This chapter describes the contents of errors when integrating ALTIBASE and TOMCAT.
No suitable driver
java.sql.SQLException: No suitable driver error occurs when the part corresponding to the Altibase of connection URL information is incorrectly entered.
Communication link failure
java.sql.SQLException: Communication link failure error occurs in the following situations:
1. When the ALTIBASE DB server is not running
2. When the ALTIBASE JDBC driver file is different from the version of the ALTIBASE DB server.
Ex) The version of the ALTIBASE DB server is 5.3.1, but when using the 5.1.1 version of the ALTIBASE JDBC driver file
3. When the connection URL information is set incorrectly
3-1. When the IP is set incorrectly
3-2. When the PORT_NO is set incorrectly
Ex) When the IP address of the ALTIBASE DB server is 10.10.10.10 and PORT_NO is 20300, but the IP address is set to 10.10.10.1 or PORT_NO is set to 20301.
Others
Occasionally, when a DataSource is specified in the context.xml file of a web application, it may be possible to encounter a client unable to establish a connection error or an error that the driver class is null even though the connection URL part is correct. In this case, delete the web application name.xml file in the $CATALINA_HOME/conf/catalina directory. Occasionally, even though the context.xml file of a web application has been changed, an error occurs because the file is not reloading.
