Subject [jira] Updated: (AMQ-1308) Messages delivered from HttpTunnelServlet connected broker are limited to 64K bytes.
Date Fri, 27 Jul 2007 16:06:48 GMT

     [ https://issues.apache.org/activemq/browse/AMQ-1308?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eddie Epstein updated AMQ-1308:
-------------------------------

    Attachment: HttpProblems.patch

Turns out there is another bug: the HTTP connector is completely broken for multi-byte UTF-8
characters. The attached patch file includes fixes for both the 64K limit (same fix as previously
submitted) and for the bad decode of the Http request body.

>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Transport
>    Affects Versions: 4.1.1

> In TextWireFormat.java: the methods writeUTF/readUTF are used in the code path to deliver
messages from an HTTP connected broker.
>     public void marshal(Object command, DataOutput out) throws IOException {
>         out.writeUTF(marshalText(command));
>     }
>     public Object unmarshal(DataInput in) throws IOException {
>         String text = in.readUTF();
>         return unmarshalText(text);
> 	}
> These methods limit the max message size to 64K. Messages sent to an HTTP connected broker
do not have the same limitation.
> Problem first reported in activemq-users with the subject "UTFDataFormatException in
broker when using a http transportConnector".
> THanks,
