About the Cognos Framework report oracle.jdbc.driver.T4CPreparedStatement Error

This is the question of a group of friends who were in the technology Group one day ago.

Said Cognos Framework test data error

Specific as

Specific error message

Oracle.jdbc.driver.T4CPreparedStatement.getParameterMetaData () ljava/sql/parametermetadate;

Baidu a bit, can not find any useful information ~ ~ ~

More and more are proposed, but there seems to be no specific solution to the scheme

Then i changed google, searched, in some people's blog to see relatively useful information

The author of that blog is the Oracle.jdbc.driver.T4CPreparedStatement.getParameterMetaData () that occurs when the Java Development Connection database is in progress ....

And he caused this mistake because of the introduction of a few Oracle driver package, his project has Class12.jar,ojdbc14.jar,ojdbc5.jar ... (I also look drunk)

So he removed the extra jar package, and the other one, it solved the problem.

I'm also trying to talk to a group of tech groups to see if there are multiple driver packages

Eventually...

Problem solved, he said his driver bag is damaged, in exchange for a new one is no problem ~!!!

Although not many driver packets caused by the error, but also with the driver package related bar ~ ~ ~

A friend of this situation can also try

After the Bo ~ ~ ~
