Serialization issue
I'm trying to grab the current session ID and the request parameter map from the current request and serialize them into a base64 string to pass to a PHP application. Problem is, I keep running into the following exception everytime I try to serialize anything imlementing the Map interface: java.io.NotSerializableException: org.apache.coyote.tomcat5.CoyoteWriter at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1054) at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:13 32) at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1304) at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1 247) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1052) at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:13 32) at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1304) at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1 247) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1052) at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:278) at com.enertiasoft.util.Base64.encodeObject(Base64.java:348) at com.enertiasoft.session.SessionServlet$SessionProxy.toString(SessionServ let.java:125) at com.enertiasoft.session.SessionServlet.service(SessionServlet.java:50) at javax.servlet.http.HttpServlet.service(HttpServlet.java:856) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(Applica tionFilterChain.java:284) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilt erChain.java:204) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValv e.java:256) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveCo ntext.java:151) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:5 63) at org.apache.catalina.core.StandardContextValve.invokeInternal(StandardCon textValve.java:245) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValv e.java:199) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveCo ntext.java:151) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:5 63) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java :195) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveCo ntext.java:151) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java :164) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveCo ntext.java:149) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:5 63) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve. java:156) at org.apache.catalina.core.StandardValveContext.invokeNext(StandardValveCo ntext.java:151) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:5 63) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:972) at org.apache.coyote.tomcat5.CoyoteAdapter.service(CoyoteAdapter.java:209) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:78 1) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.processC onnection(Http11Protocol.java:549) at org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:58 9) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool .java:666) at java.lang.Thread.run(Thread.java:534) What is the CoyoteWriter object I keep running inot, and how can I mark it as transient?

Re: Serialization issue
Right now I get the exception even when I try to serialize a HashMap I just created, without any data in it. I would guess that any request parameters stored in the map returned by request.getParameterMap() should be serializable right? I don't understand how, f I'm serializing a new serializable object, the CyoteWriter get's involved.

It's the HTTP connector's writer, and you can't mark it as transient. You would have to manually remove non-serializable attributes from a copy of the Map before you try to serialize the copy.

JMX questions
Background: I'm trying to implement a custom MBean to be accessable through the /manager/jmxproxy application. I've read the mbeans-descriptor-howto document, and have put together what I believe is a correct descriptor, and don't get any errors when tomcat (version 5 is what we're using) starts up. Problem is, I don't see my MBean through the proxy interface. Question: Does jmxproxy support custom MBeans? If so, does it support only Model MBeans? I ask this because my MBean is a simple one, not dynamic or model. Is there any way to test that my MBean is loaded and accessable, short of putting together a seperate JMX agent or client to access it? If I wanted to use an external client to manage all of tomcat's MBeans, inclusing my custom one, how would i go about that? Thanks in advance for any help.
