• How to set up jndi.properties for DataStore?

  - by FarmBoy

  I'm struggling to set connect a Java program to MySQL using JPA/Hibernate. I'm currently getting the following error when I try to call createEntityManagerFactory(): [main] ERROR org.hibernate.connection.DatasourceConnectionProvider - Could not find datasource: java:jdbc/myDataDS javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:645) at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:288) at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:325) at javax.naming.InitialContext.lookup(InitialContext.java:392) at org.hibernate.connection.DatasourceConnectionProvider.configure(DatasourceConnectionProvider.java:75) Googling seems to indicate that I need a jndi.properties file in META-INF in my classpath, but I can't seem to find any information about what that file should contain in my case.

• HTG Explains: The Linux Directory Structure Explained

  - by Chris Hoffman

  If you’re coming from Windows, the Linux file system structure can seem particularly alien. The C:\ drive and drive letters are gone, replaced by a / and cryptic-sounding directories, most of which have three letter names. The Filesystem Hierarchy Standard (FHS) defines the structure of file systems on Linux and other UNIX-like operating systems. However, Linux file systems also contain some directories that aren’t yet defined by the standard.

• With sqlalchemy how to dynamically bind to database engine on a per-request basis

  - by Peter Hansen

  I have a Pylons-based web application which connects via Sqlalchemy (v0.5) to a Postgres database. For security, rather than follow the typical pattern of simple web apps (as seen in just about all tutorials), I'm not using a generic Postgres user (e.g. "webapp") but am requiring that users enter their own Postgres userid and password, and am using that to establish the connection. That means we get the full benefit of Postgres security. Complicating things still further, there are two separate databases to connect to. Although they're currently in the same Postgres cluster, they need to be able to move to separate hosts at a later date. We're using sqlalchemy's declarative package, though I can't see that this has any bearing on the matter. Most examples of sqlalchemy show trivial approaches such as setting up the Metadata once, at application startup, with a generic database userid and password, which is used through the web application. This is usually done with Metadata.bind = create_engine(), sometimes even at module-level in the database model files. My question is, how can we defer establishing the connections until the user has logged in, and then (of course) re-use those connections, or re-establish them using the same credentials, for each subsequent request. We have this working -- we think -- but I'm not only not certain of the safety of it, I also think it looks incredibly heavy-weight for the situation. Inside the __call__ method of the BaseController we retrieve the userid and password from the web session, call sqlalchemy create_engine() once for each database, then call a routine which calls Session.bind_mapper() repeatedly, once for each table that may be referenced on each of those connections, even though any given request usually references only one or two tables. It looks something like this: # in lib/base.py on the BaseController class def __call__(self, environ, start_response): # note: web session contains {'username': XXX, 'password': YYY} url1 = 'postgres://%(username)s:%(password)s@server1/finance' % session url2 = 'postgres://%(username)s:%(password)s@server2/staff' % session finance = create_engine(url1) staff = create_engine(url2) db_configure(staff, finance) # see below ... etc # in another file Session = scoped_session(sessionmaker()) def db_configure(staff, finance): s = Session() from db.finance import Employee, Customer, Invoice for c in [ Employee, Customer, Invoice, ]: s.bind_mapper(c, finance) from db.staff import Project, Hour for c in [ Project, Hour, ]: s.bind_mapper(c, staff) s.close() # prevents leaking connections between sessions? So the create_engine() calls occur on every request... I can see that being needed, and the Connection Pool probably caches them and does things sensibly. But calling Session.bind_mapper() once for each table, on every request? Seems like there has to be a better way. Obviously, since a desire for strong security underlies all this, we don't want any chance that a connection established for a high-security user will inadvertently be used in a later request by a low-security user.

• convert.php does not run in a screen session

  - by Tobias

  I am trying to convert a big forum. At the moment I have to do this via ssh and start convert.php with "php5 -f convert.php -- $OPTIONS". But my internet connection is a bit buggy and so it is often killed. If i start the above working command in a screen session it does not work. Instead php gives me the HTML code of the "convert.php" back. head of the page: X-Powered-By: PHP/5.2.12 Set-Cookie: PHPSESSID=6bc4370b2d8d40ff8c3ab23672ff4135; path=/ Expires: Thu, 19 Nov 1981 08:52:00 GMT Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache Content-type: text/html Does it has something to do with the Sessions? But why does it work on the same ssh-connection without screen?

