Weblogic Spring Dependency Injection from flat-files on the file-system - spring

I have an application deployed into Oracle Weblogic 10.3. In my .ear files, I use spring injection from xml files in the ear files. I would like to also perform dependency injection from xml files placed on the server file-system. We do something similar to this in Karaf, where we place our configuration files for bundles in the conf directory in the server itself. Is there a similar way to do this in weblogic?

You can ask spring to read properties from file systems as below;
<!-- Reads application properties and uses them in the application context -->
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="ignoreResourceNotFound" value="true"/>
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
<property name="locations">
<list>
<value>file:D:\somefolder\application.properties</value>
<value>classpath:com/foo/sp.properties</value>
</list>
</property>
</bean>

Apache Camel Spring DSL, referring to an environment variable HOSTNAME

I am using Apache Camel 2.16.0 with Spring DSL
I have a Spring context XML in which I have defined a Property PlaceHolder to read the properties from various files as follows-
<bean id="propertyPlaceholder" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
<property name="ignoreResourceNotFound" value="false"/>
<property name="locations">
<list>
<value>classpath:/properties/versioning.properties</value>
<value>classpath:/properties/#{inetAddress.hostName}.properties</value>
</list>
</property>
</bean>
<bean id="inetAddress" class="java.net.InetAddress" factory-method="getLocalHost"/>
The property values are used to construct other beans such as -
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="org.gjt.mm.mysql.Driver"/>
<property name="url" value="${${LIVE_}DATASOURCE_URL}"/>
<property name="username" value="${${LIVE_}DATASOURCE_USERNAME}"/>
<property name="password" value="${${LIVE_}DATASOURCE_PASSWORD}"/>
</bean>
This works fine, I can see the beans being created.
I also have another Spring Context XML in the same app which has a camel context and I want to use the some other properties defined in the same properties files. I know that camel supports Spring Property Placeholder, see below excerpts from the context -
<camelContext id="charge-process-context" xmlns="http://camel.apache.org/schema/spring">
<propertyPlaceholder id="properties"
location="classpath:/properties/versioning.properties,
properties/${env:HOSTNAME}.properties"
xmlns="http://camel.apache.org/schema/spring" />
.....
.....
</camelContext>
As part of this context, I have a route that uses https component that uses the values from the property file such as below -
<to uri="https4:{{LIVE_AUTH_RESPONSE_HOST}}:{{LIVE_AUTH_RESPONSE_PORT}}/{{LIVE_AUTH_RESPONSE_CONTEXT_PATH}}"/>
This route does not start and throws following exception -

Please Note: I am deploying my application as a war file on Tomcat 8 on an AWS instance.
I have a Dev Environment on Windows 10 and I have found this working on the Windows OS. I have also seen that the file FilePathResolver.java in Apache Camel 2.16 uses System.getenv(key) to obtain the value i.e. System.getenv("HOSTNAME") which returns a null on AWS instance and a correct value on Windows 10. I also tried using env:hostname (small case letters for unix) but still no luck ...
I found a solution at http://camel.apache.org/using-propertyplaceholder.html
at Bridging Spring and Camel Property Placeholders
It mentions following -
The Spring Framework does not allow 3rd party frameworks such as Apache Camel to seamless hook into the Spring property placeholder mechanism. However you can easily bridge Spring and Camel by declaring a Spring bean with the type org.apache.camel.spring.spi.BridgePropertyPlaceholderConfigurer, which is a Spring org.springframework.beans.factory.config.PropertyPlaceholderConfigurer type.

Apache Ignite not resolving properties in configuration XML

I am looking to load a number of values into my server configuration.xml from a properties file.
However, on adding the placeholders I start getting, property cannot be resolved errors. Preferably I would like to use Jasypt, which has loaded up fine, but has the same issue, property cannot be resolved.
Sample placeholder:
<bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="ignite.properties"/>
</bean>
Sample Bean:
<property name="sslContextFactory">
<bean class="org.apache.ignite.ssl.SslContextFactory">
<property name="keyStoreFilePath" value="ignite.jks"/>
<property name="keyStorePassword" value="${some.password}"/>
<property name="keyStoreType" value="JKS"/>
<property name="protocol" value="TLSv1.2"/>
<property name="trustManagers">
<bean class="org.apache.ignite.ssl.SslContextFactory" factory-method="getDisabledTrustManager"/>
</property>
</bean>
</property>
Is it possible, is there a library I should have added, it otherwise runs fine if I do not use properties.
The configuration is parsed by Spring and Ignite has nothing to do with it. I believe there are two possible reasons:
Incorrect file path. Note that if the file is on the classpath, the location should be classpath:ignite.properties.
Incorrect property name.

