JDev903 custom tag (bug?)-JDev Team please respond

JDeveloper is continually hanging while working with custom tags. For example, I will select Add Tag and nothing will happen and JDeveloper stops responding. If I go to End Task, I am told that JDeveloper is waiting for a response, but by then JDev is just a gray window. This behavior becomes more frequent after a change, i.e. change a tag name, try to delete a tag or library. In fact, I have had to completely start over in the creation of a tag library when I notice a necessary change within a tag due to the hanging and disappearance of menu items. Please see previous post, Re: 10.1.3.1 xpath-functions.xml
Please look into this issue. Our team feels that custom tags could be a valuable tool, but we are RAPID and we don't have time to constantly shut-down and restart our IDE.
Thanks,
Deb

David,
One thing to try would be JPublisher from the command line. If your problem persists with JPublisher from the command line, then the bug needs to be filed against that product. If not, then the problem is with us.
In either case, please post your code so we can try to reproduce the error.
The JPublisher command line facility is documented in the JPublisher User's Guide, available from the Oracle8i 8.1.6 documentation pages on OTN.
Thanks!

JDev 9.0.3 - Working with Custom Tags Hangs JDev Repeatedly!

All,
I recently upgraded from JDev 9.0.2 to 9.0.3 because of the new support for JSP 1.2 and Servlets 2.3. As you probably know, JSP 1.2 includes additional support for custom tag development. Unfortunately, JDev 9.0.3 keeps hanging repeatedly when trying to work with a custom tag library. I have seen a couple other postings on this forum that indicate the fact that I'm not alone in this experience.
It seems that I am able to open a taglib and make a modification, and then save the taglib without a problem. However, if I attempt to make any further changes to that taglib again without restarting JDev, it just hangs JDev and I have to kill the JDev process and restart JDev. This has made JDev extremely frustrating and unusable developing custom tags. I do not have this problem with JDev 9.0.2, but that version does not support the additionally tag library functionality of JSP 1.2, which is supported by 9.0.3.
Is this a bug with 9.0.3? Does anyone know of a workaround I can try?
Thanks in advance,
Kyle Corley

JDBC/SQLJ Team - Please respond - invalid column type error

Hi, I have posted several messages regarding problems using SQL/J to call out a stored packaged function that returns a ref cursor, but haven't gotten one response. I have yet a new problem with it. JDBC team, please acknowledge!
I change the way I obtain a connection to the database from using the Oracle.connect along with a properties file, to now using a DataSource connection pool. As a result, I am constantly getting a SQLException: Invalid column type error. If I change the call to the stored function to a query in the SQLJ code, it's fine. What's going on??
A previous message I wrote stated I was constantly getting a "closed statement" error when I tried to call the next method of the iterator. I corrected this by removing the finally clause in the generated JDBC code that released the execution context.
Again, the environment is JDK1.2.2, SQLJ 8.1.6 SDK, JDBC 8.1.6 thin, all on NT.
Thanks
David

I am getting the same error message - Invalid Column Type. I am creating a Default Context by calling Oracle.getConnection(connection) passing in an instance of my own connection class that basically delegates to the OracleConnection. We wrapped the Connection so that we could trap and recover from lost database connections.
My environment is Solaris 2.6, Oracle 7.3.4 with Sqlj 8.0.5.
Thanks!

Simple questions for Oracle XML Team - please respond

1) Which class/methods should be used to obtain the content
model (mixed-content or element-content) associated with each
element declaration in a DTD? In other words, how do I know if a
particular element can have child elements and/or data in a
valid XML document, the frequency each child element can appear
under a particular element, and whether a sequence list or a
choice list was used to declare the element?
2) Do you have any bug reported so far for this part of Oracle's
parser made available in the last released?
Thanks,

Look at oracle.xml.parser.v2.ElementDecl class and then
getContentType and getContentElements methods.

REPOST(JDEV TEAM) Kindly respond!!!

