I am interested in seeing some PHP class with some working examples making trades on the Bitshares DEX. I found https://github.com/carlo-fontanos/bitshares-api-php but it requires a running full node.
I don't want to have to run Bitshares, but want to connect to a node that is running somewhere else. If this code does not exist anywhere, I would be interested in building it. any help please
You can update RPC endpoint URL to match your requirement.
You can see that in index.php line 9.

I am working on a JCA implementation of Jackrabbit with a custom JAAS login module. The idea is to integrate Apache Shiro authentication and authorization via the login module, using a RepositoryLoginContext that simply furnishes user name and password from a Shiro token for the callback functions.
(I have only a small number of users, which are configured with a shiro.ini file.)
All the pieces seem to fit until I try connecting to the repository. One attempt is
SimpleCredentials userJCACredentials = new SimpleCredentials(username,shriroUserCreds.getPassword().toString());
but I cannot seem to find a build path JAR that makes it happy. The Jackrabbit API docs have me flummoxed. If I look for SimpleCredentials, I get a Day Software page (!) however if I look for CryptedSimpleCredentials, I get an Apache page. Thinking that perhaps only the crypted version can be used with the resource adapter, I tried changing to that but run into the same problem with
connInfo = new JCAConnectionRequestInfo(cryptedCreds,workspaceName)
which only wants SimpleCredentials in the first argument. I keep finding dead ends in the API, such as JCAConnectionRequestInfo(Credentials creds, String workspace). If you click on the Credentials link, it times out. Another gem is one of JCAManagedConnectionFactory's constructors, which has text about IBM Websphere (!!).
I tried writing my own class (based onsimple credentials) implementing Credentials interface and the error with
new JCAConnectionRequestInfo(cryptedCreds,workspaceName)
turned into inability to resolve javax.jcr.Credentials. With a Jackrabbit installation, the javax.jcr path does not exist (at least for the resource adapter version).
Failing to make any sense of the foregoing, I tried a second approach.
repoParameters.put("homeDir",ARCHIVE_REPO_DIR);
repoParameters.put("configFile",ARCHIVE_REPO_CONFIG);
repoMan = JCARepositoryManager.getInstance();
repo = repoMan.createRepository(repoParameters);
The last line, using a Map argument, was prompted by Eclipse auto completion, in conflict with the documentation showing createRepository( string, string ). In any case, an error about resolution of javax.jcr.Repository appears. Back to the same stuff.
I've explored every bottom up path in the libraries to get a Session. It seems to be impossible, ultimately failing for a non-existent definition.
Looking the source code, I've assembled the following
JCAManagedConnectionFactory mcf = new JCAManagedConnectionFactory();
mcf.setConfigFile(...);
mcf.setHomeDir...);
try {
mcf.setLogWriter(lpw);
connectionFactory = mcf.createConnectionFactory();
} catch (ResourceException rex) {
logger.error("client session failed to create connection factory");
logger.error(rex);
} finally {
success = false;
}
if (success) {
repo = (RepositoryImpl) connectionFactory;
session = repo.login( needs Credentials Here );
}
The login call needs Credentials and a workspace name. If the login is going to be handled by JAAS, I'd expect to find a login() with no arguments wherein the JAAS login would take over.
I used jackrabbit a couple of years ago in a project and had some small success with it but then moved from jackrabbit to modeshape which is an alternative implementation of the JCR (JSR-283. This is a very active project in which I have had a (very small) involvement. Development continues at a great rate with new releases regularly coming out.
I started with version 2.8 which wasn't bad but the 3.0 release was an almost complete rewrite with a focus on performance and was a delight to use. 4.0 is now in the last stages of being released.
The changeover from Jackrabbit (2.2.7) to Modeshape (2.8.1) was relatively painless with most of the effort in setting up the configuration and runtime.
I'm not saying you won't find problems like you are seeing in Jackrabbit but if you ask a question in the modeshape forums you will get a good answer and plenty of ongoing help.
Lessons Learned:
Integrating Shiro was not a great idea, but not at all because of Shiro. The JCA requires JAAS login. "Integrating" Shiro requires enough understanding of JAAS that I might as well just adopt JAAS and be done with it. But getting further along, I realized that it was fine. There are larger issues ahead.
