Hi Jun-Dir,

I used Active Ports, I cannot find any application uses port 1098. Then I reboot my PC and restart LAMS 2, it works now. Do you know why?

Anyway thanks for your help.

I have a problem on lams web service here. Do you mind give me some suggestions? Thanks in advance.

I use j2ee to create the client for LearnignDesignRepositoryService. everything is fine, I can invoke the service and get the string. But when I move the code into my building blocks it doesn't work. I got this error:

Do you know what's wrong?

I've found that Skype sometimes occupies port 80, when that happens I can't start Apache running on port 80. Perhaps something similar happened to you?

I'm not sure I can help much with your integration code as I'm not familiar with that part of the code. Sorry, can't offer anything off the top of my head. Have you checked if the request was received on the LAMS side? Or what was returned if it was?

This morning I found Skype uses port 1098 & 1099. I'll start skype after launching LAMS2. Thanks.

It's OK. I'll try to find out the reason. I appreciate all the helps you give to me.


Cheers,

Chen
