Adding a directory to tomcat classpath and read the property file in spring

问题

I am trying to read the test1.properties file which is located at an external folder.

here is my spring config file:

<bean id="propertyConfigurer3" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="ignoreUnresolvablePlaceholders" value="true"/>
    <property name="locations">
        <list>
            <value>classpath:test.properties</value>
            <value>classpath:test1.properties</value>
        </list>
    </property>
</bean>

if I place the test1.properties in the tomcat7/lib folder, I am able to read it. However, I want to place it in a different directory as tomcat7/env/test1.properties

I have added the path to the the conf/catalina.properties:

common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar,${catalina.home}/env

This its not working, please help

solution: Ok.. finally fixed it.. I had been doing it correctly this whole time.. it was my IDE which caused the problem. The IDE was not picking up the changes in the catalina.properties file. I had to delete the server config in my IDE and re configure it.

Use setenv.sh in the bin directory. If the file doesn't exist, create it. To add something to the classpath use the following syntax:

CLASSPATH=/yourdir/

For windows: setenv.bat

Solution: creating the setenv.bat file under tomcat bin folder helped me in WINDOWS.

If your intention to keep file outside the war or ear , so that you can update it without compling and creating war again. just editing the file and restarting the server. Keep it in any external folder , even outside server and give absolute path in spring.

<bean id="propertyConfigurer3" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="ignoreUnresolvablePlaceholders" value="true"/>
<property name="locations">
    <list>
        <value>classpath:test.properties</value>
        <value>**file:/someexteranal/dir/test1.properties**</value>
    </list>
</property>

Best thing , you can give this / path with root in Unix/linux and same will work in windows, just need to keep file in directory where your server is installed. Like your tomcat in D drive , then keep it in D:\someexternal\dir and above code will work fine there too
