Building step GWT-GX

[alejeune]

Hi Rob,

First of all, just want to thank you for the outstanding tutorial you
provided to the community. I was exploring the new capabilities of GWT
framework when I discovered your impressive work.

I've tested Serendipity-0.6.0 and now I'm willing to see more with gwt-
cx :-)

But I've been facing with an issue when I tried to build the project.
[INFO] GWTCX Core - Client has not been build successfully.

Is there something special to perform before the command line 'mvn
clean install' ?


Thanks for your help!

Hi,

->

dependency information available
[WARNING] The POM for com.allen_sauer.gwt.log:gwt.

log:jar:3.1.2 is
missing, no dependency information available

->

The lines above are the important ones.

Maven is telling you that it can't find these JARs (in a remote repository or) in your local repository.

This is because not everyone deploys their artifacts to a public repository. You can get around this problem by adding artifacts to your local Maven repository.

For example:

mvn install:install-file -DgroupId=com.allen_sauer.gwt.log -DartifactId=gwt.log -Dversion=3.1.3 -Dpackaging=jar -Dfile=gwt-log-3.1.3.jar -DgeneratePom=true

You should find copies of the required JARs in the gwtcx/lib directory.

Cheers
Rob

Thanks ! I'm still struggling with Maven issue but it is just a
question of time :-) .. I'm a rookie with this Maven framework ! I
understand that few jar files were not included in the Maven
dependencies so I tried to included them first manually with your
command line and then with Eclipse IDE but I'm having new issue.

'Project build error: 'dependencies.dependency.systemPath' for
net.sf.opencsv:opencsv:jar must be omitted. This field may only be
specified for a dependency with system scope.'

I keep some homework for this week-end :-(

Hi,

Just to clarify, if you follow the steps in this post:

-> http://uptick.com.au/content/getting-started-gwt-maven-and-eclipse

then it will help you get up and running with GWT, Maven and Eclipse.

A key step in setting up your environment is the installation of the gwt-maven-plugin as discussed in the post.

Once Eclipse is configured to work with Maven (via the gwt-maven-plugin) and GWT (via the Google Plugin for Eclipse) you should then only need to manually add any missing JARs (e.g. those not available via a public Maven repository) to your local repository.

-> and then with Eclipse IDE
Not sure what you mean? All configuration, etc is via the gwt-cx POMs (pom.xml). You can edit these in the Eclipse IDE, however, they should "just work".

As per this post:

-> http://uptick.com.au/content/gwt-cx-maven-multimodule-enterprise-project

-> I keep some homework for this week-end :-(
Ok, let me know how you go.

Cheers
Rob

Hi,

Well, not well !
As you proposed I added the library manually in order to get the
correct dependencies included in my respective pom.xml files but using
maven3 it stricly recommend not to use this workaround.

[WARNING] It is highly recommended to fix these problems because they
threaten the stability of your build.
[WARNING] For this reason, future Maven versions might no longer

The complete project gwtcx did not build properly so I built gwtcx-
core-client/gwtcx-core-server/gwtcx-core-shared successfully using
some modifications with my pom.xml files.

Then I tried to built the gwtcx-samples-serendipity project but it
didn't work (after I changed all libraries in my build path (GWT /
JRE) ) but I got this error message.

I did include the dependency 'gwtmultipage' so I do not understand
this issue.

HI,

-> As you proposed I added the library manually in order to get the

correct dependencies included in my respective pom.xml files but using
maven3 it stricly recommend not to use this workaround.

You added the JARs to your local Maven repository?

As I mentioned there are quite a few JARs that aren't yet available via a public Maven repository (see below, sample commands to add these to your local repository).

-> [WARNING] 'dependencies.dependency.systemPath' for com.allen_sauer.gwt.log:gwt.log:jar should use a variable instead of ahard-coded path C:\eclipse\Workspace\gwtcx\libs\gwt-log-3.1.2.jar @line 342, column 19

How exactly did you add the gwt-log JAR to your local Maven repository? For example, did you execute the mvn install:install-file goal from the lib directory?

