Xerces Serialize XML data and encoding

the next code works fine on Xerces 2.6 - helper function to convert bytes  to utf8 format.

void convertToUTF8(const XMLCh* buffer, CString &utf8_string)

{

XMLTranscoder* utf8Transcoder;

XMLTransService::Codes failReason;

utf8Transcoder = XMLPlatformUtils::fgTransService->makeNewTranscoderFor("UTF-8", failReason, 16*1024);

size_t len = XMLString::stringLen(buffer);

XMLByte* utf8 = new XMLByte[(len*MB_LEN_MAX)+1];

unsigned int eaten;

unsigned int utf8Len = utf8Transcoder->transcodeTo((buffer), len, utf8, len*MB_LEN_MAX, eaten, XMLTranscoder::UnRep_Throw);

utf8[utf8Len] = '\0';

utf8_string = (char*)utf8;

delete[] utf8;

delete utf8Transcoder;

}

SAVING CHANGES IS NOT PERMITTED - SQL Server Management Studio

if you get such error on every table changes:
Saving changes is not permitted. The changes you have made require the following tables to be dropped and re-created. You have either made changes to a table that can't be re-created or enabled the option Prevent saving changes that require the table to be re-created.

on the  Management Studio -> go to Tools -> Options then go to the Designer Page and uncheck "Prevent saving changes that require table re-creation".

WebSphere MQ Queue Load / Unload Utility

here you can find a very good utility from IBM to use with MQ product.

Possible Uses:

• To save the messages that are on a queue, to a file, perhaps for archiving purposes and the possibility of later reload back onto a queue.

• To reload a queue with messages you previously saved to a file.

• To remove messages from a queue which are old.

• To ‘replay’ test messages from a stored location – even maintaining time spacing if required.

WebSphere "IBM End user tried to act as a CA"

When i tried to access a secured web services i get the next error:

org.apache.axis2.AxisFault: Connection has been shutdown: javax.net.ssl.SSLHandshakeException: com.ibm.jsse2.util.h: End user tried to act as a CA

at org.apache.axis2.AxisFault.makeFault(AxisFault.java:430)

at org.apache.axis2.transport.http.SOAPMessageFormatter.writeTo(SOAPMessageFormatter.java:83)

at org.apache.axis2.transport.http.AxisRequestEntity.writeRequest(AxisRequestEntity.java:84)

at org.apache.commons.httpclient.methods.EntityEnclosingMethod.writeRequestBody(EntityEnclosingMethod.java:499)

the CA in this case is Entrust company.

after some hours , i found the next article that helped me to solved it out , and this way i understood i am not alone here.

the fix is described here:

IBM End user tried to act as a CA - United States.

summery:

update the java.security file , set the

ssl.TrustManagerFactory.algorithm to use IbmPKIX insteaf of IbmX509 .

this article gave me the clue that its somthing with entrust CA as well

and restart your server.