JAAS is, well, JAAS. I was far from able to breeze through it and pick up what I needed although I have gotten pretty far. The answer to the last dilemma in the post is simply that the login method called is not found in the JCA, it's found in the JAAS login module that you code and "register" through the Geronimo admin console by creating a new security real for you application. A large part of the JAAS learning curve is that it the model is very abstract. There is no "JAAS in a nutshell for Geronimo" to enlighten would-be programmers. Another part is that it is so widely used, information specific to everything but what I'm doing seems ubiquitous. It isn't surprising because web apps are by far it's greatest usage. And following that, it is not really surprising to find a JAAS login module with Jackrabbit as the JCR was envisioned for web content.
It turns out that burrowing into JAAS, though enlightening, was a complete waste of time.
After putting the effort into getting JAAS together, I finally had a Jackrabbit Session Handle. I immediately put it to work on a utx wrapped piece of old code.
Things stopped cold here. None of my old code worked, starting with getRootNode(). I let Eclipse show me the possible methods for a session handle and I tested each one. The list of those that work is short. Some UTX related stuff works, as does "equals", hasCapabilty, isLIve, and little else. Sixty plus methods of the Session Handle cannot work. THIS MEANS THAT THERE IS NO WAY TO GET A NODE. WHICH MEANS YOU CANNOT DO ANYTHING USEFUL WITH THE JCA.
As to my original question, I will say that at one point the JCA probably did work. After all, no one would code all that stuff just to have it lined out. And I will also say that whenever the code was modified to use JAAS, it was badly broken and rendered useless.
This really is a soapbox moment. The amount of time I invested in this was significant. One reason I wanted to use Jackrabbit was that it could run in the same JVM as my application, in Geronimo. I can understand documentation that isn't up to par and other realities of open source. But I could only speculate about how this happened, and the alternatives are all pretty negative. I smelled a rat earlier but said nothing.
One thing is clear. The JCA (and for all I know, the rest of the Jackrabbit project) has no business being touted as an Apache Project. It is a disservice to their name and an extreme disservice to developers who've been led down a dead end path.
I am not sure how to go about it, but I want to bring this to the attention of the Apache foundation if for no other reason than preventing anyone else from going through this.
I have implemented the file upload functionality with reference to this link
http://www.slideshare.net/mongodb/mongo-db-bangalore-2012-15070802
But the file is not stored into the Gridfs.
I had done some research for the same and also with reference to this blog post
http://php-and-symfony.matthiasnoback.nl/2012/10/uploading-files-to-mongodb-gridfs-2/
But again, unfortunately, I stuck with this issue since last from 15 days
please help.
Please take a look at KnpLabs/Gaufrette and the related KnpLabs/KnpGaufretteBundle
The Gaufrette bundle provides a level of abstraction around file systems and, it helped me get file-oriented operations up and running quickly. I found it very useful, and in fact the Symfony CMS package leverages this bundle. It may help you out as well.
I currently have a website i'm working on that I have taken over from another individual, I dumped his SQL file into my database and everything seems to be ok apart from one thing. Whenever I try to log in to the back end or if I try to go elsewhere, it will add an additional .co.uk to the address bar, making it like so:
From: www.domain.co.uk to www.domain.co.uk.co.uk
I've had a dig in the database but I really can't find anything and i've never faced this issue before, could anyone shed some light on this for me? Maybe just let me know where I could look within the database to identify the problem, many thanks.
Take a look at the .htaccess file in the root folder, which is hidden and may contain rewrite rules.
Also, I recommend you use this plugin for migrations:
http://wordpress.org/extend/plugins/wp-migrate-db/
I use it whenever I move from localhost to a live site and vice versa. It will also ensure your widgets are preserved, since doing a find replace will cause the object serialisation syntax WordPress uses to break.
After migrating, you need to visit Settings > Permalinks so the .htaccess file can be updated according to the new URL for rewrites.
i am trying to figure this out for a long time now, but so far no luck, maybe somebody can help me.
