Re: surefire : classloader issue with GWTTestCase
I trie to remove all classpath references from the surefiretmp file, that includes all my dependencies even when useManifestOnlyJar is set to false. I then cannot run the test anymore : org.apache.maven.surefire.booter.SurefireExecutionException: com/google/gwt/junit/client/GWTTestCase; nested exception is java.lang.NoClassDefFoundError: com/google/gwt/junit/client/GWTTestCase - but the required jar is set on command line as -classpath ! I may be wrong, but in [useManifestOnlyJar=false] mode, surefire still uses the tmpFile to load classes, not the command line classpath. 2008/7/25 nicolas de loof <[EMAIL PROTECTED]>: > I also tried to drastically reduce the command line (removing all > unecessary dependencies) but have the same issue. > > > >> 2008/7/25 Jeff MAURY <[EMAIL PROTECTED]>: >> >> Using false may lead to classpath >>> too long for your environment and leading to ClassNotFoundException or >>> ClassNotFoundError.

Re: surefire : classloader issue with GWTTestCase
I tried to copy/paste the command line executed by surefire : java -Xmx256M -classpath blablablablalba org.apache.maven.surefire.booter.SurefireBooter C:\WINDOWS\TEMP\surefire17025tmp C:\WINDOWS\TEMP\surefire17026tmp As surefire executes, it seems the line is not too long (evn it is very long ;-) ) so that the class name argument is used by java to run surefire booter. I then get : @HL @HL--- @HL T E S T S @HL--- @SLRunning com.capgemini.bios.gwt.client.ApplicationITest Starting HTTP on port 0 HTTP listening on port 1538 StandardContext[]Marking servlet shell as unavailable [WARN] StandardWrapperValve[shell]: Allocate exception for servlet shell javax.servlet.ServletException: Class com.google.gwt.dev.shell.GWTShellServlet is not a Servlet I just remembered that gwt-user.jar contains a copy of the servlet-api, that may conflict with my servlet-api.jar declared as a project dependency. But removing this dependency did not change the bad result :-( 2008/7/25 Jeff MAURY <[EMAIL PROTECTED]>: > Using false may lead to classpath > too long for your environment and leading to ClassNotFoundException or > ClassNotFoundError.

Re: surefire : classloader issue with GWTTestCase
Using false may lead to classpath too long for your environment and leading to ClassNotFoundException or ClassNotFoundError. May be this is what you have ?

Re: surefire : classloader issue with GWTTestCase
Using false makes things work better, as the full classpath is scanned for java source files by the GWT compiler, but now I get "javax.servlet.ServletException: Class com.google.gwt.dev.shell.GWTShellServlet is not a Servlet" (looks like a classloader conflict) 2008/7/25 nicolas de loof <[EMAIL PROTECTED]>: > Hello, > > I'm trying to setup surefire plugin to run GWTTestCase.

surefire : classloader issue with GWTTestCase
Hello, I'm trying to setup surefire plugin to run GWTTestCase. This requires some custom setup as the "hosted mode browser" requires GWT to read the java source code : maven-surefire-plugin src/it/java src/main/java gwt.args -out target/www-test -logLevel ALL -Xmx256M Myissue is that - according to GWT log -- GWT does only lookup the surefire.class.path (JRE rt.jar + surefirebooter.jar), and not all other dependencies or additionalClassPathElements. It seems the classloader hierarchy used by surefire that is not supported by GWTTestCase. Any suggestion to get this working ?
