Only a type can be imported

[12年前 に Maxim Kovalev によって更新されました。]

Hi, All
I created liferay project portlet. It added the liferay hook, which overrides user_action.jsp
In the jsp I need to access your class Test.java which I added in src portlet. But when you call I get an error:

An error occurred at line: 15 in the generated java file
Only a type can be imported. test.Test resolves to a package

I really need your help

I think this Test.java is not present in your class path.

My problem is probably not the case.
custom_jsps \ html \ portlet \ users_admin \ edit_user.jsp I override the deploy when copied to the tomcat\webapps\ROOT\html\portlet \ users_admin, and the classes it needs are in the portlet. How do I make them visible?

I saw on the forum that this problem can be solved by renderURL
in custom_jsps \ html \ portlet \ users_admin \ edit_user.jsp I added:

<liferay-portlet:renderurl plid="10163" portletname="user-reg_WAR_user-reg-portlet" var="userRegisterPortlet">
<!-- liferay-portlet: renderURL--></liferay-portlet:renderurl>

That is, when you call the portlet should work its ClassLoader, but the problem persists

maybe I'm wrong?

I know that almost three months have passed, but for other folks who will find this question in the future:
It is not possible to access classes from one portlet inside other portlets, due to different ClassLoaders. Think of it as every portlet/hook is inside its own sandbox.
When you want to access classes from other portlets it is just poor design. So change your strategy.

FYI: to access classes defined by yourself from any other portlet the only thing you can do (as far as I know) is prepare EXT plugin and add new classes to it.

Hi, even if your statement is true, I got the error :

Only a type can be imported. x.y.service.XServiceUtil resolves to a package

When accessing to my service in my override jsp.

As Maxim Kovalev, I created Iiferay hook to override some struts action : /blogs/edit-entry
(I follow this page : http://www.liferay.com/web/mika.koivisto/blog/-/blogs/7132115 )

My liferay-hook.xml :

<hook>
	<custom-jsp-dir>/META-INF/custom_jsps</custom-jsp-dir>
	<struts-action>
		<struts-action-path>/blogs/edit_entry</struts-action-path>
		<struts-action-impl>x.y.EditBlogEntryAction</struts-action-impl>
	</struts-action>
</hook>

I override /html/portlet/blogs/edit_entry.jsp and added the import :

<%@ include file="x.y.service.XServiceUtil" %>

There is a single portlet;
Any suggestions?

Hi Tom,

You are overriding portal's jsp, which will run in portal's classloader. So it cannot access the services in hook(hook's classloader is different). You have to move your custom-service.jar in global classpath for the issue to get resolved.

Hi Sandeep,

Thanks for the precision.
Indeed, I move my custom-service.jar in tomcat's ext lib and it works.

Regards,
Tom
