Reading applicationContext file from META-INF in spring apps

[mozammil muzza]

Hi ALL,

I am trying to read applicationContext file from META-INF because i am creating the jar of my project APIs.
When i am trying to read it in my project(simple java project) normally e.g. in resource/applicationContext.xml then able to read it fine and loads successfully.
But once i create the lib of it and putting this spring context file in META-INF then its not reading the file...
i tried

ClassPathXMLApplicationContext("META-INF/applicationContext.xml")

and also

getClass().getClassLoader().getResourceAsStream("META-INF/applicationContext.xml")

.
But not able to create the bean, which i am able to read, load and create normally...

Please provide me proper solution of it.

Thanks...

Not sure I am following you. In your jar project you would put the config XML in src/main/resources. Then you are building that jar. Now you are including that jar as a dependency in another jar. Where is the META-INF stuff coming from? If both your projects have their own configs in src/main/resources and they have the same name i.e. applicationContext.xml you need to do something like this

ApplicationContext ctx = new ClassPathXmlApplicationContext("classpath*:applicationContext.xml");

This special prefix specifies that all classpath resources that match the given name must be obtained

Thanks 4 your reply Bill,

Actually when i am creating the archive(jar) of my classes (ofcourse it i'll have META-INF) at that time i am putting this config (xml etc.) file from /resource/.. to META-INF folder of the jar.
But but not able to read it from META-INF folder.

What I don't understand is why you are moving it. The classpath: prefix will look inside jars.

can you please tell me where exactly i have to use this...when i create the library of my apis or before i.e. when i am developing it in eclipse or will it work in both the scenarios ?

[Bill Gorder]

Should work in both.

You have in JAR1

src/main/resources/jar1-application-context.xml


You have in JAR2
src/main/resources/jar2-application-context-xml



Now JAR2 has a dependency on JAR1. JAR1 is on the classpath. When I start JAR2

ApplicationContext ctx = new ClassPathXmlApplicationContext("classpath:jar1-application-context.xml", "classpath:jar2-application-context.xml");

I tried this but not working, its giving exception on reading the file.

[Bill Gorder]

What kind of exception? If its a file not found then that means the jar is not on the classpath.

Form Apache Tomcat i think with default classpath point to "...webapp/WEB-INF/classes/" use debug mode.

So if you realy want file from folder "META-INF" try this.

InputStream is = Thread.currentThread().getContextClassLoader().getResourceAsStream( "../../META-INF/" + fileName);
