StackOverflowError - when trying to run a JSP Page in JDeveloper

Hello all,
I am experiencing an error when I try to run a .jspx page in JDeveloper (10.1.3.3). Below is the error I am getting. Any idea where I need to look to resolve this memory issue?
{color:#ff0000}INFO: Unable to dispatch JSP Page : Exception:oracle.jsp.provider.JspCompileException: {color}

{color:#000000}Thank you kindly,
Christine{color}{noformat}

I don't see any errors or warnings in the Structure. I am going through the Veeva Vacations example from the WebCenter Demos and Samples page (http://www.oracle.com/technology/products/webcenter/owcs_10132_demos.html). There is nothing complex about the page it just contains an ADF Read-only table based on a Database table. I was able to run it successfully and then another time I ran it I got that error. It seems to me as though it is a memory issue as opposed to a page error. I am just not sure where to look to allocate more memory.

Copy the jdev_home/jlib/redist/uix2_install.zip file to
jdev_home/jdev/redist folder . It will overwrite an existing uix2_install.zip file.
Close and open the Jdeveloper IDE. It will prompt you for upgradation of projects. Press OK button in response.
Now you should be able to run the JSP pages.

You're right, that ws another fix I tried. There is no fix fo
rthe issue described, but it still seems like an old issue. My
class paths are short. Here is my jvm.config (pretty standard):
# VM configuration
# Where to find JVM, if {java.home}/jre exists then that JVM
is used
# if not then it must be the path to the JRE itself
java.home=I:/JRun4/jre
# If no java.home is specified a VM is located by looking in
these places in this
# order:
# 1) bin directory for java.dll (windows) or
lib/<ARCH>/libjava.so (unix)
# 2) ../jre
# 3) registry (windows only)
# 4) JAVA_HOME env var plus jre (ie $JAVA_HOME/jre)
# Arguments to VM
java.args=-server -Xmx1000m -Dsun.io.useCanonCaches=false
-XX:MaxPermSize=256m -XX:+UseParallelGC
-Dcoldfusion.rootDir={application.home}/
# commas will be converted to platform specific separator and
the result will be passed

Does your jar file include the libraries that you are "importing" into your code?
(Maybe javax.print.*)

This section from the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/tabbedpane.html]Using Tabbed Panes gives you a working example. Compare your code with the example. You have so many custom components that we can't tell you what the problem is. Try creating one tab at a time to determine which tab is causing the problem.

Please help. Got TopLink working, but now I can't run a JSP page

I am using JDeveloper 9.0.3.
I got TopLink working successfully. Meaning I can access the DB using my mapped TopLink classes from my java code in JDeveloper.
However, now I can't even run the default .jsp page.
I am getting the error:
Error instantiating application at file:/C:/LBIT/LBIT-oc4j-app.xml: Error parsing data-sources config at file:/C:/LBIT/LBIT-data-sources.xml: Fatal error at line 0 offset 0 in file:/C:/LBIT/LBIT-data-sources.xml: The encoding "windows-1252" is not supported.
If I go change the "LBIT-data-sources.xml" file to "ISO-8859-1," as soon as I run the .jsp page (from JDeveloper) the "LBIT-data-sources.xml" file gets overwritten with a new one that contains the "windows-1252" encoding line again.
What can I do to fix this???
I know someone else has run into this problem!!!
Please help. Thanks so much.
Andy

You could change the encoding by doing the following.
Stop Embedded OC4J Server (Run | Terminate | Embedded OC4J Server)
Tools | Preferences
Select Environment
Change the Encoding to ISO-xxxxx
Click OK
Run your JSP now.
Atleast this should fix encoding generated into data-sources.xml

Not able execute or run a OAF page from JDeveloper

I am trying to run an OAF page in JDeveloper. I am getting the below error message.
You are trying to access a page that is no longer active.
- The referring page may have come from a previous session. Please select Home to proceed.
All Framework Pages should have a Function defined on the page when MAC Lite is enabled and the URL MAC Check fails.
I thought if I run the JRAD file directly, JDeveloper was not able to create the session. So I tried running the OAF tutorial's "test_fwktutorial.jsp".
JSP page runs fine. When I click "Hello world" or other link which invokes an JRAD page then I am getting the above error.
Can anybody help me.
I also checked the project settings.
Project Settings -> Common -> Oracle Applications
1) MDS XML path ("C:\oracle\JDeveloper\JDev-CU2patch\jdevhome\jdev\myprojects")
2) MDS XML path from Libraries ("C:\oracle\JDeveloper\JDev-CU2patch\jdevbin\jdev\oamdsxml\fwk").
Thanks

Got the solution for this from the thread.

