WMB 6.
I have a java compute node that uses a number of classes in the same package (same java project, same jar file, same bar file). One of the classes tries to instantiate a ResourceBundle. The properties file target of the getBundle method is also in the same package.
When I instantiate these classes from the command line (using a class with a main method), the ResourceBundle can be loaded without any problems. However, when the java compute node instantiates these classes in a message flow, I get the following error:
java.util.MissingResourceException: Can't find bundle for base name company.com.SecurityConfig, locale en
I have tried these variations:
ResourceBundle rc = ResourceBundle.getBundle("company.com.SecurityConfig", Locale.ENGLISH, this.getClass().getClassLoader());
ResourceBundle.getBundle("company.com.SecurityConfig", Locale.getDefault());
ResourceBundle.getBundle("company.com.SecurityConfig");
The properties are in company.com.SecurityConfig.properties
Any help would be very much appreciated.
Thank you very much |

How are you deploying the code? Are you putting the jar file in the bar file?
Are you sure that the properties file is being included in the jar file?

Did you look at the Java Compute node sample?

I did. I don't recall seeing sample code for loading ResourceBundles. I will look again. |

Are you sure there is no spelling error on the bundle name?
Should it not be com.company.whatever instead of company.com.whatever...

Yes, and I had other people look just to be extra cautious. In addition, the class has no problem loading the ResourceBundle when it is instantiated from outside the broker (using a class with a main method).

Yes. I changed the package name when I posted this topic. In my haste I wrote company.com instead of com.company. Our standard is actually co.county.Class and co.county.Resource. So, I should have posted co.county.SecurityConfig for the resource and co.county.SecurityConfig.properties for the properties file. |

Yes. I noticed that despite the fact that it appears they put it in the package, they did not fully qualify the resource:
private final static String ROUTING_TABLE_FILE = "routingtable.cfg";
and they used Class.getResourceAsStream
InputStream is = RoutingFileNode.class.getResourceAsStream(ROUTING_TABLE_FILE);
routingTable = new Properties();
routingTable.load(is);
I tried doing it the way the sample did it, and it did not work. This is most confusing! |

Ok back to the drawing board.
To avoid naming problems I usually use getClass().getName().
So the properties need to have the same name as the class.
This does not absolve you, however, from having the jar in which this property file is to be found on the classpath.
On the broker this is deployed, to make sure, you dump the classpath at runtime to know what it is. Then make sure it contains the jar name as
<relative or absolute path>/myjar.jar. In the app you should then be able to access the properties file. The jar may have to be explicitly on the classpath I don't believe that the directory where the jar is will be sufficient.
If nothing else works try extracting from the jar and see if it gets picked up then...
Enjoy

Im facing a similar issue of reading a property file.
Ive tried everything on this site.
My code is as foll-
InputStream is =JavaCompute.class.getResourceAsStream("myservice.cfg");
Properties properties = new Properties();
properties.load(is);
properties.getProperty("valuel");
The cfg file is available in the jar but still is not able to get the value.
Please help!!! |
