Upgrading from 4.5 - 6.2 to 6.4

This chapter describes the recommended procedure for upgrading from JasperReports Server 4.5 through 6.2 to JasperReports Server 6.4. If you're upgrading from version 6.3 to 6.4, we recommend the procedure in Upgrading from 6.3 to 6.4.

This upgrade procedure uses the JasperReports Server WAR File Distribution ZIP release package and the included buildomatic scripts. Our examples are for upgrading from version 6.2.

Upgrade Steps Overview

These are the general steps used in this section:

1. Plan your upgrade.
2. Back up your current JasperReports Server instance.
3. Export your existing repository data. For example, export your 6.2 data.
4. Download and set up the new 6.4 JasperReports Server WAR file distribution zip.
5. Run the js-upgrade script as described in Upgrading to JasperReports Server 6.4.

Upgrading with Customizations

If your current instance of JasperReports Server has modifications or extensions, keep track of these and re-integrate them into your 6.4 instance after upgrading. See Planning Your Upgrade to determine if any customizations you've made to your existing version of JasperReports Server are affected by changes to the updated version.

Back Up Your JasperReports Server Instance

First back up your JasperReports Server WAR file and jasperserver database so you can restore them if necessary. Perform these steps from the command line in a Windows or Linux shell.

This backup example is for Tomcat with the PostgreSQL or MySQL database. For other databases, consult your DB administration documentation for backup information.

Back up your JasperReports Server War File:

1. Create a folder where you can save your jasperserver war file. For example, C:\JS_BACKUP or /opt/JS_BACKUP.
2. Copy <tomcat>/webapps/jasperserver  to  <path>/JS_BACKUP

Back up your jasperserver Database:

1. Create a folder (if you did not do so in the step above) where you can save your jasperserver database, For example, C:\JS_BACKUP or /opt/JS_BACKUP.
2. Run the following commands for PostgreSQL or MySQL:
     PostgreSQL

cd <path>/JS_BACKUP

pg_dump --username=postgres  jasperserver  >  js-db-dump.sql

     MySQL

cd <path>/JS_BACKUP

Windows:

mysqldump --user=root --password=<password> jasperserver > js-db-dump.sql

Linux:

mysqldump --user=root --password=<password> --host=127.0.0.1 jasperserver ><br />js-db-dump.sql

For MySQL, If you receive an error about packet size, see the Troubleshooting appendix of the JasperReports Server Community Project Installation Guide.

Exporting Current Repository Data

You need to export your old repository data. Use the JasperReports Server export utility to export using:

the buildomatic scripts (if you originally installed using buildomatic).
the js-export-ce.bat/.sh script found in the <js-install>/buildomatic folder.

Using Buildomatic Scripts to Export Data

If you configured buildomatic and your default_master.properties file for export as described in the JasperReports Server Community Project Administrator Guide, you can use buildomatic to export your repository data. For example, to export 6.2 repository data, use the following commands:

1. Navigate to the buildomatic directory:

cd <js-install-6.2>/buildomatic

2. Run buildomatic with the export target:

Windows:

js-ant.bat export-everything<MadCap:conditionalText data-mc-conditions="JasperConditions.Community">-ce</MadCap:conditionalText> -DexportFile=js-<span class="UpgradeVariablesOlderPointVersion">6.2</span>-export.zip

Linux:

./js-ant export-everything<MadCap:conditionalText data-mc-conditions="JasperConditions.Community">-ce</MadCap:conditionalText> -DexportFile=js-<span class="UpgradeVariablesOlderPointVersion">6.2</span>-export.zip

Note the location of this export file so that you can use it during the 6.4 upgrade process.

Using the js-export Script to Export Data

To use the js-export-ce.bat/.sh script, navigate to the buildomatic folder, for example, <js‑install‑6.2>/buildomatic. If you're using the PostgreSQL database the js-export script should already be configured to run. If you're using a different database, or you've changed database passwords, you may need to update the js‑export configuration.

Run the following commands:

1. Navigate to the buildomatic directory:

cd <js-install-6.2>/buildomatic

2. Run the js-export script:

Windows:

js-export<MadCap:conditionalText data-mc-conditions="JasperConditions.Community">-ce</MadCap:conditionalText>.bat --everything --output-zip js-<span class="UpgradeVariablesOlderPointVersion">6.2</span>-export.zip

Linux:

js-export<MadCap:conditionalText data-mc-conditions="JasperConditions.Community">-ce</MadCap:conditionalText>.sh --everything --output-zip js-<span class="UpgradeVariablesOlderPointVersion">6.2</span>-export.zip

Note the location of this export file so that you can use it during the 6.4 upgrade process.