Hi,
Check whether all the relevant services are up. If the problem still persist then there might be some issue with your JDeveloper.

CS 3 Bridge crashes / freezes when trying to run the slideshow feature

A while back I deactivated Photoshop CS3 that was installed on my laptop. Then this past week I went to reinstall it again. One thing I noticed was that the PS-CS3 and Bridge Icons were still residing on my desktop. I went into the "add/remove programs" and sure enough there was PS-CS3 sitting there. So I tried to do an uninstall first. When I clicked the tab to do a remove program it just sat there. I contacted Adobe Tech support and they sent me the script to to an uninstall. It worked, the Icons went away and so I proceded to do a new install. I entered the serial numbers and activated it and all seemed well. Then I went into the Bridge, everything seemed ok there too. I was able to use the RAW converter, view thumbnails and the rest. Then I went to a specific folder where I had some files that were converted to JPEG to run the slideshow feature. That is when Bridge hung up and a few seconds later it closed the preview window that had opened for the slideshow preview.
Does this have something to do with the amount of RAM on my laptop? Or maybe the cache? I ask because I had never needed to use the slideshow feature until now and everthing seemed ok even prior to uninstalling and reinstalling.
I have 1 gig or ram... the hard drive is 350 gigabytes and there is a ton of room still available. The processor is ok. Oh also, I have Lightroom 2 installed on this machine too and it's slideshow feature runs fine. But I would prefer to use the slideshow feature in bridge.
Any suggestions will be greatly appreciated

As Sumit has mentioned above, this issue has been reported in java forums but no definite answers. Hence instead of waiting for replies, I would suggest to analyse the scenario. Start with a new Jdev workspace and create, run the helloworld example. If that works, move over to a create example which uses a EO as your error stack is showing the start of error as the EO source file. If this also works fine, then I can say that there is something wrong with the code setup you have done otherwise there is issue with the java installation.

and one index.jsp in the path jsfHello/
The index.jsp just forwards the control to the page inputName.jsp
the code snippet: <jsp:forward page="/jsp/inputName.jsf" />
When I try to access the application as below I can see the corresponding pages and it corresponding navigation:
http://localhost:8080/jsfHello/jsp/inputName.jsf ( When I input name and continue it navigated to the greeting page)
http://localhost:8080/jsfHello/jsp/greeting.jsf
When I try to access the application as below it doesn't work:
http://localhost:8080/jsfHello
http://localhost:8080/jsfHello/index.jsf
http://localhost:8080/jsfHello/jsp/inputName.jsp
Can you please let me know why and what is to be done to make my application work when I access the url as http://localhost:8080/jsfHello

Problem in running a jsp page on tomcat 5.0

hi....
i made a java class abc.java and then compiled it to get a java class file named abc.class in a package named pkg.
Then i copied this package in the classes folder of the WEB-INF folder in tomcat 5.0.
After that i created a jsp page in which i imported this class file. Now when i run the jsp page on tomcat 5.0 i get an error saying this:
javax.servlet.ServletException: pkg/abc (Unsupported major.minor version 49.0)
     org.apache.jasper.servlet.JspServlet.service(JspServlet.java:244)
     javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

Can anyone please tell me the solution to this problem?

Leads me to believe that you're compiling and targeting a java version that your tomcat installation doesn't support. What version of the JDK are you using?

Running my jsp page

When I try to run my jsp page I get the following exception. Why is this. My code for the jsp file is below this error. Thanks.
A Servlet Exception Has Occurred
org.apache.jasper.JasperException: Unable to compile class for JSPC:\Tomcat\jakarta-tomcat-4.0-b5\.\work\localhost\examples\jsp\dbaccess\dbaccess3_jsp.java:14: Type expected.

----------------- CODE ------------------
<%! Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); %>
<%@ page errorPage="error.jsp" language="java" import="java.sql.*" %>
<html>
<body bgcolor=#000000 text=#87CEFA>
<center>JSP Page that accesses a database and prints the results</center>
Test!!!
<% Connection con = DriverManager.getConnection("jdbc:odbc://url:port/oracle", "username", "passwd"); %>
<% Statement statement = con.createStatement();
ResultSet resultSet = statement.executeQuery("SELECT * FROM oracle"); %>
<P> The results are:
</P>
<UL>
<% while (resultSet.next()) { %>
<LI><% String myData = resultSet.getString(); %></LI>
<% System.out.println(myData); %>
<% } %>
</UL>
</body>
</html>

in case connecting to oracle database u have to have the drivers or the classes12.zip file in u'r classpath.
in case of any other database try specifying the class path correctly.
hopw this helps.
