  • How to programmatically call a Maven-task

    - by pmf
    I'm using Maven in the context of another build-tool (leiningen for Clojure, but this should not matter), and I would like to know how I would call a plugin like dependency:build-classpath programmatically (i.e. via the Maven-API, not via the mvn-command).

  • cookie name is truncated in Servlet 3.0 HttpServletRequest (Glassfish V3)

    - by idplmal
    I'm porting our Web authentication/authorization middleware for use in containers implementing the new servlet 3.0 API (Glassfish V3 in this case). The middleware pulls cookies from the HttpServletRequest filtering on cookies with names of the form "DACS:FEDERATION::JURISDICTION:username". This works fine in the version 2.5 servlet API but is broken in 3.0. The cookie names in 3.0 are being truncated at the first ":" in the name. I understand that the servlet 3.0 implementation defaults to RFC 2109 cookies which are more restrictive about cookie names than the old Netscape spec (":" is among the characters not allowed in RFC 2109 cookie names). Digging into the servlet 3.0 source code, it appears that the use of RFC2109 names can be disabled by setting a System property "org.glassfish.web.rfc2109.cookie_names_enforced" to false. I've tried this to no avail. But besides that, the code that uses checks cookie names is in the constructor for Cookie, and it would appear that the truncation is occurring elsewhere. So - finally - the question. Have others bumped into such issues in the servlet 3.0 API and have you found a work around?

  • Is there a way to see which Project Wizard was used to create a given Eclipse Project?

    - by Bears will eat you
    Every time I start working on a new J2EE web application, I need to create the various Eclipse projects that I'll fill up. This includes the top-level project that generates the EAR, a WAR project, etc. I usually only have to do this every couple of months, so I never remember the exact steps - specifically, which Eclipse Project Wizards to use for each project in the webapp. I have enough old J2EE projects laying around that they could serve as good reference if only I could actually see which Wizard created them. Is there a way to recover this information?

  • Choosing the right template engine

    - by asrijaal
    Hi there, since today - I always used simple JSP Tags and JSTL which works but now I'm looking for a little bit more features and maybe more usability. With googling I've found Freemaker, Velocity and Tiles which seem to be very famous. Does someone of you has some further experiences with some of these and can give me a short brief about it. Or are there other frameworks which are worth to look into?

  • Unexpected generics behaviour

    - by pronicles
    I found strange generics behaviour. In two words - thing I realy want is to use ComplexObject1 in most general way, and the thing I realy missed is why defined generic type(... extends BuisnessObject) is lost. The discuss thread is also awailable in my blog http://pronicles.blogspot.com/2010/03/unexpected-generics-behaviour.html. public class Test { public interface EntityObject {} public interface SomeInterface {} public class BasicEntity implements EntityObject {} public interface BuisnessObject<E extends EntityObject> { E getEntity(); } public interface ComplexObject1<V extends SomeInterface> extends BusinessObject<BasicEntity> {} public interface ComplexObject2 extends BuisnessObject<BasicEntity> {} public void test(){ ComplexObject1 complexObject1 = null; ComplexObject2 complexObject2 = null; EntityObject entityObject1 = complexObject1.getEntity(); //BasicEntity entityObject1 = complexObject1.getEntity(); wtf incompatible types!!!! BasicEntity basicEntity = complexObject2.getEntity(); } }

  • Automated UAT/functional tests on Swing applications without source code

    - by jas
    Our team is now working on a big Swing application. Our job basically focuses on writing extensions to the existing framework. A typical job would be adding a new panel/ or adding a new tab with some extra functionalities that suit our need. It seems FEST can help a lot in terms of unit-test our code. I am going to try it out this week. But the question here is if there is a way to do automated functional testing on the whole application. In another word, we do not only need to test our code but also the framework. After all, UAT is the most important part. I am currently considering decompiling the jar files we got into source code then we can identify the components and then use FEST. So, before I get started to give this approach a shot, I think I just ask for ideas and inspirations here. There must be people who have done similar things before. Would be nice if I could learn from the veterans who fought against this before . Thanks,

  • Android app works on emulator but not on phone ("Can't dispatch DDM chunk XXXX: no handler defined")

    - by JR_vv2
    Hey all, I made a very simple application to start playing around with Android development. It works fine on the emulator, but it gives me the following error when I try to install it on my HTC Hero (v1.5): Sorry!

