jwt-planner example

Added by Olaf van der Meer over 5 years ago

Hi,

I am discovering the jwt examples and cannot get the jwt-planner example running.

I get this error on the servers console when accessing the page in the browser:

In the README.md is written: In order to use it, you will need to setup a postgresql database.

I don't know how to do that. Can you provide me some more info how to do that and where should the database be located?

Thanks.

I already tried to add gson to the build.xml

it was:

  <target name="build">
    <ant dir="${jwt.dir}" target="all" inheritAll="false"/>

    <mkdir dir="${jwt-lib.dir}"/>
    <copy todir="${jwt-lib.dir}">
      <fileset dir="${jwt.dir}/dist" />
      <fileset dir="${jwt.dir}/lib" 
           includes="*.jar servlet-api/*.jar"/>
    </copy>

I copied gson/*jar from the jwt-charts/build.xml and add it like this:

  <target name="build">
    <ant dir="${jwt.dir}" target="all" inheritAll="false"/>

    <mkdir dir="${jwt-lib.dir}"/>
    <copy todir="${jwt-lib.dir}">
      <fileset dir="${jwt.dir}/dist" />
      <fileset dir="${jwt.dir}/lib" 
           includes="*.jar servlet-api/*.jar gson/*.jar"/>
    </copy>

RE: jwt-planner example - Added by Olaf van der Meer over 5 years ago

Hi,

I am getting a bit further now. I have copied the gson2-0.jar to the WEB-INF/lib manually and start the webserver using Run-Jetty-run.

Now I get a login screen. After trying to login an error occurs about unable to connect to the postgresql database. It is logical, beacause I did not settup it yet.

I have tried to install a postgresql database server to setup the database, but I can't on my Windows 10.

Is there another way to archeive this?

Thanks.

Hello,

Postgres does run on windows, and you can download it from here:
