• How to Configure SSL over Database in Spring?

  - by Sameer Malhotra

  Hi, I want to add SSL security in the Database layer. I am using Struts2.1.6, Spring 2.5, JBOSS 5.0 and Informix 11.5. Any idea how to do this? I have researched through a lot on the internet but could not find any solution. Please suggest! Here is my datasource and entity manager beans which is working perfect without SSL: <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> <property name="database" value="INFORMIX" /> <property name="showSql" value="true" /> </bean> </property> </bean> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="com.informix.jdbc.IfxDriver" /> <property name="url" value="jdbc:informix-sqli://SERVER_NAME:9088/DB_NAME:INFORMIXSERVER=SERVER_NAME;DELIMIDENT=y;" /> <property name="username" value="username" /> <property name="password" value="password" /> <property name="minIdle" value="2" /> </bean> <bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean" lazy-init="false"> <property name="targetObject" ref="dataSource" /> <property name="targetMethod" value="addConnectionProperty" /> <property name="arguments"> <list> <value>characterEncoding</value> <value>UTF-8</value> </list> </property> </bean> <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate" scope="prototype"> <property name="dataSource" ref="dataSource" /> </bean> <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <tx:annotation-driven transaction-manager="transactionManager" />

• reCaptcha issue with Spring MVC

  - by skip

  Hi I've been trying to integrate reCaptcha with my application built on Spring framework, but I am getting this error: org.springframework.web.bind.MissingServletRequestParameterException: Required String parameter 'recaptcha_challenge_field' is not present Could someone help me understand that why am I getting this error. I've got both recaptcha_challenge_field and recaptcha_response_field parameters bound to the User domain object. Could anybody help me understand what am I missing? Thanks Here is the code of the controller I am using, all I am trying to do is register a user with reCaptcha functionality but what I am getting is a http status 400 with the error org.springframework.web.bind.MissingServletRequestParameterException: Required String parameter 'recaptcha_challenge_field' is not present: UserManagementController.java @Controller public class UserManagementController { private static final String RECAPTCHA_HTML = "reCaptchaHtml"; @Autowired private UserService userService; @Autowired private ReCaptcha reCaptcha; @RequestMapping(method=RequestMethod.GET, value="/addNewUser.do") public ModelAndView addNewUser() { User user = new User(); String html = reCaptcha.createRecaptchaHtml(null, null); ModelMap modelMap = new ModelMap(); modelMap.put("user", user); modelMap.put(RECAPTCHA_HTML, html); return new ModelAndView("/addNewUser", modelMap); } @RequestMapping(method=RequestMethod.POST, value="/addNewUser.do") public String addNewUser(@Valid User user, BindingResult result, @RequestParam("recaptcha_challenge_field") String challenge, @RequestParam("recaptcha_response_field") String response, HttpServletRequest request, Model model) { verifyBinding(result); String remoteAddr = request.getRemoteAddr(); ReCaptchaResponse reCaptchaResponse = reCaptcha.checkAnswer(remoteAddr, challenge, response); if (!reCaptchaResponse.isValid()) { result.rejectValue("captcha", "errors.badCaptcha"); } model.addAttribute("user", user); if (result.hasErrors()) { result.reject("form.problems"); return "addNewUser"; } return "redirect:showContent.do"; } @InitBinder public void initBinder(WebDataBinder binder) { binder.setAllowedFields(new String[] { "firstName", "lastName", "email", "username", "password", "recaptcha_challenge_field", "recaptcha_response_field" }); } private void verifyBinding(BindingResult result) { String[] suppressedFields = result.getSuppressedFields(); if (suppressedFields.length > 0) { throw new RuntimeException("You've attempted to bind fields that haven't been allowed in initBinder(): " + StringUtils.join(suppressedFields, ", ")); } } } Here is the addNewUser.jsp element on the form page for the above controller: <tr> <td>Please prove you're a person</td> <td>${reCaptchaHtml}</td> <td><form:errors path="captcha" cssStyle="color:red"></form:errors></td> </tr> Could you help me understand what am I missing here?

