Re: [Wrapper-user] Unable to load the Wrapper's nativelibrary 'wrapper.dll'

[Dominik.S <Dom...@se...>]

Hi,

well what i am doing is something different. I am within a java
application where i use the wrapper.jar to check if a w32 user is in the
"Administrators" group. So the wrapper is called out of a java
application:

Here is my code:

######################################################
###                                                ###
boolean userHasAdministratorRights =3D false;
final String javaLibraryPath =3D pathToWrapperLibDir + ";" +
defaultJavaLibraryPath;
System.setProperty("java.library.path", javaLibraryPath);

// set some wrapper properties:
System.setProperty("wrapper.debug", "TRUE");
System.setProperty("wrapper.native_library", "wrapper");
       =20
// Check if wrapper.dll is readable:
File wrapperDll =3D new File (pathToWrapperDll);
System.out.println("*********************");
System.out.println("java.library.path   : " +
System.getProperty(PROPERTY_JAVA_LIBRARY_PATH));
System.out.println("wrapper.dll location: " + pathToWrapperDll);
System.out.println("wrapper.dll is file : " + wrapperDll.isFile());
System.out.println("wrapper.dll can read: " + wrapperDll.canRead());
System.out.println("*********************");
       =20
// Get all groups the user belongs to:
final WrapperGroup[] groups =3D =
WrapperManager.getUser(true).getGroups();
WrapperWin32Group winGroup;
for(int i=3D0; i<groups.length; i++) {
    winGroup =3D (WrapperWin32Group) groups[i];
    if(winGroup.getSID().equals(ADMINISTRATORS_GROUP_SID)) {
        userHasAdministratorRights =3D true;
        break;
    }
}
###                                                ###
######################################################


So, i think the wrapper.exe is never used (but perhaps i am completly
wrong).=20

Also i do not know hot to tell the wrapper where he could look for the
wrapper.conf (since i do not use the wrapper.exe but a java application
that uses wrapper.jar. Thats why i set the wrapper parameters by:
System.setProperty("wrapper.debug", "TRUE");


I get the following output when running the application.
