Service Builder (problem: PORTLET DISAPPEARS)

[portal-rb.ru i, modificado 12 Anos atrás.]

Liferay: 6.1 b4

1. Run Tomcat.
2. Create MVC portlet with superclass javax.portlet.GenericPortlet .
3. Add the portlet to the server, which appears in the dropdownlist.
4. Create a service over the portlet.
5. Edit the file service.xml (change <!DOCTYPE service-builder PUBLIC "-//Liferay//DTD Service Builder 6.0.0//EN" "http://www.liferay.com/dtd/liferay-service-builder_6_0_0.dtd">
to <!DOCTYPE service-builder PUBLIC "-//Liferay//DTD Service Builder 6.1.0//EN" "http://www.liferay.com/dtd/liferay-service-builder_6_1_0.dtd">).
6. Press "Build" button (either from Eclipse or from command line (cmd) "ant service-build").
7. A table should be created in a database.
8. The portlet disappers from the LifeRay list. Redeploy does not help, there are a lot of errors.

Could you help me to solve this problem, please?

[Raja Nagendra Kumar, modificado 12 Anos atrás.]

Check your portlets init() method.. keep it empty and try... (no exception should be thrown during deploy or while adding this portlet to a new page)

Some thing is wrong in your init() method.

Can you try to build the services from command prompt & deploy. If you can please add your source code

As a service?

[Nagendra Kumar Busam, modificado 12 Anos atrás.]

Initial Service generation part you can do it from Liferay IDE. Once you generate sample service.xml using Liferay IDE. Try to build that service from command prompt

Try below commands from command prompt
> ant build-service
> ant clean deploy

Did you try to deploy it properly, as it seems you are getting error while creating the portlet itself.

Nagendra Kumar Busam:

I have the same error as the first post of the thread.

I only used Liferay IDE to create service and deploy.

Does that works for you in latest 6.1 sources?

[ildar i, modificado 12 Anos atrás.]

It appears that an error is initially in the software.
I do not know how to create the "Service Build" via the command line.


E:\b41\sdk\portlets>create Newsp "qwertt"
E:\b41\sdk\portlets>cd Newsp-portlet
E:\b41\sdk\portlets\Newsp-portlet>ant build-service
(errors)
E:\b41\sdk\portlets\Newsp-portlet>ant clean deploy
E:\b41\sdk\portlets\Newsp-portlet>

When shell I create "service.xml" file ?




Regarding my first post, is it possible to find out the problem by analysing logs?

Hi ildar,

When I am trying to execute ant build-service using command prompt, in my Liferay 6.1 b4 , me to getting exactly the same error.
Have you managed to find any resolution to this issue ?

Forget b4. Download GA and final SDK and re-test. If not, should be a config/XML problem.

Ext plugins are not to add a service to liferay. They are to modify what is already present in liferay.

[Krzysztof Gołębiowski, modificado 12 Anos atrás.]

Yeah, but I need to have this service available through all my plugins. As far as I remember, it is hard to achieve that with hooks or portlets (I have to copy service jar's to tomcat/lib/ext manually).

Totally untrue.

All you need to do is go to the dependent portlet (the one that will be calling the service) and add the project containing the service as a required deployment context (in the liferay-plugin-package.properties file).

No more do you need to copy jars to tomcat/lib/ext (was always a bad practice, required reboots, etc.) and also allows them to deprecate adding services to EXT (it's planned, but I don't know when they will be rolling that out).

So stick with the service in another plugin (i.e. a portlet plugin) and add the required dependency context to the service users.

[Krzysztof Gołębiowski, modificado 12 Anos atrás.]

Dawid, thanks for your answer, I didn't know that I tried to create the service within hook plugin, but there is one problem. I am referencing few Liferay entities:

...
<column name="memberEntry" type="Collection" entity="com.liferay.portal.User"
mapping-key="userId" />
...
<reference entity="User" package-path="com.liferay.portal" />
...

Everything looks fine service builder builds the service, war file is generated, but during deployment i get the following exception:

...
Caused by: java.lang.Error: Unresolved compilation problems:
com.liferay.portal.model.impl.UserModelImpl cannot be resolved to a variable
...

Eclipse says the same thing, it cannot find UserModeImpl class. As far as I know, this class is sealed within portal-impl.jar, but I don't think referencing this jar within portlet/hook plugin is a good idea (liferay ant deploy task won't allow that anyway). What can I do with that situation?

Regards,
KG

[David H Nebinger, modificado 12 Anos atrás.]

Somehow you're accessing the implementation class (a no-no) when you should just stick w/ the interface class.

A full stack trace may help pinpoint where the failure is occurring...

[Krzysztof Gołębiowski, modificado 12 Anos atrás.]

Seems that Service Builder generates wrong code. SB generated class - RecipientsListPersistenceImpl - contains references to UserModelImpl. Examples and full stacktrace included below:

Examples from RecipientsListPersistenceImpl

public static final FinderPath FINDER_PATH_GET_USERS = new FinderPath(com.liferay.portal.model.impl.UserModelImpl.ENTITY_CACHE_ENABLED,
com.liferay.portal.model.impl.UserModelImpl.FINDER_CACHE_ENABLED,
com.liferay.portal.model.impl.UserImpl.class,
com.liferay.portal.service.persistence.UserPersistenceImpl.FINDER_CLASS_NAME_LIST_WITHOUT_PAGINATION,
"getUsers",
new String[] {
Long.class.getName(), "java.lang.Integer", "java.lang.Integer",
"com.liferay.portal.kernel.util.OrderByComparator"
});

public List<com.liferay.portal.model.User> getUsers(long pk, int start,
int end, OrderByComparator orderByComparator) throws SystemException {
...
SQLQuery q = session.createSQLQuery(sql);

q.addEntity("Portal_User",
com.liferay.portal.model.impl.UserImpl.class);

QueryPos qPos = QueryPos.getInstance(q);

qPos.add(pk);
...
}

Yep, that's the problem alright. SB is trying to use the internal classes for which it has no access.

[Krzysztof Gołębiowski, modificado 12 Anos atrás.]

Thanks for your help David, I submitted this bug to Liferay JIRA (http://issues.liferay.com/browse/LPS-26849).
