Hi Scott, I've got following trouble I am using Apache SOAP as RPC now I tried to give my serverroutine Maps in Vectors I am getting a Nullpointexception, because I am using HashMaps which allow null-values in the Map serializier a HashTable is used which does not allow null-values. What is the reason a HashTable is performing for Maps an not a HashMap? If a Map is used, which does not allow null-values the client will allready know that while filling it with entries. So I believe it does not need to be so restrictive. Since passing a Map is really a standard I don't prefer writing a new serializer/deserializer on my own.
My Exception is the following: java.lang.NullPointerException at java.util.Hashtable.put(Hashtable.java:393) at java.util.Hashtable.putAll(Hashtable.java:467) at org.apache.soap.encoding.soapenc.MapSerializer.marshall(Unknown Source) at org.apache.soap.util.xml.XMLJavaMappingRegistry.marshall(Unknown Source) at org.apache.soap.encoding.soapenc.VectorSerializer.marshall(Unknown Source) at org.apache.soap.encoding.soapenc.ParameterSerializer.marshall(Unknown Source) at org.apache.soap.rpc.RPCMessage.serializeParams(Unknown Source) at org.apache.soap.rpc.RPCMessage.marshall(Unknown Source) at org.apache.soap.Body.marshall(Unknown Source) at org.apache.soap.Envelope.marshall(Unknown Source) at org.apache.soap.transport.http.SOAPHTTPConnection.send(Unknown Source) at org.apache.soap.rpc.Call.invoke(Unknown Source) at org.apache.soap.rpc.Call.invoke(Unknown Source) at de.mc.etnbestterm.data.SoapCallingDataHolder.callSoaply(SoapCallingDataHolde r.java:93) at de.mc.etnbestterm.data.OrderDataHolder.orderArtikelsInBasket(OrderDataHolder .java:2047) at de.mc.etnbestterm.gui.WKBestellungsPanel.sendAnforderung(WKBestellungsPanel. java:324) at de.mc.etnbestterm.gui.WKBestellungsPanel.m_artikelSpecialButton_actionPerfor med(WKBestellungsPanel.java:225) at de.mc.etnbestterm.gui.BasketPanel$4.actionPerformed(BasketPanel.java:104) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:1786) at javax.swing.AbstractButton$ForwardActionEvents.actionPerformed(AbstractButto n.java:1839) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:4 20) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:258) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(BasicButtonListener .java:245) at java.awt.Component.processMouseEvent(Component.java:5100) at java.awt.Component.processEvent(Component.java:4897) at java.awt.Container.processEvent(Container.java:1569) at java.awt.Component.dispatchEventImpl(Component.java:3615) at java.awt.Container.dispatchEventImpl(Container.java:1627) at java.awt.Component.dispatchEvent(Component.java:3477) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:3483) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:3198) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:3128) at java.awt.Container.dispatchEventImpl(Container.java:1613) at java.awt.Window.dispatchEventImpl(Window.java:1606) at java.awt.Component.dispatchEvent(Component.java:3477) at java.awt.EventQueue.dispatchEvent(EventQueue.java:456) at java.awt.EventDispatchThread.pumpOneEventForHierarchy(EventDispatchThread.ja va:201) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java :151) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:145) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:137) at java.awt.EventDispatchThread.run(EventDispatchThread.java:100) ____________ Virus checked by G DATA AntiVirusKit Version: AVK 15.0.448 from 13.10.2004 Virus news: www.antiviruslab.com
