Liferay 6 Using Common Service Builder layer Error - BeanLocatorException - BeanLocator has not been set_问答_开发者

We are trying to use liferay service builder as a common layer for all our portlets. We have created a separate common portlet project where we are building the service using service.xml This generates a service.jar file for us. We are copying this jar to all portlets WEB-INF/lib dir.

When we run the portlet it throws following error on the logs and Portlet is temporarily unavailable message is displayed on the portlet.

I am sure that this approach should work seamlessly. But found several people complaining about it on liferay forums, but did not find any solution yet. Please let us know if you found a way to use service builder as a common layer and it worked for you.

We are using maven for building all portlet projects.

Liferay Version is 6.0.5 And we are using Spring Portlet MVC for our portlet development.

You have to build-service AND deploy the (Portlet-Hook) that is required for your current portlet, you can know it by see its name in liferay-plugin-package.properties file as:

required-deployment-contexts=[Portlet-Hook name]

I tryed anything written on that page, but nothing worked for me, until i added the project's version

to maven-pluginname in pom:

            <configuration>
                <autoDeployDir>${liferay.auto.deploy.dir}</autoDeployDir>
                <appServerDeployDir>${liferay.app.server.deploy.dir}</appServerDeployDir>
                <appServerLibGlobalDir>${liferay.app.server.lib.global.dir}</appServerLibGlobalDir>
                <appServerPortalDir>${liferay.app.server.portal.dir}</appServerPortalDir>
                <liferayVersion>${liferay.version}</liferayVersion>
                <pluginType>portlet</pluginType>
                <pluginName>${project.artifactId}-${project.version}</pluginName>
            </configuration>

and in liferay-plugin-package.properties:

   artifactId-version-deployment-context=artifactId-version

for example:

   portlet-sample-1.0-deployment-context=portlet-sample-1.0

where artifactId = portlet-sample

and version = 1.0

After all I i built services, and redeployed my war.

I came to the solution because I debugged:

com.liferay.portal.kernel.bean.PortletBeanLocatorUtil

where

BeanLocator beanLocator = getBeanLocator(servletContextName);

is called which always returned null without versionnumber...

I hope someone helps this.

I had a hard time finding a solution to this error so I will post what we did. The name of the portlet changed, built the service and when running the portlet throws the same error:

com.liferay.portal.kernel.bean.BeanLocatorException: BeanLocator has not been set for servlet context

In our case we had to remove the jar file from ../docroot/WEB-INF/lib/portlet-service.jar

We had a requirement to use something similar: Have a portlet (lets say Source-portlet) whose services will be used by other portlets.

So we moved the generated sourceportlet-service.jar from the Source-portlet's WEB-INF/lib to {tomcat_home}/lib/ext folder were other jars like portlet-service.jar etc reside.

The down side of this approach is whenever there is a change in the Source-portlet we would need to restart the server.

If the other portlet's are your custom plugin portlets than another approach would be to copy the generated sourceportlet-service.jar to other portlet's WEB-INF/lib. This approach does not work if you are using the service in a JSP hook.

Hope this would help.

The previous answer by Martin Gamulin is correct. If you have two separate web apps, one for Spring portlets and another with your Service Builder (which seems to be the correct way to do things in Liferay), then you need to ensure that your Spring portlets do not reference your ServiceBuilder classes during initialization.

If they do then depending on the order in which your app server instantiates your webapps (and in Tomcat you can't specify a startup order), the BeanLocatorException will happen every time the portlets webapp deploys before the builder webapp.

In our case this meant moving a XxxLocalServiceUtil.createXxx(0) call from the constructor of the portlet Controller to the relevant methods.

I had a a similar problem doing a maven portlet. First i did the portlet and then i put the service.xml

The issue was that the generator was looking for a portlet name that was not there i solved making expliciting the portlet name i wanteed the genrator to look for

in particular, to do this two pom nodes must be equal

project.artifatctId = (liferay creates a bean locator for this)

and

project.build.(liferay plugin).configuration.pluginName = the internal name of the portlet for the generator