SUBJECT: Strange Behavior in TOMCAT although it runs OK in Jdeveloper.
This is actually a repost and I am hoping that someone would answer:
I am encountering some strange behavior when I deploy my application to TOMCAT.
If I run in JDeveloper (webtogo) everything works fine but the behavior changes completely in TOMCAT.
Let me try and explain my situation here.
I have 3 jsps :
1.iss_listApps.jsp which is used to browse all the available records, allows the user to navigate to a specific record and edit or delete.
2. app_edit.jsp which is used to edit/delete a specific row passed from iss_listApps.jsp.
3. app_edit_post.jsp which is used to save the changes.
Note that I use an anchor ">Edit</a> to pass a row from the browser page to the edit page.
For your convenience I have listed all the source files below.
Now here are my problems:
Problem 1. If I run it in JDeveloper, I am able to browse the records and go to a specific record to edit and delete by clicking on the "Edit" anchor provided in the browser page.
I can also go to the edit page and backout out of it by not saving the changes. In that case I am back in my browser page and I can again click on the "Edit" anchor to go to a specific record.
However if I am in TOMCAT, I am able to browse and go to a specific record so long as I make changes to it and save it. If for any reason, I do not save a record and I go back to my browser
page then any subsequent calls to to edit a specific record goes to the same OLD RECORD that I did not save.
I fail to understand why? Maybe the "webtogo" server automatically refreshes when I click on the "back tab". If so, how do I automatically refresh a jsp page when I click on the "back tab" in TOMCAT.
I would sincerely appreciate any help on this.
Problem 2. I have an include jsp tag in my browser page. defined as
<jsp:include page="Message.jsp" flush="true">
<jsp:param name="colspan" value="2"/>
</jsp:include>.
This section of the code is currently commented out because if I uncomment it then it runs ok in JDeveloper but in Tomcat it causes the browser page to always navigate to the first record if I want to edit a specific record.
I would sincerely appreciate any answer on this.
Here are my source files:
1. iss_ListApps.jsp (browser page). Please see how the anchor is formed. It causes no problems
in JDeveloper.

I am using Internet Explorer 5.5.
When I run the application using JDeveloper/Tomcat, it uses the same browser ie IE 5.5.
I am not sure what you mean by "cache set" in the browser. Where do you find that information for a browser. I looked in "internet options","page setup" etc but couldn't find anything which talks about "cache set".
Thanks in Advance!

JPublisher problem - SQLJ Team please respond

I'm trying to use JPublisher to generate code for a PL/SQL package that contains functions with a REF CURSOR type return value. The REF CURSOR is declared in the package spec as a TYPE, NOT strongly typed.
(defined as:
TYPE qry_results IS REF CURSOR;
For some reason, JPublisher will generated classes for my object types used in the package, but it will not generated the java class for the package itself.
If I change the type of these functions, they generate.
The only mention of REF CURSORs I see in the JPub docs is no support for STRONGLY TYPED ones. Mine aren't, yet they don't get generated.
Is this supposed to work?? Or does JPub have NO support for REF CURSOR return values in a packaged function?
Thanks
David

I retried this using the command line, as well as JDeveloper 3.1.1.2. It does not work.
Here are the specs:
Windows 2000
JDK 1.2.2
Oracle 8.1.6
JDBC & SQLJ 8.1.6 (comes with Oracle 8.1.6)
The package looks like this:
CREATE OR REPLACE PACKAGE qry IS
TYPE qry_results IS REF CURSOR;
FUNCTION get_all_appliances RETURN qry_results;
END qry;
Body looks like this:
CREATE OR REPLACE PACKAGE BODY qry IS
FUNCTION get_all_appliances RETURN qry_results IS
results qry_results;
BEGIN
OPEN results FOR
SELECT app_id, usr_app_name
FROM appliances
ORDER BY usr_app_name;
RETURN results;
END get_all_appliances;
END qry;
JPublisher does its thing, but it DOES NOT produce any output. It doesn't give any errors or anything, but it doesn't give any output files either.
I figure it must not be able to construct a SQL/J iterator? I don't know what's going on.
Please let me know if this is supposed to work or not? Is there anything in my code that should be changed to get it to work? Do I need to strongly type the REF CURSOR? The Jpub docs say it doesn't support strongly typed REF CURSORs.
Please advise, thanks in advance! Also please define whether this is unsupported or a bug.