• Fill a list from JSP in Spring

  - by Javi

  Hello, I have something like this in my Spring Application: public class Book{ public Book(){ sheets = new LinkedList<Sheet>(); } protected List<Sheet> sheets; //getter and setter } I add several Sheets to the sheet list and I print a form in a JSP like this: <form:form modelAttribute="book" action="${dest_url}" method="POST"> <c:forEach items="${mybook.sheets}" var="sheet" varStatus="status"> <form:hidden path="sheet[${status.count -1}].header"/> <form:hidden path="sheet[${status.count -1}].footer"/> <form:hidden path="sheet[${status.count -1}].operador"/> <form:hidden path="sheet[${status.count -1}].number"/> <form:hidden path="sheet[${status.count -1}].lines"/> </c:forEach> ... </form:form> I need to get back this list in the controller when the form is submitted. So in my controller I have a method with a parameter like this: public String myMethod (@ModelAttribute("book") Book book, Model model){ ... } The problem is that it doesn't fill the sheets list unless in the constructor of Book I add as much Sheet's as I want to get. The problem is that I don't know in advance the number of Sheets the book is going to have. I think the problem is that in my method it instantiates Book which has a list of sheets with 0 elements. When it tries to access to sheets[0] the list is empty and it doen't add a Sheet. I've tried to create a getter method for the list with an index parameter (so it can create the element if it doesn't exists in the list like in Struts framework) like this one: public Sheet getSheets(int index){ if(sheets.size() <= index){ Sheet sheet = new Sheet(); sheets.add(index, sheet); } Sheet sheetToReturn = sheets.get(index); if(sheetToReturn == null){ sheetToReturn = new Sheet(); sheets.add(index, sheetToReturn); } return sheetToReturn; } but with this method the JSP doesn't work because sheets has an invalid getter. What's the proper way of filling a list when you don't know the number of items in advanced? Thanks

• Dependency injection: Scoping by region (Guice, Spring, Whatever)

  - by Itay

  Here's a simplified version of my needs. I have a program where every B object has its own C and D object, injected through Guice. In addition an A object is injected into every C and D objects. What I want: that for each B object, its C and D objects will be injected with the same A object. Specifically, I want the output of the program (below) to be: Created C0 with [A0] Created D0 with [A0] Created B0 with [C0, D0] Created C1 with [A1] Created D1 with [A1] Created B1 with [C1, D1] Where it currently produces the following output: Created C0 with [A0] Created D0 with [A1] <-- Should be A0 Created B0 with [C0, D0] Created C1 with [A2] <-- Should be A1 Created D1 with [A3] <-- Should be A1 Created B1 with [C1, D1] I am expecting DI containers to allow this kind of customization but so far I had no luck in finding a solution. Below is my Guice-based code, but a Spring-based (or other DI containers-based) solution is welcome. import java.util.Arrays; import com.google.inject.*; public class Main { public static class Super { private static Map<Class<?>,Integer> map = new HashMap<Class<?>,Integer>(); private Integer value; public Super(Object... args) { value = map.get(getClass()); value = value == null ? 0 : ++value; map.put(getClass(), value); if(args.length > 0) System.out.println("Created " + this + " with " + Arrays.toString(args)); } @Override public final String toString() { return "" + getClass().getSimpleName().charAt(0) + value; } } public interface A { } public static class AImpl extends Super implements A { } public interface B { } public static class BImpl extends Super implements B { @Inject public BImpl(C c, D d) { super(c,d); } } public interface C { } public static class CImpl extends Super implements C { @Inject public CImpl(A a) { super(a); } } public interface D { } public static class DImpl extends Super implements D { @Inject public DImpl(A a) { super(a); } } public static class MyModule extends AbstractModule { @Override protected void configure() { bind(A.class).to(AImpl.class); bind(B.class).to(BImpl.class); bind(C.class).to(CImpl.class); bind(D.class).to(DImpl.class); } } public static void main(String[] args) { Injector inj = Guice.createInjector(new MyModule()); inj.getInstance(B.class); inj.getInstance(B.class); } }

• Spring webflow 1.0 - Downloading a file

  - by Dave

  I am using spring webflow 1.0. I am uploading a csv file, parsing it, and displying results before proceeding. The user has an option to download a csv file that contains the records that did not pass validation. When I click the link in a JSP to download this file, webflow invokes a form Action. The form action writes out a file via getting the output stream off the response: HttpServletResponse response = ((ServletExternalContext) context.getExternalContext()).getResponse(); I do not want to leave the jsp I'm currently on. I just want to download the file. In other words, I do not want to transition to another state. I just want to serve the dynamically rendered file. Everything works (I don't leave the page, and I download the file), but I'm getting the following error in my console: _pEncydKfggPHJo8=org.springframework.webflow.engine.NoMatchingTransitionException: No transition was matched on the event(s) signaled by the [1] action(s) that executed in this action state 'downloadErrorReportAction' of flow 'myFlow'; transitions must be defined to handle action result outcomes -- possible flow configuration error?

