create and access web service with apache axis

[Prasanth Duggirala]

How can i access a webservices can any one send me a example i have URL "http://wsdds2.dz.decarta.com/openls/openls" which will accepts only xml formate and wich will recive xml formate can any one help on this. as soon as possible

[Ulf Dittmer]

Do you mean it receives SOAP requests, or just that it receives POST requests containing XML and that it returns XML? If the latter, you should be able to use the java.net.HttpUrlConnection class, an example of which can be found at http://www.exampledepot.com/egs/java.net/Post.html

[Prasanth Duggirala]

it will recive post request

[Prasanth Duggirala]

I want to access a web service and pass a request as a string and get the responce as a string.

can any one provide any example.

and then i want to convert the java class in web services file.

[Ulf Dittmer]

I want to access a web service

What kind of web service is this - SOAP? REST? Something else? What are its inputs and outputs?

i want to convert the java class in web services file.

I don't understand this. What is "the Java class"? What is a "web service file"?

[Prasanth Duggirala]

www.deCarta.com
The DDS Web Services provides an XML-over-HTTP service interface.
The service accepts XML for Location Services (XLS) requests and returns XLS.
The response from the DDS Web Services contains URLs for images, and XML elements representing addresses, routes, points of interest, and other structured information needed by a geospatial developer.

What I need to know?
Whether we can create a web service, which will be a middle tire which will have all functionality in the web service .
The inputs are xls out put is also xls.
How can we interact with web services.

[Ulf Dittmer]

I don't know what DDS is or does, but from what you describe it sounds more like it's not SOAP-based. So you'd probably be sending and receiving XML over an HTTP connection directly, much like the example I linked to above. I'm sure their site has information on how exactly to connect to it.

You'll probably want to use an API for creating and reading the XML; I've used XOM for that in the past.

hi

This the method i am taling about i got in deCarta site only,

public XLSMessage getGeoCode(String Countrycode,String Street,String BuildingNo,String Pincode) throws Exception{
try{
GeocodeRequest params = factory.createGeocodeRequest();
java.util.List addresses = params.getAddress();
addresses.add(newStructuredAddress(Countrycode,Street,BuildingNo,Pincode));

XLSMessage msg = newXLSMessage(params, "GeocodeRequest");

//show what gets sent to server
marshaller.marshal( msg, System.out );

//post to http server
XLSMessage resp = (XLSMessage) dataSource.executeRequest(msg);

//show what was returned from server
marshaller.marshal( resp, System.out );

return resp;

i want to create a web service to this method so it will work as middle tire.

but i am getting an error,
IWAB0489E Error when deploying Web service to Axis runtime
axis-admin failed with {http://xml.apache.org/axis/}HTTP (500)Internal Server Error
can you help me on this

[Peer Reynders]

The code that you are showing presumably is using deCarta's Java (J2SE) Client API that is part of their DDS Web Services product.

What is unclear is how Axis fits into the picture. Unless you are using the deCarta Client API inside one of your own Axis web services, use of the code you show in a client (consumer) should be unrelated to problems of deploying the producer web service.

[Prasanth Duggirala]

Hi IWAB0489E Error when deploying Web service to Axis runtime

do we need any extra jar files to be added in Tomcat or in the App

Below class is using some jars and for this class iam trying to create a webservice.

so that it will act as middle layer so that any one can access this method in the application so it will responce the GeoCode.

