Migrating from JBoss to TomEE. CMT are not woking at all

I am new to TomEE. I am trying to migrate from JBoss 4.2.3 GA to TomEE PLus 1.7.1. I have developed all my EJBs using EJB 2.0 spec. All EJB are Statekess session beans. I have a few EJBs as BMT and are working fine. But CMT EJBs are not working at all.

tomee.xml

<Resource id="TPDDS" type="DataSource">    
JdbcDriver=com.jnetdirect.jsql.JSQLDriver
JdbcUrl=jdbc:JSQLConnect://dbamigratedb/database=shoppingcart/ssl=mandatory
UserName=prao
Password=pass
jtaManaged=true
validationQuery=select 1 from account
maxWaitTime=30000
maxActive=100
testOnBorrow=true
</Resource>

<TransactionManager id="myTransactionManager" type="TransactionManager">
adler32Checksum = true
bufferSizeKb = 32
checksumEnabled = true
defaultTransactionTimeout = 10 minutes
flushSleepTime = 50 Milliseconds
logFileDir = txlog
logFileExt = log
logFileName = howl
maxBlocksPerFile = -1
maxBuffers = 0
maxLogFiles = 2
minBuffers = 4
threadsWaitingForceThreshold = -1
txRecovery = false
</TransactionManager>

The Exception I get is:
