caused by:java.io.filenotfoundexception:attachment/upload__58686996_15b664f6902__8000_00000005.tmp (without that file or directory)
At Java.io.FileOutputStream.open (Native Method)

...

Root Cause:

Struts-main.xml specify where to save the uploaded file:

<constant name= "Struts.multipart.saveDir" value= "attachment"/>

Then the attachment folder will be created in the User.dir location, User.dir for the Tomcat startup.sh to start the working directory, generally tomcat/bin directory;

However, if the current directory at/xxx/tomcat/bin/startup.sh startup is the root directory/, and the Tomcat startup user does not have permission to create a directory in the/directory, uploading the file will fail with an error as above.

Solution:

1. Switch the working directory when Tomcat starts

2. Make sure that the attachment directory can be created in any directory launched by Tomcat
