I'm working on Apache Camel to build proxies. I am able to run the sample provided. But in that I have to configure camel-config.xml file manually. I want to know that whether we can configure this file programmatically to host/confgure proxies in runtime?
This is the original camel-config.xml file:
<?xml version="1.0" encoding="UTF-8"?>

This camel-config file is used to set the ApplicationContextUri as follows:
Main main = new Main();
main.setApplicationContextUri("/ApacheCamelTest2/camel-config.xml");
main.start();
How can I configure the camel-config.xml programatically at runtime?
Use DSL and create them on runtime. https://camel.apache.org/java-dsl.html
This way you have total control over the routes and you can add/modify/delete them on runtime, programatically.

I am new to the CAS setup, started using CAS 4.2.x version. With help of the below , doing the setup.
[https://apereo.github.io/cas/4.2.x/installation/LDAP-Authentication.html][1]
After adding bean reference "http://www.ldaptive.org/schema/spring-ext" in the deployerConfigcontext.xml, getting the error

I am using CAS 3.5.2 and was facing the same issue ..... the below workaround worked for me. You can give it a shot and see if it works for you as well.
Add the following dependency in your pom.xml file
<dependency>
<groupId>org.jasig.cas</groupId>
<artifactId>cas-server-support-ldap</artifactId>
<version>${cas.version}</version>
</dependency>
then remove the below lines from your deployerConfigcontext.xml
xmlns:ldaptive="http://www.ldaptive.org/schema/spring-ext"
http://www.ldaptive.org/schema/spring-ext http://www.ldaptive.org/schema/spring-ext.xsd
In your deployerConfigcontext.xml remove the ldaptive declaration and replace it with the below format.
<bean id="contextSource" class="org.springframework.ldap.core.support.LdapContextSource">
<!-- DO NOT enable JNDI pooling for context sources that perform LDAP bind operations. -->
<property name="pooled" value="false"/>
<!--
Although multiple URLs may defined, it's strongly recommended to avoid this configuration
since the implementation attempts hosts in sequence and requires a connection timeout
prior to attempting the next host, which incurs unacceptable latency on node failure.
A proper HA setup for LDAP directories should use a single virtual host that maps to multiple
real hosts using a hardware load balancer.
-->
<property name="url" value="your-ldap-url" />
<!--
Manager credentials are only required if your directory does not support anonymous searches.
Never provide these credentials for FastBindLdapAuthenticationHandler since the user's
credentials are used for the bind operation.
-->
<property name="userDn" value="your-userDn-info"/>
<property name="password" value="password-for-your-userDn"/>
<!-- Place JNDI environment properties here. -->
<property name="baseEnvironmentProperties">
<map>
<!-- Three seconds is an eternity to users. -->
<entry key="com.sun.jndi.ldap.connect.timeout" value="3000" />

<!-- Explained at http://docs.oracle.com/javase/jndi/tutorial/ldap/security/auth.html -->
<entry key="java.naming.security.authentication" value="simple" />
</map>
</property>
</bean>
Also in your deployerConfigcontext.xml remove your ldapAuthenticationHandler bean and replace it with the following
<bean class="org.jasig.cas.adaptors.ldap.BindLdapAuthenticationHandler"
p:filter="your-ldap-filter"
p:searchBase="your-search-base"
p:contextSource-ref="contextSource"
p:ignorePartialResultException="true" />
Please note that i am using CAS 3.5.2 so you might have to make some more changes ...
I've referred to the JMS page of the Camel documentation and many related SO questions such as this one, but I'm unable to find a comprehensive list on the implementation.
I'm using Spring XML along with Camel and Weblogic for the server. I've made a test queue with the following names:
Server: TestJMSServer, Module: TestJMSModule, Queue: TestJMSQueue, CF: TestConnectionFactory.
According to the Camel documentation, my route should look something like this:
<camel:route id="test">
<camel:from uri="jms:TestJMSQueue" />
<camel:to uri="file:/Users/...." />
</camel:route>
This gives me an error saying "connectionFactory must be specified". So exactly what else do I need to add to my applicationContext.xml in order to listen to this queue?
You need to tell Camel's jms-component which JMS connection factory to use. Most likely you'll get that from jndi if you're using WebLogic.
In the example below i am looking up the connection factory using spring's jee:jndi-lookup (i believe that might even be a name you can use in WebLogic). The looked up factory is then made available as a spring bean with id myConnectionFactory.
This connection factory bean is then used for the connectionFactory property for camel's JmsComponent. Notice the id attribute: jms. This defines the camel endpoint uri scheme to be used in your routes.

