Here you go ...
Step 1: Download the files for 5.0.1
You can download the files here:
Step 2: Shutdown the Apache Tomcat J2EE server
Step 3: Remove the existing JasperReportsLibraries from your existing installation
Typically, after you have installed your previous version of the JasperReportsIntegration toolkit on your Apache Tomcat J2EE server, the files will be located in the directory $CATALINA_HOME/webapps/JasperReportsIntegration/WEB-INF/lib, for example version 4.7.0 of JasperReports, where $CATALINA_HOME represents the path to your installation of Tomcat.
Then you would have to remove these libraries first. In this directory you should find two files for removal: _jasper-reports-delete-libs-4.7.0.sh and _jasper-reports-delete-libs-4.7.0.cmd, for *nix or Windows respectively. For *nix systems you would have to make it executable, though, e.g.: chmod u+x _jasper-reports-delete-libs-4.7.0.sh . Then you can call it and it will remove all files for version 4.7.0. But it will NOT remove the file for the JasperReportsIntegration and all other libraries which YOU might have placed there deliberately.
You can always find the required removal scripts here: http://www.opal-consulting.de/downloads/free_tools/JasperReportsLibraries/ .
Step 4: Install the new 5.0.1 libraries
Now you can just copy the new libraries from JasperReportsLibraries-5.0.1.zip into $CATALINA_HOME/webapps/JasperReportsIntegration/WEB-INF/lib.
Step 5: Start the Apache Tomcat J2EE server again
Now you system should be upgraded to the most current JasperReports 5.0.1 !
Just drop me a note when you need updated libraries for 5.0.2, 5.0.3, ... 6.0.0, etc. I have scripts in place to create a new package of the libraries.
Here you can find the notes from my last upgrade (4.5.0 => 4.8.0), I hope it makes sense:
** ** download the libraries from: ** http://www.opal-consulting.de/downloads/free_tools/JasperReportsLibraries/4.8.0/JasperReportsLibraries-4.8.0.zip ** to /home/jasper/JasperReportsLibraries cd /home/jasper mkdir JasperReportsLibraries ** unzip them cd JasperReportsLibraries unzip JasperReportsLibraries-4.8.0.zip -d JasperReportsLibraries-4.8.0 ** stop tomcat server /home/jasper/tomcat/bin/shutdown.sh ** remove libraries of current jasper reports release cd /home/jasper/tomcat/webapps/JasperReportsIntegration/WEB-INF/lib chmod +x _jasper-reports-delete-libs-4.5.0.sh dos2unix _jasper-reports-delete-libs-4.5.0.sh ./_jasper-reports-delete-libs-4.5.0.sh ** copy libraries of the new release to the WEB-INF/lib directory cp /home/jasper/JasperReportsLibraries/JasperReportsLibraries-4.8.0/* /home/jasper/tomcat/webapps/JasperReportsIntegration/WEB-INF/lib ** restart tomcat /home/jasper/tomcat/bin/startup.shCheers,
