The following method returns a unique ID for this policy:
public String getID() {
return "WSDL_000001";
}
The following method returns the name that will be displayed to the user:
public String getName(Locale locale) {
return "Interoperable Web Services (WS-I)";
}
public String getDescription(Locale locale) {
return "Ensuring Interoperable Web Services - DEMO";
}
The following method returns the governor for the policy:
public PolicyGovernor getPolicyGovernor() {
return fGovernor;
}
You can use the following code to enter the logic that describes what to validate assets against when you use this custom policy:
public Result test() {
Result status = new Result(this)
You can use the policy context GetRAMAsset method and then the client APIs to gain access to all parts of an asset. The artifacts object is a list of all the artifacts in the asset:
RAMAsset asset = this.getPolicyContext().getRAMAsset(); RAMFolderArtifact folderArtifact = (RAMFolderArtifact)asset.getArtifactsRoot(); Artifact[] artifacts = folderArtifact.computeArtifactsAsFlatList(new NullProgressMonitor());
The following code validates the artifacts:
if (artifacts != null) {
validateArtifacts(status, artifacts);
}
if(status.getReturnCode() != ResultDetail.ERROR){
status.setMessage("You comply with the WS-I standards");
}
else{
status.setMessage("<font color=\"red\">You do not comply with the WS-I standards</font> To find out more check out our <a href=\"www.google.com\">corporate standard guidlines handbook.</a>");
}
return status;
}
