Hi Massimo,

It might cause due to Java Runtime are not properly found in the sever.

Please check the JAVA_HOME system enviromental variable in my computer (My computer > Priperties >> Advance >> Startup and Recovery >> Enviromental Variable >> System Variables >> Add new JAVA_HOME parameter with path for installed Java JDK)

And Update your server IP address and host name in host file entry at (RUN > drivers > etc > host file)

Hope it helps

Hi Arun,

Thanks for help, i have check JAVA_HOME system enviromental variable and is ok.

After installation of SP 16 7.0 i have Runtime Error in irj, i have found this step to resolve it :

I have rename this file :

1- com.sap.portal.navigation.api_service.par.bak

2- com.sap.portal.navigation.service.par.bak

remove .pak and I copy its under

usr\sap\<SID>\JCXX\j2ee\cluster\serverX\apps\sap.com\irj\servlet_jsp\irj\root\WEB-INF\deployment\

later I restated sap and java.

after I had new problem javax.servlet.UnavailableException: Initialization of Dispatcher failed.

Any help?

Thanks

Hi Massimo,

Have you modified par file

>1- com.sap.portal.navigation.api_service.par.bak

>2- com.sap.portal.navigation.service.par.bak

If so, then there is problem on it...Becuase those PAR files are also stored in the work directory.

I would suggest, please take a backup of those PAR file from Deployment and Work Directory and deploy it again from NWDS.

Hope it helps

I have re-install SP and my problem is solved.

Maybe it was a mismatch problem of packages versions
