• 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?

• Problem making ant compile my classes present in different Eclipse projects into single destination

  - by KCore

  I have close to about 20 projects in my Eclipse workspace. They are interdependent. Now I want to build all of them in a single war file. The thing is eclipse does it nicely... if I create a Dynamic Web Project and link sources of all the 20 projects. But I want to automate the entire process and want to be able to run a script (ant maybe..) and deploy a war in my app server. My approach: I started with a simple approach. I tried to sequentially build each project (javac task) with destination directory as web-inf of my war. But it is giving me weird errors like : package " ** " not found,when it shows the same all the required classes in classpath (I used verbose) Do you think, a continous integration engine will be better for my case (20 projects..) I saw Team City, but didnt get it the first time...

• Importing hibernate configuration file into Spring applicationContext

  - by Himanshu Yadav

  I am trying to integrate Hibernate 3 with Spring 3.1.0. The problem is that application is not able to find mapping file which declared in hibernate.cfg.xml file. Initially hibernate configuration has datasource configuration, hibernate properties and mapping hbm.xml files. Master hibernate.cfg.xml file exist in src folder. this is how Master file looks: <hibernate-configuration> <session-factory> <!-- Mappings --> <mapping resource="com/test/class1.hbm.xml"/> <mapping resource="/class2.hbm.xml"/> <mapping resource="com/test/class3.hbm.xml"/> <mapping resource="com/test/class4.hbm.xml"/> <mapping resource="com/test/class5.hbm.xml"/> Spring config is: <bean id="sessionFactoryEditSolution" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="data1"/> <property name="mappingResources"> <list> <value>/master.hibernate.cfg.xml</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop> <prop key="hibernate.cache.use_second_level_cache">true</prop> </props> </property> </bean>

• Junit Parameterized tests together with Powermock - how!?

  - by Subtwo

  Hi! I've been trying to figure out how to run parameterized tests in Junit4 together with PowerMock. The problem is that to use PowerMock you need to decorate your test class with @RunWith(PowerMock.class) and to use parameterized tests you have to decorate with @RunWith(Parameterized.class) From what I can see they seem mutually excluded!? Is this true? Is there any way around this? I've tried to create a parameterized class within a class running with PowerMock; something like this: @RunWith(PowerMock.class) class MyTestClass { @RunWith(Parameterized.class) class ParamTestClass { // Yadayada } } But unfortunately this doesn't do much good... The ParamTestClass still doesn't run with PowerMock support (not that surprisingly maybe)... And I've kind of run out of ideas so any help is greatly appreciated!

• Iterables.find and Iterators.find - instead of throwing exception, get null

  - by mjlee

  I'm using google-collections and trying to find the first element that satisfies Predicate if not, return me 'null'. Unfortunately, Iterables.find and Iterators.find throws NoSuchElementException when no element is found. Now, I am forced to do Object found = null; if ( Iterators.any( newIterator(...) , my_predicate ) { found = Iterators.find( newIterator(...), my_predicate ) } I can surround by 'try/catch' and do the same thing but for my use-cases, I am going to encounter many cases where no-element is found. Is there a simpler way of doing this?

• Getting hibernate to log clob parameters

  - by SCdF

  (see here for the problem I'm trying to solve) How do you get hibernate to log clob values it's going to insert. It is logging other value types, such as Integer etc. I have the following in my log4j config: log4j.logger.net.sf.hibernate.SQL=DEBUG log4j.logger.org.hibernate.SQL=DEBUG log4j.logger.net.sf.hibernate.type=DEBUG log4j.logger.org.hibernate.type=DEBUG Which produces output such as: (org.hibernate.SQL) insert into NoteSubstitutions (note, listIndex, substitution) values (?, ?, ?) (org.hibernate.type.LongType) binding '170650' to parameter: 1 (org.hibernate.type.IntegerType) binding '0' to parameter: 2 (org.hibernate.SQL) insert into NoteSubstitutions (note, listIndex, substitution) values (?, ?, ?) (org.hibernate.type.LongType) binding '170650' to parameter: 1 (org.hibernate.type.IntegerType) binding '1' to parameter: 2 However you'll note that it never displays parameter: 3 which is our clob. What I would really want is something like: (org.hibernate.SQL) insert into NoteSubstitutions (note, listIndex, substitution) values (?, ?, ?) (org.hibernate.type.LongType) binding '170650' to parameter: 1 (org.hibernate.type.IntegerType) binding '0' to parameter: 2 (org.hibernate.type.ClobType) binding 'something' to parameter: 3 (org.hibernate.SQL) insert into NoteSubstitutions (note, listIndex, substitution) values (?, ?, ?) (org.hibernate.type.LongType) binding '170650' to parameter: 1 (org.hibernate.type.IntegerType) binding '1' to parameter: 2 (org.hibernate.type.ClobType) binding 'something else' to parameter: 3 How do I get it to show this in the log?

