Spring + LiveCycle Data Services

[a.rubalcaba]

Does anyone know the best way to configure Spring with LiveCycle Data Services? Can I use the same approach as with the Spring BlazeDS integration?

[jeremyg484]

Yes, you can use the exact same configuration as LCDS 2.6 is just adding on to BlazeDS. We don't have explicit support yet for the LCDS-specific Data Management features, but that will be coming soon.

[eliezerreis]

Is there any news about this issue? I'm waiting it for a year so-so

[jeremyg484]

Data Management support will be in the 1.5 release. It hasn't been a top priority because we don't get a lot of demand for it (not surprising, given the cost of LCDS), but it is coming. First milestone is currently targeted for the end of March, and it should include at least basic support.

Does the Spring-BlazeDS Integration 1.0.2 also work with LCDS 3.0?

Thanks!
Paul

[jeremyg484]

No, it does not, because LCDS 3.0 is using BlazeDS 4 (even though BlazeDS 4 has not yet had an official release). It should work, though, with the upcoming 1.0.3 that we'll be releasing this week. 1.0.3 will be binary compatibile with both BlazeDS 3 & 4.

[paulkuhn]

This is good news!! I am looking forward to the 1.0.3 release!!

Thanks a lot!

Hi Jeremy,

thanks for version 1.0.3 !!!

I have tried version Spring-BlazeDS 1.0.3 with LCDS3 and ran into an exception while starting the application. This is the stack trace:

Do you know this exception?
Thanks!
Paul

[jeremyg484]

That stack trace doesn't tell the whole story. There's got to be another exception somewhere that would indicate why the MessageBroker is not getting set up.

Hi,

I got it working, it was the web.xml. I can reproduce the error by changing the web.xml

Isn't it the same and shouldn't the second web.xml also work?

Thanks and kind regards.