Spring JNDI datasource not recognized after upgrade to ActiveMQ 5.6.0

I tested a ActiveMQ 5.5.0 (fuse version) app in AMQ 5.6.0 and noticed that our Spring JNDI configured Oracle datasources aren't being found.
The only thing I changed in my applications was the pom.xml versions of AMQ/Spring (to match the 5.6 versions). Otherwise, I'm using the identical application code and configuration (activemq.xml, jndi.xml, etc), but my Spring JDBC DAOs (v3.0.5) are failing to find them.
No errors in the logs otherwise, just this Spring Application Context initialization error...
javax.naming.NameNotFoundException; remaining name 'jdbc/myDataSource'
here is the relevant Spring jndi config (conf/jndi.xml, included in conf/activemq.xml)...
<bean id="jndi" class="org.apache.xbean.spring.jndi.SpringInitialContextFactory"
factory-method="makeInitialContext" scope="singleton">
<property name="entries" ref="jndiEntries" />
</bean>
<util:map id="jndiEntries">
<entry key="jdbc/myDataSource">
<bean id="myDBCPDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="oracle.jdbc.OracleDriver" />
...
then my application references it like this...
<bean id="myDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName">
<value>jdbc/myDataSource</value>
</property>
</bean>
<bean id="messageDAO" class="com.mycompany.MessageDAOImpl">
<property name="dataSource" ref="myDataSource" />
</bean>
That said, I tested without using JNDI (instead just hardcoded the datasource in my app) and everything works as expected. So that should rule out everything except the Spring JNDI registration/lookup of the datasource, etc.
So, what am I missing?
ActiveMQ has a dependency into xbean-spring, which you are using as a JNDI provider. It is likely that the transitive Xbean dependency has changed because of the upgrade to ActiveMQ 5.6.0.
I found the issue, I added a jndi.properties file under the /conf directory containing the following and it works fine now (didn't need this under AMQ 5.5...strange)...
java.naming.factory.initial = org.apache.xbean.spring.jndi.SpringInitialContextFactory

Spring PropertyPlaceholderConfigurer not replacing placeholder

I want to pass the WSDL url for an internal web service into my Spring beans.xml dynamically, using a PropertyPlaceHolderConfigurer.
Here's the scenario:
My web application is deployed in WebLogic 10.3.
The WSDL url is contained in a properties file that is located outside my application (directly under the corresponding domain folder, while my application is inside the autodeploy folder). I set the location of this properties file in my domain's setDomainEnv.cmd file like below:
set JAVA_PROPERTIES=%JAVA_PROPERTIES% %CLUSTER_PROPERTIES% -Dproperty.file.path.config=%DOMAIN_HOME%\Service.properties
This is what my Service.properties file contains:
Service.WSDL.PATH=http://localhost:8088/mockServiceSoap?WSDL
My Spring beans.xml configuration:----
<bean id="file.path" class="java.lang.System" factory-method="getProperty">
<constructor-arg index="0"><value>property.file.path.config</value></constructor-arg>
</bean>
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" ref="file.path"/>
</bean>
<bean id="myServiceId" class="com.test.service.ServiceImpl">
<property name="myServiceSoap">
<ref bean="myService"/>
</property>
</bean>
<bean id="myService" class="org.springframework.remoting.jaxws.JaxWsPortProxyFactoryBean">
<property name="serviceInterface" value="com.test.service.ServiceSoap"/>
<property name="wsdlDocumentUrl" value="${Service.WSDL.PATH}"/>
</bean>
I enabled DEBUG log specifically for PPC and this is what I saw in my application log:
INFO org.springframework.beans.factory.config.PropertyPlaceholderConfigurer 178 - Loading properties file from URL [file:D:/bea10.3/user_projects/domains/my_domain/Service.properties]
So, it seems that although the Service.properties file is getting loaded by PPC, the ${Service.WSDL.PATH} is NOT getting replaced.
What am I doing wrong here?
Also, how can I find out if PPC tried replacing the value of the placeholder and with what value? I was hoping the log file would contain that info but there was nothing there.
Any help is appreciated.
I've figured out, that PropertyPlaceholderConfigurer needs to be declared first in the application Context file, otherwise there's no guarantee of the load order. It took me a few hours to realize this.
Try moving the "file.path" bean into the PropertyPlaceHolderConfigurer's location property.

Weblogic classpath and Spring Resources

I'm trying to set a bean property like this:
<bean id="threadImport" class="com.foo.bat.util.ThreadImport" singleton="false">
<property name="mailSender" ref="mailSender"/>
<property name="parseConfFile" value="classpath:parse/import.xml" />
<property name="logFilename" value="/tmp/import.log" />
but none of files are found. What's the classpath for my deployed application? May I set it on any weblogic xml descriptors? Which is the best way to place and locate files used on spring applications?
I am using:
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:foobar-config.properties" />
</bean>
The properties file is either location at the root of my test source folder so JUnit has a test-specific config available and in production, we have added a classpath entry to Weblogic pointing to the configuration folder. You can do that in the setDomainEnv.sh or for Managed Servers, in their configuration (web console), server start, classpath.
