  • Cannot parse persistence unit from class path resource

    - by Grzegorz S
    so I have this problem in running my Spring WS app which implements JPA ( or should implement..) I have a problem with running a WS, it looks like my Spring context can't find file persistence.xml Which i am able to believe because i did not have generated META-INF folder in my template (which is Maven project template with archetype org.springframework.ws) I have created META-INF manually.

  • How to override TOMCAT Oracle ojdbc14 driver in the application?

    - by Luís Henrique Rocha
    The TOMCAT server is using an Oracle 9G ojdbc14 driver to its jndi connections in the /common/lib folder. My web application uses Maven + Spring and I'm getting the dataSource using Spring jndi features. I'm trying to bypass TOMCAT old ojdbc14 driver with a newer one (ojdbc14 10.2.0.4.0). I've tried putting the jars in the WEB-INF/lib folder as a project dependency, but it doesn't work the application keeps using the old oracle driver that is in the TOMCAT folder. I'm trying to bypass the TOMCAT oracle driver because I cannot update it to the newest version because there are lots of other projects using it. Does anyone have a clue?

  • Freemarker template not found

    - by brock
    Hi, I'm currently trying to get Freemarker to work with my application using Spring. No matter what I try I keep getting template not found. I am not sure if I have the configuration set up properly, but it never finds my template. Here is my spring bean config: <bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer"> <property name="templateLoaderPath" value="/WEB-INF/freemarker/"/> </bean> Whenever I try to call getTemplate on the freemaker configuration it always sends back a template not found error. So if I do configuration.getTemplate("testTemplate.ftl") it always throws an IOException. I'm not sure if anyone has an idea of what I'm doing wrong. Thanks for all your help!

  • Unbelievable: Cannot cast from class X to its super class

    - by Phuong Nguyen de ManCity fan
    I'm encountering a very weird problem with Spring (3.0.1.RELEASE), TestNG (5.11) and Maven Surefire (2.5). I have a test class that extends a Spring helper class for testNG so that test context can be loaded from an xml file (that contains some bean definitions). My project was imported into eclipse using m2eclipse (using Import Maven Project) The class run fine in Eclipse TestNG runner. However, it throws this exception with Maven Surefire Caused by: java.lang.ClassCastException: com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl cannot be cast to javax.xml.parsers.DocumentBuilderFactory at javax.xml.parsers.DocumentBuilderFactory.newInstance(DocumentBuilderFactory.java:123) at org.springframework.beans.factory.xml.DefaultDocumentLoader.createDocumentBuilderFactory(DefaultDocumentLoader.java:89) at org.springframework.beans.factory.xml.DefaultDocumentLoader.loadDocument(DefaultDocumentLoader.java:70) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:388) I have eliminated all involved dependencies in my pom so that the two classes com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl and javax.xml.parsers.DocumentBuilderFactory are coming from JRE only (the rt.jar). So, it looks so unbelievable to me. I wonder if there is any mechanism in loading class that can explain for this behavior? Thanks.

  • Properties framework in java apps

    - by Roman
    Hi All I have been using spring for a while as my IOC. It has also a very nice way of injecting properties in your beans. Now I am participating in a new project where the IOC is Guice. I dont understand fully the concept how should I inject properties in to my beans using Guice. The question : Is it actually possible to inject raw properties ( strings , ints ) into my guice beans. If the answer is no , than maybe you know some nice Properties Framework for java. Because right now I wanted to use the ResourceBundle class for simple properties management in my app. But after using spring for a while this just dont seem seriously enought for me.

  • iPhone plist data, large amounts of text and return key?

    - by user278342
    Basicly iv built my app using a plist. But with the data there is a few times when I need to press return and start a new line. The return key doesn't work in the plist. If I did it the older way it would be \n\n but that doesn't work either. Is there a obvious way I'm overlooking? Or will it be a case off just pressing the space bar allot? Thanks

  • Can an Aspect conditionally render parts of a JSP page ?

    - by Scott The Scot
    At present the jsp pages have normal authorize tags to conditionally render links and information etc. The website is on the intranet, and we're using Spring Security 2.0.4. Ive now got a business user who wants to allow all roles to access everything for the first few weeks, then gradually add the security back in as feedback is gathered from the business. Rather than go through every page, removing the authorize tags, only to have to put them back in, is is possible to configure these through an aspect, or is there any other way to externalize this into a config file ? I've found Spring's MethodSecurityInterceptor and the meta data tags, but these wouldn't give me the externalization. I've been on google for the last hour, and am now pretty sure this can't be done, but would love to find out I haven't been asking the right questions. Advice appreciated

  • How to remove/hide Atomikos startup error message?

    - by HDave
    When Atomikos is configured via Spring, a jta.properties or transactions.properties file is not needed. Nonetheless, Atomikos starts up with the follow messages printed to stderr: No properties path set - looking for transactions.properties in classpath... transactions.properties not found - looking for jta.properties in classpath... Failed to open transactions properties file - using default values It makes it look like the Spring configuration didn't take -- although apparently everything is fine. Does anyone know how to get rid of this so I don't end up getting asked about it 1.000 times?

