does JWS support to launch One-Jar - resources

Can I supposed to launch One-Jar using JWS? One-JAR provides custom classloader that knows how to load classes and resources from a jars inside an archive whereas in JWS we need to specify each JAR that is being used in resources.
What I supposed to specify in JNLP if I am trying to launch One-Jar -
<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" codebase="" href="">
<information>
<title>Application</title>
<vendor>ABC</vendor>
</information>
<resources>
<!-- Application Resources -->
<j2se version="1.5+"
href="http://java.sun.com/products/autodl/j2se"/>
<jar href="Application.jar" main="true" download="eager" />
</resources>
<application-desc main-class="com.simontuffs.onejar.Boot">
</application-desc>
<update check="background"/>
<security>
<all-permissions/>
</security>
</jnlp>
My Application JAR that is One-JAR contains -
com\simontuffs\onejar\<contains complied classes> like JarClassLoader$1.class etc
lib/<contains all jar>
OneJar.class
main/<my application's jar>
META-INF\MANIFEST.MF\ <contains >
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.8.1
Created-By: One-Jar 0.96 Ant taskdef
Main-Class: com.simontuffs.onejar.Boot
One-Jar-Main-Class: com.application.main.Entry
Name: com/simontuffs/onejar/Boot$3.class
SHA1-Digest: +LPrezs+UEFcE3J7QvumcAEO8Z0=
Name: OneJar.class
SHA1-Digest: 28pzzJWqEpLk1xFwJ/jsAav8LyI=
Name: lib/commons-io-1.4.jar
SHA1-Digest: qHYtB+ds/eI5Ulel2ke6fB29Pc4=
etc..etc..
How to specify these com/simontuffs/onejar/Boot$3.class paths in resource ?

Part of the problem of supporting tools like One-Jar is that loading Jars within Jars requires a custom class-loader. By default JWS will use the usual JRE class-loaders - which do not support it.
There are two possible ways that you might get around that (that I know of).
1. Get access to the custom class-loader.
Get an instance of the custom loader used by One-Jar and set it as the context class-loader. This would require a trusted app., but I get the impression that your app. is trusted.
I have no idea if the One-Jar API provides this loader for your own app.'s use.
2. Use some options when building.
From Options and VM Properties..
one-jar.jar.names
true: Recorded classes are kept in directories corresponding to their jar names.
false: Recorded classes are flattened into a single directory.
Duplicates are ignored (first wins)
The 2nd option sounds like a standard 'fat jar'. That should work with the conventional (default) class-loader used by JWS.

Javascript fast load does not work in Liferay on WebLogic

I have deployed Liferay 6.2 GA4 portal on WebLogic server 10.3.6.0. If the javascript.fast.load property is enabled, the packed javascript version is not got (downloaded) from /combo url. In web browser console the following errors are displayed:
GET https://www.mywebsite.cz/liferay-portal/combo/?browserId=other&minifierType=&languageId=en_US&b=6203&t=1448975784000&/liferay-portal/html/js/aui/color-base/color-base-min.js&/liferay-portal/html/js/aui/event-touch/event-touch-min.js&/liferay-portal/html/js/liferay/dockbar.js 404 (Not Found)
Uncaught TypeError: Cannot read property 'init' of undefined
Due to this for example dockbar doesn't work. From source code it looks like ComboServlet can't get servlet resources found in /combo url parameters. If javascript.fast.load is disabled, portal seems to work.

Does anybody know what could be the problem? Some WebLogic or Liferay settings? Thanks for any idea or help.
I've had a comparable problem long ago on tomcat when there were problems with the temporary file path - e.g. it growing too long. This might happen in a deeply nested filesystem, or when the total path length is limited.
One of the path-length-limiting factors that I'm aware of is an encrypted home folder on Linux. Also, if the temporary filesystem runs full, the compressed file won't be written and consequently can't be served to the browser.
Check something along those lines, and please report back.
After several days of solving the problem I found the main cause of this problem was this:
Because the customer didn't want to have portal dependencies (portal-service.jar, portlet-api.jar, ...) as domain libraries, I deployed it as Java EE Shared Libraries. Obviously it works differently than I expected. So after persuasion of customer, I put liferay dependencies to domain lib folder and suddenly everything started to work.

