WSO2 ESB: Getting Dead Pages When Running in Windows Service

0
votes

I'm getting blank pages when navigating the WSO2 ESB-4.9.0 management console. For example, the registry, templates, endpoints, and local entries pages are all blank when navigating to them in the console UI.

I've found the following errors in the logs:

  • Error during rendering

  • IO Error executing tag: JSPException while including path '/templates/list_templates.jsp'. ServletException while including page.

The ESB is running in a YAJSW Windows Service. I should note that the ESB runs fine when running straight from the command line, it's just when using the service wrapper.

Since you mentioned that the ESB starts as a window service, in carbon 4.4.x, default wrapper.conf file needs to be updated with following additional entries.

wrapper.java.additional.26 = -Dwso2.carbon.xml=${carbon_home}\\repository\\conf\\carbon.xml
wrapper.java.additional.27 = -Dwso2.registry.xml=${carbon_home}\\repository\\conf\\registry.xml
wrapper.java.additional.28 = -Dwso2.user.mgt.xml=${carbon_home}\\repository\\conf\\user-mgt.xml
wrapper.java.additional.29 = -Dwso2.transports.xml=${carbon_home}\\repository\\conf\\mgt-transports.xml
wrapper.java.additional.31 = -Dorg.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false
wrapper.java.additional.33 = -Dfile.encoding=UTF8

You can verify these configurations in wrapper.conf and these configurations may help you to solve the jsp error.

I just used the NSSM - the "Non-Sucking Service Manager".

It's actually amazingly simple to install a Service using this tool. https://nssm.cc

Just set it up to point at the wso2server.bat file

Keeping an eye on this issue however: https://wso2.org/jira/browse/ESBJAVA-4342
