Hi,
you've missunderstood the concept of a context classloader.
A documentation bug [1] is open since a long time. Setting the context
classloader doesn't mean that all classes created from that point on are
created through this classloader. See here [2] and [3] for more information.

Hi
I am trying to create a maven plugin to jboss wsconsume, but I have a problem
with classloader in plugin.
My plugin is based in an ant task (WSConsumeTask).
I am using maven 2.0.8 on Windows machine.
When I created a simple Java project with libraries necessary, my code works.
How shown below:
public static void main(String[] args) {
WSConsumeTask t = new WSConsumeTask();
t.setWsdl("https://xxx/crypto?wsdl";);
t.setVerbose(true);
t.setKeep(true);
t.execute();
}
But when I am using into maven plugin, I got problem with classloader.
I got this exception:
C:\eclipse\workspace\TestePluginMaven\output\com\buscape\bean\CryptoService.java:7:
cannot find symbol
symbol : class Service
location: package javax.xml.ws
import javax.xml.ws.Service;
^
C:\eclipse\workspace\TestePluginMaven\output\com\buscape\bean\CryptoService.java:8:
cannot find symbol
symbol : class WebEndpoint
location: package javax.xml.ws
import javax.xml.ws.WebEndpoint;
^
C:\eclipse\workspace\TestePluginMaven\output\com\buscape\bean\CryptoService.java:9:
cannot find symbol
symbol : class WebServiceClient
location: package javax.xml.ws
import javax.xml.ws.WebServiceClient;
The plugin classloader doesn´t load the jaxws libraries. But this libraries was
added in pom.xml of plugin.
I tried to add dependencies tag in my plugin config, but didn´t works. How
shown below:
<plugin>
<groupId>jboss</groupId>
<artifactId>maven-jbossws-plugin</artifactId>
<version>1.0.0</version>
<configuration>
<verbose>true</verbose>
<keep>true</keep>
<wsdl>https://xxx/crypto?wsdl</wsdl>
</configuration>
<dependencies>
<dependency>
<groupId>jboss.jbossws</groupId>
<artifactId>jaxws-tools</artifactId>
<version>3.0.1-native-2.0.4.GA</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>jboss.jbossws</groupId>
<artifactId>jboss-jaxws</artifactId>
<version>3.0.1-native-2.0.4.GA</version>
<scope>compile</scope>
</dependency>
</dependencies>
</plugin>
I tried too to use an initClassLoader based in jaxws-maven-plugin source, how
shown below:
private String initClassLoader(ClassLoader parent) throws
MojoExecutionException {
try {
List classpathFiles =
project.getCompileClasspathElements();
URL[] urls = new URL[classpathFiles.size() + 4];
StringBuffer classPath = new StringBuffer();
for (int i = 0; i < classpathFiles.size(); ++i) {
getLog().debug((String)classpathFiles.get(i));
urls[i] = new
File((String)classpathFiles.get(i)).toURL();
classPath.append((String)classpathFiles.get(i));
classPath.append(File.pathSeparatorChar);
}
urls[classpathFiles.size()] = new
File(project.getBuild().getOutputDirectory()).toURL();
urls[classpathFiles.size() + 1] =
getArtifact("jboss.jbossws:jboss-jaxws");
urls[classpathFiles.size() + 2] =
getArtifact("jboss.jbossws:jaxws-tools");
File toolsJar = new
File(System.getProperty("java.home"),"../lib/tools.jar");
if (!toolsJar.exists()) {
toolsJar = new
File(System.getProperty("java.home"),"lib/tools.jar");
}
urls[classpathFiles.size() + 3] = toolsJar.toURL();
System.out.println("urls: "+Arrays.toString(urls));
URLClassLoader cl = new URLClassLoader(urls,parent);
// Set the new classloader
Thread.currentThread().setContextClassLoader(cl);
System.setProperty("java.class.path",classPath.toString());
String sysCp = System.getProperty("java.class.path");
return sysCp;
}
catch (MalformedURLException e) {
throw new MojoExecutionException(e.getMessage(),e);
}
catch (DependencyResolutionRequiredException e) {
throw new MojoExecutionException(e.getMessage(),e);
}
}
public void execute() throws MojoExecutionException {
// Need to build a URLClassloader since Maven removed it form
the chain
ClassLoader parent = this.getClass().getClassLoader();
String originalSystemClasspath = this.initClassLoader( parent );
try {
// Execute WSConsumeTask
WSConsumeTask t = new WSConsumeTask();
t.setWsdl(wsdl);
t.setVerbose(verbose);
t.setKeep(keep);
t.execute();
}
finally {
// Set back the old classloader
Thread.currentThread().setContextClassLoader(parent);
System.setProperty("java.class.path",originalSystemClasspath);
}
}
But, it doesn´t works.
Please, can someone help me?
Thanks
