liferay 6.0.6 のソース コードをコンパイルして jboss 5.1.0 GA にデプロイした後、jboss を起動すると次のエラーが発生しました。

Web でググったところ、c3p0 の問題に関連していることがわかりました。このリンクとこれを参照してください。指示に従って、構成の変更を試みます$LIFERAY_HOME/portal-ext.properties
hibernate.c3p0.max_statements=0
また
jdbc.default.acquireIncrement=5
jdbc.default.maxPoolSize=100
jdbc.default.minPoolSize=10
jdbc.default.numHelperThreads=10
しかし、うまくいきませんでした。
なにか提案を ？ありがとう
