• Unix crypt() function in smalltalk/pharo

  - by jdinuncio

  Hello, I want to encode passwords for UNIX accounts using the crypt function. I'm using pharo 1.0. I tried to install the crypto package from squeakmap, but it gaves me an error and the package seem to get partially installed (categories without class). How can I get my password crypted? I'm willing to invoke external code, if it is required (and there's a package in SqueakMap that makes the trick in pharo). Thanks.

• Do Eclipse's Refactoring Tools Violate The Java Language Specification?

  - by Tom Tresansky

  In Eclipse 3.5, say I have a package structure like this: tom.package1 tom.package1.packageA tom.package1.packageB if I right click on an the tom.package1 package and go to Refactor-Rename, an option "Rename subpackages" appears as a checkbox. If I select it, and then rename tom.package1 to tom.red my package structure ends up like this: tom.red tom.red.packageA tom.red.packageB Yet I hear that Java's packages are not hierarchical. The Java Tutorials back that up (see the section on Apparent Hierarchies of Packages). It certainly seems like Eclipse is treating packages as hierarchical in this case. I was curious why access specifiers couldn't allow/restrict access to "sub-packages" in a previous question because I KNEW I had seen "sub-packages" referenced somewhere before. So are Eclipse's refactoring tools intentionally misleading impressionable young minds by furthering the "sub-package" myth? Or am I misinterpreting something here?

• Autoconf macros for Apache and conf.d install process?

  - by Stephen Burke

  I have a package that is using the autotools to build and install. Part of the package is a website that can be run on the local machine. So in the package there is a .conf file that is meant to be either copied or linked to the /etc/apache2/conf.d directory. What's the standard way that packages would do this? If possible, I'd like for the user not to have an extra step to make the website work. I'd like to have them install the package and then be able to browse to http://localhost/newpackage to get up and running. Also, is there a way that autoconf knows about the apache install or a standard way through then environment some how? If someone could point me in the right direction that would be great. Steve

• Use of (non) qualified names

  - by AProgrammer

  If I want to use the name baz defined in package foo|bar|quz, I've several choices: provide fbq as a short name for foo|bar|quz and use fbq|baz use foo|bar|quz|baz import baz from foo|bar|quz|baz and then use baz (or an alias given in the import process) import all public symbols from foo|bar|quz|baz and then use baz For the languages I know, my perception is that the best practice is to use the first two ways (I'll use one or the other depending on the specific package full name and the number of symbols I need from it). I'd use the third only in a language which doesn't provide the first and hunt for supporting tools to write the import statements. And in my opinion the fourth should be reserved to package designed with than import in mind, for instance if all exported symbols start with a prefix or contains the name of the package. My questions: what is in your opinion the best practice for your favorite languages? what would you suggest in a new language? what would you suggest in an old language adding such a feature?

• NuGet Update Error?

  - by Myles McDonnell

  Using the NuGet package manager dialog at the solution level in the normal course of updating a package reference once the process is complete there is a green tick on the item and the update button disappears. However, with certain of my packages the update process completes, as far as I can tell successfully, but no green tick and the update button remains. Press it again and the next dialog shows that no projects require an update for that package. Am I missing something here or is this a bug?

• Serving static content with Struts2: Tomcat error 404

  - by Nicolas Raoul

  With Struts2 I can't find a way to serve a static CSS :-/ Newbie question but I could not find any answer on the Internet: The CSS file is static/styles.css in my WAR file. Tomcat replies with 404 when I request http://server/myapp/static/styles.css But it works if I put styles.css at the root of the WAR and request http://server/myapp/styles.css I tried adding the following to my struts.xml in the only package but still 404: <action name="/static/*"> <result>/static/{1}</result> </action> Or as a second package: <package name="static" extends="struts-default" namespace="/static"> <action name="/static/*"> <result>/static/{1}</result> </action> </package>

Thanks Maddy

• Static nested class visibility issue with Scala / Java interop

  - by Matt R

  Suppose I have the following Java file in a library: package test; public abstract class AbstractFoo { protected static class FooHelper { public FooHelper() {} } } I would like to extend it from Scala: package test2 import test.AbstractFoo class Foo extends AbstractFoo { new AbstractFoo.FooHelper() } I get an error, "class FooHelper cannot be accessed in object test.AbstractFoo". (I'm using a Scala 2.8 nightly). The following Java compiles correctly: package test2; import test.AbstractFoo; public class Foo2 extends AbstractFoo { { new FooHelper(); } } The Scala version also compiles if it's placed in the test package. Is there another way to get it to compile?

• Android Template Application?

