I'm not talking about using COM components out of groovy, but the other direction. Best regards Alex __________________________________________________ Do You Yahoo!? Sie sind Spam leid? Yahoo!

I tried both XmlParser and XmlSlurper, and all combinations of findAll that I could think of. I am a Groovy-Newbie (I should trademark that :-)) and searched the Groovy home, as well as all of my Groovy books. Any ideas? ----- G. Ralph Kuntz, MD Chief Software Architect meridianEMR, Inc. grkuntzmd 2008-08-21T11:55:52 http://comments.gmane.org/gmane.comp.lang.groovy.user/35305 Hello, Yesterday, in my ongoing effort to promote Groovy in my work, I held a technical presentation for my collegues. It was well recieved and people seemed interested in the lagnuage. There where a number of questions that came out of the session and I was hoping maybe the people on this mialing list would be willing to offer their two cents. Below is a section of a mail I received any responses would be greatly appreciated. ---- Based on the "dynamic" nature of the language 2 things that came to mind that I would probably be interested in if I was an IT manager (particularly in financial organisations) were testing and security. In relation to the testing I was wondering how can we ensure a sufficient level of code coverage in the testing of any application. Are there scenarios that could easily be missed because we don't simulate the conditions that cause some piece of code/method to get dynamically generated and executed thus giving rise to very unexpected behaviour in an application. I think there were similar type concerns in the early days of Inversion of Control (i.e. if the framework is calling the code do we know all the points it wil call it) that have never been an issue, so it may be the same here, but nevertheless if I was that IT Manager I'd want to know. In relation to security, I was wondering if the black hat guys are sitting out there with ways to hack into organisations and finding ways to dynamically run snippets of code in the Groovy environment. Its always an issue trying to stop people getting in to your environment in the first place, but do applicaitons based on this type of technology make it any easier for the bad guys to do damage once they are in?? ---- Thanks James Hughes | Senior Software Engineer | Kainos | M: +353 (0)877 931 634 | j.hughes-fZ2kPDQGsinQT0dZR+AlfA< at >public.gmane.org P Please consider the environment and do not print this mail unless necessary -------------------------------------------------------------------- This e-mail is intended solely for the addressee and is strictly confidential; if you are not the addressee please destroy the message and all copies.

Ralph Kuntz, MD Chief Software Architect meridianEMR, Inc. grkuntzmd 2008-08-21T11:40:41 http://comments.gmane.org/gmane.comp.lang.groovy.user/35300 I am a Groovy-Newbie and this is a theoretical question In a project I am working on, we have POJOs with setters of the following form: // Java Code public class Person { private String name; // Set the name value only if it changes, then mark the POJO dirty public void setName(String name) { if ((name == null) ? this.name != null : !name.equals(this.name)) { this.name= name; this.dirty = true; } } } Without arguing the philosophy of this approach, is it possible to use MOP in Groovy to automatically "inject" the equality checks and dirty flag setting (ala aspects)? As it stands, each of these setters needs unit testing because it contains "logic" code (as in Dierk K&ouml;nig's interview on unit testing with Sven Haiges in the Grails podcast series). If the boilerplate setter code could be injected, these methods would not each need separate units tests. ----- G.

To learn more see: www.gradle.org Here is a summary of the most interesting new features and improvements: - Gradle provides now a separate JDK 1.4. compatible distributions. - We have improved the handling and naming conventions for archive tasks. See user's guide (UG) 9.7.3. - The War plugin is now much more flexible regarding library handling. Gradle provides now a provided configuration to add libraries that should be used for compile and testing, but should not be bundled with the war. See UG 11. - After going through a lot of pain with the windows start scripts we have decided to get rid of them and replace them with exe commands generated by launch4j. Thanks to Adam Pohorecki for contributing the foundations for this. - To improve the responsiveness of Gradle the compiled build and settings files are now cached. For how to control the cache, see UG 4.6. - Every task action has now access to the graph of the tasks to be executed. See UG 2.10. - The wrapper task is now much more configurable regarding where the involved files are stored. See UG 16. - We have started to implement a listener framework around the Gradle lifecycle. You can now register for example an afterEvaluateListener with a project which gets called after a project's build script is evaluated. For an example see UG 14.2.3. - The Test task generates now JUnit HTML reports. - Gradle enables now to execute tasks via their absolute path. See UG 14.4. - You can now define default tasks. See UG 2.9. - You can define now global exclude for dependencies. See UG 12.2.6. - Due to Groovydoc problems, we were not able to provided reasonable API doc in the past. This has changed now. For a big part of our public API we provide now Javadoc. With the release of 0.4 we will be able to provide this for all our API. For our roadmap see: http://gradle.org/roadmap.html Cheers, - Hans -- Hans Dockter Gradle Project lead http://www.gradle.org --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email Hans Dockter 2008-08-21T07:37:37 http://comments.gmane.org/gmane.comp.lang.groovy.user/35286 Sorry from what I'm sure is a FAQ (I checked the FAQ and tried to search the mailing list archives first; no luck), How do I test for a variable being defined?

