JSP Code completion fails

The code "insight" isn't working when I edit JSP pages. The page has include directives that were wizard generated and the JSP compiles and runs successfully. I see no indication as to why it's failing. Does anyone know a solution to this?
-s-
ps. i'm running 9.0.3.1

Alrighty! I opened a TAR against this issue on metalink and the results are in!
This is what the support person had to say:
I test the Code Insight by editing Servlet and JSP files. Code Insight is activated for Servlet case but is not activated for JSP case after one or two lines success.
This issue and related have been filed in a few non-published bugs (e.g., 2944071). The problem will be fixed in release 9.0.5.12 according to the bug.
I hope this helps anyone else in the same boat.

JSP Code completion DOES NOT WORK in JDev 9.0.3.1

Does anyone know when the next release of JDev will be? We are seriously considering dropping the use of JDev due to the bugs it has. In particular, the code completion for JSP authoring simply FAILS! This is a very very VERY nasty bug, and we are pleading!!!
Thanks,

Code Completion on portal jsps & htmlb

Hello,
what I have to do to use the code completion within a portal JSP file ?
The htmlb taglib is referenced in te portalapp.xml as follows:
<property name="tagLib" value="/SERVICE/htmlb/taglib/htmlb.tld"/>
Are there other settings needed for the project in the NDS ? The help is only referencing the standard web.xml
Thanks.

Hi Christian,
    You have to add a reference in JSP as well. Here is a sample portalapp.xml and a .jsp page.
<b>Portalapp.xml</b>

    <property name="PrivateSharingReference" value="com.sap.portal.htmlb"/>

Apply trace on RAS and look for errors in the RAS logs at the same timestamp.
These errors come for various errors and tracing RAS would give us a better idea.
It might hapen that you observe these errors for reports which takes more than the RAS timeout to export the reports.
Post getting the RAS logs you can try below steps if we see timeout errors in RAS logs.
Copy clientSDKOptions.xml file from <BO install path>\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\java\lib to the machine where your app is running Open clientSDKOptions.xml and change CORBARequestTimeOut from 600000 to a value large enough to allow the report to render, for instance 1200000. Default value is 600000 (10 minutes)
Specify the location of the clientSDKOptions.xml file at run-time. In your JSP or Java files, use the Java method setProperty from the System class. Set the system property indicated by the ras.config key to the specified directory as: system.setProperty("ras.config","c:\temp"). This function call specifies that the clientSDKOptions.xml file in c:\temp is to be used for locating RAS servers.

Why does Google auto-complete fail in Firefox 17.0.1 when I type something in the search field there is no pull down list of options as I type?

When I type a word or term into the Google search bar the auto-complete fails; there is no pull down list of options for my search, only what I have completely typed in. I have to type in the complete word or term that I am searching for and then press return to get the results. I'm using a MacBook and OS X 10.7.5 Please help! This is so frustrating!

Note that websites may be using autocomplete=off to prevent Firefox from saving and filling autocomplete data as I posted above.
Did you check for that?
You can remove autocomplete=off with a bookmarklet.
* http://kb.mozillazine.org/User_name_and_password_not_remembered
If a site uses autocomplete="off" then look at this article for a bookmarklet to remove the autocomplete attribute.
* http://kb.mozillazine.org/User_name_and_password_not_remembered (bookmarklet)
You can paste this code in the command line in the Web Console (Web Developer > Web Console; Ctrl+Shift+K) and press the Enter key to verify if there is an input field with autocomplete.
*https://developer.mozilla.org/en/Tools/Web_Console
<pre><nowiki>var c=0,e=document.querySelectorAll('input[autocomplete],form[autocomplete]'),T='\n';
for(i=0;E=e[i];++i){T+='['+(++c)+'] '+(E.name||'#'+E.id)+' ('+(V=E.getAttribute('autocomplete').toLowerCase())+')\n';}

How to use enviroment variables in JSP code?

I�m developing a web server with JSP�s, and I need to move the application to others computers. I need to access to a directory, but I don�t know it because the user can install the Application in the directory he wants. So I need to access to that directory in the JSP code.
The directory is "C:\Program Files\....\tomcat\webapps\ROOT\upload". I have the CATALINA_HOME enviroment variable defiened as "C:\Program Files\....\tomcat\", so I need to use something like "CATALINAHOME\\webapps\upload\", but I don�t know how to mekr the JSP code to understand the enviroment variable CATALINA_HOME.
I�ve tried with %CATALINA_HOME%, but the Tomcat server doesn�t recognize it. How can I access to that directory?
Thanks (Sorry about my english)

My JSP�s are in: %CATALINA_HOME%\webapps\ROOT\
I wan�t to access to %CATALINA_HOME%\webapps\ROOT\upload\
My JSP code:
<% ...
String DPATH = "C:\\Program Files\\JBuilder7\\jakarta-tomcat-4.0.3\\webapps\\ROOT\\upload\\";
File newfile = null;
newfile = new File(DPATH+filename);
%>
I want the JSP to locate the directory \webapps\ROOT\upload\ without knowing the complete route "c:\Program Files\...", because I have the enviroment variable CATALINA_HOME with the value "C:\Program Files\JBuilder7\jakarta-tomcat-4.0.3\". SO the user of the aplication only has to set the CATALINA_HOME variable and the aplication should access the upload directory throught the CATALINA_HOME variable.
I can�t explain it better. Sorry.

Blutooth disconnect when using Skype, now completely fails to reconnect

I have been experiencing the following problem when accepting or placing a video call through Skype. This never happens when running any other software. My system is an ideaCentre B520 with the stock Bluetooth keyboard and mouse using a Broadcom BCM2070 device running firmware 6.5.1.2700 and a Microsoft Bluetooth Enumerator with firmware 6.1.7601.17889.
The Bluetooth mouse and keyboard disconnect during the call and will not pair or connect wit the computer (IdeaCentre B520). The only solution that I have found work, is to remove both devices from the device manager and reconnect with the physical Bluetooth buttons on the computer and the devices. I also un- and reinstalled Skype, but the problem continues, which might be a software issue.
However, today the computer completely failed to pair and connect with the devices. The pairing dialogue is displayed after pushing the Bluetooth button on the computer. I am prompted to press the corresponding buttons on the mouse and the keyboard and the dialogue completes (code number for keyboard is entered) with the message that the pairing was successful, but drivers may need to be updated. The new drivers are installed for the HDI devices as indicated by the bubble and the grey Bluetooth window light the devices as connected. The Bluetooth box will then go into a repeated flickering between connected and disconnected until both devices are deleted from the device manager terminal. Both devices continue to blink as if searching for the receiver.
I had to switch over to a wired mouse and keyboard to type these lines. But this defies the purpose.
I sincerely appreciate any suggestion you might have to solve this problem and get the devices to talk to one another again.
Thanks in advance.

You use wrong bluetooth software. The only one that should work is 6.4.0.2100. You can download it from Sony website. I know it may sound strange but I have tested them all. Give it a shot and see what happens.

MC container causes this code to fail...why ?

