Installing and configuring a JVM

Ensure that you have a Java virtual machine (JVM) installed that HCAA recognizes.

About this task

HCL Client Application Access (HCAA) does not provide a JVM, used to access Java applications. Instead, it uses a JVM that you install. HCAA automatically recognizes and uses an Oracle JVM release 1.6 or later. If you use an earlier version of an Oracle JVM or a JVM from a different company, after you install HCAA, follow these steps to enable HCAA to use it.

HCAA supports 32-bit JVM only, not 64-bit.


  1. To test whether Oracle JVM version 1.6 or later is installed, enter the following command at the command prompt:


    If Oracle JVM 1.6 or later is installed, skip the rest of this procedure.

  2. Open the HCAA NOTES.INI file, which is in C:\Program Files(x86)\HCL\HCAA, by default.
  3. Add the setting JVMDirectoryLocation= and specify the location of the JVM on the computer. The typical location is C:\Program Files (x86)\Java\jre8.
  4. Add the setting JavaOracleVM= and specify one of the following values:
    • If you use an Oracle JVM, specify 1.
    • If you use a JVM from a different company, specify 0.
