Enable larger file uploads via Tomcat manager

Shortly after I automated code deployments in my Tomcat7 development testing environment, I found that some larger builds began failing with the following error:


org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (...) exceeds the configured maximum (62428800)

After a little digging, I found that the WAR files were exceeding the default maximum upload size, thankfully, this is trivial to increase.


sudo vi /usr/share/tomcat7-admin/manager/WEB-INF/web.xml

(Change 52428800 to a larger number, perhaps doubled like 104857600)

<multipart-config
<!-- 50MB max = 52428800 (100MB = 104857600) -->
<max-file-size>104857600</max-file-size>
<max-request-size>104857600</max-request-size>
<file-size-threshold>0</file-size-threshold>
</multipart-config>

  1. I too would be interested in learning how the Debian community recommends updating this value, as the web.xml in the “manager” application for Tomcat would need to be modified.
