Thread: Where is my JDK

  1. #1

    Default Where is my JDK

    Hi,
    I installed Oracle's sqldeveloper recently. Now, when I try to start sqldeveloper it asks for the "full pathname of a J2SE installation" and also says "the path will be stored in ~/.sqldeveloper/jdk".
    I checked and there is no ".sqldeveloper" directory in my home folder. I listed the files in "/usr/lib/jvm" but I do not know which one is the JDK file it is asking for. The listing is
    :
    drwxr-xr-x 3 root root 4096 2009-02-22 22:10 java-1.6.0-openjdk-1.2_b11
    lrwxrwxrwx 1 root root 30 2009-02-22 22:10 jre-1.6.0-openjdk -> java-1.6.0-openjdk-1.2_b11/jre
    lrwxrwxrwx 1 root root 29 2009-02-22 22:10 jre-openjdk -> /etc/alternatives/jre_openjdk
    lrwxrwxrwx 1 root root 27 2009-02-22 22:10 jre-1.6.0 -> /etc/alternatives/jre_1.6.0
    lrwxrwxrwx 1 root root 21 2009-02-22 22:10 jre -> /etc/alternatives/jre
    lrwxrwxrwx 1 root root 25 2009-02-22 22:11 jre-gcj -> /etc/alternatives/jre_gcj
    lrwxrwxrwx 1 root root 30 2009-02-22 22:11 jre-1.5.0-gcj -> java-1.5.0-gcj-4.3-1.5.0.0/jre
    drwxr-xr-x 3 root root 4096 2009-02-22 22:11 java-1.5.0-gcj-4.3-1.5.0.0
    lrwxrwxrwx 1 root root 27 2009-02-22 22:11 jre-1.5.0 -> /etc/alternatives/jre_1.5.0


    My $JAVA_HOME is set as "/usr/lib/jvm/jre". I tried installing jdk-6u12-linux-i586-rpm.bin but YaST says it is already installed.

    Any help will be greatly appreciated......

    This may not be the ultimate answer, but maybe this helps to see it from another perspective:

    1) You start for the first time. It tells you that it will create ~/.sqldeveloper/jdk, so most probalbly it does not exist already (as you found out).

    2) It asks for a path, not for a file. In other words IMHO it wants to know in which directory it can find the product.

    To find the file for any RPM query the RPM database using that package's
    name. In your case I would try:

    rpm -ql jdk-6u12-linux

    To find binaries the crude way from that:

    rpm -ql jdk-6u12-linux | grep bin

    Good luck.

    Thank You Everyone

    Actually I got everything working. The path of JDK is displayed in the YaST itself. I clicked the JDK in YaST and it told me the path. When I executed sqldeveloper first time it created a .sqldeveloper directory in $HOME. I created a file "jdk" in it and put the path of JDK in that. Now it is working perfectly

    But I put myself in big trouble. I accidently deleted "popper-data" during YaST installation. Now I cannor access my web connection and I do not know how to get back popper-data back without my web connection. Any suggestions???
