I tried to embed a Video in my GWT Project but I get the following error in my console when I open the panel containing the video:
No source code is available for type com.google.youtube.client.YouTubeEmbeddedPlayer; did you forget to inherit a required module?
My Build Path for the Project
And this is the example code
YouTubeEmbeddedPlayer youTubeEmbeddedPlayer = new YouTubeEmbeddedPlayer("hqXUKxJiDls");
youTubeEmbeddedPlayer.setWidth("427px");
youTubeEmbeddedPlayer.setHeight("320px");
absolutePanel.add(youTubeEmbeddedPlayer, 200, 30);
project.gwt.xml:
<inherits name="com.google.gdata.YouTubeAPI" />
<inherits name="com.google.youtube.Player" />
I followed the GettingStarted wiki entry but I don't know where to put the settings.xml (it's not explained).
Thank's in advance.
Try adding gwt-youtube-api-1.0.3-sources.jar to your classpath as a standard library instead of adding it as a source attachment for gwt-youtube-api-1.0.3.jar.

The problem - I am receiving the following message:
java.lang.ClassCastException: com.ibm.connector2.cics.ECIConnectionFactory incompatible with com.ibm.connector2.cics.ECIConnectionFactory
I am receiving it when trying to make the following statement:
eisDci = (ECIConnectionFactory)ctx.lookup(eisn);
The 'eisDci' has been defined previously:
private static ECIConnectionFactory eisDci = null;
And the 'eisn' is the String with the name of the conection like 'eis/DCIXxxxECI'
These connection is defined in the Server.xml:
<connectionFactory id="DCIXxxxECI" jndiName="eis/DCIXxxxECI">
<properties.cicseci ServerName="XXXX" TPNName="xx" connectionUrl="url" portNumber="2006"/>
</connectionFactory>
I understand that this is warning me that the cast is not possible. What I don't know is what I'm doing wrong. That must be comparing one version of the ECIConnectionFactory class with a different version of ECIConnectionFactory.
The server I'm working with is a Liberty, I'm going crazy, I can't figure out why Eclipse is comparing two different versions.
Similar problems I have searched for:
ClassCastException when casting to the same class
Waxwing's answer seems good, but I don't have access to make those changes, This connection is carried out by an external library.
First Thank you for your answer Ben Cox, in Liberty's server.xml (for LOCAL) I have declared the library:
<fileset caseSensitive="false" dir="C:\CICSECI"/>
And in the Liberty Runtime/Shared/resources I have cicseci.rar which I have declared in the server.xml as a resourceAdapter:
<resourceAdapter autoStart="true" id="cicseci" location="${shared.resource.dir}/cicseci.rar">
<classloader apiTypeVisibility="spec, ibm-api, api, third-party"/>
</resourceAdapter>
I have checked the rest of the libraries that I am importing into the project, and so far I have not seen that I have the repeated library.
I think the issue here has to do with classloading between your resource adapter and your application. This is something we more commonly see with DataSources but the results are the same.
The problem is that the same jar is being loaded by two different classloaders. One classloader for the resource adapter, and another classloader for your application. The solution is to use a commonLibraryRef
<library id=cicseci>
<file name="${shared.resource.dir}/cicseci.rar"/>
</library>
<resourceAdapter autoStart="true" id="cicseciRA">
<classloader commonLibraryRef="cicseci"/>
</resourceAdapter>
<connectionFactory id="DCIXxxxECI" jndiName="eis/DCIXxxxECI">
<properties.cicseci ServerName="XXXX" TPNName="xx" connectionUrl="url" portNumber="2006"/>
</connectionFactory>
<!-- Location of app that is trying to cast ECIConnectionFactory -->
<application location="${shared.resource.dir}/cicseci.rar">
<classloader commonLibraryRef="cicseci"/>
</application>
In this configuration, the cicseci.rar will only be loaded once.
ClassCastException can happen when the same class is loaded by two different class loaders, making what otherwise looks like the same class incompatible.