WebSphere Liberty profile JAXBContext ClassCastException

I am using the WebSphere Liberty Profile server, version 8.5.5.3. I have an ear containing multiple wars. I deploy them all exploded (ear and the war's of the modules inside it as well).
When deploying it I get the following class cast exception:
java.lang.RuntimeException: javax.xml.bind.JAXBException:
ClassCastException: attempting to cast bundleresource://67.fwk-1166858817/javax/xml/bind/JAXBContext.class
to jar:file:/C:/ws/IBM/java_1.7_64/jre/lib/rt.jar!/javax/xml/bind/JAXBContext.class.
Please make sure that you are specifying the proper ClassLoader.
I figured that the problem is that my bundled jax-api and jaxb-impl jars are not loaded, so I added to the server.xml the parentLast class loading option:
<enterpriseApplication id="ear-app" location="C:/ws/ear/exploded/ear-app.ear" name="ear-app" >
<classloader delegation="parentLast" commonLibraryRef="provided-jars" privateLibraryRef="shared-libs"/>
</enterpriseApplication>
I added my jax-api and jax-impl jars to this folder
<library id="shared-libs">
<fileset dir="${server.config.dir}/lib/global" include="*.jar"/>
</library>
However I still have the ClassCastException, it looks like it is still using the parentFirst classloading?
I found other jaxb ClassCastException threads, but not when using the Liberty profile..
Maybe it is a typo, but in your post you have delegation="parentFirst" instead of parentLast.
Did you check to just change delegation for application like this:
<enterpriseApplication id="ear-app" location="C:/ws/ear/exploded/ear-app.ear" name="ear-app" >
<classloader delegation="parentLast"/>
</enterpriseApplication>
For more details see Overriding a provided API with an alternative version
I worked aroud the problem by not using the parentLast. Thanks for the help.

Adding script maps during installation of web application IIS

has anyone successfully added IIS script maps to their Wix installation. I have been using this:
<CustomAction Id="AddHandlers_Cmd" Property="AddHandlers" Value=""[SystemFolder]inetsrv\appcmd" set config -section:system.webServer/handlers /+"[\[]name='GSOAP',path='*.dll', verb='*',modules='IsapiModule',scriptProcessor='[BIN]mod_gsoap.dll',resourceType='File', requireAccess='Execute'[\]]"" Execute="immediate"/>
<CustomAction Id="AddHandlers" BinaryKey="WixCA" DllEntry="CAQuietExec" Execute="deferred" Return="check" Impersonate="no"/>
However I get the 404 errors from my web application and when I add the script map manually after installing the application it works perfectly. I would appreciate if anyone could share how they done this.
It sounds like you need to add handler mapping to your web application. If that's the case, then you don't need a custom action to accomplish this.
Take a look at WebApplicationExtension element.
We are writing a separate Custom action in C# and Schedule it in after install Finalize to add handlers.
Try this, you can do anything with your own custom action.
I haven't worked with GSOAP handler, but used ASP.NET ISAPI extention. I suppose basically it has the same level of integration. I will post the code for ASP.NET and I hope you won't have problem with changing it to GSOAP. I have a huge risk of changing something incorrectly and make the examples unusable for you, so I let you do it better.
Here is my code to register extention itself if it isn't
<Component Id="Iis6ConfigExtentions" Guid="{GuidHash({ProductId}-1822E4F3-5850-47D5-9281-D1E0E20C77D4)}" KeyPath="yes" Permanent="yes">
<Condition><![CDATA[Installed OR (IISMAJORVERSION AND (IISMAJORVERSION = "#6"))]]></Condition>
<iis:WebServiceExtension Id="ExtensionASP4" Group="ASP.NET v4.0.30319" Allow="yes" File="[FRAMEWORKROOT]v4.0.30319\aspnet_isapi.dll" Description="ASP.NET v4.0.30319"/>
</Component>
and for adding those to the concrete site you need to use WebApplicationExtention, as #Yan already mentioned:
<iis:WebApplication Id="IIS6WebApp" Name="[SITE_APP_NAME]" WebAppPool="AppPool" >
<iis:WebApplicationExtension Verbs="GET,HEAD,POST" CheckPath="no" Script="yes" Executable="[FRAMEWORKROOT]v4.0.30319\aspnet_isapi.dll" />
</iis:WebApplication>
The CheckPath="no" is required on IIS 6 because we use ASP.NET MVC which doesn't map urls to files on disk. You might need it too since service address probably doesn't map to physical file.
UPDATE:
Looks like it is really not possible to do it directly in WIX (at least in 3.5 version). You are going in right direction - custom action using appcmd. But the provided custom actions aren't complete or what you need: the first one just sets property value to the command you need to execute and the second one calls some Dll custom action which wasn't provided.
What I'd try to execute is:
<CustomAction Id="AddGsoapHandler" Directory="TARGETDIR" Impersonate="no" Execute="deferred" Return="check" ExeCommand="[SystemFolder]inetsrv\appcmd.exe set config -section:system.webServer/handlers /+"[\[]name='GSOAP',path='*.dll', verb='*',modules='IsapiModule',scriptProcessor='[BIN]mod_gsoap.dll',resourceType='File', requireAccess='Execute'[\]]" /commit:apphost" />
Please pay attention to the path attribute of your handler configuration. It will limit handler usage to only URL's which ends with ".dll" - I just copied it from your code but not sure if you've done it intentionally or just copied from example at Microsoft site. That might have led to 401 error even if handler is registered successfully.
Also I added the /commit:apphost argument. Not sure if you really need this, but I use it to explicitly specify that I need to configure my application's config.
UPDATE 2:
If you need to set configuration to only single application, you should specify application object as argument of appcmd instead of the 'config' which means global configuration. Please try this:
<CustomAction Id="AddGsoapHandler" Directory="TARGETDIR" Impersonate="no" Execute="deferred" Return="check" ExeCommand="[SystemFolder]inetsrv\appcmd.exe set app "MySite/app1" -section:system.webServer/handlers /+"[\[]name='GSOAP',path='*.dll', verb='*',modules='IsapiModule',scriptProcessor='[BIN]mod_gsoap.dll',resourceType='File', requireAccess='Execute'[\]]" /commit:apphost" />

