  • JBoss 6 unpacks jars from WEB-INF/lib of war

    - by Maxym
    when I start JBoss 6 I see that it unpacks all jar files from WEB-INF/lib in tmp/vfs/automountXXX folder. E.g. jackrabbit-server.war contains library asm-3.1.jar, then in tmp folder I see the following folders with files: asm-3.1.jar-83dc35ead0d41d41/asm-3.1.jar asm-3.1.jar-2a48f1c13ec7f25d/contents/"unpacked asm-3.1.jar" it does not take files from my.ear/lib only WEB-INF/lib... Why is it so? And is here any way to prevent it doing so? It just slows down application server starting (and stopping), what is not that comfortable at development... If it is somehow related to JavaEE 6 specification and ejb-jars, which can be located now in WEB-INF/lib, so I don't have such libraries in my war files... UPDATE: actually when I repack jackrabbit-server.war to jackrabbit-server.ear which contains jackrabbit-server.war and moved all its libraries to jackrabbit-server.ear/lib then I still see two folders in tmp: asm-3.1.jar-215a36131ebb088e/asm-3.1.jar asm-3.1.jar-14695f157664f00/contents/ but in this case last folder is empty. So it still creates two folders, but does not unpack my library. Also I use exploded deployment so the question is only about jar files, not unpacking ear/war.

  • javax.servlet import cannot be resolved after moving web servlet

    - by Michael Kjörling
    I have written a small web servlet to run under Tomcat, using Eclipse Helios. In its old, non-source-controlled location, everything was fine, but now I need to add this to our source control system. Moving the old files out of the way, creating a new workspace, setting up the server connection and copying and importing the existing projects into the new workspace all worked fine once I figured out how to do it, but I can't get the servlet to build. Instead, I get a whole bunch of cannot be resolved to a type errors talking about various servlet class types; HttpServlet, HttpServletRequest, ServletException, etc. Another error that is almost certainly related is The import javax.servlet cannot be resolved. I am obviously missing something very basic, but I'm new to this (and not having the terminology really down pat probably doesn't help me Google for an answer). Any suggestions as to what I might be missing would be greatly appreciated.

  • Why does Hibernate 2nd level cache only cache queries within a session?

    - by Synesso
    Using a named query in our application and with ehcache as the provider, it seems that the query results are tied to the session within the cache. Any attempt to access the value from the cache for a second time results in a LazyInitializationException We have set lazy = true for the following mapping because this object is also used by another part of the system which does not require the reference... and we want to keep it lean. <class name="domain.ReferenceAdPoint" table="ad_point" mutable="false" lazy="false"> <cache usage="read-only"/> <id name="code" type="long" column="ad_point_id"> <generator class="assigned" /> </id> <property name="name" column="ad_point_description" type="string"/> <set name="synonyms" table="ad_point_synonym" cascade="all-delete-orphan" lazy="true"> <cache usage="read-only"/> <key column="ad_point_id" /> <element type="string" column="synonym_description" /> </set> </class> <query name="find.adpoints.by.heading">from ReferenceAdPoint adpoint left outer join fetch adpoint.synonyms where adpoint.adPointField.headingCode = ?</query> Here's a snippet from our hibernate.cfg.xml <property name="hibernate.cache.provider_class">net.sf.ehcache.hibernate.SingletonEhCacheProvider</property> <property name="hibernate.cache.use_query_cache">true</property> It doesn't seem to make sense that the cache would be constrained to the session. Why are the cached queries not usable outside of the (relatively short-lived) sessions?

  • looping problem while appending data to existing text file

    - by Manu
    try { stmt = conn.createStatement(); stmt1 = conn.createStatement(); stmt2 = conn.createStatement(); rs = stmt.executeQuery("select cust from trip1"); rs1 = stmt1.executeQuery("select cust from trip2"); rs2 = stmt2.executeQuery("select cust from trip3"); File f = new File(strFileGenLoc); OutputStream os = (OutputStream)new FileOutputStream(f,true); String encoding = "UTF8"; OutputStreamWriter osw = new OutputStreamWriter(os, encoding); BufferedWriter bw = new BufferedWriter(osw); } while ( rs.next() ) { while(rs1.next()){ while(rs2.next()){ bw.write(rs.getString(1)==null?

