BUG: Code Insight

JDeveloper 11g Preview 2 on Windows XP
Code Insight is not refreshing properly. Two use cases:
1) Light grayed out indicator that member variable is not in use in a source file does not reliably disappear if you copy and paste exact member variable name into a method;
2) Redline indicators demonstrating code syntax errors do not disppear if you correct the error. It happens with all sorts of errors after their correction: exceptions not being thrown or caught, methods not being implemented, etc...I have to shutdown JDEV process and restart to get them to go away.
Nice interface if the annoying messages would go away when fixed.

It is likely a threading issue which means that it does not happen reliably -- however, next time I encounter it -- i will record my JDeveloper session and upload the recording. The amount of code is probably not feasible. However, I bet you could reproduce if you did the following things:
1) Create a couple of user libraries and import into your project;
2) Create some simple class files and use classes from imported jars;
3) create some member variables based on imported class files;
4) Use the "generate getters and setters" from member variables by placing your cursor on class file name (I notice that the default behavior is not consistent -- sometimes it shows all the getter and setter methods of every variable with 1 randomly checked --- other times none are checked -- other times all are checked) and generate;
5) continue doing this until you begin to get code insight errors to correct. Notice how the IDE begins to slow down as it appears to be processing much more in the background (also not good -- I am tempted to just turn code insight off and use the compiler);
Anyway -- stay tuned

BUG code insight declaration insert imports primitive types

Facing this in JDEV 11g 11.1.1.3, studio edition install, bundled jdk1.6.0_18, JDEVADF_11.1.1.3.PS2_GENERIC_100408.2356.5660
When using the 'Declaration Insert' code insight feature for method calls returning primitive arrays, JDev will add an import for the primitive return type. Using CTRL-ALT-V to do the same manually works correctly.
Steps to replicate:
- create a new class with a main method
- inside main method type this code:
"hello".
- the code insight window will appear automatically (if using default code insight settings). Press "CTRL-Space" to access "Declaration Insert".
- start typing "toCharArray", JDev will zero in on the toCharArray method which returns a char[], once selected, press enter to choose it.
- jdeveloper generates the following code:
char[] array = "hello".toCharArray();
which is correct, but also adds an import statement in the beginning of the class:
import char;
which does not compile.
- same behavior can be replicated with code like:
new BigInteger("1").toByteArray();
following the same pattern as above.

although this post is way old it could do with a decent answer.
some guidance can be taken from JSR26: UML Mapping for EJB
find it a www.jcp.org
also this research paper on consistency of reverse engineering between uml tools
http://citeseer.nj.nec.com/545406.html
Where Association is identified by looking at the types of all variables belonging >to a class (excluding method variables etc) and if the type of the variable is >non-primitive, than I have deduced it is an association relationship with that >class.
Would this be the right approach?Yes. You could also say that if it is a java.* type then it would also be an attribute.
Secondly I have noticed in JBuilder, it models dependency relationships by getting >all the Imports at the top of the java source file, is this right?? also I have >read that a dependency can be modelled by the variable types in operation >arguments (paremeterS ?)..JBuilder would be consistent with JSR26, and that's how i intend to implement in ArgoUml.
I would also appreciate if someone could clarify the difference betweeen >Composition and Aggregation for me and explain if it is possible to identify the >two relationships directly from java source code..Composition is a stronger form of ownership. the composed class is owned only by 1 class. Its lifetime is strongly linked to its owner - ie. it is not created before its owner and it is destroyed before its owner is.
eg. leg of a table.
Agregation is weak ownership. the owned class may be owned by several classes.
eg. a company is owned by many shareholders.
Last but not least, what about multiplicity ? am I right in thinking that an >instance variable is 0-1, an array declaration is seen as 0-n (fixed number) and a >Vector/ data collection.. is seen as 0 - * (any number)..sound right.

Slow code insight in JDev 9.0.3.1035

Hello,
sometimes when I invoke code insight in my Jdev it needs up to 30 secs to display. In this time JDeveloper is completely blocked and does not react to any keyboard or mouse input. It doesn't matter if the library is on a network drive or on the local harddisk, even with standard JDK-Lib (for example: java.text. ) this problem appears. And, this happens not always, sometimes the popup comes as fast as I set in JDev's preferences.
Has anyone experienced such a behaviour??
Thank you.
Christian

Interesting... I confirmed via. Metalink that there was a bug within JDev 9.0.3.1 that caused code insight to fail when editing JSP against at least an Orace Portal based project.. I'm not sure if it's related, but I have a feeling it might be. Are you by chance developing with Portal? I've also noticed no problems with code insight when i'm working with straight webapps built from Struts. Perhaps it's to do with the libraries in your project.
If you're on Windows, try the sysinternals file monitor program (www.sysinternals.com) and see if it's trying to access large files or something over the network.