  • Axis webservice calls fail sometimes, access.log shows content!

    - by epischel
    Hi, our app is a webservice client (axis 1) to a third party webservice (also axis 1). We use it for some years now. Since a few weeks, we (as a client) get sometimes HTTP status 400 (bad request) or read timeouts when calling the webservice. Strangely, the access.log of the service shows part of the request or the response instead of the URL. It looks like this (looks like the end of the request string) x.x.x.x -> y.y.y.y:8080 - - [timestamp] "POST /webservice HTTP/1.0" 200 16127 0 x.x.x.x -> y.y.y.y:8080 - - [timestamp] "POST /webservice HTTP/1.0" 200 22511 1 x.x.x.x -> y.y.y.y:8080 - - [timestamp] "il=\"true\"/><nsl:text xsi:type=\"xsd:string\" xsi:nil=\"true\"/></SOAPSomeOperation></soapenv:Body></soapenv:Envelope> Axis/1.4" 400 299 0 or (some string out of the what looks like the request) x.x.x.x -> y.y.y.y:8080 - - [timestamp] ":string\">some text</sometag><othertag>moretext" 400 299 0 or in some other cases it looks like two requests thrown together (... means xml string left out): x.x.x.x -> y.y.y.y:8080 - - [timestamp] "...</someop></soapenv:Body></soapenv:Envelope>:xsd=\"http://www.w3.org/2001/XMLSchema\"...</soapenv:Body></soapenv:Envelope>" 400 299 0 Application log does not give any hints. Frequency of such call is 1% of all calls to that service. The only discriminator I know of so far is that it happens since operations informed us that the service url changed because of "server migration". Has anyone experienced such phenomenon yet? Has somebody got an idea whats wrong and how to fix? Thanks,

  • Best practice for storage and retrieval of error messages.

    - by ferrari fan
    What is a best practice for storing user messages in a configuration file and then retrieving them for certain events throughout an application? I was thinking of having 1 single configuration file with entries such as REQUIRED_FIELD = {0} is a required field INVALID_FORMAT = The format for {0} is {1} etc. and then calling them from a class that would be something like this public class UIMessages { public static final String REQUIRED_FIELD = "REQUIRED_FIELD"; public static final String INVALID_FORMAT = "INVALID_FORMAT"; static { // load configuration file into a "Properties" object } public static String getMessage(String messageKey) { // return properties.getProperty(messageKey); } } Is this the right way to approach this problem or is there some de-facto standard already in place?

  • Regex take too long to match the result

    Hi all I have this regex pattern <(\d+)>(\d+\.\d+|\d{4}\-\d+\-\d+\s+\d{2}:\d{2}:\d{2})(?:\..*?)*\s+(ALER|NOTI) and this is my input (will not matched at all) <150>2010-12-29 18:11:30.883 -0700 192.168.2.145 80 192.168.2.87 2795 "-" "-" GET HTTP 192.168.2.145 HTTP/1.1 200 36200 0 1038 544 192.168.2.221 80 540 SERVER DEFAULT PASSIVE VALID /joomla/ "-" http://192.168.2.145/joomla/index.php?option=com_content&view=a be4d44e8f3986183a87991398c1c212e=1; be4d44e8f3986183a87991398c1c212e=1 This will return not matched result but it takes too long to output the result. Since i have a thousand of logs/inputs in a second, it should finish very fast for every single log/input. Sometime it reaches CPU 100%. Can anyone help me to solve this regex problem? Thanks

  • Spring transactions not committing

    I am struggling to get my spring managed transactions to commit, could someone please spot what I have done wrong. All my tables are mysql InnonDB tables.