• Performance tuning of a Hibernate+Spring+MySQL project operation that stores images uploaded by user

  - by Umar

  Hi I am working on a web project that is Spring+Hibernate+MySQL based. I am stuck at a point where I have to store images uploaded by a user into the database. Although I have written some code that works well for now, but I believe that things will mess up when the project would go live. Here's my domain class that carries the image bytes: @Entity public class Picture implements java.io.Serializable{ long id; byte[] data; ... // getters and setters } And here's my controller that saves the file on submit: public class PictureUploadFormController extends AbstractBaseFormController{ ... protected ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response, Object command, BindException errors) throws Exception{ MutlipartFile file; // getting MultipartFile from the command object ... // beginning hibernate transaction ... Picture p=new Picture(); p.setData(file.getBytes()); pictureDAO.makePersistent(p); // this method simply calls getSession().saveOrUpdate(p) // committing hiernate transaction ... } ... } Obviously a bad piece of code. Is there anyway I could use InputStream or Blob to save the data, instead of first loading all the bytes from the user into the memory and then pushing them into the database? I did some research on hibernate's support for Blob, and found this in Hibernate In Action book: java.sql.Blob and java.sql.Clob are the most efficient way to handle large objects in Java. Unfortunately, an instance of Blob or Clob is only useable until the JDBC transaction completes. So if your persistent class defines a property of java.sql.Clob or java.sql.Blob (not a good idea anyway), you’ll be restricted in how instances of the class may be used. In particular, you won’t be able to use instances of that class as detached objects. Furthermore, many JDBC drivers don’t feature working support for java.sql.Blob and java.sql.Clob. Therefore, it makes more sense to map large objects using the binary or text mapping type, assuming retrieval of the entire large object into memory isn’t a performance killer. Note you can find up-to-date design patterns and tips for large object usage on the Hibernate website, with tricks for particular platforms. Now apparently the Blob cannot be used, as it is not a good idea anyway, what else could be used to improve the performance? I couldn't find any up-to-date design pattern or any useful information on Hibernate website. So any help/recommendations from stackoverflowers will be much appreciated. Thanks

• Spring.Net Message Selectors with compound statements don't seem to be working

  - by Jonathan Beerhalter

  I'm using Spring.NET to connect to ActiveMQ and do some fairly simple pub sub routing. Everything works fine when my selector is a simple expression like Car='Honda' but if I try a compound expression like Car='Honda' AND Make='Pilot' I never get any matches on my subscription. Here's the code to generate the subscription, does anyone see where I might be doing something wrong? public bool AddSubscription(string topicName, Dictionary<string,string> selectorList, GDException exp) { try { ActiveMQTopic topic = new ActiveMQTopic(topicName); string selectorString = ""; if (selectorList.Keys.Count == 0) { // Select all items for this topic selectorString = "2>1"; } else { foreach (string key in selectorList.Keys) { selectorString += key + " = '" + selectorList[key] + "'" + " AND "; } selectorString = selectorString.Remove(selectorString.Length - 5, 5); } IMessageConsumer consumer = this._subSession.CreateConsumer(topic, selectorString, false); if (consumer != null) { _consumers.Add(consumer); consumer.Listener += new MessageListener(HandleRecieveMessage); return true; } else { exp.SetValues("Error adding subscription, null consumer returned"); return false; } } catch (Exception ex) { exp.SetValues(ex); return false; } } And then the code to send the message, which seems simple enough to me public void SendMessage(GDPubSubMessage messageToSend) { if (!this.isDisposed) { if (_producers.ContainsKey(messageToSend.Topic)) { IBytesMessage bytesMessage = this._pubSession.CreateBytesMessage(messageToSend.Payload); foreach (string key in messageToSend.MessageProperties.Keys) { bytesMessage.Properties.SetString(key, messageToSend.MessageProperties[key]); } _producers[messageToSend.Topic].Send(bytesMessage, false, (byte)255, TimeSpan.FromSeconds(1)); } else { ActiveMQTopic topic = new ActiveMQTopic(messageToSend.Topic); _producers.Add(messageToSend.Topic, this._pubSession.CreateProducer(topic)); IBytesMessage bytesMessage = this._pubSession.CreateBytesMessage(messageToSend.Payload); foreach (string key in messageToSend.MessageProperties.Keys) { bytesMessage.Properties.SetString(key, messageToSend.MessageProperties[key]); } _producers[messageToSend.Topic].Send(bytesMessage); } } else { throw new ObjectDisposedException(this.GetType().FullName); } } 07/102009: Update Ok, found the problem bytesMessage.Properties.SetString(key, messageToSend.MessageProperties[key]); This justs sets a single property, so my messages are only being tagged with a single property, hence the combo subscription never gets hit. Anyone know how to add more properties? You'd think bytesMessage.Properties would have a Add method, but it doesn't.