Can i use like this.Am i right to use like this any changes i have to make?

please help me on this.....

package com.deCarta.geoCode;
import com.telcontar.openls.xml.GeocodeRequest;
import com.telcontar.openls.xml.XLSMessage;


public class ReqGeoCode extends AbstractExample{
public String getGeoCode(String Countrycode,String Street,String BuildingNo,String Pincode) throws Exception{
try{
GeocodeRequest params = factory.createGeocodeRequest();
java.util.List addresses = params.getAddress();
addresses.add(newStructuredAddress(Countrycode,Street,BuildingNo,Pincode));
//System.out.println("------------------req");
XLSMessage msg = newXLSMessage(params, "GeocodeRequest");

//show what gets sent to server
marshaller.marshal( msg, System.out );

//post to http server
XLSMessage resp = (XLSMessage) dataSource.executeRequest(msg);
//System.out.println("------------------res");
//show what was returned from server
marshaller.marshal( resp, System.out );

Object obj=resp;
String response=obj.toString();

return response;
}finally{
super.close(); //release resources, in this case, the dataSource

It's hard to say what changes you need to make, because we don't know what that code is supposed to do, nor what it does right now. It's also very hard to read because you don't UseCodeTags; please go back and edit your post to use those.

You mentioned an error message - is there a stack trace to go with it? Where do you see this error, and what were you going when it happened? Is Axis otherwise installed correctly and happy?

hi iam getting the responce as a XML i want to unmarshal the xml how can i do that can any one give any examples....

Earlier you said:

Hi IWAB0489E Error when deploying Web service to Axis runtime
...

This suggested to me that you had already tested the JAXB unmarshalling code and that it was working fine and that the problems only occurred when you were trying to integrate/deploy the code.

Isolate the JAXB code into a small program, force feed it the response that you have and see what happens. Even better - use it to formulate a unit test.

Addendum:

You are already using the JAXB marshaller which is created when you compile the XML schema for creating the request - use the unmarshaller to read the response.

If you're going to use a DocumentBuilder with a document which uses namespaces, then you should really call setNamespaceAware(true) on the DocumentBuilderFactory that creates it.

However I'm not convinced you need to do any DOM-manipulating code. A plain old XSLT transformation might be better, as Peer suggests.

[Prasanth Duggirala]

I have a doubt trans.transform(makeXml(), result); this does printing in console i want to change into string and return the string how we can do?

If we do so then if we call the method then the return type is string we can get the value.

the given code will can we create the webservice like this i have a doubt..

can we get the pos value 40.874312 -74.006446

[Prasanth Duggirala]

Thanks All
Peer Reynders your Code Real helps me Thanks for Supporting me i am new to this webServices...........

I got the answer for above asked question by adding this shown below code.
i can get the value in string return type..

public String getGeoCode(String Countrycode,String Street,String BuildingNo,String Pincode) throws Exception{
GeocodeRequest params = factory.createGeocodeRequest();
java.util.List addresses = params.getAddress();
b = addresses.add(newStructuredAddress(Countrycode,Street,BuildingNo,Pincode));
XLSMessage msg = newXLSMessage(params, "GeocodeRequest");
//show what gets sent to server
marshaller.marshal( msg, System.out );
//post to http server
XLSMessage resp = (XLSMessage) dataSource.executeRequest(msg);
marshaller.marshal(resp, System.out);

StringWriter writer = new StringWriter();
StreamResult result = new StreamResult(writer);
//Writing to File
try {
FileOutputStream fout = new FileOutputStream("Responce.xml");
marshaller.marshal(resp, fout);
fout.close();
TransformerFactory factory = TransformerFactory.newInstance();
Transformer trans = factory.newTransformer(makeXslt());
trans.transform(makeXml(), result);
System.out.println(writer.toString());
}catch(Exception e){
e.printStackTrace();
}
return writer.toString();
}

Can i use this method as a webservice which internaly calling deCarta webservice.

if i can create which procedure is easy to using Axis or etc any Suggitions for me regarding this...

I tried to create webservice like this procedure link
http://www.eclipse.org/webtools/jst/components/ws/M3/tutorials/BottomUpWebService.html

iam getting this error
!-- IWAB0489E Error when deploying Web service to Axis runtime
axis-admin failed with {http://xml.apache.org/axis/}HTTP (500)Internal Server Error --!

