launchConfiguration issue for GWT 2.7.0 (New to GWT)

I am migrating from GWT 1.7.0 to GWT 2.7.0

My GWT 1.7.0 launch configuration ( from MmseaApp.launch file)

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<launchConfiguration type="org.eclipse.jdt.launching.localJavaApplication">
<listAttribute key="org.eclipse.debug.core.MAPPED_RESOURCE_PATHS">
<listEntry value="/MmseaApp"/>
</listAttribute>
<listAttribute key="org.eclipse.debug.core.MAPPED_RESOURCE_TYPES">
<listEntry value="4"/>
</listAttribute>
<booleanAttribute key="org.eclipse.debug.core.appendEnvironmentVariables" value="true"/>
<listAttribute key="org.eclipse.jdt.launching.CLASSPATH">
<listEntry value="&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;&#13;&#10;&lt;runtimeClasspathEntry containerPath=&quot;org.eclipse.jdt.launching.JRE_CONTAINER&quot; javaProject=&quot;MmseaApp&quot; path=&quot;1&quot; type=&quot;4&quot;/&gt;&#13;&#10;"/>
<listEntry value="&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;&#13;&#10;&lt;runtimeClasspathEntry internalArchive=&quot;/MmseaApp/src&quot; path=&quot;3&quot; type=&quot;2&quot;/&gt;&#13;&#10;"/>
<listEntry value="&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;&#13;&#10;&lt;runtimeClasspathEntry id=&quot;org.eclipse.jdt.launching.classpathentry.defaultClasspath&quot;&gt;&#13;&#10;&lt;memento project=&quot;MmseaApp&quot;/&gt;&#13;&#10;&lt;/runtimeClasspathEntry&gt;&#13;&#10;"/>
<listEntry value="&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;&#13;&#10;&lt;runtimeClasspathEntry externalArchive=&quot;C:/gwt 1.7.0/gwt-windows-1.7.0/gwt-dev-windows.jar&quot; path=&quot;3&quot; type=&quot;2&quot;/&gt;&#13;&#10;"/>
</listAttribute>
<booleanAttribute key="org.eclipse.jdt.launching.DEFAULT_CLASSPATH" value="false"/>

<stringAttribute key="org.eclipse.jdt.launching.MAIN_TYPE" value="com.google.gwt.dev.GWTShell"/>
<stringAttribute key="org.eclipse.jdt.launching.PROGRAM_ARGUMENTS" value="-out www mmsea/app.jsp&#10;-noserver&#10;-port 9080"/>

<stringAttribute key="org.eclipse.jdt.launching.PROJECT_ATTR" value="MmseaApp"/>
<stringAttribute key="org.eclipse.jdt.launching.VM_ARGUMENTS" value="-Xmx256M"/>
</launchConfiguration>

I need help in rewriting/changing the above 2 lines in red text for migrating to GWT 2.7.0 ;

Below are the errors I am getting;

1. Exception in thread "main" java.lang.NoClassDefFoundError: com.google.gwt.dev.GWTShell
   Caused by: java.lang.ClassNotFoundException: com.google.gwt.dev.GWTShell
       at java.net.URLClassLoader.findClass(URLClassLoader.java:423)
       at java.lang.ClassLoader.loadClass(ClassLoader.java:660)
       at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:346)
       at java.lang.ClassLoader.loadClass(ClassLoader.java:626)
2. Unknown argument: -out

Looks like 'com.google.gwt.dev.GWTShell' is deprecated. What is the replacement code for this in GWT 2.7.0 ?

Any help would be greatly appreciated.

Thanks a lot in advance.