Preparing the JasperReports Server 6.4 WAR File Distribution

Use the buildomatic js-upgrade scripts included in the 6.4 WAR file distribution ZIP release package to carry out the upgrade. The WAR file distribution comes in a compressed ZIP file named TIB_js-jrs_cp_6.4.0_bin.zip.

Follow these steps to obtain and unpack the WAR file distribution ZIP file:

1. Download the WAR file distribution from the Jaspersoft community site (http://community.jaspersoft.com).
2. Extract all files from TIB_js-jrs_cp_6.4.0_bin.zip. Choose a destination, such as a C:\Jaspersoft folder on Windows, /home/<user> on Linux, or /Users/<user> on Mac.

After you unpack the WAR File Distribution, the resulting location will be known as:

<js-install-6.4>

Configuring Buildomatic for Your Database and Application Server

This upgrade procedure uses the js-upgrade-newdb-ce shell script.

For Unix, the bash shell is required for the js-upgrade scripts. If you're installing to a non-Linux Unix platform such as HP-UX, IBM AIX, FreeBSD or Solaris, you need to download and install the bash shell. See the Troubleshooting appendix of the JasperReports Server Community Project Installation Guide for more information.

This section shows example configurations for the PostgreSQL and MySQL databases.

Example Buildomatic Configuration

The default_master.properties file handles the upgrade configuration. We provide a sample configuration file for each database. You must specify your database credentials and application server location, and rename the file to default_master.properties.

PostgreSQL Example

To configure default_master.properties for PostgreSQL:

1. Locate the postgresql_master.properties sample configuration file:

Database

Master Properties File

PostgreSQL

<js-install-6.4>/buildomatic/sample_conf/postgresql_master.properties

2. Copy the file to <js-install-6.4>/buildomatic
3. Rename the file default_master.properties
4. Edit default_master.properties for your database and application server:

Database

Sample Property Values

PostgreSQL

appServerType=tomcat6 [tomcat7, jboss, glassfish2, glassfish3]
appServerDir=c:\\Apache Software Foundation\\Tomcat 7
dbUsername=postgres
dbPassword=postgres
dbHost=localhost

MySQL Example

To configure default_master.properties for MySQL:

1. Locate the mysql_master.properties sample configuration file:

Database

Master Properties File

MySQL

<js-install-6.4>/buildomatic/sample_conf/mysql_master.properties

2. Copy the file to <js-install-6.4>/buildomatic
3. Rename the file default_master.properties
4. Edit default_master.properties for your database and application server.

Database

Sample Property Values

MySQL

appServerType=tomcat6 [tomcat7, jboss, glassfish2, glassfish3]
appServerDir=C:\\Apache Software Foundation\\Tomcat 7
dbUsername=root
dbPassword=password
dbHost=localhost

Upgrading to JasperReports Server 6.4

Now that your buildomatic scripts are configured, you can complete the upgrade.

Make sure you've backed up your jasperserver database before proceeding.

Make sure you've backed up your old JasperReports Server WAR file before proceeding.

1. Stop your application server
2. Start your database server
3. Run the following commands:

Commands

Description

cd <js-install-6.4>/buildomatic

Change to buildomatic directory

js-upgrade-newdb-ce.bat <path>\js-6.2-export.zip

(Windows) Upgrade jasperserver war file, drop and recreate the database, import data file from previous version.

./js-upgrade-newdb-ce.sh <path>/js-6.2-export.zip

(Linux) Upgrade jasperserver war file, drop and recreate the database, import data file from previous version.

On MySQL, if you receive an error about packet size, see the Troubleshooting appendix of the JasperReports Server Community Project Installation Guide.

js-upgrade Test Mode

Use the test option to run the js-upgrade script in test mode. For example, on Windows, enter:

cd <js-install-6.4>/buildomatic

js-upgrade-newdb-ce.bat test <path>/js-6.2-export.zip

In test mode, the js-upgrade scripts check your default_master.properties settings and validate your application server location and its ability to connect to your database. Test mode can help you debug issues like an incorrect database password without altering your system.

