Re: Unable to send a file using BlobMessage via HTTP transport

2008-02-04 Thread Supriya Prakash 

Hi,

I'm facing the same problem. The publisher sends the message but a
NullPointerException is thrown at subscriber's end on the following line : -
InputStream in = bMsg.getInputStream();

On debugging I found that blobUploader attribute of the Blob message
received is null. Whereas this attribute had the entire content and blob
transfer policy when sent by the publisher.

I am using ActiveMQ 5.0. Any pointers or updates??

Thanks,
supriya

 Code at producer side:

 BlobMessage message = mSession.createBlobMessage(in);
 producer.send(message);
 
 Code at consumer side:
 if (message instanceof BlobMessage) {
 try {
 bMsg = (BlobMessage) message;
   InputStream in = bMsg.getInputStream();
 //Code hang here when I am trying to read InputStream..
 }
 
 can anybody help in this regard?
 
 Thanks in advance!

Did you check your blob repository if the file was successfuly uploaded?
BlobMessageing dosent work out of the box, if you use the binary distribution.
You must download the source and build it by your own. An artifact called 
activemq-fileserver will create an webapp wich can be used to upload the files. 
Install this webapp in a webcontainer (for example in the embedded jetty in 
activemq) an point the blobUpluadUrl to this webapp.

How are you creating the broker?


 Code at producer side:
 ActiveMQSession mSession = (ActiveMQSession) session;
 InputStream in = new FileInputStream(C:/file.txt);
 BlobMessage message = mSession.createBlobMessage(in);
 producer.send(message);

 Code at consumer side:
 if (message instanceof BlobMessage) {
 try {
 bMsg = (BlobMessage) message;
 InputStream in = bMsg.getInputStream();
 //Code hang here when I am trying to read InputStream..

What does the URL look like on the BlobMessage?
