With the patch 6.6.0.29 SAP upgraded Tomcat version to 7.0.100. Unfortunately, this breaks backoffice with the exception in your question.

To fix this error, follow the following steps:

1. Stop the server if it’s running.
2. Download jasper-el.jar from Apache 7.0.99. The file is located under lib folder of Tomcat. (You can download Apache 7.0.99 from https://archive.apache.org/dist/tomcat/tomcat-7/v7.0.99/bin)
3. Replace the file with the one under ${HYBRIS_BIN_DIR}/platform/tomcat/lib
4. Start the server

P.S. You can place this jar file into customize folder, to store this jar in your code repository and every developer can fix this issue on their local easily with ant customize command.

Hope this helps,

After implementing the above changes another error is coming during the server start up due to which backffice is not opening:

The error is:
