• Out of Memory - web applications

  - by Walter White

  Hi all, I am trying to figure out why Jetty 6.1.22 is running out of memory on my laptop. I have 2 web applications running JBoss Seam, Hibernate (with EHCache), and separate Quartz scheduler instances. With little load, the server dies throwing OutOfMemory. What can I look for? Would you think that I am not properly closing handles for input streams or files? I tried profiling my application with Netbeans, but it works off and on. Usually, it ends up locking up even though it doesn't use that much CPU or memory. Walter

• A trigger on hibernate (maybe this is called interceptor)

  - by Ittai

  Hi, I have a module which uses Hibernate as an ORM solution with EHCache as second level cache. I have another seperate module which inserts and updates the database. What I need is to have the ability to trigger an event when a row is inserted or updated. Let's say I have a Customers table and it is mapped to a Customer entity. I want some procedure to notify me that a new Customer has been added. Regarding the second seperate module it uses Hibernate also but at least for the time being they are not connected (I'm pointing this out as if someone thinks that I must share the Hibernate session (or something of the sort) between them then this is something I will consider). Please note that I have limited experience with Hibernate. Thanks in advance

• Configuration for log4j to log ERROR level to a DB table

  - by firnnauriel

  Using the default config of a fresh Grails project, how do i change it so that ONLY error level messages will go to 'Message' table? // log4j configuration log4j = { // Example of changing the log pattern for the default console // appender: // //appenders { // console name:'stdout', layout:pattern(conversionPattern: '%c{2} %m%n') //} error 'org.codehaus.groovy.grails.web.servlet', // controllers 'org.codehaus.groovy.grails.web.pages', // GSP 'org.codehaus.groovy.grails.web.sitemesh', // layouts 'org.codehaus.groovy.grails.web.mapping.filter', // URL mapping 'org.codehaus.groovy.grails.web.mapping', // URL mapping 'org.codehaus.groovy.grails.commons', // core / classloading 'org.codehaus.groovy.grails.plugins', // plugins 'org.codehaus.groovy.grails.orm.hibernate', // hibernate integration 'org.springframework', 'org.hibernate', 'net.sf.ehcache.hibernate' warn 'org.mortbay.log' } Thanks for any leads on this.

• Caching using hibernate

  - by Subhendu Mahanta

  I have 2 applications.First one is a web application through which we provision reference data.Second one is an ESB based application where the reference data is used.The reference data changes but not very frequently.We needed to cache the reference data.The web application( I am not the owner) used hibernate. But my ESB based application did not.We only used EHCache. When reference data is changed by the independent web application that needs to be reflected in ESB application.We implemented using message queue - that is when reference data changes web application sends a message to the message queue.Our ESB application listens to that message & clears the cache & caches the data once again.This works.But it is time intensive.How can I use Hibernate to improve the situation? Regards, Subhendu

• I am trying to figure out the best way to understand how to cache domain objects