I have been stuck up with calling a stored procedure from groovy code. I am able to run the stored procedure but not able to retreive the output from th stored procedure. i am working on this issue for more than two days. I would be grateful if any could help me out. My code is def row = sql.execute("{call Web_User_Insert(?,?,?,?,?,?,?,?,?,?)}", [webuser.firstName,webuser.lastName, webuser.username, webuser.password,webuser.emailAddress,0,0,0,lastInsertId,failureCode]) I am able to run the code and changes are reflected. But my question is when i run this procedure i need to get back two outputs lastInsertId and failure code. please help me out. Thanks. rajnarasimhan 2008-08-20T19:14:28 http://comments.gmane.org/gmane.comp.lang.groovy.user/35267 I'm trying to understand tracing via invokeMethod, and I'm having behavior I don't understand. In the code (included at the end, ripped of unashamedly from GINA) I have a closure and a method that both call another method 'outer', which calls 'inner'. I expected them both to show tracing for both outer and inner, but only the method does. The closure traces the inner method, but not the outer. What is it that I'm completely failing to understand? I'm using Groovy 1.5.6 The larger task I'm trying to accomplish is to be able to use the excellent runtimeLogging plugin to allow me to turn on tracing on-the-fly for my Grails app. What I want is a superclass that I can use for controllers as well as some files in the /src directory to have all the code in one place. That is, I can subclass my controllers as well as other classes and get detailed tracing all at once. It seems to be working reasonably well, except for this issue. If there are other ways to make this work, I'd be happy to use them instead <G>. But this issue seems to be a pure Groovy issue that's at the heart of my problem.

The compiler choked on this code in the plugin: class GroovyMacro extends org.radeox.macro.Preserved { String name = "groovy" String description = "formatting Groovy code" String[] paramDescription = ["no params, Groovy code goes inside a pair of groovy tags"]; GroovyMacro() { '[]{}*-\\'.each { addSpecial(it as char) } } void execute(Writer writer, org.radeox.macro.parameter.MacroParameter params) { writer << "<PRE>" writer << replace(params.content) writer << "</PRE>" } } It fails to compile this class because: /Users/marc/.grails/1.0.3/projects/Copella/generated-java-source/ GroovyMacro.java:8: GroovyMacro is not abstract and does not override abstract method getName() in org.radeox.macro.BaseMacro public class GroovyMacro ^ Basically it looks like with Groovy 1.5.4, the auto-generated getName() implementation was accepted as an implementation of the radeox abstract base class's "String getName()". In Groovy 1.5.6 this seems broken. Is this a bug I need to Jira?

Thanks Great 2008-08-20T03:06:34 http://comments.gmane.org/gmane.comp.lang.groovy.user/35240 Ok, I have more information about what was causing the failure I mention below. The three independent projects had very similar refactorings on the same day, so ignore the fact that it happened to multiple projects. Basically GMaven is puking when I have an instance variable in my class that doesn't have a modifier. Here's an excerpt of one class that's causing the failure: class TestBaseSpring extends AssertionContextGroovyTestCase { protected final static Logger logger = Logger.getLogger(TestBaseSpring.class) private final static String HARNESS_BEAN_FILE = "spring-config.xml"; private final static String LOCAL_BEANS_FILE_DEFAULT = "test-spring-config.xml"; private final static String ENV_SYSTEM_PROP = "local.beans.filename"; public static ConfigObject testConfig public static ApplicationContext spring ManagedDataServiceTestClient<Media> client // this causes the failure (... etc) If I give client a modifier, e.g. public/private/protected, it all compiles fine.
