ClassCastException on classLoader
Hi everybody,
I'm having a bit of a problem with some reflection code and I can't work it out.
I have a method which get as as one of its parameters a class that implements an interface where resides the method I'm interested in to execute, something like
public void theMethod(Class<? extends InterfaceType> c) {
InterfaceType it = null;
try {
it = (InterfaceType) c.getClassLoader();
it.desiredMethod(String param);
} catch (Exception e) {
e.printStackTrace();
}But at the ip = (InterfaceType) c.getClassLoader(); i get the following exception
java.lang.ClassCastException: java.net.FactoryURLClassLoader
Any help is help, thanks in advance.
Joking aside, are you perhaps looking for
InterfaceType it = c.newInstance();
it.desiredMethod( param );?

ClassCastException with ClassLoader issues
I'm using JBoss 3.2.3, with Kodo 3.1.0
After doing a hot deploy in JBoss, ClassCastExceptions start occuring.
String filter = "reference==param1";
Extent extent = pm.getExtent(Customer.class, false);
KodoQuery query = (KodoQuery) pm.newQuery(extent, filter);
Collection col = null;
try {
query.declareParameters("String param1");
col = (Collection) query.execute("x34c");
if (col.isEmpty())
return null;
Customer cust = (Customer) col.iterator().next();
finally {
if (query != null)
query.close(col);
At the line: Customer cust = (Customer) col.iterator().next();
a ClassCastException is thrown. The class loader for Customer.class point
to the deployed ear file, whilst the loader for
col.iterator().next().getClass() points to null.
Now, what is even more interesting is if I amend the above code slightly:
Extent extent = pm.getExtent(Customer.class, false);
KodoQuery query = (KodoQuery) pm.newQuery(extent);
Collection col = null;
try {
col = (Collection) query.execute();
if (col.isEmpty())
return null;
Customer cust = (Customer) col.iterator().next();
finally {
if (query != null)
query.close(col);
With the above, everything works fine. The only difference is that one
uses a filter to retrieve a particular object from the datastore, and the
other retrieves all objects from the datastore. I don't understand why it
throws a ClassCastException in one instance and not the other. Note that
this only happens after a hot deploy.
This problem only surfaced recently after I added a few more classes to be
persistent capable. After adding a further two classes, the
ClassCastException moved to another class.
Can anyone explain this?

Did you make absolutely sure that you enhanced all of the new classes
and deployed them to correctly, and that you have clobbered any caches
JBoss may have to any of the old .ear files?
It might be the case that when you obtain the first in the list of all
the Customer instances, it doesn't have a relation to one of the new
classes, or its concrete instance is not one of the new classes, as
opposed to when you execute the filter.
If this doesn't help, can you provide us with some more information? At
a minimum, a complete stack trace is usually a prerequisite for being
able to diagnose problems like this.

HELP!! ClassCastException with custom module classloader hierarchy and redeployment
Hi,
I am defining custom module classloader hierarchy to avoid redeploying of the
entire application mainly because we have so many EJBs and it takes a long time
to deploy the entire app. I deploy my app using the exploded directory, add a
new method to an EJB in my dal.jar, redeploy, run my unittest and I get ClassCastException.
I am using weblogic.Deployer utility to reploy my module using "-targets dal.jar@accsserver"
argument. I even tried undeploying that module and redeploy again with no luck.
here is weblogic-application.xml definition of the custom class loader
<classloader-structure>
<module-ref>
<module-uri>floghmi.war</module-uri>
</module-ref>
<module-ref>
<module-uri>cts.jar</module-uri>
</module-ref>
<module-ref>
<module-uri>fdbs.jar</module-uri>
</module-ref>
<classloader-structure>
<module-ref>
<module-uri>dml.jar</module-uri>
</module-ref>
<classloader-structure>
<module-ref>
<module-uri>dal.jar</module-uri>
</module-ref>
</classloader-structure>
</classloader-structure>
</classloader-structure>
thanks,
NasrinRob,
regarding your question on redeploying the whole app without the classloader
structure, yes, that works fine. If I change a class and redeploy the whole app,
things are ok. However, when I speocify the classloader structure, and try to
redeploy the dal.jar, I get ClassClasException.
You are right about dml.jar being in a separate classloader. I have changed my
structure after I posted my question to load dml.jar from the application classloader.
So Rob, is there a bug in Weblogic 8.1 that causes this exception?
please let me know, I am anxiously waiting your response.
thanks,
Nasrin

