I'm trying to have my project's Strings/ messages stored in an external .properties file. I think I have everything wired up OK, but still I get:
org.springframework.context.NoSuchMessageException: No message found under code 'subtype.user.client' for locale 'null'.
Whenever I try:
String string = messageSource.getMessage("subtype.user.client", null, null);
My spring xml config files are as follows. Since the project is really big with lots of beans, I have different spring xml config files defining different types of beans, and a main spring.config.xml file that wires them all together.
Messages file named messages.subtypes
subtype.user.user=User
subtype.user.client=Client props
subtype.user.staff=Staff
subtype.user.clerk=Clerk
subtype.user.secretary=Secretary
Messages beans file called spring.messages.config.xml

You get this error because you pass the Locale parameter as null. Try
String string = messageSource.getMessage("subtype.user.client", null, Locale.ENGLISH);
Even though you have not defined a file messages.subtypes_en.properties defined it should fall back to messages.subtypes.properties
A couple of things come to mind looking at your code any of which might cause the problem:
Your xml config name contains "." as separators. This is against conventions. Consider renaming your config file to spring-messages-config.xml
Your language properties file has no properties suffix, again convention suggests to name this file messages-subtypes.properties
In both your application context xml files you define a bean named messageSource. Consider deleting one of them.
My prime suspicion as to why your code does not work lies with the way you define basename on ReloadableResourceBundleMessageSource. Looking at the JavaDoc for setBasename method there is some form of convention of configuration at work:
Set a single basename, following the basic ResourceBundle convention of not specifying file extension or language codes, but in contrast to {#link ResourceBundleMessageSource} referring to a Spring resource location: e.g. "WEB-INF/messages" for "WEB-INF/messages.properties", "WEB-INF/messages_en.properties", etc. XML properties files are also supported: .g. "WEB-INF/messages" will find and load "WEB-INF/messages.xml", "WEB-INF/messages_en.xml", etc as well.
This suggests that once you have renamed your message properties file to messages-subtypes.properties, you should change your config to <value>classpath:messages-subtypes</value>, make sure that the file is in the classpath and everything should start working.
Try renaming the messages.subtypes file to messages.subtypes.properties.

Previously I had only one project named "projectA".
I have a XML bean configuration file "service.xml" in "projectA" with bean of class "com.home.karoom.impl.adapter"
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<bean id="<bean id="espAdapter" class="com.home.karoom.impl.adapter">
<property name="writer" ref="writer" />
</bean>
</beans>
Now, I created new project called "projectB" and moved the bean-class "com.home.karoom.impl.adapter" to "projectB".
Now, the bean-class "com.home.karoom.impl.adapter" doesn't exist anymore in "projectA"
How ca I refer to the new class location in "projectB" using "service.xml" ?
I think you have to import the file into your project
<import resource="classpath:spring-config.xml" />
here is a good explanation on how to share code/class between projects.
Short answer is, your class com.home.karoom.impl.adapter should be put in separate project and package as a jar. Then added as dependency to your projects (A and B).
Be sure to follow convention and name your classes starting with capital letter
I have a problem with Environment env.getproperty, env not find local properties, but it find system properties. I dont know about this so much and I need to solve it. Please, help me.
Attached my code and its configuration.

property-placeholder does not place properties into env. It is for variables set on OS level.
better use System.getProperty("property_name") which includes env, JVM properties, -D properties passed into java command line and yes - those from property-placeholder.
Also you may consider to use your url as bean property and do not get it explicitly, but by spring bean property definition like ${url.services.search}
instead of having property name in code. After time it may hard to find where what property loaded. It is better approach...
I'm trying to set up a local overrides file for some of my bean definitions. Yes, it's a fragile system, but it's just for testing. Basically, I've got one XML file which looks more or less like:
<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!-- so many beaaaannzzz -->
<utils:list id="partnerList" value-type="my.partner.Class">
<ref bean="previouslyDefinedBean"/>
</utils:list>
<!-- include local bean definition overrides -->
<import resource="file://${user.home}/somedirectory/prefix-*.xml"/>
</beans>
This works in general, but it has an unexpected and undesirable result with the utils:list element.
My somedirectory/prefix-*.xml override file defines another list:
<utils:list id="partnerList" value-type="my.partner.class">
<ref bean="otherBean"/>
</utils:list>
When it is picked up however, I get an undesired result: partnerList has two beans in it, previouslyDefinedBean and otherBean, while I want it to only have the latter.
Now, I'm aware Spring offers some weird weird collection merging, so I tried setting <utils:list merge="false"... but that blew up as an unsupported attribute. Is there something I can do to continue using this override system for the util:list, or have I got to take another tack entirely?
It is useful to have different property sets for different users.

<context:property-placeholder
location="classpath:/path/to/package/default.properties,
classpath:/path/to/package/#{ systemProperties['user.name'] }.properties"/>
</beans>
When executing the application, spring does not recognize the expression. The context does not start and spring says: class path resource [path/to/package/#{ systemProperties['user.name'] }.properties] cannot be opened
When I replace the expression manually with a string resulting in a valid resource then the behaviour is as expected. The manual states it should work.
The spring-context and spring-core (3.1.2-RELEASE) are in classpath.
How come spring does not pick up the environment variable?
I'm open to alternate solutions solving the same functional problem.
SpEL expressions are not allowed there; you can do what you want indirectly, though...
<context:property-placeholder properties-ref="props"/>
<util:properties id="props" location="classpath:#{systemProperties['foo']}"/>
Here is the complete answer to the question. Keeping the override of user properties over default properties. My edit of the accepted answer got rejected.
<context:property-placeholder properties-ref="springContextCongifurationProperties"
location="classpath:/path/to/package/default.properties"
local-override="true"/>
<util:properties id="springContextCongifurationProperties"
location="classpath:/path/to/package/#{ systemProperties['user.name'] }.properties"/>
Is there a special way for doing this?
What i got is:
config.properties with param.key=value
web.xml with ContextLoaderListener that reads the configuration
pages-servlet.xml that defines servlet beans.
What I want is to configure one of the beans in pages-servlet.xml with param.key.
I'm using <property name="myField" value="${param.key}"/> in the xml but I see that the field is configured with ${param.key} instead of 'value'.
What is the right way to configure the bean?
Ok, I solved it by importing application context file that defines configuration bean into pages-servlet.xml.
It works, but seems very wrong.
Property placeholder is what you want.