Hi
Flash CS5 as3
We have settlements named with suffix _Level2 such as e.g. Mitre'sGate_Level2 as well as _Level3 as MovieClips that are in a container MovieClip called Map_Collection.
The code below fails with the error shown if the code line shown in bold is used, it works with:-
var clipName :String = String(e.item[s]).replace(r,"")+currentLevel;             if the settlements are placed directly on stage.
The code identifies _Level2 or Level3 at end of button name e.g. DistrictA_Level2 and appends it to the dataGrid output on the MouseHover.
What should the code read to resolve this problem that we have poured heart and soul into for 2 hours ?
Error is:-
Map_Collection.Mitre'sGate_Level2
TypeError: Error #1010: A term is undefined and has no properties.
at BusMap_fla::MainTimeline/ShowSymbols()
at flash.events::EventDispatcher/dispatchEventFunction()
at flash.events::EventDispatcher/dispatchEvent()
at fl.controls::SelectableList/handleCellRendererMouseEvent()
at fl.controls::DataGrid/handleCellRendererMouseEvent()
Code is:-
dg.addEventListener(ListEvent.ITEM_ROLL_OVER,ShowSymbols);
function ShowSymbols(e:ListEvent):void{
makeAllVisibleF(false);
var r:RegExp = /\W/g;
for(var s:String in e.item){
//trace(currentLevel)
if(e.item[s]){
var clipName :String = String(e.item[s]).replace(r,"")+currentLevel;
trace(clipName)
this[clipName].visible=true;
trace(s,e.item[s])
function makeAllVisibleF(b:Boolean):void{
Mitre'sGate_Level2.visible=b;
UpperDowning_Level2.visible=b
//Map_Collection.Tamar Brook_Level3.visible=b;
Map_Collection.Mitre'sGate_Level2.visible=b;
This code works on sttmnts directly on stage.
I show here an extract of the code visible=b; that follows it. we have such for every sttmnt. The first two lines are for those not in the MC container.
if we use:-
var clipName :String = "Map_Collection."+String(e.item[s]).replace(r,"")+currentLevel;
which is our best stab after trying various options, it fails with error above.
My compatriot says, in code !!!
// This is what we want
Map_Collection.Mitre'sGate_Level2.visible=true
//This doesn’t work
Map_Collection.this[clipName].visible=true
//This works, when Mitre'sGate_Level2 is placed on the stage
Mitre'sGate_Level2.visible=true
//Placing Mitre'sGate_Level2 in movie clip Map_Collection How do we get it to work
We tried a variety of options, even replacing 'this' with Map_Collection.., my best stab, just what should the code be ?

Hi,
Not sure of that, (also now have edited csv to no gaps or apostrphes, still it fails) ...because the code I posted is the code we are successfully running in a test file where there is a dataGrid fed a csv with such as Mitre's Gate Collet's Reach etc. This code removes the apostrophes and gaps when user hovers datagrid, MC's spelt MitresGate etc are identified and appear, then hide again when another row is hovered. Note also as said, Mitre's Gate outside of MC Map_Collection is found and shows.
The code in this test file (which is 3 columns) is:-
import flash.net.URLLoader;
import flash.events.Event;
import flash.net.URLRequest;
import fl.data.DataProvider;
import fl.controls.DataGrid;
import fl.events.ListEvent
makeAllVisibleF(false);
var urlLoader:URLLoader = new URLLoader();
urlLoader.addEventListener(Event.COMPLETE,completeF);
urlLoader.load(new URLRequest("NamesWithNullCellsGapsApostrophes.csv"));
var dg:DataGrid
function completeF(e:Event):void{
    var dataS:String = e.target.data;
    var dataA:Array = dataS.split("\n").join("").split("\r");
    var dpA:Array = [];
    var itemA:Array;
var r:RegExp = /\W/g;
    for(var i:int=0;i<dataA.length;i++){
        itemA = dataA[i].split(",");
         dpA.push({"col1":itemA[0],"col2":itemA[1],"col3":itemA[2]});
var dp:DataProvider = new DataProvider(dpA);
    dg.columns = ["col1","col2","col3"]
    dg.dataProvider = dp;
dg.addEventListener(ListEvent.ITEM_ROLL_OVER,ShowSymbols);
function ShowSymbols(e:ListEvent):void{
makeAllVisibleF(false);
var r:RegExp = /\W/g;
for(var s:String in e.item){
if(e.item[s]){
var clipName :String = String(e.item[s]).replace(r,"");
this[clipName].visible=true;
trace(s,e.item[s])
function makeAllVisibleF(b:Boolean):void{
We have introduced to that the code by Kglad, or so we hope, that appends to the output from OnHover _Level2 or _Level3 depending on which District button is clicked on, DistrictA_Level2 or DistrictA_Level3.
Just to recap/describe what we are aiming at, a map has 6 districts, user clicks District A button named in instance DistrictA_Level 2and is taken to that District, a dataGrid appears and when user hovers a row, the settlements for that layer of the map, e.g. Mitre's Gate_Layer2 appear. csv just has Mitre's Gate. user clicks on DistrictA_Level3 button and hover will show Mitre's Gate_L
evel3 symbol.
Kglad code:-
var currentLevel:String="_Level2";
dg.addEventListener(ListEvent.ITEM_ROLL_OVER,ShowSymbols);
function ShowSymbols(e:ListEvent):void{
makeAllVisibleF(false);
var r:RegExp = /\W/g;
for(var s:String in e.item){
if(e.item[s]){
var clipName :String = String(e.item[s]).replace(r,"")+currentLevel;
this[clipName].visible=true;
trace(s,e.item[s])
and when asked how one gets the Level2 into that var when user clicks on e.g. DistrictA_Level2
we now have, for the 12 buttons we have named, reply from Kglad
:-• DistrictA_Level2.addEventListener(MouseEvent.CLICK, clickF);
DistrictB_Level2.addEventListener(MouseEvent.CLICK, clickF);
DistrictF_Level2.addEventListener(MouseEvent.CLICK, clickF);
DistrictA_Level3.addEventListener(MouseEvent.CLICK, clickF);
DistrictB_Level3.addEventListener(MouseEvent.CLICK, clickF);
DistrictF_Level3.addEventListener(MouseEvent.CLICK, clickF);
var currentLevel:String;
function clickF(e:MouseEvent):void{
currentLevel="_"+e.currentTarnget.name.split("_")[1];
for the moment we are focusing on getting it operational on just button DistrictA_Level2
As said works fine if MC Mitre's Gate sits on stage, so the apostrophy and gap stripping is working as is the appending of the wording after and including the _ from the District button ! Place the settlement MC into Map_Collection MC and it fails.

