Local transactions support -------------------------- Key: JCR-1446 URL: https://issues.apache.org/jira/browse/JCR-1446 Project: Jackrabbit Issue Type: Improvement Components: jackrabbit-jca Affects Versions: 1.5 Reporter: Stephane Landelle
JCAManagedConnectionFactory doesn't currently support LocalTransaction. Wouldn't it be simple to provide a simple implemetation like the following (inspired of JR test suite): package com.weka.jackrabbit.jca; import javax.jcr.Session; import javax.resource.ResourceException; import javax.resource.spi.LocalTransaction; import javax.transaction.xa.XAException; import javax.transaction.xa.XAResource; import javax.transaction.xa.Xid; import org.apache.jackrabbit.api.XASession; /** * JackRabbit Local transaction (based on the XA Resource returned by * JackRabbit). <p/> Inspired from JackRabbit test suite. * * Internal [EMAIL PROTECTED] javax.transaction.LocalTransaction} implementation. * */ public class JackRabbitLocalTransaction implements LocalTransaction { /** * Global transaction id counter. TODO: remove the static attribute */ private static byte counter = 0; /** * XASession */ private XASession session; /** * XAResource */ private final XAResource xares; /** * Xid */ private Xid xid; /** * Create a new instance of this class. Takes a session as parameter. * * @param session * session. If session is not of type [EMAIL PROTECTED] XASession}, an * <code>IllegalArgumentException</code> is thrown */ public JackRabbitLocalTransaction(Session session) { if (session instanceof XASession) { this.session = (XASession) session; xares = this.session.getXAResource(); } else { throw new IllegalArgumentException("Session not of type XASession"); } } /** * @see javax.transaction.LocalTransaction#begin */ public void begin() throws ResourceException { try { xid = new XidImpl(counter++); xares.start(xid, XAResource.TMNOFLAGS); } catch (XAException e) { throw new ResourceException("Unable to begin transaction: " + "XA_ERR=" + e.errorCode); } } /** * @see javax.transaction.LocalTransaction#commit */ public void commit() throws ResourceException { try { xares.end(xid, XAResource.TMSUCCESS); xares.prepare(xid); xares.commit(xid, false); session.logout(); } catch (XAException e) { if (e.errorCode >= XAException.XA_RBBASE && e.errorCode <= XAException.XA_RBEND) { throw new ResourceException(e.toString()); } throw new ResourceException("Unable to commit transaction: " + "XA_ERR=" + e.errorCode); } } /** * @see javax.transaction.LocalTransaction#rollback */ public void rollback() throws ResourceException { try { xares.end(xid, XAResource.TMFAIL); xares.rollback(xid); session.logout(); } catch (XAException e) { throw new ResourceException("Unable to rollback transaction: " + "XA_ERR=" + e.errorCode); } } /** * Internal [EMAIL PROTECTED] Xid} implementation. */ class XidImpl implements Xid { /** Global transaction id */ private final byte[] globalTxId; /** * Create a new instance of this class. Takes a global transaction * number as parameter * * @param globalTxNumber * global transaction number */ public XidImpl(byte globalTxNumber) { this.globalTxId = new byte[] { globalTxNumber }; } /** * @see javax.transaction.xa.Xid#getFormatId() */ public int getFormatId() { return 0; } /** * @see javax.transaction.xa.Xid#getBranchQualifier() */ public byte[] getBranchQualifier() { return new byte[0]; } /** * @see javax.transaction.xa.Xid#getGlobalTransactionId() */ public byte[] getGlobalTransactionId() { return globalTxId; } } /** * @return Returns the counter. */ public byte getCounter() { return counter; } /** * @param counter * The counter to set. */ public void setCounter(byte counter) { JackRabbitLocalTransaction.counter = counter; } } -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
