T5 Creating a Library of Custom Components
Hi,
I'm trying to create a T5 library using Eclipse, but... :(
Here are my steps and codes.
- New Java Project: t5lib
- Compiler compliance level is set to 5
src
src/pub/t5lib
src/pub/t5lib/LibraryModule.java
src/pub/t5lib/components
src/pub/t5lib/components/MyComponent.java (don't have a template)
src/MANIFEST.MF
- In Eclipse: Project Properties: Java Build Path: Libraries: Add JAR's:
tapestry-core-5.0.11.jar
tapestry-ioc-5.0.11.jar
LibraryModule.java:
---------------------------
package pub.t5lib;
import org.apache.tapestry.ioc.Configuration;
import org.apache.tapestry.services.LibraryMapping;
public class LibraryModule {
public static void contributeComponentClassResolver(
Configuration<LibraryMapping> configuration) {
configuration.add(new LibraryMapping("t5lib", "pub.t5lib"));
}
}
MyComponent.java: (just a simple output component)
----------------------------
package pub.t5lib.components;
import org.apache.tapestry.ComponentResources;
import org.apache.tapestry.MarkupWriter;
import org.apache.tapestry.annotations.Parameter;
import org.apache.tapestry.ioc.annotations.Inject;
import org.apache.tapestry.ioc.internal.util.InternalUtils;
public class MyComponent {
@Parameter(required = true)
private Object _value;
@Parameter("componentResources.elementName")
private String _elementName;
@Inject
private ComponentResources _resources;
boolean beginRender(MarkupWriter writer) throws Exception {
formatted = ((Format) _format).format(_value);
if (InternalUtils.isNonBlank(formatted)) {
if (_elementName != null) {
writer.element(_elementName);
_resources.renderInformalParameters(writer);
}
writer.write(formatted);
if (_elementName != null)
writer.end();
}
return false;
}
}
MANIFEST.MF:
----------------------
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.5
Created-By: 1.6.0_02-b06 (Sun Microsystems Inc.)
Tapestry-Module-Classes: pub.t5lib.LibraryModule
PS: last line of manifest ends with a carriage return.
- in Eclipse: Project Explorer: Export...
- JAR file
- None resources select on t5lib root, just src sub-folder, checked "Export
generated class...", JAR file: C:\t5lib-0.0.1.jar , checked "Compress..."
- only checked "Build project..."
- Use existing manifest from workspace, /t5lib/MANIFEST.MF <Finish>
- just put the library file (t5lib-0.0.1.jar) into the WEB-INF/lib subfolder
of another project (a new T5.0.11 project, just created with maven, with
only Index.tml)
- Trying to use a component in Index.tml, like this:
<t:t5lib.MyComponent t:value="currentTime" />
or like this:
<span t:type="t5lib/MyComponent" t:value="currentTime" />
ERROR
Unable to resolve 't5lib/MyComponent' to a component class name. Available
component types: ActionLink, Any, BeanDisplay, BeanEditForm, BeanEditor,
Checkbox, DateField, Delegate, Errors, EventLink, ExceptionDisplay, Form,
FormFragment, FormInjector, Grid, GridCell, GridColumns, GridPager,
GridRows, If, Label, Loop, Output, OutputRaw, PageLink, Palette,
PasswordField, PropertyDisplay, PropertyEditor, Radio, RadioGroup,
RenderObject, Select, Submit, SubmitNotifier, TextArea, TextField,
TextOutput, Unless, Zone.

I had a similar problem. Do you use Maven2 for dependency handling? The
Maven Eclipse plugin will use the Eclipse project (containing the
component) instead of the jar file.
If you close the Eclipse project containing the component the plugin is
forced to use the jar file (that contains the correct MANIFEST.MF).

Hi Thiago,
- MANIFEST.MF was extracted from JAR and checked, file is ok
- Try putting JAR in project build path.
same error :(

Hi!
Check your JAR's MANIFEST.MF. If it is OK, try putting your JAR in the
classpath through Eclipse project settings instead of just dropping
your JAR in WEB-INF/lib.

Hi Thiago,
You are right, LibraryModule was not loaded.
generated JAR:
META-INF
META-INF/MANIFEST.MF
pub
pub/t5lib
pub/t5lib/LibraryModule.class
pub/t5lib/components
pub/t5lib/components/MyComponent.class
any idea?
Thanks,
Marcus
Re: T5 Creating a Library of Custom Components

It looks like your LibraryModule was not loaded. To ensure it is, put
a System.out.println("Module loaded!") in your
contributeComponentClassResolver() method. Also check the generated
JAR to ensure everything is in the proper place.