Rob,
if I remove my classloader structure from weblogic-application.xml,I get an
error during redeployment, saying "You must include all of<list ofmy module names
here> in your files list to modify <dal.jar>. Yes, the server enforces constraints on partial redeployments. You must
deploy all the modules in a given classloader and any modules in child
classloaders.
Just to make sure, if you initially deploy your app, or redeploy the
whole thing, it works fine without the classloader-structure, right?
The problem I am trying to solve is to minimize our deployment time.Our application
has over 700 CMP 2.0 entity beans and 200 session beans. Our applicationdeployment
follows the J2EE layer architecture. The data mapping layer which consistof 700
entity beans are located in dml.jar. The data access layer which consistof 200
session beans are located in dal.jar. We create our ear with thesetwo jar files
plus some other framework jars and deploy on bea weblogic 8.1 SP2 andthat takes
about an hour. I need to be able to modify a session bean, i.e. changethe implementation
of a session bean or add a new method to a session bean interface andredeploy
only data access layer, the dal.jar, not the entity beans. This explainswhy you
see dml.jar in a classloader with a child classloader that loads dal.jar.
I included the ClassCastException from weblogic server console below.What is
happening is that I have a session bean with 6 methods that just doesa println.
I deploy my session bean, ExerciseSessionBeanFactory, and run my unittest that
invokes test1 through test6 methods. I modify my bean to add "test7"method and
redeply dal.jar successfully. I run my unit test that invokes test1through test7
methods and then I get a ClassCastException.
I hope this helps. Please let me know if you need more details.If you push dml.jar into a subloader, that means you can change dml.jar
without touching anything in the parent loader. However, it also means
that you've isolated it's classes and other modules can't see them.

ClassCastException caused by classloading
Hi,
I am using JDeveloper 10g and JDK 1.4.2_04. I have web application that uses EJBs. When I start the application locally in OC4J and try to invoke an XML transformation (that i need in order to generate pdf or other kind of document) I am receiving:
java.lang.ClassCastException at javax.xml.transform.TransformerFactory.newInstance(TransformerFactory.java:94) at bg.vies.business.artifactexport.service.transformer.impl.XMLArtifactTransformer.getTransformerFactory(XMLArtifactTransformer.java:153) at bg.vies.business.artifactexport.service.transformer.impl.XMLArtifactTransformer.applyTransformation(XMLArtifactTransformer......
......etc.
This was working fine till someone added in the project the following libs:
OracleHelpWeb, Oracle XML Parser v2, ADF UIX Runtime, ADF Controller Runtime. I know that OracleHelpWeb, Oracle XML Parser v2 contain a lib xmlparserv2.jar that contains javax.xml.transform.TransformerFactory class( For ADF UIX Runtime, ADF Controller Runtime I am not sure that they interfer over my case.). javax.xml.transform.TransformerFactory is also available in JDK 1.4.2_04 that I am using.
My question is how to make available javax.xml.transform.TransformerFactory only at one place where all parent classloaders will load it from there?
Thank you!I found the class loading white paper
http://www.oracle.com/technology/tech/java/oc4j/pdf/ClassLoadingInOC4J_WP.pdf
useful.
Essentially, you can use the ear file with the common jars and then combine it with class-path in your ejb manifests for example to share common jars
or
you can perhaps use the shared library mechanism outlined in the paper. But definitely read the paper (takes 30-45 minutes) but worth every minute of your time. I found this paper to be one of the best papers on class loading. It is critical for every J2ee developer to know this... -
ClassLoader and ClassCastException
ok, I have a Class named 'Lib' that I want to Load into the virtual machine from a file. I do this by extending ClassLoader and overloading the findClass() method to read the .class file through a FileInputStream.
Everything is fine until I try casting the 'Lib' object to a 'Lib' type. For example, I can do a
Object o = loadClass("Lib").newInstance();
but I cannot do a
Lib l = (Lib)loadClass("Lib").newInstance();
This also raises a new question: if you load a class dynamically during the execution of the program, how do you assign it to a new reference type so that you can use it?(i.e how do you make the 'Lib' type if you don't import the class? Incidently, I do import it and it still won't cast the object.)
I am making sure that the same class loader is loading all instances of the 'Lib' type, namely my(the extended) classloader, but it still won't let me cast. can anyone help??? thx.
KarlThanks for the comment Vlad. Here is the code I'm using, I verified that it is not being loaded by the bootstrap ClassLoader(default) as I moved it entirely out of the CLASSPATH.
Class myClass extens ClassLoader{
public void libInit(){
try{
System.out.println("parent class loader: " + ClassLoader.getSystemClassLoader().toString());
ClassLoader c = this.getClass().getClassLoader();
System.out.println("this class loader: " + c.toString());
Lib lib = (Lib)loadClass("Lib").newInstance();
System.out.println("asserting Lib instance. " + lib.toString());
}catch(Exception e){
System.err.println("error2: " + e.toString() + " " + e.getMessage());
public Class findClass(String name){
System.out.println("using my findClass()");
byte[] b = loadClassData(name);
return defineClass("Lib", b, 0, b.length);
final Class findLoadedClasses(String name){
return null;
byte[] b = null;
try{
File f = new File("Libs","Lib.class");
FileInputStream fis = new FileInputStream(f);
int i = (int)f.length();
b = new byte;
System.out.println("boo " + i);
fis.read(b,0,i);
fis.close();
}catch(Exception e){
// Logger code goes here
System.err.println("error1: " + e.getMessage());
return b;
The above fails on the cast from the newInstance() method. In the above code is the first place in the program where I even reference a 'Lib' type.
Also, instead of using a 'Lib' type, how could I read a class file into a reference type? Is this what java.lang.ref is for? thanks.

