Hi Raj, it’s hard to tell without seeing your configuration file, but it looks like you have some invalid data in the port value for your HTTPServer manager configuration - it should be a positive integer, but it appears to be something else. HTH, Matt ---

Can you please attach your complete correlator log? ---

Hi there Raj, Maybe you could mention the location you got this sample from (whether in your Apama installation or from a webpage)? The tutorial sample provided with the product that uses Temperature is installed at APAMA\_HOME\tutorials\EPL\_FundamentalsCompleted but doesn’t use the HTTPServer so I guess you’re looking at something different? Are you using the project from Software AG Designer? If so, there will be a node in the project explorer underneath your project providing easy access to the connectivity plugin configuration files. If not, look in /config. The HTTP server port will be in one of the .properties files. Hope that helps ---

Thanks Ben for your reply. I have changed the properties for HTTPServer as you mentioned but there is UMconnectivity error. Here is what i am doing 1. Created new project based on Apama tutorial 2. After adding the code that writes message to screen run the project 3. so after running the project i get error Now the error is related to UMconnectivity 2018-05-15 13:51:46.149 ERROR [8736] - Connectivity plug-ins: Exception while creating chain manager umTransport.umManager: Error while opening: UMConnectivity.dll or a library it depends on for the plug-in: umManager: The specified module could not be found.

Hi Raj, The UM libraries are not included as part of the Apama Community download because UM is a commercial product. Hope that helps to answer your issue. Dan ---

I’m still intrigued by which tutorial this is you’re following. Maybe you could mention the location you got this sample from (whether in your Apama installation or from a webpage)?

Ben and others, I found that when creating new Apama project, some default bundles are auto selected, which is the reason for these HTTPServer and UMConnectivity issues. Thanks, Raj ---

Ah OK that makes sense. When you create a project you are given the choice to add some connectivity as part of the process, and whatever options you select are used as defaults next time you create a project, to save time. So you would have previously created a project with those connectivity options and perhaps omitted to remove them the next time you create a project. Either way, if you don’t need them in this project, just use right-click menu in the project explorer to remove them. ---
