GWT import external jar

[Qing]

Hi,

I'm now using gwt develop my web application. I create a gwt project
'OnlineBanker' in command line and import it into eclipse. The server
side code of OnlineBanker need to use the class in another java
project 'FinancialToolkit'. I export FinancialTookit as a jar file,
and import it into OnlineBanker by following away:
OnlineBanker->Properties->Java build path-> libraries -> Add external
Jars
and I add
<inherits name='FinancialFookit'/>into OnlineBanker.gwt.xml
I run it as OnlineBanker-shell, there's error
[ERROR] Unable to find 'FinancialTookit.gwt.xml' on your classpath;
could be a typo, or maybe you forgot to include a classpath entry for
source?

Any advice?

Hi,
It looks like you have to add to your jar file FinancialToolkit.gwt.xml.
This may help:

I added FinancialToolkit.gwt.xml into the jar. Doesn't work. do I need
to put this file to the folder of OnlineBanker as well?

Wait, if you only have a dependancy in your server-side code, why are
you trying to integrate the client code?

[Qing]

You mean I don't need to add <inherits name='FinancialFookit'/> to the
OnlineBanker.gwt.xml?

That is correct, if your external library is only used on the server
side (Hibernate, axis, etc) then there is no need to reference it in
your gwt.xml file.

However, if you do need to use it in your client code then it must
contain source (.java files) as well as have a gwt.xml file of its
own, AND be "translatable" (not something that your average java lib is)

Oh, i see. Thank you! It works.

Hi,

I included a example description for including external jars / Java
projects into GWT projects (client side) in this tutorial:
http://www.vogella.de/articles/GWT/article.html

Best regards, Lars

Hi I am also facing this same problem.
i have a jar file that contains .class files which I need for my project

How do I import them to my GWT project?

[Juan Pablo Gardella]

If you want to use this jar to be converted to javascript you need to add the sources no the .class. If you are using maven is easy:

<dependency>

<groupId>com.foo</groupId>

<artifactId>foo</artifactId>

<version>....</version>

                        <!-- Probably provided if you only use in the client side.-->  

</dependency>

<dependency>

<groupId>com.foo</groupId>

<artifactId>foo</artifactId>

<version>....</version>

                         <classifier>sources</classifier>

</dependency>

And in your GWT module add

<source path='com.foo' /> The package of the classes that you need.

BUT remember, not all classes can be converted to JS, check http://www.gwtproject.org/doc/latest/RefJreEmulation.html
