Should I use Ajax for this? But I haven't used it before.
So any simple solution for the above situation? Thanks.

I am trying to craete a JSF page. I want to get the user input either from a drop down list or input text field
If the user starts typing in "input text" then the drop down list should be disabled. Otherwise if the user selects a name from the drop down list, then input text filed should be disabled. I tried as follows. But it doesn't work properly. Can anyone give me some suggestion?

<h:selectOneMenu id="selectName" onchange="submit()" valueChangeListener="#{Bean.tprocess}" value="#{Bean.currentName}" > <f:selectItems value="#{Bean.sampleNameList}"/> </h:selectOneMenu> <h:inputText id="input the Name" onchange="submit()" valueChangeListener="#{Bean.tprocess}" disabled="#{selectName}" value="#{Bean.currentName}"/> <h:commandButton action="#{Bean.selectRunDetail}" value="Next>>"/>

public String process(ValueChangeEvent e){ return "ChooseNamePage"; } public String tprocess(ValueChangeEvent e){ return "ChooseNamePage"; }

Hi,
I am constructing an url like below and trying to get the JSON objects.

String url = "http://test.ntu.edu.sh/libs/sample" + " " + "name/list/json"; SimpleClient c = new SimpleClient(); c.setWsUsername("test"); c.setWsPassword("test"); c.setElmServiceUrl(url);I get the following error.

Error retrieving library list java.lang.IllegalArgumentException: Invalid uri 'http://test.ntu.edu.sh/libs/sample name/list/json': escaped absolute path not valid

If I paste the above URI on an browser, it goes through and I get the JSON object.
How to introduce a white space between "sample" + " " + "name" as the above construction doesn't pass.
Many Thanks in advance.

Hi Ravi,
Thanks for your response. But I want to just display the table in a dataTable and also have to bind these beans for further manipumation.
I also tried dataList as below:
<t:dataList value="#{UserBean}" var="loc" layout="unorderedList"> <h:column> <t:outputText value="#{loc.lane2A}"></t:outputText> </h:column> </t:/dataList>

The results are still displayed as ".[HI, BYE] "
Regards

Is there anyway that I can display my list horizontally? Thanks.

I also need some help in binding these beans..Thanks.

My list of item to be displayed in in an arrayList. I tried datable as bleow:

Initially I have just one set data for each row to be displayed as below:
lane2A is an arraylist with just one item.
<h:selectOneMenu id="GId2" value="#{UserBean.G_2}"> <t:selectItems value="#{UserBean.lane2A}" var="cur2" itemLabel="#{cur2}" itemValue="#{cur2}"/> </h:selectOneMenu>

now lane2A might have more than 1 tem and still items in an arraylist
I am trying as follows but the list is displayed horizontally as [HI, BYE]

<h:dataTable value="#{UserBean}" var="loc"> <h:column> <t:outputText value="#{loc.lane2A}"></t:outputText> </h:column> </h:dataTable>

How to display a horizontal list as
HI BYE

Thanks.

Hi,
Since I didn't get any resonse, may be my query is not very clear.
Right now , I query a database and displau them as jsf components as below. (8 rows and 3 columns)
But my new query each row might contain either 1 set of 3 columns or 4 sets of 3 columns. How to dynamically include tehse data to be displayed? A small example would be very very helpful. Thanks again.

Hi,
I am a beginner in java programming. I query a database and display them in a fixed set of jsf components in a jsp page.
Basically its a 8 rows table and 3 columns table. And hence I have displayed as below simply.
Each row had only 3 columns to display as below.
<h:outputText value="#{UserBean.testSelected_1}" /> <h:outputText value="#{UserBean.analysis_1}"/> <h:outputText value="#{UserBean.testBasesSelected_1}"/>

Now I have something new to learn. for each row in a table, there might be 4 or 8 (dynamic number) of rows and 3 columns for each row (inside) to be displayed. How to display them. Can any one show me a very simple example? I would really appreciate any help as I am getting my hands in java after a long time. Thanks.

Hi I am trying to catch exception for missing JSON objects
try{ JSONObject jo = new JSONObject(c.outputByGetService()); JSONArray ja = jo.getJSONArray("array"); for(int i=0;i<ja.length();i++){ JSONObject lane = ja.getJSONObject(i); int laneId = lane.getInt("laneId"); ArrayList a = new ArrayList(); a.add(lane.getString("name")); } }catch(Exception e){ e.printStackTrace(); }

sometines "names" may not be found. Exception is being printed as org.json.JSONException: JSONObject["name"] not found.

But I want to add a "null" in the aaray list "a" and move on to next item in the for loop. How do I implement it. Thanks.>

Thanks. Henry. I have changed my code as suggested.

Hi Henry,
I have declared them as in line 1.
private String lib1,lib2,lib3,lib4,lib5,lib6,lib7,lib8;

I want to loop these variables without writing like

lib1 = this.lan[0].toString(); lib2 = this.lan[1].toString(); lib3 = this.lan[2].toString(); lib4 = this.lan[3].toString(); ..

I don't get any errors in the above lines. Where as I am trying do this inside a for loop.

Hi Simon,

error says "can not find symbol lib"