"":rs2.getString(1)); bw.write("\t"); bw.newLine(); } } } Above code working fine. My problem is 1. "rs" resultset contains one record in the table 2. "rs1" resultset contains 5 record in the table 3. "rs2" resultset contains 5 record in the table "rs" data is getting recursive. while writing to the same text file , the output i am getting like 1 2 3 1 12 21 1 23 25 1 10 5 1 8 54 but i need output like below 1 2 3 12 21 23 25 10 5 8 54 What things i need to change in my code..

  • How do you create your own drag-n-drop GUI designer ?

    - by panzerschreck
    Hello I was looking at creating a UI for developing web forms, similar to the Netbeans Visual JSF form designer.It will be targeted to use GWT/GXT components.I am looking at a look very similar to VS/Netbeans. Any thoughts on where/how to start ? Initially, I would prefer to have it as a standalone application, later develop it as eclipse plugin. I have already evaluated the extjs designer and the eclipse plugin from instantiations, but i would prefer to have it developed on my own, as it looks challenging, Also, I have few custom components that have been developed. Thanks

  • Apache Wicket exposes attributes

    - by Luke
    I just tried the Apache Wicket "Hello, world" application and I noticed that in the rendered HTML output, Wicket is exposing it's internal attributes. This is what the rendered HTML looks like in the 'view source' of the browser: <html> <body> <span wicket:id="message" id="message">Hello World!</span> </body> </html> How do I get rid of the wicket:id="message" attribute in the rendered HTML output?

  • Intermittent Issue Writing to Google Appengine Datastore

    - by user242153
    Hi, I have a functioning app and recently have had intermittent problems writing to the datastore. I did not make any relevant code changes, however in the last few days my attempts to write to the datastore sometimes work and sometimes don't. I am trying to save an object that is in a many to one relationship with an existing persisted parent. So, the logic works like this: 1) Parent pulled from the datastore 2) Child created / instantiated using constructor 3) Parent.addSingleChild(child); // the "addSingleChild" method just adds the object argument to the collection of children 4) child.setParent(Parent); // sets the Parent object to the parent field I am using transactions as explained in the documentation ending with "finally {if (tx.isActive()) {tx.rollback(); } }" When the servlet is called, the parent is called from the datastore and the child object is created and added to the many to one mapping to the pre-existing parent. The child should automatically be persisted, since the parent is already persistent, and the child is added to the collection of children that map to the parent. And it worked this way in the past. However, to be sure, i did add a pm.makePersistent(child). Doesn't seem to help, still have the intermittent problem. Any suggestions would be appreciated, and if you need to see the actual code I can post. Thanks

  • Android how to create notification that resumes activity

    - by Adam Praiswater
    I a have a notification in a receiver that fires off fine, but it restarts the activity (thus clearing the edittexts and resetting the toggle button) How can i set it so that when its tapped on it resumes the activity rather that clearing and resetting everything? My current code doesnt work. Current Code String currentDateTimeString = DateFormat.getDateTimeInstance().format(new Date()); Intent intenti= new Intent(context, Locator.class); intenti.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intenti, 0); NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context) .setSmallIcon(R.drawable.xxxxxxnotifyicon) .setContentTitle("xxxxxxx Link") .setContentText("Auto Check In Complete at " + currentDateTimeString); mBuilder.setContentIntent(contentIntent); mBuilder.setDefaults(Notification.DEFAULT_SOUND); mBuilder.setAutoCancel(true); NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); mNotificationManager.notify(1, mBuilder.build());

  • Send data from Service to Widget on Android.

    - by Jose Vega
    I am writing a widget on Android 1.6 that shows the minutes that a person has used on the current month. The way I have it setup is by having a service that listens to the state of the phone and when the phone is picked up, it starts the timer and when the person hangs up, ends a timer. I would like to send this variable(long duration) over to my appWidgetProvider so I could update the edit text on it.

  • Type-safe mapping from Class<T> to Thing<T>

    - by Joonas Pulakka
    I want to make a map-kind of container that has the following interface: public <T> Thing<T> get(Class<T> clazz); public <T> void put(Class<T> clazz, Thing<T> thing); The interesting point is that the Ts in each Class<T><- Thing<T> pair is the same T, but the container should be able to hold many different types of pairs. Initially I tried a (Hash)Map. But, for instance, Map<Class<T>, Thing<T>> is not right, because then T would be same T for all pairs in that map. Of course, Map<Class<?>, Thing<?>> works, but then I don't have type-safety guarantees so that when I get(String.class), I can't be sure that I get a Thing<String> instance back. Is there a way to accomplish the kind of type safety that I'm looking for?

