Error: ERR_INVALID_RESPONSE when exporting reports - Web Viewer 14.0

Products

• Output Management Web Viewer

Issue/Introduction

When attempting to use the export report option in Web Viewer 14.0, the browser returns the following error:

"This site Can't be reached
The webpage at http://###### might be temporarily down or it may have moved permanently to a new web address. 
ERR_INVALID_RESPONSE"

Environment

• Output Management Web Viewer 14.0
• CCS Apache Tomcat

Cause

The EXPORT_FORMAT OOXML creates a compressed file, which requires creating temporary directories and files in the location specified by the java.io.tmpdir directory.

The Tomcat started task user lacks write or directory creation (MKDIR) authority to this path.

The export request fails with:
CAHVS9000E Internal Server Error. HTTP status: 500 INTERNAL_SERVER_ERROR, Exception: java.lang.I
 llegalStateException, Error: java.nio.file.AccessDeniedException

Along with the following error from RACF:
ICH408I USER(SYSUSER ) - INSUFFICIENT AUTHORITY TO MKDIR

 

Resolution

Ensure the Tomcat started task user has sufficient permissions:

1. Give the Tomcat started task user (SYSUSER) read/write access to /###/tomcat10/temp directory 

Alternatively you can also:

2. Change the following line in CAHVCENV to point to a directory that the Tomcat started task user (SYSUSER) has read/write access.

IJO="$IJO -Djava.io.tmpdir=${CATALINA_BASE}/temp"
