Is it possible to reference my own properties inside the <broker> configuration portion of the activemq.xml file?
I'm setting my property values by altering the ACTIVEMQ_OPTS in the "env" script, e.g. adding something like:
ACTIVEMQ_OPTS="${ACTIVEMQ_OPTS} -Dmy.property=MyValue"
And I have the following at the start of my activemq.xml file:
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd">
<!-- Allows us to use system properties as variables in this configuration file -->
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<value>file:${activemq.conf}/credentials.properties</value>
</property>
</bean>
Configuring <beans> in the activemq.xml file works fine with my own properties in the "value", e.g. this works fine:
<bean id="myBean" class="MyClass">
<property name="someProperty" value="${my.property}"/>
</bean>
and ${my.property} is resolved perfectly ... but I just can't figure out how to get my properties to resolve when inside the <broker> element or one of it's children (like the persistenceAdapter).
For example, in the following case ...
<persistenceAdapter>
<replicatedLevelDB directory="${activemq.data}/leveldb" zkAddress="${my.zk.address}" zkPath="/activemq" bind="tcp://0.0.0.0:0" weight="${my.weight}"/>
</persistenceAdapter>
... the ${activemq.data} property is resolved ... but I can't seem to figure out how to get any of my own properties to resolve within the <broker> element of the activemq.xml configuration file ... I just keep getting an error that '${my.weight}' isn't a valid number (which is kind of insulting, if you think about it ;-)
I am stuck with the same problem
Got it to work but not sure if that is the right way.
You have to add it to the startup scripts.
If you are using active.bat
"%_JAVACMD%" %ACTIVEMQ_SUNJMX_START% %ACTIVEMQ_DEBUG_OPTS% %ACTIVEMQ_OPTS% %ACTIVEMQ_SSL_OPTS%
-Dactivemq.classpath="%ACTIVEMQ_CLASSPATH%"
-Dactivemq.home="%ACTIVEMQ_HOME%"
-Dactivemq.base="%ACTIVEMQ_BASE%"
-Dactivemq.conf="%ACTIVEMQ_CONF%"
-Dactivemq.data="%ACTIVEMQ_DATA%"
-Djava.io.tmpdir="%ACTIVEMQ_TMP%"
-D**remote.host.ip=1.2.3.4**
-jar "%ACTIVEMQ_HOME%/bin/activemq.jar" %*
If you are using wrapper, add it to wrapper.conf
wrapper.java.additional.**13**=-Dremote.host.ip="1.2.3.4"
Make sure to increment bolded number.
Yes, you can use property placeholders to load a properties file or use environment variables. It looks like you are using Spring, so you'd need to use the Spring-specific property placeholder mechanism.
Property file:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="properties">
...
Environment variables:
<context:property-placeholder />

