[iReport will no load class (int)?!]

Why the wrapper classes aren't used automatically?

[iReport 3.5.2 not starting and no error in Vista]

I think it shouldn't be necessary, but I've to set manually a userdir in <iReport install folder>/etc/ireport.conf:

 

default_options="-J-Xms256m -J-Xmx512m -J-Dfile.encoding=UTF-8 -J-Dorg.netbeans.ProxyClassLoader.level=1000 --userdir D:/Users/Felipe/.iReport/3.5.2"

 

If it's mandatory should be documented, don't you think?

[iReport will no load class (int)?!]

Hello,

I'm doing a report to test my new Hibernate connection and when I click Preview I get this, very strange, error:

net.sf.jasperreports.engine.design.JRValidationException: Report design not valid :       1. java.lang.ClassNotFoundException: Will not load classes from default package (int)      2. java.lang.ClassNotFoundException: Will not load classes from default package (boolean)      3. java.lang.ClassNotFoundException: Will not load classes from default package (boolean)      4. java.lang.ClassNotFoundException: Will not load classes from default package (boolean)

 

This errors refer to the following fields in mapping class:

1.     @Id
       @GeneratedValue(strategy = GenerationType.SEQUENCE,
           generator = "SequencePedidoVenda")
       @Min(0)
       private int id;
2.     @Transient
       private boolean itensWithErros;
3.     @Column(name="LANCADO_ESTOQUE")
       @Type(type="SimNaoChar")
       private boolean lancadoEstoque;
4.     @Column(name="LANCADO_ESTOQUE_PROGRAMADO")
       @Type(type="SimNaoChar")
       private boolean lancadoEstoqueProgramado;

Why iReport is complaing about java.lang classes?

[iReport 3.5.2 not starting and no error in Vista]

Hello,

 

I've just download iReport-nb-3.5.2-windows-installer.exe and installed it. When I click in Start Menu / Programs / iReport / iReport-nb-3.5.2 nothing happens, no error messages and no iReport at all.

I already set the jdkhome in ireport.conf, but didn't work either.

What can I do to see what's wrong?

I'm using Windows Vista SP1 and JDK6_13

[EJBQL connection not working and no error messages]

Hi mirianoe,

 

Solve this issue was very annoying.

 

I never use TopLink but the main problem I had was the jar in iReport's lib directory, put all the necessary jars of TopLink in lib and update the jpa.jar (Hibernate the most recent version is called ejb3-persistence.jar).

[EJBQL connection not working and no error messages]

I did set some specific hibernate configurations and now everything is working too. The details about hibernate configurations isn't for this forum.

 

Thanks all for help! :cheer:

[EJBQL connection not working and no error messages]

For me works as well. Using a test persistence.xml the connection was tested successfully.

 

But when I use the actual classes of my project things don't works as expected...

 

I've some UserType defined in package level. When runing my project inside the container hibernate uses auto detection to search the package-info.java and all the entity classes. But, inside iReport auto detection doesn't work, then I specified all the classes with <class> but I get this error:

 

Caused by: org.hibernate.MappingException: Could not etermine type for: SimNaoChar, at table: LOCALCOB, for columns: [org.hibernate.mapping.Column(MOSTRAR_SITE)]

 

Means hibernate can't find the package-info.java and I can't find a way to "force" him.

 

junejava, can you test if in production environment(only JasperReports) the report, using EJBQL connection, go ok?

[EJBQL connection not working and no error messages]

I update this files in iReport/lib, removing the old versions:

 

antlr-2.7.6.jar

commons-collections-2.1.1.jar

commons-logging-1.0.4.jar

dom4j-1.6.1.jar

ehcache-1.2.3

jta.jar

log4j-1.2.11.jar

xml-apis.jar

 

Remove these files from Classpath and put them in iReport/lib:

 

hibernate-annotations.jar

hibernate-commons-annotations.jar

hibernate-entitymanager.jar

hibernate-validator.jar

jboss-archive-browsing.jar

 

javassist.jar (after an error NoClassDefFound for javaassist)

 

Now when I test the connection I get an error telling me that the class or package of my project wasn't found. This is good, hibernate is running and not find classes that are in persistence.xml

 

I'm still trying and will post here when I get news.

