| <p> |
| <b>NOTE:</b> DBCP v1.2.1 requires Pool v1.2, make sure you use the correct version! |
| </p> |
| |
| <hr/> |
| <p>DBCP 1.2.1 is a maintenance release to restore full JDK 1.3 compatibility.</p> |
| <p>The problem lies in the improper use of a JDK 1.4 method: java.lang.Boolean.valueOf(boolean)</p> |
| <p>This method was used in the defaultReadOnly property processing.</p> |
| <p>We recommend to upgrade to DBCP 1.2.1 to avoid this problem altogether.</p> |
| <hr/> |
| |
| <p>If you use the defaultReadOnly property in a JRE <1.4, you will get the following error: |
| <source> |
| java.lang.NoSuchMethodError |
| at org.apache.commons.dbcp.BasicDataSource.setDefaultReadOnly(BasicDataSource.java:75) |
| at org.apache.commons.dbcp.BasicDataSourceFactory.createDataSource(BasicDataSourceFactory.java:162) |
| at org.apache.commons.dbcp.BasicDataSourceFactory.getObjectInstance(BasicDataSourceFactory.java:144) |
| at org.apache.naming.factory.ResourceFactory.getObjectInstance(ResourceFactory.java:176) |
| </source> |
| </p> |
| |
| <p>The simple workaround is not to use this property. For example remove the following from the tomcat config.xml. |
| <source><![CDATA[ |
| <parameter> |
| <name>defaultReadOnly</name> |
| <value>true</value> |
| </parameter> |
| ]]></source> |