Externalizing Tomcat webapp config from .war file

I am having trouble with configuring a webapp in Tomcat 7. In my WAR file, there is a properties file myApp/WEB-INF/classes/myProps.props, and it contains environment-specific properites. I am trying to override that configuration file on the server, so that the same WAR file will deploy to multiple environments.
I heard there was a way to do this using replacement config files in tomcat/conf/Catalina/myApp. This is the method I am having trouble figuring out.
Also, myApp.war is one of many running on the same Tomcat server, and it does not run as localhost. I want to be able to solve this problem for several of the webapps.
Server version: Apache Tomcat/7.0.23
Server built: Nov 20 2011 07:36:25
Server number: 7.0.23.0
OS Name: Linux
Your tomcat/conf/Catalina/<host> can contain context descriptors that let you configure lots of things including defining "environment entries", which are accessible from Java via JNDI. There are lots of ways to go about using it. Personally, I set an environment entry which is the file system path to my properties file. My app is built to check for this entry, and if it doesn't exist, look for the file on the classpath instead. That way, in dev, we have the dev properties right there on the classpath, but when we build and deploy, we point it to an external file.
There's good documentation for configuring a context on the Tomcat website. See the Defining a Context section on details of how to create the file and where to put it.
As an example, if your host is named myHost and your app is a war file named myApp.war in the webapps directory, then you could create tomcat/conf/Catalina/myHost/myApp.xml with this content:
<Context>
<Environment name="configurationPath" value="/home/tomcat/myApp.properties" type="java.lang.String"/>
</Context>
Then from your code, you'd do a JNDI lookup on java:comp/env/configurationPath (95% certainty here) to get that string value.
I like .properties files instead of
JNDI - why build complex object during program configuration instead of initialization time?
system properties - you can't separately configure several instances of same WAR in single Tomcat
context parameters - they accessible only in javax.servlet.Filter, javax.servlet.ServletContextListener which my be inconvenient
Tomcat 7 Context hold Loader element. According to docs deployment descriptor (what in <Context> tag) can be placed in:
$CATALINA_BASE/conf/server.xml - bad - require server restarts in order to reread config
$CATALINA_BASE/conf/context.xml - bad - shared across all applications
$CATALINA_BASE/work/$APP.war:/META-INF/context.xml - bad - require repackaging in order to change config
$CATALINA_BASE/work/[enginename]/[hostname]/$APP/META-INF/context.xml - nice, but see last option!!
$CATALINA_BASE/webapps/$APP/META-INF/context.xml - nice, but see last option!!
$CATALINA_BASE/conf/[enginename]/[hostname]/$APP.xml - best - completely out of application and automatically scanned for changes!!!
Context can hold custom Loader org.apache.catalina.loader.VirtualWebappLoader (available in modern Tomcat 7, you can add own separate classpath to your .properties), and Parameter (accessed via FilterConfig.getServletContext().getInitParameter(name)) and Environment (accessed via new InitialContext().lookup("java:comp/env").lookup("name")):
<Context docBase="${basedir}/src/main/webapp"
reloadable="true">
<!-- http://tomcat.apache.org/tomcat-7.0-doc/config/context.html -->
<Resources className="org.apache.naming.resources.VirtualDirContext"
extraResourcePaths="/WEB-INF/classes=${basedir}/target/classes,/WEB-INF/lib=${basedir}/target/${project.build.finalName}/WEB-INF/lib"/>
<Loader className="org.apache.catalina.loader.VirtualWebappLoader"
virtualClasspath="${basedir}/target/classes;${basedir}/target/${project.build.finalName}/WEB-INF/lib"/>
<JarScanner scanAllDirectories="true"/>
<Parameter name="min" value="dev"/>
<Environment name="app.devel.ldap" value="USER" type="java.lang.String" override="true"/>
<Environment name="app.devel.permitAll" value="true" type="java.lang.String" override="true"/>
</Context>
If you use Spring and it's XML config:
<context:property-placeholder location="classpath:app.properties"/>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="oracle.jdbc.OracleDriver"/>
<property name="url" value="jdbc:oracle:thin:#${db.host}:${db.port}:${db.user}"/>
<property name="username" value="${db.user}"/>
<property name="password" value="${db.pass}"/>
</bean>
With Spring injecting above properties into bean fields are easy:
#Value("${db.user}") String defaultSchema;
instead of JNDI:
#Inject ApplicationContext context;
Enviroment env = context.getEnvironment();
String defaultSchema = env.getProperty("db.user");
Note also that EL allow this (default values and deep recursive substitution):
#Value('${db.user:testdb}') private String dbUserName;
<property name='username' value='${db.user.${env}}'/>

