Weblogic 10 spring bean intialisation problem
I am having 2 ear file deployed in one weblogic 10 server. Each ear file contains same spring bean(e.g "fsiAuthService" bean) definition under applicationContext.xml file belongs to each ear. But while deploying both the ear file in weblogic 10, I am getting exception with bean initialisation failure. It seems, once bean initialisation done for first ear file, we are not able to intialise same bean for second ear file. But I am able to deploy both the ear file successfully in weblogic 9.1, 9.2 version. It seems, there is some issue with weblogic 10. Can anyone explain why this problem is occuring with weblogic 10? Please find below the exception detail getting for weblogic 10:
<HTTP> <BEA-101162> <User defined listener org.springframework.web.context.ContextLoaderListener failed: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'fsiAuthService' defined in ServletContext resource [WEB-INF/applicationContext.xml]: Instantiation of bean failed; nested exception is java.lang.ExceptionInInitializerError.

It's likely that the stack trace in the server log will provide the "root cause" of the exception (whether that's really the root cause or not). That might be helpful.

Using Spring beans from EJB MDB
I have a situation where I need to use spring beans from an EJB 3.0 MDB. The project does not have any webapps or anything,
it will be only a MessageBean facade that needs to call spring beans. It is meant to be a service, that can be called by usign a single EJB message.
The problem is I cannot get the spring context to load properly, since the MDBean it self is initialized(constructor called) only when it receives the first message from the broker, thus It's "too late" to initialize the spring context. What I want to do is load the spring context when the EJB is deployed in the Java EE container. So, is there a way I can call a some method, class, anything when the EJB is deployed in the container. Can I do something with a deployment descriptor?
I am using glassfish V2 UR1, EJB 3.0, Spring 2.0.7 The project is deployed as a jar.Miku wrote:

DelegatingVariableResolver not resolving Spring beans
I'm developing an application using ADF UI + Spring using Jdveloper11g and deploying it to Weblogic 10.3. I'm creating beans in Spring and injecting them into ADF as managed beans(via faces-config.xml). My faces-config.xml looks like:
-------------snip-----------------------
<?xml version="1.0" encoding="windows-1252"?>
<faces-config version="1.2" xmlns="http://java.sun.com/xml/ns/javaee">
<application>
<default-render-kit-id>oracle.adf.rich</default-render-kit-id>
<variable-resolver>org.springframework.web.jsf.DelegatingVariableResolver</variable-resolver>
</application>
<managed-bean>
<managed-bean-name>engineAspect</managed-bean-name>
<managed-bean-class>com.x.EngineAspect</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>engineAspect</property-name>
<value>#{engineAspect}</value>
</managed-property>
</managed-bean>
</faces-config>
-------------snip-----------------------
I'm using a backing bean to call a method on the engineAspect bean when some action happens in the UI. But, the line System.out.println(engineAspect); in the backing bean always prints a null. The backing bean has getter and setter for this field. Yet, the bean is not resolved from Spring. Any ideas what may be missing from the configuration?Miku wrote:

Weblogic, Spring, EAR, EE container, how to start spring container?
Hi, I'm a bit stuck and although googled for quite a while, haven't found any hint on how to achieve the following. (If someone notice, yeah, I've posted same question on spring forums :) )
I have some jar which contains spring beans which so far operated as
standalone app by simply starting spring context. Spring context config is within jar, but it could be moved out if required.
Now, I'm trying to embed it into EAR and to deploy to EE container (it is WebLogic server, thus I am posting here)...and it is fine, I've embedded it as javaModule and deployed it,
but of course it doesn't do anything as spring context is not started.
That is my question, does someone has experience with this? All I need is to on EAR start, to start spring context and on EAR stop to stop it...
This does not have any gui or anything so I don't need it to be webapp. Also there are no EJBs as I don't need them, this app actually occasionally calls some system command to process some files.
I am aware that maybe I'd need to extend ApplicationLifecycleListener but if so, what would be good approach to start context and keep it alive until EAR is stopped?
I am aware that I could convert it to web-app and use ContextListener on web-app, but before that I'd like to check, is this achievable,
and what is the best approach to start spring context if I only need container to be started, nothing else?
Furthermore, if I implement singleton service (as I don't need this to be spread throughout cluster) what would be the best approach to start spring context from it?
Any help/tip/info/suggestion is very appreciated.
Thanks.Well, I've actually solved it meanwhile without webapp stuff.
Perhaps if you are experienced with weblogic could evaluate my solution.
I've implemented application lifecycle listener and in post start I start spring
with ClassPathApplicationContext.start (by giving it config location) and stop it in pre stop.
Not sure if this is the best solution but it works quite fine.
Thanks,

