Servlet Connection Pooling for Dummies
By Geertjan-Oracle on Apr 04, 2005
- After deploying, as described in the previous blog entry ("Super Cool Connection Pool"), right-click the index.jsp file and choose View Servlet.

- Create a servlet named index_jsp and put it in a package called org.apache.jsp. (Right-click the project node, choose New > Servlet.)
- Paste the code you copied over all the default code in the template.
- Right-click the Libraries node, choose Add Library, click Manage Libraries, click New Library, name it JASPER, click Add JAR/Folder, browse to enterprise1\\jakarta-tomcat-5.5.7\\common\\lib and select jasper-runtime.jar. Click OK.