  - by Brett Ryan

  I've always done this wrong, I'm sure a lot of others have too, hold a reference via a map and write through to DB etc.. I need to do this right, and I just don't know how to go about it. I know how I want my objects to be cached but not sure on how to achieve it. What complicates things is that I need to do this for a legacy system where the DB can change without notice to my application. So in the context of a web application, let's say I have a WidgetService which has several methods: Widget getWidget(); Collection<Widget> getAllWidgets(); Collection<Widget> getWidgetsByCategory(String categoryCode); Collection<Widget> getWidgetsByContainer(Integer parentContainer); Collection<Widget> getWidgetsByStatus(String status); Given this, I could decide to cache by method signature, i.e. getWidgetsByCategory("AA") would have a single cache entry, or I could cache widgets individually, which would be difficult I believe; OR, a call to any method would then first cache ALL widgets with a call to getAllWidgets() but getAllWidgets() would produce caches that match all the keys for the other method invocations. For example, take the following untested theoretical code. Collection<Widget> getAllWidgets() { Entity entity = cache.get("ALL_WIDGETS"); Collection<Widget> res; if (entity == null) { res = loadCache(); } else { res = (Collection<Widget>) entity.getValue(); } return res } Collection<Widget> loadCache() { // Get widgets from underlying DB Collection<Widget> res = db.getAllWidgets(); cache.put("ALL_WIDGETS", res); Map<String, List<Widget>> byCat = new HashMap<>(); for (Widget w : res) { // cache by different types of method calls, i.e. by category if (!byCat.containsKey(widget.getCategory()) { byCat.put(widget.getCategory(), new ArrayList<Widget>); } byCat.get(widget.getCatgory(), widget); } cacheCategories(byCat); return res; } Collection<Widget> getWidgetsByCategory(String categoryCode) { CategoryCacheKey key = new CategoryCacheKey(categoryCode); Entity ent = cache.get(key); if (entity == null) { loadCache(); } ent = cache.get(key); return ent == null ? Collections.emptyList() : (Collection<Widget>)ent.getValue(); } NOTE: I have not worked with a cache manager, the above code illustrates cache as some object that may hold caches by key/value pairs, though it's not modelled on any specific implementation. Using this I have the benefit of being able to cache all objects in the different ways they will be called with only single objects on the heap, whereas if I were to cache the method call invocation via say Spring It would (I believe) cache multiple copies of the objects. I really wish to try and understand the best ways to cache domain objects before I go down the wrong path and make it harder for myself later. I have read the documentation on the Ehcache website and found various articles of interest, but nothing to give a good solid technique. Since I'm working with an ERP system, some DB calls are very complicated, not that the DB is slow, but the business representation of the domain objects makes it very clumsy, coupled with the fact that there are actually 11 different DB's where information can be contained that this application is consolidating in a single view, this makes caching quite important.

• grails run-war connects to mysql but grails run-war doesn't

  - by damian

  Hi, I have a unexpected problem. I had create a war with grails war. Then I had deployed in Tomcat. For my surprise the crud works fine but I don't know what persistence is using. So I did this test: Compare grails prod run-app with grails prod run-war. The first works fine, and does conect with the mysql database. The other don't. This is my DataSource.groovy: dataSource { pooled = true driverClassName = "com.mysql.jdbc.Driver" username = "grails" password = "mysqlgrails" } hibernate { cache.use_second_level_cache=false cache.use_query_cache=false cache.provider_class='net.sf.ehcache.hibernate.EhCacheProvider' } // environment specific settings environments { development { dataSource { dbCreate = "update" // one of 'create', 'create-drop','update' url = "jdbc:mysql://some-key.amazonaws.com/MyDB" } } test { dataSource { dbCreate = "update" // one of 'create', 'create-drop','update' url = "jdbc:mysql://some-key.amazonaws.com/MyDB" } } production { dataSource { dbCreate = "update" url = "jdbc:mysql://some-key.amazonaws.com/MyDB" } } } Also I extract the war to see if I could find some data source configuration file without success. More info: Grails version: 1.2.1 JVM version: 1.6.0_17 Also I think this question it's similar, but doesn't have a awnser.

• Squid handling of concurrent cache misses

  - by Oliver H-H

  We're using a Squid cache to off-load traffic from our web servers, ie. it's setup as a reverse-proxy responding to inbound requests before they hit our web servers. When we get blitzed with concurrent requests for the same request that's not in the cache, Squid proxies all the requests through to our web ("origin") servers. For us, this behavior isn't ideal: our origin servers gets bogged down trying to fulfill N identical requests concurrently. Instead, we'd like the first request to proxy through to the origin server, the rest of the requests to queue at the Squid layer, and then all be fulfilled by Squid when the origin server has responded to that first request. Does anyone know how to configure Squid to do this? We've read through the documentation multiple times and thoroughly web-searched the topic, but can't figure out how to do it. We use Akamai too and, interestingly, this is its default behavior. (However, Akamai has so many nodes that we still see lots of concurrent requests in certain traffic spike scenarios, even with Akamai's super-node feature enabled.) This behavior is clearly configurable for some other caches, eg. the Ehcache documentation offers the option "Concurrent Cache Misses: A cache miss will cause the filter chain, upstream of the caching filter to be processed. To avoid threads requesting the same key to do useless duplicate work, these threads block behind the first thread." Some folks call this behavior a "blocking cache," since the subsequent concurrent requests block behind the first request until it's fulfilled or timed-out. Thx for looking over my noob question!

