  • skip-limit ignored for skippable exception thrown from writer

    - by ck
    i am working on a project with spring batch 2.0.2 and have skippable exception set up in the config. for exceptions thrown from the processor everything works fine. it skips and once the limit is execeed the job fails (or stops). for exceptions thrown from the writer (same chunk) it keeps skipping. the skip-limit doesnt seem to matter. maybe i missunderstood and skipping and writer don't go together or maybe i am missing a configuration. does anyone know how to skip issues - with a limit - within the writer properly?

  • Not showing error when calling another function in Spring

    - by Javi
    Hello, I have a controller with 2 methods. The first one just add some lists to the model (the lists of my comboboxes) and return a JSP with a form. The second one validates the data and if there aren't errors it saves the data. The code looks like this: public String showForm(Model model){ //load some data into some lists return "tiles:myJSPfile"; } public String save(@Valid @ModelAttribute("MyData") Data data, BindingResult result, Model model){ if(result.hasErrors()){ //there are errors: show form with error messages //(but I need to reload the combobox lists) return showForm(model); } //save data } The problem is that in this way I don't see the error messages in the form (though I see by the debugger that it has found errors). I've thought that the problem comes because the showForm method doesn't have the error messages because it can't see the BindingResult, so I've added BindingResult as a parameter of showForm method, but it still doesn't work. I've added My Model Attribute as well but I get the same problem. If I just return the JSP file in the save method I can see the errors, but in this way I would need to add again in this other method the lists I had already added in the showForm (duplicated code). I can't save the data in session scope so it's compulsory to get again the lists after getting the error. if(result.hasErrors()){ //there are errors: show form with error messages return "tiles:myJSPfile"; } Why are errors not shown when I call a function to display my JSP different from the one I used for the validation? What's the best way to do this? Thanks.

  • Multi Process Configuration

    - by user200937
    Hi, I have a product built out of multiple processes. Each process uses internally commons configuration. Does anyone have an idea how to manage the config? I.e. we do not want to duplicate variables so each process will be able to read them. Additionally, DB solution is no good, as we do not want to be dependent on DB for something like configuration. Thanks Yair

  • Printing is not working in tomcat, when i start server with services.msc(From client side we could not print )

    - by maya
    I am using JasperReports 1.3.1 to print the report. I am sing eclipse and tomcat for development purpose. In eclipse, when i run the application, the below code will show the listed printer devices and print button. If i click the print button, the report is printing by selected device. PrintRequestAttributeSet printRequestAttributeSet = new HashPrintRequestAttributeSet(); printRequestAttributeSet.add(MediaSizeName.ISO_A5); PrintServiceAttributeSet printServiceAttributeSet = new HashPrintServiceAttributeSet(); JRPrintServiceExporter exporter = new JRPrintServiceExporter(); exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint); exporter.setParameter(JRPrintServiceExporterParameter.PRINT_REQUEST_ATTRIBUTE_SET, printRequestAttributeSet); exporter.setParameter(JRPrintServiceExporterParameter.PRINT_SERVICE_ATTRIBUTE_SET, printServiceAttributeSet); exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PAGE_DIALOG, Boolean.FALSE); exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PRINT_DIALOG, Boolean.TRUE); exporter.exportReport(); Here I am passing jasperPrint as a parameter which i manually construted.Its working good My problem is: I created war file and pasted in tomcat Apache Software Foundation\Tomcat 6.0\webapps directory and started the tomcat by using services.msc. At this point, its not displaying the listed printer details and also not printing. I put some logger, I found that, the code is hanging with exporter.exportReport(); after this line code is not executing . Please suggest me for how to print from client side using jasper

  • Why linking doesn't work in my Xtext-based DSL?

    - by reprogrammer
    The following is the Xtext grammar for my DSL. Model: variableTypes=VariableTypes predicateTypes=PredicateTypes variableDeclarations= VariableDeclarations rules=Rules; VariableType: name=ID; VariableTypes: 'var types' (variableTypes+=VariableType)+; PredicateTypes: 'predicate types' (predicateTypes+=PredicateType)+; PredicateType: name=ID '(' (variableTypes+=[VariableType|ID])+ ')'; VariableDeclarations: 'vars' (variableDeclarations+=VariableDeclaration)+; VariableDeclaration: name=ID ':' type=[VariableType|ID]; Rules: 'rules' (rules+=Rule)+; Rule: head=Head ':-' body=Body; Head: predicate=Predicate; Body: (predicates+=Predicate)+; Predicate: predicateType=[PredicateType|ID] '(' (terms+=Term)+ ')'; Term: variable=Variable; Variable: variableDeclaration=[VariableDeclaration|ID]; terminal WS: (' ' | '\t' | '\r' | '\n' | ',')+; And, the following is a program in the above DSL. var types Node predicate types Edge(Node, Node) Path(Node, Node) vars x : Node y : Node z : Node rules Path(x, y) :- Edge(x, y) Path(x, y) :- Path(x, z) Path(z, y) When I used the generated Switch class to traverse the EMF object model corresponding to the above program, I realized that the nodes are not linked together properly. For example, the getPredicateType() method on a Predicate node returns null. Having read the Xtext user's guide, my impression is that the Xtext default linking semantics should work for my DSL. But, for some reason, the AST nodes of my DSL don't get linked together properly. Can anyone help me in diagnosing this problem?