Problem with ClassCastException in web application
Hello,
I'm trying to deploy a web application in WLS 5.1 and I'm getting the
"dreaded" ClassCastException every time when JSP tries to read a bean
from the request or session. Under my architecture (actually it's just
the regular "model 2" ) bean is populated by a servlet, set on the
request and then retrieved by JSP (servlet forwards to JSP). Everything
work fine when I register servlets in weblogic.properties, but
ClassCastException is thrown on any attempt to read from the request if
the same JSPs and servlets are deployed as web application.
Has anybody come across the same problem?
Thanks in advance for help.
Alexander
Hello,
This is all well and good as a temporary bug, but it's totally unrealistic for
the future. Two points:
* The ClassLoader doesn't need to be discarded, it just needs to be cleared.
* Other servlet engines seem to be able to handle this.
Hope it's on its way to resolution!

Hi
I did connection with AS400 database.When I am trying run JDE.jsf file then I am getting java.lang.ClassCastException: weblogic.jdbc.wrapper.PoolConnection_com_ibm_as400_access_AS400JDBCConnection cannot be cast to oracle.jdbc.OracleConnection error.
I have added jt400.jar file C:\Users\k\AppData\Roaming\JDeveloper\system11.1.2.4.39.64.36.1\DefaultDomain\lib
and C:\Oracle\Middleware11gJdev\wlserver_10.3\server\lib.
Please let me know, how to handle this exception and get proper output.

OC4J 9.0.3 ClassCastException instability
Hi,
I´m trying to use OC4J 9.0.3 StandAlone, I packaged the app on a EAR and deploied them using JDeveloper 9.0.3.
The deploy was fine and the app runs nicely for about 3 or 5 hours but then the OC4J throws ClassCastException when I try to access one JSP file that has a CustomTag and throws a ClassCastException when try to run the getTagHandle method on the servlet.
This problem is realy a uncommon error and it is generate completly random !
I tried to deploy the same app on 9iAS (9.0.2) and I got another strange error:

Thanks,
FelipeAre you calling an EJB from the customTag class.
If so make sure that you declare the ejb app as the parent in he server.xml file
here is a sammple of my server.xml file
<application name="ejb1" path="../applications/_ejb1.ear" auto-start="true" />
<application name="struts-ex" path="../applications/webapp1.ear" parent="ejb1" auto-start="true" /> -
EJB lookup returned stub from a different classloader.
I've written an EJB for doing authenitcation. This EJB is accessed by an security-mbean (BEA's login module).
- The EJB is deployed in an EAR.
- The EJB-stubs are extracted and is included as part of the MBEAN Jar.
When I hit a webapp causing the EJB lookup to occur, the stub object returned is created by the webapp's classloader. This cause a ClassCastException when trying to cast the returned home interface into the home interface of the MBEAN's classloader.
Note that all this is happening on the same BEA server running WLS8.1.
I don't want to put the EJB jar on the system classpath so I can redeploy the EJB, the Application's EAR and the MBEAN to a cluster.

