# Setting the Connection Pool Wait Timeout

In Business Components for Java, you can specify a Java VM parameter (-D) or jboserver.properties property that sets the amount of time the connection pool manager will wait for an available connection when one isn't immediately available. The default is 30 seconds.

#### To set the connection pool wait timeout:

When you start the business logic tier's Java VM, include the following directive on the command line:

    -Djbo.poolrequesttimeout=n

n is the amount of time, in milliseconds, from 0 to 2,147,483,647.

Alternatively, you can enter a line in the jboserver.properties file, which is stored in \lib\jbomt.zip:

    jbo.poolrequesttimeout=n

#### To set Java VM parameters through project properties:

1. In the Workspace view of the Navigator, right-click a business component project and choose Properties.

2. In the Run/Debug panel, type the parameters in the Java VM Parameters field.

3. Click OK.

   The values are added to the jboserver.properties file, which is stored in \lib\jbomt.zip.