You can install gwt-multipage (from the lib directory) as follows:

mvn install:install-file -DgroupId=org.gwt-multipage -DartifactId=gwt-multipage -Dversion=1.0.0 -Dpackaging=jar -Dfile=gwt-multipage.jar -DgeneratePom=true

->

mvn install:install-file -DgroupId=org.apache.tomcat -DartifactId=com.springsource.org.apache.tomcat.jdbc -Dversion=1.1.0.1 -Dpackaging=jar -Dfile=tomcat-jdbc.jar -DgeneratePom=true

mvn install:install-file -DgroupId=com.allen_sauer.gwt.log -DartifactId=gwt.log -Dversion=3.1.2 -Dpackaging=jar -Dfile=gwt-log-3.1.2.jar -DgeneratePom=true

    mvn install:install-file -DgroupId=org.hsqldb -DartifactId=hsqldb -Dversion=2.0.1-rc1 -Dpackaging=jar -Dfile=hsqldb.jar -DgeneratePom=true
   
    mvn install:install-file -DgroupId=commons-fileupload -DartifactId=commons-fileupload -Dversion=1.2.1 -Dpackaging=jar -Dfile=commons-fileupload-1.2.1.jar -DgeneratePom=true

mvn install:install-file -DgroupId=net.sf.opencsv -DartifactId=opencsv -Dversion=2.2 -Dpackaging=jar -Dfile=opencsv-2.2.jar -DgeneratePom=true

   mvn install:install-file -DgroupId=net.sf.jasperreports -DartifactId=jasperreports -Dversion=4.0.0 -Dpackaging=jar -Dfile=jasperreports-4.0.0.jar -DgeneratePom=true

    mvn install:install-file -DgroupId=org.slf4j -DartifactId=slf4j-log4j12 -Dversion=1.6.1 -Dpackaging=jar -Dfile=slf4j-log4j12-1.6.1.jar -DgeneratePom=true
   
    mvn install:install-file -DgroupId=org.slf4j -DartifactId=slf4j-api -Dversion=1.6.1 -Dpackaging=jar -Dfile=slf4j-api-1.6.1.jar -DgeneratePom=true

mvn install:install-file -DgroupId=com.smartgwt -DartifactId=smartgwt -Dversion=2.4 -Dpackaging=jar -Dfile=smartgwt.jar -DgeneratePom=true

mvn install:install-file -DgroupId=org.gwt-multipage -DartifactId=gwt-multipage -Dversion=1.0.0 -Dpackaging=jar -Dfile=gwt-multipage.jar -DgeneratePom=true

Hi,

I defined the dependency in the pom.xml file as follow for couple of
dependencies. Some of them were used

<!-- GWT-Log dependencies -->
<dependency>
<groupId>com.allen_sauer.gwt.log</groupId>
<artifactId>gwt.log</artifactId>
<version>3.1.2</version>
<type>jar</type>
<scope>system</scope>
<systemPath>C:\eclipse\Workspace\gwtcx\libs\gwt-log-3.1.2.jar</
systemPath>
</dependency>

I rebuild the project with all command lines you suggested and it did
build all project except the
com.springsource.org.apache.tomcat.jdbc-1.1.0.1.jar librairy.

Because it is not installed in the gwtcx\lib folder (jaspersoft is
missing as well but I guess it is available on the maven repository),
I copied the com.springsource.org.apache.tomcat.jdbc-1.1.0.1.jar from
com.springsource.org.apache.tomcat.jdbc-1.0.9.3.jar and it built
successfully.

Hi,

You don't need to modify any of the gwt-cx POMs. 

e.g. gwt-log is already declared as a dependency (see gwt/gwt-core/pom.xml):

->

      <!-- GWT-Log dependencies -->
      <dependency>
        <groupId>com.allen_sauer.gwt.log</groupId>
        <artifactId>gwt.log</artifactId>

        <version>${gwt.log.version}</version>
      </dependency>

->

and the version in declared in gwt/pom.xml:

->

    <gwt.log.version>3.1.2</gwt.log.version>

->

You just need to make the dependencies available via your local Maven repository.

The Tomcat 7 CP is in "apache-tomcat-jdbc-1.1.0.1-bin.zip" in the /lib folder. It also depends on "bonecp-0.7.1.RELEASE.jar" - take a look at the persistence.xml file in /META-INF.

