Liferay Web Service

[Pradip Bhatt, módosítva 11 év-val korábban]

Hello All...

I am developed 3 different portlet in Liferay 6.2.0m2. I am using Struts2 + Spring3.0.5 and Hibenate technology. All my these modules runs specifically and well.
Now My question is that how can I connect this my modules internally. is Liferay provides some mechanism to interconect these modules. Note that Here, in my case all these portlets are individual like one is PIM another Admin andother Recruitment... And Using Web Service is this possible??

I am not using Service Builder here...

I want to integrate all this three and become one System(HRMS).

Please help me on this.
Please reply me as early as possible.

Thankssssss in Advance...

One way to do it is to use <liferay-portlet:resourceURL> tag in your jsp page. This tag creates a link to other portlet's resource method.

Personally I'd use the LMB to have them message back and forth.

Thanks sir,

Example :
My requirement like fetching Job category from Admin portlet to Employee Information Portlet. It means data passing size may be become more.

Is it possible in this way?

[David H Nebinger, módosítva 10 év-val korábban]

You do not need to pass the whole content in LMB; in fact in normal messaging systems you'd pass a reference to the corresponding data and let the recipient find the actual message content. Saves the load on the messaging system and maintains performance levels.

Thankssss Sir,

Can you please give me small example which describe what you say???

Because I have no much knowledge about Liferay framework..

AS per my first point of view

You should have to use

<s:textfield name="<entityName>.<attributeName>" label="Name" value=""/>

in your jsp file.

Suppose :
Entity / pojo class :
class Student{
int rno;
String name;

// GETTER - SETTER

}

class YOUR_ACTION_CLASS
{
Student student;
// GETTER - SETTER of student

public void execute()
{
System.out.println("Name :" + student.getName());
System.out.println("Student Name :" + name);
}
}

jsp file :
<form action="YUOR_ACTION" method="POST">
<s:textfield name="student.name" label="Name" value=""/>
</form>

It will be work..

Hi Pradip

As per your suggestion I have implement new portlet but getting nullpointer exception at following point
System.out.println("Name :" + student.getName());

portlet.xml

Hello. I have the same problem. My project works for the 6.1.2 version without any problem. But when I change it to version 6.2, it stopped working sending values ​​submit sends "null". However, sending values ​​renderURL works.

<portlet:renderURL var="nameURL" windowState="pop_up">
<portlet:param name="struts.portlet.action"
value="/view/view/name" />
<portlet:param name="codigoOferta" value="${oferta.id}" />
<portlet:param name="tituloOferta" value="${oferta.titulo}" />
</portlet:renderURL>

Anyone know at what the problem is?.

Sorry for the english, I'm a translator.

[Jay Trivedi, módosítva 10 év-val korábban]

Hey Ranjit,

Put portlet name sapce before the name of elements of form:

<s:set var="portletnamespace">&lt;%=renderResponse.getNamespace()%&gt;</s:set>
<s:form action="addBook">
<s:textfield name="%{#portletnamespace}book.title" label="Book Title"></s:textfield>
<s:textfield name="%{#portletnamespace}book.author" label="Book Author"></s:textfield>
</s:form>

[Henrique Andrade, módosítva 10 év-val korábban]

Or you can add this in your liferay-portlet.xml:

<requires-namespaced-parameters>false</requires-namespaced-parameters>

I had a similar problem in Liferay 6.2.