Thanks for responding to my question, which newsgroup is more appropriate for
my line of question?
But before I move this thread, I would like to add:
I've already handled the recursion problem on top of the ejb-lookup before JNDI
becomes avaliable (while doing server startup) problem.
The advantage with the EJB model is this. By changing the host/port configuration,
I can switch between a local-authentication server or a remote provide authentication
server network configuration.
If I were to include the necessary classes in the mbean JAR from our application,
there maybe resources issues since I now have 2 classloaders loading my server-portion
of classes. Not sure how that will workout with resources and all. This model
has the disadvantage of any classes I have in the mbean JAR will require updates
outside my EAR. This wroks against the EAR deployment model.

This isn't a good approach. You are pretty much stuffed mainly for the
reasons you outline.
Also note that if you continue to go down this road you will have to
handle the potential recursion (i.e accessing an EJB will invoke a
security call to your provider!).
Why do you need to implement this as an EJB? The main advantages of EJBs
are security and container managed transactions neither of which is
relevant here surely?

Classloading [EAR] - [webapp.war+ejb.jar]
Hi.
I've got a problem with the classloader hierarchy in WL 6.0.
When I deploy my war/ejb application as an EAR, everything works fine.
But I want (for several reasons) to deploy
EJB jars and WebApp wars (or exploded Web Apps) seperately.
WL 6.0 EJB classloader doesn't export remote/home interfaces and
helper classes,
so my web app can't find them.
When I include that interfaces/classes in my Web App, I get
occasionally ClassCastExceptions (I assume depending on classloader
caching).
Is there a way to configure the classloader hierarchy, or do you have
any other solution for this?
Thanks,
RomanHello,
I have a big application to do.
So, one solution should be to use an EAR for one
module, containing the WAR for the web-tier and the
EJB-JAR for the business-tier.
It would be better doing like this than creating a
big WAR, in order to avoid to deploy a big WAR when a
modification is done in one module.Are you using local EJBs or remote EJBs? The only way for a war to talk to a local EJB is to package the war along with the ejb-jar in an EAR file because they need to be collocated. You can not simply bundle EJB classes in a war file.
If you are using remte EJBs, then you can package the EJB client view classes along with the servlets and JSPs in the war file and deploy the war separately. But again your war will be one big war.
If your EJBs are just entity beans, then Java EE 5 (see http://weblogs.java.net/blog/ss141213/archive/2005/12/using_java_pers.html) allows you some nice options.

What about the problem of the session ?
In fact, I have to declare a context-root for one
EAR.
And at each context-root is created an object
HttpSession on the server.
So, I have some questions about this :
- How can I configure my WARs in order to use only
one HttpSession object for every WARs ?
There is no standard way to do this. Relying on any application server specific feature can only make your app non-portable. So I strongly recommend you not to do this.
- Can I put multiple WARs in one EAR ?Of course you can.
If yes, what about the context-root ? This solution would resolve
the session problem.Can't be solved using any standard way. So I suggest you stick to one big war, if that's what your business requirement is.To speed up development-deployment-test cycle, any appserver allows a rapid deployment option where in you can deploy incremental changes to server. Use this facility during development. DON'T sacrifice portability of your app by using any product specific configuration that you may not find any where else.
Thanks,

Classloader issue when deploying a war file
Hello,
Using Jdev 11.1.1.3 with WebLogic 10.3.2.0 when we deploy a new version of our war file we get a ClassCastException for an entity class that cannot be cast on itself ! We are using standalone JPA for persistence.
Caused by: javax.faces.el.EvaluationException: java.lang.ClassCastException: gouv.micc.intimm.pers.model.entite.Personne cannot be cast to gouv.micc.intimm.pers.model.entite.Personne
It looks like a classloader cache issue. This happend even if we first delete the war file before we upload a new one. The only way to solve this is to restart WebLogic. Any idea?Seems like a WebLogic issue - try asking on that forum:

Servlet passing values to JSP and ClasscastException
I am using weblogic 5.1 to run my Servlets.
I want to know when I forward from a servlet to a JSP how do I pass

classes).
Uptil now I have been putting all values in the session from where the
JSP picks them up, but somehow I have a feeling that this is not the
right way.
In a code I am putting a Java Object (It contains two attributes of
Java.util.Vector type) in the session so that the JSP to which I am
forwarding it to can use it I have put my class in the ServletClasses.
Intertestingly it runs well till the contents of the Vector are changed.
As the contents of the vector are changed, it throws ClassCastException

Only can confirm your finding - the jsp is using a different class loader to the servlet that originally instantiated the object. There's the rub. I haven't figured out yet how to fix that. I can get the classloader but don't know how to get the runtime to use that class loader to perform cast.

