Hello All,
We are using EH&S Web interface to display the generated SDS on the web.
We were required to restart the web interface server due to some issue.
However, after the restart, the links to web interface servers are not working.
We are getting java dump which is as mentioned below:
type Exception report

note The full stack trace of the root cause is available in the Apache Tomcat/7.0.8 logs.
Can anyone please guide here.?
We have tried a lot to solve this error at our end, but we could not resolve this error.

Hello Raphael, Hello Christoph,
Thank you for your inputs.
To give you a brief about our solution in place:
We are using Tomcat Application to host the web interface. The SDS are generated at ECC end. We have separate web interface servers to host this application.
SDS generated at SAP end, are available on the website of our customer via this web interface.
We dont have PLM in our case. The SDS are generated at SAP end via WWI server, Stored/Kept via DMS and then displayed on Website.
Things were working fine and customers were able to get the SDS via website until we restarted the web interface server.
After restart of one of our web interface server we are getting this error - Could not initialize class com.sap.mw.jco.JCO
As Raphael has suggested that there should be some problem with Java connector.
Can you guide me on how to check JCO configuration in Apache.?
What all things I can check in order to verify JCO configuration.?
Our version would also be quite old so is it possible to upgrade it.?
Thank you again for your help.
Best Regards,
Aarohi
Hi Aarohi,
I have checked the mentioned errors and it doesn't seem to be an error with Web interface application but an issue with JCO connector used.
Since this is not an EHS problem it's hard for me to give a precise help, but could say that you should check your JCO configuration in Apache.
For this you could use as source of information following notes:
1274700 - SAP Role Import error: com/sap/mw/jco/JCO$Function
https://css.wdf.sap.corp/sap/support/notes/1274700
and
1292144 - JCO error when Importing SAP Roles in CMC
https://css.wdf.sap.corp/sap/support/notes/1292144
Hope this can help you, if not i suggest you to check for JCO foruns also.
Best regards,
Raphael
