Why am I having this problem with java or Windows Installer?

Problem in installing JAVA (Java Virtual machine) in work station computer windows XP professional?

• i am trying to run some utility program on windows XP which needs java should be present in the system, i downloaded the java (j2re1.4.2_04) from the sun site and installed in my D:\program files\java directory. Still i am finding following error message Windows can not find 'javaws', make sure you type the name correctly, and then try again.What may be the problem and probable solution of this proble.i am seeking help

• Answer:

  This is probably because your "PATH" variable does not have your java path. Click on the system icon in control panel. In the "advanced" tab, click on "environment variables". Then highlight the Path variable and click edit. Add the path to the new java directory until the "bin" directory. Click OK and then try typing javaws. Hope this helps.
