public void startElement(String uri, String localName, String qName,
Attributes attributes)
can anybody please give a simple example as to how localname is different from qName and what exactly is the uri string ? And yes before somebody asks I did check it on the net but no one cared to mention the difference as some examples used qName and others used localname which is really confusing for me.
ok i found the answer here http://www.saxproject.org/namespaces.html
and here What is the difference between localname and qname?

#AfterReturning(value = "anyPublicMethod() && applyPrivacy()", returning = "result")
public Object afterReturning(JoinPoint joinPoint, Object result) {
return someService.createNewObjectWithHelpOfResult(result);
}
My intention was to fill some null values in result fields. So in method createNewObjectWithHelpOfResult I'm creating a new Object and setting only the required values. But return value is not reflecting after afterReturning method is finished. But if I do mutations on result. They're very well reflected after aspect #AfterReturning method ends, but I want the return value to be used? Is this not possible? I'll have to do mutation only?
What #M.Deinum explained, is documented in the Spring manual, section "After Returning Advice". The end of the section reads:
Please note that it is not possible to return a totally different reference when using after returning advice.
Therefore, you cannot just make your #AfterReturning advice have a return type other than void and hope it will magically return something. As the advice type name implies, all 3 types of #After* advices run after the method has returned already. There is nothing you can do to change the result (except for altering internal state of an object instance). You can merely read (and e.g. log) it.
The solution, like #M.Deinum said, is an #Around advice, see also again the Spring manual.
It is generally a good idea to at least study the manual and learn some basics or take a look at examples before asking questions in public. I am sure you did not find any valid example for an #After* advice with non-void return type.
I am using #AfterReturning on the methods whose return type is String but instead of String I am getting null as result
#AfterReturning(value = "execution(* com.example.demo.aop.business..(..))", returning = "result")
public void afterA(JoinPoint joinPoint, Object result) {
log.info("After method {} returned with value {}", joinPoint, result);
}
O/P - After method execution(void com.example.demo.aop.business.Business2.disp()) returned with value null
I've created a very neat way of implementing a PATCH method for my Web.API project by making use of an ExpandoObject as a parameter. As illustrated below:
[HttpPatch, Route("api/employee/{id:int}")]
public IHttpActionResult Update(int id, [FromBody] ExpandoObject employee)
{
var source = Repository.FindEmployeeById(id);
Patch(employee, source);
Repository.SaveEmployee(source);
return Ok(source);
}
However, when generating documentation ApiExplorer is at a loss as to what to do with the ExpandoObject, which is totally understandable. Would anyone have any ideas on how to manipulate the ApiExplorer to provide some sensible documentation?
My idea was to maybe introduce an new attribute which points to the actual Type that is expected:
public IHttpActionResult Update(int id, [FromBody, Mimics(typeof(Employee))] ExpandoObject employee)
{
...
}
But I have no idea where to start, any ideas or suggestions are welcome.
So this has been the source of some late evenings in order to get the Api Explorer to play along with our developed Http Patch mechanism. Truth be told, I'd probably should do a bit of a proper write up to full explain the mechanics behind the whole idea. But for those of you who landed on this page because you want the Api explorer to use a different type in the documentation, this is where you need to look:
Open HelpPageConfigurationExtensions.cs and locate the following method:
//File: Areas/HelpPage/HelpPageConfigurationExtensions.cs
private static void GenerateRequestModelDescription(HelpPageApiModel apiModel, ModelDescriptionGenerator modelGenerator, HelpPageSampleGenerator sampleGenerator)
{
....
}
this is the location where the parameter information is available to you and also provides you with the ability to replace/substitute parameter information with something else. I ended up doing the following to handle my ExpandoObject parameter issue:
if (apiParameter.Source == ApiParameterSource.FromBody)
{
Type parameterType = apiParameter.ParameterDescriptor.ParameterType;
// do something different when dealing with parameters
// of type ExpandObject.
if (parameterType == typeof(ExpandoObject))
{
// if a request-type-attribute is defined, assume the parameter
// is the supposed to mimic the type defined.
var requestTypeAttribute = apiParameter.ParameterDescriptor.GetCustomAttributes<RequestTypeAttribute>().FirstOrDefault();
if (requestTypeAttribute != null)
{
parameterType = requestTypeAttribute.RequestType;
}
}
}
Just, note that the RequestTypeAttribute is something I devised. My WebApi endpoint looks like this now:
public IHttpActionResult Update(int id,
[FromBody, RequestType(typeof(Employee))] ExpandoObject employee)
Thank you to everyone who took time to look into the problem.
I am trying to use xpath in RFT. Searching over the net threw this code at me-
private static NodeList getNodesWithXPath(Document document, String xpathStr)
throws XPathExpressionException {
NodeList nodes = null;
XPathFactory factory = XPathFactory.newInstance();
XPath xpath = factory.newXPath();
if (xpathStr != null) {
XPathExpression expr = xpath.compile(xpathStr);
Object result = expr.evaluate(document, XPathConstants.NODESET);
nodes = (NodeList) result;
}
return nodes;
}
Now, I am new at RFT and totally at a loss about how to access the 'Document' object? Trying to typecast TestObject into this throws an exception. I could see a few examples stating something like
Document doc = parse(xmlFileLocation)
but I am not sure what this xmlFileLocation means. I have a simple web page where I need to identify the element using xpath.
P.S. - I understand there are other ways of identifying the object using atDescendant, etc, but I need to explicitly use xpath here due to some reasons.
Any help would be greatly appreciated.
Thanks!
They are different Document objects.
I think you got the code from IBM developerworks, and that is a document obtained from an XML file, thus browsable with XPATH.
RFT Document is com.rational.test.ft.object.interfaces.DocumentTestObject
while XML related one probably is org.w3c.dom.Document.
Totally different classes.
XPath is not supported by RFT and also no answers in the forums.
If you need XPath queries in your pages try something else, like Selenium.
Im creating an annotator called "NewAnnotator" and try to make it works in a pipeline with others annotators in ClearTK like:
SentenceAnnotator, PosTaggerAnnotator, etc. So I want to be able to run pipeline:
aggregate.add(SentenceAnnotator.getDescription());
aggregate.add(PosTaggerAnnotator.getDescription());
aggregate.add(NewAnnotator.getDescription());
// run the classification pipeline on the new texts
SimplePipeline.runPipeline(reader, aggregate.createAggregateDescription());
I wrote the code with no error, but when running it returns a lot of errors, which I think from this part in my NewAnnotator code:
public static AnalysisEngineDescription getDescription() throws ResourceInitializationException {
return AnalysisEngineFactory.createPrimitiveDescription(
NewAnnotator.class,
PARAM_POSTAG_MODEL_FILE,
ParamUtil.getParameterValue(PARAM_POSTAG_MODEL_FILE, "/somepath"));
}
public static final String PARAM_POSTAG_MODEL_FILE = ConfigurationParameterFactory.createConfigurationParameterName(
PosTaggerAnnotator.class,
"postagModelFile");
I almost copy this part from PosTaggerAnnotator, but it has no use in my NewAnnotator, I just add in so that I can use:
aggregate.add(NewAnnotator.getDescription());
because I don't know any other way to add to aggregate without .getDescription(); and I also don't know how to declare a correct getDescription() in my annotator, even it can works fine without it.
So please give me some advise here if you have experienced it! Thank you!
getDescription() is a convenience method to create a default description for your annotator. It uses AnalysisEngineFactory.createPrimitiveDescription(), to which you need to provide the right arguments, like this:
public static AnalysisEngineDescription getDescription() throws ResourceInitializationException {
return AnalysisEngineFactory.createPrimitiveDescription(
NewAnnotator.class,
first_parameter_name, first_parameter_value,
second_parameter_name, second_parameter_value,
... );
}
There are more examples in the uimaFIT codebase.
I am creating a custom SqlMembershipProvider class to add some enhanced functionality to the base class. I'm getting caught up on handling the connection string, though. How can I read the Connection String Name from the configuration and make that available to the rest of the methods?
Right now I have:
public override void Initialize(string name, NameValueCollection config)
{
base.Initialize(name, config);
_ConnectionStringName = config["connectionStringName"];
}
But in other methods, the _ConnectionStringName variable is null:
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings[_ConnectionStringName].ConnectionString)
What is the proper way to store the Connection String Name so it is available globally in my custom membership provider?
Thanks!
ProviderBase will throw a ConfigurationException if there are any entries left in the config collection by the time it get's it so each provider removes it's configuration entries before calling base.Initialize.
The issue, as you have found as a result of this answer is that you must get your values before calling base.Initialize.
Sorry, I missed that at first glance.
The rest of this post is historical and while technically correct misses the salient issue here as enumerated above.
First - try WebConfigurationManager.ConnectionStrings.
WebConfigurationManager handles applying the hierarchy of web.config all the way from your windows\microsoft.net\framework\2.0xxxx\web.config all the way up to your app.
This behaviour is not present in ConfigurationManager, which typically deals with machine.config to app.config.
If this does not solve your problem you must be overwriting the value elsewhere in your code, if indeed _ConnectionStringName is being properly assigned in Initialize.
First, set a breakpoint and ensure that _ConnectionStringName is being set as expected.
Then locate all references to the field and ensure that you do not have a bug.
This is assuming, of course, that _ConnectionStringName is a private field. If it is not, make it so and look for your compile error.
Not sure if this helps, but I was having a similar issue in needing to override the connectionstring in a sub-class of SqlMembershipProvider.
This idea is not my own - I found it in the comments section of this forum posting:
http://forums.asp.net/p/997608/2209437.aspx
public override void Initialize(string name, NameValueCollection config)
{
base.Initialize(name, config);<br>
string connectionString = //...what you want your connection string to be,
//so config["connectionStringName"]...
// Set private property of Membership provider.
System.Reflection.FieldInfo connectionStringField =
GetType().BaseType.GetField("_sqlConnectionString",
System.Reflection.BindingFlags.Instance
| System.Reflection.BindingFlags.NonPublic);
connectionStringField.SetValue(this, connectionString);
}
My apologies - I've never posted here before, so the formatting may be sub-par!
This is probably 6 months too late to help, but I was able to get the connection string this way:
using System.Web.Configuration;
Configuration config = WebConfigurationManager.OpenWebConfiguration("~");
MembershipSection section = config.SectionGroups["system.web"].Sections["membership"] as MembershipSection;
string defaultProvider = section.DefaultProvider;
string connstringName = section.Providers[defaultProvider].ElementInformation.Properties["connectionStringName"].Value.ToString();
string val = config.ConnectionStrings.ConnectionStrings[connstringName].ConnectionString;
This makes the assumption that the default provider has a connection string property - but if you're subclassing SqlMembershipProvider then should always have one, somewhere up the web.config chain (it's defined in the machine.config I believe).
All of this, to add one method to change the username.
