• javax.naming.NameNotFoundException: Name [comp/env] is not bound in this Context. Unable to find [comp] error with java scheduler

  - by Morgan Azhari

  What I'm trying to do is to update my database after a period of time. So I'm using java scheduler and connection pooling. I don't know why but my code only working once. It will print: init success success javax.naming.NameNotFoundException: Name [comp/env] is not bound in this Context. Unable to find [comp]. at org.apache.naming.NamingContext.lookup(NamingContext.java:820) at org.apache.naming.NamingContext.lookup(NamingContext.java:168) at org.apache.naming.SelectorContext.lookup(SelectorContext.java:158) at javax.naming.InitialContext.lookup(InitialContext.java:411) at test.Pool.main(Pool.java:25) ---> line 25 is Context envContext = (Context)initialContext.lookup("java:/comp/env"); I don't know why it only works once. I already test it if I didn't running it without java scheduler and it works fine. No error whatsoerver. Don't know why i get this error if I running it using scheduler. Hope someone can help me. My connection pooling code: public class Pool { public DataSource main() { try { InitialContext initialContext = new InitialContext(); Context envContext = (Context)initialContext.lookup("java:/comp/env"); DataSource datasource = new DataSource(); datasource = (DataSource)envContext.lookup("jdbc/test"); return datasource; } catch (Exception ex) { ex.printStackTrace(); } return null; } } my web.xml: <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <listener> <listener-class> package.test.Pool</listener-class> </listener> <resource-ref> <description>DB Connection Pooling</description> <res-ref-name>jdbc/test</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> Context.xml: <?xml version="1.0" encoding="UTF-8"?> <Context path="/project" reloadable="true"> <Resource auth="Container" defaultReadOnly="false" driverClassName="com.mysql.jdbc.Driver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" initialSize="0" jdbcInterceptors="org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer" jmxEnabled="true" logAbandoned="true" maxActive="300" maxIdle="50" maxWait="10000" minEvictableIdleTimeMillis="300000" minIdle="30" name="jdbc/test" password="test" removeAbandoned="true" removeAbandonedTimeout="60" testOnBorrow="true" testOnReturn="false" testWhileIdle="true" timeBetweenEvictionRunsMillis="30000" type="javax.sql.DataSource" url="jdbc:mysql://localhost:3306/database?noAccessToProcedureBodies=true" username="root" validationInterval="30000" validationQuery="SELECT 1"/> </Context> my java scheduler public class Scheduler extends HttpServlet{ public void init() throws ServletException { System.out.println("init success"); try{ Scheduling_test test = new Scheduling_test(); ScheduledExecutorService executor = Executors.newScheduledThreadPool(100); ScheduledFuture future = executor.scheduleWithFixedDelay(test, 1, 60 ,TimeUnit.SECONDS); }catch(Exception e){ e.printStackTrace(); } } } Schedule_test public class Scheduling_test extends Thread implements Runnable{ public void run(){ Updating updating = new Updating(); updating.run(); } } updating public class Updating{ public void run(){ ResultSet rs = null; PreparedStatement p = null; StringBuilder sb = new StringBuilder(); Pool pool = new Pool(); Connection con = null; DataSource datasource = null; try{ datasource = pool.main(); con=datasource.getConnection(); sb.append("SELECT * FROM database"); p = con.prepareStatement(sb.toString()); rs = p.executeQuery(); rs.close(); con.close(); p.close(); datasource.close(); System.out.println("success"); }catch (Exception e){ e.printStackTrace(); } }

• Wicket, Spring and Hibernate - Testing with Unitils - Error: Table not found in statement [select re

  - by John

  Hi there. I've been following a tutorial and a sample application, namely 5 Days of Wicket - Writing the tests: http://www.mysticcoders.com/blog/2009/03/10/5-days-of-wicket-writing-the-tests/ I've set up my own little project with a simple shoutbox that saves messages to a database. I then wanted to set up a couple of tests that would make sure that if a message is stored in the database, the retrieved object would contain the exact same data. Upon running mvn test all my tests fail. The exception has been pasted in the first code box underneath. I've noticed that even though my unitils.properties says to use the 'hdqldb'-dialect, this message is still output in the console window when starting the tests: INFO - Dialect - Using dialect: org.hibernate.dialect.PostgreSQLDialect. I've added the entire dump from the console as well at the bottom of this post (which goes on for miles and miles :-)). Upon running mvn test all my tests fail, and the exception is: Caused by: java.sql.SQLException: Table not found in statement [select relname from pg_class] at org.hsqldb.jdbc.Util.sqlException(Unknown Source) at org.hsqldb.jdbc.jdbcStatement.fetchResult(Unknown Source) at org.hsqldb.jdbc.jdbcStatement.executeQuery(Unknown Source) at org.apache.commons.dbcp.DelegatingStatement.executeQuery(DelegatingStatement.java:188) at org.hibernate.tool.hbm2ddl.DatabaseMetadata.initSequences(DatabaseMetadata.java:151) at org.hibernate.tool.hbm2ddl.DatabaseMetadata.(DatabaseMetadata.java:69) at org.hibernate.tool.hbm2ddl.DatabaseMetadata.(DatabaseMetadata.java:62) at org.springframework.orm.hibernate3.LocalSessionFactoryBean$3.doInHibernate(LocalSessionFactoryBean.java:958) at org.springframework.orm.hibernate3.HibernateTemplate.doExecute(HibernateTemplate.java:419) ... 49 more I've set up my unitils.properties file like so: database.driverClassName=org.hsqldb.jdbcDriver database.url=jdbc:hsqldb:mem:PUBLIC database.userName=sa database.password= database.dialect=hsqldb database.schemaNames=PUBLIC My abstract IntegrationTest class: @SpringApplicationContext({"/com/upbeat/shoutbox/spring/applicationContext.xml", "applicationContext-test.xml"}) public abstract class AbstractIntegrationTest extends UnitilsJUnit4 { private ApplicationContext applicationContext; } applicationContext-test.xml: <?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:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd" <bean id="dataSource" class="org.unitils.database.UnitilsDataSourceFactoryBean"/ </beans and finally, one of the test classes: package com.upbeat.shoutbox.web; import org.apache.wicket.spring.injection.annot.test.AnnotApplicationContextMock; import org.apache.wicket.util.tester.WicketTester; import org.junit.Before; import org.junit.Test; import org.unitils.spring.annotation.SpringBeanByType; import com.upbeat.shoutbox.HomePage; import com.upbeat.shoutbox.integrations.AbstractIntegrationTest; import com.upbeat.shoutbox.persistence.ShoutItemDao; import com.upbeat.shoutbox.services.ShoutService; public class TestHomePage extends AbstractIntegrationTest { @SpringBeanByType private ShoutService svc; @SpringBeanByType private ShoutItemDao dao; protected WicketTester tester; @Before public void setUp() { AnnotApplicationContextMock appctx = new AnnotApplicationContextMock(); appctx.putBean("shoutItemDao", dao); appctx.putBean("shoutService", svc); tester = new WicketTester(); } @Test public void testRenderMyPage() { //start and render the test page tester.startPage(HomePage.class); //assert rendered page class tester.assertRenderedPage(HomePage.class); //assert rendered label component tester.assertLabel("message", "If you see this message wicket is properly configured and running"); } } Dump from console when running mvn test: [INFO] Scanning for projects...