  • Can I use android.os.* libraries in a standalone project?

    - by medicdave
    I'm trying to develop an external library (not sure if that's the right term) to provide prepackaged functionality in Android projects. Working in Eclipse, I've added the appropriate android.jar file to the build path, and everything is happy both while editing and upon compilation. However, when I use Android's Handler and Message classes (android.os.Handler, android.os.Message) for inter-thread communication, I get exceptions unless I'm running within an Android app, on the emulator or a device. I can no longer test my library in a "standalone" way without having to go through a running Android target. Is there any way for me to include these two Android classes and still be able to test my library standalone? Do I need to have the Android source available? Or would it require some sort of conditional compilation hand-waving?

  • Can't run jUnit with Eclipse

    - by KimKha
    I use new Eclipse. Create demo test with jUnit (I added default jUnit library built-in Eclipse). Then I write this code: import junit.framework.*; import org.junit.Test; public class SimpleTest extends TestCase { public SimpleTest(String name) { super(name); } public final void main(String method){ } @Test public final void testSimpleTest() { int answer = 2; assertEquals((1+1), answer); } } But it doesn't run. In the Debug tab: org.eclipse.jdt.internal.junit.runner.RemoteTestRunner at localhost:52754 Thread [main] (Suspended (exception ClassNotFoundException)) URLClassLoader$1.run() line: not available [local variables unavailable] AccessController.doPrivileged(PrivilegedExceptionAction<T>, AccessControlContext) line: not available [native method] Launcher$AppClassLoader(URLClassLoader).findClass(String) line: not available Launcher$AppClassLoader(ClassLoader).loadClass(String, boolean) line: not available Launcher$AppClassLoader.loadClass(String, boolean) line: not available Launcher$AppClassLoader(ClassLoader).loadClass(String) line: not available How can I solve this?

ContentPane is container that contain JLabel that has contents(text, button, radio etc...). I don't know this is correct T.T Why I ask this is I failed combine the contents. I can not make TextField and InternalFrame at a time. I want to know the concept. I hope you take my question right.

  • GAE/J: unable to register a custom ELResolver

    - by dfa
    I need to register a custom ELResolver for a Google App Engine project. Since it must be registered before any request is received, as specified by the Javadoc: It is illegal to register an ELResolver after the application has received any request from the client. If an attempt is made to register an ELResolver after that time, an IllegalStateException is thrown. I'm using a ServletContextListener: public class RegisterCustomELResolver implements ServletContextListener { @Override public void contextInitialized(ServletContextEvent sce) { ServletContext context = sce.getServletContext(); JspApplicationContext jspContext = JspFactory.getDefaultFactory().getJspApplicationContext(context); jspContext.addELResolver(new MyELResolver()); } ... } The problem is that JspFactory.getDefaultFactory() returns always null. I've alreay filled a bug report. Any idea for a workaround?

  • How to click through JGlassPane With MouseListener to UI behind it

    - by Epicmaster
    I have a JFrame and a bunch of JComponents on top of the JFrame. I need to make use of the JGlassPane and I used this implementation to set it up. JPanel glass = new JPanel(); frame.setGlassPane(glass); glass.setVisible(true); glass.setOpaque(false); After doing so I can't select any JButtons or other JComponents under the JGlassPane. Is there a way to have only the components on the GlassPane selectable while still having the ability to select components under the GlassPane? Edit I forgot to mention (not knowing this would be relevant) that I did attach both a MouseListener and a MouseMotionListener to the glass pane. Is there a way to pass the Mouse Events to other components and only use them when needed?

  • JSF, actionlistener at facelets

    - by asrijaal
    Hi there, I'm using JSF (Mojarra 1.2) with Richfaces (3.3.2) within some facelets which are used as portlets (I'm using the Jboss Portlet Bridge 2.0 here). Now I'm facing something strange: I've got an actionlistener on my <h:commandButton> which is triggered, when the button is clicked but when I simply reload the page, the action is executed everytime I load the page again. This happens only if I already triggered the action before. Is this behaviour normal? I should notice that Spring 2.5 is used to manage my beans, the mentioned beans are session-scope beans, maybe this is a interessting point?!

