更改上游项目中的速度日志文件位置

Question

I have a Java web application that uses a library that initializes/configures Velocity.

We're migrating this project from WebLogic to Tomcat.

The application now throws errors, traced to Velocity. When Velocity is initialized, the default location for the log file is in a directory which the application doesn't have permissions to write to, thus Velocity is never initialized.

I tried to create a velocity.properties file in the upstream project in my WEB-INF/classes directory (mirroring the folder structure of the Velocity jar file itself), but this doesn't seem to have changed anything. Velocity is still failing to initialize.

Does anyone know of a way to accomplish what I'm describing? I don't want to touch the library which is initializing Velocity–I'd rather just override the log file location in the upstream project.

Answer 1

In your WEB-INF directory look at web.xml and look for <param-name>configURI</param-name> and it's <param-value> that follows.

For example my web.xml has this

<init-param>
    <param-name>configURI</param-name>
    <param-value>WEB-INF/scripts</param-value>
</init-param>

In my WEB-INF/scripts is where my velocity.properties file is

This is the property in velocity.properties that controls the log file location

runtime.log =

Which specifies the full path to my velocity.log

Mine looks like this

runtime.log =/var/log/velocity.log