• Part 1 - 12c Database and WLS - Overview

  - by Steve Felts

  The download of Oracle 12c database became available on June 25, 2013.  There are some big new features in 12c database and WebLogic Server will take advantage of them. Immediately, we will support using 12c database and drivers with WLS 10.3.6 and 12.1.1.  When the next version of WLS ships, additional functionality will be supported (those rows in the table below with all "No" values will get a "Yes).  The following table maps the Oracle 12c Database features supported with various combinations of currently available WLS releases, 11g and 12c Drivers, and 11g and 12c Databases. Feature WebLogic Server 10.3.6/12.1.1 with 11g drivers and 11gR2 DB WebLogic Server 10.3.6/12.1.1 with 11g drivers and 12c DB WebLogic Server 10.3.6/12.1.1 with 12c drivers and 11gR2 DB WebLogic Server 10.3.6/12.1.1 with 12c drivers and 12c DB JDBC replay No No No Yes (Active GridLink only in 10.3.6, add generic in 12.1.1) Multi Tenant Database No Yes (except set container) No Yes (except set container) Dynamic switching between Tenants No No No No Database Resident Connection pooling (DRCP) No No No No Oracle Notification Service (ONS) auto configuration No No No No Global Database Services (GDS) No Yes (Active GridLink only) No Yes (Active GridLink only) JDBC 4.1 (using ojdbc7.jar files & JDK 7) No No Yes Yes  The My Oracle Support (MOS) document covering this is "WebLogic Server 12.1.1 and 10.3.6 Support for Oracle 12c Database [ID 1564509.1]" at the link https://support.oracle.com/epmos/faces/DocumentDisplay?id=1564509.1. The following documents are also key references:12c Oracle Database Developer Guide http://docs.oracle.com/cd/E16655_01/appdev.121/e17620/toc.htm 12c Oracle Database Administrator's Guide http://docs.oracle.com/cd/E16655_01/server.121/e17636/toc.htm . I plan to write some related blog articles not to duplicate existing product documentation but to introduce the features, provide some examples, and tie together some information to make it easier to understand. How do you get started with 12c?  The easiest way is to point your data source at a 12c database.  The only change on the WLS side is to update the URL in your data source (assuming that you are not just upgrading your database).  You can continue to use the 11.2.0.3 driver jar files that shipped with WLS 10.3.6 or 12.1.1.  You shouldn't see any changes in your application.  You can take advantage of enhancements on the database side that don't affect the mid-tier.  On the WLS side, you can take advantage of using Global Data Service or connecting to a tenant in a multi-tenant database transparently. If you want to use the 12c client jar files, it's a bit of work because they aren't shipped with WLS and you can't just drop in ojdbc6.jar as in the old days.  You need to use a matched set of jar files and they need to come before existing jar files in the CLASSPATH.  The MOS article is written from the standpoint that you need to get the jar files directly - download almost 1G and install over 600M footprint to get 15 jar files.  Assuming that you have the database installed and you can get access to the installation (or ask the DBA), you need to copy the 15 jar files to each machine with a WLS installation and get them in your CLASSPATH.  You can play with setting the PRE_CLASSPATH but the more practical approach may be to just update WL_HOME/common/bin/commEnv.sh directly.  There's a change in the transaction completion behavior (read the MOS) so if you think you might run into that, you will want to set -Doracle.jdbc.autoCommitSpecCompliant=false.  Also if you are running with Active GridLink, you must set -Doracle.ucp.PreWLS1212Compatible=true (how's that for telling you that this is fixed in WLS 12.1.2).  Once you get the configuration out of the way, you can start using the new ojdbc7.jar in place of the ojdbc6.jar to get the new JDBC 4.1 API's.  You can also start using Application Continuity.  This feature is also known as JDBC Replay because when a connection fails you get a new one with all JDBC operations up to the failure point automatically replayed.  As you might expect, there are some limitations but it's an interesting feature.  Obviously I'm going to focus on the 12c database features that we can leverage in WLS data source.  You will need to read other sources or the product documentation to get all of the new features.