Output Log Location

The js-upgrade script creates an output log that captures both standard and error output. If problems occur during script execution, or you just want to remember which options you chose, open the output log file located here:

<js-install-6.4>/buildomatic/logs/js-upgrade-<date>-<number>.log

Errors

If you encounter errors running the js-upgrade script, first look at the output log to see if you can spot the errors. For help, refer to the Troubleshooting appendix of the JasperReports Server Community Project Installation Guide. The information in this appendix applies to both js-upgrade scripts and js-install scripts.

If you need to modify values in your default_master.properties file, you can simply edit the file. When you run the js‑upgrade script again, it uses the new values.

Starting and Logging into JasperReports Server 6.4

Start your application server. Your database should already be running.

Clearing Your Browser Cache

Before you log in, make sure you and your end users clear the browser cache. JavaScript files, which enable the UI elements of JasperReports Server, are typically cached by the browser. Clear the cache to ensure that the newer files are used.

Logging into JasperReports Server

Log in using the following URL, user IDs, and passwords:

URL: http://localhost:8080/jasperserver

User ID

Password

Description

jasperadmin <your-password>

Administrator for the default organization

Your JasperReports Server instance has now been upgraded to 6.4. If you have startup or login problems, refer to the Troubleshooting appendix of the JasperReports Server Community Project Installation Guide.

Additional Tasks to Complete the Upgrade

Perform these tasks with the application server shutdown.

Handling JasperReports Server Customizations

If you made modifications to the original JasperReports Server application, these configurations are typically found in the WEB-INF/applicationContext-*.xml set of files.

You'll need to manually copy configuration changes, like client-specific security classes or LDAP server configurations, from your previous environment and integrate them with your upgraded environment.

Clearing the Application Server Work Folder

Application servers have work folders where JasperReports Server files are compiled and cached and other objects are stored. When you update the WAR file, the buildomatic deploy-webapp-ce target should automatically clear the application server’s work directory, but it’s a good practice to double-check. A permission problem, or some other problem, could prevent the clearing of the work folder.

To clear the work folder in Tomcat:

1. Change directory to <tomcat>/work.
2. Delete all the files and folders in this directory.

Clearing the Application Server Temp Folder

JasperReports Server uses caching to speed operations within the application. Caching files are created and stored in the application server, usually in a temp folder. Clear this temp folder to avoid any post-upgrade conflicts. Typically, the temp folder used by an application server corresponds to the path referenced by the java.io.tmpdir Java system property. For Apache Tomcat the temp folder is <tomcat>/temp.

To clear the temp folder in Apache Tomcat:

1. Change directory to <tomcat>/temp
2. Delete all the files and folders in this directory

Clearing the Repository Cache Database Table

In the jasperserver database, compiled JasperReports Library resources are cached in the JIRepositoryCache table for increased efficiency at runtime. Because the JasperReports Library JAR is typically updated with each new release, old cached items can get out of date and cause errors at runtime. If you encounter errors that mention a JasperReports Library “local class incompatible,” check your repository cache table. In summary, you can clear your jasperserver database cache table as part of this upgrade process whether or not there are errors.

To manually clear the repository cache database table, run a SQL command similar to one shown below:

update JIRepositoryCache set item_reference = null;

delete from JIRepositoryCache;

Old Manual Upgrade Steps

This section describes the older, manual upgrade steps used before we implemented the js-upgrade shell scripts in release 4.0. They're provided here mainly as a reference for internal use.

We recommend using the js-upgrade shell scripts described in the beginning of this chapter instead of these manual commands.

Commands

Description

cd <js-install-6.4>/buildomatic

js-ant drop-js-db

js-ant create-js-db

js-ant init-js-db-ce

Deletes and recreates your jasperserver db. Make sure your original database is backed up.

js-ant import-minimal-ce

js-ant import-upgrade

-DimportFile="<path-and-filename>"

The -DimportFile should point to the <path> and <filename> of the js-6.2-export.zip file you created earlier.

On Windows, you must use double quotation marks (“) if your path or filename contains spaces. On Linux, you must use double quotation marks, escaped with a backslash (\”) in this case.

Note: "import-upgrade" will import resources from the 6.2 instance in a "non-update" mode (so that core resources from 6.4 will stay unchanged). Additionally, the "update-core-users" option will be applied so that the superuser and jasperadmin users will have the same password as set in the 6.2 instance.

js-ant import-sample-data-upgrade-ce

(Optional) This step is optional; it loads the new sample data. The old sample data is overwritten, so you may need to redo certain changes such as configuring the sample data sources for your database.

js-ant deploy-webapp-ce

Deletes the existing older war file, deploys the new war file.