SetCustomDatum performance SQLJ team please respond

I am facing performance overhead when using Jpub generated

I am using 817 jdbc and jpub but my database is 816. I have seen

Need Help from JDev Team

Hi,
I posted a question here early yesterday and I haven't received any kind of reply yet!!! I understand if someone from this forum cannot help me... but I need the Jdev team to respond to me ASAP!!!!
I'm using JDev 3.2, trying to use the Source Control feature to connect to Repository 6i. I can connect without any trouble and I can see the work area and navigate through the folders (that were created by the owner), however when I try to click on any of the 'files' branches of the folder/file tree - I get this error.
ckron61.exe has generated errors and will be closed by Windows. You will need to restart the program. An error log is being created.
There are 3 of us who are trying to connect, one can do it successfully... two of us cannot. I also tried to connect and access those files on another machine and it worked as well.
All of our systems have been imaged the exact same way.
What could the problem be...
I appreciate your help.... thanks.

Hi Jolene,
I would recommend upgrading to the latest release of Repository, since it contains many bug fixes. I'm afraid I'm not sure what is causing your specific problem.
It's also worth making sure your OS is patched up to the latest service pack.
Oracle9i JDeveloper's support for Oracle SCM (aka Repository) is far more comprehensive than 3.2, so this is a good upgrade to make as well :)
About UIX, the best thing is probably to post a new message to the 9i JDeveloper forum. It's not an area I'm overly familiar with, but I'm sure someone else on that forum will be able to help you out.
Thanks,
Brian

Using a custom tag with a 2.3 servlet descriptor BUG?

Hi,
I just developed a Custom Tag and I'd like to use in my jsps.
If I add the jsp in my JDev project with the custom tag when I try to build the project I got this error:
Error(11): oracle.xml.parser.v2.XMLParseException: Invalid element 'listener' in content of 'web-app', expected elements '[context-param, servlet, servlet-mapping, session-config, mime-mapping, welcome-file-list, error-page, taglib, resource-ref, security-constraint, login-config, security-role, env-entry, ejb-ref]'.
It seems like when the jsp parser encounters the line with taglib it tries to parse the web.xml against a 2.2 version of the dtd. My web.xml begins with the correct dtd version (2.3). Can anyone tell me if this is a bug and eventually tell me how to solve it?
thanks,
Giovanni

I repost this issue again, now with a simple test case.
If I wrote a simple custom tag:
import java.io.IOException;
import javax.servlet.jsp.tagext.TagSupport;
public class MyCustomTag extends TagSupport {
public int doStartTag() {
try {
pageContext.getOut().print("FOO");
} catch (IOException ioe) {
pageContext.getServletContext().log(ioe.getMessage(),ioe);
return(SKIP_BODY);
with the associated tld:
<?xml version = '1.0' encoding = 'windows-1252'?>
<taglib>
<tlibversion>1.0</tlibversion>
<jspversion>1.2</jspversion>
<shortname>try</shortname>
<uri>try</uri>
<info>A short description...</info>
<tag>
<name>mytag</name>
<tagclass>MyCustomTag</tagclass>
<bodycontent>EMPTY</bodycontent>
</tag>
</taglib>
and a jsp using the custom tag:

all runs fine if I have a web.xml with the dtd version 2.2

I get the error I report in my last post. (the jsp doesn't compile) If I remove the custom tag from my jsp all works fine (filters, listeners,etc). In my project settings I use the 2.3 version of servlet.jar instead of the ServletRuntime that comes with JDeveloper.
Can anyone tell me how to resolve this issue (Using simple custom tag with a web application using the 2.3 servlet specs)?
Thanks in advance,

