Account.html and Reports.html Display Issue

[Guoqian Jiang]

Hi,

I downloaded gwtcx-0.7 and loaded into Eclipse as a maven project.
Following the instructions from previous threads in this list, I was
able to build the project and run it in development mode.

The main page "Serendipity.html" displays well but when I click the
New button or double click an account record in the context of
Accounts, it opens a new window and shows a warning "GWT module
serendipity may need to be (re)compiled" and a loading icon.

In the context of Reports, when I double click a report, it shows the
exception:

environment or system property, or as an applet parameter, or in an
application resource file: java.naming.factory.initial

Hi,

-> "GWT module serendipity may need to be (re)compiled"

I received the same error a few times as well. From the command line
try:

In the $(basedir) e.g. gwtcx:
mvn gwt:clean
mvn clean
mvn install

In project directory (e.g. gwtcx\gwtcx-samples\gwtcx-samples-smartgwt
\gwtcx-samples-smartgwt-serendipity):
mvn gwt:run

See also:

The reports will work, but only if you deploy the application to an
Application Server (e.g. Tomcat) that supports JNDI. The hosted mode
Application Server doesn't support JNDI.

Take a look at persistence.xml and you will notice that there are two
PUs defined. The hosted mode PU: name="HSQLDB-HOSTED-MODE-PU" and the
Tomcat PU: name="HSQLDB-TOMCAT7-CP-PU".

You can switch between PU's by changing the PU_NAME context param in
web.xml. Also when you deploy the application to Tomcat don't forget
to place a copy of the context.xml file in Tomcat's conf\Catalina
\localhost directory and rename it to serendipity.xml.

There are also some additional libraries (e.g hsqldb, tomcat-jdbc,
mail, etc.) required by the application that must be placed in
Tomcat's lib directory.

You can find them here:

Let me know how you go.

Cheers

Hi, Rob

Thanks for your prompt reply.

> In the $(basedir) e.g. gwtcx:
> mvn gwt:clean
> mvn clean
> mvn install
>
> In project directory (e.g. gwtcx\gwtcx-samples\gwtcx-samples-smartgwt

> mvn gwt:run

I followed your instructions above and it still was not working.

I will test the reports later on,

Thanks,
