hmm....so here is what happened.
I tried to follow your first solution of modifying the class path of the web
module. But eclipse did not recognize the hello_rest module because I had
not set it as a java project. So I deleted the project and started a new
java project and followed the instructions again provided at
http://docs.geoserver.org/1.7.x/developer/programming-guide/rest-services/implementing.html
There were some errors like:
*
*
>
> *The declared package "org.geoserver.hellorest" does not match the
> expected package "src.main.java.org.geoserver.hellorest"
> HelloResource.java hello_rest/src/main/java/org/geoserver/hellorest
> line 1 Java Problem
> *
*The import org.geoserver cannot be resolved HelloResource.java
> hello_rest/src/main/java/org/geoserver/hellorest line 4 Java Problem
> *
*The import org.restlet cannot be resolved HelloResource.java
> hello_rest/src/main/java/org/geoserver/hellorest line 6 Java Problem
> *
>
But I did the mvn install and the build was successful. I added the module
to the web module's classpath and restarted the geoserver by running the
Start.java file under web/src/test/java/org/vfny/geoserver/jetty/. But the
http requests,
http://localhost:8080/geoserver/rest/hello_rest/hello.txt
http://localhost:8080/geoserver/rest/hello_rest
still return the exception.
I also tried running a separate local geoserver. So I installed geoserver
1.7.6 and then added the hello_rest-1.7.5-SNAPSHOT.jar file in the
WEB-INF/lib folder. I sensed it would not work becasue the versions are
different. When I sent the http requests it returned no exceptions. All that
the page returned was "Geoserver Configuration API". I checked the log and
it seems that the request was successful:
*0:0:0:0:0:0:0:1 - - [17/Aug/2009:14:49:20 +0000] "GET
/geoserver/rest/hello_rest/hello.txt HTTP/1.1" 200 138
0:0:0:0:0:0:0:1 - - [17/Aug/2009:15:01:38 +0000] "GET
/geoserver/rest/hello_rest HTTP/1.1" 200 138*
Does this mean the module was integreated successfully? I thought the
request was supposed to return the test "Hello World"