The mechanism that you should be using to avoid this involves configuring the application's class loader with a classProviderRef to the resourceAdapter, which is documented here. For example,
<application location=...>
<classloader classProviderRef="cicseci"/>
</application>

I import global libraries from different directories of my computer, in two of them the libraries were repeated with different versions, the obsolete versions were renamed, but it doesn't matter, the system recognized them as .jar and loaded them, producing the conflict.
I deleted the leftover libraries and it started working.
You have helped me a lot, and for that, Thank you.
I have a GWT application (FooGwtApp) and a library module (FooLib) used as a dependency in FooGwtApp. The package structure of FooLib looks like this:
packageFoo.ImportantClass
packageFoo.UnimportantClass
packageBar.OtherClass
I want ImportantClass (and only ImportantClass) to be compiled to JS by the GWT compiler. Moving ImportantClass to another package is not an option.
I created ImportantClass.gwt.xml within packageFoo with the following content:
<module>
<inherits name="com.google.gwt.user.User"/>
<source path="" includes="**/ImportantClass*"/>
</module>
Next I put an inherited reference to the ImportantClass module definition in FooGwtApp.gwt.xml (this seems to work: the IDE recognizes it, and is able to parse the reference to ImportantClass.gwt.xml).
Now If I put references to ImportantClass into FooGwtApp's client code, the GWT compiler fails, because it does not find ImportantClass on the source path:
No source code is available for type packageFoo.ImportantClass; did you forget to inherit a required module?
I likely messed up sommething in the source path / includes attribute in ImportantClass.gwt.xml - either defining the current package as root package with path="" is not a valid notation or something's wrong with the includes attribute. Or both. Or neither.
Can you give me a clue about where it all went wrong?
It turns out the problem was not in ImportantClass.gwt.xml, but in other Maven related stuff:
ImportantClass.gwt.xml should be placed under src/main/resources/packageFoo, not src/main/java/packageFoo, otherwise it won't be packaged into the binary jar.
GWT compiler compiles from Java source to Javascript source. This means we don't just need ImportantClass.class in FooLib.jar, but also its source. Best solution for this is to use maven-source-plugin in FooLib's pom.xml and also to import the FooLib dependency into FooGwtApp with sources classifier.
On the latter topic, see the following SO answers:
Maven: Distribute source code with with jar-with-dependencies
How to properly include Java sources in Maven?
After fixing the above problems, the source path declaration present in the question works.
In GWT , I have created two different projects,after compilationone is creating *.cache.html where else other one creating *.cache.js .Please assist why it is happening and where to config thess things.
In your *.gwt.xml file you can add a linker.
The standard linker is the xsiframe, which generates a *.cache.js file.
The std linker generates *.cache.html file.
Change it by editing the value of name in your *gwt.xml file:
<add-linker name="xsiframe" />
I'm building a custom odoo module that will be using several Javascript libraries.
I need to add references to those libraries (local references) but I don't know exactly where to place those libraries and how to refer to their location.
What I tried:
- I created the new module and placed the libraries inside the module directory but it didn't work.
- I also placed the libraries in the home directory of odoo.
As I understand, the problem would be solved if I could get the default directory of the webserver that odoo runs on.
If module is using js files, then you must put these files inside your module. And still if you cant reach these files from your module its your technical error and you have to fix it yourself, also note that odoo has its js libraries already
I found this page: how to add css and js files in Openerp 7 / Odoo module maybe can help you.
Below is the content.
Store files correctly:
CSS and JS files should be reside under 'static' directory in the module(the rest of subdirectory tree under 'static' is an optional convention):
static/src/css/your_file.css
static/src/js/your_file.js
Add files in manifest (v7.0) or in XML(v8.0)
Openerp v7.0 way is to add following entries in manifest (in openerp.py):
...
'css': ['static/src/css/your_file.css'],
'js': [static/src/js/your_file.js'],
...
Odoo v8.0 way is to add corresponding record in the XML:
Add XML to the manifest (openerp.py):
...
