我已經安裝了SQL Workbench/J Build 118,我登錄了HSQL數據庫的Liferay Portal。java.sql.SQLException:無法從底層數據庫獲取連接! - HSQLDB
然後,我關閉了SQL Workbench而不對數據庫進行任何更改。 我重新啓動Liferay的Tomcat服務器,然後我得到了以下錯誤:
ERROR [localhost-startStop-1][DialectDetector:124] java.sql.SQLException:
Connections could not be acquired from the underlying database!
這個警告:
WARN [C3P0PooledConnectionPoolManager[identityToken->3c8jofUN]-HelperThread-#4][BasicResourcePool:1851]
com.mchange.v2.resourcepool.BasicResourcePool$ScatteredAcquireT[email protected] --
Acquisition Attempt Failed!!! Clearing pending acquires.
While trying to acquire a needed new resource, we failed to succeed more than
the maximum number of allowed acquisition attempts (3).
Last acquisition attempt exception:
java.sql.SQLException: error in script file line:

PS。我使用的是最新版本的HSQL JDBC驅動程序(v.2.3.3)
它正在工作。但爲什麼? – hutingung
