java - Enumerate all files of certain type from resources -


I have a JAR file that contains the resource section of my Jeanelpi file I There are a lot of images in subfolders

The user should be able to replace this jar file later / enable / add / remove images.

There is a way to calculate all the files from the resources, with the help of the .if files as the file extension or even better "images / * .gif" a pattern To specify (so I just get the picture which "pictures" as their original directory).

The second option would be to write a text file that shows the file structure. In this way you can run through the line through the image through the image, but it will mean that you have to update two places and it is not very user-friendly.

Yes, you just count the files inside move to grab the jar directory: < Pre> public string [] getFiles () throws IOException {of ArrayList & lt; String & gt; List = New Arrestist & lt; String & gt; (); & Lt; JarEntry & gt; Ents = new Array list & lieutenant; Greentree & gt; (); Calculation & LT; JarEntry & gt; E = null; Url jarap = found place (); If (jarp! = Null) {jar = jarp.getProtocol (). Equal ignoreCase ("jar")? Zarp: New URL ("Jar:" + jarp.toString () + "! /"); Jarfile garg = null; try {Jarf = AccessController.doPrivileged (New PrivilegedExceptionAction & LT; JarFile & gt; () {@Override public JarFile runs (throws Exception {JarURLConnection Conn = (JarURLConnection) jar.openConnection ()); conn.setUseCaches (false); return Conn.getJarFile ();}}); } Hold (PrivilegedActionException Pre) {Logger.getLogger (LicenseLoader.class.getName ()) Log in (Level.SEVERE, null, pre). } E = jarf.entries (); While (e.hasMoreElements ()) {JarEntry je = e.nextElement (); If (! Je.isDirectory ()) {ents.add (j); }} {JarEntry ENT: for father} {if. (Ent.getName () startsWith (path)) & amp; (ent.getName () endsWith (".gif")) {string name = ENT GetName () Replace (pathname, ""); List.add (name); }}} Return list. Arrow (new string [list.size ()]); }

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
