| Methods Summary |
|---|
| public void | addResourceAdapter(java.lang.String rarName, java.lang.String moduleDir)Adds the requested resource adapter to the ConnectorClassLoader. A
ConnectorClassLoader is created with the moduleDir as its search path
and this classloader is added to the classloader chain.
try {
//System RARs are placed in classpath and hence would be handled
//by the parent classloader
if(!ResourcesUtil.createInstance().belongToSystemRar(rarName)) {
File file= new File(moduleDir);
EJBClassLoader cl= new EJBClassLoader(parent);
cl.appendURL(file.toURI().toURL());
classLoaderChain.add(cl);
rarModuleClassLoaders.put(rarName, cl);
}
} catch (MalformedURLException ex) {
_logger.log(
Level.SEVERE,
"enterprise_util.connector_malformed_url",
ex);
}
|
| public java.lang.String | getClasspath()Returns all the resources of the connector classloaders in the chain,
concatenated to a classpath string.
Notice that this method is called by the setClassPath() method of
org.apache.catalina.loader.WebappLoader, since the ConnectorClassLoader does
not extend off of URLClassLoader.
StringBuffer strBuf = new StringBuffer();
for (int i = 0; i < classLoaderChain.size(); i++) {
EJBClassLoader ecl= (EJBClassLoader) classLoaderChain.get(i);
String eclClasspath = ecl.getClasspath();
if ( eclClasspath != null) {
if (i > 0) strBuf.append(File.pathSeparator);
strBuf.append(eclClasspath);
}
}
return strBuf.toString();

| public void | removeResourceAdapter(java.lang.String moduleName)Removes the resource adapter's class loader from the classloader linked
list
