Examine your settings to make sure they are correct. Make sure you can connect with the same settings on your machine. But connections are present in database. The settings are correct, because I can acces database from xsp ... esql:connection esql:driveroracle.jdbc.driver.OracleDriver/esql:driver And so on. Can anybody help me, please ?

I have tested the database connection code under JDK 1.4, though I admit that I did not test it against the Oracle database. It is *possible* that the Oracle driver does not work under JDK 1.4, though if you used the old style ESQL values and got things working I suspect it is the fact that the pooling code needed to be recompiled.
