DeploymentException: Could not instantiate EJBObject

I get a DeploymentException trying to deploy the most simple bean imaginable.
Looks like the problem is with an internal WebLogic object <beanName>_EO. I ran ejbc and it generated the classes, but for some reason the jar won't deploy.
Here is the stack trace:
weblogic.ejb.common.DeploymentException: Could not instantiate EJBObject.; nested exception is: javax.naming.NameNotFoundException: 'com/iic/test/util/echo_EO'; remaining name 'com/iic/test/util/echo_EO' javax.naming.NameNotFoundException: 'com/iic/test/util/echo_EO'; remaining name 'com/iic/test/util/echo_EO' at weblogic.jndi.toolkit.BasicWLContext.resolveName(BasicWLContext.java:745) at weblogic.jndi.toolkit.BasicWLContext.resolveNameToStore(BasicWLContext.java:656) at weblogic.jndi.toolkit.BasicWLContext.resolveNameToParentStore(BasicWLContext.java:707) at weblogic.jndi.toolkit.BasicWLContext.rebind(BasicWLContext.java:229) at weblogic.jndi.toolkit.ReplicatedWLContext.rebind(ReplicatedWLContext.java:91) at weblogic.jndi.toolkit.BasicWLContext.rebind(BasicWLContext.java:580) at weblogic.ejb.internal.StatelessEJBHome.setup(StatelessEJBHome.java:127) at weblogic.ejb.internal.EJBHomeImpl.setup(EJBHomeImpl.java:600) at weblogic.ejb.internal.EJBDeploymentImpl.setupBeanHome(EJBDeploymentImpl.java:576) at weblogic.ejb.internal.EJBDeploymentImpl.deployBeans(EJBDeploymentImpl.java:384) at weblogic.ejb.internal.EJBDeploymentImpl.deploy(EJBDeploymentImpl.java:335) at weblogic.ejb.internal.EJBJarDeployment.deploy(EJBJarDeployment.java:231) at weblogic.ejb.internal.EJBManagerImpl.deploy(EJBManagerImpl.java:363) at weblogic.ejb.internal.EJBManagerImpl.deployNew(EJBManagerImpl.java:352) at weblogic.ejb.internal.EJBManagerImpl.deploy(EJBManagerImpl.java:319) at weblogic.ejb.internal.EJBManagerImpl.deployBeans(EJBManagerImpl.java:629) at weblogic.ejb.internal.EJBManagerImpl.<init>(EJBManagerImpl.java:242) at weblogic.t3.srvr.T3Srvr.start(T3Srvr.java:1295) at weblogic.t3.srvr.T3Srvr.main(T3Srvr.java:825) at java.lang.reflect.Method.invoke(Native Method) at weblogic.Server.startServerDynamically(Server.java:99) at weblogic.Server.main(Server.java:65) at weblogic.Server.main(Server.java:55)

Help me pls to resolve the problem: WebService client SOAP exception: SAXException: Could not instantiate bean ...

Hi all,
I use Weblogic 6.1 SOAP
If any body know what does this mean and how this may be resolved please
help me
I try to send JavaBean class "A" which includes an array of JavaBean class
"B" which includes an array of string objects
from server side to the client.
class A {
B[] aBeans
setABeans(B[] aBeans) {}
getABeans() {}
class B {
String[] props;
setProps(String[] props) {}
getProps() {}
And only half of the method invocation is ok - data is transmitted by soap
and is displayed
at the client side in "verbose=true" mode and i see that data is received
completely but the client side JavaBean class "A"
was not initialized because the exception was thrown when soap trying to
instantiate JavaBean class "B":
SAXException: Could not instantiate bean: B
I looked at jdk API and the InstantiationException is thrown only if class
is an interface or an abstract class,
but class "B" is not abstract or interface, it is simple JavaBean class.
What is the trouble?
Help me pls

Hi, Pieter!
Thanks in advance, this solve a problem.

Hi!
I think I know the problem.
Does your JavaBean has a default constructor (a parameterlessconstructor).

Try it!

is there anybody can tell me why i am getting this error? i was sitting in front of the computer for days now, but could find out where i am doing wrong.
i have tested my hibernate classes without session beans(in a normal java Project, every thing works fine. and i tried to do exactly what they have done in the HibernateExampleEHCache examples, to combine my hibernate with session beans together, but couldn't get the programm running. 

