Select your database type
- First, Locate and copy the necessary jdbc driver for your database into <frevvo-home>\tomcat\lib.
- Edit the file <frevvo-home>\tomcat\conf\server.xml
- You will see a data source definition for the frevvo database type name="jdbc/sharedfrevvoDS". See the sample below of the HSQLDB data source in the server.xml file.
- Comment out the pair of the definitions for the default database (HSQLDB) using the <!-- --> comment characters. The entire section must be commented out:
Code Block |
---|
<!-- HSQLDB Resource <Resource auth="Container" type="javax.sql.DataSource" name="jdbc/sharedfrevvoDS" driverClassName="org.hsqldb.jdbcDriver" username="sa" password="" url="jdbc:hsqldb:file:${catalina.home}/../data/db/forms" maxActive="200" maxIdle="20" maxWait="10000" validationQuery="select 1 from INFORMATION_SCHEMA.SYSTEM_USERS" testOnBorrow="true" testOnIdle="true" timeBetweenEvictionRunsMillis="10000" removeAbandoned="true" logAbandoned="true"/> --> |
5. Next, uncomment the pair of definitions for your database. Ex: if you are using SQL server, uncomment the definition for SQLSERVER Resource. Save the changes.
Code Block |
---|
<!-- SQLSERVER Resource --> <Resource auth="Container" maxActive="200" maxIdle="20" maxWait="10000" validationQuery="select 1" testOnBorrow="true" testOnIdle="true" timeBetweenEvictionRunsMillis="10000" removeAbandoned="true" logAbandoned="true" name="jdbc/sharedfrevvoDS" driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver" username="root" password="" type="javax.sql.DataSource" url="jdbc:sqlserver://localhost:1433;databaseName=frevvo;"/> |
Warning | ||
---|---|---|
Database configuration has been removed from the <frevvo-home>\tomcat\conf\Catalina\localhost\frevvo.xml file. It is now done in the C:<frevvo-home>\tomcat\conf\server.xml file. Also, notice the database resource name has been changed to jdbc/sharedfrevvoDS. When you configure your database, make the changes to the server.xml. Do not copy configured sections from a frevvo.xml of a previous release into the server.xml file.

Configure the frevvo database
Note |
---|
The frevvo database below must be created with UTF-8 encoding if you are using international characters. |
For your selected database type in server.xml:
...
For your selected database type in server.xml:1)
- Set the sharedfrevvoDS data source url parameter to your database server. If and the database server are collocated "localhost" may be fine. The url parameters depend on the database type and installation choices made when your DBA installed your database software. Consult your DBA for the correct connection values. For example, SQL server installed on a non-default port and running on a machine named e00sca will require that you add a port number and host name to the Url. For example:
Code Block |
---|
url="jdbc:sqlserver://e00sca:59377;databaseName=frevvo;" |
...
Code Block |
---|
url="jdbc:sqlserver://e00sca:59377;databaseName=frevvo;instance=xyzzy" |

...
. Verify that the user and password required to connect to the frevvo database are correct.
3
...
. Make sure that the user configured in the data sources has permissions to read and write to the frevvo database.
Info | ||
---|---|---|
If you are using SQL Server, it is recommended that you append the sendStringParametersAsUnicode property with a value of false to your database connection URL. This property will improve performance. You can find more information about this property on this Microsoft website. If you do not see the property, when configuring the Connection URL to your database, add it.

...
If you are trying a different database type and do not see an example in server.xml for your database, you can create a new data source entry. Hibernate supports the following dialects however has only been certified to run with a subset of these databases. For additional dialects see Hibernate documentation.

UTF-8 Encoded Database
Warningnote |
---|
The frevvo database must should be created with UTF-8 encoding if you are using international characters. Setting the encoding depends upon the database you are using. Please consult your database documentation. If you're using a improperly encoded database for sharedfrevvoDS you may run into one or more of the following runtime issues:

Setting the encoding depends upon the database you are using. Please consult your database documentation.

...
If you are using SQL Server as your Live Forms frevvo database, it is highly recommended that you turn on the READ COMMITTED SNAPSHOT setting in the database.
You do not have to do this if you are using MySQL or Oracle databases because the option is turned on by default.
There are two ways to turn on the option:
Using DDL (Data Definition Language) - Run the commands listed below
Code Block ALTER DATABASE <your frevvo database schema> - replace <your frevvo database schema> with the name of your frevvo database schema SET READ_COMMITTED_SNAPSHOT ON
- Using SQL Server Management Studio: Turn on the “Is Read Committed Snapshot On” Option under database properties.
Install a JDBC Driver
database relies on the JDBC API. See the list of certified databases. If you choose a database that's not in this list you do so at your own risk.
Warning |
---|
You MUST use a JDBC4 type driver. |
- The download package comes with pre-installed drivers. For example:
- the HSQLDB.jar file is located in WEB-INF/lib in the frevvo.war.
the SQL Server JDBC Driver - this driver (mssql-jdbc-7.2.2.jre11.jar ) is included in the frevvo tomcat bundle in the <frevvo-home>\frevvo\tomcat\lib directory.
Warning At this time, frevvo only supports the v7.2.2.jre11 version of the SQL Server JDBC driver. This version of the driver is included in the frevvo tomcat bundle.
- If you don't
...
- find what you
...
- need pre-installed you will need to locate a driver compatible to your database. Usually you can download your driver from the internet. Try one of these locations:
- MySQL - 8.0.x or later is recommended if you are using MySQL 5.6+
- Oracle
...
- If you are using Oracle12c as your database, the jdbc driver must be
...
- the version 7 ojdbc.
...
- jar which is certified for JDK 7 and 8 for

...
- to function properly.
...
- If you are using Oracle 11g, continue to use
...
- the the ojdbc6 driver
...
- version 11.2.0.3+ which is certified for JDK 6, 7 and 8. Remember JDK 6 and 7 are no longer supported by frevvo.
...
- Once you have the driver you need, copy it to <frevvo-home>/tomcat/lib.
- The <frevvo-home>\tomcat\logs\frevvo.log file will report an error if you do not copy the JDBC driver to lib directory. The verbiage may differ depending on the driver and database. For example, the error for MySQL is "Cannot load JDBC driver class 'com.mysql.cj.jdbc.Driver".
...
- Starting without the correct jdbc driver displays an HTTP 404 error. Copying the correct jdbc driver to the <frevvo-home>/tomcat/lib directory should resolve the issue.
- It is also appropriate to copy the driver into any location that is in the CLASSPATH of your tomcat installation. Another location would be <CATALINA_HOME>/lib.
- Starting without the correct jdbc driver displays an HTTP 404 error. Copying the correct jdbc driver to the <frevvo-home>/tomcat/lib directory should resolve the issue.

Users on Mac OS may see this exception: Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: The server time zone value 'EDT' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support. Customers facing this error should add the serverTimezone=EST5EDT (insert correct timezone) parameter to the jdbc url. |