  • No Hibernate Exception on the same insert of data

    - by Mark Estrada
    Hi All, Hibernate Newbie here. I am quite unsure why I am not getting any exception when I am executing below code. On first attempt, this code creates the Book Entry on my Book Table. But my concern is that when I execute below code again, no error was pop out by Hibernate. I was in fact expecting some sort of Violation of Primary Key Constraints as what I have bee doing in JDBC code. public class BookDao { public void createBook(Book bookObj) { Session session = HibernateUtil.getSessionFactory() .getCurrentSession(); session.beginTransaction(); session.saveOrUpdate(bookObj); session.getTransaction().commit(); } } public class HibernateUtil { private static final SessionFactory sessionFactory = buildSessionFactory(); private static SessionFactory buildSessionFactory() { try { // Create the SessionFactory from hibernate.cfg.xml return new AnnotationConfiguration().configure() .buildSessionFactory(); } catch (Throwable ex) { // Make sure you log the exception, as it might be swallowed ex.printStackTrace(); throw new ExceptionInInitializerError(ex); } } public static SessionFactory getSessionFactory() { return sessionFactory; } } public class BookDBStarter { public static void main(String[] args) { Book bookHF = new Book(); bookHF.setIsbn("HF-12345"); bookHF.setName("Head First HTML"); bookHF.setPublishDate(new Date()); BookDao daoBook = new BookDao(); daoBook.createBook(bookHF); } } Is this normal hibernate way? And how will I know if my insert is successful? Any thoughts?

  • Scrum stories and behind the scenes features

    - by James P.
    As I understand things, the Scrum backlog is composed of a series of Stories that represent something for the end user and this is further decomposed into Features. If this is the case, where does all the behind the scenes features go that aren't really linked to a story but are still useful? For example, say I'm making an application that catalogs the contents of a hard drive. A story wouldn't require it but having an md5 hash on each file would be a nice feature.

  • Representing element as boolean with JAXB?

    - by Marcus
    We have this XML: <Summary> <ValueA>xxx</ValueA> <ValueB/> </Summary> <ValueB/> will never have any attributes or inner elements. It's a boolean type element - it exists (true) or it doesn't (false). JAXB generated a Summary class with a String valueA member, which is good. But for ValueB, JAXB generated a ValueB inner class and a corresponding member: @XmlElement(name = "ValueB") protected Summary.ValueB valueB; But what I'd like is a boolean member and no inner class: @XmlElement(name = "ValueB") protected boolean valueB; How can you do this? I'm not looking to regenerate the classes, I'd like to just make the code change manually. Update: In line with the accepted answer, we created a new method returning the boolean value conditional on whether valueB == null. As we are using Hibernate, we annotated valueB with @Transient and annotated the boolean getter with Hibernate's @Column annotation.

  • Google App Engine - Cannot See Children in Datastore Viewer

    - by Taylor L
    I have the following kinds/relationships in my datastore: UserAccount 1-to-1 PersistentLogin 1-to-many PersistentLogins They are all in the same entity group and UserAccount is the parent. Should I expect to see the other kinds in the datastore viewer? Currently, I only see UserAccount entities, but I'm pretty confident the other entities are there because my code is working as expected. Is this just a nuance of the datastore viewer?

  • Maven - 'all' or 'parent' project for aggregation?

    - by disown
    For educational purposes I have set up a project layout like so (flat in order to suite eclipse better): -product | |-parent |-core |-opt |-all Parent contains an aggregate project with core, opt and all. Core implements the mandatory part of the application. Opt is an optional part. All is supposed to combine core with opt, and has these two modules listed as dependencies. I am now trying to make the following artifacts: product-core.jar product-core-src.jar product-core-with-dependencies.jar product-opt.jar product-opt-src.jar product-opt-with-dependencies.jar product-all.jar product-all-src.jar product-all-with-dependencies.jar Most of them are fairly straightforward to produce. I do have some problem with the aggregating artifacts though. I have managed to make the product-all-src.jar with a custom assembly descriptor in the 'all' module which downloads the sources for all non-transitive deps, and this works fine. This technique also allows me to make the product-all-with-dependencies.jar. I however recently found out that you can use the source:aggregate goal in the source plugin to aggregate sources of the entire aggregate project. This is also true for the javadoc plugin, which also aggregates through the usage of the parent project. So I am torn between my 'all' module approach and ditching the 'all' module and just use the 'parent' module for all aggregation. It feels unclean to have some aggregate artifacts produced in 'parent', and others produced in 'all'. Is there a way of making an 'product-all' jar in the parent project, or to aggregate javadoc in the 'all' project? Or should I just keep both? Thanks