The dependencies are declared in gwt/gwtcs-samples/pom.xml:

->

    <!-- HSQLDB dependencies -->
    <dependency>
      <groupId>org.hsqldb</groupId>
      <artifactId>hsqldb</artifactId>
      <version>${hsqldb.version}</version>
      <scope>provided</scope>
    </dependency>
    <!-- SpringSource / Apache Tomcat 7 JDBC Pool Connection Pool Manager dependencies -->
    <dependency>
      <groupId>org.apache.tomcat</groupId>
      <artifactId>com.springsource.org.apache.tomcat.jdbc</artifactId>
      <version>${com.springsource.org.apache.tomcat.jdbc.version}</version>
      <scope>provided</scope>       
    </dependency>   

->

Cheers
Rob

Hi,

Sorry, I meant the Tomcat 7 CP also depends on "guava-r08.jar".

Cheers
Rob

Hi Rob,

Great ... Now it did build successfully on my environnement :-)
Thanks a lot !

I did a mistake when I installed
com.springsource.org.apache.tomcat.jdbc 1.1.0.1 artifact.

Instead of the command line you gave me, mvn install:install-file -
DgroupId=org.apache.tomcat -
DartifactId=com.springsource.org.apache.tomcat.jdbc -Dversion=1.1.0.1 -
Dpackaging=jar -Dfile=tomcat-jdbc.jar -DgeneratePom=true
I used the jar available in the gwtcx/libs folder
com.springsource.org.apache.tomcat.jdbc-1.0.9.3.jar

Mea Culpa !

I could have save a lot of time reading carefully that the file you
install for the dependency is 'tomcat-jdbc.jar' in the zip file.

I'm good with the build step !!

Thanks a lot ..

Hi,

I think I may have accidentially mislead you as well :-)

After checking the doco re Tomcat 7's CP:

-> http://people.apache.org/~fhanik/jdbc-pool/jdbc-pool.html

These are the correct libs:

- tomcat-dbcp.jar
- tomcat-juli.jar

There is a interesting discussion re connection pools here:

-> http://stackoverflow.com/questions/520585/connection-pooling-options-with-jdbc-dbcp-vs-c3p0

and

-> http://www.tomcatexpert.com/blog/2010/03/12/explaining-jdbc-pool-high-concurrency-alternative-connection-pooling-module

The only problem I experienced was that after running the application,
I couldn't login because no datasource ('HSQLDB....') could be found.
I believe I will solve the issue soon...but perhaps other people had
already the same problem...

An other question about documentation : is there a document giving an
overview about application/used tools/etc., perhaps also describing
the 'architecture' of the application ?
I'm asking because I'm new on GWT. I know well back-end parts of
applications but that's the first time I start with the front-end
based on GWT.
You created DTO objects to map from business objects to View Objects.
There are also CommandHandlers, used apt ...Are these things part of
the 'standard/common' GWT development ?

Finally, I would like to congratulate you and the development team
because it's not easy to find in the internet a tutorial for a good
enterprise application (multimudule, separation of front- and back-end
concerns)

(Perhaps my comment should have been posted in an other thread !?
Sorry ;-)

Esteban.

Hi Rob,

thank you for the interesting tutorial.
I was able to start the application but I couldn't pass the login-
dialog.
Because there is a problem with the datasource (couldn't find the find
datasource 'HSQLDB....')
Is that a common issue, and what's the solution for that ?
I believe I will solve it...but perhaps other people had already the

same problem...

An other question about documentation : is there a document giving an
overview about application/used tools/etc., perhaps also describing
the 'architecture' of the application ?
I'm asking because I'm new on GWT. I know well back-end parts of
applications but that's the first time I start with the front-end

Hi Esteban,

Thanks for your feedback :-)

You just need to point the sample application (Serendipity) to the data source.

Take a look at this post:

 -> http://groups.google.com/group/gwt-cx/browse_thread/thread/ed71fd234b4601f5

And let me know if you run into any issues.

I am working on the documentation. In the mean time you can post questions here.

Cheers
Rob