• Strange behaviour of code inside TransactionScope?

  - by Krishna

  We are facing a very complex issue in our production application. We have a WCF method which creates a complex Entity in the database with all its relation. public void InsertEntity(Entity entity) { using(TransactionScope scope = new TransactionScope()) { EntityDao.Create(entity); } } EntityDao.Create(entity) method is very complex and has huge pieces of logic. During the entire process of creation it creates several child entities and also have several queries to database. During the entire WCF request of entity creation usually Connection is maintained in a ThreadStatic variable and reused by the DAOs. Although some of the queries in DAO described in step 2 uses a new connection and closes it after use. Overall we have seen that the above process behaviour is erratic. Some of the queries in the inner DAO does not even return actual data from the database? The same query when run to the actaul data store gives correct result. What can be possible reason of this behaviour?

• Canon Mx772 printer recognized, drivers loaded...but all print jobs "Held"

  - by user212169

  BRAND NEW to Ubuntu but loving it so far. I have a Canon MX772 wireless printing running on my network and am able to print fine from a PC and Mac. Using the printers IP, Ubuntu was able to find it and I accepted all of the "recommended" items (it found a Canon MX770 driver). Everything seems to load fine...but the test page does not print, nor does any print commands make it to the printer. If I open the print dialogue jobs are shown as "held" and when I look at the jobs attributes, I see "Job printer state message=cannot specify model number" and then a few lines down "job state reasons=aborted by system". If I try to "resume" it immediately goes back to "held". I can successfully ping the IP of the printer. Would be very appreciative of other ideas...printing is the last check in the box before I am all set up. Thanks!

• Working with Lightweight User Interface Toolkit (LWUIT) 1.4

  - by janice.heiss(at)oracle.com

  Vikram Goyal's informative and practical article, "Working with Lightweight User Interface Toolkit (LWUIT) 1.4," shows developers how to best take advantage of LWUIT 1.4. LWUIT is a user interface library designed to bring uniformity and cross mobile interface functionality to applications developed using Java Platform, Micro Edition (Java ME). Version 1.4 offers support for XHTML, multi-line text fields, and customization to the virtual keyboard.Goyal notes in the article that, "Perhaps the most important feature of this release is the ability for LWUIT to support XHTML. Specifically, it now supports XHTML MP (Mobile Platform) 1.0, a version of XHTML designed for mobile phones. To be even more specific, it now supports CSS styling for the HTMLComponent within the LWUIT library through Wireless Application Protocol CSS (WCSS)." Read the entire article here.

• Best practice? iphone: sync data

  - by Andy Jacobs

  So i'm working on a project where there is data visualization. My ultimate goal is that i have a set of data shipped with the download of the iphone app. But i want it connected to a backend, that if the iphone has a connection with the internet. it can sync the changes from the backend. The syncing is no problem or the connection between the backend & the iphone. But what should i use as data storage on my iphone? what is the best way. my data is purely text and doesn't have to be secure. But it's main feature should be updating certain parts of data ( adding and deleting are not so important ) so what is the easiest (read: least time consuming development ) or the best way? sqlite? plist? ..?

The code works fine without rst.Close, I'm wondering if there are any dangers to not closing the object.

