JAXB and unmappable character for encoding UTF-8

Using locale specific characters in schema or wsdl (i.e. for documentation purpose) is still quite problematic. Especially if you are using JAXB to generate wsdl2java java classes. Because JAXB uses default system encoding and classes are usually compiled in UTF-8 special chars in java comments resolves in compilations error:

/url/to/file/SomeFile.java:[11,12] unmappable character for encoding UTF-8 A workaround to this problem is to isolate wsdl2java code generation in a dedicated maven module and to configure the compiler plugin to use OS dependant encoding:

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <encoding>${file.encoding}</encoding>
        </configuration>
</plugin>

New HTTP Logger Grails plugin

I've wrote a new Grails plugin - httplogger. It logs:

  • request information (url, headers, cookies, method, body),
  • grails dispatch information (controller, action, parameters),
  • response information (elapsed time and body).

It is mostly useful for logging your REST traffic. Full HTTP web pages can be huge to log and generally waste your space. I suggest to map all of your REST controllers with the same path in UrlMappings, e.g. /rest/ and configure this plugin with this path.

Here is some simple output just to give you a taste of it.

17:16:00,331 INFO  filters.LogRawRequestInfoFilter  - 17:16:00,340 INFO  filters.LogRawRequestInfoFilter  - 17:16:00,342 INFO  filters.LogGrailsUrlsInfoFilter  - 17:16:00,731 INFO  filters.LogOutputResponseFilter  - >> #1 returned 200, took 405 ms.
17:16:00,745 INFO  filters.LogOutputResponseFilter  - >> #1 responded with '{count:0}'

17:18:55,802 INFO  filters.LogOutputResponseFilter  - >> #2 responded with ''
