  • Why a EDT violation happens?

    - by Roman
    I started to use CheckThreadViolationRepaintManager to detect EDT violations. It complains about: partner = getParameter("partner",generatePartnerSelectionPanel(),Design.partnerSelectionDuration); Because it does not like generatePartnerSelectionPanel() because it does not like JPanel panel = new JPanel(); in this method. But I cannot find out why there should be a problem around that. In more details, generatePartnerSelectionPanel() generates a JPanel (I do it not in the EDT) but then, in the getParameter I add the JPanel to the main JFrame and I do it in the EDT (using invokeLater). So, why there should be a problem?

  • Should my internal API classes be all in one package?

    - by Chris
    I'm hard at work packaging up an API for public consumption. As such I'm trying to limit the methods that are exposed to only those that I wish to be public and supportable. Underneath this of course there are a multitude of limited access methods. The trouble is that I have a lot of internal code that needs to access these restricted methods without making those methods public. This creates two issues: I can't create interfaces to communicate between classes as this would make these my internal methods public. I can't access protected or default methods unless I put the majority of my internal classes in the same package. So, I have around 70 or 80 internal classes in cleanly segregated packages BUT with overly permissive access modifiers. Would you say that a single package is the lesser of two evils or is there a better way to be able to mask my internal methods whilst keeping more granular packages? I'd be interested to find out the best practice here. I'm already aware of This

  • Get email address from OpenId using Jboss/Seam

    - by Andy
    I'm using the org.jboss.seam.security.openid.OpenId class to login user's to my seam webapp. Currently I'm saving the validatedId (openid.getValidatedId()) into the database, and asking the user to provide their own email address and first and last name after logging in. I'm using Google, Yahoo, AOL, and MyOpenID for the openId Providers. Is there any way to retrieve the email address and or first/last name of the user without having them enter this in manually?

  • Hibernate: Walk millions of rows and don't leak memory

    - by Autocracy
    The below code functions, but Hibernate never lets go of its grip of any object. Calling session.clear() causes exceptions regarding fetching a joined class, and calling session.evict(currentObject) before retrieving the next object also fails to free the memory. Eventually I exhaust my heap space. Checking my heap dumps, StatefulPersistenceContext is the garbage collector's root for all references pointing to my objects. public class CriteriaReportSource implements JRDataSource { private ScrollableResults sr; private Object currentObject; private Criteria c; private static final int scrollSize = 10; private int offset = 1; public CriteriaReportSource(Criteria c) { this.c = c; advanceScroll(); } private void advanceScroll() { // ((Session) Main.em.getDelegate()).clear(); this.sr = c.setFirstResult(offset) .setMaxResults(scrollSize) .scroll(ScrollMode.FORWARD_ONLY); offset += scrollSize; } public boolean next() { if (sr.next()) { currentObject = sr.get(0); if (sr.isLast()) { advanceScroll(); } return true; } return false; } public Object getFieldValue(JRField jrf) throws JRException { Object retVal = null; if(currentObject == null) { return null; } try { retVal = PropertyUtils.getProperty(currentObject, jrf.getName()); } catch (Exception ex) { Logger.getLogger(CriteriaReportSource.class.getName()).log(Level.SEVERE, null, ex); } return retVal; } }

  • how to import other schema jars when using the scomp tool

    - by MikeJiang
    there is a huge amount of xml schemas for the business, some of them are common types like Money.xsd, Address.xsd, etc, while others are business specific like Customer.xsd, ShippingOrder.xsd, etc. So I decide to compile these schemas into 2 jars, one is commonbeans.jar, the other is businessbeans.jar. I've separated them into different folders. to build the commonbeans.jar is simple, just run "scomp -out commonbeans.jar ....\common*.xsd"; while run "scomp -out businessbeans.jar ....\business*.xsd" is a different story, there are errors say can't find those common types, and run "scomp -out businessbeans.jar ....\business*.xsd ....\business*.xsd" will blindly duplicate all the common types into the businessbeans.jar. so is there any way to link the commonbeans.jar when compile those busimess schemas, maybe something like "scomp -out businessbeans.jar ....\business*.xsd commonbeans.jar". I hope my poor english has expressed my issue!

  • how to invoke a webservice from one container in another container in glassfish

    - by vinny
    I have webservices deployed on two containers in two separate servers A and B. A webMethod in 'Server A' needs to invoke a webmethod in 'Server B'. I have created a client stub for Sever B. Im trying to make 'Server A' use this client stub and talk to Server B. I get an exception while trying to instantiate the port object specifically at : service.getABCBeanPort(); (using JAX-WS library) Is my approach correct? Is there any better way of invoking a webservice on a remote server?

