Because this works manually, but not from the Delphi ShellExecute, I'm 
going to point directly at Delphi as source of the issue.  You'll need 
to find out more about ShellExecute, and how to ensure that the 
environment is passed to child processes.

Is there documentation for ShellExecute?  What does it say?

Hi

the doc says

HINSTANCE ShellExecute(
    HWND hwnd,	// handle to parent window
    LPCTSTR lpOperation,	// pointer to string that specifies operation to perform
    LPCTSTR lpFile,	// pointer to filename or folder name string
    LPCTSTR lpParameters,	// pointer to string that specifies executable-file parameters 
    LPCTSTR lpDirectory,	// pointer to string that specifies default directory
    INT nShowCmd 	// whether file is shown when opened
   );

at the moment im using

 NewInstance := ShellExecute(Application.Handle,'open',
    pchar(CfgInfo.RemotePath),'',NIL, SW_SHOWNORMAL);

Do i need the defaut directory perhaps?!
pchar(CfgInfo.RemotePath) is the path to my Java executable.

Hi,

i think ive solved the issue. I dont use ShellExecute, but instead 

Result:= Windows.CreateProcess(
    nil, //AppName
    PChar(anAppName+' '+aCmdLine), //CmdLine
    nil, //ProcessSecurity
    nil, //ThreadSecurity
    False, //Handle Inheritance
    NORMAL_PRIORITY_CLASS, //Creation Flags
    nil, //Environment
    PChar(ExtractFilePath(anAppName)), //Dir
    lStartupInfo,
    lProcessInfo
  );

if Environment is passed as nil then the environment of the parent process is being passed (i suspect that ShellExecute uses an "empty environment"?!).

thanks for the hints (as you said Java was innocent here :) )