  • How do you do a limit query in HQL

    - by stevedbrown
    In Hibernate 3, is there a way to do the equivalent of the following MySql limit in HQL. select * from a_table order by a_table_column desc limit 0, 20; I don't want to use setMaxResults if possible. This definitely was possible in the older version of Hibernate/HQL, but seems to have disappeared.

  • How can one extract rdf:about or rdf:ID properties from triples using SPARQL?

    - by lennyks
    It seemed a trivial matter at the beginning but so far I have not managed to get the unique identifier for a given resource using SPARQL. What I mean is given, e.g., rdf:Description rdf:about="http://..." and then some properties identifying this resource, what I want to do is to first find this very resource and then retrieve all the triples given some URI. I have tried naïve approaches by writing statements in a WHERE clause such as: ?x rdf:about ?y and ?x rdfs:about ?y I hope I am being precise.

  • Hibernate orm for a view

    - by EugeneP
    How do you ORM a view? Is there any difference with a table in terms of reverse engineering? In my case, I have a whole pile of joined tables that will be read-only in an application. So, if I need sort of a 1 Object with all collections in proper order, instead of long chains of relationships - collection with another etc, it'll be simpler. What do you think and how do you accomplish this?

  • Does Hibernate create tables in the database automatically.

    - by theJava
    http://www.vaannila.com/spring/spring-hibernate-integration-1.html Upon reading this tutorial, they have not mentioned anything over creating tables in the DB. Does the Hibernate handle it automatically by creating tables and fields once i specify them. Here is my beans configuration. <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp/" p:suffix=".jsp" /> <bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://127.0.0.1:3306/spring"/> <property name="username" value="monwwty"/> <property name="password" value="www"/> </bean> <bean id="mySessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="myDataSource" /> <property name="annotatedClasses"> <list> <value>uk.co.vinoth.spring.domain.User</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.hbm2ddl.auto">create</prop> </props> </property> </bean> <bean id="myUserDAO" class="uk.co.vinoth.spring.dao.UserDAOImpl"> <property name="sessionFactory" ref="mySessionFactory"/> </bean> <bean name="/user/*.htm" class="uk.co.vinoth.spring.web.UserController" > <property name="userDAO" ref="myUserDAO" /> </bean> </beans>

  • 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. :)

  • Android Lightweight HTML Template Engine

    - by Anthoni Gardner
    Hello, I am after a very lightweight template engine that supports / can be embedded inside Android programs. I've looked at the MiniTemplator (I think that is how you spell it) and that looks great but it loads in only from file and I need to load templates from string and I am not fully confident in changing that code lol. Can anyone recommend a very lightweight (preferably no jars, single source files etc) that I can use ? I do not need it to parse XML or anything like, just normal HTML files with keywords embedded into them betwee %% tags etc. Regards Anthoni

  • Axis webservice calls fail sometimes, access.log shows content!

    - by epischel
    Hi, our app is a webservice client (axis 1) to a third party webservice (also axis 1). We use it for some years now. Since a few weeks, we (as a client) get sometimes HTTP status 400 (bad request) or read timeouts when calling the webservice. Strangely, the access.log of the service shows part of the request or the response instead of the URL. It looks like this (looks like the end of the request string) x.x.x.x -> y.y.y.y:8080 - - [timestamp] "POST /webservice HTTP/1.0" 200 16127 0 x.x.x.x -> y.y.y.y:8080 - - [timestamp] "POST /webservice HTTP/1.0" 200 22511 1 x.x.x.x -> y.y.y.y:8080 - - [timestamp] "il=\"true\"/><nsl:text xsi:type=\"xsd:string\" xsi:nil=\"true\"/></SOAPSomeOperation></soapenv:Body></soapenv:Envelope> Axis/1.4" 400 299 0 or (some string out of the what looks like the request) x.x.x.x -> y.y.y.y:8080 - - [timestamp] ":string\">some text</sometag><othertag>moretext" 400 299 0 or in some other cases it looks like two requests thrown together (... means xml string left out): x.x.x.x -> y.y.y.y:8080 - - [timestamp] "...</someop></soapenv:Body></soapenv:Envelope>:xsd=\"http://www.w3.org/2001/XMLSchema\"...</soapenv:Body></soapenv:Envelope>" 400 299 0 Application log does not give any hints. Frequency of such call is 1% of all calls to that service. The only discriminator I know of so far is that it happens since operations informed us that the service url changed because of "server migration". Has anyone experienced such phenomenon yet? Has somebody got an idea whats wrong and how to fix? Thanks,
