Installation problem

[arvinsc]

when i install the laszlo presentation server, I get a message saying lps needs jdk1.3 or higher and asks me to download. but i have jdk1.3 already installed in my system. i suppose lps is searching some where in the machine for a variable to see if jdk1.3 is installed.

Can any one help me to solve this problem.

I presume that you have the JDK, not just the JRE installed right?

Is the JAVA_HOME variable set correctly?

Has the path to the Java bin directory been added to your PATH?

What operating system are you on?

I set the java_home variable path and it installed correctly.

Thanx Anton.

I am having the same problem. My JAVA_HOME is set correctly as is my PATH, but it still doesn't work.

I can type java-version at the command line and see the following:

java version "1.4.1_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_02-b06)
Java HotSpot(TM) Client VM (build 1.4.1_02-b06, mixed mode)

What OS are you using?

Windows XP

So could you confirm that your JAVA_HOME variable is set to:

C:\j2sdk1.4.1_02

... and the PATH variable contains:

C:\j2sdk1.4.1_02\bin

You might also want to check that your PATH doesn't contain any references to a conflicting version of JAVA (maybe the JRE that ships with Windows?).

My JAVA_HOME is set to:

C:\j2sdk1.4.1_02


My PATH is set to:

c:\j2sdk1.4.1_02\bin;%ANT_HOME%\bin;%SystemRoot%\s ystem32;%SystemRoot%;%SystemRoot%\System32\Wbem;c: \program files\GNU\WinCvs 1.2;C:\Program Files\Microsoft SQL Server\80\Tools\BINN

There's a space in the PATH you posted - is that just a typo, or is it actually there?

-Antun

[mangums]

Not sure where that came from. It is not in my path, my path has the following:

C:\j2sdk1.4.1_02\bin

[antun]

Did you have Java installed before you ran the LPS installer? If so, was there ever a point at which there was a popup window that said "using JDK found in C:\j2sdk1.4.1_02" during the install process?

I have had java 1.4.1 installed for about 6 months on this box.

The only message that I see when I run the install says:
"The Laszlo Presentation Server requires JDK 1.3 or higher. Please download one from http://java.sun.com.

My IE is then directed to "http://java.sun.com/".

The installer looks in your registry to see if you have a valid JDK installed in your system. Can you verify that your JDK is listed under HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit? If it isn't, you may need to run the JDK installer.

For some reason my registry did not have an entry for "Java Development Kit" only "Java Runtime Environment". I re-installed JDK and the install worked. Thanks!