Externalize Tomcat configuration
NOTE With extending classpath to live directory you also allowed to externilize any other configs, like logging, auth, atc. I externilize logback.xmlin such way.
UPDATE Tomcat 8 change syntax for <Resources> and <Loader> elements, corresponding part now look like:
<Resources>
<PostResources className="org.apache.catalina.webresources.DirResourceSet"
webAppMount="/WEB-INF/classes" base="${basedir}/target/classes" />
<PostResources className="org.apache.catalina.webresources.DirResourceSet"
webAppMount="/WEB-INF/lib" base="${basedir}/target/${project.build.finalName}/WEB-INF/lib" />
</Resources>
You can try to place your configuration (properties file) in Apache Tomcat\lib in JAR file and remove it from the web application. When the Tomcat's class loader won't find your config in webapp it will try to find in "lib" directory. So you can externalize your configuration just moving the config to global lib dir (it's shared among other webapps).
I just added a setenv.bat or setenv.sh script in the bin folder of tomcat. Set the classpath variable like
set CLASSPATH=my-propery-folder

How to serve static web pages from a JSF application using Glassfish

I have a JSF 2.0 application running under Glassfish 3.1.1 and I need to serve static web pages that are physically located apart from my application root that is created when my WAR file is deployed. I've found various references (like this one and this one) to defining an alternate docroot using a tag such as
<property name="alternatedocroot_1" value="from=/myimages/* dir=/images"/>
added to sun-web.xml (which I would presume means glassfish-web.xml in Glassfish 3.1.1). I can't seem to get it to work, however. In my case, I think the problem is that glassfish-web.xml simply isn't defining enough context for the alternate docroot to have any meaning:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE glassfish-web-app PUBLIC "-//GlassFish.org//DTD GlassFish Application Server 3.1 Servlet 3.0//EN" "http://glassfish.org/dtds/glassfish-web-app_3_0-1.dtd">
<glassfish-web-app error-url="">
<class-loader delegate="true"/>
<jsp-config>
<property name="keepgenerated" value="true">
<description>Keep a copy of the generated servlet class' java code.</description>
</property>
</jsp-config>
<property name="alternatedocroot_1" value="from=/myimages/* dir=/images"/>
</glassfish-web-app>
The meat of my application definition seems to be much more in web.xml than glassfish-web.xml. Do I perhaps need to put something there instead to reference the alternate docroot?
This exact configuration requires a /images/myimages folder relative to the absolute root of the same disk as where the JVM of the webserver is running in. A file foo.png in that folder is then available by http://localhost:8080/contextname/myimages/foo.png.
A common confusion around this setting is that the from attribute is been interpreted as alone the context path in URL and not as an actual subfolder in the dir location. But this is thus not true.
If you're running Glassfish on a Windows environment then you need to specify the disk letter in the dir as well like so dir=C:/images.