Important Note: You will need to tune this further (setup transactions, setup concurrent consumers, possible configure a spring jms connection pool)
My Tomcat Application is not running (never was). The Tomcat itself is running, but the application cannot be found (see screenshot):
I have the following project setup (with Spring 4.1 and Maven):

return modelAndView;
}
public List<User> loadUsers(){
List<User> list = new ArrayList<User>();
list.add(new User("User","Name","mail#gmail.com","noPassword"));
return list;

}
Can somebody help me with the setup and tell me what I forgot?

You need some way of initializing the Spring context. The easiest way is to add this to your web.xml:
<!-- location of spring xml files -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/yachtCalendarApp-servlet.xml</param-value>
</context-param>
<!-- the listener that kick-starts Spring -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
Reasons may include the following:
In your servlet you use mapping for only 3 types of patterns. May be must be
*.jsp because your screenshot consists only jsp files
You have no welcome page in your web.xml and Tomcat doesn't know about jsp files
your app is called as 'yachtcalendar' (all letters are small) but not yachtCalendar
You can try
http://localhost:8080/yachtcalendar/user
2.http://localhost:8080/yachtcalendar/user.jsp (because in your web.xml - user.jsp)
change your url-pattern to /* and http://localhost:8080/yachtcalendar/user
Could your print your UserController
I have an embedded ActiveMQ under Apache TomEE. TomEE configures JMS in a file called tomee.xml, in my case, it's configured like this
<Resource id="Default JMS Resource Adapter" type="ActiveMQResourceAdapter">
BrokerXmlConfig = broker:(tcp://localhost:61616)?persistent=true
ServerUrl = tcp://localhost:61616
DataSource = MyDataSource
</Resource>
Now, I'd like to specify custom memory settings, which is done in the activemq.xml file. TomEE can load activemq.xml configuration using Spring XBeans if I add , like this (I think)
<Resource id="Default JMS Resource Adapter" type="ActiveMQResourceAdapter">
BrokerXmlConfig = xbean:file:conf/activemq.xml
ServerUrl = tcp://localhost:61616
DataSource = MyDataSource
</Resource>
See http://tomee.apache.org/jms-resources-and-mdb-container.html
Is that right?
I've added the 5 jars into tomee's lib path, just as indicated in the link above.
And then, I have an activemq.xml like this

what am I missing here?

then I've added the absolute path to the activemq.xml file because I could not make it work from inside eclipse (I know, this is probably more like eclipse's fault)

after some google, some solutions seems to be related somehow to the incapacity of activemq to load the XML (makes sense, since XML is a recent technology, invented in 96, almost 20 years ago)
I am pulling my hair off.
I think you transport connector configuration should look like this:
<transportConnectors>
<transportConnector name="tcp" uri="tcp://0.0.0.0:61616"/>
</transportConnectors>
See the documentation for connectors.
I'm currently evaluating Spring (with a focus on WebFlow) for future projects. After reading lots of docs and articles (most of which didn't help much) I downloaded the current release of Spring WebFlow (2.3.0 at the time of writing) and tried to get the samples running. Apart from solvable, yet frustrating, dependency- and classpath-issues, I hit the first roadblock with the config-files distributed with the samples. First of all, the webflow-config.xml of the booking-mvc-sample isn't even valid.

Changing http://www.springframework.org/schema/webflow-config/spring-webflow-config.xsd to http://www.springframework.org/schema/webflow-config/spring-webflow-config-2.3.xsd removes the validation errors from Eclipse but the SAXParser still complains at startup.
Is there any way around it? Can someone help me out with a working config or point to a working tutorial (either a correct one if it's the samples fault or one that shown me how to setup SWF correctly if I'm doing it wrong)?
Right now I'm not far from dumping SWF from our list of possible frameworks as "not running out of the box" and - looking at the userbase and prevalence of Spring, this is somehow hard to believe.
Thanks a lot.
