--------------------------
Summary: Specifying log4jConfiguration in web.xml fails on Windows
when the file's path contains spaces
Key: LOG4J2-888
URL: https://issues.apache.org/jira/browse/LOG4J2-888
Project: Log4j 2
Issue Type: Bug
Affects Versions: 2.1
Environment: Windows 7, Apache Tomcat 7, Java 7
Reporter: Kim
Priority: Minor
When specifying the context parameter log4jConfiguration in the web.xml of a
web application and the resulting string contains spaces, e.g.
{code:xml}
<context-param>
<param-name>log4jConfiguration</param-name>
<param-value>file:///${sys:catalina.base}/conf/logtestapp-log4j.xml</param-value>
</context-param>
{code}
the following exception is thrown on Windows systems:
{code}
ERROR StatusLogger Unable to convert configuration location [file:///C:\Program
Files\Apache Software
Foundation\apache-tomcat-7.0.54/conf/logtestapp-log4j.xml] to a URI
java.net.URISyntaxException: Illegal character in path at index 18:
file:///C:/Program Files/Apache Software
Foundation/apache-tomcat-7.0.54/conf/logtestapp-log4j.xml

{code}
Substituting spaces with %20 seems to solve the problem:
{code:xml}
<context-param>
<param-name>log4jConfiguration</param-name>
<param-value>file:///C:/Program%20Files/Apache%20Software%20Foundation/apache-tomcat-7.0.54/conf/logtestapp-log4j.xml</param-value>
</context-param>
{code}
but this will require using fixed strings instead of lookup values.
Note: This bug appears to be very similar to LOG4J2-409.
