Dear Fellow OpenMeetings Users and Maxim:
This issue resulted from a previous thread “File Upload to File
Explorer"
(https://www.mail-archive.com/dev@openmeetings.apache.org/msg03057.html).
After eliminating more than 15 potential causes, we have now found the
root cause of the File Upload to File Explorer error that we have been
facing for the past two months. Hence, for focus, we are starting this
new thread on the root cause of the issue.
*Details***
*Problem*
There are two instances of OpenMeetings running in the following two
server environments:
Server 1 (CentOS 6.5, MySQL, DBCP, Java JDK 7u 31)
Server 2 (CentOS 7, MariaDB, DBCP2, Java JDK 7u 67)
OM works perfectly in Server 1. Further, when we compile OM in Server 1
(CentOS 6.5) and install it in Server 2 (CentOS 7) , OM works perfectly.
However, when we compile and install the same source code in Server 2,
it gives: The service cannot be found for the endpoint reference
(EPR). When we type URL:
http://ourserver:5080/CoscendCC/services/FileService?wsdl, it gives an
error of HTTP Status 500.
Further, we get the same error output for every service we type in URL
(RoomService, CalendarService, JabberService, UserService,
ServerService). However, some services are working perfectly, while
others are not.
Red5.log
ERROR o.a.c.c.C.[.[.1.1.5.[.[jsp] - Servlet.service() for servlet jsp
threw exception javax.servlet.ServletException: File
"/axis2-web/listSingleService.jsp" not found
We contacted Axis2 project team. They suggested the potential
causes to be:
·The Red5 server that is making RPC calls is not able to locate
[openmeetings-3.0.4-RELEASE.aar] file in the deployment folder.
·The [openmeetings-3.0.4-RELEASE.aar] may have an error, if it is in
the right deployment folder.
*Seeking Guidance.*
1. We have checked the services directory contains the required AAR file.
<prefix>/dist/red5/webapps/<application-context>/WEB-INF/services
2. There is a step in the post-compile installation, where we set entire
production directory hierarchy to "nobody" user.
chown -R nobody <OpenMeetings installation directory>.
Would this be affected (need to be modified) by any changes in
Centos 7,
and, would it be more critical/strict in Centos-7 about this?
3. Should we set up logging parameter to go deeper into the root cause?
Where and what values are advised for this issue?
Should we use <prefix>\main\webapp\WEB-INF\classes\logback-config.xml?
It has numerous loggers set to ERROR. Should we set the Axis2 logger
to "DEBUG", and re-compile ?
Which Log File is to be checked after this?
* <logger name="org.apache.axis2" level="ERROR" />*
<logger name="com.mchange.v2" level="ERROR" />
<logger name="org.apache.axiom" level="ERROR" />
<logger name="org.apache.commons.httpclient" level="ERROR" />
<logger name="de.hunsicker.jalopy.io" level="ERROR" />
<logger name="org.apache.axis2.enterprise" level="ERROR" />
<logger name="httpclient.wire.header" level="ERROR" />
<logger name="org.apache.directory" level="INFO" />
<logger name="org.apache.mina.filter.ssl.SslFilter" level="ERROR" />
<root level="DEBUG">
<appender-ref ref="FLOG2" />
<appender-ref ref="CONSOLE2" />
</root>
OR, any other file for logging?
4. For a test, is there a correct way to explode the hierarchy of files
and copy it to the ".../webapps/<application-context>/WEB-INF/services"
directory? Does it require any additional change to work like this?
5. Is there anything else we should check ?
Thank you.