Are you sure this is the right value for the class name?
org.hibernate.transaction.SAPWebASTransactionManagerLookup
No, i am not sure. i just copied it from a example. but i think i will not need it. so i have deleted them now.
Looks as well like you have implemented a primary index scheme (next value) that is not supported by your DB ?
See error on DUAL
I just used sequence for the primary key in my Person.hbm.xml. even i change it to native, it comes back with the same error too.
Person.hbm.xml:
<class name="src.hibernate.Person" table="TMP_PERSON">
<id name="id" column="PERSONID">
<generator class="native"/>
java class:
public class Person {
 private Long id;
 getter and setter
my method in a stateless session bean:
public Long createPerson(
 String surname,
 String firstname,
 String tel,
 String email) {
 Session session = null;
 Transaction tx = null;
 try {
 session = HibernateSessionFactory.openSession();
 tx = session.beginTransaction();
 Person aPerson = new Person();
 aPerson.setSurname(surname);
 aPerson.setFirstname(firstname);
 aPerson.setTelNr(tel);
 aPerson.setEmail(email);
 Long personId = (Long)session.save(aPerson);
 tx.commit();
 return personId;
 } catch (HibernateException e) {
 if (tx != null)
 tx.rollback();
 throw new HibernateException(e);

LocalSessionFactoryBean - Could not instantiate bean class

Hello,
I am facing a problem with the instantiation of the LocaSessionFactoryBean in a sample Spring 3.0.4 - Hibernate 3.2.6, WebLogic 10.3.3 and Oracle 10g. I am run an web application using JDeveloper 11.1.1.3.0 with the integrated WebLogic Server 11gR1. Trying to make the existing web application that is currently running on Oracle Web Server to run on WebLogic.
I have gone through other LocalSessionFactoryBean related postings but could not find any solutions for my problem.
Here's the server.log during web application deployment and startup -

Log4j:ERROR Could not instantiate configurator

I use
-Dlog4j.configuratorClass=mypackage.Log4jConfigurator
java option in startWeblogic command file
to read changes in log4j-config.xml.
After that I have in console.log
og4j:ERROR A "mypackage.Log4jConfigurator" object is not assignable to a "org.apache.log4j.spi.Configurator" variable.
log4j:ERROR The class "org.apache.log4j.spi.Configurator" was loaded by
log4j:ERROR [weblogic.utils.classloaders.GenericClassLoader@544b02 finder: weblogic.utils.classloaders.CodeGenClassFinder@a0e9d7 annotatio

log4j:ERROR "mypackage.Log4jConfigurator" was loaded by [sun.misc.Launcher$AppClassLoader@12498b5].
log4j:ERROR Could not instantiate configurator [mypackage.Log4jConfigurator].
Could anybody help?

Did you get a resolution? I have a similar problem with a different object, org.apache.log4j.spi.TriggeringEventEvaluator, which has been loaded by the Weblogic consoleapp. I am running in a standalone server configuration -- admin and application server are the same. Also, using exploded directories.
Is there a way to prevent the WebLogic classloader from loading its version from the consoleapp?

I dont know where the problem occurs. Please help.

There should be a 'caused by' entry in your stack.
If your ejbCreate() method is connecting to the DB and this error only occurs when the DB is down - what exactly is your question?

Could not instantiate bean

Hi Guys,
I am not much familiar with Java. I have developed my java program using jdk1.6 and am trying to register java bean using jdk.1.3.1.08 sun.beans.ole.packager utility and when i reach step 5 and click register i am getting below error message. Can someone help me understand what i am doing wrong. The class file is located in excel\test\Getfileinfo.class and it does have constructor definition in it. Thanks.
c:\jdk1.3.1_08\jre>.\bin\java -cp .\lib\rt.jar;.\lib\jaws.jar sun.beans.ole.Packager
The definition for excel.test.GetFileInfo in the JAR file
has a format error.
WARNING: Could not instantiate bean "excel.test.GetFileInfo" from JAR "C:\excel.jar"
But were unable to load the class "excel.test.GetFileInfo" because of
java.lang.ClassNotFoundException: excel.test.GetFileInfo
Common reasons for this failure include:
(1) The class is not defined in the correct package
it should be in the package "excel.test"
(2) The class has not been given the correct name
it should be called "GetFileInfo"
(3) The class file contains the wrong class or no class at all

This is a very general error in spring. If the jvm cannot find the class in classpath which you have defined in your spring bean configuration file it throws this error.
Try placing the hibernate3.jar and spring-orm.jar or any other concerned jar files inside the /WEB-INF/lib directory.Only adding jar files in classpath will not suffice.
Best will be put all the jar files in the /WEB-INF/lib directory and then add the jar files in classpath from here.

BeanInstantiationException: Could not instantiate bean class

Hi,
I am working on a small part of j2ee app and creating a couple beans. Now I get stuck here:
This is my bean class:
public class KomplexniPseudoOsoba extends POsoby{
 public KomplexniPseudoOsoba() {
 super();
 public class KomplexniOsoba extends PAdresy{
 public KomplexniOsoba() {
 super();
I want the inner KomplexniOsoba class to be my bean. Now when i add it to webmvc-config.xml (using springframework) like this:
<bean id="KomplexniOsoba" name="KomplexniOsoba"
 class="cz.edu.mub.pef.ja.xkosteln.model.KomplexniPseudoOsoba$KomplexniOsoba">
</bean>
I get
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'KomplexniOsoba' defined in ServletContext resource [WEB-INF/spring/webmvc-config.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [cz.edu.mub.pef.ja.xkosteln.model.KomplexniPseudoOsoba$KomplexniOsoba]: No default constructor found; nested exception is java.lang.NoSuchMethodException: cz.edu.mub.pef.ja.xkosteln.model.KomplexniPseudoOsoba$KomplexniOsoba.<init>()
What am I doing wrong the constructor is there!

