如何在web.xml中访问环境变量

Question

How can i set the context param-value with an environment variable in web.xml?

I tried to do it like below, but it didn't work

<context-param>
  <param-name>testName</param-name>
  <param-value>${TEST_HOME}</param-value>
</context-param>

Where $TEST_HOME will be an environment variable.

is there any way to put external variables in web.xml ?

You may try like this:

<env-entry>
    <env-entry-name>Name</env-entry-name>
    <env-entry-type>java.lang.String</env-entry-type>
    <env-entry-value>value</env-entry-value>
</env-entry>