• EPM 11.1.2.2 Architecture: Financial Performance Management Applications

  - by Marc Schumacher

   Financial Management can be accessed either by a browser based client or by SmartView. Starting from release 11.1.2.2, the Financial Management Windows client does not longer access the Financial Management Consolidation server. All tasks that require an on line connection (e.g. load and extract tasks) can only be done using the web interface. Any client connection initiated by a browser or SmartView is send to the Oracle HTTP server (OHS) first. Based on the path given (e.g. hfmadf, hfmofficeprovider) in the URL, OHS makes a decision to forward this request either to the new Financial Management web application based on the Oracle Application Development Framework (ADF) or to the .NET based application serving SmartView retrievals running on Internet Information Server (IIS). Any requests send to the ADF web interface that need to be processed by the Financial Management application server are send to the IIS using HTTP protocol and will be forwarded further using DCOM to the Financial Management application server. SmartView requests, which are processes by IIS in first row, are forwarded to the Financial Management application server using DCOM as well. The Financial Management Application Server uses OLE DB database connections via native database clients to talk to the Financial Management database schema. Communication between the Financial Management DME Listener, which handles requests from EPMA, and the Financial Management application server is based on DCOM.  Unlike most other components Essbase Analytics Link (EAL) does not have an end user interface. The only user interface is a plug-in for the Essbase Administration Services console, which is used for administration purposes only. End users interact with a Transparent or Replicated Partition that is created in Essbase and populated with data by EAL. The Analytics Link Server deployed on WebLogic communicates through HTTP protocol with the Analytics Link Financial Management Connector that is deployed in IIS on the Financial Management web server. Analytics Link Server interacts with the Data Synchronisation server using the EAL API. The Data Synchronization server acts as a target of a Transparent or Replicated Partition in Essbase and uses a native database client to connect to the Financial Management database. Analytics Link Server uses JDBC to connect to relational repository databases and Essbase JAPI to connect to Essbase.  As most Oracle EPM System products, browser based clients and SmartView can be used to access Planning. The Java based Planning web application is deployed on WebLogic, which is configured behind an Oracle HTTP Server (OHS). Communication between Planning and the Planning RMI Registry Service is done using Java Remote Message Invocation (RMI). Planning uses JDBC to access relational repository databases and talks to Essbase using the CAPI. Be aware of the fact that beside the Planning System database a dedicated database schema is needed for each application that is set up within Planning.  As Planning, Profitability and Cost Management (HPCM) has a pretty simple architecture. Beside the browser based clients and SmartView, a web service consumer can be used as a client too. All clients access the Java based web application deployed on WebLogic through Oracle HHTP Server (OHS). Communication between Profitability and Cost Management and EPMA Web Server is done using HTTP protocol. JDBC is used to access the relational repository databases as well as data sources. Essbase JAPI is utilized to talk to Essbase.  For Strategic Finance, two clients exist, SmartView and a Windows client. While SmartView communicates through the web layer to the Strategic Finance Server, Strategic Finance Windows client makes a direct connection to the Strategic Finance Server using RPC calls. Connections from Strategic Finance Web as well as from Strategic Finance Web Services to the Strategic Finance Server are made using RPC calls too. The Strategic Finance Server uses its own file based data store. JDBC is used to connect to the EPM System Registry from web and application layer.  Disclosure Management has three kinds of clients. While the browser based client and SmartView interact with the Disclosure Management web application directly through Oracle HTTP Server (OHS), Taxonomy Designer does not connect to the Disclosure Management server. Communication to relational repository databases is done via JDBC, to connect to Essbase the Essbase JAPI is utilized.

• Deploying Oracle ADF Essentials Applications to Glassfish

  - by Shay Shmeltzer

  With the new Oracle ADF Essentials offering you can now deploy applications that leverage Oracle ADF on the open source Glassfish 3.1 server. Deployment is documented in the official JDeveloper and ADF documentation (here) but below is a summary of the steps and a video of the steps you'll need to take to get a basic Oracle ADF Essentials application to work on GlassFish. Note - to make starting/stopping GlassFish easier for my demo I used my GlassFish extension that you can get here. First we'll install some ADF Runtime libraries on GlassFish Download and install Glassfish (Note - if you also have an Oracle DB on the same machine, you'll want to switch GlassFish's HTTP port to something else instead of 8080). Download the Oracle ADF Essentials packaging - this will get you an adf_essentials.zip file. Copy the adf_essentials.zip to the lib directory of your Glassfish domain - on a default windows install this would be: C:\glassfish3\glassfish\domains\domain1\lib Go the the above lib directory and issue a unzip -j adf_essentials.zip This will extract the ADF libraries to the directory. Now you can start the Glassfish server. Now let's configure Glassfish to handle applications of the ADF type: Invoke the admin console of glassfish (http://localhost:4848) and log into your admin account. Go to Configurations->Server-config->JVM Settings and choose the JVM Options tab Add the following entries: -XX:MaxPermSize=512m (note this entry should already exist so just make sure it has a big enough value) -Doracle.mds.cache=simple While we are in the admin console, we can also define JDBC connections that will be used by our application. Go into Resources->JDBC->JDBC Connection Pools and click to create a New one Give it a name and choose the resource type to be javax.sql.XADataSource and choose Oracle as the Database Driver vendor. Click Next Scroll down to the Additional Properties section and start filling in the information for your database. The values for an Oracle XE will be (user=hr, databaseName = XE, Password=hr, ServerName=localhost, DriverType=thin, PortNumber=1521) Click Finish Click Ping to check your connection works. Now define a new JDBC Resource that will use the pool you just defined. In my example I called the resource jdbc/HRDS You will need this name to match the name in your Application Module connection configuraiton.Now you can re-start the Glassfish server for the changes to take effect. Get an ADF application going (you can use the regular Fusion Application template for this) Go into the project properties of your viewController project, under the deployment section click to edit the deployment profile that is defined there. Go to Platform and choose Glassfish 3.1 from the drop down list. Click ok to go back to your project. Go to Application -> Application Properties-> Deployment Go to Platform and choose Glassfish 3.1 from the drop down list. Click ok to go back to your project. This step will make sure that JDeveloper will autoamtically add the necessary ADF libraries to the EAR file that is being generated for deployment on Glassfish  Go to your Application->Deploy and deploy either to an EAR file or directly to a Glassfish server connection that you created. Things should just work, but if they don't then look up the server.log in the log directory and check out what error is in there. Here is a video demo of the various steps: Note - right now the deployment of an ADF application takes about 2 minutes on my machine we are hoping to be able to improve this timing in the future. People who are more familiar with Glassfish might want to explore using exploded directory deployment and see if they can get it to work.

