coldfusion thinks a file is located somewhere else.
(I had another question similar to this which I deleted to post this one as the previous question was asking for a fix, this one is asking how to debug)
UPDATE:
I have turned saveMapping on and am getting the hbmxml files now. I can see that the class name is being generated incorrectly. Is there a way to manually set this? IS there a way to manually tell coldfusion what to map the location as. I have no clue why Coldfusion is mapping the location elsewhere.
Answers to questions below
The entityname, name, and file name are all the same.
The file is located in an area that uses a nameing convention that is the same for all of our applications which are working. In inetpub/resources/applications/[application name]/cfcs/orm.
I can dump out the array of addresses that are sent to cfclocation and it is clearly there. It has to be or the file wouldn't be detected in the first place. The ColdFusion and webroot are in different areas, but as mentioned before this works fine for all our other apps.
I have restarted the application and the ColdFusion service repeatedly while testing different things.
The folder that the hbmxml file specifies does not even exist, and never did.
Rebooting coldfusion has no effect. After messing around by adding additional mappings closer to the specific folder and then removing the mappings I eventually got the app working temporarily on my local site. but as soon as i moved it to another server it didn't work. so it seems like a 99% chance of not working
Wanting to use Orchard 1.7 with Media storage on S3 (as I'm deploying to AppHarbor)
So far I'm looking at the S3 Storage provider But its a bit out of date.
Has anyone done this ? is there a better way to use S3 with the new media manager?
I've got images uploading to s3, but they don't display when I click the folder.
here is the Gist of my updated S3Provider
Missing methods for create file, rename folder, get file, and Get storage path. any help on how to complete these would be appreciated.... however stepping through the debugger in VS this doesn't seem to be the root cause of my displaying images issue above.
Edit
Looks like the file is up loading to s3 but not to the database, due to the GetFile method throwing an error...
Edit 2
Added some code to the Get file method. Now that works; (gist updated) Can up load images. However the thumbnails are still not working, they just come back as empty tags ...Think this is because the media manager is using the Open get method - which is supposed to open a file so you can write a stream to it. Don't know how to achieve this with S3... any ideas welcome
As Part of the AWSSKD NuGet package version 1.5.28.3 you can access a S3FileInfo object. I've used this in my S3 Storage File and updated the S3 Storage provider.
This seem to work, need to do a bit more testing on it.
NOTE: I had to add some code on the GetFile Method to ensure the permissions where set correctly otherwise the updating of thumbnails overwrote permissions on the file.... I'm sure there is a better way to do this.
I'm building an application that needs to download web content for offline viewing on an iPad. At present I'm loading some web content from the web for test purposes and displaying this with a UIWebView. Implementing that was simple enough. Now I need to make some modifications to support offline content. Eventually that offline content would be downloaded in user selectable bundles.
As I see it I have a number of options but I may have missed some:
Pack content in a ZIP (or other archive) file and unpack the content when it is downloaded to the iPad.
Put the content in a SQLite database. This seems to require some 3rd party libs like FMDB.
Use Core Data. From what I understand this supports a number of storage formats including SQLite.
Use the filesystem and download each required file individually. OK, not really a bundle but maybe this is the best option?
Considerations/Questions:
What are the storage limitations and performance limitations for each of these methods? And is there an overall storage limit per iPad app?
If I'm going to have the user navigate through the downloaded content, what option is easier to code up?
It would seem like spinning up a local web server would be one of the most efficient ways to handle the runtime aspects of displaying the content. Are there any open source examples of this which load from a bundle like options 1-3?
The other side of this is the content creation and it seems like zipping up the content (option 1) is the simplest from this angle. The other options would appear to require creation of tools to support the content creator.
If you have the control over the content, I'd recommend a mix of both the first and the third option. If the content is created by you (like levels, etc) then simply store it on the server, download a zip and store it locally. Use CoreData to store an Index about the things you've downloaded, like the path of the folder it's stored in and it's name/origin/etc, but not the raw data. Databases are not thought to hold massive amounts of raw content, rather to hold structured data. And even if they can -- I'd not do so.
For your considerations:
Disk space is the only limit I know on the iPad. However, databases tend to get slower if they grow too large. If you barely scan though the data, use the file system directly -- may prove faster and cheaper.
The index in CoreData could store all relevant data. You will have very easy and very quick access. Opening a content will load it from the file system, which is quick, cheap and doesn't strain the index.
Why would you do so? Redirect your WebView to a file:// URL will have the same effect, won't it?
Should be answered by now.
If you don't have control then use the same as above but download each file separately, as suggested in option four. after unzipping both cases are basically the same.
Please get back if you have questions.
You could create a xml file for each bundle, containing the path to each file in the bundle, place it in a folder common to each bundle. When downloading, download and parse the xml first and download each ressource one by one. This will spare you the overhead of zipping and unzipping the content. Create a folder for each bundle locally and recreate the folder structure of the bundle there. This way the content will work online and offline without changes.
With a little effort, you could even keep track of file versions by including version numbers in the xml file for each ressource, so if your content has been partially updated only the files with changed version numbers have to be downloaded again.