  • Check if there are any repeated elements in a array recursively

    - by devoured elysium
    I have to find recursively if there is any repeated element in an integer array v. The method must have the following signature: boolean hasRepeatedElements(int[] v) I can't see any way of doing that recursively without having to define another method or at least another overload to this method (one that takes for example the element to go after or something). At first I thought about checking for the current v if there is some element equal to the first element, then creating a new array with L-1 elements etc but that seems rather inefficient. Is it the only way? Am I missing here something?

  • Multi Process Configuration

    - by user200937
    Hi, I have a product built out of multiple processes. Each process uses internally commons configuration. Does anyone have an idea how to manage the config? I.e. we do not want to duplicate variables so each process will be able to read them. Additionally, DB solution is no good, as we do not want to be dependent on DB for something like configuration. Thanks Yair

  • Using injected EntityManager in class hierarchies

    - by Emre Sahin
    The following code works: @Stateless @LocalBean public class MyClass { @PersistenceContext(name = "MyPU") EntityManager em; public void myBusinessMethod(MyEntity e) { em.persist(e); } } But the following hierarchy gives a TransactionRequiredException in Glassfish 3.0 (and standard JPA annotations with EclipseLink.) at the line of persist. @Stateless @LocalBean public class MyClass extends MyBaseClass { public void myBusinessMethod(MyEntity e) { super.update(e); } } public abstract class MyBaseClass { @PersistenceContext(name = "MyPU") EntityManager em; public void update(Object e) { em.persist(e); } } For my EJB's I collected common code in an abstract class for cleaner code. (update also saves who did the operation and when, all my entities implement an interface.) This problem is not fatal, I can simply copy update and sister methods to subclasses but I would like to keep all of them together in a single place. I didn't try but this may be because my base class is abstract, but I would like to learn a proper method for such a (IMHO common) use case.

  • How to store some of the entity's values in another table using hibernate?

    - by nimcap
    Hi guys, is there a simple way to persist some of the fields in another class and table using hibernate. For example, I have a Person class with name, surname, email, address1, address2, city, country fields. I want my classes to be: public class Person { private String name; private String surname; private String email; private Address address; // .. } public class Address { private Person person; // to whom this belongs private String address1; private String address2; private String city; private Address country; // .. } and I want to store Address in another table. What is the best way to achieve this? Edit: I am using annotations. It does not have to be the way I described, I am looking for best practices. PS. If there is a way to make Address immutable (to use as a value object) that is even better, or maybe not because I thought everything from wrong perspective :)

  • pluto or jetspeed on google app engine?

    - by Patrick Cornelissen
    I am trying to build something "portlet server"-ish on the google app engine. (as open source) I'd like to use the JSR168/286 standards, but I think that the restrictions of the app engine will make it somewhere between tricky and impossible. Has anyone tried to run jetspeed or an application that uses pluto internally on the google app engine? Based on my current knowledge of portlets and the google app engine I'm anticipating these problems: A war file with portlets is from the deployment standpoint more or less a complete webapp (yes, I know that it doesn't really work without a portal server). The war file may contain it's own web.xml etc. This makes deployment on the app engine rather difficult, because the apps are not visible to each other, so all portlet containing archives need to be included in the war file of the deployed "app engine based portal server". The "portlets" are (at least in liferay) started as permanent servlet processes, based on their portlet.xmls and web.xmls which is located in the same spot for every portlet archive that is loaded. I think this may be problematic in the app engine, because everything is in one big "web app", so it may be tricky to access the portlet.xmls from each archive. This prevents a 100% compatibility in my opinion. Is here anyone who has any experience with the combination of portlets and the app engine? Do you think it's feasible to modify jetspeed, pluto or any other portlet container to be able to run it on the app engine?