ClassCastException when I access an EJB from a remote EJB in WL 8.1
I am using WebLogic 8.1 and am trying to lookup the home interface for an EJB (_ejbRemote_)
from another EJB (_ejbCurrent_). They are deployed in seperate EARs. When I bundle
the home and remote interfaces for ejbRemote in the EAR file that ejbCurrent
is deployed in, everything works fine. But I need to be able to configure ejbRemote
at run time and my customers don't want to have to bundle their classes in my
EAR. So I invoke a custom classloader (of type java.net.URLClassLoader) that will
load the home and remote interface classes for ejbRemote from a configurable
location at runtime. This finds the classes no problem, and the InitialContext.lookup()
returns a stub, but I get a 'java.lang.ClassCastException: Cannot narrow remote
object' error when I call PortableRemoteObject.narrow(home, homeClass);
The code looks like:
// Assume EJBHomeStr = "com.foo.TestHome" in this case
// Load the home interface class. This works.
Class homeClass = urlClassLoader.loadClass(EJBHomeStr);
// Lookup the home interface. This works.
Object lookedUpHomeObject = initialContext.lookup(JNDIName);
// This fails.
Object homeObject = PortableRemoteObject.narrow(lookedUpHomeObject, homeClass);
And the weblogic error looks like
... ; nested exception is:
java.lang.ClassCastException: Cannot narrow remote object to com.foo.TestHome
at weblogic.iiop.PortableRemoteObjectDelegateImpl.narrow(PortableRemoteO
bjectDelegateImpl.java:219)
at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:134)
at ...[the rest is just my application code stack...]
When I log the ClassLoaders for the affected objects, using getClass().getClassLoader(),
I get:
<snippet from log follows>
getClass().getClassLoader(): weblogic.utils.classloaders.GenericClassLoader@667da1
finder:
weblogic.utils.classloaders.MultiClassFinder@db9199 annotation: myEJBApp@
homeClass.getName(): com.foo.TestHome classloader = java.net.URLClassLoader@4f1707
lookedUpHomeObject.getClass().getName(): com.foo.Test_EJB_kx82zy_HomeImpl_810_WLStub
classloader = weblogic.utils.classloaders.GenericClassLoader@667da1
finder: weblogic.utils.classloaders.MultiClassFinder@db9199 annotation: myEJBApp@
<end snippet from log>
So it appears that since the looked up Stub was loaded by the WebLogic classloader
and the actual Home class was loaded by my URLClassLoader, the narrow() can't
reconcile the two. I have tried both rmic and the Weblogic appc command to pre-generate
the stubs, which I put in the same JAR as my home and remote interface classes
and load with my custom classloader. But the standard stub (generated by either
rmic or appc) is named TestHomeStub.class and Weblogic is ignoring those and
making a class with the name Test_EJB_kx82zy_HomeImpl_810_WLStub, as shown above.
I have also tried to put the remote interface classes and stubs in the System
classpath using the -classpath option when I start WebLogic, but same result.
The question is, Is there a way in WebLogic to communicate with a remote EJB in
a seperate EAR without bundling anything about that remote EAR in my EAR? Or is
there something I've missed? I need to keep my application J2EE compliant, meaning
I can't hardcode any AppServer-specific code in my application.
Thanks.Hi Jon,
Glad to hear that.

I fixed the problem. It turns out I didn't need to use a custom classloader at
all, I just use Reflection directly on the classes ruturned from my JNDI lookup.
So when I lookup the home class, I don't need to narrow or cast it, I just use
Reflection to invoke the "create" method. Then I use the object that I get from
create and directly invoke whatever method on it I need, again using Reflection.
And that works.

Hi Jon,
The problem is, this class is not available for the classloader
running your "main code".
You can try to hack the into the thread context class loader:
Thread thread = Thread.currentThread();
ContextClassLoader originalClassLoader = thread.getContextClassLoader();
try {
YourURLClassloader yourClassLoader = new
YourURLClassloader(originalClassLoader);
thread.setContextClassLoader(yourClassLoader );
// your code goes here
} finally {
// Don't forget to restore it !!!
thread.setContextClassLoader(originalClassLoader);
Be very cautious. If you fail to restore the original context class loader,
you will likely have to restart the server.
Hope this helps.