• How to parameterize @Scheduled(fixedDelay) with Spring 3.0 expression language?

  - by ngeek

  When using the Spring 3.0 capability to annotate the a scheduled task, I would like to set the fixedDelay as parameter from my configuration file, instead of hard-wiring it into my task class, like currently... @Scheduled(fixedDelay=5000) public void readLog() { ... } Unfortunately it seems that with the means of the Spring Expression Language (EL) @Value returns a String object which in turn is not able to be auto-boxed to a long value as required by the fixedDelay parameter. Thanks in advance for your help on this.

• Object suddenly missing from HttpServletRequest

  - by Jeune

  I print a list directly in the servlet using the print writer and the list prints. When I try to put in the jsp however the list doesn't print whether I use JSTL or scriptlets. I tried to test in JSTL and scriptlet if the object is null and turns out that it is! Why does this happen and how can I fix this? Servlet code that works for (Artist artist:artists){ resp.getWriter().println(artist.getName()); } Servlet code that puts object in the request public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException { ApplicationContext ctx = new ClassPathXmlApplicationContext("com/helloworld/beans/helloworld-context.xml"); ArtistDao artistDao = (ArtistDao) ctx.getBean("artistDao"); List<Artist> artists = null; try { artists = artistDao.getAll(); } catch (SQLException e) { e.printStackTrace(); } req.setAttribute("artists", artists); try { req.getRequestDispatcher("index.jsp").forward(req, resp); } catch (ServletException e) { e.printStackTrace(); } scriptlet code that suddenly finds the object null <% List<Artist> artists = (List<Artist>) request.getAttribute("artists"); if (artists == null) { out.println("artists null"); } else { for (Artist artist: artists){ out.println(artist.getName()); } } %> Even the jstl code seems to agree <c:if test="${artists eq null}"> Artists are null </c:if> <c:forEach var="artist" items="${artists}"> ${artist.name} </c:forEach> For my app I am using weblogic, spring 2.5.6 and ibatis.

• Custom Classes Passed from Service to a UI threads via AIDL

  - by Honza Pokorny

  I have a service that regularly queries a web server for new messages. The service stores the new messages in an arrayList. These messages are implemented using a custom class, storing all kinds of metadata (strings and longs). An activity then connects to this service to retrieve those messages and display them to the user. I have an .aidl file that describes the interface that the service exposes. package com.example.package; interface MyInterface { List<Message> getMessages(); } The Message class extends the Parcelable class which should allow for the IPC transfer. The problem is this: Eclipse gives me an error saying that the type of List<Message> is unknown. Any imports are marked as invalid. Ideas? Thanks

• How do I lock the layout of my android program to one orientation

  - by Mike V

  I'm trying to write a program that needs smooth orientation sensor samples as the phone is rotated all around. Every time the orientation of the phone is changed, it interrupts the data and freezes the program while the layout changes. How can I lock it in one orientation (landscape or portrait, it doesn't matter)? I assume it has something to do with android:layout in the xml file, but I can't find anything online.