When to use Custom Adapter, Event Beans and Spring beans
Hi,
I have basic question on when or on what basis/scenario the Custom Adapter, Event Beans or Spring beans should be used.
All three has same implementation methods.
Please help me in understanding when to use Custom Adapters, Event Beans or Spring beans.
Thanks,
Sri
Edited by: 897694 on Mar 7, 2012 8:12 AMcustom adapters:
you have to use a custom adapter when you don't find any adapter in ocep which will serve your purpose.
Most of the times you use an adapter to connect the application with external things like http server, etc It can be both to listen the events or to send the events outside.
Event Beans:
This type of beans does most of the work that an adapter code does but in convention beans are not used to connect the application with external stuff
You can use Beans as event sink etc In this case using an using an adapter is not suggestable.
If you implement Interfaces like Initializing Bean for an adapter code it won't work properly, you have to use an event Bean in that case.
Spring beans:
Spring beans are used when the bean code doesn't implement EventSink or EventSender.
These beans are used to enable something (eg: make ${wlevs_dev_home}/abc/a/b.java this path is not understandable by java code unless you override the path using a spring bean)
Most of the things which doesn't need a connection between components in the application (eg cache loader: you can do this using spring beans and event beans both but spring beans doesn't need a connection with cache)
Hope this small writeup helps you :)

EJB calling Spring Bean with non XA Datasources causing Rollback Exception
We have an EJB CMT with Required calling a spring bean (@Transactional Propagation.NOT_SUPPORTED). This is causing an Rollback Exception saying 2 phase commit must be enabled. The EJB has to write to datasource 1, but the Spring Bean is ready only on Data Source 2. The Data Sources are set to use Non XA Driver with Support Global Transaction enabled for One phase commit. Any help is appreciated.

Spring Bean not loading in Coherence 3.5
Hi,
I am upgrading my application from Coherence 3.4 to 3.5. But when I put jar files for 3.5 on application start Coherence is not able to find the spring bean. I checked the spring application context. The bean which I am reffering s present in context. The spring config is loaded before the coherence config file is loaded.
Below mentioned is the error which I am getting

ThariqHi Paul,
Thanks for the reply.
I am doing that programmatically. Below mentioned is the code.
loadSystemProperties(connectionProps);
InputStream is = Thread.currentThread().getContextClassLoader().getResourceAsStream(fileName); //coherence cache config file.
XmlDocument xmlDocument = XmlHelper.loadXml(is);
SpringAwareCacheFactory defaultConfigurableCacheFactory = new SpringAwareCacheFactory();
defaultConfigurableCacheFactory.setBeanFactory(currrentContext); //Spring injected context
defaultConfigurableCacheFactory.setConfig(xmlDocument);
CacheFactory.setConfigurableCacheFactory(defaultConfigurableCacheFactory);
CacheFactory.ensureCluster();
When I put jar files of Coherence 3.4 its loading spring beans properly. But when I put Coherence 3.5.1 everything breaks.
Thanks,