• OperationalError: foreign key mismatch

  - by Niek de Klein

  I have two tables that I'm filling, 'msrun' and 'feature'. 'feature' has a foreign key pointing to the 'msrun_name' column of the 'msrun' table. Inserting in the tables works fine. But when I try to delete from the 'feature' table I get the following error: pysqlite2.dbapi2.OperationalError: foreign key mismatch From the rules of foreign keys in the manual of SQLite: - The parent table does not exist, or - The parent key columns named in the foreign key constraint do not exist, or - The parent key columns named in the foreign key constraint are not the primary key of the parent table and are not subject to a unique constraint using collating sequence specified in the CREATE TABLE, or - The child table references the primary key of the parent without specifying the primary key columns and the number of primary key columns in the parent do not match the number of child key columns. I can see nothing that I'm violating. My create tables look like this: DROP TABLE IF EXISTS `msrun`; -- ----------------------------------------------------- -- Table `msrun` -- ----------------------------------------------------- CREATE TABLE IF NOT EXISTS `msrun` ( `msrun_name` VARCHAR(40) PRIMARY KEY NOT NULL , `description` VARCHAR(500) NOT NULL ); DROP TABLE IF EXISTS `feature`; -- ----------------------------------------------------- -- Table `feature` -- ----------------------------------------------------- CREATE TABLE IF NOT EXISTS `feature` ( `feature_id` VARCHAR(40) PRIMARY KEY NOT NULL , `intensity` DOUBLE NOT NULL , `overallquality` DOUBLE NOT NULL , `charge` INT NOT NULL , `content` VARCHAR(45) NOT NULL , `msrun_msrun_name` VARCHAR(40) NOT NULL , CONSTRAINT `fk_feature_msrun1` FOREIGN KEY (`msrun_msrun_name` ) REFERENCES `msrun` (`msrun_name` ) ON DELETE NO ACTION ON UPDATE NO ACTION); CREATE UNIQUE INDEX `id_UNIQUE` ON `feature` (`feature_id` ASC); CREATE INDEX `fk_feature_msrun1` ON `feature` (`msrun_msrun_name` ASC); As far as I can see the parent table exists, the foreign key is pointing to the right parent key, the parent key is a primary key and the foreign key specifies the primary key column. The script that produces the error: from pysqlite2 import dbapi2 as sqlite import parseFeatureXML connection = sqlite.connect('example.db') cursor = connection.cursor() cursor.execute("PRAGMA foreign_keys=ON") inputValues = ('example', 'description') cursor.execute("INSERT INTO `msrun` VALUES(?, ?)", inputValues) featureXML = parseFeatureXML.Reader('../example_scripts/example_files/input/featureXML_example.featureXML') for feature in featureXML.getSimpleFeatureInfo(): inputValues = (featureXML['id'], featureXML['intensity'], featureXML['overallquality'], featureXML['charge'], featureXML['content'], 'example') # insert the values into msrun using ? for sql injection safety cursor.execute("INSERT INTO `feature` VALUES(?,?,?,?,?,?)", inputValues) connection.commit() for feature in featureXML.getSimpleFeatureInfo(): cursor.execute("DELETE FROM `feature` WHERE feature_id = ?", (str(featureXML['id']),))

• Symfony: embedRelation() controlling options for nesting multiple levels of relations

  - by wulftone

  Hey all, I'm trying to set some conditional statements for nested embedRelation() instances, and can't find a way to get any kind of option through to the second embedRelation. I've got a "Measure-Page-Question" table relationship, and I'd like to be able to choose whether or not to display the Question table. For example, say I have two "success" pages, page1Success.php and page2Success.php. On page1, I'd like to display "Measure-Page-Question", and on page2, I'd like to display "Measure-Page", but I need a way to pass an "option" to the PageForm.class.php file to make that kind of decision. My actions.class.php file has something like this: // actions.class.php $this-form = new measureForm($measure, array('option'=$option)); to pass an option to the "Page", but passing that option through "Page" into "Question" doesn't work. My measureForm.class.php file has an embedRelation in it that is dependent on the "option": // measureForm.class.php if ($this-getOption('option') == "page_1") { $this-embedRelation('Page'); } and this is what i'd like to do in my pageForm.class.php file: // pageForm.class.php if ($this-getOption('option') == "page_1") { // Or != "page_2", or whatever $this-embedRelation('Question'); } I can't seem to find a way to do this. Any ideas? Is there a preferred Symfony way of doing this type of operation, perhaps without embedRelation?

• CComPtr CoCreateInstance returns 0x80070582 (Class already exists.)

