Code insight

hi there
can anyone tell me why in all java IDEs it is impossible to let the Code editor to invoke the code insight list whenever any char is typed.
this disability exist in all java IDEs. I use netbeans and eclipse and they both never allow you to extend this property(invoking the list of suggested code with more characters than the (.)) which is more essential than the whole IDE and I wait for every new plugin or new version to see if they have implemented it. but it seems like they have never used visual studio and seen how powerful it is.
can any one please write some plugin to fix this.
thanks,

Hi ,
still, how would you handle the case where a user types 2 letters and then pauses. The IDE would query the full classpath stack and find say 1000 hits. Because no user wants to see 1000 options to continue I assume you wouoldn't want to see the list of possible options and instead like to only code complete if the search returns a unique result. This means that the code complete check is a waste of resources to this time. So what's wrong with the option to press ctrl+enter whenever you please ?

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,
Jochen

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.

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.

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.

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.

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

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
InsightableOracleDatabase.fetch() time = 2216
SELECT 'SCHEMA' type, username owner, username object_name, null column_name, null column_id, null data_type
FROM all_users WHERE rownum <=50
and username like ?
union all
SELECT object_type type, owner, object_name, null column_name, null column_id, null data_type
FROM all_objects
WHERE object_type ='TABLE' and object_name not like 'BIN$%' and rownum <=50
and object_name like ?
union all
SELECT object_type type, owner, object_name, null column_name, null column_id, null data_type
FROM all_objects

i get this in console:

InsightableOracleDatabase.fetch() time = 705
SELECT 'COLUMN' type, owner, table_name object_name, column_name, column_id, data_type

In this case, the autocompletion works!
but in the first case - it doesn't do anything (((
This is when connected to a Oracle DB. (i just also have a teradata connection installed, but it is not connected. not sure why it appears in the console).
Please help!

Table aliases and Code Insight Completion

Oops, never mind, I see there are lots of threads on this... so the big question is: Does anyone know when this will be supported?
One thing I am noticing with the new SQL Developer is that if you use table aliases (as we do here) that Code Insight Completion doesn't work. For example, if I type the following SQL:
SELECT *
FROM My_Table mt
WHERE mt.
At the point where I put the dot (i.e. mt.) I would assume that code insight would drop down a box showing me the columns in the alias mt (i.e. My_Table). But nothing happens. Now if I put the full table name My_Table in there (i.e. WHERE My_Table.) then the drop down occurs. But not if you use a table alias - and putting the full table name in defeats the purpose of using aliases.
I know that in other SQL developers (such as PL/SQL Developer) this works fine and we are used to it working this way with aliases. Is there another way to get SQL Developer to do it this way? Or is this going to have to be a NEW feature later on?
Thanks.
Tom

Facelets and code insight for XHTML

Hi,
what about support for facelets and code insight for xhtml?
Thanks,
Uros.

Hi,
actually the templating mechanism is deployable in shared libraries, which means you should be able to reuse this outside of JDeveloper with the right libraries in place. The issue we found with Facelets is with the required binding references that we need for ADF to work in templates (though this is an Oracle specific problem for as long as JSR 227 isn't turned into a J2EE standard) .
Also, templates in JDeveloper 11 are referenced at runtime, which means they can be changed on the fly even after deployment and all pages will reflect them. Plus, you don't need to configure a new extension and filter to your JSF files/configuration making it more straight forward.
And yes, it can be deployed to other J2EE containers than Oracle- Not sure what the open source plans are, but I'll point someone from our Trinidad supporters to this thread to shed some light on what the Trinidad community has in the plans.
Your point for a common templating support is well taken (though I wished there would be something better than Facelets ;-) )

Code Insight Weaknesses / Issues

Congratulations Oracle, SQL Developer is a great product.
However, major gripe for our developers is the weakness of SQL Developer's code insight. For example
a) Package names and or proc / func names - all of the results are always in uppercase, rather than the case they were compiled with. Our packages and package procedures are mixed case, because they are far more readible that way.
1. I type P_ [press ctrl + space] I see :
P_ACCOUNTS
P_ACCOUNTPOSTINGS
P_UTILS
whereas I should see:
P_Accounts
P_AccountPostings
P_Utils
as this is the case of the compiled objects and this is how they appear in the navigator.
2. I select P_UTILS and get P_UTILS in editor, then type ".", I see :
INDEXEXISTS
CONSTRAINTEXISTS
OBJECTEXISTS
whereas I should see:
IndexExists
ConstraintExists
ObjectExists
b) Object type names would be clearer than a glyph. I'd prefer to see function MYFUNC, rather than a glyph and MYFUNC.
c) Code insight gives you no idea what parameter types are, and we can't seem to get the "parameter insight" facility working
I type MY and invoke code insight :,
SQL Developer would show : MYFUNC(PINPUT1,PINPUT2)
TOAD would show : function MyFunc(pInput1 integer, pInput2 integer) return integer;
and TOAD will maintain showing the parameters as I type them in. TOAD is far superior is this respect.
We hope you can address this for the next version.
Paul

This insight will be overhauled. It has many issues. Including what you have listed.

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.
