It provides a "pure Java" HTTP web server environment in which Java code can also run. Thus it is a Java web application server, although not a full JEE application server.
Apache Tika - a content analysis toolkit The Apache Tika™ toolkit detects and extracts metadata and text from over a thousand different file types (such as PPT, XLS, and PDF). All of these file types can be parsed through a single interface, making Tika useful for search engine indexing, content analysis,...
The Apache HTTP Server Project is an effort to develop and maintain an open-source HTTP server for modern operating systems including UNIX and Windows.

This can be done by commenting out the `LoadModule xml2enc_module modules/mod_xml2enc.so` directive in the Apache HTTP Server configuration. A service restart is required for the change to take effect.\n\n```bash\n# Edit the Apache configuration file, e.g., /etc/httpd/conf.modules.d/00-base.conf\n# Comment out the line:\n# LoadModule xml2enc_module modules/mod_xml2enc.so\n\n# Reload the httpd service\nsudo systemctl reload httpd\n```\n\n*Note: Disabling `mod_xml2enc` will cause any configurations relying heavily on `mod_proxy_html` or raw HTML/XML encoding conversions to function incorrectly or fail. Red Hat strongly recommends upgrading to a patched version of `httpd` as soon as it becomes available for your specific RHEL channel.*"

Title
Apache Tika: Arbitrary Local File Read in ISArchiveParser
Summary
Relative Path Traversal in the ISA-Tab parser in Apache Software Foundation Apache Tika from 1.8 through 3.3.1, and 4.0.0-alpha-1, allows an attacker who can place files in a directory that the application subsequently parses to read arbitrary files accessible to the Tika process and have their contents emitted into the extracted text output, via a "Study Assay File Name" value in the ISA-Tab investigation file that traverses outside the dataset directory. Users are recommended to upgrade to version 3.3.2 or 4.0.0-beta-1, which fixes this issue.
