[JBossCache] - Problem reading (deserializing) objects from FileCacheLoader
by arjan
Hi,
I can't seem to get it working.. I'm running JBossCache on a default JBoss4.0.5 installation (JDK 1.5). I've configured JBossCache as a service (deploy/treecache-service.xml). For each deployed webapp a separate ClassLoader is instantiated, so I have to register a ClassLoader for a section of the TreeCache (see below).
The problem is that once objects are serialized to the file cache, they can't be de-serialized (unmarshalled).
I'm getting stack traces like this:
| java.lang.ClassNotFoundException: No ClassLoaders found for: nl.yirdis.monet.chart.ChartMetadata

|
In my treecache configuration I've enabled RegionBasedMarshalling and InactiveOnStartup, as described in the user guide:
| <attribute name="UseRegionBasedMarshalling">true</attribute>
| <attribute name="InactiveOnStartup">true</attribute>
|
The region is configured like this:
| <region name="/nl/yirdis/monet/charts">
| <attribute name="maxNodes">1000</attribute>
| <attribute name="timeToLiveSeconds">86400</attribute>
| <attribute name="maxAgeSeconds">86400</attribute>
| </region>
|
In my code (using Spring), I've set the ClassLoader for that region to the Classloader of the webapp:
| public void afterPropertiesSet() throws Exception {
| treeCache.registerClassLoader("/nl/yirdis/monet/charts/", ChartMetadata.class.getClassLoader());
| treeCache.activateRegion("/nl/yirdis/monet/charts/");
| }
|
(ChartMetadata is a class containing the serialized stuff. It implements the Serializable interface).
Deactivation on undeployment of the webapp is done likewise, as stated in the docs.
Where did I go wrong? What's causing the TreeCache (FileCacheLoader) to cause class loading errors?
Regards,
Arjan

[JBossWS] - Unable to load Provider
by burakbayramli
I have problems running the sample Web Service shown in Quick Start document.
I am able to deploy the Web Service, no problem, I see it running at http://localhost:8080/jbossws/services. Then, I generate stubs using wsconsume. I place the generated code to a different package called org.bilgidata.kitapdemo.service.ws.
I am on JBoss 4.2.1.GA and jbossws-2.0.
I used the following code:
import javax.xml.bind.annotation.XmlAccessType;
| import javax.xml.bind.annotation.XmlAccessorType;
| import javax.xml.bind.annotation.XmlType;
|
| import org.bilgidata.kitapdemo.pojo.Car;
|
| @XmlAccessorType(XmlAccessType.FIELD)
| @XmlType(
| name = "discountRequest",
| namespace="http://org.bilgidata.kitapdemo.service",
| propOrder = { "car" }
| )
| public class DiscountRequest {
|
| public DiscountRequest() { }
|
| public DiscountRequest(Car car) {
| this.car = car;
| }
|
| protected Car car;
|
| public Car getCar() {
| return car;
| }
|
| public void setCar(Car value) {
| this.car = value;
| }
|
| }
|
@Stateless
| @WebService(
| name="ProfileMgmt",
| targetNamespace = "http://org.bilgidata.kitapdemo.service",
| serviceName = "ProfileMgmtService"
| )
| @SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE)
| public class ProfileMgmtBean {
|
| @WebMethod
| public String getCustomerDiscount(DiscountRequest request) {
| return "--";
| }
| }
|
import org.bilgidata.kitapdemo.service.ws.*;
|
| public class Mainline {
|
| public static void main(String[] args) throws Exception {
|
| ProfileMgmtService profileMgmt = new ProfileMgmtService();
|
| String s = profileMgmt.getCustomerDiscount(new DiscountRequest());
|
| }
|
| }
|
The error I get is:
