How to get a service bean inside a custom tag library class in Grails 3

I want to get a service bean from the application context inside my custom tag library. The service name i will get it from the custom tag attribute.
This is the code i previously used.
class CustomTagLib {
static defaultEncodeAs = [taglib:'html']
//static encodeAsForTags = [tagName: [taglib:'html'], otherTagName: [taglib:'none']]
def selectList = { attrs ->
try{
String servName=attrs.service
String servMethod=attrs.method
ApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(session.getServletContext())
def myservice=ctx."${servName}"
attrs.from = myservice.invokeMethod(servMethod,null);
out << g.select( attrs )
}catch(Exception e){
println("Exception in CustomTagLib in method selectList:"+e)
}
}
}
This code is worked me for Grails 2.3 version but not for version 3.
Please help me to find out a solution.

Try the following:
import grails.util.Holders
def myservice = Holders.getApplicationContext().getBean( servName )
Where servName would be your service name with lowercase first letter & camel case for the remainder

Can't call soap metod from SoapEngine to Java Soap WebService

I have a problem with me web service which I created in Java. This web service is to send data to my mobile application created in Swift.
For now I just want to test communication between application and WebService, so I create one simple method which returns a string.
My WebService:
#WebService(serviceName = "mSetiWebService", targetNamespace = "http://javawebservices.dawidratajczak.pl")
#SOAPBinding(style = Style.DOCUMENT, use = Use.LITERAL, parameterStyle = ParameterStyle.WRAPPED)
public class mSetiWebService {
#WebMethod(operationName = "getMyOtherStuff", action="getMyOtherStuffAction")
public String getMyOtherStuff() {
return "Hello from WebService !";
}
}
The java package(namespace) name is pl.dawidratajczak.webservices. I test this WebService by Boomerang Plugin for chrome and it works fine. But when I use SOAPEngine for Swift a get an error.
My Swift code:
let soap = SOAPEngine()
soap.userAgent = "SOAPEngine"
soap.actionNamespaceSlash = true
soap.version = SOAPVersion.VERSION_1_1
soap.responseHeader = true // use only for non standard MS-SOAP service
soap.requestURL("http://localhost:8080/mSetiSoapService/mSetiWebService",
soapAction: "getMyOtherStuff",
completeWithDictionary: { (statusCode : Int,
dict : [NSObject : AnyObject]!) -> Void in
let result:Dictionary = dict as Dictionary
NSLog("%#", result)
}) { (error : NSError!) -> Void in
NSLog("%#", error)
}
The error is simple: (I change . in address to _)
SOAPEngine Server response: Unexpected wrapper element getMyOtherStuff found. Expected {[httpjavawebservices_dawidratajczak_pl}getMyOtherStuff.
2016-08-26 20:24:59.835 SETI Mobile[4658:200526] Error Domain=NSOSStatusErrorDomain Code=0 "Unexpected wrapper element getMyOtherStuff found. Expected {http://javawebservices_dawidratajczak_pl}getMyOtherStuff." UserInfo={NSLocalizedDescription=Unexpected wrapper element getMyOtherStuff found. Expected {javawebservices_dawidratajczak_pl}getMyOtherStuff.}**
When I put the soapAction like the error expect {url}getMyOtherStuff I get another error that character { is unrecognized. At the end when I put all url and soapActionme function is not found.
What I do wrong?

Transforming JSON body using WSO2 class mediator

Following is the log of my current json body. And I want to add new property to this body. "NewPropertyName": "value". Since the value is in a database I am using a class mediator to add this property.
[2015-05-18 05:47:08,730] INFO - LogMediator To: /a/create-project, MessageID: urn:uuid:b7b6efa6-5fff-49be-a94a-320cee1d4406, Direction: request, _______BODY_______ =
{
"token": "abc123",
"usertype":"ext",
"request": "create"
}
Class mediator's mediate method,
public boolean mediate(MessageContext mc) {
mc.setProperty("key", "vale retrived from db");
return true;
}
but this doesn't work as I expected. I couldn't find any guide to add property to json body using class mediator, please help.

To inject a property to the body you have to use following code snippet,
JsonUtil.newJsonPayload(
((Axis2MessageContext) context).getAxis2MessageContext(),
transformedJson, true, true);
inside a class mediator. Following is an example of mediate method.
/**
* Mediate overridden method to set the token property.
*/#Override
public boolean mediate(MessageContext context) {
try {
// Getting the json payload to string
String jsonPayloadToString = JsonUtil.jsonPayloadToString(((Axis2MessageContext) context)
.getAxis2MessageContext());
// Make a json object
JSONObject jsonBody = new JSONObject(jsonPayloadToString);
// Adding the name:nameParam.
jsonBody.put("name", getNameParam());
String transformedJson = jsonBody.toString();
// Setting the new json payload.
JsonUtil.newJsonPayload(
((Axis2MessageContext) context).getAxis2MessageContext(),
transformedJson, true, true);
System.out.println("Transformed JSON body:\n" + transformedJson);
} catch (Exception e) {
System.err.println("Error occurred: " + e);
return false;
}
return true;
}
You will need json and other libraries for this. This is fully explained in following blog post.
json-support-for-wso2-esb-class-mediator

mc.setProperty is used to create a new property as if you were using property mediator.
If you want to add a new element inside your message, in java, you can handle it as if it were a XML message (for exemple, to get the first element :
OMElement element = (OMElement) context.getEnvelope().getBody().getFirstOMChild(); )
Sample to add a new element with a javascript :
<script language="js"><![CDATA[
var payloadXML = mc.getPayloadXML();
payloadXML.appendChild(new XML(<NewPropertyName>value</NewPropertyName>));
mc.setPayloadXML(payloadXML);
]]></script>
Log the message in XML with <log level="full"> and you get :
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<jsonObject>
<token>abc123</token>
<usertype>ext</usertype>
<request>create</request>
<NewPropertyName>value</NewPropertyName>
</jsonObject>
</soapenv:Body>
</soapenv:Envelope>
Log the message in JSON with
<log>
<property name="JSON-Payload" expression="json-eval($.)"/>
</log>
and you get :
JSON-Payload = {"token":"abc123","usertype":"ext","request":"create","NewPropertyName":"value"}

Jersey getting template path

Im using Jersey 2 and I want to get the URI template.
The reason is that Im creating an auth system that validates based on the URI. I managed to work:
#Override
public void filter(ContainerRequestContext containerRequest) throws IOException {
String method = containerRequest.getMethod();
String uri = containerRequest.getUriInfo().getPath();
}
The problem is that getPath returns something like:
/companies/1
And I want it to return
/companies/{id}
Which is how I declared with:
#Path("{id}")
thank you
EDIT I thought I found it here:
#Context
private ExtendedUriInfo uriInfo;
//...
Resource matchedModelResource = uriInfo.getMatchedModelResource();
System.out.println(matchedModelResource.getPathPattern().getTemplate().getTemplate());
buut guess what? matchedModelResource is null.
Also, this:
List<UriTemplate> matchedTemplates = uriInfo.getMatchedTemplates();
Returns an Empty List of UriTemplate. :(
Why are the data not beeing set?

Ok. So the answer is to use:
uriInfo.getMatchedTemplates();
Where uriInfo is actually ExtendedUriInfo.
This is the code I've made to get the correct syntax:
List<UriTemplate> matchedTemplates = uriInfo.getMatchedTemplates();
StringBuilder builder = new StringBuilder();
for (int i = matchedTemplates.size() - 1; i >= 0; i--) {
builder.append(matchedTemplates.get(i).getTemplate().substring(1));
}
System.out.println("Permission is: " + builder.toString());
// Prints:
// Permission is: sig/companies/{id}
The reason the data was null or empty before is because I had an #PreMatching annotation in my filter class. Please dont ask why.
Hope this helps someone.

Is it possible to get the absolute request url without path parameters

I am trying to get the request url without values of path parameters into it.
Consider my complete url is
URl: http://localhost:8080/aaa/mock/abcd/1234/true
Path parameters: abcd, true
Output needed: /aaa/mock/abcd
My web service method looks like this.
#Path(value = "/aaa/mock")
#Component
public class MockService
{
private static Log log = LogFactory.getLog(MockService.class);
//address
#GET
#Path(value = "/{mockrequest}/{status}")
#Produces(MediaType.JSON)
public String mockEngagement(#Context ContainerRequestContext request,#PathParam("mockrequest") String mockrequest,#PathParam("status") String status )
{
log.info("The mock url is"+request.getUriInfo().getRequestUri());
log.info("The mock url is"+request.getUriInfo().getAbsolutePath());
log.info("The mock url is"+request.getUriInfo().getBaseUri());
log.info("The mock url is"+request.getUriInfo().getMatchedURIs());
**//Out put needed /aaa/mock/abcd**
return "ajaja";
}
}
None of the above calls return the required info.
I am thinking if there is a generic process to get the desired output irrespective of number of path parameters.
Any such methods.

Try UriInfo#getPath(), UriInfo#getPath(boolean), or UriInfo#getPathSegments(). The boolean argument is whether the path should be encoded or not.
https://jersey.java.net/apidocs/2.3.1/jersey/index.html
You could also get the absolute path and the base path and then use URI#relativize(URI).

Try this:
request.getUriInfo().getPathSegments().get(0).getPath()

public void filter(ContainerRequestContext context) throws IOException {
Message message = PhaseInterceptorChain.getCurrentMessage();
Set<Map.Entry<String, Object>> o = (Set<Map.Entry<String, Object>>)message.entrySet();
for (Map.Entry<String, Object> oo : o) {
String key = oo.getKey();
Object val = oo.getValue();
// Thises two properties gives the path of web service
//path_to_match_slash
//org.apache.cxf.request.uri
if(key.equals("path_to_match_slash"))
{ String v = (String)val;
System.out.println (key);
System.out.println (v);
}
if(key.equals("org.apache.cxf.request.uri"))
{ String v = (String)val;
System.out.println (key);
System.out.println (v);
}
}
}
this code could work only for apache cxf rest
we can found path_to_match_slash , org.apache.cxf.request.uri properties in the ContainerRequestContext
