Hi,
			

			Sorry for being little over descriptive here. I have an issue deserializing a file that contains a Map
			>. These POJO bean classes are stored in a
			

			jar file uder web-app/lib. I can deserialize the file from a standalone java program, from tomcat web app when tomcat is started from within Eclipse IDE; but
			

			I can not get it to work from the same webapp when tomcat is started in standalone mode (not from within IDE). I have some javabeans added into a List object, which
			

			is added to a LinkedHashMap object in the serialized file.
			

			

			This is the partial stack trace -
			

			java.lang.ClassNotFoundException: com.biz.icomp.dbi.DBCustomer
			

			at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
			

			at java.security.AccessController.doPrivileged(Native Method)
			

			at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
			

			at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
			

			at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:268)
			

			at java.lang.ClassLoader.loadClass(ClassLoader.java:251)
			

			at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319)
			

			at java.lang.Class.forName0(Native Method)
			

			at java.lang.Class.forName(Class.java:242)
			

			at java.io.ObjectInputStream.resolveClass(ObjectInputStream.java:585)
			

			

			This is the code -
			

			FileInputStream fis = new FileInputStream(serializedFilePath);
			

			ObjectInputStream ois = new ObjectInputStream(fis);
			

			Map map = (Map)ois.readObject();
			

			ois.close();
			

			

			I even tried to override the default class loader as -
			

			ClassLoader old = Thread.currentThread().getContextClassLoader();
			

			FileInputStream fis = new FileInputStream(serializedFilePath);
			

			ObjectInputStream ois = new ObjectInputStream(fis);
			

			File root = new File(
			);
			

			URLClassLoader urlLoader = new URLClassLoader(new URL[] { root.toURL() }, Thread.currentThread().getContextClassLoader());
			

			Map map = (Map)ois.readObject();
			

			ois.close();
			

			Thread.currentThread().setContextClassLoader(old);
			

			

			It still doesn't work. I also tried printing the default class loader and the loader after overriding it. This is what I see -
			

			>
			When run from a standalone java class-
			

			Default Class Loader ->
			sun.misc.Launcher$AppClassLoader@a39137
			

			URLClassLoader Class Loader ->
			java.net.URLClassLoader@127f79d
			

			

			>
			When run from tomcat started directly (not from IDE)-
			

			Default Class Loader ->
			
				WebappClassLoader
				

				delegate: false
				

				repositories:
				

				/WEB-INF/classes/
				

				----------> Parent Classloader:
				

				org.apache.catalina.loader.StandardClassLoader@25c828
			
			(
			these last 3 lines are automatically printed
			)
			

			

			URLClassLoader Class Loader ->
			java.net.URLClassLoader@170a4d0
			

			

			>
			When run from tomcat started within Eclipse-
			

			Default Class Loader ->
			
				WebappClassLoader
				

				delegate: false
				

				repositories:
				

				/WEB-INF/classes/
				

				----------> Parent Classloader:
				

				org.apache.catalina.loader.StandardClassLoader@10d4f27
			
			

			

			URLClassLoader Class Loader ->
			java.net.URLClassLoader@1ec4333
			

			

			So, the class loaders are same whether or not the tomcat is started from within IDE. The class which is not found by the class loader, is actually there in a
			

			jar file in WEB-INlib. As I said, it works when I start tomcat from eclipse. Am I missing anything? If this is a classpath issue,
			

			I am not sure how should I resolve it. Appreciate your help.