  - by stormin986

  I have built an application that I want to use as the foundation for a few other variants. The variants will come from assets / resource files and a unique AndroidManifest.xml. However, I want to be able to leave all the application code alone (modifying the package of all my classes, etc). I'm having a hard time figuring out how to do so. My first thought was to simply have my main application in its own package, and then specify the specific application package in the manifest. However, this gives me issues with the generated R.java class, since it is generated to be in the main application's package. Anyone have any thoughts on how to accomplish this? To have a code baseline, and the application variants happen in resources/assets and the manifest?

• do not use com.sun.xml.internal.*?

  - by sarah xia

  Hi all, Is this statement true: com.sun.xml.internal package is an internal package as the name suggestes. Users should not write code that depends on internal JDK implementation classes. Such classes are internal implementation details of the JDK and subject to change without notice One of my colleagues used one of the classes in his code, which caused javac task in Ant fail to compile our project as the compiler couldn't find the class. Answer from Sun/Oracle says that this is expected behavior of the compiler as user shouldn't use the package. Question is why the classes in the package made public in the first place? Thanks, Sarah

• iPhone OS SDK: Possible to download SDK 3.0 w/o Xcode?

  - by Cirrostratus

  I recently downloaded the iPhone SDK 4 along with Xcode and neglected to install 3.0 and 3.1. I've since deleted the install package. I of course can re-download the whole package, but for future reference, I wonder if you are able to download individual SDK versions separately and independent of Xcode, like you would with almost any open source package.

• How do I configure SSIS logging to overwrite the log file?

  - by theog

  My SSIS package has logging configured with a SSIS log provider for text files, which works fine, but each time the package is run the log appends to the end of the log file. I want it to truncate the file and only keep the log from the most recent execution of the package, but I don't see an option anywhere to do that. I've tried both file usage types (Existing file and New file) in the File Connection manager with the same results.

• zsh for loop exclusion

  - by ABach

  This is somewhat of a simple question, but for the life of me, I cannot figure out how to exclude something from a zsh for loop. For instance, let's say we have this: for $package in /home/user/settings/* do # do stuff done Let's say that in /home/user/settings/, there is a particular directory ("os") that I want to ignore. Logically, I tried the following variations: for $package in /home/user/settings/^os (works w/ "ls", but not with a foor loop) for $package in /home/user/settings/*^os for $package in /home/user/settings/^os* ...but none of those seem to work. Could someone steer my syntax in the right direction?

• RMO on Windows 7 - The Specified module could not be found

  - by AGoodDisplayName

  My machine: Windows XP (x86), VS2008, .net 3.5, sql server 2005, WinForms - App works fine. Production Machines: Windows 7 (x64), SQl Server 2005 Express - App Starts but throws exception Visual Studio Targeting x86 on setup project and RMO project. Visual Studio gives me a a couple warnings but I can still build: Unable to find dependency 'MICROSOFT.SQLSERVER.MANAGEMENT.SQLPARSER' (Signature='89845DCD8080CC91' Version='10.0.0.0') of assembly 'Microsoft.SqlServer.Smo.dll' Unable to find dependency 'MICROSOFT.SQLSERVER.MANAGEMENT.SQLPARSER' (Signature='89845DCD8080CC91' Version='10.0.0.0') of assembly 'Microsoft.SqlServer.Management.SmoMetadataProvider.dll' This is a simple RMO (Replication Management Objects) app that initiates a pull subscription in SQL Server 2005 and displays status.

• Remote application monitoring through Visual GC

  - by Poole

  I am trying to monitor an application available on remote machine using VisualVM & Visual GC. I have enabled the jmxremote on the remote side as follows: -Dcom.sun.management.jmxremote, -Dcom.sun.management.jmxremote.port=8888, -Dcom.sun.management.jmxremote.ssl=false, -Dcom.sun.management.jmxremote.authenticate=false While monitoring through VisualVM, everything runs fine but VisualGC doesn't displays any stats (getting Not Supported for this JVM error). While tried to monitor one local application, VisualGC runs fine... Got success with the remote app once started jstad on the remote jvm. Is this a known issue with VisualGC...?

