Bug ID: 54971
Summary: javax.servlet.http.Part.write(String fileName) is not
properly implemented
Product: Tomcat 7
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org
Reporter: howeverk...@gmail.com
Classification: Unclassified
1. fileName parameter / relative vs absolute
filaName parameter specification in
<1><JSR-000315 Java Servlet 3.0 Final Release javadocs>
is different from the <2><javax API tomcat refers to>.
<1> <JSR-000315 Java Servlet 3.0 Final Release javadocs>
Parameters:fileName - the name of the file to which the stream will be written.
The file is created relative to the location as specified in the
MultipartConfig
<2> javax. API tomcat refers to
* @param fileName The location into which the uploaded part should be
* stored. Relative locations are relative to {@link
* javax.servlet.MultipartConfigElement#getLocation()}
Tomcat is implemented as specified in <2> so that it can process "absolute
path",
but it should only accept "relative path" as specified in <1>
<JSR-000315 Java Servlet 3.0 Final Release javadocs>
2.
If MultiPartConfig.location is not set,
write( String relative path ) throws FileNotFound Exception.
A default location needs to be set in order to avoid such exception.
example) os: windows8
part.write("/test");