• JCo | How to iterate column wise

  - by cedar715

  The data from SAP is returned as a JCo.Table. However, we don't want to display ALL the columns in the VIEW. So, what we have done is, we have created a file called display.xml which has the JCO.Table columns to be displayed. The display.xml is converted to a List and each field is verified if it is present in the display list(see the code below) which is redundant from second row onwards. final Table outputTable = jcoFunction.getTableParameterList(). getTable("OUTPUT_TABLE"); final int numRows = outputTable.getNumRows(); for (int i = 0; i < numRows; i++) { final FieldIterator fields = outputTable.fields(); while (fields.hasNextFields()) { final JCO.Field recordField = fields.nextField(); final String sapFieldName = recordField.getName(); final DisplayFieldDto key = new DisplayFieldDto(sapFieldName); if (displayFields.contains(key)) { System.out.println("recordField.getName() = " + recordField.getName()); final String sapFieldName = (String)recordField.getValue(); } else { // ignore the field. } } } What is the better way to filter the fields in JCo? Can I iterate column wise? Thank you :)

• Hibernate query for multiple items in a collection

  - by aarestad

  I have a data model that looks something like this: public class Item { private List<ItemAttribute> attributes; // other stuff } public class ItemAttribute { private String name; private String value; } (this obviously simplifies away a lot of the extraneous stuff) What I want to do is create a query to ask for all Items with one OR MORE particular attributes, ideally joined with arbitrary ANDs and ORs. Right now I'm keeping it simple and just trying to implement the AND case. In pseudo-SQL (or pseudo-HQL if you would), it would be something like: select all items where attributes contains(ItemAttribute(name="foo1", value="bar1")) AND attributes contains(ItemAttribute(name="foo2", value="bar2")) The examples in the Hibernate docs didn't seem to address this particular use case, but it seems like a fairly common one. The disjunction case would also be useful, especially so I could specify a list of possible values, i.e. where attributes contains(ItemAttribute(name="foo", value="bar1")) OR attributes contains(ItemAttribute(name="foo", value="bar2")) -- etc. Here's an example that works OK for a single attribute: return getSession().createCriteria(Item.class) .createAlias("itemAttributes", "ia") .add(Restrictions.conjunction() .add(Restrictions.eq("ia.name", "foo")) .add(Restrictions.eq("ia.attributeValue", "bar"))) .list(); Learning how to do this would go a long ways towards expanding my understanding of Hibernate's potential. :)

• AdMob Android integration - what permissions to ask for?

  - by AngryHacker

  In the various videos on the AdMob integration, I've seen that only permission to access the internet is asked for: <uses-permission android:name="android.permission.INTERNET" /> Not that I am an expert in advertising, but wouldn't AdMob need the user's geographic location as well, so that they can serve location specific ads? Or avoid serving certain ads based on a location, like maybe not offering me a Big Mac if I am in India or not adverting a ham sandwich if I am in an Arab country? If AdMob needs those permissions, how do I ask for them?

Tried to Google for the answer, but couldn't find any answer regarding this - everyone just said "Google collection should work off the box with GWT".

• Grails Deployment - Fastest way to get deployed?

  - by gav

  Hi All, If anyone has or is running a Grails application on their server I would appreciate some details on where to go after creating the WAR. Background I chose grails because with Google App Engine and the App Engine Plugin deployment should have been trivial. This issue is that there is a bug which makes any application pretty much unusable, I wish this had been more prominent so I didn't have to get to the point of seeing the error myself before I was aware of it. The next option was EC2 and the Cloud Tools plugin, it seems Cloud Tools worked with grails 1.0 but doesn't work with the current 1.2.1 due to issues getting the JAR dependencies. It also seems that Cloud Tools has been succeeded by Cloud Foundry which is in beta, will cost extra money and has limited places (I signed up but haven't got an e-mail). Question My application is painfully trivial, it has a small load, small data requirements and doesn't need to scale past 5 users. How can I deploy my grails app as quickly and painlessly as possible? Specifically: Are there any hosting companies that have tomcat installed on their servers out of the box that I can sign up to and use that will just work? Do you know of any simple tutorials for getting a grails application deployed to EC2 without Cloud Tools? Thanks in advance, Gav Side-note: I picked grails because of good advice from SO, it should have been a very short time from development to deployed product except the tools for auto-deployment aren't that mature and I've never configured a server before.
