Is there any possible solution for it? ( We are using JAVA 5 VM 64.   It is difficult to upgrade jboss because there is other service on it .   But it is possible to upgrade jboss web service if it could prevent OOM ) I also want to know how can I get a source of jboss web service executed on jboss4.0.2.   Below is stack trace of OOM.   02/22/2010 10:37:58,889 ERROR [[OaxApiBean]] Servlet.service() for servlet OaxApiBean threw exception java.lang.OutOfMemoryError: Java heap space     at org.jboss.axis.message.SAX2EventRecorder$objArrayVector.add(SAX2EventRecorder.java:366)     at org.jboss.axis.message.SAX2EventRecorder.startEntity(SAX2EventRecorder.java:180)     at org.jboss.axis.encoding.DeserializationContextImpl.startEntity(DeserializationContextImpl.java:1349)     at org.apache.xerces.parsers.AbstractSAXParser.startParameterEntity(Unknown Source)     at org.apache.xerces.parsers.AbstractSAXParser.startGeneralEntity(Unknown Source)     at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.handleCharacter(Unknown Source)     at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanEntityReference(Unknown Source)     at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$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.XML11Configuration.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.jboss.axis.encoding.DeserializationContextImpl.parse(DeserializationContextImpl.java:257)     at org.jboss.axis.MessagePart.getAsSOAPEnvelope(MessagePart.java:684)     at org.jboss.axis.Message.getSOAPEnvelope(Message.java:428)     at org.jboss.axis.Message.getContentType(Message.java:494)     at org.jboss.axis.transport.http.AxisServlet.doPost(AxisServlet.java:971)     at javax.servlet.http.HttpServlet.service(HttpServlet.java:717)     at org.jboss.axis.transport.http.AxisServletBase.service(AxisServletBase.java:370)     at javax.servlet.http.HttpServlet.service(HttpServlet.java:810)     at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252)     at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173)     at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81)     at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202)     at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173)     at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213)     at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178)     at org.jboss.web.tomcat.security.CustomPrincipalValve.invoke(CustomPrincipalValve.java:39)     at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:153)     at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:482) -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/527645#527645
