id="Camel2.19Release-NewandNoteworthy">New and Noteworthy</h2><p>Welcome to the
2.19.0 release which approx XXX issues resolved (new features, improvements and
bug fixes such as...)</p><ul><li>The <a shape="rect"
href="camel-maven-plugin.html">Camel Maven Plugin</a> now provides the
<code>camel:validate</code> goal to parse your Java and XML source code for any
Camel routes and report invalid Camel endpoint uri and simple expression
errors. You can run this at code time (not run
time). </li><li>Introduced a
new <code>camel-catalog-rest</code> artifact which is a tiny
standalone REST API of the CamelCatalog using JAX-RS and Swagger
Annotations.</li><li>Added <code>camel-catalog-rest-app</code> as a
standalone application which used Apache CXF with Jetty to host the Catalog
REST API with embedded Swagger
UI</li><li>Returning <code>null</code> from <a shape="rect"
href="bean.html">Bean</a> should work similar to
how <code>setBody</code> and <code>transform</code> works
when they set a <code>null</code> body.</li><li>The Camel Spring Boot
starter components now have their auto configuration depends
on <code>org.apache.camel.springboot.CamelAutoConfiguration</code> which
makes it easier writing unit tests where you can
exclude <code>org.apache.camel.springboot.CamelAutoConfiguration</code> to
turn off Camel Spring Boot auto configuration completely.</li><li>Camel now
supports OWASP d
ependency check maven plugin</li><li>Camel-Nats component now supports
TLS</li><li>Camel-Nats component now supports explicit flushing (with timeout)
of the connection</li><li>Camel-Metrics component now supports Gauge
type</li><li><a shape="rect" href="file2.html">File consumer</a> now
supports idempotent-changed and idempotent-rename read lock strategies for
clustering. </li><li>Camel Catalog now supports custom runtime providers
that only includes the supported Camel components, languages and data formats
running in that container. For example for Karaf or Spring Boot in the
camel-catalog-provider-karaf and
camel-catalog-provider-springboot.</li><li>The <a shape="rect"
href="https://cwiki.apache.org/confluence/display/WW/bean";>bean</a> component
will when calling a method that returned an instance of
<code>Callable</code> now call that callable to obtain the chained result.
This allows to call Groovy functions/closures etc.</li><li>Failover <a
shape="rect
" href="load-balancer.html">Load Balancer</a> with inheritErrorHandler=false,
now allows Camel's <a shape="rect" href="error-handler.html">Error
Handler</a> to react after the load balancer is exhausted.</li><li><a
shape="rect" href="salesforce.html">Salesforce</a> component now supports
limits, recent items, approvals and composite API</li><li>Dumping Camel routes
as XML now includes custom namespaces which are at xpath expressions etc.
Likewise updating Camel routes from XML can now include namespaces which will
be associated on xpath
expressions.</li><li>Added <code>RouteIdFactory</code> which can auto
assign route ids based on the consumer endpoints to use more sensitible names,
instead of route1, route2, etc.</li><li><code>RouteBuilder</code>
auto-configuration can now be disabled in <a shape="rect" href="cdi.html">Camel
CDI</a></li></ul><p>Fixed these issues</p><ul><li>Fixed starting Camel on
Oracle JDK 1.8.0_19 or lower, which would throw an UnsupportedOperatio
nException</li><li>Fixed <a shape="rect" href="hystrix-eip.html">Hystrix
EIP</a> to also execute fallback if execution was rejected or short-circuited
or other reasons from Hystrix. </li><li>Fixed adding new routes to running
CamelContext and if the new routes would fail to startup, then before these
routes would "hang around". Now only succesful started routes are
added.</li><li>Adding or removing routes that starts from <a shape="rect"
href="undertow.html">Undertow</a> no longer restart the entire HTTP
server</li><li><a shape="rect" href="vm.html">VM</a> endpoint should prepare
exchange with the CamelContext from the consumer and not from cached endpoint
which can be different</li><li>Fixed a bug when using <a shape="rect"

closed exception when using <a shape="rect" href="bean.html">Bean</a> in

an issue when using <code>pipeline</code> in Java DSL not setting up the
EIP correctly which could lead to runtime route not as
intended.</li><li>Fixed <a shape="rect" href="dropbox.html">Dropbox</a> to
use <a shape="rect" href="stream-caching.html">Stream caching</a> to avoid
reading entire file into memory so Camel can process big
files</li><li>Fixed <code>toD</code> issue with splitting uris when RAW

id="Simple-SimpleExpressionLanguage">Simple Expression Language</h2><p>The
Simple Expression Language was a really simple language when it was created,
but has since grown more powerful. It is primarily intended for being a really
small and simple language for evaluating <a shape="rect"
href="expression.html">Expression</a>s and <a shape="rect"
href="predicate.html">Predicate</a>s without requiring any new dependencies or
knowledge of <a shape="rect" href="xpath.html">XPath</a>; so it is ideal for
testing in <strong><code>camel-core</code></strong>. The idea was to cover 95%
of the common use cases when you need a little bit of expression based script
in your Camel routes.</p><p>However for much more complex use cases you are
generally recommended to choose a more expressive and powerful language such
as:</p><ul><li><a shape="rect" href="spel.html">SpEL</a></li><li><a

href="scripting-languages.html">Scripting Languages</a></li></ul><p>The simple
language uses <strong><code>${body</code>}</strong> placeholders for complex
expressions where the expression contains constant
literals.</p><p><strong>Deprecated</strong>: The <strong><code>${
}</code></strong> placeholders can be omitted if the expression starts with the
token, or if the token is only itself.</p><div

Changes in Camel 2.9 onwards</p><span class="aui-icon aui-icon-small

class="confluence-information-macro-body"><p>The <a shape="rect"
href="simple.html">Simple</a> language have been improved from Camel 2.9 to use
a better syntax parser, which can do index precise error messages, so you know
exactly what is wrong and where the problem is. For example if you have made a
typo in one of the operators, then previously the parser would not be able to
detect this, and cause the evaluation to be true. There are a few changes in
the syntax which are no longer backwards c
ompatible. When using <a shape="rect" href="simple.html">Simple</a> language
as a <a shape="rect" href="predicate.html">Predicate</a> then the literal text
<strong>must</strong> be enclosed in either single or double quotes. For
example: <code>"<strong>${body} == 'Camel'</strong>"</code>. Notice how we have
single quotes around the literal. The old style of using
<code>"<strong>body</strong>"</code> and
<code>"<strong>header.foo</strong>"</code> to refer to the message body and
header is <strong><code>@deprecated</code></strong>, and it is encouraged to
always use <strong><code>${ }</code></strong> tokens for the built-in
functions.<br clear="none"> The range operator now requires the range to be in
single quote as well as shown: <code>"<strong>${header.zip} between
'30000..39999'</strong>"</code>.</p></div></div><p>To get the body of the in
message: <strong><code>body</code></strong>, or
<strong><code>in.body</code></strong> or
<strong><code>${body}</code></strong>.</p><p>A co
mplex expression must use <strong><code>${ }</code></strong>
placeholders, such as: <strong><code>Hello ${in.header.name} how are
you?</code></strong>.</p><p>You can have multiple functions in the same
expression: <code>"<strong>Hello ${in.header.name} this is ${in.header.me}
speaking</strong>"</code>. However you can <em><strong>not</strong></em> nest
functions in Camel 2.8.x or older e.g., having another <strong><code>${
}</code></strong> placeholder in an existing, is not allowed. From
<strong>Camel 2.9</strong> you can nest functions.</p><h3
