<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>
