Sun[tm] ONE Web Server Samples
Using Oracle with the Samples

This document contain instructions on how to configure the Oracle JDBC driver with the Sun ONE Web Server. The samples included with the web server include instructions for configuring them to work with an Oracle database. You can use jdbc-simple as a template to configure Oracle to work with other applications. (For database-related information, see the Oracle documentation.) To learn about basic operations with Oracle and the Sun ONE Web Server, read the following sections:

## Configuration and Set Up Instructions Configure Sun ONE Web Server with Oracle Type 4 JDBC Driver You can add the Oracle JDBC driver to the web server classpath as described in this section. Open the server.xml file of the web server instance. Add the location of the Oracle driver in the classpathsuffix. For example, check the following sample JAVA element (with /oracle/jdbc/lin/classes12.jar as the <Oracle jdbc driver>):
    Change it from this:

    <JAVA javahome="/ws61/bin/https/jdk" serverclasspath="/ws61/bin/https/jar/webserv-rt.jar:
    ${java.home}/lib/tools.jar:/ws61/bin/https/jar/webserv-ext.jar:/ws61/bin/https/jar/webserv-jstl.jar:
    /ws61/bin/https/jar/ktsearch.jar" classpathsuffix="" envclasspathignored="on" debug="false"
    debugoptions="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n" dynamicreloadinterval="2">
    ........
    ........
    </JAVA>

    to this:

    <JAVA javahome="/ws61/bin/https/jdk" serverclasspath="/ws61/bin/https/jar/webserv-rt.jar:${java.home}/lib/tools.jar:
    /ws61/bin/https/jar/webserv-ext.jar:/ws61/bin/https/jar/webserv-jstl.jar:
    /ws61/bin/https/jar/ktsearch.jar" classpathsuffix="/oracle/jdbc/lin/classes12.jar"
    envclasspathignored="on" debug="false"
    debugoptions="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n" dynamicreloadinterval="2">
    ........
    ........
    </JAVA>
NOTE: The web server must be restarted to update the classpath. If you are using a Type 2 driver, you must also add <oracle_home>/lib to the nativelibrarypathprefix . Create the Database Users and Schemas for the Sample Application The following steps assume that you have access to a running Oracle RDBMS. Note that the user creation script will drop any existing users with the same name. Use <install_root>/plugins/java/samples/webapps/docs/cr_ora_user.sql to create a specific sample Oracle user. This script will create the user on the specified tablespace. For example, using sqlplus login as system/manager: <SQL> @cr_ora_user.sql user_name password tablespace_name NOTE: tablespace_name If you want to create a separate tablespace for all samples, you can use the <install_root>/plugins/java/samples/webapps/docs/cr_ora_tb.sql script. If you don't want to create the new tablespace, you can use the sql command "select tablespace_name, status from DBA_TABLESPACES" to see the available online tablespaces (run this sql command as system/manager). You can use sqlplus to execute SQL statements found in the .sql files within the src/sql directory of each JDBC-relevant sample. NOTE: If only one .sql file exists in the src/sql directory, then it will work with both Oracle and PointBase. For example, here are the detailed steps for configuring the jdbc-simple sample to work with Oracle: (a) Use sqplus and login as system/manager to create oracle user jdbc/jdbc on the specified tablespace. <SQL> @cr_ora_user.sql jdbc tablespace_name (b) Load the schema for the jdbc-simple application as the user 'jdbc' by using the script jdbc-simple-ora.sql located in <install_root>/plugins/java/samples/webapps/jdbc/simple/src/sql. <SQL> @jdbc-simple-ora.sql (c) Run the application (refer to jdbc simple sample). (d) In the same way, you can use the same 'jdbc' user for all of the samples, or you can create a different user for every sample. ## ## Registering JDBC Resources and Defining Connection Pools You can reveiw the sample common.xml and build.xml files to learn how to use the ant to define JDBC resources and connection pools. Also refer to the following: (1) Using Ant with the Samples (2) Deploying Samples and Creating the Resources using Admin GUI ## Troubleshooting and Notes JDBC/Blob Sample: If the Type 4 JDBC driver is used as explained in this document, the uploaded file cannot exceed 5 KB. The workaround is to use the Type 2 OCI driver. Here are the steps to set up the driver: 1. In the administrative console, modify the property for connection pool jdbc-blobPool. The value of the url property should be: jdbc:oracle:oci8@db_alias (db_alias should be defined in TNS). 2. Add the path of the driver to the classpathsuffix in server.xml. 3. Restart the web server.
