Smart GWT Pro/EE Project Setup & Deployment

Creating a new project from scratch

If you are starting a new project from scratch, we recommend starting with one of the sample projects included with SmartGWT EE under the "samples" directory. Use the project that most closely matches your integration strategy and follow the instructions in the "readme" file within the sample directory.

Adding SmartGWT EE to an existing project

Important: If you have created a project using the GWT Plugin for Eclipse or a similar tool, first get rid of unused resources typically included in such "starter projects":

Now add SmartGWT EE: all of these steps are required. Do not skip steps or omit resources you think you may not need. Get a working project first, then think about trimming resources, as needed, once you understand the system.

In the steps below, copying from eg "war/WEB-INF/..." means copying from the "war" subdirectory of whichever sample project is closest to your desired integration strategy.

  1. add all jars from the SmartGWT Pro/EE distribution (under smartgwtee-version/lib) to your CLASSPATH. You can copy the '.classpath' file from the appropriate sample project for a working set of includes (it's in the same directory as the war/ folder). There are both client- and server-side jars, both kinds go in the classpath. For server-side .jars, dependencies are documented here.
  2. update your modulename.gwt.xml file with these imports:
         <inherits name="com.smartgwtee.SmartGwtEE"/>
         <inherits name="com.smartgwtee.tools.Tools"/>
         
    NOTE: if you were previously using SmartGWT LGPL, remove the <inherit> of 'com.smartgwt.SmartGWT' and ensure the <inherit> of 'com.smartgwt.tools.SmartGwtTools' appears before the imports above. Also ensure that all SmartGWT-related inherits appear *before* your <entry-point> declaration.
  3. if you are using Optional Modules such as Analytics or RealTimeMessaging, see LoadingOptionalModules for additional inherits
  4. Copy log4j.isc.config.xml across to the "src" dir of your project (it's placed in the "src" dir as a means of getting it into the CLASSPATH). This file is either in the "src/" dir of a given sample project or in war/WEB-INF/classes. This enables default log4 categories for server-side logs appropriate for development.
  5. Copy server.properties across to the "src" dir of your project. This file is either in the "src/" dir of a given sample project or in war/WEB-INF/classes. This contains miscellaneous server settings - see the file itself for documentation.
  6. If you plan to use JPA, copy src/META-INF/persistence.xml into your src/META-INF directory. This file will be copied into war/WEB-INF/classes/META-INF directory during build process. Make sure you specify your entity classes in persistence.xml. If you change persistence unit name you have to update "jpa.persistenceUnitName" property in server.properties file. More information on JPA configuration can be found in JpaIntegration.
  7. merge web.xml, starting with the web.xml from the sample project that is closest to your target application (under war/WEB-INF in the sample project). The list of servlets and what they do is documented here. See the server-side JavaDoc for further details on servlet APIs and override points.
  8. Copy war/WEB-INF/iscTaglib.xml to your war/WEB-INF/iscTaglib.xml. This is required for JSP tags to work and used by tools such as Visual Builder. Be sure you have also copied the web.xml section that enables the taglib (<jsp-config> element)
  9. (SmartGWT Power or Enterprise only) If using the BatchUpload functionality, copy war/ds/batchUpload.ds.xml from the Showcase sample project to the shared.datasources directory you configured in server.properties.

    Troubleshooting

    . For more in-depth troubleshooting steps, see +link{http://forums.smartclient.com/showthread.php?t=8159#aDSLoad,this FAQ answer}.
    Problem Possible Causes Solution
    ClassNotFound or other Java Exceptions in the server log. Missing JAR files Verify every .jar from the smartgwtee-version/lib directory has been added to your CLASSPATH. Although you might later be able to remove some .jars, for initial installation testing, copy every .jar
    Client-side error about attempting to use "iscServer" request without server installed Wrong imports in moduleName.gwt.xml See correct imports above, note remove com.smartgwt.SmartGWT import and be sure imports are in the correct order
    Client-side error about "$debox is not defined" Wrong order of imports in moduleName.gwt.xml Make sure all SmartGWT-related imports appear before <entry-point> in your .gwt.xml file
    Missing images or failure to load page Didn't set isomorphicDir in .html bootstrap file See step above for setting isomorphicDir
    Server error: "adminConsole" app not found when launching tools such as Visual Builder Bad filesystem paths configured in server.properties Correct paths in server.properties. NOTE the samples include the GWT module name in some settings, search and replace this value with your GWT module name
    Server error: Can't find DataSource with ID yourDataSourceID Bad filesystem paths in server.properties or bad DataSource .ds.xml file Correct paths in server.properties - search for "project.datasources". Also check that the DataSource ID you are using matches the "ID" attribute in the .ds.xml file (NOTE: ID attribute is uppercase "ID" not "id") and that the file is named dataSourceId.ds.xml. DataSource IDs are case sensitive, including the file name
    Server error: taglib not defined Missing iscTaglib.xml or iscTaglib.xml not referenced in web.xml See step above about iscTaglib.xml and web.xml entry

    For further troubleshooting steps, see the SmartGWT FAQ and, if still stuck, try posting in the Forums. NOTE: gather all the information indicated in the FAQ before posting.

    NOTE: It is possible to create a server-only SmartGWT EE project that will run standalone (ie, not inside a servlet container or application server). Please see Standalone DataSource Usage for details.
