Adventures of a service oriented architect
As I’ve mentioned earlier, I like to re-use my existing code whenever possible (and if not possible I’ll try to find a way ;-)). When writing Java Services in webMethods’ Integration Server, I wanted to use an existing method that provides easy access and type safety when working with the service pipeline (i.e. interface IData). … Read more
I created a Java Service in webMethod’s Integration Server that should log something to the server.log file. As it turns out, this is quite simple: Generate Java code for calling the internal Service pub.flow.debugLog by right-clicking on the Service in Software AG Designer and selecting “Generate Code…”, “For calling this service from another service”. The … Read more
Today, I wanted to use the JDBC adapter in webMethod’s Integration Server to connect to a database from a Java service. As it turns out, the configuration was quite frustrating for me. Here’s a history of the problems that appeared while trying to get a database connection running: Error encountered [ART.118.5042] Adapter Runtime (Connection): Unable … Read more
I published several Natural subprograms as a service in webMethods Integration Server via the EntireX adapter which uses a Natural RPC server on our SuSE Linux server to access the Natural modules. After a Natural service has not been called from the outside for a certain period of time (about 1 hour), the next call … Read more
Apparently, creating and deploying an web service with Java EE 7 is just as easy as it was with Java EE 6. This maybe due to the fact, that support for web services and SOAP in JAX-WS hasn’t changed much since Java EE 6, as Adam Bien points out here: The State of SOAP / … Read more
Modularization is an important concept of programming. So, when I wanted to create a Java Service in webMethods’ Integration Server today, I wanted to re-use my existing Java code that already provided the feature I wanted to publish as a Service. However, this is not as easy as it sounds š Here are the steps … Read more
The following problem with webMethods Integration Server already occured twice in our environment, so I think it’s time to document the fix. When opening the generated WSD for a web service, I got the following error: [ISS.0088.9163] Could not retrieve WSDL for service […], WSD not found. The problem was the URL generated by the … Read more
During the startup of webMethods Integration Server I found quite a few entries like this in server.log: [ISS.0141.9998E] Exception –> [ISS.0141.9208] Could not deploy the Web service descriptor […]. Cause: [ISC.0081.9164] Exception occurred during generation of WSDL for service […]: [ISC.0124.9011] Document to XSD error: Simple type […] does not exist None of the mentioned … Read more
Changing the Java version under which webMethods Integration Server runs and compiles Java services is quite easy (after you searched for hours for the right files to change ;-)). You can check which version your Integration Server uses on the About page: Here’s how to change the version for Integration Server (in my case version … Read more
For quite some time now I have used the default names for all the different artifacts (set, build, map, candidate) in WmDeployer, because I simply did not know how to name them in a meaningful way: However, after talking to an SAG consultant today, I finally came up with a meaningful naming convention: Deployment Set: … Read more
