Dawid Wróbel created AMQ-4218:
---------------------------------
Summary: JMS selector statement not displayed correctly in
subscribers web vew if contains XML-prohibited characters
Key: AMQ-4218
URL: https://issues.apache.org/jira/browse/AMQ-4218
Project: ActiveMQ
Issue Type: Bug
Affects Versions: 5.7.0
Reporter: Dawid Wróbel
Priority: Minor
The issue reported affects two similar use cases:
* XML view of JMS subscribers is rendered with syntax errors if any of the
subscribers has a selector containing an XML-prohibited character in its
statement, e.g. {{PROPERTY <> VALUE}} selector statement contains {{<}} and
{{>}} characters that cause XML syntax errors
* HTML view of JMS subscribers does not properly display the selector statement
if it contains any of the XML-prohibited characters in it, e.g. {{PROPERTY <>
VALUE}} will be displayed as {{PROPERTY VALUE}} - both the {{<}} and {{>}}
characters are stripped out
The solution is to use the {{<c:out value=""/>}} syntax whenever an
XML-unescaped string is to be outputted - the {{c:out}} has the {{escapeXml}}
property set to {{true}} by default which does the trick.
I have attached the patch that fixes the XML escaping for JMS selector.
Please note that I could not find any JMS naming specification to make sure
whether the JMS selector is the only field that is allowed to contain
XML-prohibited characters. Therefore I would advise the patch reviewer to
figure out whether this fix should also be applied to JMS Client ID,
Connection ID, Destination Name and Subscription name fields.