• Building asynchronous cache pattern with JSP

  - by merweirdo

  I have a JSP that will take some 8 minutes to render. The code logic itself can not be made more efficient (it will update often and be updated by basically a pointy haired boss). I tried wrapping it with a caching layer like <%@ taglib uri="/WEB-INF/classes/oscache.tld" prefix="oscache" %> <oscache:cache time="60"> <div class="pagecontent"> ..... my logic </div> </oscache:cache> This is nice until the 60 seconds is over. The next query after that blocks until the 8 minutes of rendering is done with again. I would need a way to build a pattern something like: If there is no version of the dynamic content in the cache run the actual logic (and populate the cache for subsequent requests) If there is a non-expired version of the dynamic content in the cache serve the output of the JSP logic from the cache If there is an expired version of the dynamic content in the cache serve the output of the JSP logic still from the cache AND run the JSP logic in the background so that the cache gets updated transparently to the user - avoiding the user have to wait for 8 minutes I found out that at least EHCache might be able to do some asynchronous cache updating but it did not sadly seem to apply to the JSP tags... Also I have to take in 10-20 parameters for the actual logic of the JSP and some of them should be used as a key for caching. Code example and/or pointers would be greatly appreciated. I do not frankly care if the solution provided is extremely ugly. I just want a simple 5 minute caching with asynchronous cache update taking into account some parameters as a key.

• Why does grails use hsqldb when I ask for mysql?

  - by John

  I'm following the racetrack example from Jason Rudolph's book at InfoQ, using grails-1.2.1. I got up to the part where I was to switch from hsqldb to mysql. I think I've deleted every reference to hsqldb in the DataSource.groovy file, but I get an exception and the stack trace shows it's still using hsqldb. DataSource.groovy dataSource { boolean pooled = true String driverClassName = "com.mysql.jdbc.Driver" String url = "jdbc:mysql://localhost/dfpc2" String dbCreate = "create" String username = "dfpc2" String password = "dfpc2" dialect = org.hibernate.dialect.MySQL5InnoDBDialect } hibernate { cache.use_second_level_cache=true cache.use_query_cache=true cache.provider_class='net.sf.ehcache.hibernate.EhCacheProvider' } // environment specific settings environments { development { } test { } production { } } When I grails run-app it all starts up with no errors. I can navigate to the home page. But when I click on one of the links, I get a stack trace: java.sql.SQLException: Table not found in statement [select this_.id as id0_0_, this_.version as version0_0_, this_.name as name0_0_, this_.variant as variant0_0_ from domainObject this_ limit ?] at org.hsqldb.jdbc.Util.throwError(Unknown Source) at org.hsqldb.jdbc.jdbcPreparedStatement.<init>(Unknown Source) at org.hsqldb.jdbc.jdbcConnection.prepareStatement(Unknown Source) at dfpc2.domainObjectController$_closure2.doCall(script1269434425504953491149.groovy:13) at dfpc2.domainObjectController$_closure2.doCall(script1269434425504953491149.groovy) at java.lang.Thread.run(Thread.java:619) My mysql database shows no tables created. (I don't think groovy's connected to mysql yet.) Things I've checked: mysql-connector-java-5.1.6.jar is in lib directory. I've tried grails clean I tried putting the dataSource info in the development environment (I haven't graduated to test or prod yet), but it seemed to make no difference. The stdout shows I'm using development env. I've googled for solutions, but the only solution I've found is when people don't change the test or production environments.

• How to use second level cache for lazy loaded collections in Hibernate?

