Hi all,
I'm trying to migrate my camel routes from an older karaf using Spring-DM
to a newer one using Blueprint. For this, I intend to import my spring XML
configuration in my blueprint XML file. The camel context is defined in the
blueprint XML file.
Currently I'm stuck with a placeholder issue. I'm trying to import some
configuration properties from OSGI environment which are stored in a few
files under the ${karaf.home}/etc directory.
I tried many ways according to this documentation page (
https://camel.apache.org/components/2.x/properties-component.html), but
still not getting the functionality which I want.
On short, I want to be able to define in my XML files (blueprint, spring)
some default values for some properties, overriding them with the
configurations found in the configuration files from ${karaf.home}/etc/ and
be able to use them in in both blueprint XML and spring XML files.
Preferable by ${variableName}.
Currently, I did this:
Blueprint XML:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:bean="http://www.springframework.org/schema/beans";
xmlns:camel="http://camel.apache.org/schema/spring";
xmlns:osgix="http://www.springframework.org/schema/osgi-compendium";
xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.0.0";
xsi:schemaLocation="

</cm:property-placeholder>

</route>
</camelContext>
</blueprint>
<beans xmlns="http://www.springframework.org/schema/beans";

xmlns:ctx="http://www.springframework.org/schema/context";
xsi:schemaLocation="http://www.springframework.org/schema/beans

<beans>
<bean id="bridgePropertyPlaceholder"
class="org.apache.camel.spring.spi.BridgePropertyPlaceholderConfigurer">
</bean>
...accessing ${configVarHere2}
</beans>
</beans>
I get this kind of error (because of spring XML):
Failed to convert property value of type 'java.lang.String' to required
type 'int' for property 'configPropName'; nested exception is
java.lang.NumberFormatException: For input string: "${configProprName}"
after I get a few messages like:
The property placeholder processor for ${, } in bundle
bundleName/BundleVersion found an immutable Constructor Argument at
location Bean named beanName->Argument index -1 and value type null->. This
may prevent properties, beans, or other items referenced by this component
from being properly processed.
Any idea how I can solve my issue?
Thanks,
Mura Andrei
