示例1: performCodeSetNegotiation
import com.sun.corba.se.spi.transport.CorbaConnection; //导入方法依赖的package包/类
protected void performCodeSetNegotiation(CorbaMessageMediator messageMediator)
{
CorbaConnection conn =
(CorbaConnection) messageMediator.getConnection();
IOR ior =
((CorbaContactInfo)messageMediator.getContactInfo())
.getEffectiveTargetIOR();
GIOPVersion giopVersion = messageMediator.getGIOPVersion();
// XXX This seems to be a broken double checked locking idiom: FIX IT!
// conn.getCodeSetContext() is null when no other requests have
// been made on this connection to trigger code set negotation.
if (conn != null &&
conn.getCodeSetContext() == null &&
!giopVersion.equals(GIOPVersion.V1_0)) {
synchronized(conn) {
// Double checking. Don't let any other
// threads use this connection until the
// code sets are straight.
if (conn.getCodeSetContext() != null)
return;
// This only looks at the first code set component. If
// there can be multiple locations with multiple code sets,
// this requires more work.
IIOPProfileTemplate temp =
(IIOPProfileTemplate)ior.getProfile().
getTaggedProfileTemplate();
Iterator iter = temp.iteratorById(TAG_CODE_SETS.value);
if (!iter.hasNext()) {
// Didn't have a code set component. The default will
// be to use ISO8859-1 for char data and throw an
// exception if wchar data is used.
return;
}
// Get the native and conversion code sets the
// server specified in its IOR
CodeSetComponentInfo serverCodeSets
= ((CodeSetsComponent)iter.next()).getCodeSetComponentInfo();
// Perform the negotiation between this ORB's code sets and
// the ones from the IOR
CodeSetComponentInfo.CodeSetContext result
= CodeSetConversion.impl().negotiate(
conn.getBroker().getORBData().getCodeSetComponentInfo(),
serverCodeSets);
conn.setCodeSetContext(result);
}
}
}
示例2: addCodeSetServiceContext
import com.sun.corba.se.spi.transport.CorbaConnection; //导入方法依赖的package包/类
protected void addCodeSetServiceContext(CorbaConnection conn,
ServiceContexts ctxs,
GIOPVersion giopVersion) {
// REVISIT. OMG issue 3318 concerning sending the code set
// service context more than once was deemed too much for the
// RTF. Here's our strategy for the moment:
//
// Send it on every request (necessary in cases of fragmentation
// with multithreaded clients or when the first thing on a
// connection is a LocateRequest). Provide an ORB property
// to disable multiple sends.
//
// Note that the connection is null in the local case and no
// service context is included. We use the ORB provided
// encapsulation streams.
//
// Also, there will be no negotiation or service context
// in GIOP 1.0. ISO8859-1 is used for char/string, and
// wchar/wstring are illegal.
//
if (giopVersion.equals(GIOPVersion.V1_0) || conn == null)
return;
CodeSetComponentInfo.CodeSetContext codeSetCtx = null;
if (conn.getBroker().getORBData().alwaysSendCodeSetServiceContext() ||
!conn.isPostInitialContexts()) {
// Get the negotiated code sets (if any) out of the connection
codeSetCtx = conn.getCodeSetContext();
}
// Either we shouldn't send the code set service context, or
// for some reason, the connection doesn't have its code sets.
// Perhaps the server didn't include them in the IOR. Uses
// ISO8859-1 for char and makes wchar/wstring illegal.
if (codeSetCtx == null)
return;
CodeSetServiceContext cssc = new CodeSetServiceContext(codeSetCtx);
ctxs.put(cssc);