  Hi all, I am new to Pentaho, and I am struggling to set up a new database connection. I am trying to connect to an Oracle 10g database, but whenever I test the connection, I get the below error.

• quartz throws deadlocks under load

  - by Khandelwal

  We are using Quartz with Spring and our configuration is throwing deadlocks when quartz has more than 1 thread configured. I'm starting to believe that it's because we don't have our quartz configured correctly with Spring, but I can't find enough documentation on how to configure the two to play nicely. We are running on both Windows and Linux environments - pointing at MSSQL and Oracle DBs. With both OS, using either DB, we can throw the following deadlock errors... We're consistently throwing these deadlock errors. We run under heavy load, inserting hundreds of quartz triggers in a matter of minutes. 2010-03-17 18:52:31,737 [] [] ERROR [DFScheduler_Worker-42] core.ErrorLogger core.ErrorLogger (QuartzScheduler.java:2185) - An error occured while marking executed job complete. job= 'BPM.6e41a6567f0000020100362a51dc7a50' org.quartz.JobPersistenceException: Couldn't remove trigger: Transaction (Process ID 87) was deadlocked on lock resources with another process and has been chosen as the deadlock victim.

• Interoperability between Weblogic 10.3.1 and Oracle BPM 10.3.1

  - by alfredozn

  Hi, Im migrating an ALBPM 6.5 running on a WLS 10.0 to an Oracle BPM 10.3.1 running on WLS 10.3.1 I got some problems with the Oracle driver because the old driver (weblogic.jdbcx.oracle.OracleDataSource) was definitely removed from the server and is not longer supported. Instead I used the thin driver (oracle.jdbc.xa.OracleXADataSource), the database migration was executed succesfully but after that, when I try to deploy the engine ear in WebLogic I got exceptions asociated to the driver: [ (cont) ] Main: Caused by: weblogic.application.ModuleException: [HTTP:101216]Servlet: "engineStartup" failed to preload on startup in Web application: "/albpmServices/albpm_engine". [ (cont) ] Main: fuego.directory.DirectoryRuntimeException: Exception [java.sql.SQLException: Invalid column type]. [ (cont) ] Main: at fuego.directory.DirectoryRuntimeException.wrapException(DirectoryRuntimeException.java:85) [ (cont) ] Main: at fuego.directory.provider.jdbc.oracle.OraclePersistenceManager.mapSQLException(OraclePersistenceManager.java:145) [ (cont) ] Main: at fuego.directory.provider.jdbc.datadirect.oracle.DataDirectOraclePersistenceManager.mapSQLException(DataDirectOraclePersistenceManager.java:51) [ (cont) ] Main: at fuego.directory.provider.jdbc.JDBCServiceAccessor.mapSQLException(JDBCServiceAccessor.java:78) [ (cont) ] Main: at fuego.directory.provider.jdbc.JDBCObjectPropertiesAccessor.fetchAllDirectoryProperties(JDBCObjectPropertiesAccessor.java:442) [ (cont) ] Main: at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) I was looking around for a solution but all is pointing to use the old driver, I think isn't a good practice to force the server to use this driver after Oracle remove it completely. Any suggestions or similar experiences??