• Spring's JdbcDaoSupport (using MySQL Connector/J) fails after executing sql that adds FK

  - by John

  I am using Spring's JdbcDaoSupport class with a DriverManagerDataSource using the MySQL Connector/J 5.0 driver (driverClassName=com.mysql.jdbc.driver). allowMultiQueries is set to true in the url. My application is an in-house tool we recently developed that executes sql scripts in a directory one-by-one (allows us to re-create our schema and reference table data for a given date, etc, but I digress). The sql scripts sometime contain multiple statements (hence allowMultiQueries), so one script can create a table, add indexes for that table, etc. The problem happens when including a statement to add a foreign key constraint in one of these files. If I have a file that looks like... --(column/constraint names are examples) CREATE TABLE myTable ( fk1 BIGINT(19) NOT NULL, fk2 BIGINT(19) NOT NULL, PRIMARY KEY (fk1, fk2) ); ALTER TABLE myTable ADD CONSTRAINT myTable_fk1 FOREIGN KEY (fk1) REFERENCES myOtherTable (id) ; ALTER TABLE myTable ADD CONSTRAINT myTable_fk2 FOREIGN KEY (fk2) REFERENCES myOtherOtherTable (id) ; then JdbcTemplate.execute throws an UncategorizedSqlException with the following error message and stack trace: Exception in thread "main" org.springframework.jdbc.UncategorizedSQLException: StatementCallback; uncategorized SQLException for SQL [ THE SQL YOU SEE ABOVE LISTED HERE ]; SQL state [HY000]; error code [1005]; Can't create table 'myDatabase.myTable' (errno: 150); nested exception is java.sql.SQLException: Can't create table 'myDatabase.myTable' (errno: 150) at org.springframework.jdbc.support.AbstractFallbackSQLExceptionTranslator.translate(AbstractFallbackSQLExceptionTranslator.java:83) at org.springframework.jdbc.support.AbstractFallbackSQLExceptionTranslator.translate(AbstractFallbackSQLExceptionTranslator.java:80) at org.springframework.jdbc.support.AbstractFallbackSQLExceptionTranslator.translate(AbstractFallbackSQLExceptionTranslator.java:80) and the table and foreign keys are not inserted. Also, especially weird: if I take the foreign key statements out of the script I showed above and then place them in their own script that executes after (so I now have 1 script with just the create table statement, and 1 script with the add foreign key statements that executes after that) then what happens is: tool executes create table script, works fine, table is created tool executes add fk script, throws the same exception as seen above (except errno=121 this time), but the FKs actually get added (!!!) In other words, when the create table/FK statements are in the same script then the exception is thrown and nothing is created, but when they are different scripts a nearly identical exception is thrown but both things get created. Any help on this would be greatly appreciated. Please let me know if you'd like me to clarify anything more.

• Another Spring + Hibernate + JPA question

  - by Albinoswordfish

  I'm still struggling with changing my Spring Application to use Hibernate with JPA to do database activities. Well apparently from a previous post I need an persistence.xml file. However do I need to make changes to my current DAO class? public class JdbcProductDao extends Dao implements ProductDao { /** Logger for this class and subclasses */ protected final Log logger = LogFactory.getLog(getClass()); public List<Product> getProductList() { logger.info("Getting products!"); List<Product> products = getSimpleJdbcTemplate().query( "select id, description, price from products", new ProductMapper()); return products; } public void saveProduct(Product prod) { logger.info("Saving product: " + prod.getDescription()); int count = getSimpleJdbcTemplate().update( "update products set description = :description, price = :price where id = :id", new MapSqlParameterSource().addValue("description", prod.getDescription()) .addValue("price", prod.getPrice()) .addValue("id", prod.getId())); logger.info("Rows affected: " + count); } private static class ProductMapper implements ParameterizedRowMapper<Product> { public Product mapRow(ResultSet rs, int rowNum) throws SQLException { Product prod = new Product(); prod.setId(rs.getInt("id")); prod.setDescription(rs.getString("description")); prod.setPrice(new Double(rs.getDouble("price"))); return prod; } } } Also my Product.Java is below public class Product implements Serializable { private int id; private String description; private Double price; public void setId(int i) { id = i; } public int getId() { return id; } public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } public Double getPrice() { return price; } public void setPrice(Double price) { this.price = price; } public String toString() { StringBuffer buffer = new StringBuffer(); buffer.append("Description: " + description + ";"); buffer.append("Price: " + price); return buffer.toString(); } } I guess my question would be, How would my current classes change after using Hibernate + JPA with an Entity Manager

