I would like to use the org.apache.commons.validator.GenericValidator class in a view class of my GWT web app. I have read that I have to implicitely tell that I intend to use this external library. I thought adding the next line into my App.gwt.xml would work.
<inherits name='org.apache.commons.validator.GenericValidator'/>
I get the next error:
Loading inherited module 'org.apache.commons.validator.GenericValidator'
[ERROR] Unable to find 'org/apache/commons/validator/GenericValidator.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?

I have commons.validator-1.3.1.jar in war/WEB-INF/lib
I am using eclipse with Google Plugin.
Anyone knows how it works?
The syntax <inherits name='package.SomeModule'/> is only for special GWT modules, built to be used with GWT, not generics Java libraries (docs). A quick test to see if a jar/library is built to be used with GWT is to see if it includes a module file. If you look at the error you posted the top line reads:
Loading inherited module 'org.apache.commons.validator.GenericValidator'
[ERROR] Unable to find 'org/apache/commons/validator/GenericValidator.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?
You can see that commons.validator is missing the required module file. You can still use this library on the server side (no restrictions there). For client side, chances are GWT doesn't emulate the required parts of Java - for more information see the docs.
Alternatively you can add the GWT module XML file to your project. I've had to do this in the past.
This is not "ideal", but it saves you from having to repackage the jars.
In this case, you could create a file named "Commons.gwt.xml" and put it in a /org/apache/commons directory in your local source path. The file would contain:
<module>
<source path="validator"/>
</module>
Then, you would just need to add the line <inherits name="org.apache.commons.Common"> to your application.
What you would need to do if this was your library would be to add in a XXX.gwt.xml file for each package that you want GWT to be able to compile to. This is how you would add in a shared jar for instance into a GWT frontend of a multi-tiered (and multi-server) app. You can take any of the GWT libraries and unzip their jars to see what I mean, there will be a file called XXX.gwt.xml one level above all packages that GWT needs to be able to use to compile.
In the past I have taken and re-packaged some of these open source libraries, which you could do here. This is problematic since then you really need to source control your version of the library, and would have to manually merge any new changes (or just redo the XXX.gwt.xml file entries and repackage).
So this is not the best case scenario (but sometimes you're looking for miss right now and not miss right), is there no way around this just using core GWT and Java? I know the pre-fab libraries are great, but is the dependency with the extra work worth the time savings in you particular case?
I hope that helps.

I am trying to install a plug-in to eclipse from an update site. But, somehow that is not working (might be tool has ended support from update site). Although, i have found source code of plug-in from github(but it is not compiled version). I could download it as zip file. But, I am facing issues related to installation. It contains lot of plugin.xml files in different folders. But, i am not sure, which one to use.
This is the url for plug-in source code.
please help with the steps to install eclipse plugin from source code.
#ChandrayyaGK : I have followed steps mentioned in your answer.I am facing following error.

You have to have github account to clone or download sources from github. Create your github account then go to this project then click on clone or download button then download the sources as zip file.
You have to build these sources to get eclipse plugin, so unzip the content.
Location of graphiti p2 repo changed now so open the file
/Activiti-Designer-master/org.activiti.designer.parent/pom.xml
and change line from
<graphiti-site>http://download.eclipse.org/graphiti/updates/0.11.4</graphiti-site>
to
<graphiti-site> http://archive.eclipse.org/graphiti/updates/0.11.4</graphiti-site>
Go to Activiti-Designer-master/org.activiti.designer.parent folder in command prompt then run the command mvn clean install(Install maven if not installed).
I tried this and able to build this plugin successfully on my machine. By default it builds plugin for eclipse luna platform. So open eclipse luna and add /Activiti-Designer-master/org.activiti.designer.updatesite/target/repository folder as your update site then click install. Refer this for installing new software/plugin in luna.
About getting graphiti p2 repo.
Only solution worked for me, is to take graphiti site from a local folder.
Like it is described here Activiti Designer - build failures
download ZIP file: http://archive.eclipse.org/graphiti/archives/0.11.4/org.eclipse.graphiti.site_0.11.4.201507011432.zip
unzip it and set org.activiti.designer.parent/pom.xml <graphiti-site> value accordingly to point unzipped folder
in my case it was windows dir so e.g.:
<graphiti-site>file:///C:/temp/org.eclipse.graphiti.site_0.11.4.201507011432</graphiti-site>
after that i was able to build designer successfully.
ps. Sorry guys, I don't have enough reputation points to put this as a comment to a previous answer where it seems to be more obvious place.
We are trying to create a functional example with Hibernate, JBoss7, Beans and Servlets using Eclipse as an IDE.
In other example project we were able to make functional Servlets, and we were able to use Hibernate.
We created two eclipse projects:
A Dynamic web project, an Enterprise Java Beans (EJB) project and a EAR project connecting both.
Running a simple test.java file which uses hibernate (and worked on other projects), we the get errors:

The problem now seems to be around the jars that we included using project Properties > Java Build Path > Add External Jars for the EJB project:
We added the slf4j-jdk14-1.7.5.jar and hibernate jars but the exception log appears to be indicating that we are still missing some jar.
If we remove the jars from the Java Build Path, the exception log is the same. So we think that the jars are not being deployed correctly, or some extra configuration is required... even thought they appear in the /lib folder inside the EJB project deployment folder.
Is there any procedure we are missing, or any probable causes to investigate? I'll add more info if needed. Thanks.
When using JBoss7 not all Jars are available to the application by default (for example slf4j). You have to specify which modules should be included in the classpath of the application by putting this information into a file in your application.
I always do it by adding jboss-deployment-structure.xml into my application (the EAR in your case).
Here's how https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7.
(The name of the module in your case would be org.slf4j)
Throwing slf4j jar in the libs folder can create a conflict with the slf4j module already included in JB7 by default... you have to add the dependency to your jboss-deployment-structure.xml
But if your hibernate jars are in the libs folder, they could fail resolve the dependency as well too... the way to go in JB7 would be to make a module for Hibernate too, the Nightie builds of JB7 already include an hibernate module, you could just copy the module from there, then add it to your jboss-deployment-structure.xml
I have a maven project with spring. And we also have alot of JUnit test classes. We are using Eclipse. Every now and then - quite often actually - eclipse shows some (not all) of the test classes as red... Claiming it cant find imports. Looking at Eclipse error log, I can see alot of these error messages (but for different test-classes ofc).
What is happening? My collegue who works with the same project does not get this error. We are using Eclipse Juno SR2.

The problem could be in the jars dependencies (especially if you're using mocks). You need to perform two steps to figure out what the problem is:
1.Run unit tests using maven (in case it works you can go to step2);
2. Look into jars order in the Eclipse (projects setting-> java build path-> order and settings).
In case you said that it works for your colleague you need to compare order of your jars with jar's order of you colleague
The error I'm getting is well discussed here, but I still can't seem to get a grip on what I'm doing wrong.
I'm trying to run a simple code with java3d. I added the jard to the Maven Dependencies and they are showing up. No errors are displayed and everything seems fine.
But when I'm trying to compile the code, all of a sudden the message

appears.
Apparently I'm just missing some trivial error. Since the question has been asked so many times, the answer should be somewhere.
I added the Jars via the pom.xml with
<dependency>
<groupId>java3d</groupId>
<artifactId>j3d-core-utils</artifactId>
<version>1.3.1</version>
</dependency>
You are missing a native library (i.e. a dll or so file).
I do not know how to correctly reference that from maven (apparently there is something like a NAR that you can built, but I have not researched that yet).
A quick solution for eclipse is to add the dll as a native dependency to your Maven Dependencies library in eclipse:
In the "Libraries" tab in "Java Build Path" in the project properties, expand "Maven Dependencies" and edit "Native library location" to point to the directory containing your native library.
If the above solution is not working try to manually install maven and j3d, or reinstall it.
a missing file is sometimes a really bad sign, because sometimes if 1 file is missing maybe you haven't installed propertly and other files will be missing later on so i suggest you reinstalling.
I have a problem running my gwt2.4rc1 application in a tomcat. The problem occurs when I try to make a requestfactory call. Then I get the exception at the bottom.
When I run GWT in development mode everything works fine. The gwt-dev. jar is in the lib folder of my webapp. I am using maven for dependency management. Could there be a problem with my configuration? I already had the error with gwt2.4 beta. If there are any other information required to solve this problem I am glad to provide them.
Regards,
Arne

There's a fix for this on its way over from RC to trunk. In the mean time, remove gwt-servlet from your dependencies and use requestfactory-servlet.jar instead.
I've always understood gwt-dev.jar to be the compiler and other development tools. If you believe that, there should be no dependency on it from your own code, and there is no reason for it to be in the WEB-INF/lib folder of your war file.
I see from this question that at least one other contributer to SO feels the same way, but the belief doesn't appear to be universal.
I'll update this answer if I can find anything one way or the other in the GWT docs.
Update:
The closest thing I could find was Organize Projects which shows gwt-dev as a referenced library not present in WEB-INF/lib. I can't find anything official that says either that you can or can't deploy it to your web server. In an old book GWT In Action (Hanson, 2007), page 551 says
You should never deploy the gwt-user.jar and gwt-dev.jar files to your server,
because they will interfere with your server; these JAR files contain their own
Tomcat server code, which is used when you're testing in hosted mode.
This is clearly out of date, since hosted mode isn't called that anymore and uses an embedded Jetty server rather than Tomcat, but that's the basis for my belief.
Ok I made it working :)
I used the gwt version compiled from here:
http://code.google.com/p/google-web-toolkit/source/browse/#svn%2Freleases%2F2.4
I did put gwt-servlet.jar and requestfactory-servlet.jar as dependencies in my project. The problem in the other thread occured because I used my own group-id for the compiled jars, so these were not used by gin and the gwt-maven-plugin. No everything works fine :)
Thanks for the help though!!