  - by Chandru

  Let's say I have two entities, Employee and Skill. Every employee has a set of skills. Now when I load the skills lazily through the Employee instances the cache is not used for skills in different instances of Employee. Let's Consider the following data set. Employee - 1 : Java, PHP Employee - 2 : Java, PHP When I load Employee - 2 after Employee - 1, I do not want hibernate to hit the database to get the skills and instead use the Skill instances already available in cache. Is this possible? If so how? Hibernate Configuration <session-factory> <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <property name="hibernate.connection.password">pass</property> <property name="hibernate.connection.url">jdbc:mysql://localhost/cache</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</property> <property name="hibernate.cache.use_second_level_cache">true</property> <property name="hibernate.cache.use_query_cache">true</property> <property name="hibernate.cache.provider_class">net.sf.ehcache.hibernate.EhCacheProvider</property> <property name="hibernate.hbm2ddl.auto">update</property> <property name="hibernate.show_sql">true</property> <mapping class="org.cache.models.Employee" /> <mapping class="org.cache.models.Skill" /> </session-factory> The Entities with imports, getters and setters Removed @Entity @Table(name = "employee") @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) public class Employee { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private int id; private String name; public Employee() { } @ManyToMany @JoinTable(name = "employee_skills", joinColumns = @JoinColumn(name = "employee_id"), inverseJoinColumns = @JoinColumn(name = "skill_id")) @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) private List<Skill> skills; } @Entity @Table(name = "skill") @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) public class Skill { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private int id; private String name; } SQL for Loading the Second Employee and his Skills Hibernate: select employee0_.id as id0_0_, employee0_.name as name0_0_ from employee employee0_ where employee0_.id=? Hibernate: select skills0_.employee_id as employee1_1_, skills0_.skill_id as skill2_1_, skill1_.id as id1_0_, skill1_.name as name1_0_ from employee_skills skills0_ left outer join skill skill1_ on skills0_.skill_id=skill1_.id where skills0_.employee_id=? In that I specifically want to avoid the second query as the first one is unavoidable anyway.

• How best to modernize the 2002-era J2EE app?

  - by user331465

  I have this friend.... I have this friend who works on a java ee application (j2ee) application started in the early 2000's. Currently they add a feature here and there, but have a large codebase. Over the years the team has shrunk by 70%. [Yes, the "i have this friend is". It's me, attempting to humorously inject teenage high-school counselor shame into the mix] Java, Vintage 2002 The application uses EJB 2.1, struts 1.x, DAO's etc with straight jdbc calls (mixture of stored procedures and prepared statements). No ORM. For caching they use a mixture of OpenSymphony OSCache and a home-grown cache layer. Over the last few years, they have spent effort to modernize the UI using ajax techniques and libraries. This largely involves javascript libaries (jquery, yui, etc). Client Side On the client side, the lack of upgrade path from struts1 to struts2 discouraged them from migrating to struts2. Other web frameworks became popular (wicket, spring , jsf). Struts2 was not the "clear winner". Migrating all the existing UI from Struts1 to Struts2/wicket/etc did not seem to present much marginal benefit at a very high cost. They did not want to have a patchwork of technologies-du-jour (subsystem X in Struts2, subsystem Y in Wicket, etc.) so developer write new features using Struts 1. Server Side On the server side, they looked into moving to ejb 3, but never had a big impetus. The developers are all comfortable with ejb-jar.xml, EJBHome, EJBRemote, that "ejb 2.1 as is" represented the path of least resistance. One big complaint about the ejb environment: programmers still pretend "ejb server runs in separate jvm than servlet engine". No app server (jboss/weblogic) has ever enforced this separation. The team has never deployed the ejb server on a separate box then the app server. The ear file contains multiple copies of the same jar file; one for the 'web layer' (foo.war/WEB-INF/lib) and one for the server side (foo.ear/). The app server only loads one jar. The duplications makes for ambiguity. Caching As for caching, they use several cache implementations: OpenSymphony cache and a homegrown cache. Jgroups provides clustering support Now What? The question: The team currently has spare cycles to to invest in modernizing the application? Where would the smart investor spend them? The main criteria: 1) productivity gains. Specifically reducing the time to develope new subsystems features and reduced maintenance. 2) performance/scalability. They do not care about fashion or techno-du-jour street cred. What do you all recommend? On the persistence side Switch everything (or new development only) to JPA/JPA2? Straight hibernate? Wait for Java EE 6? On the client/web-framework side: Migrate (some or all) to struts2? wicket? jsf/jsf2? As for caching: terracotta? ehcache? coherence? stick with what they have? how best to take advantage of the huge heap sizes that the 64-bit jvms offer? Thanks in advance.

