Jkd -- Sdk

[kentyler]

To install the new Java 2 JDK you have to download and install the SDK. For me at least this was VERY confusing. If you just go to sun and search on JDK 1.3 you get an endless maze of links and I at least could never find a page that downloaded anything called the 1.3 JDK.

This might be a real problem for people trying to install who aren't already familiar with the sun site and with all the different (and changing) java product nomenclature.

Hey Ken,

Thanks for the note.

We do really need to make the install
experience simple and we aren't happy
about the additional JDK download today.

LPS DR bundles a servlet container (Tomcat) that requires the JDK.
Sun doesn't allow folks to distribute
the JDK or we would.


Sun does allow the JRE to be distributed,
though, and we may bundle it with
our install in the future (assuming we
can safely remove the JDK dependencies from Tomcat or find another simple
servlet container).

Best,
-Eric

Hi,

Is this the windows installer?
There is a known issue where
it doesn't work correctly if you
run it from the command line.

Are you double clicking it or
running it from a command line?

-Eric

[a_thiagarajan]

I am double clicking it..

I even tried opening the cmd window and tried to key in the command line..

In either case , the result is the same..

Hi

How did you install jdk1.3.1?
Did you run Sun's installer?

-Eric

[a_thiagarajan]

I downloaded the following from sun website
(My PC is Win2000)

j2sdk-1_3_1_07-windows-i586.exe

I double clicked on this file name in Windows
Explorer.

It brought up the InstallShield Wizard and
I did the installation thru it.

Is there a different way ( with Sun Installer??)
to do this on PCs.

Hi Thiagu,

The installer looks in the registry to see if you have a valid version of the JDK installed. I was wondering if you could possibly take a quick look in there? Run regedit from the command line, look under
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit, and see if you have 1.3.1_07 listed.

Another thing that would help is sending me your Java registry settings. Could you run the following from your command prompt and send the dump to pkang@laszlosystems.com?

REGEDIT.EXE /e javaregdump "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit"

I can also try calling you.

Thanks,
pablo

I checked in REGEDIT...

yes it is listed ..

I tried running the command you mentioned in the cmd
window..

It gave the C: prompt and there is no dump as you have
mentioned. So I am not sure whether this command is ok?


Thiagu

[pablo]

Sorry for the confusion. Did you run regedit with the "/e" option?

REGEDIT.EXE /e javaregdump "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit"

It should dump a file called javaregdump in the same directory.

pablo

[a_thiagarajan]

Ok I found the dump file..

Here are its contents

REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit]
"CurrentVersion"="1.3"

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit\1.3]
"JavaHome"="C:\\jdk1.3.1_07"
"MicroVersion"="1"

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit\1.3.1_07]
"JavaHome"="C:\\jdk1.3.1_07"
"MicroVersion"="1"

Would it be possible to send me that file? The installer uses that dump to determine which JDKs are available in your system.

Thanks,
pablo

[pablo]

Thanks, I just got the attached file. I think I know what the problem is.

The installer was tested using regedit 5.0, which includes special characters in its dump. The installer parses those special characters out and extracts the necessary information.

Your system uses regedit 4.0, which uses a straight text dump format that the installer doesn't currently handle.

We should have a fix very shortly. Thanks for your patience!

Hey Thiagu,

Could you tell us what version of Windows 2000 you have installed on your system by clicking the right mouse button on the "My Computer" desktop icon? We'd like to test the new installer against that version.

Thanks,
pablo

[pablo]

We just posted a new version of the installer on the website. Could you try it out and let us know if this fixes the problem?

Thanks,
pablo

Hi Pablo,

thank you... the new version worked.. installation went thru.. I have started to try it.
I have written a few apps with IE on the client side using XMLHTTP and XMLDOM (ActivexObjects)
and servlets reading XML input streams (requests) and sending out XML streams( response). This
worked great as the pages made connections to the back end for data.. and the experience was
"cinematic" as u people say.

But thsi approach was not welcome with corp clients.. who want it all JAVA..and no Microsoft (Activex)
Now your product comes along with similar features (may be more) .. let me see if this is what would
gain acceptance..

Keep up the good work.. I think you people need more visibility.. Also attract developers to use your
stuff.. free download / licence is very good.. at least for a while.. also awards for good samples will help.

Thanks
Thiagu
