Solving installation problems

Below are some known problems you may encounter during the installation. In the event of this happening, see this section first before seeking help.

JReport Enterprise Server installer cannot find JVM

To perform the installation, the JReport Enterprise Server installer must find and verify a suitable JVM. However, in rare cases, the installer cannot pass the JVM verification procedure. You will get an error such as JVM not found even when there is already a JDK installed. The steps below describe a method for bypassing the JVM verification process during installation. Here JReport Enterprise Server for UNIX is used as the example for the steps:

  1. Download the JReport Enterprise Server installation file EntSvrSetup.sh into a directory from the Jinfonet download center: http://www.jinfonet.com/downloadjreport/.
  2. Open a console and go to the directory where you saved your installation file. Then use the command:

    $ sh EntSvrSetup.sh -is:extract

    to extract the installation file. This option creates a temporary folder (for example, named istemp39400) in the current directory, and then extracts installation files into the new directory.

    Note: For a Windows machine, no folder will be created. You will find the extracted files in the current directory.

  3. Go to the new directory, and run $ java -jar EntSvrSetup.jar.

    This will launch a GUI installer. Follow the steps in section Installing using the Installation Wizard to finish the installation.

No enough space for the temp directory

The InstallShield Wizard will generate temporary files during installation. You can specify the temp directory with the -is:tempdir option as below. Otherwise, a system temp directory will be used, in which case, make sure that there is enough space for the temporary files. If there is not enough space, a warning dialog will be shown. The temporary files are removed automatically once the installation is complete.

EntSvrSetup.exe -is:tempdir c:\temp

or

$ sh EntSvrSetup.sh -is:tempdir /tmp

If you run into any problems when installing JReport Enterprise Server, you can use this command to log the debug messages:

EntSvrSetup.exe -is:log c:\DebugMessage.txt

or

$ sh EntSvrSetup.sh -is:log /tmp/DebugMessage.txt