[EJBQL connection not working and no error messages]

I update the hibernate3.jar, asm.jar, asm-attr.jar and cglib-2.1.3.jar and like junejava change jpa.jar to ejb3-persistence.jar.

 

I don't add files in lib that don't was there. I put this files in classpath:

 

D:/Java/Jaybird-2.1.1JDK_1.5/jaybird-full-2.1.1.jar

D:/Java/iReport classpath

D:/Java/hibernate-entitymanager-3.3.1.GA/lib/hibernate-annotations.jar

D:/Java/hibernate-entitymanager-3.3.1.GA/lib/hibernate-commons-annotations.jar

D:/Java/hibernate-entitymanager-3.3.1.GA/hibernate-entitymanager.jar

D:/Java/hibernate-entitymanager-3.3.1.GA/lib/hibernate-validator.jar

D:/Java/hibernate-entitymanager-3.3.1.GA/lib/jboss-archive-browsing.jar

 

Restart the iReport and try to test an EJBQL Connection, now I get this error:

 

java.lang.IllegalAccessError: tried to access method org.hibernate.engine.CascadeStyle.<init>()V from class org.hibernate.engine.EJB3CascadeStyle$1 at org.hibernate.engine.EJB3CascadeStyle$1.<init>(EJB3CascadeStyle.java:24) at org.hibernate.engine.EJB3CascadeStyle.<clinit>(EJB3CascadeStyle.java:19) at org.hibernate.ejb.event.EJB3PersistEventListener.<clinit>(EJB3PersistEventListener.java:19) at org.hibernate.ejb.EventListenerConfigurator.<init>(EventListenerConfigurator.java:80) at org.hibernate.ejb.Ejb3Configuration.<init>(Ejb3Configuration.java:132) at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:119) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:51) at it.businesslogic.ireport.connection.EJBQLConnection.getEntityManager(EJBQLConnection.java:130) at it.businesslogic.ireport.connection.EJBQLConnection$1.run(EJBQLConnection.java:178) at java.awt.event.InvocationEvent.dispatch(Unknown Source)

 

I don't know what is IllegalAccessError, so from Java Docs I get:

 

Thrown if an application attempts to access or modify a field, or to call a method that it does not have access to. Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed.

 

IMO we've to update more libraries..

 

Thanks for helping.

Hi giulio,

 

I'll do a simple test case to you. But I can't do now.

 

What's the limit to submit a file here?

 

Thanks

[Will you update the hibernate support?]

The version of hibernate bundled with iReport 2.0.4 is the 3.0.5. But to support annotations and JPA (Hibernate Entity Manager) is necessary version 3.2.x.

 

Is there plans to update the supported version?

[EJBQL connection not working and no error messages]

The version of hibernate bundled with iReport 2.0.4 is completely out of date, the version is 3.0.5.

 

To support annotations and JPA (EntityManager) hibernate must be 3.2.x.

 

So, there's plans to update the support? If not at least a workaround to use the new version.

[EJBQL connection not working and no error messages]

So, I'm still trying. Nobody is helping (hibernate forum and here) but...

