3.4. Verifying the Downloaded Files
The software details page for each download also contains the MD5 checksum values for that download. These values are used to verify the integrity of your downloaded files. You can use the
md5sumutility as detailed below to calculate the checksum values of the files to compare to the supplied values on the website. The checksum values are also documented in Table 3.1, “JBoss EAP MD5 checksum values” for completeness.
The command line examples given are accurate for most Linux and Unix operating systems. Mac OS X includes the equivalent command
If you are using Microsoft Windows you will have to download a third party utility to perform these steps as it does not include a MD5SUM tool.
After you have downloaded the file, run the
md5sumutility and specify the file you downloaded as the first argument as demonstrated here:
Example 3.1. Using the md5sum tool on Linux or Unix
$ md5sum jboss-eap-4.3.0.GA_CP03.zip 4ebffbd38fcb7e259d1d9abbd40b058a jboss-eap-4.3.0.GA_CP03.zip
The values that are generated by the
md5sumutility must be the same as both the values that are displayed on the Downloads page for the file and those documented in Table 3.1, “JBoss EAP MD5 checksum values”. If they are not the same then then your download is either incomplete or corrupted. You will need to download it again. If after several attempts you are unable to download a copy of the file that produces a valid checksum values you should open a support case to report the problem.
Below is the complete list of the MD5 checksums for all the JBoss EAP packages available for download.