Could Not Instantiate Plug-In

I'm tring to launch FCX 3.5 on my dual 2.3 G5 and I keep getting this warning.
It used to work fine and I can't find any info on this topic.

OK, so I trashed prefs no help.
I created a new user account and launced FCX and it asked for
the "Waves plug-ins" folder.
When I targeted it and hit choose then the same error message came up.
very frustrating.... why can't I bypass the audio filters option that I don't use anyway? I have so may audio plug ins that it takes several minutes to load.

SAPJCo problem -- Could not initialize dynamic link library sapjcorfc

Hi there,
I have a J2EE application running on Websphere Application Server ND V6.1 (on MS Windows Server, Enterprise Edition with
SP2). J2EE application need to communicate to SAP on P560 z/OS via SAP Java Connector (SAP JCo). As per instructions given by
SAP JCo, I have created a folder and extracted SAPJCo zip to that, and also copied librfc32.dll & sapjcorfc.dll to
C:\Windows\system32 folder and created the shared libraries at the Application server level on Websphere to point to the
sapjco.jar file.
Now when I start my J2EE Application on Webpshere, I get hte error which is under the dashed line. The main complaint is.....
java.lang.ExceptionInInitializerError: JCO.classInitialize(): Could not load middleware layer
'com.sap.mw.jco.rfc.MiddlewareRFC'
JCO.nativeInit(): Could not initialize dynamic link library sapjcorfc [D:\Software\SAPJCo\sapjcorfc.dll (JVMPORT015E Unable
to resolve DLL references - a prerequisite DLL may be missing)].
Please let me know if any one has experienced similar problems. As we have a milestone to present this in a very short time,
I appreciate if any one could help me out as soon as possible.

Hi,
The following error is id due to the following cause :
Exception: Exception in thread "main" java.lang.ExceptionInInitializerError: JCO.classInitialize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC' default_cpc_mode at com.sap.mw.jco.JCO.<clinit>(JCO.java:309)
Exception: Exception in thread "main" java.lang.ExceptionInInitializerError: JCO.classInitialize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC' JCO.nativeInit(): Could not initialize dynamic link library sapjcorfc [C:devcu rrjcosapjcorfc.dll]. Required version "2.1.5 (2005-02-15)". at com.sap.mw.jco.JCO.<clinit>(JCO.java:735)
Exception: Exception in thread "main" java.lang.ExceptionInInitializerError: JCO.classInitialize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC' JCO.nativeInit(): Could not initialize dynamic link library sapjcorfc. Found version "2.0.11 (2005-01-21)" but required version "2.1.5 (2005-02-15)". at com.sap.mw.jco.JCO.<clinit>(JCO.java:735)
Cause: These exceptions typically occur when different versions of sapjcorfc.dll and sapjco.jar have been installed. Anytime the JCo connector is upgraded to a new version, you need to ensure that all three libraries are updated (librfc32.dll, sapjcorfc.dll, and sapjco.jar). If any are left at the older version, one of the above exceptions is likely to occur.
Resolution: Extract sapjcorfc.dll and sapjco.jar from the original JCo archive. Copy these files to the appropriate locations, overwriting the originally installed versions. Ensure that the PATH statement is updated to reflect the directory location of the DLL files and the Java CLASSPATH points to sapjco.jar.
U can use the following link to solve any problem associating JCO :

Could not locate compiled schema resource schema/system/s1130C5BD40C5682431D4FD64179031DE/index.xsb

can somebody pleas tell me why is xmlbeans looking for an index.xsb? i cant run
my java classes because it is looking for this file. how can i solve this?

Unfortunately the generated error messages are really misleading. Nevertheless
I was able to find the solution.
The orginal error message was:
Caused by: java.lang.RuntimeException: Could not instantiate SchemaTypeSystemImpl
(java.lang.reflect.InvocationTargetException): is the version of xbean.jar correct?
I tried to locacate the error somewhere in the implementation of XMLBeans, but
no success. Afterwards I included an printStackTrace() command in the code section
where the error has been thrown and the more detailed error message was:
Could not locate compiled schema resource schema/system/sC8870485F5E7AEB8A9BBEB56FEB321E8/index.xsb
Obviously the schema resource has not been compiled. Then I looked in the parameters
of scomp and found:
H:\UserData\SunONE\XMLBeans>scomp
Compiles a schema into XML Bean classes and metadata.
Usage: scomp [opts] [dirs]* [schema.xsd]* [service.wsdl]* [config.xsdconfig]*
Options include:
-cp [a;b;c] - classpath
-d [dir] - target binary directory for .class and .xsb files
Obviously the xsb Files are not generated, if the target binary directory is not
explicitly mentioned. Therefore I modified the compile command to
H:\UserData\SunONE\XMLBeans>scomp -src GenClasses -d GenClasses -out myMainData.
jar MainData21.xsd
and, voila, it works!!!!!