• Hibernate/Spring: getHibernateTemplate().save(...) Freezes/Hangs

  - by ashes999

  I'm using Hibernate and Spring with the DAO pattern (all Hibernate dependencies in a *DAO.java class). I have nine unit tests (JUnit) which create some business objects, save them, and perform operations on them; the objects are in a hash (so I'm reusing the same objects all the time). My JUnit setup method calls my DAO.deleteAllObjects() method which calls getSession().createSQLQuery("DELETE FROM <tablename>").executeUpdate() for my business object table (just one). One of my unit tests (#8/9) freezes. I presumed it was a database deadlock, because the Hibernate log file shows my delete statement last. However, debugging showed that it's simply HibernateTemplate.save(someObject) that's freezing. (Eclipse shows that it's freezing on HibernateTemplate.save(Object), line 694.) Also interesting to note is that running this test by itself (not in the suite of 9 tests) doesn't cause any problems. How on earth do I troubleshoot and fix this? Also, I'm using @Entity annotations, if that matters. Edit: I removed reuse of my business objects (use unique objects in every method) -- didn't make a difference (still freezes). Edit: This started trickling into other tests, too (can't run more than one test class without getting something freezing) Transaction configuration: <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <tx:advice id="txAdvice" transaction-manager="txManager"> <!-- the transactional semantics... --> <tx:attributes> <!-- all methods starting with 'get' are read-only --> <tx:method name="get*" read-only="true" /> <tx:method name="find*" read-only="true" /> <!-- other methods use the default transaction settings (see below) --> <tx:method name="*" /> </tx:attributes> </tx:advice> <!-- my bean which is exhibiting the hanging behavior --> <aop:config> <aop:pointcut id="beanNameHere" expression="execution(* com.blah.blah.IMyDAO.*(..))" /> <aop:advisor advice-ref="txAdvice" pointcut-ref="beanNameHere" /> </aop:config>

• ejabberd won't look at my host_config option

  - by John

  I'm new with ejabberd. What I want is to have a host myhost.domain.com which has an ldap authentication method. This all works fine if i modify the global options in AUTHENTICATION section in my ejabberd.cfg file. I am able to create two clients( defined in my LDAP directory ), and comunicate between them. Like i said, this works fine. But by aplying this authentication method globaly, it means that every hostname that i declare must use that. So i'm looking at {host_config, "myhost.domain.com" ...} But somehow i can't get ejabberd to look at that configuration, it just skips it. If i declare it like: {xhost_config, ...}, than in my ejabberd.log file i get a bad return error( so it knows that the configuration is there, but it won't look at it). Any suggestions? Thanks.

  I am putting together an Intranet for a company - I have set up authentication to get into the Intranet from a login box linked to AD via LDAP/ However the client wants (if possible) to have users automatically authenticate into the intranet if they are logged into the domain. AD and IIS7.5 are on separate servers (in the same network). I believe that I need to use WindowsAuthentication to do this - but will that work? as the web server is not part of the domain: do I need to tell IIS where the AD server is? The next part could be more complex: once the user has authenticated, I need to drag user details from AD about the user, I guess with LDAP, however I will need to know the user's username in order to do this, won't I? as the user hast had to type this in, how do I get that? The intranet site is in asp.net 4 VB.

• Java JPA Hibernate Spring @EntityListeners throws org.springframework.dao.DataIntegrityViolationException

