Posted by Tonda Prukl, Last modified by Tonda Prukl on 21 March 2014 12:26 PM

Why do I need Java for IceWarp WebClient?

Java Runtime Environment (or simply Java) is required for proper functionality of:

  • IceWarp WebPhone, which allows you to make calls directly from within WebClient
  • IceWarp Online Conferencing, which allows you to make conference calls and share your desktop directly from WebClient

Interactive Troubleshooting

Please access the page "WebPhone Setup Guide" for interactive troubleshooting of Java problems: esupport.icewarp.com/java/

Non-interactive Troubleshooting

(for advanced users)

There are several reasons when IceWarp WebPhone or Online Conferencing may not work properly:

  1. Java is not installed at all
  2. Java is installed, but not for the appropriate target platform
  3. Java is installed, but is outdated
  4. Java is installed, but is disabled in your browser

A. Java is not installed

Please go through the following steps in order to install Java:

  1. Download Java installer for your operating system from www.java.com/download/
    • Please note that 32 bit platform or 64 bit platform of Java does not correspond to the platform of Windows, but rather to the version of your browser.
    • It means that for 32 bit Internet Explorer, 32 bit Chrome or 32 bit Firefox on Windows 64 bit you will actually need Java 32 bit (not Java 64 bit).
    • On 64 bit operating system you can however install both 32 bit Java and 64 bit Java in parallel if you need both for any reason.
  2. Install Java
    • Launch installer and go through the installation process.
    • If you do not have administrative permissions, ask your system administrator to help you with the installation.
  3. Verify Java installation by going to www.java.com/verify/

If the verification of Java installation fails, please follow the instructions on the Java Verify page.

B. Java is installed for inappropriate target platform

Please note that for for 32 bit Internet Explorer, 32 bit Chrome or 32 bit Firefox on Windows 64 bit you will actually need Java 32 bit (not Java 64 bit).

You will need to ensure that appropriate version of Java is installed, so please go through steps described in Chapter A.

C. Java is outdated

Please note that your browser may disable Java if it is not updated to the latest version.

You will need to ensure that the latest version of Java is installed, so please go through steps described in Chapter A.

D. Java is disabled in your browser

Even though you have installed the latest and the appropriate version of Java, your browser may still block it from working properly. If this is the case, please

  • Make sure that you have confirmed any popups or alerts in your browser to allow Java to run.
  • Check whether Java is enabled in your browser (follow the instructions on Java Verify page www.java.com/verify/).

In case of further troubles, please ask your system administrator for help.
