Base 64 decoding in web service

[Gabsaga Tata]

I am using the package org.apache.soap.encoding.soapenc.Base64 to decode base 64 encoded data. Below is my decode method in my webservice app.     public byte[] base64DecodeData(String data)     {             byte[] bytes = null;               Base64 base64 = new Base64();         try         {             bytes = base64.decode(data);                }         catch (Exception ex)         {             System.out.println("Decoding exception: " + ex.toString());         }         return bytes;           } The string data parameter is the value extracted from element tag: <data encoding="base64-MIME">Base64EncodedDataHere</data> from a DOM Object where the value bas been base 64 encoded by the client application.     I get the following error when running my base64DecodeData method. Any ideas what could be causing this? When my webservice is implemented as a regular java class, it works fine but when I convert it to a webservice, I get this error. Any help will be greatly appreciated.     AxisFault  faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException  faultSubcode:  faultString: java.lang.reflect.InvocationTargetException  faultActor:  faultNode:  faultDetail:         {http://xml.apache.org/axis/}hostname:USAGXXTEST2286 java.lang.reflect.InvocationTargetException         at org.apache.axis.message.SOAPFaultBuilder.createFault(SOAPFaultBuilder.java:221)         at org.apache.axis.message.SOAPFaultBuilder.endElement(SOAPFaultBuilder.java:128)         at org.apache.axis.encoding.DeserializationContext.endElement(DeserializationContext.java:1087)         at org.apache.xerces.parsers.AbstractSAXParser.endElement(Unknown Source)         at org.apache.xerces.impl.XMLNSDocumentScannerImpl.scanEndElement(Unknown Source)         at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(Unknown Source)         at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source)         at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source)         at org.apache.xerces.parsers.DTDConfiguration.parse(Unknown Source)         at org.apache.xerces.parsers.XMLParser.parse(Unknown Source)         at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source)         at javax.xml.parsers.SAXParser.parse(Unknown Source)         at org.apache.axis.encoding.DeserializationContext.parse(DeserializationContext.java:227)         at org.apache.axis.SOAPPart.getAsSOAPEnvelope(SOAPPart.java:696)         at org.apache.axis.Message.getSOAPEnvelope(Message.java:424)         at org.apache.axis.handlers.soap.MustUnderstandChecker.invoke(MustUnderstandChecker.java:62)         at org.apache.axis.client.AxisClient.invoke(AxisClient.java:206)         at org.apache.axis.client.Call.invokeEngine(Call.java:2765)         at org.apache.axis.client.Call.invoke(Call.java:2748)         at org.apache.axis.client.Call.invoke(Call.java:2424)         at org.apache.axis.client.Call.invoke(Call.java:2347)         at org.apache.axis.client.Call.invoke(Call.java:1804)         at com.simpaq.ws.CipherSoapBindingStub.processDocument(CipherSoapBindingStub.java:153)         at CipherClient.run(CipherClient.java:78)         at CipherClient.main(CipherClient.java:105)
