Tomcat 5.0 and JDK 5.0 ?

Is it possible to build my app with JDK 5.0 and deploy to Tomcat 5.0? (Right now Tomcat errors because the class file version is 49 rather than 1.4's 48.) Thanks.

You have both 1.4 and 1.5 installed on your machine?
Remember Tomcat is a java process as well.
It is probably running using under 1.4.
Check
1 - your JAVA_HOME variable
2 - the startup file for tomcat - which version of java does it invoke?

The two means of including files are different in their approach.
Using <jsp:include .../> compilation of the included jsp is done at run -time not during compilation.
Using <%@ include .../> compiles at compile time.
Looking at the error it seems that the method JspRuntimeLibrary.include is not being found which suggests that you may have a classpath problem. Check that there is not a servlet.jar in the classpath that is from a earlier spec than the one provided with Tomcat.

class file has wrong version 48.0, should be 47.0Tomcat looks like it's using 1.4.2_13.
I have two pieces of advice:
1 - synch up the JDK you use to compile and the one that Tomcat uses to run.
2 - upgrade both your JDK and Tomcat. The current production versions are 6 and 6, respectively. you're far behind.

Tomcat 4.0 and Oracle 10g takes 100% CPU and grinds to a halt

Hi, I have a system to support that is currently running on Tomcat 4.0 on a Windows Server 2003 R2 SP2 machine with 3.06Ghz, 4Gb Memory, 2Gb Page file connecting to an Oracle 8.1.6 database on a Windows NT 4 virtual server with 3.2Ghz, 1152Mb Memory, 1536Mb Page file.
I have another Windows virtual server 2003 R2 SP2 machine with 2Gb of memory and a 4Gb page. This server has Tomcat 4.0 and an Oracle 10.2.0.3.0 database. I have made sure that the Oracle 10g classes12.jar file is used.
I am trying to run the application on the new server. In some tests I had users logging on one by one for the first 5 users - performance was great and the application ran faster than the current live system. When I then got another 10 - 15 people logging on the CPU stuck at 100% on the server, even exploring the server was almost impossible, and the application slowed down to unworkable.
We dont know if the problem lies with the very fact that we are trying to connect to a 10g database which is cost based and the application was written using rule based Oracle 8. Or is it the virtual server? Or is it the fact that we have both the application and the database on the same server.
I dont know if it is possible to have another Tomcat4.0 server running on our live server but connecting to the 10g database - what would happen with classes12.zip and classes12.jar? would there be a conflict?
I would really appreciate some help here. You should know though that I am not a hardened java programmer - I can dabble, but am an Oracle Forms, Reports, Discoverer, SQL person by trade. I am also a trainee DBA, so again am not an expert by any means.
Thanks in advance for your help

We're up to Tomcat 6. The important difference is the JDK supported. What JDK are you using for Tomcat?

If you find that those are drifting up over time, it's likely that the code isn't closing resources properly.

Start monitoring your Oracle connections and cursors to see what's going on. Install some filters to get raw timings on your Java calls. Without data, you're guessing in the dark.

Urgent Solution needed--Problem in JSP compilation with JDK 1.5 and JDK 1.6

Hi,
I m using JDK 1.5 and Tomcat 5.0 the problem is that after starting server when I m going to access my application at that time instead of displaying HomePage it directly display the blank page on screen.
After analyzing tomcat log I have found that there was a problem with JSP page compilation.
The exception logged in Tomcat Log is given below
An error occurred at line: 1 in the generated java file

After getting this kind of error I have analyzed my code furhter then I came to know that there was problem with static include tag.
In my jsp page I have used following line which is the main cause of error
<%@ include file="top.jsp" %>If I ommit this line then it is working properly.
Instead of static include I have used jsp:include also.
Still I m getting same problem.
We have to migrated from JDK 1.5 to 1.6 and Tomcat 5.0.28 to 6.0.14, still same problem is there.
We have tried a lot but didnt get success to overcome this problem.
If anybody having any solution then ur each reply will be appreciated.
Thanks in advance..........!!!!!!!

Hi "mshanu" and "amit" Thanks for ur replies Here I m posting the code of "top.jsp"........!!!!

<jsp:include page="top.jsp" flush="true">
</jsp:include>
         AND
<%@ include file="top.jsp"%>but none of this worked.
If I remove the include then It is working properly.
But I need inluded file too so that I am wondoring for the solution.
This problem seems very wiered to me. I dont know why it is happening.
This problem is started only when I used the TOMCAT 6.14.
Is it the bug of TOMCAT 6.14 or What somebody Plz help.
I got stuck here.........!!!!!!!!!!
It doesn't seem any problem with top.jsp. As per my thinking the problem is there in include due to that it doesn't compile the JSP page in Tomcat 6.0.
Earlier I am having same code running on the Tomcat 5.0.28 and JDK 1.5.0.
But problem occured when I have used Tomcat 6.x...!!