  • JButton Image Ignoring GridBagConstraints

    - by daemor
    I am working on an application and have a screen that needs to have elements (namely some custom JButtons) appear and disappear based on a user selection. However for some reason, when I add these buttons to their pane, the buttton image goes to the top corner, and leaves the text in the center, completely ignoring GridBagConstraints. I am completely stumped on this one as I have done this same exact thing dozens of times earlier in the program without any issues. Here is an image of the problem: The problem is in this method here, and occurs down towards the bottom. public void init(){ contentPane.removeAll(); // Setup jlabels JLabel countyLabel = new JLabel("County"); countyLabel.setFont(new Font("Times New Roman", Font.PLAIN, 18)); JLabel measureByLabel = new JLabel("Measure By: "); measureByLabel.setFont(new Font("Times New Roman", Font.PLAIN, 18)); String[] countyChoices = {"Washtenaw", "Oakland", "Livingston"}; // setup components JComboBox<String> countyCombo = new JComboBox<String>(countyChoices); // place baseComponents c.weightx = 0.5; c.weighty = 0.5; c.gridx = 0; c.gridy = 0; c.anchor = GridBagConstraints.NORTH; contentPane.add(countyLabel, c); c.gridx = 2; contentPane.add(countyCombo, c); c.gridy = 1; c.gridx = 0; contentPane.add(trenchButton, c); c.gridx = 2; contentPane.add(bedButton, c); c.gridy = 2; c.gridx = 1; contentPane.add(systemSelection, c); c.gridy = 3; c.gridx = 0; contentPane.add(lengthButton, c); c.fill = GridBagConstraints.BOTH; c.gridwidth = 4; c.gridy = 4; c.gridx = 0; contentPane.add(choicePane, c); GridBagConstraints con = new GridBagConstraints(); con.weightx = 0.5; con.weighty = 0.5; con.gridx = 0; con.gridy = 0; choicePane.add(lengthButton, c); // revalidate and repaint choicePane.revalidate(); choicePane.repaint(); contentPane.revalidate(); contentPane.repaint(); } I have tried doing this in separate methods, the button looks fine when added to the contentPane, the pane is for sure set to gridbagconstraints as I used the expression JPanel choicePane = new JPanel(new GridBagLayout()) to initialize it.

  • Synth LaF JLabel DISABLED color

    - by mmoris
    Hi all, Using the Synth LaF, I am unable to set a JLabel's FOREGROUND color for the DISABLED state. has anybody succeeded in doing this? Here is my label's style definition in my LaF.xml file. <style id="whiteLabelStyle"> <opaque value="false"/> <font name="Bitstream Vera Sans" size="16" /> <state> <color type="FOREGROUND" value="WHITE"/> </state> <state value="DISABLED"> <color type="FOREGROUND" value="BLACK"/> </state> </style> <bind style="whiteLabelStyle" type="name" key="WhiteOrbitLabel"/> Please not that all the other styles defined in my LaF.xml file are rendered properly in my application including my label's WHITE normal state color (it just never goes to black when I do lbl.setEnabled(false) Also, going through the Synth code, I have found the following comment in SynthStyle.getColor if ((context.getComponentState() & SynthConstants.DISABLED) != 0) { //This component is disabled, so return the disabled color. //In some cases this means ignoring the color specified by the //developer on the component. In other cases it means using a //specified disabledTextColor, such as on JTextComponents. //For example, JLabel doesn't specify a disabled color that the //developer can set, yet it should have a disabled color to the //text when the label is disabled. This code allows for that. if (c instanceof JTextComponent) { JTextComponent txt = (JTextComponent)c; Color disabledColor = txt.getDisabledTextColor(); if (disabledColor == null || disabledColor instanceof UIResource) { return getColorForState(context, type); } } else if (c instanceof JLabel && (type == ColorType.FOREGROUND || type == ColorType.TEXT_FOREGROUND)){ return getColorForState(context, type); } But I could not figure out how to set a disabled color for a JLabel Thanks for your help!

  • Android Load Camera image as Bitmap

    - by GuyNoir
    I am using BitmapFactory.decodeFile to load Bitmaps of images into my application. However, the function returns null on large images (such as those from the camera). The filepath is definitely correct, I just can't figure out why it would return null. I tried supersampling, but it didn't seem to help. Does anyone have any idea why it would do this or how I could more easily load images taken from the camera into a Bitmap? Thanks.

This should be consider outbound-service right? how to do this?