I managed to save and load spark dataframe from ignite by the example here: https://apacheignite-fs.readme.io/docs/ignite-data-frame
By following the code example when the cache is created in ignite it automatically has a name like "SQL_PUBLIC_name_of_table_in_spark".
One the other hand if I want to change some cache configuration I need to specify the same cache name in xml or code before creating ignite cache. Because cache configuration can not be changed after cache is created. See following code.
<bean class="org.apache.ignite.configuration.IgniteConfiguration">
<property name="cacheConfiguration">
<bean class="org.apache.ignite.configuration.CacheConfiguration">
<!-- Set a cache name. -->
<property name="name" value="SQL_PUBLIC_name_of_table_in_spark"/>
<!-- Set cache mode. -->
<property name="cacheMode" value="PARTITIONED"/>
</bean>
</property>
</bean>
Then one of them will be reject by "cache already exists" The result is I could't change any cache configuration by xml/code.
Is this expected? And how can I change the cache configuration in this case?
The doc page you've link contains a code piece that creates an SQL table:
CREATE TABLE person (
id LONG,
name VARCHAR,
city_id LONG,
PRIMARY KEY (id, city_id)
) WITH "backups=1, affinityKey=city_id”;
This SQL command is what actually creates the cache. You can change this command to change the parameters of the cache that will be created. Refer to the CREATE TABLE doc.
In particular, the parameter that gives the most flexibility is WITH template=mytemplate. It lets you create a cache from a pre-existing template configuration. To register a template you can specify it in your cacheConfiguration with a name ending with asterisk, like
<bean class="org.apache.ignite.configuration.IgniteConfiguration">
<property name="cacheConfiguration">
<bean class="org.apache.ignite.configuration.CacheConfiguration">
<property name="name" value="mytemplate*"/>
<!-- your parameters. -->
</bean>
</property>
</bean>
You can also specify the WITH parameters for CREATE TABLE in the OPTION_CREATE_TABLE_PARAMETERS setting if the table is being created automatically by Spark.
I want to do a whitelisting of what properties are indexed/searched and shown in excerpt with a Magnolia search.
I am changing the indexing_configuration.xml in my website workspace.
Removing the index and restarting magnolia did not change anything...
By now I have this in my indexing_configuration.xml (next to other stuff)
but these are the String properties I want to include in my ecxcerpt the rest should be excluded:
<index-rule nodeType="nt:hierarchyNode">
<property boost="10" useInExcerpt="true">introTitle</property>
<property boost="1.0" useInExcerpt="true">introAbstract</property>
<property boost="1.0" useInExcerpt="true">contentText</property>
<property boost="1.0" useInExcerpt="true">subText</property>
<property boost="10" useInExcerpt="true">title</property>
<!-- exclude jcr:* and mgnl:* properties -->
<property isRegexp="true" nodeScopeIndex="false" useInExcerpt="false">.*:.*</property>
</index-rule>
<index-rule nodeType="mgnl:contentNode">
<property boost="5" nodeScopeIndex="false" useInExcerpt="true">introTitle</property>
<property boost="2" nodeScopeIndex="false" useInExcerpt="true">introAbstract</property>
<property boost="2" nodeScopeIndex="false" useInExcerpt="true">contentText</property>
<property boost="2" nodeScopeIndex="false" useInExcerpt="true">subText</property>
<property boost="5" nodeScopeIndex="false" useInExcerpt="true">title</property>
<!-- exclude jcr:* and mgnl:* properties -->
<property isRegexp="true" nodeScopeIndex="false" useInExcerpt="false">.*:.*</property>
</index-rule>
How can i get this to work as intended? Thanks for your help..
Most likely cause is that Magnolia/JR is not seeing your new configuration. Did you change your repo configuration (workspace.xml in website workspace) to point it to new index configuration?
Default looks like:
<SearchIndex class="org.apache.jackrabbit.core.query.lucene.SearchIndex">
<param name="path" value="${wsp.home}/index" />
<!-- SearchIndex will get the indexing configuration from the classpath, if not found in the workspace home -->
<param name="indexingConfiguration" value="/info/magnolia/jackrabbit/indexing_configuration.xml"/>
and you need to point it to your new file.
Also not sure why you are setting indexing based on nt:hierarchyNode or mgnl:contentNode rather then using more specific mgnl:page/mgnl:component
In mule I have many applications running on the same container that access a jdbc connector with the same connection string/user/password set.
Of course any app has configured the same global connector in its xml configuration file, so there is code duplication.
Is there a way to define only once per container the connection and access it from any app?
I would try this: have one app create the datasource and store it in JNDI and have the other apps pick it up from JNDI.
Since there is no strong guarantee of app start ordering, it's possible that one app that needs the JNDI datasource would start too soon. You would need to configure Spring to be able to perform the JNDI lookup again in case of failure and configure a threaded retry policy on the Mule JDBC connector.
Also you will need to install the datasource and database JARs in lib/user so all apps could use them.
Just create a spring bean for your JDBC connector in xml some where in your system and have all your applications load it in your apps:
<spring:import resource="JDBC-beans.xml" />
and the 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"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd ">
<!-- Initialization for data source -->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/TEST"/>
<property name="username" value="root"/>
<property name="password" value="password"/>
</bean>
</beans>
I have solved this kind of problem using a Domain project, where I inserted all database configurations that have been used by other projects.
I am very very new to Apache Camel and I am looking to create a simple application which reads 200 products from mysql db 1 and then inserts the products into mysql db 2. No changes required to the data, it is just a one for one bulk select and then bulk insert.
I have been looking at the camel-sql-example project which uses the sql component. I like the way it's structured so I've attempted to go with this example project as my base.
Would anyone be able to help me with the location of a good example for this or giving me a rough indication of what my camel route (spring arcehtype) should look like?
Is something like this correct?
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<property name="dataSource" ref="sourceDataSource"/>
</bean>
<bean id="targetSql" class="org.apache.camel.component.sql.SqlComponent">

<route id="processProduct-route">

<log message="${body}"/>
</route>
</camelContext>
thanks
I tested this today and what I've specified above seems to work! Something that I did not expect though was that the route just loops and continues to run multiple times. I only need it to run once. I'm looking into how to achieve this.
I have written a simple authentication/authorization plugin that I want to inject into ActiveMQ. I want it to be called onConnect and onSubscribe. I have followed these steps at the ActiveMQ website but a couple of things happen.
1) If I put in my bean declaration in the default activemq.xml file in //beans/broker/plugins I get a validation error saying that the node "bean" is not allowed there.
2) If I put the plugin declaration outside of the broker element it will inject the element, but it will not call installPlugin() nor the hooks, presumably because that is for the broker to do.
3) If I change the XML namespace declaration in the default activemq.xml (http://activemq.apache.org/schema/core) to that which is stated in the docs listed above (http://activemq.org/config/1.0) along with the proper URLs, I get the error that it cannot find the schema document.
The only thing I can come up with is that either there were changes in 5.6 that were not reflected in the documentation, I'm doing something very wrong, or I'm just crazy. Here is the relevant portion of the xml doc (minus several nodes not directly related to the problem).
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:amq="http://activemq.org/config/1.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd">
<broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}">
<plugins>
<bean id="tokenLoginPlugin" class="auth.TokenLoginPlugin">
<property name="host" value="localhost" />
</bean>
</plugins>
</broker>
This generates the following exception.
The matching wildcard is strict, but no declaration can be found for element 'broker'.
If I use the xmlns declarations from the default activemq.xml file, I get the following.
Invalid content was found starting with element 'bean'
I can see that it's a validation error, but none of the docs seem to be pointing me in the right direction.
Figured it out, though I had tried it before and it hadn't worked. Perhaps I had messed up my namespaces the last time. I changed my plugin definition and added the Spring namespace to my bean declaration.
<plugins>
<bean id="tokenLoginPlugin" class="auth.TokenLoginPlugin" xmlns="http://www.springframework.org/schema/beans">
<property name="host" value="localhost" />
</bean>
</plugins>