  - by user

  I am using Spring 3 with Hibernate 3. I would like to update the last modification date automatically when an entity is updated. Below is the sample code: HibernateConfig: @Configuration public class HibernateConfig { @Bean public DataSource dataSource() throws Exception { DriverManagerDataSource dataSource = new DriverManagerDataSource(); Properties properties = new Properties(); properties.load(ClassLoader.getSystemResourceAsStream(new String("hibernate.properties"))); dataSource.setUrl(properties.getProperty(new String("jdbc.url"))); dataSource.setUsername(properties.getProperty(new String("jdbc.username"))); dataSource.setPassword(properties.getProperty(new String("jdbc.password"))); dataSource.setDriverClassName(properties.getProperty(new String("jdbc.driverClassName"))); return dataSource; } @Bean public AnnotationSessionFactoryBean sessionFactory() throws Exception { AnnotationSessionFactoryBean sessionFactory = new AnnotationSessionFactoryBean(); Properties hibernateProperties = new Properties(); Properties properties = new Properties(); properties.load(ClassLoader.getSystemResourceAsStream(new String("hibernate.properties"))); // set the Hibernate Properties hibernateProperties.setProperty(new String("hibernate.dialect"), properties.getProperty(new String("hibernate.dialect"))); hibernateProperties.setProperty(new String("hibernate.show_sql"), properties.getProperty(new String("hibernate.show_sql"))); hibernateProperties.setProperty(new String("hibernate.hbm2ddl.auto"), properties.getProperty(new String("hibernate.hbm2ddl.auto"))); sessionFactory.setDataSource(dataSource()); sessionFactory.setHibernateProperties(hibernateProperties); sessionFactory.setAnnotatedClasses(new Class[]{Message.class}) return sessionFactory; } @Bean public HibernateTemplate hibernateTemplate() throws Exception { HibernateTemplate hibernateTemplate = new HibernateTemplate(); hibernateTemplate.setSessionFactory(sessionFactory().getObject()); return hibernateTemplate; } } DAOConfig: @Configuration public class DAOConfig { @Autowired private HibernateConfig hibernateConfig; @Bean public MessageDAO messageDAO() throws Exception { MessageDAO messageDAO = new MessageHibernateDAO(hibernateConfig.hibernateTemplate()); return messageDAO; } } Message: import java.util.Date; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.EntityListeners; import javax.persistence.Table; import javax.persistence.Temporal; import javax.persistence.TemporalType; import java.io.Serializable; import javax.persistence.Column; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; @Entity @Table @EntityListeners(value = MessageListener.class) public class Message implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column private int id; @Column(nullable = false) @Temporal(TemporalType.TIMESTAMP) private Date lastMod; public Message() { } public int getId() { return id; } public void setId(int id) { this.id = id; } public Date getLastMod() { return lastMod; } public void setLastMod(Date lastMod) { this.lastMod = lastMod; } } MessageListener: import java.util.Date; import javax.persistence.PrePersist; import javax.persistence.PreUpdate; import org.springframework.stereotype.Component; @Component public class MessageListener { @PrePersist @PreUpdate public void setLastMod(Message message) { message.setLastMod(new Date()); } } When running this the MessageListener is not being invoked.

• Encoding problem using Spring MVC

  - by Makis Arvanitis

  Hi all, I have a demo web application that creates users. When I try to insert data in other languages (like french) the characters are not encoded correctly. The code on the controller is: @SuppressWarnings("unchecked") @RequestMapping(value = "/user/create.htm", params={"id"}, method = RequestMethod.GET) public String edit(@RequestParam("id") Long id, ModelMap model) { System.out.println("id is " + id); User user = userService.get(id); model.put("user", user); return "user/create"; } @RequestMapping(value = "/user/create.htm", method = RequestMethod.POST) public String save(@ModelAttribute("user") User user, BindingResult result) { System.out.println(user.getFirstName()); System.out.println(user.getLastName()); validator.validate(user, result); if(result.hasErrors()) { return "user/create"; } userService.save(user); return "redirect:list.htm"; } my web.xml is: ... <filter> <filter-name>encoding-filter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encoding-filter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> ... and the page is: <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %> <%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> ... <form:form method="post" commandName="user"> ... <form:input path="firstName" cssErrorClass="form-error-field"/> ... when I enter some french characters in the first name then the output from the system.out.println is ????+????? or something similar. I saw other people fixing this with the CharacterEncodingFilter but this doesn't seem to work. Thanks a lot. Edited the filter value.

• Spring, Hibernate, Blob lazy loading

  - by Alexey Khudyakov

  Dear Sirs, I need help with lazy blob loading in Hibernate. I have in my web application these servers and frameworks: MySQL, Tomcat, Spring and Hibernate.

I'm trying to display on a web page database records related to files, which was saved in MySQL database. All works fine if a volume of data is small. But the volume of data is big I'm recieving an error "java.lang.OutOfMemoryError: Java heap space" I've tried to write in blobFields null values on each row of table. In this case, application works fine, memory doesn't go out of. I have a conclusion that the blob field which is marked as lazy (@Basic(fetch=FetchType.LAZY)) isn't lazy, actually! How can I solve the issie? Many thanks for advance.