  • Good book suggestions for building enterprise software

    - by ncoder
    Enterprise software are built using technologies/softwares/terminologies/APIs such as EJB, JBoss, Seam, Hibernate(JPA), Maven, Eclipse, Spring, JTS, JMS, JNDI etc. I know there are great books out there for each of these individually, however can someone suggest a book or two that covers all (or most of) these topics in lesser detail and gives examples of how these are integrated? I have intentionally left the client side stuff out because its highly unlikely a single book would cover that much. If anyone knows of a book (or books) that cover most of or various combinations (like EJB, Hibernate, Spring and Seam) of these technologies, please do suggest the same. The idea is not to become an expert in all however know about them in reasonable detail and why each one is required.

  • Crashes in Core Data's Inferred Mapping Model Creation (Lightweight Migration). Threading Issue?

    - by enchilada
    I'm getting random crashes when creating an inferred mapping model (with Core Data's lightweight migration) within my application. By the way, I have to do it programmatically in my application while it is running. This is how I create this model (after I have made proper currentModel and newModel objects, of course): NSMappingModel *mappingModel = [NSMappingModel inferredMappingModelForSourceModel:currentModel destinationModel:newModel error:&error]; The problem is this: This method is crashing randomly. When it works, it works just fine without issues. But when it crashes, it crashes my application (instead of returning nil to signify that the method failed, as it should). By randomly, I mean that sometimes it happens and sometimes not. It is unpredictable. Now, here is the deal: I'm running this method in another thread. More precisely, it is located inside a block that is passed via GCD to run on the global main queue. I need to do this for my UI to appear crisp to the user, i.e. so that I can display a progress indicator while the work is underway. The strange thing seems to be that if I remove the GCD stuff and just let it run on the main thread, it seems to be working fine and never crashing. Thus, could it be because I'm running this on a different thread that this is crashing? I somehow find that weird because I don't believe I'm breaking any Core Data rules regarding multi-threading. In particular, I'm not passing any managed objects around, and whenever I need access to the MOC, I create a new MOC, i.e. I'm not relying on any MOC (or for that matter: anything) that has been created earlier on the main thread. Besides the little MOC stuff that occurs, occurs after the mapping model creation method, i.e. after the point at which the app crashes, so it can't possibly be a cause of the crashes under consideration here. All I'm doing is taking two MOMs and asking for a mapping model between them. That can't be wrong even under threading, now can it? Any ideas on what could be going on?

  • Does this data structure have a name? Sort of a "linked matrix"?

    - by Bob
    Let's say I wanted similar functionality to a doubly linked list but needed a matrix instead so that each node was structured like this: public class Node { Node Up, Down, Left, Right; object Value; } Is there a name for such a structure? I've looked through this Wikipedia listing of data structures but didn't see anything similar. Unless I just missed it.

  • How to deal with databases for websites written in Java, more specifically Wicket?

    - by John
    Hi there. I'm new to website development using Java but I've got started with Wicket and make a little website. I'd like to expand on what I've already made (a website with a form, labels and links) and implement database connectivity. I've looked at a couple of examples, in example Mystic Paste, and I see that they're using Hibernate and Spring. I've never touched Hibernate or Spring before and to be honest the heavy use of annotations scare me a little bit as I haven't really made use of them before, with the exception of supressing warnings and overriding. At this point I have one Connection object which I set up in the WebApplication class upon initialization. I then retrieve this connection object whenever I need to perform queries. I don't know if this is a bad approach or not for a production web application. All help is greatly appreciated.

  • How to insert into two different tables in one statement with Java and MySQL?

    - by MalcomTucker
    I am using Java, Spring (NamedParameterJdbcTemplate) and MySQL. My statement looks like this: INSERT INTO Table1 (Name) VALUES (?); INSERT INTO Table2 (Path, Table1Id) VALUES (?, LAST_INSERT_ID()) But it is throwing the following error: PreparedStatementCallback; bad SQL grammar [INSERT INTO Table1 (Name) VALUES (?); INSERT INTO Table2 (Path, Table1Id) VALUES (?, LAST_INSERT_ID())] ` Nested exception is: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'INSERT INTO Table2 (Path, Table1Id' at line 1 The syntax works fine in MySQL but something is up when combining via the Spring template. Thanks!

  • Can't get the JSONP workin' with WCF Data Services...

    - by SevilNatas
    What am I missing here? It seems from all that I read and watched, exposing JSON from a WCF Data Service should be as easy as adding the '[JSONPSupportBehavior]' directive in front of the Service Class. Problem is VS2010 doesn't recognize 'JSONPSupportBehavior'. Is there a reference I am missing? Seemed like, from alll the articles, it was supportted outta the box. TIA S.

  • Ajax and sophisticated graphics in Java web-app

    - by EugeneP
    In my opinion WWW will sooner or later come to full-blown AJAX web-sites, so that we wouldn't have page reloads every time you click somewhere. Now I want you to ask this. What tools and frameworks can one use to make a Java Web-application running on Tomcat have AJAX functionality like "in-place, with no page reloading" table sorting by clicking on its column header, multi-tabs that enable opening at once the new screen to the user without reloading a page, saving data in the database without reloading a page, and other similar things that we do not usually see on web pages. That's all should probably be based on AJAX. But how to integrate this AJAX functionality with existing java web-frameworks, let's say Spring MVC? Or maybe there are other frameworks that better suit such needs but that can be integrated with core Spring?
