Re: Trying to write a simple partition example

hi Stefan,

   the partition impl requires few changes(at least to pass the test)
   which I have attached as a patch.

Hi all,

I try to write a very (!) simple example for a custom partition, in order tom provide a starting point in the docs. Unfortunately I fail to add my implementation to the DirectoryService, and I have no idea why.

This is how I add my partition ...

--8<--

directoryService = new DefaultDirectoryService();
directoryService.setShutdownHookEnabled(true);

// Determine an appropriate working directory
File workingDir = new File("work");
directoryService.setWorkingDirectory(workingDir);

// Create a new partition
EnvironmentPartition envPartition = new EnvironmentPartition();
envPartition.setId("env");
envPartition.setSuffix("ou=env");
envPartition.init(directoryService);

directoryService.addPartition(envPartition);
directoryService.startup();

-->8--

EnvironmentPartition is my implementation of the Partition interface. Currently it does not make a lot, I was just trying to add it and start the server. Adding is successful, but calling the startUp() method causes an exception:

Although it is totally clear to my, that my partition won't work (most methost throw an OperationNotSupportedException), I thought about starting by simply adding it and starting the server correctly.

I was able to determin that getUpSuffixDn() and getSuffixDn() have been called fom my partition. I assume, that I

a) do not return valid values
b) adding as described above is not sufficient

Does anybody have any idea. I have provided my code as a maven project here:

https://svn.apache.org/repos/asf/directory/sandbox/szoerner/envpartition

Thanks in advance,
    Stefan
