Hi Experts,

I am getting null pointer while trying to fetch result via flexible search service. Have tried disabling search restriction as well, still it doesn't work. The same query runs perfectly in HAC. Have attached code sample with error code for your reference.

public List<AppNotificationModel> getMessageTemplateByCode(String code)<br>{<br>    LOG.info("code :: " + code);<br>    validateParameterNotNull(code, "Template code must not be null!");<br>    final StringBuilder stringBuilder = new StringBuilder();<br>    stringBuilder.append("SELECT {").append(AppNotificationModel.PK).append("} ");<br>    stringBuilder.append("FROM {").append(AppNotificationModel._TYPECODE);<br>    stringBuilder.append("} WHERE {").append(AppNotificationModel.CODE).append("} =?");<br>    stringBuilder.append(AppNotificationModel.CODE);<br>    final Map<String, String> parameters = new HashMap<>();<br>    parameters.put(AppNotificationModel.CODE, code);<br>    final FlexibleSearchQuery fQuery = new FlexibleSearchQuery(stringBuilder);<br>    fQuery.addQueryParameters(parameters);<br>    final SearchResult<AppNotificationModel> result = getFlexibleSearchService().search(fQuery);<br>    return result.getResult();<br>}

Error log:

The exception is thrown here: AppNotificationDaoImpl.java:37

In your code snippet there aren't line numbers: please, could you copy the line 37 ?

final SearchResult<BestAppNotificationModel> result = getFlexibleSearchService().search(fQuery);

This is line no 37 alemasetto

On debugging, I am getting getFlexibleSearchService().search(fQuery) method returned nullpointer exception.

That means getFlexibleSearchService is returning null, and you try to call search method from null, that cause the NPE.

Did you already add flexibleSearchService to the property in xx-spring.xml of that class or using @Resource(name="flexibleSearchService") in your java class?

Hi adiputera,

Have added the property in spring.xml. It is giving a runtime error not a compile time error. Below have added the code:

<alias alias="appNotificationDao" name="appNotificationDao"/><br><bean id="appNotificationDao" class="kw.best.core.dao.AppNotificationDaoImpl"><br>   <property name="flexibleSearchService" ref="flexibleSearchService"/><br></bean>

Installed Tenants were the root cause for this issue. Removed the tenants from properties file and it worked.
