WEB Start app and DFS

tvv2000

Hi. I am developing swing application that works with CMS via DFS 6.0 SP1. When I am running it as standalone application it works fine, but when I try to make the same when I start app as web start application I am getting some strange error and what is more strange I am getting it only after second attempt to make the same things.

I am checking out some files in CMS (just lock it without content downloading, because I have local copies already)
I am changing local copies and try to upload them with DFS IVersionControlService.checkin(). I am using UCF as content transferring (because of some restriction of application on server side)

1170 [AWT-EventQueue-0] DEBUG com.emc.documentum.fs.rt.context.impl.UcfSessionManager - getCurrentHttpSession: exception
10.07.2009 15:01:29 WARNING: runtime invoked but not connected, exiting

I was reading some post from this forum and did not find any useful comments about this problem. It looks like that I should set ActivityInfo for ContentTransferProfile.

Actually I do not understand the problem at all. Why application is working fine when it is standalone and became broken when I start it under WEB start.

Some snippets from my code

1. Check out

ObjectIdentitySet ids = new ObjectIdentitySet();

.....
IVersionControlService service = getFactory().getService(IVersionControlService.class);

service.checkout(ids, null);

2. Check in

DataPackage pkg = new DataPackage(.....); OperationOptions options = new OperationOptions(); ContentTransferProfile transferProfile = options.getContentTransferProfile(); transferProfile.setTransferMode(ContentTransferMode.UCF); options.getContentProfile().setFormatFilter(FormatFilter.ANY); options.getPropertyProfile().setFilterMode(PropertyFilterMode.ALL);

pkg = getFactory().getService(IVersionControlService.class).

checkin(pkg, VersionStrategy.NEXT_MINOR, false, null, options);

Any ideas what is wrong I am doing?

Thanks,

Victor

this issue is related with UCF connection.

simply speaking, when you want UCF transfer, the client must get a "JSESSIONID" from the application server. Then this "JSESSIONID" is set into the cookie of the service request, which is used to set up the UCF connection.

Usually, you don't need to set up UCF connection correctly.

Hi.

Thanks, I understand the problem with Ucf connection. But what is wrong? As I sad it works as standalone app and does not work as Web start app. As I see there are some improvements in DFS 6.5 with Ucf connection. Documentum dev team introduced new class UcfConnection where you can can control jsessionid and other stuff. May be my problem cannot be resolved with DFS 6.0 because I am not able to control Ucf connection with DFS 6.0 ?

as far as I know, there is a bug in DFS code when you run DFS client as applet in browser. Such as, if you refresh IE window, UCF connection won't be set up. I'm not sure whether it's the same issue for web start.

Could you give me a link to this bug (may be there is a workaround exist) ? Also I reread documentation and found something confusing. I read in "Setting up your ClassPath for DFS development" for "Remote service consumer application with UCF for content transfer"

The client application must provide the DFS runtime with JSESSIONID and (UCF) activity id data in order for DFS to commence UCF content transfer on the service machine. Please read the DFS Development Guide for more details.

I looked at "Documentum Foundation Services Version 6 SP1" devguide. I see an example with UCFConnection in SampleApplet, but there is no such class in DFS 6.0 SP1.

the bug track system is for internal use only, which you may not have access to it.

pls check the dfs sdk to find the applet sample.

page 182 of dfs dev guide version 6 sp1 should provide you enough info for developing ucf client.

tvv2000

Could you give me bug number (or just copy content of bug) in this case? I looked at samples - there is not sample with applet. I have read in dev guide

The sample application described here is not currently provided in the SDK. (page 177)

I saw the sample with applet only in DFS 6.5 SDK (emc-dfs-sdk-6.5\samples\UcfTransfer\SampleApplet.java). It looks like they did not include UCFConnection to DFS 6.0. That is why there is no SampleApplet.

Thanks,

Victor

The bug number is 748, which is reported as a bug of DFS 6.5 SP2. I'm not sure whether it's also a bug of 6.0 SP1.