  - by Trevor Balcom

  I have a StartComObjects function called when the user presses the Login button and a StopComObjects function called when the user presses the Cancel button. The StartComObjects function uses CComPtr.CoCreateInstance to create the COM object and sets up some connection points using AfxConnectionAdvise. When the user presses the Cancel button the connection points are disconnected using AfxConnectionUnadvise and the COM object is stopped before calling Release on the CComPtr. When I press the login button a second time the CComPtr.CoCreateInstance returns 0x80070582 (Class already exists). This prevents the COM object from being created on the second call to StartComObjects. I am not sure why this isn't working. Shouldn't CComPtr::Release free the COM object and allow me to create a new one after the old one was stopped? Is there any way to get around this?

• Tunnel over HTTPS

  - by ephemient

  At my workplace, the traffic blocker/firewall has been getting progressively worse. I can't connect to my home machine on port 22, and lack of ssh access makes me sad. I was previously able to use SSH by moving it to port 5050, but I think some recent filters now treat this traffic as IM and redirect it through another proxy, maybe. That's my best guess; in any case, my ssh connections now terminate before I get to log in. These days I've been using Ajaxterm over HTTPS, as port 443 is still unmolested, but this is far from ideal. (Sucky terminal emulation, lack of port forwarding, my browser leaks memory at an amazing rate...) I tried setting up mod_proxy_connect on top of mod_ssl, with the idea that I could send a CONNECT localhost:22 HTTP/1.1 request through HTTPS, and then I'd be all set. Sadly, this seems to not work; the HTTPS connection works, up until I finish sending my request; then SSL craps out. It appears as though mod_proxy_connect takes over the whole connection instead of continuing to pipe through mod_ssl, confusing the heck out of the HTTPS client. Is there a way to get this to work? I don't want to do this over plain HTTP, for several reasons: Leaving a big fat open proxy like that just stinks A big fat open proxy is not good over HTTPS either, but with authentication required it feels fine to me HTTP goes through a proxy -- I'm not too concerned about my traffic being sniffed, as it's ssh that'll be going "plaintext" through the tunnel -- but it's a lot more likely to be mangled than HTTPS, which fundamentally cannot be proxied Requirements: Must work over port 443, without disturbing other HTTPS traffic (i.e. I can't just put the ssh server on port 443, because I would no longer be able to serve pages over HTTPS) I have or can write a simple port forwarder client that runs under Windows (or Cygwin) Edit DAG: Tunnelling SSH over HTTP(S) has been pointed out to me, but it doesn't help: at the end of the article, they mention Bug 29744 - CONNECT does not work over existing SSL connection preventing tunnelling over HTTPS, exactly the problem I was running into. At this point, I am probably looking at some CGI script, but I don't want to list that as a requirement if there's better solutions available.

• Using my cell phone as remote control for PC via Bluetooth/Java

  - by Jan Kuboschek

  I've got a PC and a Samsung Eternity (that's a cell phone). I'd like to use my Eternity as remote control for my PC. Here's how I think I have to go about it: Write a desktop app (server) that accepts a connection from my cell. Write an app (client) for my cell through which I can establish a connection to the server and send commands to it. The server then executes the commands (e.g. adjust volume, pause/resume movie) Thoughts on that? Spot on or way off? Regarding the Eternity: What's a good way to get started with that? I'm guessing that I'll have to get the SDK. Does anyone have a good place to start/tutorial for that? Regarding the server: Does Java come with Bluetooth connectivity straight out of the box or do I need to fetch a library for that from somewhere? If so, from where? All help is much appreciated :)

• Microsoft releases Bing iPhone app

  As its officials have been hinting and promising for a while now, Microsoft announced it has developed a version of its Bing search app for the iPhone. The new Bing app is available on the iPhone app store as of tonight (December 15). Microsoft already offers Bing on a number of mobile phones, and has a five-year deal with Verizon to provide Bing on a number of phones available to Verizon Wireless customers. A mobile version of Bing already is available for Windows Mobile, Blackberry, BREW and Sidekick devices on Verizon. In other Bing news, Microsoft has finally hit the 10 percent market share mark with Bing, according to the November U.S. search share data from comScore. Bing’s growth is continuing to come at the expense of Yahoo, not Google. Update: To those wondering why Microsoft would deliver a version of Continue... span.fullpost {display:none;}