// Lookup the home interface. This works.
Object lookedUpHomeObject = initialContext.lookup(JNDIName);
// This fails.
Object homeObject = PortableRemoteObject.narrow(lookedUpHomeObject,homeClass);
And the weblogic error looks like
... ; nested exception is:
java.lang.ClassCastException: Cannot narrow remote object tocom.foo.TestHome
at weblogic.iiop.PortableRemoteObjectDelegateImpl.narrow(PortableRemoteO
bjectDelegateImpl.java:219)
at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:134)
at ...[the rest is just my application code stack...]
When I log the ClassLoaders for the affected objects, using getClass().getClassLoader(),
I get:
<snippet from log follows>
getClass().getClassLoader(): weblogic.utils.classloaders.GenericClassLoader@667da1
finder:
weblogic.utils.classloaders.MultiClassFinder@db9199 annotation: myEJBApp@
homeClass.getName(): com.foo.TestHome classloader = java.net.URLClassLoader@4f1707
lookedUpHomeObject.getClass().getName(): com.foo.Test_EJB_kx82zy_HomeImpl_810_WLStub
classloader = weblogic.utils.classloaders.GenericClassLoader@667da1
finder: weblogic.utils.classloaders.MultiClassFinder@db9199 annotation:myEJBApp@
<end snippet from log>
So it appears that since the looked up Stub was loaded by the WebLogicclassloader
and the actual Home class was loaded by my URLClassLoader, the narrow()can't
reconcile the two. I have tried both rmic and the Weblogic appc commandto pre-generate
the stubs, which I put in the same JAR as my home and remote interfaceclasses
and load with my custom classloader. But the standard stub (generatedby either
rmic or appc) is named TestHomeStub.class and Weblogic is ignoringthose and
making a class with the name Test_EJB_kx82zy_HomeImpl_810_WLStub, asshown above.
I have also tried to put the remote interface classes and stubs inthe System
classpath using the -classpath option when I start WebLogic, but sameresult.
The question is, Is there a way in WebLogic to communicate with a remoteEJB in
a seperate EAR without bundling anything about that remote EAR in myEAR? Or is
there something I've missed? I need to keep my application J2EE compliant,meaning
I can't hardcode any AppServer-specific code in my application.

Casting to an abstract class from a different classloader
I have a class Special that extends an abstract class Base. In my code I use a URLClassLoader to load the class Special and I then want to cast Special to Base. If I do this I get a ClassCastException because the classes are loaded from different classloaders. I can't have the URLClassLoader and the class that performs the cast extend a parent ClassLoader that knows about the Base class. What I want to be able to do is something like this:
URLClassLoader loader = new URLClassLoader(codebase, null);
Class baseClass = loader.loadClass(className);
Base baseObj = (Base)baseClass.newInstance();
I have seen some post that suggest I can achieve this using Reflection but I am not sure how to go about this. Any help would be appreciated.
Thanks
Jim.Thanks for your help so far but I still can't do the casting, consider this example:
//Base.java
package classTest;
public interface Base
public abstract void execute();
//ConcBase.java
package classTest;
public class ConcBase implements Base
public void execute()
System.out.println("execute in ConcBase called");
I compile these files and jar them into work.jar
I now have my application:
//Test.java
import java.net.*;
import java.io.*;
import classTest.*;
public class Test
public static void main(String[] args)
Test t = new Test();
t.test();
public void test()
try
File file = new File("D:/Projects/classloadTest/work.jar");
URL[] codebase = {file.toURL()};
ClassLoader ccl = getClass().getClassLoader();
ccl.loadClass("classTest.Base");
URLClassLoader ucl = new URLClassLoader(codebase,ccl);
Class conClass = ucl.loadClass("classTest.ConcBase");
classTest.Base b = (classTest.Base)conClass.newInstance();
b.execute();
catch(Exception t)
System.out.println("thowable caught");
t.printStackTrace(System.out);
I compile this and run it with this command:
java -classpath D:\Projects\classloadTest\work.jar;. Test
This runs as I would expect, however I have set the parent class loader of my custom URLClassLoader to the one that does the cast, this means that Base and ConcBase are both being picked up by the application class loader as my custom class loader delegates to its parent. This is the current behaviour I have in my proper application and it is causing problems, I don't want the class that implements Base to delegate to any class on the main applications classpath. If I change the line:
URLClassLoader ucl = new URLClassLoader(codebase,ccl);
In Test.java to:
URLClassLoader ucl = new URLClassLoader(codebase,null);
I get a ClassCastException, this is because the class that does the cast (Test) loads Base from it's classpath and ConcBase is loaded from the URLClassLoader. After spending more time looking at this problem I don't think there is anyway to resolve but if anyone thinks there is please tell me.
Many thanks
Jim.