• EJB client can't find a DataSource that tests successfully in WebLogic admin console

  - by suszterpatt

  Disclaimer: I'm completely new to JEE/EJB and all that, so bear with me. I have a simple EJB that I can successfully deploy using JDeveloper 11g's integrated WebLogic server and a remote database connection (JDBC). I have a DataSource named "PGY2" defined in WebLogic, and I can test it successfully from the admin console. Here's the code of the client I'm trying to test it with (generated entirely by JDev except for the three method calls on adminManager): public class AdminManagerClient { public static void main(String [] args) { try { final Context context = getInitialContext(); AdminManager adminManager = (AdminManager)context.lookup("Uran-AdminManager#hu.elte.pgy2.BACNAAI.UranEJB.AdminManager"); adminManager.addAdmin("root", "root", "Kovács Isten"); adminManager.addStudent("BACNAAI", "matt", "B Cs", 2005); adminManager.addTeacher("SIPKABT", "patt", "S P", "numanal", "Dr."); } catch (Exception ex) { ex.printStackTrace(); } } private static Context getInitialContext() throws NamingException { Hashtable env = new Hashtable(); // WebLogic Server 10.x connection details env.put( Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory" ); env.put(Context.PROVIDER_URL, "t3://127.0.0.1:7101"); return new InitialContext( env ); } } But when I try to run this, I get the following error on the line with adminManager.addAdmin (that is, after the lookup): javax.ejb.EJBException: EJB Exception: ; nested exception is: Exception [EclipseLink-4002] (Eclipse Persistence Services - 1.0.2 (Build 20081024)): org.eclipse.persistence.exceptions.DatabaseException Internal Exception: java.sql.SQLException: Internal error: Cannot obtain XAConnection Creation of XAConnection for pool PGY2 failed after waitSecs:30 : java.sql.SQLException: Data Source PGY2 does not exist. Why can't the client find the data source, and how do I make it find it? EDIT: I took a closer look at WebLogic's output during deployment, and I found this. I have no idea what it means, but it may be relevant: <2010.05.20. 0:50:43 CEST> <Error> <Deployer> <BEA-149231> <Unable to set the activation state to true for the application 'PGY2'. weblogic.application.ModuleException: at weblogic.jdbc.module.JDBCModule.activate(JDBCModule.java:349) at weblogic.application.internal.flow.ModuleListenerInvoker.activate(ModuleListenerInvoker.java:107) at weblogic.application.internal.flow.DeploymentCallbackFlow$2.next(DeploymentCallbackFlow.java:411) at weblogic.application.utils.StateMachineDriver.nextState(StateMachineDriver.java:37) at weblogic.application.internal.flow.DeploymentCallbackFlow.activate(DeploymentCallbackFlow.java:74) Truncated. see log file for complete stacktrace weblogic.common.ResourceException: is already bound at weblogic.jdbc.common.internal.RmiDataSource.start(RmiDataSource.java:387) at weblogic.jdbc.common.internal.DataSourceManager.createAndStartDataSource(DataSourceManager.java:136) at weblogic.jdbc.common.internal.DataSourceManager.createAndStartDataSource(DataSourceManager.java:97) at weblogic.jdbc.module.JDBCModule.activate(JDBCModule.java:346) at weblogic.application.internal.flow.ModuleListenerInvoker.activate(ModuleListenerInvoker.java:107) Truncated. see log file for complete stacktrace >

• java.sql.SQLException: Parameter number X is not an OUT parameter

  - by Frederik

  Hi guys, I'm struggling with getting the result OUT variable from a MySQL stored procedure. I get the following error: java.sql.SQLException: Parameter number 3 is not an OUT parameter The stored procedure looks like this: CREATE DEFINER=`cv_admin`@`localhost` PROCEDURE `CheckGameEligibility`( IN gID INT(10), IN uID INT(10), OUT result TINYINT(1) ) BEGIN # Do lots of stuff, then eventually: SET result = 1; END My java function takes an array of strings* and creates the CallableStatement object dynamically: public static int callAndReturnResult( String sql , String[] values ) { int out = 0 ; try { // construct the SQL.

  Hi all, I am trying to create a Database Manager page which shows the database details on page load and updates the database settings when the user press submit I followed this tutorial and set the database settings in properties file. I managed to update the database settings in properties file programmatically. When I retrieved the database settings using the following code DriverManagerDataSource databaseSource = (DriverManagerDataSource)context.getBean("dataSource"); databaseSource.getUsername(); I managed to get the old value and unable to get the new value This is the mapping in applicationContext.xml file <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location"> <value>classpath:/bundle/database.properties</value> </property> </bean> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${jdbc.driverClassName}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> </bean> I checked the properties file and found it to be updated with the latest input.

