any one good in synchronized blocks? |
| 03:51 |
|
Voyage |
any help for non-synchronized behaviour for the lines highlighted? http://pastie.org/8724549#1,9,41-42,46,49,100-101,191 |

the highlighted method / block is synchronized..... that block/method should be accessed by one method at a particular time........ |
| 04:09 |
|
Voyage |
it should be like this = first thread goes in the method, updates size, all others see that size. updated one. |
| 04:09 |
|
Voyage |
the update should have been only made by the first thread. not others |
| 04:09 |
|
Voyage |
1, why its even being run . its being run by all 11 threads. 2, it is runing without waiting for the prior thread to finish. "queue loaded, new size ------------" its creating/ adding elements |
| 04:20 |

depends. if each thread gets a fresh instance of your object, they will all run independently of each other |
| 05:03 |
|
Voyage |
sfisque, Thread thread = new Thread(new Crawler("https://www.google.com.pk/?gws_rd=cr&ei=-q8vUqqNDIny4QTLlYCwAQ#q=pakistan"/*new BasicDAO().getNonProcessedLink()*/)); |
| 05:03 |
|
Voyage |
sfisque, got one catch, synchronized methods are non-static. |
| 05:03 |
|
sfisque |
why would they be? |
| 05:04 |
|
Voyage |
but dont know about the synchrnoized(crawler.class) |
| 05:04 |
|
Voyage |
sfisque, I mean it should have been static |
| 05:04 |
|
Voyage |
right? |
| 05:04 |
|
Voyage |
in my case |
| 05:06 |
|
sfisque |
how. the method is an instance method (it's not marked as static) so how could that synchronized block be static? |
| 05:06 |
|
sfisque |
makes no sense |
| 05:06 |
|
sfisque |
the only thing syncrhonized does is give you a monitor lock before entering that block |
| 05:07 |
|
sfisque |
what you want is a single instance owned by all the threads |
| 05:07 |
|
sfisque |
i believe |
| 05:07 |
|
sfisque |
if i understand what you are trying to do |

I have a JTable within a JFrame in Netbeans. I used NetBean's Design view to create a table model with one column. Now I wanna add data to the table at runtime based on user input. How do I do it? |
| 08:57 |

kaylors: #java, aniway, did you look at the javadocs? what about setModel() ? |

with swing, things renders differently on different os.. which kinda sucks |
| 09:51 |
|
sajjadg |
fabioportieri: exactly the opposite. they render the same everywhere |
| 09:55 |
|
fabioportieri |
sajjadg: should be that way, but in reality it's not |
| 09:56 |
|
fabioportieri |
one gui you develop on windows would have glitches ported to unix system |
| 09:56 |
|
sajjadg |
fabioportieri: :-/ maybe. most things are the same. just needs little changes to be the same everywhere |
| 09:57 |
|
sajjadg |
anyway. swing is dying for a long time. |
| 09:57 |
|
sajjadg |
javafx is going to replace it soon. in a month or two |
| 09:57 |
|
sajjadg |
jdk 8 ships with javafx I think |
| 09:57 |
|
fabioportieri |
let's hope so, swing is a pita |

Swing is not just a PITA ., its not been seriously updated in 15 years |

there's a class in the jdk, sun.nio.fs.Globs, which has two package-private (no access modifier) static methods |
| 16:25 |
|
semiosis |
i want to use those classes from my package, so i added a proxy class to my project... sun.nio.fs.PublicGlobs, with one *public* static method that calls the package private static method in the original class |
| 16:25 |
|
semiosis |
here's the problem |
| 16:25 |
|
semiosis |
when i try to run in IDEA it says that my class sun.nio.fs.PublicGlobs doesn't have access to method sun.nio.fs.Globs.foo (the package private static method) |
| 16:26 |
|
semiosis |
when i try to run in maven it says that the original sun.nio.fs.Globs class can't even be found! |
| 16:26 |
|
semiosis |
can anyone tell me what's going on??? |

generally it's a bad idea to use anything in sun.* |
| 16:38 |
|
tjsnell |
oh wait |
| 16:38 |
|
tjsnell |
bad idea to use com.sun.* |
| 16:38 |
|
tjsnell |
never ever use sun.* |

|
sajjadg joined ##javaee |

tjsnell: please explain |
| 16:45 |
|
tjsnell |
sun.* are internal implementation classes never intended for end user access |
| 16:45 |
|
semiosis |
tjsnell: my backup plan is to just copy the code into my project, it is GPL+CP and i'm using this in an open source project |
| 16:46 |
|
tjsnell |
heh |
| 16:46 |
|
semiosis |
tjsnell: can you offer any alternatives? |

since I have no clue what those do, no. |

this code converts a shell glob pattern into a regex |
| 16:46 |
|
semiosis |
shell glob being, for example "**/*.gz" |
| 16:47 |
|
semiosis |
it's used internally by the java.nio.file.Files stuff (NIO.2) |
| 16:47 |
|

i found something called jakarta oro that might do this as well, but that's in the apache attic now |

but it's only a subset of the JEE stack, you can't put everything in to a war |

Do I need to add a JAXB implementation to my project if I'm deploying to a glassfish AS? |
| 19:28 |
|
sajjadg |
it seems that glassfish has a JAXB implementation by default :-/ |
| 19:28 |
|
sajjadg |
it's marshalling already but it's adding additional @ to the JSON output |
| 19:29 |
|
sajjadg |
the solution is to use @XMLElement instead of @XMLAttribute but it's not working for me! |
| 19:29 |
|
whartung |
jaxb is built in to glass fish. Jersey bundles the json support for it |
| 19:30 |
|
sajjadg |
so if I have jersey dependency in my pom.xml then I don't need any other JAXB impl. good. ASes have lots of things :P |
| 19:33 |
|
acuzio |
Not all of them good |
| 19:34 |
|
sajjadg |
jersey and resteasy are both JAX-RS JSR implementation and former is bundled with glassfish and latter bundled/developed/included in jboss/wildfly. so if for example I have a working webservice that is using jersey and then I want to change my AS to jboss/wildfly can I use jersey with jboss/wildfly or I need to change jersey to resteasy? |
| 19:35 |
|
sajjadg |
shit. netbeans started transfering maven index again |

ideally, you don't have to swap them out. That's what "coding to the standard" is supposed to by you. The reality may be different, but perfect world is that it would Just Work(tm). |

this @ is fucking aweful. in JAXB if you have xml attribute then you get @ before its name after marshalling and for property you get names without @ |

it seems I should do something in client side |

old version of jersey used to has some workaround but in the last version I can't find any solution |
