How to execute the Quartz scheduler job only in master author node - AEM/Adobe CQ5

How to execute the Quartz scheduler job only in master author node -  AEM/Adobe CQ5

While we are deploying the scheduler in Adobe Experience Manager(AEM), the scheduler will be active in master/slave author nodes and all the publish nodes(based on our deployment configuration).

But sometimes there will be scenario the scheduled job should be only executed in master author node.

The below code snippet can be used to restrict the job getting executed only in master author node.

@Reference
SlingRepository repository;
private void sampleScheduledJob() {
       if(isRunMode("author") && isMasterRepository()){
            //execute the job functionality here
       }
}

private Boolean isRunMode(String mode) {
        Set<String> runModes = slingSettings.getRunModes();
        for (String runMode : runModes) {
                if (runMode.equalsIgnoreCase(mode)) {
                         log.debug("Current Runmode is : " + runMode);
                         return true;
                 }
        }
        return false;
}
               
public boolean isMasterRepository(){
          final String isMaster = repository.getDescriptor("crx.cluster.master");
          log.debug("isMaster.."+isMaster);
          return StringUtils.isNotBlank(isMaster) && Boolean.parseBoolean(isMaster);
}
               


  


The Admin console is not up/accessible – Oracle SOA Suite

The Admin console is not up/accessible –  Oracle SOA Suite

We were facing a strange issue in our Oracle SOA Suite production server in Solaris, we could not able to access the admin console even though the server is started properly and there is no error in the log file.

We were able to telnet the admin server listen address from Admin server node but not able to do it from other nodes.

The root cause of the issue is with Gateway server, the admin server listen address is not listed on the Gateway - the gateway server is not online (the servers listen address is configured in Gateway).

After Solaris admin team made the Gateway server online, we were able to see the admin server listen address listed on the gateway.

After restarting the admin server we were able to access the console page.

The following command can be used for checking the Gateway server status

 netstat –r

org.osgi.framework.ServiceException: Service cannot be cast: javax.servlet.Servlet - Adobe Experience Manager(AEM)

org.osgi.framework.ServiceException: Service cannot be cast: javax.servlet.Servlet - Adobe Experience Manager(AEM)

I was getting the below exception while invoking the servlet from Adobe Experience Manager(AEM) bundle.

15.02.2015 20:58:11.615 *ERROR* [FelixDispatchQueue] FrameworkEvent ERROR (org.osgi.framework.ServiceException: Service cannot be cast: javax.servlet.Servlet) org.osgi.framework.ServiceException: Service cannot be cast: javax.servlet.Servlet

at org.apache.felix.framework.BundleContextImpl.getService(BundleContextImpl.java:468)

 The root cause of the problem is different versions of servlet API classes are loaded by two different class-loaders.

To fix the issue make sure <scope>provided</scope> is added for the Servlet API dependency in POM.xml

<dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>servlet-api</artifactId>
      <version>2.4</version>

com.google.gson,version=[2.2,3) -- Cannot be resolved in bundle - Adobe Experience Manager(AEM)

com.google.gson,version=[2.2,3) -- Cannot be resolved in bundle - Adobe Experience Manager(AEM)

I was able compile and  deploy the bundle successfully with gson dependency but the bundle is not getting started with the error "com.google.gson,version=[2.2,3) -- Cannot be resolved in bundle" in Adobe Experience Manager(AEM)

The root cause of the problem is the gson jar is not available in the server for bundle access.

This issue can be resolved  by following any of the below approach.

1. Export the gson  package - com.google.gson.*

<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.2.4</version>
<scope>compile</scope>
</dependency

<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-Activator>com.sample.activator.Activator</Bundle-Activator>
<Import-Package>*,com.sample.*</Import-Package>
<Export-Package>com.sample.*,com.google.gson.*</Export-Package>
<Bundle-SymbolicName>com.sample</Bundle-SymbolicName>
<Bundle-Vendor>Sample</Bundle-Vendor>
<Bundle-Category>Sample</Bundle-Category>
<Embed-Directory>dependencies</Embed-Directory>
<Embed-Transitive>true</Embed-Transitive>
</instructions>
</configuration>
</plugin>

2. Add the gson jar in the bundle class path

Specify the gson dependency scpes as compile or runtime(compile is the default scope)

<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.2.4</version>
<scope>compile</scope>
</dependency

The gson jar will be included in the bundle classpath.

The dependencies with what are all the scopes are included in the bundle classpath is configured in maven-bundle-plugin

<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>2.3.7</version>
<configuration>
<instructions>
<Embed-Dependency>*;scope=compile|runtime</Embed-Dependency>
<Embed-Directory>OSGI-INF/lib</Embed-Directory>
<Embed-Transitive>true</Embed-Transitive>
</instructions>
</configuration>
</plugin>

Expected a string but was BEGIN_ARRAY at line 1 column - Gson

Expected a string but was BEGIN_ARRAY at line 1 column 

I was receiving "Expected a string but was BEGIN_ARRAY at line 1 column" error while deserializing the json string to java object using Gson.

Model class:

public class EmailGroup{
private String type;
private String id;
private String name;
private String permissions;

public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPermissions() {
return permissions;
}
public void setPermissions(String permissions) {
this.permissions = permissions;
}
}

JSON Response:

{"emailGroup":{"type":"EmailGroup","id":"1","depth":"minimal","description":"","name":"sample","permissions":[2,5,4,3]}}

Gson gson = new Gson();
EmailGroup obj = gson.fromJson(jsonstring, EmailGroup.class)

The root cause of the exception is the permissions attribute defined in the model class is of type String but the type of permissions in the jsonstring is List.

To fix the issue convert the type of permissions in the model class to List<String>(type string will change based on the type of the list entries)

public class EmailGroup{
private String type;
private String id;
private String name;
private List<String> permissions;

public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public List<String> getPermissions() {
return permissions;
}
public void setPermissions(List<String> permissions) {
this.permissions = permissions;
}
}

The root cause of the problem is corruption of the embedded LDAP user store.

Steps to resolve the issue:

Stop all servers in the domain and backup the <<SERVER_HOME>>/data/ldap for all the servers including managed server.

Copy the ldap folder from the previous server backup or other working environment from same location to all the servers.

Restart the servers.