as an example, a small exerpt from my pom.xml

<modelVersion>4.0.0</modelVersion>
<groupId>io.endeios</groupId>
<artifactId>ShowTheCats-portlet</artifactId><!-- ONE -->
<packaging>war</packaging>
<name>ShowTheCats Portlet</name>
<version>1.0-SNAPSHOT</version>
<build>
    <plugins>
        <plugin>
            <groupId>com.liferay.maven.plugins</groupId>
            <artifactId>liferay-maven-plugin</artifactId>
            <version>${liferay.maven.plugin.version}</version>
            <executions>
                <execution>
                    <phase>generate-sources</phase>
                    <goals>
                        <goal>build-css</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <autoDeployDir>${liferay.auto.deploy.dir}</autoDeployDir>
                <appServerDeployDir>${liferay.app.server.deploy.dir}</appServerDeployDir>
                <appServerLibGlobalDir>${liferay.app.server.lib.global.dir}</appServerLibGlobalDir>
                <appServerPortalDir>${liferay.app.server.portal.dir}</appServerPortalDir>
                <liferayVersion>${liferay.version}</liferayVersion>
                <pluginType>portlet</pluginType>
                <pluginName>ShowTheCats-portlet</pluginName><!-- TWO -->
            </configuration>
        </plugin>

ONE and TWo must be the same

Problem with BeenLocator with my spring portlet for me was that my portlet's spring context was getting initialized before liferay's spring context did.

I was using ClassName className = ClassNameLocalServiceUtil.getClassName(JournalArticle.class.getName()); in my constructor. LIferay's context was not loaded hence the error. I moved that piece of code to be called when (only that time) first request needed it. Problem was solved.

So do not depend on lifery during initialization of your portlet, do some kind of "lazy" wiring of dependencies to liferay.

Since you are using maven, try to make sure your war name equals to your portlet project name. After debug i've found that ClpSerializer defines _servletContextName which is equal to <artifactId> of war project. If you deploy artifact named artifactId-1.0.0-snapshot.war the context will be created with that name, but code, generated by servicegen expects it to be artifactId. Verify with your ClpSerializer.

I also had the same problem. I placed the following code in liferay-plugin-package.properties file of portlets which uses the service layer of common portlet. It worked for me.

required-deployment-contexts=common-portlet

It's better to copy the service.jar file to tomcat/lib/ext instead of all portlets WEB-INF/lib.

I did the following to solve the above problem:

Set the plugin config property pluginName in pom.xml to the correct context

    <plugin>
        <groupId>com.liferay.maven.plugins</groupId>
        <artifactId>liferay-maven-plugin</artifactId>
        <version>${liferay.version}</version>
        <configuration>
            <autoDeployDir>${liferay.auto.deploy.dir}</autoDeployDir>
            <appServerPortalDir>${liferay.app.server.portal.dir}</appServerPortalDir>
            <liferayVersion>${liferay.version}</liferayVersion>
            <pluginType>portlet</pluginType>
            <pluginName>XXXX-portlet</pluginName>
        </configuration>
    </plugin>

Optionally set the XXXX-portlet-deployment-context property in liferay plugin properties file or portlet.properties file

XXXX-portlet-deployment-context=XXXX-portlet

Re-Build the services
Verify if the generated ClpSerializer.java contains the correct contexts

` public static String getServletContextName() { if (Validator.isNotNull(_servletContextName)) { return _servletContextName; }

    synchronized (ClpSerializer.class) {
        if (Validator.isNotNull(_servletContextName)) {
            return _servletContextName;
        }

        try {
            ClassLoader classLoader = ClpSerializer.class.getClassLoader();

            Class<?> portletPropsClass = classLoader.loadClass(
                    "com.liferay.util.portlet.PortletProps");

            Method getMethod = portletPropsClass.getMethod("get",
                    new Class<?>[] { String.class });

            String portletPropsServletContextName = (String) getMethod.invoke(null,
                    "XXXX-portlet-deployment-context");

            if (Validator.isNotNull(portletPropsServletContextName)) {
                _servletContextName = portletPropsServletContextName;
            }
        } catch (Throwable t) {
            if (_log.isInfoEnabled()) {
                _log.info(
                    "Unable to locate deployment context from portlet properties");
            }
        }

        if (Validator.isNull(_servletContextName)) {
            try {
                String propsUtilServletContextName = PropsUtil.get(
                        "XXXX-portlet-deployment-context");

                if (Validator.isNotNull(propsUtilServletContextName)) {
                    _servletContextName = propsUtilServletContextName;
                }
            } catch (Throwable t) {
                if (_log.isInfoEnabled()) {
                    _log.info(
                        "Unable to locate deployment context from portal properties");
                }
            }
        }

        if (Validator.isNull(_servletContextName)) {
            _servletContextName = "upay-portlet";
        }

        return _servletContextName;
    }