3.1EA2/EA1 : Code completion issues

Hi,
OS Win 7, JDK 1.6_11 shipped with SQL Dev, againts Oracle 9iR2.
I find lots of improvement on the new code completion feature.
However I also find lots of defects on it, here are they :
1. Code completion often offers long exhaustive list of possibility that cause the list to scroll pass the bottom part of SQL Dev instead of giving us a small window with vertical scroll bar in it.
2. Code completion does not offer field list on the following :
   select *
   from   mytable1 t
   inner join mytable2 x on x. -- does not show field list
   select *
   from   mytable1 t
   inner join mytable2 x on x.fi -- does not show field list starting with 'fi'
   select *
      from   tmp_bow_data_aloy1 x
      inner join
        select *
        from   tmp_bow_data_aloy2 y
        where y. <Ctrl + Space> -- does not show field list
   select *
      from   tmp_bow_data_aloy1 x
      inner join
        select *
        from   tmp_bow_data_aloy2 y
        where y.acct_card_no = x.   -- does not show field list
   update mytable1 t
   set    t. -- does not show field list
   delete from mytable1 t
   where t. -- does not show field list
   3. Code completion mix between statement although has been delimited with ';'
   select *
   from   mytable1 x;
   select *
   from   mytable2 y
   where <Ctrl + Space> -- shows all mytable1's fields as well as mytable2's fields
   Hope these would be fixed on next EA.

