Problem Description: How do you configure jconnect JDBC Connection Pooling with apache tomcat 4.1.x?

Tip or Workaround: (Observations Performed with jconnect-5_2 and tomcat 4.1.18)

In line, below, area the text of what sales:

Web.xmlsybase.jspserver.xml.sybasedelta

Please proceed as stock:

1) Create The Following Folders: 1.1) C: / Program Files / Apache Group / Tomcat 4.1 / WebApps / Sybase1.2) C: / Program Files / Apache Group / Tomcat 4.1 / WebApps / Sybase / JSP1.3) C: / Program files / apache group / tomcat 4.1 / WebApps / Sybase / Web-INF1.4) C: / Program Files / Apache Group / Tomcat 4.1 / WebApps / Sybase / WEB-INF / JSP

2) Move the file "Web.xml" to folderc: / program files / apache group / tomcat 4.1 / webapps / sybase / web-inf

3) Move the file "sybase.jsp" to folderc: / program files / apache group / tomcat 4.1 / webapps / sybase / jsp

4) Copy the contents of file "server.xml.sybasedelta" INTO YOUREXISTING "C: / Program Files / Apache Group / Tomcat 4.1 / conf / server.xml" file.

Insert the new content as an additional context within the "Tomcat-Standalone" service specification. Insert this after the last "" entry, but before the "" terminatorin the "Tomcat-Standalone" service grouping.

Replace The Following Strings with Values ​​Appropriatto your installation:

Database_hostnameYour_dbnameYour_UserIDYOUR_PASSWORD

IF Your DataServer Is Not "Listening" on Port 5000, Make The Corresponding Change for the Port, TOO, IN Theconnection URL.

5) Copy Your Jconnect / Classes / JCONN2.JAR File Into Directoryc: / Program Files / Apache Group / Tomcat 4.1 / Common / LIB

6) SHUTDOWN AND RESTART TOMCAT.

7) from your Web Browser, Enter the Following URL:

Http: // localhost: 8080 / Sybase