'data': [ 'your_file.xml'],
...
Then add following record in 'your_file.xml':
<data>
<template id="assets_backend" name="your_module_name assets" inherit_id="web.assets_backend">
<xpath expr="." position="inside">
<link rel='stylesheet' href="/your_module_name/static/src/css/your_file.css"/>
<script type="text/javascript" src="/your_module_name/static/src/js/your_file.js"></script>
</xpath>
</template>
....
....
</data>
Today I have read the document of Google Maps Android API v2, it said the project of android-sdk\extras\google\google_play_services\samples\maps can run,
but after I imported into eclipse and set the libraries of android-support-v4.jar and google-play-services.jar correctly, import com.example.mapdemo.R; in FeatureView.java (at line 24) can not find the file R.java.
almost all the java file in com.example.mapdemo need class "R", for example, the file BasicMapActivity.java need R in line 41 "setContentView(R.layout.basic_demo);" and line 71 mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();"
can someone tell me how to find the class "R"?
R
.java can not create automatically because the file multimap_demo.xml have some errors in
<br><br> <fragment
<br> android:id="#+id/map3"
<br> android:layout_width="match_parent"
<br> android:layout_height="match_parent"
<br> android:layout_weight="0.5"
<br> class="com.google.android.gms.maps.SupportMapFragment"
<br> map:cameraTargetLat="48.85"
<br> map:cameraTargetLng="2.35"
<br> map:cameraZoom="8"/>
<br><br>
eclipse said "cameraTargetLat", "cameraTargetLng" and "cameraZoom" can not recognized.
The error information:
Multiple annotations found at this line:
- error: No resource identifier found for attribute 'cameraTargetLat' in package 'com.example.mapdemo'
- error: No resource identifier found for attribute 'cameraTargetLng' in package 'com.example.mapdemo'
- error: No resource identifier found for attribute 'cameraZoom' in package 'com.example.mapdemo'
I do not know why.
If I change the code like this:
<br><br> <fragment
<br> android:id="#+id/map3"
<br> android:layout_width="match_parent"
<br> android:layout_height="match_parent"
<br> android:layout_weight="0.5"
<br> class="com.google.android.gms.maps.SupportMapFragment"/>
<br><br>
the errors disappeared, but i do not know if it can run.
Copy the maps_attr.xml file from the library project into your project's values folder.
You should also import google-play-services_lib project (/extras/google/google_play_services/libproject/google-play-services_lib) - after that cameraTargetLat and other ones are recognized and R.java is generated.
you should import /extras/google/google_play_services/libproject/google-play-services_lib as a library in your project.
Import an existing android project at /extras/google/google_play_services/libproject/google-play-services_lib, but remember COPYING IT TO WORKSPACE(important, maybe the path of its original place occurs error)
See your project's properties->Android settings and add library "google-play-services"
Remember to add android-support-v4.jar & google-play-services.jar to your External JARs
1, include both external jar to project
2, copy \extras\google\google_play_services\libproject\google-play-services_lib\res\values\maps_attrs.xml to project value folder
3, copy google-play-services_lib to workspace looks no necessary in my test.
Update:
java.lang.NoClassDefFoundError: com.google.android.gms.R$styleable in android
I solved it just adding the following meta-data to the AndroidManifest.xml
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
may be this answer can help someone.
this is due to a silly mistake, both the projects ie. Sample project of Map and Google play service project must reside on the same directory otherwise it will not referenced properly
you need do copy projects into workplace for both the projects or if you don't want to copy, so don't do it for both this is the glitch. if you do it properly then you will find this
you have to include xmlns:map="http://schemas.android.com/apk/res-auto" to your layout xml for using map element.
The R file is autogenerate by Eclipse, and you can find it in gen directory. Don't edit this file ever! In some case, you will find there more than one R file, for example when you add a library to your project, like google-play-services_lib. You always can refere to this file at code like this...
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(com.your.package.R.id.map)).getMap();
If you want to configure your map, is posible to make it by XML Attributes or Programmatically.