 

The hibernate3.jar in iReport/lib is out of date. I replace the file with my hibernate3.jar and now the missing method was found but the error changed to:

 

java.lang.NoClassDefFoundError: org/hibernate/bytecode/cglib/BytecodeProviderImpl at org.hibernate.cfg.Environment.buildBytecodeProvider(Environment.java:690) at org.hibernate.cfg.Environment.buildBytecodeProvider(Environment.java:682) at org.hibernate.cfg.Environment.<clinit>(Environment.java:568) at org.hibernate.cfg.Configuration.reset(Configuration.java:174) at org.hibernate.cfg.AnnotationConfiguration.reset(AnnotationConfiguration.java:220) at org.hibernate.cfg.Configuration.<init>(Configuration.java:193) at org.hibernate.cfg.Configuration.<init>(Configuration.java:197) at org.hibernate.cfg.AnnotationConfiguration.<init>(AnnotationConfiguration.java:96) at org.hibernate.ejb.Ejb3Configuration.<clinit>(Ejb3Configuration.java:105) at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:119) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:83) at com.jaspersoft.ireport.designer.connection.EJBQLConnection.getEntityManager(EJBQLConnection.java:138) at com.jaspersoft.ireport.designer.connection.EJBQLConnection$1.run(EJBQLConnection.java:188) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:209)

[EJBQL connection not working and no error messages]

I can't find a way to see iReport log. So I install the iReport for Netbeans to see if in IDE Log I could found the exception and it works, no solution yet but at least error messages.

 

After I put the jars of hibernate entity manager in iReport Classpath and try to test an EJBQL connection I get this exception:

 

java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.ejb.Ejb3Configuration at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:119) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:83) at com.jaspersoft.ireport.designer.connection.EJBQLConnection.getEntityManager(EJBQLConnection.java:138) at com.jaspersoft.ireport.designer.connection.EJBQLConnection$1.run(EJBQLConnection.java:188) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:209)

 

 

So even with the jars in classpath iReport can't find the class. Then I go to iReport Fontpath and select all the jars (listed bellow), saved fontpath and restart. Without no changes in iReport Classpath just in iReport Fontpath the exception now is:

 

java.lang.NoSuchMethodError: org.hibernate.cfg.AnnotationConfiguration.setEntityNotFoundDelegate(Lorg/hibernate/proxy/EntityNotFoundDelegate;)V at org.hibernate.ejb.Ejb3Configuration.<init>(Ejb3Configuration.java:131) at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:119) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:83) at com.jaspersoft.ireport.designer.connection.EJBQLConnection.getEntityManager(EJBQLConnection.java:138) at com.jaspersoft.ireport.designer.connection.EJBQLConnection$1.run(EJBQLConnection.java:188) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:209)

 

 

I don't give up. I'm trying. If anyone has any ideas please post here.

 

 

My iReport Classpath:

[EJBQL_Connection]

I create a topic about EJBQL connection tro try solve once for all our problem, take a look: EJBQL connection not working and no error messages

[EJBQL connection not working and no error messages]

I've seem a few posts talking about EJBQL connections. None of them have answer. (IMO) This subject is complete ignored for (at-least) non-commercial users.

 

So, lets try solve this problem.

 

I create a directory called iReport classpath and inside put my META-INF/persistence.xml, configure the classpath of iReport to point to "iReport classpath", create one EJBQL connection and click on Test button and I get this error:

 

"No Persistence provider for EntityManager named VCModelPU"

 

So I figured out iReport can't find my provider which is Hibernate EntityManger. Then I put the jars of hibernate entity manager in iReport classpath:

 

hibernate-entitymanager-3.3.1.GAlibejb3-persistence.jar hibernate-entitymanager-3.3.1.GAlibhibernate-annotations.jar hibernate-entitymanager-3.3.1.GAlibhibernate-commons-annotations.jar hibernate-entitymanager-3.3.1.GAlibhibernate-validator.jar hibernate-entitymanager-3.3.1.GAlibjboss-archive-browsing.jar hibernate-entitymanager-3.3.1.GAhibernate-entitymanager.jar

 

After this I restart iReport and try to test again the EJBQL connection and don't get any messages, success nor error messages appears. Seems like the button is ignored.

 

I'm trying to see the iReport log, but I don't find this. Anyone knows how can I activate a detailed log? I need to see the exceptions.