I have a 2.2.2 cakephp installed on my computer (localhost) and everything works perfectly. But now i want that same project to be online on remote server. I upload everything, set mysql path but i get a blank page when trying to access the site.
If i upload a fresh cakephp it works, but my project doesnt. The debug is set to default, think that should be 2? I also deleted files in cache/tmp, but still no errors or anything, just blank page.
Any info would be helpful, thank you.
I hate when that happens :). Usually it does if there is an error somewhere and you can't see it because the errors are turned off, so you should call phpinfo() and see if display_errors is on. Changing the debug mode doesn't work every time since display_errors is set from php.ini.
Unfortunately, if this is the problem and you don't have access to edit the php.ini file, you might need to ask the hosting provider to change it and restart the php service.
You can also try this: error_reporting(E_ALL)
I uploaded changes to my cakephp website and discovered that all actions for a particular controller returned a blank page. I discovered what the error was and was able to reproduce it with another controller.
The problem was that in the first line of my controller file I had a space before the opening php tag.
One space cost me hours.
Just uploading all files won't cut it. Make sure you work through this checklist:
First and foremost, check the error log file located under app/tmp/logs/error.log, this usually holds some very good pointers as to what is wrong.
Make sure you have uploaded the app/Config/database.php file with the proper details. Local installs usually have user root without password. Online servers (obviously) do not!
To that extent, also make sure you actually have a database with your hosting provider (either your host sent you the info or you need to create it yourself using their control panel).
Make sure you also uploaded all .htaccess files (the one under the root directory and /app and /app/webroot), some FTP programs don't show this "hidden" file by default.
If all else fails, contact your hosting provider for further support as they usually have access to more verbose server logs that can also hold clues.
The real problem was only the coding I used in notepad++. All my files were encoded with UTF-8, but they should have been UTF-8 without BOM. After I changed it to UTF-8 withot BOM, everything started to work perfectly.
I am developing a basic yet highly customized CRM for a small training centre which has the ability to store student records and also send emails to them. I'm using SwiftMailer following this excellent tutorial in CakePHP to accomplish the sending part.
Of course, students are sometimes going to reply to emails and I'd like to retrieve them within my CRM and store them along with the student record.
However, I cannot find a single reference to doing this. I've tried the following Google searches: "receiving email cakephp" , "retrieving email cakephp" and even "email client cakephp" but all of these queries give results relating to sending mail rather than receiving it -- very frustrating!
Finally, I broadened my search to non-cake solutions and found someone recommending a library called ezComponents. It doesn't seem to have had any active development for about a year, but it includes an email receiving class which is exactly what I want. Unfortunately, I have no idea how to add this to CakePHP and the only post I've been able to find on the entire web on the matter doesn't exactly go into much detail. It's certainly not a step-by-step tutorial on using ezComponents on CakePHP like the SwiftMailer tutorial I mentioned above.
I also found a class on Google Code called php-imap which looks like it would do the job but, again, I haven't the slightest clue how to get it working happily in Cake like SwiftMailer is.
I realize that I may have to learn how to package classes for use in Cake by myself but I'm asking this question first on the off-chance that there is already a Cake-friendly solution to this problem that I just haven't realized :-)

Thanks to everyone for your answers, but I've been doing some more searching and it looks like the solution is actually incredibly simple.
Basically, with the help of a plugin, I can set up the mail server in databases.php as a datasource and then write a Model and Controller to interact with it.
Here's the example I found: https://github.com/kvz/cakephp-emails-plugin
Edit: the repo has been deprecated and is now available at https://github.com/kvz/deprecated/tree/cakephp-emails-plugin
You will want to pipe your email to PHP and use stdin:// to read the contents of the email and add the e-mail to your database.
I've done this with cake and the simplest way is to make a Cake console application to handle the parsing. Also using cpanel's account level filtering to generate the pipe is really simple.

http://www.evolt.org/incoming_mail_and_php
Sounds like you want to include SwiftMailer as a Cake plugin, amirite?
http://book.cakephp.org/view/1111/Plugins
-- if you want to package it yourself. Otherwise, a cursory search of the Bakery yielded this result:

Hopefully it will at least get you pointed in the right direction. HTH. :)
