A blank page appears after deploying sample-web

[Suhothayan Sriskandarajah]

I populated the database with the given .sql file and I too was able to deploy the sample-web successfully with out error.
But when I go to the page http://localhost:8080/persistence4J-sample-web/
I'm getting a blank page.

Why is this, is there any prerequisites I'm missing ?

After deploying and when you go to http://localhost:8080/persistence4J-sample-web/ check the logs is there any error message?.If there is error message please post the error message here.Most probable reason is that the credentials of database not right.before building the sample application change the credentials as per you database installation in persistence.properties of persistence4J-sample-web.

To use the right credentials go to

persistence4J-sample-web/war/

WEB-INF/persistence.properites and search for following lines

persistence.dbms.mysql.username=mysql
persistence.dbms.mysql.password=mysql

Now here you change username and password of you mysql installation.


Please try these steps and tell me if it working.

Yes I did all of these, and there was no error in the logs too.
but, when I inspect the lorded HTML(blank page) I found that it is trying to load  sample/sample.nocache.js file which is not there.

How can I over come this issue?

Most probable reason is that its not building properly.
can you see following lines while building

another option is to run the sample application from the eclipse.To
run from eclipse you have to install the google gwt plugin [1]

[1]. http://code.google.com/eclipse/docs/download.html

I think you are using quite old version of maven.This sample
Application is tested on maven 2.2.1. You should upgrade maven and if
you are using ubuntu 10.04 its in the repository.

yes, thanks for the tips
it's a maven issue, after changing to maven 2.2.1, I was able to build it and run it properly
