Hi Luis,

I came across the same problem when I tried to run Tomcat with version 11 of the JRE from AdoptOpenJDK.

There are essentially two problems that occur during the Catalina start sequence:
1) The script c:\xampp\catalina_start.bat is looking in certain places of the Registry to determine the installation location of the JRE. However, the keys for the newer JREs are a bit different than the ones used by earlier versions.
2) The script c:\xampp\tomcat\bin\catalina.bat is starting tomcat with the option -Djava.endorsed.dirs which is deprecated and causes the JVM to fail the start-up.

I have cooked up a quick hack this morning to solve my problem. These to changes might help you, but there not quite production ready.
In c:\xampp\catalina_start.bat, you need to apply the following diff:
Code: Select all

 )


You might also have to set $JAVA_HOME in order to bypass other tests. In addition, you should use the latest XAMPP which have a c:\xampp\tomcat\bin\catalina.bat that considers the changes to the endorsed dirs in Java 9 and later.

I hope this helps to get you started.

Jonas

Hi,

Thanks for reporting this issue and for posting here a solution. We have been working on adding the checks for this registry entry and others for the JDK version and we plan to release a new revision of our installers soon.

Regards,
Gonzalo

Hi,

We released a new revision of the XAMPP products adding support for AdoptOpenJDK on Windows platforms. The installers adding this new features are 7.1.32-2, 7.2.23-1 and 7.3.10-1.

Hi,

I am completely new in this forum but using XAMPP as my first test and development environment since... damn I'm getting old. :D

As a small note to the catalina_start.bat:
The script requires at least one of the keys in the windows registry.
My problem is, that it does not check for existing environment variables. If the registry entries are not defined, the script does not start tomcat, even if JAVA_HOME or JRE_HOME are already set.

Thus my small rework for the catalina_start.bat in the xampp directory:

I have modified the section FINDJRE32 not to go to ENDERROR and added two new section to take care of existing environment variables:
Code: Select all
:FINDJRE32
reg query "%JREKeyName32%" /s
if %ERRORLEVEL% EQU 1 (
    echo . [XAMPP]: Could not find 32 bit JRE
    echo . [XAMPP]: Could not set JAVA_HOME or JRE_HOME. Looking for existing environment variables
    goto FINDJDKENV
)
set KeyName=%JREKeyName32%
goto JRERUN

:FINDJDKENV
if NOT DEFINED JAVA_HOME (
   echo . [XAMPP]: Could not find environment variable JAVA_HOME
   echo . [XAMPP]: Looking environment variable JRE_HOME
   goto FINDJREENV
)
goto JDKRUN

:FINDJREENV
if NOT DEFINED JRE_HOME (
   echo . [XAMPP]: Could not find environment variable JRE_HOME
   echo . [XAMPP]: Could not verify java location by reg query or environment variables
   goto ENDERROR
)
goto JRERUN


IMHO the environment variables should checked first instead of querying the registry.
Because first, the installers of Java might have already set the environment variables, second it is more handy on a system with multiple Java installations, third most of the documentations and advices are about the environment variables.
But this would be a matter of taste if not even philosophical.

Greetings
Stefan

Hi Cazeh,

Can you tell us which version of PHP are you using? Which installer? i.e. `7.4.1-0`, `7.2.21-2`, etc.

Also, which JAVA distribution name and version? I mean, is it AdoptOpenJDK version `jdk8u242-b08` or any other JAVA distribution and version? Do you have the link to download it? Do you know the registry entries it added if any? Please give us as much information as possible so we can try to reproduce your issue.
