    I have installed openppm following the instructions.
    I have changed the setenv file.
    I have changed the startup file.
    I have data into the database.
    I am not using Tomcat as a Windows service.

    However when I try to access I receive the following error in the Login page:
    Login error
    Cannot open connection

    Hello?? Is anyone in here???

    Hi David,

    please make sure that you have installed Tomcat 6.0.35.

    You can download it from:http://archive.apache.org/dist/tomcat/tomcat-6/v6.0.35/bin/

    I had the same issue with XAMPP. Just corrected it overwriting the Tomcat folder (tomcat 7.0) from XAMPP with the downloaded Tomcat 6.0.35.

    I´m using XAMPP only for testing openppm at this moment, so I don´t know if this will cause problems with other web apps that you could be running in your XAMPP.

    I receive the following error in the Login page:
    Login error “Cannot open connection”

    Please, help!!

    As I can see in the screenshot it seems a very old release of OpenPPM as the last available release is 4.2.9.

    I’m not aware of SQLyog to be compatible with OpenPPM. Other database backends require jdbc connector to be installed in tomcat_folder/lib and reference it in tomcat_folder/conf/Catalina/localhost/openppm.xml.

    “jaas.config” is missing in apache-tomcat-7.0.29-deployer


    -rohini raj (05-04-2016)
