remove Java

I think one of the repeated suggestions on this forum has been to remove all Java installations from the PC when we are installing the Netweaver Preview edition. I am planning to go ahead with installing the preview edition and I have Jdk1.4.2_08 installed on my PC. I would like to know whether this is an absolute must and whether it also involves removing references to the Path and classpath variables set on the individual system.

    I don't think that you want to remove that, depending on which preview you are referring to, you may need it. Which one are you referring to.

    Hi All,

    It is absolut not necesarry to remove any installed JDK from your system before installing a SAP Netweaver system (it is no Problem to have different Java versions installed on one systems). SAPInst is so intelligent to find the right version (and if not you will be prompted to apply the directory where a supplied JDK is installed >= 1.4.2_8).

    My experience showed me, to awoid any problems during installation, set JAVA_HOME to a supplied version before installing. That's all. Doesn't face any problem with different JDK versions on one machine (e.g. have 1.5, 1.4, and 1.3 installed, don't ask why it's not my server 😊).

    And always use the newest version of JDK 1.4.2!!! (see SAP notes for detail why)
