STATELESS
Declarable in tomee.xml via
Declarable in properties via
Foo = new://Container?type=STATELESS
Supports the following properties
Property Name
Description
TimeOut
Specifies the time to wait between invocations. This value is measured in milliseconds. A value of 5 would result in a time-out of 5 milliseconds between invocations. A value of zero would mean no timeout. Default value is 0.
PoolSize
Specifies the size of the bean pools for this stateless SessionBean container. Default value is 10.
StrictPooling
StrictPooling tells the container what to do when the pool reaches it’s maximum size and there are incoming requests that need instances. With strict pooling, requests will have to wait for instances to become available. The pool size will never grow beyond the the set PoolSize value. Without strict pooling, the container will create temporary instances to meet demand. The instances will last for just one method invocation and then are removed. Default value is true.
STATEFUL
Declarable in tomee.xml via
Declarable in properties via
Foo = new://Container?type=STATEFUL
Supports the following properties
Property Name
Description
Passivator
The passivator is responsible for writing beans to disk at passivation time. Different passivators can be used by setting this property to the fully qualified class name of the PassivationStrategy implementation. The passivator is not responsible for invoking any callbacks or other processing, its only responsibly is to write the bean state to disk. Known implementations: org.apache.openejb.core.stateful.RAFPassivater org.apache.openejb.core.stateful.SimplePassivater Default value is org.apache.openejb.core.stateful.SimplePassivater.
TimeOut
Specifies the time to wait between invocations. This value is measured in minutes. A value of 5 would result in a time-out of 5 minutes between invocations. A value of zero would mean no timeout. Default value is 20.
PoolSize
Specifies the size of the bean pools for this stateful SessionBean container. Default value is 1000.

Declarable in properties via
Foo = new://Resource?type=javax.sql.DataSource
Supports the following properties
Property Name
Description
JtaManaged
Determines wether or not this data source should be JTA managed or user managed. If set to 'true' it will automatically be enrolled in any ongoing transactions. Calling begin/commit/rollback or setAutoCommit on the datasource or connection will not be allowed. If you need to perform these functions yourself, set JtaManaged to 'false' In terms of JPA persistence.xml: "JtaManaged=true" can be used as a 'jta-data-source' "JtaManaged=false" can be used as a 'non-jta-data-source' Default value is true.
JdbcDriver
Driver class name Default value is org.hsqldb.jdbcDriver.
JdbcUrl
Url for creating connections Default value is jdbc:hsqldb:file:data/hsqldb/hsqldb.
UserName
Default user name Default value is sa.
Password
Default password
ConnectionProperties
The connection properties that will be sent to the JDBC driver when establishing new connections Format of the string must be [propertyName=property;]* NOTE - The "user" and "password" properties will be passed explicitly, so they do not need to be included here.
DefaultAutoCommit
The default auto-commit state of new connections Default value is true.
DefaultReadOnly
The default read-only state of new connections If not set then the setReadOnly method will not be called. (Some drivers don’t support read only mode, ex: Informix)
DefaultTransactionIsolation
The default TransactionIsolation state of new connections If not set then the setTransactionIsolation method will not be called. The allowed values for this property are: NONE READ_COMMITTED READ_UNCOMMITTED REPEATABLE_READ SERIALIZABLE Note: Most JDBC drivers do not support all isolation levels
InitialSize
The initial number of connections that are created when the pool is started Default value is 0.
MaxActive
The maximum number of active connections that can be allocated from this pool at the same time, or a negative number for no limit. Default value is 20.
MaxIdle
The maximum number of connections that can remain idle in the pool, without extra ones being released, or a negative number for no limit. Default value is 20.
MinIdle
The minimum number of connections that can remain idle in the pool, without extra ones being created, or zero to create none. Default value is 0.
MaxWait
The maximum number of milliseconds that the pool will wait (when there are no available connections) for a connection to be returned before throwing an exception, or -1 to wait indefinitely. Default value is -1.
ValidationQuery
The SQL query that will be used to validate connections from this pool before returning them to the caller. If specified, this query MUST be an SQL SELECT statement that returns at least one row.
TestOnBorrow
If true connections will be validated before being borrowed from the pool. If the validation fails, the connection is destroyed, and a new conection will be retrieved from the pool (and validated). NOTE - for a true value to have any effect, the ValidationQuery parameter must be set. Default value is true.
TestOnReturn
If true connections will be validated before being returned to the pool. If the validation fails, the connection is destroyed instead of being returned to the pool. NOTE - for a true value to have any effect, the ValidationQuery parameter must be set. Default value is false.
TestWhileIdle
If true connections will be validated by the idle connection evictor (if any). If the validation fails, the connection is destroyed and removed from the pool NOTE - for a true value to have any effect, the timeBetweenEvictionRunsMillis property must be a positive number and the ValidationQuery parameter must be set. Default value is false.
TimeBetweenEvictionRunsMillis
The number of milliseconds to sleep between runs of the idle connection evictor thread. When set to a negative number, no idle connection evictor thread will be run. Default value is -1.
NumTestsPerEvictionRun
The number of connectionss to examine during each run of the idle connection evictor thread (if any). Default value is 3.
MinEvictableIdleTimeMillis
The minimum amount of time a connection may sit idle in the pool before it is eligable for eviction by the idle connection evictor (if any). Default value is 1800000.
PoolPreparedStatements
If true, a statement pool is created for each Connection and PreparedStatements created by one of the following methods are pooled: public PreparedStatement prepareStatement(String sql); public PreparedStatement prepareStatement(String sql, int resultSetType, int resultSetConcurrency) Default value is false.
MaxOpenPreparedStatements
The maximum number of open statements that can be allocated from the statement pool at the same time, or zero for no limit. NOTE - Some drivers have limits on the number of open statements, so make sure there are some resources left for the other (non-prepared) statements. Default value is 0.
AccessToUnderlyingConnectionAllowed
If true the raw physical connection to the database can be accessed using the following construct: Connection conn = ds.getConnection(); Connection rawConn = ((DelegatingConnection) conn).getInnermostDelegate(); … conn.close() Default is false, because misbehaving programs can do harmfull things to the raw connection shuch as closing the raw connection or continuing to use the raw connection after it has been assigned to another logical connection. Be carefull and only use when you need direct access to driver specific extentions. NOTE: Do NOT close the underlying connection, only the original logical connection wrapper. Default value is false.