• Character-encoding problem spring

  - by aelshereay

  Hi All, I am stuck in a big problem with encoding in my website! I use spring 3, tomcat 6, and mysql db. I want to support German and Czech along with English in my website, I created all the JSPs as UTF-8 files, and in each jsp I include the following: <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> I created messages.properties (the default which is Czech), messages_de.properties, and messages_en.properties. And all of them are saved as UTF-8 files. I added the following to web.xml: <filter> <filter-name>encodingFilter</filter-name> <filterclass> org.springframework.web.filter.CharacterEncodingFilter</filterclass> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <locale-encoding-mapping-list> <locale-encoding-mapping> <locale>en</locale> <encoding>UTF-8</encoding> </locale-encoding-mapping> <locale-encoding-mapping> <locale>cz</locale> <encoding>UTF-8</encoding> </locale-encoding-mapping> <locale-encoding-mapping> <locale>de</locale> <encoding>UTF-8</encoding> </locale-encoding-mapping> </locale-encoding-mapping-list> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> And add the following to my applicationContext.xml: <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource" p:basenames="messages"/> <!-- Declare the Interceptor --> <mvc:interceptors> <bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" p:paramName="locale" /> </mvc:interceptors> <!-- Declare the Resolver --> <bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver" /> I set the useBodyEncodingForURI attribute to true in the element of server.xml under: %CATALINA_HOME%/conf, also another time tried to add URIEncoding="UTF-8" instead. I created all the tables and fields with charset [utf8] and collection [utf8_general_ci] The encoding in my browser is UTF-8 (BTW, I have IE8 and Firefox 3.6.3) When I open the MYSQL Query browser and insert manually Czech or German data, it's being inserted correctly, and displayed correctly in my app as well. So, here's the list of problems I have: By default the messages.properties (Czech) should load, instead the messages_en.properties loads by default. In the web form, when I enter Czech data, then click submit, in the Controller I print out the data in the console before to save it to db, what's being printed is not correct having strange chars, and this is the exact data that saves to db. I don't know where's the mistake! Why can't I get it working although I did what people did and worked for them! don't know.. Please help me, I am stuck in this crappy problem since days, and it drives me crazy! Thank you in advance.

• Spring hibernate ehcache setup

  - by Johan Sjöberg

  I have some problems getting the hibernate second level cache to work for caching domain objects. According to the ehcache documentation it shouldn't be too complicated to add caching to my existing working application. I have the following setup (only relevant snippets are outlined): @Entity @Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE public void Entity { // ... } ehcache-entity.xml <cache name="com.company.Entity" eternal="false" maxElementsInMemory="10000" overflowToDisk="true" diskPersistent="false" timeToIdleSeconds="0" timeToLiveSeconds="300" memoryStoreEvictionPolicy="LRU" /> ApplicationContext.xml <bean class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="ds" /> <property name="annotatedClasses"> <list> <value>com.company.Entity</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.generate_statistics">true</prop> <prop key="hibernate.cache.use_second_level_cache">true</prop> <prop key="net.sf.ehcache.configurationResourceName">/ehcache-entity.xml</prop> <prop key="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.SingletonEhCacheRegionFactory</prop> .... </property> </bean> Maven dependencies <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-annotations</artifactId> <version>3.4.0.GA</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-hibernate3</artifactId> <version>2.0.8</version> <exclusions> <exclusion> <artifactId>hibernate</artifactId> <groupId>org.hibernate</groupId> </exclusion> </exclusions> </dependency> <dependency> <groupId>net.sf.ehcache</groupId> <artifactId>ehcache-core</artifactId> <version>2.3.2</version> </dependency> A test class is used which enables cache statistics: Cache cache = cacheManager.getCache("com.company.Entity"); cache.setStatisticsAccuracy(Statistics.STATISTICS_ACCURACY_GUARANTEED); cache.setStatisticsEnabled(true); // store, read etc ... cache.getStatistics().getMemoryStoreObjectCount(); // returns 0 No operation seems to trigger any cache changes. What am I missing? Currently I'm using HibernateTemplate in the DAO, perhaps that has some impact. [EDIT] The only ehcache log output when set to DEBUG is: SettingsFactory: Cache region factory : net.sf.ehcache.hibernate.SingletonEhCacheRegionFactory

