This chapter continues from where Creating the workspace definition left us.

Defining a web archive (war)

~/iwant-tutorial $ $EDITOR "as-iwant-tutorial-developer/i-have/wsdefdef/src/main/java/com/example/wsdefdef/IwantTutorialWorkspaceProvider.java"
package com.example.wsdefdef;
import net.sf.iwant.api.javamodules.JavaSrcModule;
import net.sf.iwant.api.wsdef.IwantWorkspaceProvider;
import net.sf.iwant.api.wsdef.WorkspaceDefinitionContext;
public class IwantTutorialWorkspaceProvider implements IwantWorkspaceProvider {
@Override
public JavaSrcModule workspaceModule(WorkspaceDefinitionContext ctx) {
return JavaSrcModule.with().name("iwant-tutorial-wsdef")
return JavaSrcModule
.with()
.name("iwant-tutorial-wsdef")
.locationUnderWsRoot("as-iwant-tutorial-developer/i-have/wsdef")
.mainJava("src/main/java").mainDeps(ctx.iwantApiModules())
.mainDeps(ctx.wsdefdefModule()).end();
.mainDeps(ctx.wsdefdefModule())
.mainDeps(ctx.iwantPlugin().war().withDependencies()).end();
}
@Override
public String workspaceClassname() {
return "com.example.wsdef.IwanttutorialWorkspace";
}
}

We have to generate Eclipse settings before editing the workspace definition.

~/iwant-tutorial $ as-iwant-tutorial-developer/with/bash/iwant/side-effect/eclipse-settings/effective

( .settings/org.eclipse.jdt.ui.prefs)

Now we define a war target using iwant-plugin-war.

~/iwant-tutorial $ $EDITOR "as-iwant-tutorial-developer/i-have/wsdef/src/main/java/com/example/wsdef/IwanttutorialWorkspace.java"
package com.example.wsdef;
import java.util.Arrays;
import java.util.List;
import net.sf.iwant.api.core.Concatenated;
import net.sf.iwant.api.core.Concatenated.ConcatenatedBuilder;
import net.sf.iwant.api.core.HelloTarget;
import net.sf.iwant.api.model.Path;
import net.sf.iwant.api.model.SideEffect;
import net.sf.iwant.api.model.Source;
import net.sf.iwant.api.model.Target;
import net.sf.iwant.api.wsdef.IwantWorkspace;
import net.sf.iwant.api.wsdef.SideEffectDefinitionContext;
import net.sf.iwant.eclipsesettings.EclipseSettings;
import net.sf.iwant.plugin.war.War;
public class IwanttutorialWorkspace implements IwantWorkspace {
@Override
public List<? extends Target> targets() {
return Arrays.asList(new HelloTarget("hello", "hello from iwant\n"));
return Arrays.asList(new HelloTarget("hello", "hello from iwant\n"),
demoWar());
}
private static Target demoWar() {
return War.with().name("demo.war").basedir(Source.underWsroot("web"))
.webXml(webXml()).end();
}
private static Path webXml() {
ConcatenatedBuilder webXml = Concatenated.named("web.xml");
webXml.string("<web-app>\n");
webXml.string("\n");
webXml.string(" <display-name>webapp</display-name>\n");
webXml.string("\n");
webXml.string(" <!-- etc -->\n");
webXml.string("</web-app>\n");
return webXml.end();
}
@Override
public List<? extends SideEffect> sideEffects(
SideEffectDefinitionContext ctx) {
return Arrays
.asList(EclipseSettings
.with()
.name("eclipse-settings")
.modules(ctx.wsdefdefJavaModule(),
ctx.wsdefJavaModule()).end());
}
}

We create the base directory to be warred.

~/iwant-tutorial $ mkdir web
~/iwant-tutorial $ echo "hello" > index.html

Finally we list the content of the war file.

~/iwant-tutorial $ as-iwant-tutorial-developer/with/bash/iwant/list-of/targets
(0/1 S~ net.sf.iwant.api.javamodules.JavaClasses iwant-tutorial-wsdef-main-classes)
