[JBossWS] - Re: Newbee Q: Returning hashmaps
by mikkus
toString() outputs the contents of the HashMap only if the class generated is actually a HashMap, otherwise it outputs the java class instance name.
Most probably, wsconsume generated a class named HashMap, instead of using java.util.HashMap. This class is not actually a hashmap but a representation of the web service return data. Most probably, you'll need to convert that data to an actual hashmap.
I notice you commented out the cast to java.util.HashMap, probably you got a ClassCastException here? Seeing the class generated by wsconsume and related wsdl would help.
Your web.xml file should not be the problem. It just exposes the webservice, and since you're able to invoke it, it is doing its job.

[JBossWS] - Newbee Q: Returning hashmaps
by soch
I am trying to take the simple echo example (http://jbws.dyndns.org/mediawiki/index.php?title=JBossWS_JAX-WS_Tools) to the next level and running into problem.
I want to return a hashmap instead of the string.
Instead of the client printing the hasmap contents it prints the address of the the hashmap.
I am using the new tools: wsconsume, wsprovide & wsrunclient.
Here's the code:
GetPM.java:
=========
package getpm;
|
| import java.util.HashMap;
|
| @javax.jws.WebService
| public class GetPM
| {
|
| HashMap map = new HashMap();
|
| public HashMap getPM()
| {
| map.put("key1", "value1");
| map.put("key2", "value2");
| map.put("key3", "value3");
| System.out.println("From Server:" + map.toString());
| return map;
| }
| }
I am using the same web.xml as in the echo example -- is this were I am going wrong?
web.xml
=======
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
| xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
| xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
| version="2.4">
|
| <servlet>
| <servlet-name>GetPM</servlet-name>
| <servlet-class>getpm.GetPM</servlet-class>
| </servlet>
|
| <servlet-mapping>
| <servlet-name>GetPM</servlet-name>
| <url-pattern>/GetPM</url-pattern>
| </servlet-mapping>
| </web-app>
I created the getpm.war file & deployed it on the jboss AS.
Using wsconsume created the client files using the online version of service wsdl file: wsconsume -k http://localhost:8080/getpm/GetPM?wsdl
The client then calls the service using the following
GetPMclient.java:
=============
import getpm.*;
|
| public class GetPMclient
| {
| public static void main(String args[])
| {
| GetPMService service = new GetPMService();
| GetPM pm = service.getGetPMPort();
| System.out.println("Server said: " + pm.getPM());
|
| //HashMap hm = (HashMap) pm.getPM();
| //System.out.println(hm.toString());
| }
| }
On the server stdout I get the hashmap printed correctly, but on the client side instead of the hashmap I get the reference of the hashmap as below:
getpm.HashMap@1a0b53e
instead of
{key1=value1, key2=value2, key3=value3}
C:\....\webservices\getpm\client\output>wsrunclient GetPMclient
log4j:WARN No appenders could be found for logger (org.jboss.ws.metadata.builder.jaxws.JAXWSWebServiceMetaDataBuilder).
log4j:WARN Please initialize the log4j system properly.
Server said:
getpm.HashMap@1a0b53e

[JBossWS] - Re: Cannot expose EJB 3 as WS
by peiguo
Hm... After I read your reply, I tried two things but both failed, not sure what we did differently (I am using 4.2.2.GA).
1) I removed the config.xml file, when I deploy I got this:
| 15:07:45,192 ERROR [URLDeploymentScanner] Incomplete Deployment listing:
|
| --- Packages waiting for a deployer ---
| org.jboss.deployment.DeploymentInfo@9f91cc6f { url=file:/C:/jboss-4.2.2.GA/serve

| altDD: null
| lastDeployed: 1209420465192
| lastModified: 1209420465192
| mbeans:
|
2) the config.xml is still removed like option, but I added wsdlLocation in my code like this:
| @Stateless
| @WebService(endpointInterface="org.jboss.tutorial.webservice.bean.Calculator", wsdlLocation="http://localhost:8080/tutorial/CalculatorBean?wsdl")
|
And I got this:
| 15:10:27,020 ERROR [MainDeployer] Could not start deployment: file:/C:/jboss-4.2