• Migrate Spring JPA DAO unit testing to google app engine

  - by twingocerise

  I'm trying to put together a simple environment where I can get Spring, Maven, JPA, Google App Engine and DAO unit testing working happily all together. The goal is to be able to run a simple DAO unit test creating an entity and then load it again with a simple find to check it's been created properly - all of this from my maven build. My dao is making use of the JPA entity manager (query(), persist(), etc.) I've got it working no problem with hsqldb and a datasource, etc. but I'm struggling to get it working with appengine. My questions are: 1) I'm using an entity manager, injecting my persistence unit as followed. Is it OK? Is there any need for a datasource or something special? I thought not but correct me if I'm wrong. applicationContext.xml <bean id='entityManagerFactory' class='org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean'> <property name="persistenceUnitName" value="transactions-optional" /> </bean> Persistence.xml <persistence-unit name="transactions-optional"> <provider>org.datanucleus.store.appengine.jpa.DatastorePersistenceProvider</provider> <properties> <property name="datanucleus.NontransactionalRead" value="true"/> <property name="datanucleus.NontransactionalWrite" value="true"/> <property name="datanucleus.ConnectionURL" value="appengine"/> </properties> </persistence-unit> 2) what are the dependencies I need to add to my pom file to be able to run the unit test making use of the entityManager? What about versions ? I found loads of things about appengine-api-labs/stubs/testing but none them got it working i.e. I'm getting jdo dependency missing while I'm using JPA... I also get loads of conflicts when I try to add some jars (datanucleus and stuff). So far I'm trying appengine-api-1.0-sdk v1.7.0 - ASM-all v3.3 - datanucleus core/api-jpa/enhancer v3.1.0 - datanucleus-appengine v2.0.1.1 and all the gae testing jars v1.7.0 3) Is there anything I need to add to my surefire plugin (test runner) to make sure it picks up all the dependencies? I'm getting an exhausting ClassNotFound on DatastorePersistenceProvider while it is in my classpath (I checked the jars and the mvn dependency:tree) I had a look at this but it doesn't seem to be working at all: http://www.vertigrated.com/blog/2011/02/working-maven-3-google-app-engine-plugin-with-gwt-support/ 4) Do I need to use any sot of localhelper to test my DAOs? Ideally I'd want to test my dao layer "as is" with the entity manager... what's your opinion ? Has anyone managed to run a unit test using JPA on google app engine ? 5) Do I need to set up any sort of gae.home somewhere in my pom file? Would anyone make use of it (a plugin or something) ? 6) Is the gwt-maven plugin any helpful if I don't use gwt - I'm writing a simple webservice making use of appengine, not a GWT app... Any help would be much appreciated as I've been struggling for 2 days now... Cheers, V.

• can bind successfully to the ldap server, but needs to know how to find user w/i AD

  - by Brad

  I create a login form to bind to the ldap server, if successful, it creates a session (which the user's username is stored within), then I go to another page that has session_start(); and it works fine. What I want to do now, is add code to test if that user is a member of a specific group. So in theory, this is what I want to do if(username session is valid) { search ldap for user -> get list of groups user is member of foreach(group they are member of) { switch(group) { case STAFF: print 'they are member of staff group'; $access = true; break; default: print 'not a member of STAFF group'; $access = false; break; } if(group == STAFF) { break; } } if($access == TRUE) { // you have access to the content on this page } else { // you do not have access to this page } } How do I do a ldap_search w/o binding? I don't want to keep asking for their password on each page, and I can't pass their password thru a session. Any help is appreciated.

• How to make Spring accept fluent (non-void) setters?

  - by Chris

  Hi, I have an API which I am turning into an internal DSL. As such, most methods in my PoJos return a reference to this so that I can chain methods together declaratively as such (syntactic sugar). myComponent .setID("MyId") .setProperty("One") .setProperty2("Two") .setAssociation(anotherComponent) .execute(); My API does not depend on Spring but I wish to make it 'Spring-Friendly' by being PoJo friendly with zero argument constructors, getters and setters. The problem is that Spring seems to not detect my setter methods when I have a non-void return type. The return type of this is very convenient when chaining together my commands so I don't want to destroy my programmatic API just be to compatible with Spring injection. Is there a setting in Spring to allow me to use non-void setters? Chris

• Large ResultSet on postgresql query

  - by tuler

  I'm running a query against a table in a postgresql database. The database is on a remote machine. The table has around 30 sub-tables using postgresql partitioning capability. The query will return a large result set, something around 1.8 million rows. In my code I use spring jdbc support, method JdbcTemplate.query, but my RowCallbackHandler is not being called. My best guess is that the postgresql jdbc driver (I use version 8.3-603.jdbc4) is accumulating the result in memory before calling my code. I thought the fetchSize configuration could control this, but I tried it and nothing changes. I did this as postgresql manual recomended. This query worked fine when I used Oracle XE. But I'm trying to migrate to postgresql because of the partitioning feature, which is not available in Oracle XE. My environment: Postgresql 8.3 Windows Server 2008 Enterprise 64-bit JRE 1.6 64-bit Spring 2.5.6 Postgresql JDBC Driver 8.3-603