Java Studio Creator and JDK

I'm trying to create a game application using java and i've downloaded both java studio creator and JDK. However i'm having problems of writing the program. Should i use notepad and compile it using JDK? Or can i simply use the java studio creator and type in my java codings? And i cant seem to type in any codings in the java studio creator.
Can someone help me please? Thank you.

Hello, Burpyjac!
I don't understand what you want to do exactly. If you would like to write an applet for a website maybe Java Studio Creator is not what you want, it's an IDE for developing web applications running in an application server like Glassfisch, SJSAS, Tomcat and the like.
If your game need animation, drawings in a panel and the like you would need another IDE like Netbeans for example to develop an applet. Of course you can just use Notepad, but a IDE like Netbeans is much more comfortable (syntax highlighting, project managment, debugging).
Java Studio Creator is an IDE for web applications and it is based on Netbeans (if you saw both you will notice). If your game can live without graphics maybe you can use it - but be aware that this applications do not run alone, you need an application server.
Cheers,
Jan

Oracle 8.1.5 and JDK 1.2 Thin Driver

We are doing some prototyping with Oracle 8.1.5, BEA WebLogic
6.1, and JDK 1.3. We needed to know what is the latest version

configuration.
Or are we the only users doing this and is it mandatory that we

Check out the SQLJ FAQ at:
http://technet.oracle.com/tech/java/sqlj_jdbc/htdocs/faq.html
"ExceptionInInitializerError: NullPointerException"
(This is likely a general configuration issue, not something specific to your code.)
If you see the following stack trace:

at sqlj.framework.ClassFileReader.attribute_info(Compiled Code) ...
at sqlj.tools.Sqlj.statusMain(Compiled Code)

then you are likely running SQLJ version 8.1.5 or earlier under JDK 1.2.x or later.
You need to download the SQLJ 8.1.6 SDK patch, which contains a new translator.zip
version that you can use to replace the translator.zip from 8.0.5/7.3.4 or from JDeveloper 3.0.

CF7 and JDK 1.4.2 - EV SSL Certificate Issue

Let me start off by telling the group that we do not use CF for any of our applications. We are a payments company that hosts a .NET API in IIS that 100's of thousands of customer use. We have one particular customer using CF7 and JDK 1.4.2 who is currently unable to process against our API. About a week ago we upgraded our SSL certificates to EV (Extended Validation) and since that time our once happy customer is now unhappy. I have spent hours working with him, going through FAQs and walk throughs, knowledge bases and forums and have had no luck. Here are the details:
EV Certificate issued by DigiCert (4096-bit).
Customer is on CF7 and JDK 1.4.2.
When he attempts to process against our API with the new certificate he gets 'Connection Failure: Status code unavailable' message from his CF application. He is using cfhttp to post his requests. We found a work around that indicated that the only issue with JDK 1.4.2 was importing the high-bit certificates. Our customer installed JDK 1.6, imported the certificate (and all intermediate certificates) successfully into the cacerts file, but when attempting to list using JDK 1.4.2 is returns an invalid certificate error and still will not work.
Please help as we are currently in a work around state for this customer (not long term) and we have exhausted the resources we have access to for solving this issue.
Thanks in advance to those gurus that reply. I have attached a sample post from our customers logs with non-essential data removed.
I can be reached by phone at 801-341-5620 if anyone feels like reaching out to talk.
- Dave

Dave,
I am having a similar issue with CF7 and PayPal's Reporting API which also uses EV SSL.
I can offer that in my testing, both CF 8 and CF 9 do seem to be able to work when using CFHTTP and EV SSL,
so the only solution I can offer at this time is to make the suggestion to your customer that they need to upgrade
to either CF 8 or CF 9 to get the issue quickly resolved.
I'm still working to see if I can find a solution for CF7 and I've been asking around in the CF community for help, so
if I do find a solution, I'll definitely post it there for you.
Cheers

Am I to assume that jdk1.4.x is no longer supported in JDeveloper and that I should start using JDK1.5.x? But apps built with JDK1.5.x are not supported in AppServer 10.1.2.0.2, which is J2EE 1.3 compliant... Does that mean that JDeveloper 11g is suitable only for apps deployed on OAS 10.1.3.x and above? (OAS 10.1.3.x is J2EE 1.4 compliant, and OAS 11g will be J2EE 5.x compliant).
Comments please.
Thx!