Buntoro

Add EA2 to title

Hi Vadim,
I can confirm most of the issues have been fixed on 3.1EA2.
Thank you for that.
As for now, this 'challenging case' is the one that I work with most of the time.
select *
from   departments x
inner join
select *
from   locations l
where l.location_id = x.
)I am still hoping for the fixed.
Btw, the 3rd problem on which code completion mix between statement although has been delimited with ';' is the one that bothers me a lot.
It certainly a showstopper for using the code completion.
You cannot hope anymore from the unreliable code completion since it will mess up with the query.
I would like to give a more straightforward case just by adding another query on top of it :
select *
from   employees x
inner join employees y on y.manager_id = x.employee_id;
select *
from   departments x -- here I put the same alias as employees
inner join
select *
from   locations l
where l.location_id = x. -- <Ctrl + Space>, hm... why department table showing these field list ???
)From the above example, you will notice that the 'challenging case' is displaying the fields from wrong tables.
It suppose to be from departments table, instead of the employees one above it.
Another problem also arise from above case.
4. Code completion does not work if there is 'failed to be parsed' statement above the current within the same worksheet.
select *
from   employees
where department_id = ; -- hm.... I forget what's id that department is. Okay, let me leave it here first, and query the department tables
select *
from   dep -- <Ctrl + Space>, wait.... why is it not working??FYI, 3.0 seems working nicely.
Hopefully this will be fixed too.

Buntoro

Netbeans Code Completion

I installed netbeans two days ago, and I'm really impressed! Since then, I have had to reinstall windows 2000 on my PC, and after reinstalling the J2SE 1.4.1 SDK and NetBeans 3.5, the javadoc part of the code completion doesn't work. I've tried everything I can think of, but it always says
"JavaDoc not found. Either javadoc documentation for this item does not exist or you have not mounted a filesystem that contains the source for this class. The javadoc documentation that is displayed in this box is generated from source files, not from compiled javadoc documentation."
Sounded simple enough, but I have tried mounting every set of source files I can find, to no avail. This is especially irritating as this worked automatically when I installed it the first time.
Browsing through the help located the following information:
"To see documentation for Java SDK classes, you must have the Java SDK sources mounted. If you are running version 1.4 of the J2SE platform, the IDE mounts the SDK sources automatically the first time you use code completion on a JDK class."
Well, I am running a later version that 1.4, but this does not seem to have happened. I have tried following the instructions to manually mount the SDK, but this has also had no effect.
Please can anyone offer any advise, as this is getting really frustrating.

I have the docs in a docs folder in JAVA_HOME. I have just tried mounting this directory specifically but it didn't work. The part of the error message that says
"The javadoc documentation that is displayed in this box is generated from source files, not from compiled javadoc documentation."
indicates that this is not the right approach.
The part that seems to be going wrong is the SDK mounting - this was supposed to be automatic, but although it worked the first time, does not appear to have happened.
Does anyone know what might cause this to fail, or how the SDK should be set up for NetBeans to locate it?

Re: bug in html:link code completion

You are right, code completion does not work in this case. But, the
html:link Smart Editor (in the Link Parameter group) allows you to select a
bean name/property for the paramName/paramProperty attributes.

Hi thereI have a form containing an object eg
StudentForm
Student student;
public Student getStudent();
public void setStudent();
In the JSP page, I type in
html:link action="/editStudent" paramName="" paramProperty=""
Edit
/html:link
Nitrox does not display any thing when I "Cntrl-Space" on paramName=""
neither on paramProperty=""
Hoepe this bug can be fixed in 2.0.

Please send a test case. I'm unable to reproduce this in a simple project in 9.0.3.1 or 9.0.3.2.
Is there entity inheritance involved?
Do your entity XML files mention _superAttr anywhere in them? If so, you might be hitting a known issue with 9.0.3 relating to entity inheritance at design time and the accessor attributes.

Hiding JSP codes. Pls help.

Dear experts,
After completion of web development, I have to upload my file to the hosting site.
Is there any way to hide the JSP code so that the System Administrator of the hosting site also cannot
view the code.

Hi iragavar,
HOW TO OBFUSCATE THE CLASS FILES
To Obfuscate class files you can use Obfuscators
Java compilers place uncessary symbolic information in your .class files that makes them extremely vulnerable to reverse engineering by leaving method and field names unaltered from the original source. Obfuscator removes this information.
There are number of obfuscators available in market, you can use any. You can have a look at few at the following URLs.

Hope this helps