• Guice ThrowingProvider problem

  - by KARASZI István

  According to the ThrowingProvider documentation of Guice I have the following interface: public interface IConfigurableProvider<T> extends ThrowingProvider<T, ConfigException> {} I have multiple classes that implements this interface, let assume I have the following: public class SomethingProvider extends ConfiguredProvider implements IConfigurableProvider<Something> {} Of course this class implements the necessary method: public Something get() throws ConfigException { /* ... */ } In my module, I have the following code in MyModule.java ThrowingProviderBinder.create(binder()) .bind(IConfigurableProvider.class, Something.class) .to(SomethingProvider.class); But when I start my application the following error produced: 6) No implementation for com.package.Something was bound. while locating com.package.Something for parameter 5 at com.package.OtherClass.<init>(OtherClass.java:78) at com.package.MyModule.configure(MyModule.java:106) I don't really know where should I start looking for the bug.

• Multiple Exception Handling in one if statement [closed]

  - by JA3N

  I am having trouble with throwing and catching exceptions. Here is the code for assignSeat(), assignSeat is called in a try block in another class. void assignSeat(String passengerName, int x, int y) throws SeatOccupiedException, InvalidPassengerNameException { Seat tSeat = airplane.getSeat(x,y); if (tSeat!=null) { if (passengerName.isEmpty() || !passengerName.matches("[a-zA-Z]+")) { throw new InvalidPassengerNameException(); } //excluded else if else if (foundPassenger(passengerName)) { airplane.seatList.get(airplane.seatNumber(passengerName)).unOccupy(); tSeat.occupy(); for (int i = 0; i<passengers.size();i++) if (passengers.get(i).getName().equals(passengerName)) passengers.get(i).changeSeat(tSeat.getSeatName()); } else if (!tSeat.occupied) { tSeat.occupy(); addPassenger(passengerName, tSeat.getSeatName()); } else if (tSeat.occupied) { throw new SeatOccupiedException(); } } and here is the code that calls assignSeat() and is in another class (I won't copy the whole class to make it look clearer) if (afComp.currentAF != null) { try { afComp.currentAF.assignSeat(nameField.getText(), x, y); //<-Problem here, "Unhandled exception type SeatOccupiedException" } catch (SeatOccupiedException exception) //<-Problem here, "Unreachable catch block, This exception is never thrown from the try statement body" { } catch(InvalidPassengerNameException exception) //<-No problems. { } } Whats wrong with the try block? why won't it throw the SeatOccupiedException? Exception classes: SeatOccupied: package a2; public class SeatOccupiedException extends Exception { public SeatOccupiedException(){} } InvalidPassengerName: package a2; public class InvalidPassengerNameException extends Exception { public InvalidPassengerNameException() {} } Every class I have is in package a2 imports for class that calls assignSeat package a2; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.MouseListener; import java.awt.event.MouseMotionListener; import java.awt.event.MouseEvent; import java.awt.BorderLayout; import javax.swing.*; import javax.swing.event.*; imports for class that has assignSeat package a2; import java.util.ArrayList;

• Cannot Generate ParameterSetMetadata While Programmatically Creating A Parameter Block

  - by Steven Murawski

  I'm trying to programmatically create a parameter block for a function ( along the lines of this blog post ). I'm starting with a CommandMetadata object (from an existing function). I can create the ParameterMetadata object and set things like the ParameterType, the name, as well as some attributes. The problem I'm running into is that when I use the GetParamBlock method of the ProxyCommand class, none of my attributes that I set in the Attributes collection of the ParameterMetadata are generated. The problem this causes is that when the GetParamBlock is called, the new parameter is not annotated with the appropriate Parameter attribute. Example: function test { [CmdletBinding()] param ( [Parameter()] $InitialParameter) Write-Host "I don't matter." } $MetaData = New-Object System.Management.Automation.CommandMetaData (get-command test) $NewParameter = New-Object System.Management.Automation.ParameterMetadata 'NewParameter' $NewParameter.ParameterType = [string[]] $Attribute = New-Object System.Management.Automation.ParameterAttribute $Attribute.Position = 1 $Attribute.Mandatory = $true $Attribute.ValueFromPipeline = $true $NewParameter.Attributes.Add($Attribute) $MetaData.Parameters.Add('NewParameter', $NewParameter) [System.Management.Automation.ProxyCommand]::GetParamBlock($MetaData)

• Python Class inherit from all submodules

  - by Dhruv Govil

  I'm currently writing a wrapper in python for a lot of custom company tools. I'm basically going to break each tool into its own py file with a class containing the call to the tool as a method. These will all be contained in a package. Then there'll be a master class that will import all from the package, then inherit from each and every class, so as to appear as one cohesive class. masterClass.py pyPackage - __ init__.py - module1.py --class Module1 ---method tool1 - module2.py --class Module2 ---method tool2 etc Right now, I'm autogenerating the master class file to inherit from the packages modules, but I was wondering if there was a more elegant way to do it? ie from package import * class MasterClass(package.all): pass