• How do you unpack gems using jruby on rails 2.3?

  - by James Moore

  I'm trying to unpack all the system gems to end up with a standalone Rails directory including all the rails gems and all the system gems. I'm starting with a bare rails setup; just did a jruby -S rails and a 'generate jdbc'. I then add a config.gem 'jdbc-mysql' to environment.rb and do the jruby -S rake gems:unpack:dependencies. After unpacking, if I do a rake I get: no such file to load -- jdbc-mysql Is there something else you need to do to get the jdbc gem unpacked?

• Hibernate saveorUpdate method problem

  - by umesh awasthi

  Hi all, i am trying to work on with Hibernate (Database side for first time) and some how struck in choosing best possible way to use saveOrUpdate or Save.Update i have a destination POJO class and its other attributes which needs to be updated along with the Destination entity. i am getting an XML file to be imported and i am using the following code to update/save the destination entity along with its attribute classes. try{ getSessionFactory().getCurrentSession().beginTransaction(); getSessionFactory().getCurrentSession().saveOrUpdate(entity); getSessionFactory().getCurrentSession().getTransaction().commit(); } catch(Exception e){ getSessionFactory().getCurrentSession().getTransaction().rollback(); } finally{ getSessionFactory().close(); } everything is working fine untill i am using the same session instance.but later on when i am using the same XML file to update the destination PO for certain attributes it giving me the following error. SEVERE: Duplicate entry 'MNLI' for key 'DESTINATIONID' 9 Jan, 2011 4:58:11 PM org.hibernate.event.def.AbstractFlushingEventListener performExecutions SEVERE: Could not synchronize database state with session org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:94) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66) at org.hibernate.jdbc.AbstractBatcher.executeBatch(AbstractBatcher.java:275) at org.hibernate.jdbc.AbstractBatcher.prepareStatement(AbstractBatcher.java:114) at org.hibernate.jdbc.AbstractBatcher.prepareStatement(AbstractBatcher.java:109) at org.hibernate.jdbc.AbstractBatcher.prepareBatchStatement(AbstractBatcher.java:244) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2242) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2678) at org.hibernate.action.EntityInsertAction.execute(EntityInsertAction.java:79) i am using UUID as primary key for the Destination table and in destination table i have a destination id which is unique.but i can understand that in the secodn case hibernate is not able to find if there is already an entry for the same destination in the DB and trying to execute insert statement rather than update. one possible solution is i can user destinationid to check if there is already a destination inplace with the given id and based on the results i can issue save or update command. my question is can this be achieve by any other good way..? Thanks in advance

• 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.

I created a stored procedure in a sql express 2008 and I'm getting the following error when calling the procedure from a Java method: Index 36 is out of range. com.microsoft.sqlserver.jdbc.SQLServerException:Index 36 is out of range. at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDriverError(SQLServerException.java:170) at com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement.setterGetParam(SQLServerPreparedStatement.java:698) at com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement.setValue(SQLServerPreparedStatement.java:707) at com.microsoft.sqlserver.jdbc.SQLServerCallableStatement.setString(SQLServerCallableStatement.java:1504) at fr.alti.ccm.middleware.Reporting.initReporting(Reporting.java:227) at fr.alti.ccm.middleware.Reporting.main(Reporting.java:396) I cannot figure out where it is coming from... _< Any help would be appreciated. Regards, BS_C3 Here's some source code: public ArrayList<ReportingTableMapping> initReporting( String division, String shop, String startDate, String endDate) { ArrayList<ReportingTableMapping> rTable = new ArrayList<ReportingTableMapping>(); ManagerDB db = new ManagerDB(); CallableStatement callStmt = null; ResultSet rs = null; try { callStmt = db.getConnexion().prepareCall("{call getInfoReporting(?,...,?)}"); callStmt.setString("CODE_DIVISION", division); . . . callStmt.setString("cancelled", " "); rs = callStmt.executeQuery(); while (rs.next()) { ReportingTableMapping rtm = new ReportingTableMapping( rs.getString("werks"), ... ); rTable.add(rtm); } rs.close(); callStmt.close(); } catch (Exception e) { System.out.println(e.getMessage()); e.printStackTrace(); } finally { if (rs != null) try { rs.close(); } catch (Exception e) { } if (callStmt != null) try { callStmt.close(); } catch (Exception e) { } if (db.getConnexion() != null) try { db.getConnexion().close(); } catch (Exception e) { } } return rTable; }

• How to create an entity with a composite primary key containing a generated value.