    Hi all. I want to do search in PostgreSQL for INTEGER based columns. if (!sSearch.isEmpty()) { sSearch = sSearch.replaceAll("[^a-zA-Z0-9]", "_").toLowerCase(); String[] search = sSearch.split(" "); sWhere = " "; for (NewsColumns column : NewsColumns.values()) { for (String s : search) { sWhere += "lower(" + column + "::TEXT) LIKE '%" + s + "%' OR "; } } sWhere = sWhere.substring(0,sWhere.length()-3); } Ok, I want to convert INT value to String before search, with '::TEXT' expression. But after executing I'm getting: org.hibernate.QueryException: Not all named parameters have been set: [:TEXT] [select * from news WHERE lower(ID::TEXT) LIKE '%5%' Exception. Looks like hibernate parse my convert exp as parameter. Any help is appreciated. Thanks.

  • How to Implement Custom List View for the list Items in Android Application

    - by avadhani
    I had a problem with the list view having both parent list and the child list of the list activity(implemented through database query). I wish to show them differing their properties by changing the text style (parent list items are in bold, child list items are in normal style). The following is the code from which all the child and parent list items having the same style(bold): String sql = "SELECT Parentid,Childid,Name from (select com.Parentid, com.Childid, com.Name from table1 mem inner join table2 cd on mem.column1=cd.column1 inner join table3 com on com.childid = mem.childid where Parentid is NULL UNION SELECT com.Parentid, com.Childid,com.Name from table1 mem inner join table3 com on com.childid = mem.childid inner join table2 cd on mem.column1=cd.column1 where Parentid is NOT NULL) a group by Parentid, Childid;"; Cursor cdata = myDbHelper.getView(sql); and the List Adapter is: private static final String fields[] = {"Name"}; int[] names = new int[] {R.id.name}; SimpleCursorAdapter adapter2 = new SimpleCursorAdapter(this,R.layout.clientlist1, cdata, fields,names ); and the clientlist.xml is: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/MainLayout" android:padding="5px"> <TextView android:id="@+id/name" android:layout_alignParentRight="true" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textSize="12sp" android:textColor="#104082" android:textStyle="bold" android:layout_weight="1" /> From this i am getting the list having the complete list having both parent and child list items in a single list view. I wish to differ in their text style(bold, normal) for parent and child items respectively. Please help me with the code/links. Thanks a lot in advance.

  • Why does DataInputStream not support integers?

    - by Jason
    I need to read in a list of numbers from a file, none of which are larger than 32767. Originally I was going to use the Scanner class to pull in the data, then I read about DataInputStream. This would work well for me, except that according to the API, it supports all primitive variables EXCEPT ints! Listed are longs, shorts, bytes, chars, booleans, ect, but no ints. I have no need for double precision from the incoming data. Is this a deliberate or unintentional oversight?

  • Parsing custom time format with SimpleDateFormat

    - by ggrigery
    I'm having trouble parsing a date format that I'm getting back from an API and that I have never seen (I believe is a custom format). An example of a date: /Date(1353447000000+0000)/ When I first encountered this format it didn't take me long to see that it was the time in milliseconds with a time zone offset. I'm having trouble extracting this date using SimpleDateFormat though. Here was my first attempt: String weirdDate = "/Date(1353447000000+0000)/"; SimpleDateFormat sdf = new SimpleDateFormat("'/Date('SSSSSSSSSSSSSZ')/'"); Date d1 = sdf.parse(weirdDate); System.out.println(d1.toString()); System.out.println(d1.getTime()); System.out.println(); Date d2 = new Date(Long.parseLong("1353447000000")); System.out.println(d2.toString()); System.out.println(d2.getTime()); And output: Tue Jan 06 22:51:41 EST 1970 532301760 Tue Nov 20 16:30:00 EST 2012 1353447000000 The date (and number of milliseconds parsed) is not even close and I haven't been able to figure out why. After some troubleshooting, I discovered that the way I'm trying to use SDF is clearly flawed. Example: String weirdDate = "1353447000000"; SimpleDateFormat sdf = new SimpleDateFormat("S"); Date d1 = sdf.parse(weirdDate); System.out.println(d1.toString()); System.out.println(d1.getTime()); And output: Wed Jan 07 03:51:41 EST 1970 550301760 I can't say I've ever tried to use SDF in this way to just parse a time in milliseconds because I would normally use Long.parseLong() and just pass it straight into new Date(long) (and in fact the solution I have in place right now is just a regular expression and parsing a long). I'm looking for a cleaner solution that I can easily extract this time in milliseconds with the timezone and quickly parse out into a date without the messy manual handling. Anyone have any ideas or that can spot the errors in my logic above? Help is much appreciated.

  • Maven: add a dependency to a jar by relative path

    - by flybywire
    I have a proprietary jar that I want to add to my pom as a dependency. But I don't want to add it to a repository. The reason is that I want my usual maven commands such as mvn compile, etc, to work out of the box. (Without demanding from the developers a to add it to some repository by themselves). I want the jar to be in a 3rdparty lib in source control, and link to it by relative path from the pom.xml file. Can this be done? How?