be on OracleAs 10.1.3 at a minimum<<The problem (for us) with Oracle AS 10.1.3 is that Portal 10.1.4 will not run on it (not certified). We want to take advantage of ADF RC and we hope to be able to produce JSF portlets or "portletized" apps. But at the moment we are "stuck" with 10.1.2.0.2 and JDK 1.4.x/J2EE1.3...
While you can have a 10.1.2 farm and add a 10.1.3 separate instance it is not a clean/complete integration (you can't manage all services from the 10.1.2 farm EM and others; this is what I've seen so far, IMO).
We can't wait for OAS 11g to come out and take a look at that. And I certainly hope that Portal will be certifed on 11g so that we can just jump there.
Another wish: WebCenter functionality in Portal, or Portal/WebCenter rolled out into one.

Difference between SUN JDK V1.4.2_05 and JDK V1.4.2_07

difference between SUN JDK V1.4.2_05 and JDK V1.4.2_07 and I want to the link in SUN for that. I want to know the bug fixes between them.

Perhaps you should look at the documentation which comes with JDK 1.4.2_08.
It has the bugs fixed listed.

Tomcat 4.0 and Apache 2.0.35

Hello,
I am trying to install mod_jk or mod_webapp.so with Tomcat 4.0 and Apache 2.0.35, running on Windows XP Professional. When I try to start Apache, it fails to see it the new module in the modules/ directory, even though it's most definitely there. Anybody have any thoughts?

The Tomcat 4 has different settings compared to the previous releases (Tomcat 3.3.x and Tomcat 3.2.x). If the previous releases use mod_jk.dll and/or mod_jk.so, the version 4 uses different modules. I have obtained the following from the server.xml file from Tomcat 4.0.3.
The MOD_WEBAPP connector is used to connect Apache 1.3 with Tomcat 4.0
as its servlet container. Please read the README.txt file coming with
the WebApp Module distribution on how to build it.
(Or check out the "jakarta-tomcat-connectors/webapp" CVS repository)
To configure the Apache side, you must ensure that you have the
"ServerName" and "Port" directives defined in "httpd.conf". Then,
lines like these to the bottom of your "httpd.conf" file:
LoadModule webapp_module libexec/mod_webapp.so
WebAppConnection warpConnection warp localhost:8008
WebAppDeploy examples warpConnection /examples/
The next time you restart Apache (after restarting Tomcat, if needed)
the connection will be established, and all applications you make
visible via "WebAppDeploy" directives can be accessed through Apache.

What's the difference between Java SE 6 Update 10 RC and JDK 6 Update 7

I want to download jdk and do some java development. But I saw "Java SE 6 Update 10 RC" and "JDK 6 Update 7" are both there for me to download. I don't know which one should I download. I used to think JDK is Java SE. Can someone explain it to me? Great thanks!

[Java 6 Update 10|http://java.sun.com/developer/technicalArticles/javase/java6u10/] provides some nice enhancements for deploying Java to the Desktop, a nice new look and feel and some other nice additions.
Also, JDK 6 Update 7 is the latest, officially released version at the moment. The Update 10 is only a release candidate (that means it is what might become the final Update 10, but can still change).
For normal development (and especially when you're just starting to learn) there shouldn't be too much difference, so choose whichever you want.

Tomcat load balancing and frames

Hello !
I am having an web applications built on Servlets and JSP, but in my application I am using frames so after I am connecting to the application I am having one JSP wtih 3 frames (JSP).For the web site I am using sessions.My application is working ok on one Tomcat, but when I tried to put the application on server where the configuration is a loadbalancing for 2 Tomcats I am having problems because frames:after I am connecting to the application I am seeing the first frame a thousand of times (like a cycle).I am using Tomcat 4.x
Can anybody help me with some ideeas?
Thank you!

First off, consider switching to Tomcat 5. The JSP performance alone is worth the switch. It is a much more robust servlet engine than Tomcat 4.
Second, your frame problem is likely due to loadbalancing directing each frame to a different server. If you like that approach, examine your method for HTTP session replication. How are sessions being replicated between Tomcat instances? (Or even are they?) If you want true perfect load balancing you'll need good session replication.
If that doesn't work you may consider a loadbalancing scheme involving server affinity, also known as "sticky sessions." That way all requests for a given session will go to the same server. With this scheme your frames will all render properly because they will be served up by the same machine.
For Tomcat clustering and loadbalancing I recommend Apache with the MOD_JK plugin for tomcat clustering, loadbalancing, and failover. MOD_JK supports both round-robin and sticky session loadbalancing.
