This should solve your problem

i think we can do this by finder method but i dont how to do this, if someone can help

In service.xml you can entry like

<finder name="Name" return-type="Collection">
<finder-column name="columnName" />
</finder>

then ant build-service

Then generated LocalServiceimpl you need to write method like

public List<Organization> getOrganizations(long[] organizationIds)
throws PortalException, SystemException {

List<Organization> organizations = new ArrayList<Organization>(
organizationIds.length);

for (long organizationId : organizationIds) {
Organization organization = getOrganization(organizationId);

organizations.add(organization);
}

return organizations;
}

Yeah. this should work, but what will be the cost?...
The suggestion means establish a connection in each iteration and closing it.
That's too expensive, and cannot be consider a decent answer.
Is there some other way to accomplish this without having to pay this penalty?

First, you would be using a connection pool so it is not that expensive.

Second, you could always implement using a dynamic query in your xxxLocalServiceImpl class:

public List<organization> getOrganizations(final List<integer> organizationIds) throws SystemException {
    DynamicQuery dq = DynamicQueryFactoryUtil.forClass(Organization.class, getClass().getClassLoader());

    dq.add(PropertyFactoryUtil.forName("organizationId").in((Collection) organizationIds);

    List<organization> orgs = organizationPersistence.findWithDynamicQuery(dq);

    return orgs;
}</organization></integer></organization>

I like the dynamic query answer better
