  • JSF vs Stripes, which is best?

    - by Davoink
    Which is best, or in other words, whish is easiest to use? Stripes or JSF. Although I haven't used both in anger I need to gauge what is the best option to work with for both starting new projects and converting existing Struts projects. I have a fear that JSF won't render as nicely as I want but what are others experiences? Seems Stripes is far more straight forward, would I be correct in this assumption? Cheers.

  • Drools Rules: How can I use a method on "when" section?

    - by manoelhc
    Hi, I need to execute a method on "when" section of a DSLR file and I´m not sure if it´s possible. Example: rule "WNPRules_10" when $reminder:Reminder(source == "HMI") $user:User(isInAgeRange("30-100")==true) Reminder(clickPercentual >= 10) User(haveAtLeastOptIns("1,2,3,4") == true) then $reminder.setPriority(1);update($reminder); end (note: isInAgeRange() and haveAtLeastOptIns() are methods of User) I tried with eval() and no errors appeared, but it didn´t execute. Like this: rule "WNPRules_10" when $reminder:Reminder(source == "HMI") $user:User(eval($user.isInAgeRange("30-100")==true)) Reminder(clickPercentual >= 10) User(eval($user.haveAtLeastOptIns("1,2,3,4") == true)) then $reminder.setPriority(1);update($reminder); end How can I resolve this problem?

  • SimpleDateFormat give inconsistent results

    - by Julien Gagnet
    I am trying to parse a date and I am getting different results when I run the code locally/BST compare to a server in Paris/CEST. I've reproduced the issue in a the following sample. This is trying to parse the start date for the Australian Grand Prix. TimeZone tz = TimeZone.getTimeZone("AET"); DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy HH mm"); dateFormat.setTimeZone(tz); long time = dateFormat.parse("28/03/2010 17 00").getTime(); System.out.println("Time "+time); It seems like I am setting the timezone correctly on the date format and the current timezone shouldn't be affecting the code. But locally it prints 1269756000000 and in Paris 1269759600000. Any idea?

  • Hibernate MySQL transaction configuration issue

    - by James
    I'm having trouble starting a transaction with Hibernate and MySQL while running in JUnit. I'm getting a HibernateException which states: "No TransactionManagerLookup specified". I believe this error is because I don't have a proper configuration setting for hibernate.transaction.manager_lookup_class. I see that under the namespace of org.hibernate.transaction there are quite a few different lookup classes that I could use. All of the documentation that I could find on these was very vague. My question is what is the appropriate one for MySQL?

  • Atomikos with Hibernate will exhaust db connections

    - by peter
    I am testing an application (Spring 2.5, Hibernate 3.5.0 Beta, Atomikos 3.6.2, and Postgreql 8.4.2) with the configuration for the DAO listed below. The problem that I see is that the pool of 10 connections with the dataSource gets exhausted after the 10's transaction. I know 'hibernate.connection.release_mode' has no effect unless the session is obtained with openSession rather then using a contextual session. I am wandering if anyone has found a way to instruct atomikos code to release connections after any transaction.

  • Best way to fetch data from a single database table with multiple threads?

    - by Ravi Bhatt
    Hi, we have a system where we collect data every second on user activity on multiple web sites. we dump that data into a database X (say MS SQL Server). we now need to fetch data from this single table from daatbase X and insert into database Y (say mySql). we want to fetch time based data from database X through multiple threads so that we fetch as fast as we can. Once fetched and stored in database Y, we will delete data from database X. Are there any best practices on this sort of design? any specific things to take care on table design like sharing or something? Are there any other things that we need to take care to make sure we fetch it as fast as we can from threads running on multiple machines? Thanks in advance! Ravi

  • Why is ContextConfiguration location different in idea and eclipse

    - by jakob
    Hello experts. In my team we work both in Eclipse and Idea. That works pretty good, except for one minor issue that I can't figure out how to solve. When setting the ContextConfiguration location in our tests and running them inside Eclipse everything works like a charm: @Test(groups = { "database" }) @ContextConfiguration(locations = {" file:src/main/webapp/WEB-INF/applicationContext.xml" }) But in my Idea env I get "could not find applicationContext" error. I need to set the location like this(project name is services): @Test(groups = { "database" }) @ContextConfiguration(locations = {" file:services/src/main/webapp/WEB-INF/applicationContext.xml" }) The project structure is like this: parent.pom with two child poms: services.pom and other.pom. When running the test in the terminal from the service project like this: mvn -Dtest=com.mytest.service.somepackage.TheTest test there are no issues. I guess that since my project structure is parent-with-two-children the need of /service is necessary(The project is created by pointing out the parent pom). Is there a way to fix this? Could you please help me with a solution. thx

  • Use of Hibernate 3.0 with EJB 3.0 & JPA

    - by SOA Nerd
    Where I'm working the guys that are sitting across from me are working on a project. This is a JavaEE app which uses Struts, Spring, EJB 3.0, JPA, and Hibernate 3.0. They are using EJB 3.0 entity beans with annotations. I've been asking them why Hibernate 3.0 is in this mix and noone can seem to tell me. It feels like they've included Hibernate 3.0 because they were told to but are not using it for anything that they can't get from EJB 3.0 entity beans/JPA. They're using CMP and accessing all of the database functions via EJBs. Can Hibernate give you anything in this setup that can't be provided by EJB 3.0/JPA?

