MQSeries.net :: View topic - Issues with PDF images

Hi, we are experiencing problems with reading pdf files that contain images, here is what we do -

MQ reads the file
file is picked up by a java application which writes the file out again to a local directory.
When we open the output pdf file we get errors as the image has not been translated.
This is a Windows/NT platform.

What is happening is that the pdf files contain image data which is made up of non-ascii characters. When the file is written out these characters do not translate properly and so end up as question marks and hence we get an error when trying to open the pdf file written out.

We are in the UK.

I am thinking that this is a character set/encoding problem but despite trying a multitude of different values for the character set in our java code we have not been able to fix the problem.

The java code sets the character set at the point it defines the MQ message. There are 2 parameters - encoding and characterset. These were originally set to 273 and 0 respectively. The 0 means it will take the value from the Queue Manager which is currently set to 850.

We have tried setting the value in the java code to 1252, 1208 plus a few others, without success.

What I am not clear about is whether it would make any difference re-defining the Queue Manager specifying the value there - I think that the java code overrides the setting of the queue manager but I'm not entirely sure of this.

We need to translate data which includes hex values such as '9C'.

I would be grateful for any advice/pointers.

Thanks in advance.