In Server side error iam getting this
@-- org.apache.axis.deployment.wsdd.WSDDException: Must include type attribute for Handler deployment!
org.apache.axis.deployment.wsdd.WSDDException: Must include type attribute for Handler deployment! --@


then i canable to se one wsdl file created i tried to create a client for this then i got one more error
@-- org.apache.axis.utils.JavaUtils isAttachmentSupported
WARNING: Unable to find required classes (javax.activation.DataHandler and javax.mail.internet.MimeMultipart). Attachment support is disabled. --@

any suggitions please....

prasanth,
I am assuming you are using Eclipse 3.4

Do the following.
1. First decide on using Axis2 and install .WAR from axis 2 official site
2. Go to Axis2 download page and download Eclipse plugins at http://ws.apache.org/axis2/tools/index.html

3. If you haven't done, make sure you select the runtime web/app server in Eclipse ( windows- preference- server- runtime). It could be your tomcat/jboss

4. Similar to 3, select the web service Axis 2 runtime by selecting your Axis2 installation folder..

And finally in Project, right click - New - web service - web service client - then follow the steps and should work..

[Peer Reynders]

There is also no need to write the response xml to a file unless you are processing monster responses. You can simply use a java.io.ByteArrayOutputStream, i.e.

ByteArrayOutputStream bos            = new java.io.ByteArrayOutputStream();
marshaller.marshal(resp, bos);
 
TransformerFactory    factory        = TransformerFactory.newInstance();
Transformer           trans          = factory.newTransformer(getAddressXsltSource());
Source                responseSource = new StreamSource( new ByteArrayInputStream(bos.toByteArray()) )
trans.transform(responseSource, result);

I don't see any problem using the code inside of a web service. Exposing this method as a web method makes really no sense, as you are working with XML-based technologies - you are handing the client unstructured plain text data when you could be handing them semi-structured XML data. While you may not want to return the data in the OpenGIS format, you should at least define an XML structure (preferably defined with XML Schema) that makes it easy for the client to work with (e.g. by pulling out the interesting bits with XPath).

Now in a constrained mobile environment you need to carefully assess whether the overhead of SOAP web services is even worth it.
SOA Without SOAP: The Java ME Perspective

I'm getting a sudden sense of d�j� vu. Have a look at this topic.

any suggitions please....

Stop using WTP for building your web service, use the web service stack tools for a more "hands-on" approach. Once you get into trouble (which you obviously have gotten yourself into) it takes an awful lot of knowledge of the workings of Eclipse, WTP, ,Plugins and the web services stack to find out where these parts are not fully connecting (you can still edit any files in Eclipse).

Now if you need to use Axis 1 because you are limited to JAX-RPC (a more or less deprecated Java Web Services API) through J2ME Web Services(JSR-172) then Creating Web Services with Apache Axis is a good primer.

Just make sure that you understand the implications of contract first and contract last before you blindly start exposing your Java methods as web methods. (See also Starting Out and Webservice - WSDL or Java Class).

Switch to a more modern Java web service API if you can. JAX-WS is the current standard but it requires at least Java SE 5 and it is already included in Java SE 6. Look here for an utterly barebones example. Of course you will have to move to deploying JAX-WS under Tomcat.

If you are limited to J2SE 1.4 then Axis2 is supposed to work.

But ultimately you have to decide whether SOAP web services are the right solution for your particular problem.

i have created to access the decarta webservice.
ReqGeoCode.java which is obtaing some method from abstract class AbstractExample.java.

How can i create java to wsdl file for ReqGeoCode.java manually.

Will it takes the AbstractExample.java in the wsdl and all the jar required to handle the request and response.

Can we create a webservice which is optaining a deCarta web service.

how can we test the client whather the webservice is working.

which is easy way to create ReqGeoCode.java as a web method.

so i can use the getGeoCode(String Countrycode,String Street,String BuildingNo,String Pincode) and which it returns the string value.

[Peer Reynders]

Creating Web Services with Apache Axis should answer all your questions. However you are currently pursuing a much less than optimal path - your current solution will have to be replaced sooner than later.

Hi all thanks for your support on web services and special thanks for Peer Reynders realy help me and it works superbly Peer.
