--- Not Important ---
Hi, this is my first question and I'm not really good at english, so I'm sorry if I don't explain myself well.
I'm currently starting to learn Java Web with Spring Framework from free online courses, but almost everytime I write the code that the teacher writes, I get exceptions and have to search the problem on Google, this time I got an error that I didn't find.
--- Important ---
I'm trying to automatically "import" beans from a package in order instead of "import" them manually (I write them with quotation marks because I don't know what is the word for that) but when I run the code I get this exception:
Unexpected exception parsing XML document from class path resource [beans.xml]; nested exception is java.lang.NoSuchMethodError: 'java.lang.String org.springframework.util.StringUtils.uncapitalizeAsProperty(java.lang.String)
And this is my beans.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:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
https://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:component-scan base-package="com.principal"/>
</beans>
I don't have any idea what's going on, so I hope you guys can help me, thanks in advance, you're awesome c:

I have a lot of errors in my project and they won't go off and I know that they are related to Dependency related stuff but I'm confused. Can someone tell me how to fix this if you have also faced the same kind of issue?
Try out this one in your XML:
We use JPA namespace for XML based enabling like below:
<?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:jpa="http://www.springframework.org/schema/data/jpa"
xsi:schemaLocation="http://www.springframework.org/schema/beans
https://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/data/jpa
https://www.springframework.org/schema/data/jpa/spring-jpa.xsd">
<jpa:repositories base-package="path.to.repository.package" />
</beans>
I am creating a apache-camel spring dsl application.
In the camel-config.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:camel="http://camel.apache.org/schema/spring"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd">
This is showing error

Do you have more than just this piece of xml, I bet your error is in some invalid xml you have typed yourself. There is plenty of Spring + Camel XML examples out there you can take look at, that works, for example:
https://github.com/camelinaction/camelinaction/blob/master/chapter2/spring/src/main/resources/META-INF/spring/camel-context.xml
I'm making my first forays into spring and am getting the following error trying to run on eclipse:
org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'model' must be of type [com.myCompany.project.Model], but was actually of type [com.myCompany.project.Model]
Code causing the exception:
import com.myCompany.project.Model;
// some code
public Model getModel() {
ClassPathXmlApplicationContext applicationContext =
new ClassPathXmlApplicationContext("client-context.xml");
return applicationContext.getBean("model", Model.class);
}
Spring 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:context="http://www.springframework.org/schema/context"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:annotation-config />
<bean id="model" class="com.myCompany.project.Model" />
</beans>
The client-context.xml is located in project/resources, the code in project/src/main/
I assume this is a classpath issue, but I am at a loss as to what to do to fix it.
Java and Spring are case sensitive. This:
<bean id="model" class="com.myCompany.project.model" />
is not the same as this:
<bean id="model" class="com.myCompany.project.Model" />
I'd think about some better names. Those aren't very insightful.
I don't like the way you're going about this. You shouldn't have a bean that has to access the app context this way. You'll have to post more code to be sure, but you ought to be wiring that model bean into object that wants it, not doing what you're doing.
The only reason for doing what you're proposing is if the bean interacting with the app context is creating using new rather than the Spring bean factory. Since you're just starting with Spring, I would recommend letting Spring handle all dependencies.
I want to use spring together with jbossws-cxf. Is this possible?
First I tried using jbossws-cxf.xml with bean definitions of spring. The warning message [DescriptorDeploymentAspect] Spring not available, skipping check for user provided jbossws-cxf.xml / cxf.xml configuration files. states that the file gets ignored and means that you should install spring in order for it to not get ignored :-) . So I installed spring for jboss..
After installation and running of a simple MathWS together with a simple WS example I get a
[org.jboss.wsf.stack.cxf.client.configuration.JBossWSSpringBusFactory] INITIAL_APP_CONTEXT_CREATION_FAILED_MSG: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.apache.cxf.binding.soap.customEditorConfigurer' defined in URL [vfs:/D:/lifeDevSuite/jboss/jboss-6.0.0.FinalSpring/common/lib/cxf-rt-bindings-soap.jar/META-INF/cxf/cxf-extension-soap.fixml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'java.util.ArrayList' to required type 'org.springframework.beans.PropertyEditorRegistrar[]' for property 'propertyEditorRegistrars'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [org.apache.cxf.binding.soap.spring.SoapVersionRegistrar] to required type [org.springframework.beans.PropertyEditorRegistrar] for property 'propertyEditorRegistrars[0]': no matching editors or conversion strategy found
error.
My jbossws-cxf.xml looks like this:
`
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:jaxws="http://cxf.apache.org/jaxws"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/jaxws
http://cxf.apache.org/schemas/jaxws.xsd">
<bean id="mathBean" class="com.sample.MathWS">
<constructor-arg value="alabama" />
</bean>
<jaxws:endpoint id="MathWSX" implementor="#mathBean" address="http://localhost:8080/HelloCXF" />
`
I solved the problem. Sadly - I cannot recall how. And please forgive me - but I'm not going back to try and reproduce it :-)
Basically the answer is "yes". To that specific problem, it may have been a namespace problem, e.g. correct would be
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:jaxws="http://cxf.apache.org/jaxws"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-2.5.xsd
http://cxf.apache.org/jaxws
http://cxf.apache.org/schemas/jaxws.xsd">
It may have been as well that custom spring libraries were deployed (I think it is recommended using the spring libraries coming with jboss and are deployed dynamically automagically)
It may have been something else alltogether
I'm trying to learn Spring, Hibernate and Webflow.
Why is it that when I add beans to my applicationContext i get a 404 when I run the project.
Here's my context config:
<?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:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<bean id="roleService" name="roleService" class="ws.Service.RoleServiceImp" />
</beans>
Now when I add another bean, it goes 404. I'm not sure what's wrong. i.e:
<bean id="userService" name="userService" class="ws.Service.UserServiceImp" />
Am I missing something? Any help will be appreciated.
If an Web Spring Application can not start, for example if the context-xml contains a bean that does not exist, or a syntax error, then Spring will not "start" the context.
If you have a spring web application and the application does not start then, the whole spring web request handling stuff does not too. And when you not try to access an web page normally handled by the spring controllers the web server can not found this handler, so the web server says: not found - 404.
that is the answer to your question: "Why is it that when I add beans to my applicationContext i get a 404 when I run the project."
Anyway I believe you are more interested in why the application did not start:
have a look in the logs, there must be a stack trace
if you did not find the problem, with help of the stack trace, then add it to your question (or ask a new one).