Code insight problem when updating classes / jars

I have a problem with JDeveloper 9.0.3.2 build 1145....
I create a class with some methods and deploy it to a jar. I create another class in a different project and import the class from the original project. The code insight works fine. I now add a method to the original class and redeploy but the code insight in the second class know nothing about the new methods it until i restart JDeveloper!
Frustrating, any ideas ?

This has not been fixed in 9.0.5 actually, at least not the code insight
aspects. I just checked that it still reproduces under the latest 9.0.5
builds.
Since the bug 3034796 was originally filed for Javadoc issues, I've split
off the code insight issues (which you are hitting) into bug 3122056.
Unfortunately, there is no workaround for this problem. I'm sorry for the
inconvenience.

Code Insight not working properly - 9.0.3. preview

We are having some problems with Code Insight on the 9.0.3 preview version of JDeveloper. We have a couple of libraries which regularly change so when a new version comes along we simply overwrite the old one (they are saved in <JDEV_HOME>\jlib. In 9.0.2 all we needed to do was exit and restart JDeveloper and the new classes could be seen in Code Insight. This doesn't seem to be the case now although my code compiles OK. We thought that there might be a cache of some sort related to these libraries and what we've found is a folder under <JDEV_HOME>\lib called ojpd. There appears to be a file for each library in here. We renamed
the ones related to our libraries and this fixed our problems, but a new version was created. It seems to us that JDeveloper should be checking the modified date of any of these libraries and if so create a new 'ojpd' file. Is this a known bug?
Thanks
Ian

JDeveloper actually checks the number of bytes in a .jar file that it has stored parse data for. I believe there was a bug in the preview release involving this check. This bug has since been fixed.
To work around it in the preview you can delete the ojpd files corresponding to the archives you have changed. The files will be named after the archive, with a hash of the unique part of their path appended.
These files are only built for archives that are included in libraries, and reside under Oracle Home (the directory containing the jdev directory), or the User Home.

JDeveloper 10.1.3.2.0.4066
I've been working with JDeveloper 10.1.2 for a number of years and make good use of the code insight features. However I've recently started to evaluate 10.1.3.2.0 and I've noticed a disturbing change in behaviour. If I place the cursor in the middle of an existing method call in my code (i.e. get|Name()) and invoke code insight with Ctrl-Space the feature now truncates my method call to the point where the cursor is placed, leaving get|().
As far as I'm concerned, this is very BAD! I don't want any feature to EVER change my existing code without me performing a conventional commit action (left mouse-click or enter key)
When this feature was non-intrusive I frequently used it to check for other methods on the object instance, or even check the return type for the existing method call. I can't think of any scenario where I would want the code to change unless I actually select an alternative method from the menu.
Has anybody else had problems with this feature?
Can I configure it to behave as it did in 10.1.2?
What's the best way for me to feed back my discontent?
Does anybody else agree with me that this is not a positive enhancement?!
Matthew

Thanks for reporting, I confirmed this behavior in 10.1.3 and the 11 technology preview.
The good news are that in newer builds of 11 this has been fixed - so you shouldn't be seeing this in the future.
I filed a bug (#6165291) on this to see if we can get it fixed in a 10.1.3 patch.
(for now you can just press ctrl+z to return the code to its previous state).

Code insight is not available when eding jsp by using 10.1.3.36.73

I use 10.1.3.36.73 jdeveloper on windows to develop web application,
but code insight is easy not available when editing jsp 2.0.
I must restart jdeveloper and it still isn't often available.
ex. in jsp
ArrayList al = new ArrayList();
for (Iterator it=al.
Code insight is not supported for jsp or this is bug?

Do you still have any code error in your jdev editor? no matter the error is JSP or HTML (it is signed by little red box at the right of the window near scroll bar), code insight sometimes is not available.

Code Insight and mixed case PL/SQL identifiers

Let’s assume I hava a package “Test” with a procedure “DoSomeReallyHardWork”.
I would like code insight to complete a call of this procedure and preserve the original case.
I don’t like “test.dosomereallyhardwork” and I strongly dislike “TEST.DOSOMEREALLYHARDWORK".
Is there any way to achive this kind case preservation?
I recompiled my code with PL/Scope turned on, but it seems that all identifiers are stored in uppercase. Bug or feature?

