[jira] [Commented] (QPID-3307) ClassNotfound Exception when using Qpid java client in Complex classloading Environments.

Actually i found a way to simulate the Environment but i caught up with some work and couldn't find a time to work on a unit test case. I think happy path is already covered in the current serialization test cases we have. Only thing is i need to add a test case that simulates the above mentioned class loading environment. Will be able to provide a patch for that soon, possibly in next weekend. thanks, Charith ClassNotfound Exception when using Qpid java client in Complex classloading Environments. --- Key: QPID-3307 URL: https://issues.apache.org/jira/browse/QPID-3307 Project: Qpid Issue Type: Bug Components: Java Client Reporter: Charith Dhanushka Wickramarachchi Assignee: Robbie Gemmell Priority: Critical Attachments: QPID-3307_patch.txt, QPID-3307_patch.txt, QPID-3307_patch.txt, QPID-3307_patch_unit_test.txt Hi , When we are using qpid client to receive JMSObject in complex class loading environments like web application containers/Osgi environments .There is a scenario where this issues comes. Scenario. In a web application container normally they use a class loader per web app. and if we have qpid client libs at the root classloader level this error can come. The reason for this is Serializable Object types that are used inside the web app are not visible to the class loader that loads the JMSObject message and unmarshall it. thanks, Charith -- This message is automatically generated by JIRA.

Yes you are correct i was looking at Test cases in systests/src/main/java. As you mentioned the scenario covered by the test case i have provided is already covered in org.apache.qpid.test.unit.client.message.ObjectMessageTest. I see there is no unit test for Object messages in package org.apache.qpid.test.unit.client.message to I'll add an unit test for it and provide a patch. thanks, Charith ClassNotfound Exception when using Qpid java client in Complex classloading Environments. --- Key: QPID-3307 URL: https://issues.apache.org/jira/browse/QPID-3307 Project: Qpid Issue Type: Bug Components: Java Client Reporter: Charith Dhanushka Wickramarachchi Priority: Critical Attachments: QPID-3307_patch.txt, QPID-3307_patch.txt, QPID-3307_patch.txt, QPID-3307_patch_unit_test.txt Hi , When we are using qpid client to receive JMSObject in complex class loading environments like web application containers/Osgi environments .There is a scenario where this issues comes.

[jira] [Updated] (QPID-3307) ClassNotfound Exception when using Qpid java client in Complex classloading Environments.
[ https://issues.apache.org/jira/browse/QPID-3307?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Charith Dhanushka Wickramarachchi updated QPID-3307: Attachment: QPID-3307_patch_unit_test.txt Hi , I'm attaching an unit test case which will send receive an Object Message which have a custom Serializable Type inside.In that case the ObjectInputStream i have provided will be used. To re-create the exact class loading scenario I'll have to find a way to simulate that kind of class loading environment within the Unit test. I'll have to think through it on how to implement that. thanks, Charith ClassNotfound Exception when using Qpid java client in Complex classloading Environments. --- Key: QPID-3307 URL: https://issues.apache.org/jira/browse/QPID-3307 Project: Qpid Issue Type: Bug Components: Java Client Reporter: Charith Dhanushka Wickramarachchi Priority: Critical Attachments: QPID-3307_patch.txt, QPID-3307_patch.txt, QPID-3307_patch.txt, QPID-3307_patch_unit_test.txt Hi , When we are using qpid client to receive JMSObject in complex class loading environments like web application containers/Osgi environments .There is a scenario where this issues comes.