• Java error starting with "log4j:WARN No appenders could be found for logger" in ZuckerReports SugarC

  - by Tom McDonnell

  Greetings all. I apologise for posting this problem here, but I do so in desperation after receiving no response on the SugarCRM forums. Even if a reader is unfamiliar with ZuckerReports or SugarCRM some general advice on Java may be of use to me. I have installed ZuckerReports v1.12 in SugarCRM 5.5.1. When I attempt to run a report I get the following error message. cmdline: javaw -classpath

The installation in which the report runs correctly is of the same version, and has the same version of the ZuckerReports module. The report previously ran correctly on both installations. I think that the only changes that have been made on the installation in which the report now does not work since the report was last successfully run are the additions of a few custom fields in the Contacts module. These changes should have nothing to do with ZuckerReports. I have tried uninstalling and reinstalling the ZuckerReports module, but the problem remains. A google search for the warnings given in the error message ie. * log4j:WARN No appenders could be found for logger (net.sf.jasperreports.extensions.ExtensionsEnviron ment). * log4j:WARN Please initialize the log4j system properly. Returns a few links (not specific to ZuckerReports) with tips similar to the following: * log4j.properties or log4j.xml needs to be on the classpath where log4j can find it. I cannot find a file with either of those names anywhere on my server, and yet the report can be run successfully on one of my SugarCRM installations. So I figure log4j must be being configured another way. Can anyone suggest a way to solve this problem? Or explain how I might discover how log4j is configured in ZuckerReports? Or explain how I might compare the working with the non-working installation in order to help find a solution? (I have tried searching for files containing "log4j" in both installations and comparing but all I can find are .jar files (nothing I can read with a text editor), and the .jar files found in each installation appear to be the same.)

  Hi, I am using hibernate search for my application. It is well configured and running perfectly till some time back, when it stopped working suddenly. The reason according to me being the number of my model (bean) classes. I have some 90 classes, which I add to my configuration, while building my Hibernate Configuration. When, I disable hibernate search (remove the search annotations and use Configuration instead of AnnotationsConfiguration), I try to start my application, it Works fine. But,the same app when I enable search, it just hangs up. I tried debugging and found the exact place where it hangs. After adding all the class to my AnnotationsConfiguration object, when I say cfg.buildSessionfactory(), It never comes out of that statement. (I have waited for hours!!!) Also when I decrease the number of my model classes (like say to half i.e. 50) it comes out of that statement and the application works fine.. Can Someone tell why is this happening?? My versions of hibernate are: hibernate-core-3.3.1.GA.jar hibernate-annotations-3.4.0.GA.jar hibernate-commons-annotations-3.1.0.GA.jar hibernate-search-3.1.0.GA.jar Also if need to avoid using AnnotationsConfiguration, I read that I need to configure the search event listeners explicitly.. can anyone list all the neccessary listeners and their respective classes? (I tried the standard ones given in Hibernate Search books, but they give me ClassNotFound exception and I have all the neccesarty libs in classpath) Here are the last few lines of hibernate trace I managed to pull : 16:09:32,814 INFO AnnotationConfiguration:369 -

• Where is the sample applications in the lastest Spring release(Spring Framework 3.0.2)?

  - by Yousui

  Hi guys, On the Spring download page, It says that For all Spring Framework releases, the basic release contains only the binaries while the -with-dependencies release contains everything the basic release contains plus all third-party dependencies, buildable source trees, and sample applications. When I download the spring-framework-3.0.2.RELEASE-dependencies.zip, after extract it I get a list of folders: I:\soft\java\spring-framework-3.0.2.RELEASE-dependencies\com.bea.commonj

I know one of the sample applications is called jpetstore in spring 2.0. I did search in these folders and can't find anything useful. By the way, I also download the basic release which is spring-framework-3.0.2.RELEASE.zip. In the readme.txt of the basic release I found the following text: GETTING STARTED Please consult the blog examples at http://blog.springsource.com as well as the sections of interest in the reference documentation. Sample applications and related material will be provided as separate downloads. But I still don't know where to download the sample applications. Anyone can help? Thanks in advance.