Jsp 2.0 and jdev 10g production (custom tags)

there are some examples at
http://otn.oracle.com/sample_code/tech/java/jsps/index.html
I have certian questions it would be great if some one would clear these for me..
In JSP 1.2 if we wanted to write the custom tag's we had tag classes that extend TagSupport or TagBodySupport and the doStart() and doEnd() tag with the evaluate body. I could spit out the complete html text on an encounter of a tag! but in the JSP 2.0 a doTag() seems to take care of the intracies! how??
Now with jsp 2.0 I want to do the same... say some thing like this ....
<tg:myTag list="${somelist}"></tg:myTag> and say in my tag handler class I know what to do with this list. May be I will create complete html code and will use jspWriter to write out the html inbetween these tags!!
I have downloaded the eStore example but this class
javax.servlet.jsp.tagext.SimpleTagSupport; is not imported. So I am not able to look at the SimpleTagSupport class.
If I am trying to run the example in jdev 10g production should I have to specify that I am using jsp 2.0 so that jdev knows not to use jsp 1.2? if so how can I do this.
Does all the examples provided use the OC4J standalone? Can I use the embedded oc4J instead?
regards.

After reading a bit more now I know how the tags work.
However from the example I see (eStore) an array called by name "products" is created and set on the jspContext. If I already have the list and want to pass on the list which is in a bean or a session or a request can I provide it this way.
<tag:myTag var=${bean.list}>
or
<tag:myTag var=${session.list}>
or
<tag:myTag var=${request.list}>in the .tld file I should specify the attribute var and whether it should be runtime evaluable.
and in the TagClass
private Collection var;
private String listName;
public void setVar(Colloection aList) {
this.var = aList;
public Collection getVar() {
return var;
public void doTag( ) throws JspException{
// do i always need to this next line ------
getJspContext( ).setAttribute(listName, getVar());
}so that in my .tag file I can use some thing like this
<c:forEach var="list" items="${item}">
<td>${item.subObject.name}</td>
<td>${item.subObject.value}</td>
</c:forEach>And finally... as and when a tag is encountered the .tag file contents corresponding to that tag is called to get the html text and all that text is printed out in the jsp page right (without the jspWriter "out"). How does the browser know when to stop? like doEndTag() function? are these functions implicitly called?
regards.

Bug in Weblogic 6.0 sp2 Custom Tag implimentation ?

          I 've got this wierd weblogic error in my custom tags:
          javax.servlet.jsp.JspTagException: Since tag class emc.blackbox.taglibs.validation.ErrorTag
          implements BodyTag, it cannot return Tag.EVAL_BODY_INCLUDE
          though my class is (And it doesnt implemnt BodyTag) :
          public class ErrorTag extends BodyTagSupport {
          private JspWriter writer;
          private String preHtml;
          private String postHtml;
          public ErrorTag() { }
          public int doStartTag() throws JspException {
          try {
          writer = pageContext.getOut();
          ValidationManager vm = (ValidationManager) pageContext.findAttribute("validm");
          if (vm.getErrors().length>0){
               writer.println(preHtml);
               String [] errors = vm.getErrors();
               for (int i = 0; i < errors.length; i++) {
                    writer.println(errors[i] );
               writer.println(postHtml);
               vm.clearErrors();
               vm.clear();
          catch (Exception ex) {
          return EVAL_BODY_INCLUDE;
          public int doEndTag() throws JspException {
          return EVAL_PAGE;
          public String getPreHtml(){return preHtml;}
          public void setPreHtml(String preHtml){this.preHtml = preHtml;}
          public String getPostHtml(){return postHtml;}
          public void setPostHtml(String postHtml){this.postHtml = postHtml;}
          Searching on the net I found this :
          http://www.mail-archive.com/[email protected]/msg00888.html
          Does anybody know any work around this ?
          I would appreciate any hints / suggestions ..
          Thanks,
          Amit


Amit,
          I was getting a similar error message! In the jsp 1.2 spec,
          EVAL_BODY_INCLUDE should be usable with BodyTagSupport (as long as
          your .tld file doesn't contain <bodycontent>empty</bodycontent> for
          ErrorTag custom tag) .
          Since it apparently isn't working like it should, HERE IS A WORK
          AROUND that I found (with some Divine inspiration). Change this line:
          public class ErrorTag extends BodyTagSupport
          to
          public class ErrorTag extends TagSupport
          Hope it works for you too!! I'll look into this matter further to see
          if I can find some reason for the error.