  - by David

  Using Hibernate + annotations, I'm trying to do the following: Two entities, Entity1 and Entity2. Entity1 contains a simple generated value primary key. Entity2 primary key is composed by a simple generated value + the id of entity one (with a many to one relationship) Unfortunately, I can't make it work. Here is an excerpt of the code: @Entity public class Entity1 { @Id @GeneratedValue private Long id; private String name; ... } @Entity public class Entity2 { @EmbeddedId private Entity2PK pk = new Entity2PK(); private String miscData; ... } @Embeddable public class Entity2PK implements Serializable { @GeneratedValue private Long id; @ManyToOne private Entity1 entity; } void test() { Entity1 e1 = new Entity1(); e1.setName("nameE1"); Entity2 e2 = new Entity2(); e2.setEntity1(e1); e2.setMiscData("test"); Transaction transaction = session.getTransaction(); try { transaction.begin(); session.save(e1); session.save(e2); transaction.commit(); } catch (Exception e) { transaction.rollback(); } finally { session.close(); } } When I run the test method I get the following errors: Hibernate: insert into Entity1 (id, name) values (null, ?) Hibernate: call identity() Hibernate: insert into Entity2 (miscData, entity_id, id) values (?, ?, ?) 07-Jun-2010 10:51:11 org.hibernate.util.JDBCExceptionReporter logExceptions WARNING: SQL Error: 0, SQLState: null 07-Jun-2010 10:51:11 org.hibernate.util.JDBCExceptionReporter logExceptions SEVERE: failed batch 07-Jun-2010 10:51:11 org.hibernate.event.def.AbstractFlushingEventListener performExecutions SEVERE: Could not synchronize database state with session org.hibernate.exception.GenericJDBCException: Could not execute JDBC batch update at org.hibernate.exception.SQLStateConverter.handledNonSpecificException(SQLStateConverter.java:103) at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:91) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:43) at org.hibernate.jdbc.AbstractBatcher.executeBatch(AbstractBatcher.java:254) at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:266) at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:167) at org.hibernate.event.def.AbstractFlushingEventListener.performExecutions(AbstractFlushingEventListener.java:298) at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:27) at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1001) at org.hibernate.impl.SessionImpl.managedFlush(SessionImpl.java:339) at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:106) at test.App.main(App.java:32) Caused by: java.sql.BatchUpdateException: failed batch at org.hsqldb.jdbc.jdbcStatement.executeBatch(Unknown Source) at org.hsqldb.jdbc.jdbcPreparedStatement.executeBatch(Unknown Source) at org.hibernate.jdbc.BatchingBatcher.doExecuteBatch(BatchingBatcher.java:48) at org.hibernate.jdbc.AbstractBatcher.executeBatch(AbstractBatcher.java:247) ... 8 more Note that I use HSQLDB.

• Jython & Mysql - what is the current practice for connection?

  - by Sector7B

  Just trying jython for the first time, because something came up at work that would fit for this perfect for it. I assume jython can make mysql jdbc connection using the mysql jdbc driver. After googling and reading, however I am having problems and it seems jython specific and probably simple. so i do jython: Jython 2.5.1 (Release_2_5_1:6813, Sep 26 2009, 13:47:54) [Java HotSpot(TM) 64-Bit Server VM (Apple Inc.)] on java1.6.0_17 Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> print sys.path ['', '/JYTHONPATH/mysql-connector-java-5.1.10-bin.jar', '/WorkArea/Apps/jython/jython2.5.1/Lib', '__classpath__', '__pyclasspath__/', '/WorkArea/Apps/jython/jython2.5.1/Lib/site-packages'] >>> code i'm running from java.lang import * from java.sql import * driverName="com.mysql.jdbc.Driver" Class.forName(driverName) url = "jdbc:mysql://localhost/test?user=jgreenaw&password=" con = DriverManager.getConnection(url) stmt = con.createStatement() output riux:Desktop$ jython pymysql.py Traceback (most recent call last): File "pymysql.py", line 7, in <module> Class.forName(driverName) at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:315) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330) at java.lang.ClassLoader.loadClass(ClassLoader.java:250) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:398) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:169) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) java.lang.ClassNotFoundException: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver any advice? thanks