The identifiers are case insensitve, so your code could as easily read
create or replace procedure TestProc is
ThisVarHasNoMeaning varchar2(100);
begin
ThisVarHasNoMeaning := 'Test';
THISVARHASNOMEANING := 'Other';
end TestProc
You only have one identifier, but can have multiple capitalizations. While it would be nice if the declaration was the 'definitive' one, it looks like they've gone the easy route and uppercased them all for consistency.
If you used _ (the This_Var) in your variable names, at least you could use initcap to pretty them up.

Code insight is not working correctly in Jdev 10.1.3 (preview) and java 1.5

The code insight does not work for me. I followed the advice of Steve Muench given here:
http://radio.weblogs.com/0118231/stories/2003/01/17/whyIsntMyCodeInsightWorking.html
but that did not change the problem. The problem seems to be related to new java 1.5 features. As soon as I start using generics the code insight is lost...
Any clues what is going on? I s this easy to fix?
-- example: (NOTE that iI use double (( )) to indicate generics definitions. the forum software would not let me put in the correct syntax!)
package mypackage;
import java.util.Set;
public class tester1
private Set ((Integer)) intSet = null;
public tester1()
intSet. ---- NO CODE INSIGHT POPS UP! (if i change to "private Set intSet = null;" it works)
public static void main(String[] args)
new tester1();
P.S.
Also, i noticed that the auto-import ist not working for the "Set((Integer))" line!

thanks for the info.
Hmm - too bad. I may have to switch to eclipse or something then, since my project involves some 1.5 parts and the missing code insights and import features are a real pain for me.
Cheers,

Jsp taglibs in include files not detected, throws errors, no code insight

I have a jsp which is included in all the other jsp. it looks something like this
taglibs.jsp
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
<%@ taglib uri="http://www.springframework.org/tags" prefix="spring" %>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
test.jsp
<%@ include file="/jsp/menu/taglibs.jsp"%>
<html>
     <head>
          <title>Tours</title>
     </head>
     <body>
<form:form commandName="testCommand">
               <form:hidden path="tour.firstname" id="tour.firstname" />
and so on.
I am having 2 problems
1. the jsp editor show errors all over the place saying
element path not expected
element commandName not expected etc.
2. no code insights.
but if i include the taglib def in test.jsp it dosn't show any error and also provides code insights. but seldom do people include all taglibs in all jsps.
is there a way for Jdeveloper to show code insights in jsp pages which includes a jsp or like xml schemas could be added at some place(tools-pref-xml schemas) and when used anywhere, would provide code insights.

am not sure, try with this
<jsp:include   .../>

Code insight not working in sql developer 1.1.0.23

i just downloaded today. insight options all checked in preferences section. popup time set to less than a second. i get nothing to work in sql worksheet or while modifying a package body.

Hello,
You should see things from this side sometimes ;-) It's a small team, working hard, very focused! Yes, there is indeed a sense of urgency and we are testing a patch SQL Developer 1.1 at the moment. There is always the battle between wanting to get an updated release to you, the community, quickly, and delaying to ensure what you get is good.
Code insight, performance and many other issues have been addressed in this patch.
As for your other point, we want the tool to be lightweight, easy to install, easy to use with a clear user interface. Perhaps there'll be a new battle when adding features, but that's the goal.
Regards
Sue

30EA2 code insight completion odities

update statements seem not to be supported by code insight completion for table name:
For example for table 'table_name':
type 'update table_' and press ctrl-space does not complete table name.
When table name is typed, completion for field names works.
Completion of select statements:
Type ' select ' (space is important)
Popup show 'select * from' among others, select 'select * from' and get:
'sSELECT * FROM'
This happens only if select is the only statement on the worksheet.

Try searching this has been answered.

No code insight for 1.5 SDK

I added the 1.5 SDK in the libraries and now JDev recognizes 1.5 classes and methods however code insight does not appear to work for the 1.5 classes.

Crap... belay that. It seems to be working after restarting Jdev.

SQLdeveloper on mac and code insight

Hi!
Just downloaded SQL developer 2.1.0.63 and running it on snow leopard. (BTW, for others out there, make sure that you unzip the file with the standard apple utility).
I cannot get code insight to work for an Oracle or a Teradata DB.
For Oracle, i type in SELECT * FROM <DB_NAME>. ctr+space and nothing happens. this is in sql worksheet and in newly created files.
BUT if i just type in SELECT, in a second it gives me select * from table autocompletion.
as for teradata, i only get autocompletion after select in newly created files, but in sql worksheet - nothing works at all.
any luck on this?

when in type in select * from DBNAME.
this is what i see in the console:
*...?aux tok2?, parse time = 16
Finished parsing = 0