  • Ultimate Get/Post with Android Thread for Dummies

    - by Jayomat
    Hi, I'm writing an app to check for the bus timetable's. Therefor I need to post some data to a html page, submit it, and parse the resulting page with htmlparser. Though it may be asked a lot, can some one help me identify if 1) this page does support post/get (I think it does) 2) which fields I need to use? 3) How to make the actual request? this is my code so far: String url = "http://busspur02.aseag.de/bs.exe?Cmd=RV&Karten=true&DatumT=30&DatumM=4&DatumJ=2010&ZeitH=&ZeitM=&Suchen=%28S%29uchen&GT0=&HT0=&GT1=&HT1="; String charset = "CP1252"; System.out.println("startFrom: "+start_from); System.out.println("goTo: "+destination); //String tag.v List<NameValuePair> params = new ArrayList<NameValuePair>(); params.add(new BasicNameValuePair("HTO", start_from)); params.add(new BasicNameValuePair("HT1", destination)); params.add(new BasicNameValuePair("GTO", "Aachen")); params.add(new BasicNameValuePair("GT1", "Aachen")); params.add(new BasicNameValuePair("DatumT", day)); params.add(new BasicNameValuePair("DatumM", month)); params.add(new BasicNameValuePair("DatumJ", year)); params.add(new BasicNameValuePair("ZeitH", hour)); params.add(new BasicNameValuePair("ZeitM", min)); UrlEncodedFormEntity query = new UrlEncodedFormEntity(params, charset); HttpPost post = new HttpPost(url); post.setEntity(query); InputStream response = new DefaultHttpClient().execute(post).getEntity().getContent(); // Now do your thing with the facebook response. String source = readText(response,"CP1252"); Log.d(TAG_AVV,response.toString()); System.out.println("STREAM "+source); One person also gave me a hint to use firebug to read what's going on at the page, but I don't really understand what to look for, or more precisely, how to use the provided information. I also find it confusing, for example, that when I enter the data by hand, the url says, for example, "....HTO=Kaiserplatz&...", but in Firebug, the same Kaiserplatz is connected to a different field, in this case: \<\td class="Start3" Kaiserplatz <\/td (I inserted \ to make it visible) The last line in my code prints the html page, but without having send a request.. it's printed as if there was no input at all... My app is almost done, I hope someone can help me out to finish it! thanks in advance

  • Hibernate ScrollableResults Do Not Return The Whole Set of Results

    - by mlaverd
    Some of the queries we run have 100'000+ results and it takes forever to load them and then send them to the client. So I'm using ScrollableResults to have a paged results feature. But we're topping at roughly 50k results (never exactly the same amount of results). I'm on an Oracle9i database, using the Oracle 10 drivers and Hibernate is configured to use the Oracle9 dialect. I tried with the latest JDBC driver (ojdbc6.jar) and the problem was reproduced. We also followed some advice and added an ordering clause, but the problem was reproduced. Here is a code snippet that illustrates what we do: Criteria crit = sess.createCriteria(ABC.class); crit.add(Restrictions.eq("property", value)); crit.setFetchSize(pageSize); crit.addOrder(Order.asc("property")); ScrollableResults sr = crit.scroll(); ... ... do{ for (Object entry : page) sess.evict(entry); //to avoid having our memory just explode out of proportion page.clear(); for (int i =0 ; i < pageSize && ! metLastRow; i++){ if (resultSet.next()) page.add(sr.get(0)); else metLastRow = true; } metLastRow = metLastRow?metLastRow:sr.isLast(); sendToClient(page); }while(!metLastRow); So, why is it that I get the result set to tell me its at the end when it should be having so much more results?

  • tomcat axis2 shared libs and spring destroy-method problem

    - by EugeneP
    in tomcat\lib there are axis*, axis2* jars. I cannot delete them [sysadmin won't allow to do that]. My web-app invokes web-services. I put Jax-ws jars directly to myapp/web-inf/lib. so inner calls frow a web app servlets use jax-ws libraries. but since "destroy-method" of the bean invokes a web-service, and session is destroyed, then spring makes a service call through tomcat/lib/* = axis2 libraries, and not by using web-inf/lib/jax-ws* How to: a) while not deleting axis2 libs from shared tomcat folder b) make spring use jax-ws libraries to make a web-service call ?

  • HttpURLConnection: Is it necessary to call connect()?

    - by stormin986
    Many examples I've seen don't explicitly call connect(). Instead they just use getInputStream() or getResponseCode(). I'm assuming all of these HttpURLConnection methods that require a connection just call connect() themselves? Are there any cases where connect() must be explicitly called for an HttpURLConnection?

  • Creating multiple log files of different content with log4j

    - by Daniel
    Is there a way to configure log4j so that it outputs different levels of logging to different appenders? I'm trying to set up multiple log files. The main log file would catch all INFO and above messages for all classes. (In development, it would catch all DEBUG and above messages, and TRACE for specific classes.) Then, I would like to have a separate log file. That log file would catch all DEBUG messages for a specific subset of classes, and ignore all messages for any other class. Is there a way to get what I'm after? Thanks, Dan

  • Including a JSP Page Programatically

    - by Tom Tucker
    I need to include a JSP page in a Tag class. I believe the standard way to include a JSP page within another JSP page using API is this: request.getRequestDispatcher("included.jsp").include(request, response); However, I noticed that the included page is rendered at the top of the generated page, no matter where the code is located. On the other hand, the <jsp:include> action works as expected, rendering the included page where the tag appears in the JSP file. How do I include a JSP page in a class so that it behaves the same as the <jsp:include>? There's no way to invoke the <jsp:include> action within a Tag class, is there?

  • Spring MVC Best Practice Handling Unrecoverable Exceptions In Controller

    - by jboyd
    When you have a controller that does logic with services and DAO's that may throw an unrecoverable exception, what is the best practice in dealing with those method calls? Currently an app I'm working on has very lengthy try catch methods that simply err.out exception messages, this doesn't seem very robust and I think that this code smells, is there any cookie cutter best practice for handling this in spring-mvc?