Weblogic 5.1 SP9 problems with MAC OS 9 w/ MRJ 2.2.5 [InterruptedIOException]
Hello all,
We're having a problem with one of the beans running on our WebLogic server.
A quick summary:
The application is a standalone java application that
interfaces with a Weblogic 5.1 SP9 running on a Solaris box.
The clients are a mix of Windows machines and Mac OS 9 (with OS X
coming down the line, but that is not feasible at this time
to consider a massive upgrade). Due to the limitations
of the JVM for OS 9, we are forced to run MRJ 2.2.5 on the
Mac and JRE 1.1.9 on the Windows machines.
The general flow of data is a request is made from the client app
to the WebLogic bean. The bean calls another class method which
retrieves data from the the backend database (Sybase or SQL Server 2000).
We've verified that the data comes back from the query, is placed
in an array, and is in the same state when the EJB prepares to 'return'
the data to the client. This works as expected on the Windows machines,
however, every so often, the Macs will give an
InterruptedIOException: send timed out error. Once the server times
out (after 240 seconds), the client can continue until the next
error.
A few additional pieces of info.
The data returned is an array, but there isn't any consistancy to the
size of the data set. Some will be single element arrays while others
will have 8-10 elements. The amount of data in each element is only
a string of a couple hundred characters, so it is not a large data
stream. Systems on the same network segment can go for a while (sometimes
going on 10 minutes) before getting this error, while remote offices
going over slower links will get an immediate InteruptedIOException.
We have a process in place that if it catches an InterruptedIOException
it loops and tries the procedure again, however a 4 minute wait
between loops just isn't acceptable. We tried lowering this by
placing the following lines into our weblogic.properties file:
weblogic.system.periodLength=15
weblogic.system.idlePeriodsUntilTimeout=4
However, this has had zero impact on the timeout. Are there programatic
ways of changings these values? Or to force a blocking connection that
will force the data pipe to stay open? Has anyone had any insight into
any similar problems? Unfortunately, due to the size of the company,
the environment is fixed, and no mass upgrades are a vaiable option.
Thanks all!
CliffHi Cliff,
it seems as if we have a similar problem within WLS51sp13 and a Java
Client (Servlet within Tomcat). We found that an EJB Stub within the
Client App has a 180s timeout, if the server socket didn't close
(Network problem or similar). I friend gave me a hint setting this
parameter on both sides, client and Server: It works. It seems as if the
server takes the bigger value of both values set.
Greetings,
schnaggy:-)

Message Driven Bean Reference Problem
Hi,
I have problems a MDB referencing other beans, I am getting Class Cast
exception whenever my MDB tries to use narrow operation after the lookup
is done.
The Code is as follows:
public void ejbCreate () throws CreateException {
log("ejbCreate called");
try {
InitialContext ctx = new InitialContext();
Object ref = ctx.lookup("java:comp/env/ejb/LoggerCache");
log("Lookup of Cache done");
LoggerCacheHome loggerCacheHome = (LoggerCacheHome)
PortableRemoteObject.narrow(ref, LoggerCacheHome.class);
} catch(Exception ex) {
ex.printStackTrace();
The lookup is successful but when I try to use the narrow..... I get the
following exception stackk Trace.
Any help will be appreciated.
TIA,
Vikas

Spring bean creation fails when statefull ejb created in other component
Hi All,
We have two components A and B. A creates stateful ejb as well calls B.
B inturn loads the beans using spring. While component B is trying to create the beans the following error is coming:
Error creating bean with name 'dataSource' defined in file ....
Invocation of init method failed; nested exception is java.lang.SecurityException: [Security:090398]Invalid Subject: principals=[weblogic, Administrators]
This happens only when A is using stateful beans.
when the flow uses A's stateless beans this is working fine.
For stateful beans, we are setting the Initialcontext. Has anyone faced this issue.
Env: Weblogic 10.3.2
Thanks and Regards

WebLogic RMI UNIX Performance problem
Hi.
I'm experiencing problems with the performance of RMI calls from within session
beans to external RMI services. I have a system running 4 RMI services in separate
JVMs to weblogic 6.1 instance on Solaris 2.6 on SPARC boxes with 1+ Gb of RAM.
The system was developed on NT and deployed to UNIX. A typical request is serviced
in 70-90 ms on the NT development box (Desktop 512Mb RAM) but when deployed to
the UNIX box takes anywhere between 500-4000 ms. Performance metrics in the code
indicate that 'crunch' times are similar but remote RMI calls are orders of magnitude
greater.
Has anybody had similar problems? I have checked the tuning guides wrt TCP/IP
configurations but would not expect such a large difference using the default
Solaris configuration. Memory and CPU utilisation on the SPARC are low as are
I/O and other metrics available from vmstat.
Cheers
PeteHi.
The JVMs are running on the same machine thus should be looking in /etc/hosts
and not going via DNS.
I have read there is a performance gain by tying WL to a single CPU, any insight?

worse a reverse lookup. You might want to try using IP addresses in
your config to see if that helps.

Fonts showing up in TextEdit but not in Apple apps
Hi all I have a version of the fonts issue that seems well discussed on these and other pages, which is this: I have installed a couple of fonts. They show up in Font Book. They also show up in TextEdit. But they don't show up in Pages, Keynote etc.
