Eclipse JSP .war package

Hi,
I have developed a JSP app, which uses a couple of external jars. While developing this app, I simply copied the external jars into the shared/lib directory of Tomcat.
Now I want to package and distribute this app as a .war file, as Eclipse has an easy utility for creating the .war file.
Is there an way of including the external jar files with my .war package, or do i have to tell each user to copy the external jars into the shared/lib directory of Tomcat???
Thanks in advance,
Aidan

U need MyEclipse plugin for eclipse for J2EE projects which is available at
http://www.myeclipseide.com/
You can create a war file aswell using ANT build scripts...I dont have that at the moment

Replacing class file instead of redeploying whole WAR package

Hi,
This may sound very silly question, but I thought to post it just as to confirm.
I have an application deployed in websphere ver 5. Usually when there are any changes to any class files, we rebuild the entire package, and then redeploy it using the admin console.
Now, this time I've got only a couple of classes modified...my question is that can I just replace the modified classes directly instead of rebuilding the entire package and redeploying it?
I'd assume that this is different from hot deployment, as I am prepared to start the server again if needed be. Please advise folks.
Thanks

The problem is that this particular class (servlet) can run only in production environment...there is no test environment to run it..but thanks...I did see IBM's take on this.
http://publib.boulder.ibm.com/infocenter/wasinfo/v5r0/index.jsp?topic=/com.ibm.websphere.zseries.doc/info/zseries/ae/trun_app_hotupgrade_war.html
I think it does answer the question, I can replace the .class file directly in the expanded version of the war package, and then restart the application. It should be picked up automatically.
Thanks for your response.

Jdeveloper 9.0.3 support for a standard WAR / package issues

We are being pitched on how wonderful the JDeveloper IDE is and how our days will be enlightened by it (the same folks that sold our company on o-apps 11i)... so I've been tryin' it out only to hit a MAJOR roadblock.
Basically, we need CVS development across IDE's... which shouldn't be a problem if the non-proprietary stuff all works as planned. I've used forte' in the past with success.
I am new to the JDeveloper environment. I have used Forte' before and the Sun J2EE dev. kit for deploying WARs and EAR's.. Using the tutorials provided by Sun, I found NO easy way to develop against the directory structure provided. I would also like to have ant build scripts exist in my project.. and the ability to define a source directory '/WEB-INF/src' which is my source package root, that builds to /WEB-INF/classes. NONE of this seems to be part of the 'web tier' in JDev. I've scoured the help even for the keyword 'package', and it has proven useless. And how do I specify package/folder structure in the workspace? It seems that JDev is so catered to Oracle and uneducated users that the 'more advanced' features.. (such as Java PACKAGE management.. (been there for awhile now :-} )) should be an essential feature. Help somebody!!!!
PS... my ideal experience is:
Me: Hi, Jdeveloper.. i want a project that will contain some WAR and/or ear development.
JDev: Okay, where would you like the dev. root to go?
Me: How about here, where I've already got something started (written per J2EE spec)
JDev: Okay... hmm .looks like a WEB-INF folder exists with a web.xml IN it... do you want me to recognize it as a web app?
me: sure
Jdev: I see stuff in classes... shall i maintain them as servlets?... Oh by the way,,, i see your folders and package structure.
you get the idea.
what happened to WEB-INF?... any WAR packaging?.. not oo impressed yet.

Yes, I examined the attribute settings and manually adjusted them in the entities and views. They are now updateable. Using Jdeveloper with SAPDB would be very tedious. Jdeveloper did not recognize foreign key constrains, primary keys, nor that attributes were updateable.
Is there a way to include SAPDB in the testing? It is trivial to install and run and would make Jdeveloper a more robust tool. I do not like Jbuilder's approach to master-detail client screens and would recommend using Jdeveloper for this type of work if it could handle more databases like SapDb.

Unable to compile class for JSP.       package not found

Hello folks,
I was trying to build a simple web application using Eclipse IDE, tomcat 5.x server and ant to build and deploy the application.
I referenced the following tutorial:
http://www.onjava.com/pub/a/onjava/2003/01/08/tomcat4.html
I was able to create a war file, deploy it in tomcat. When i invoke a simple jsp it works fine. However if I try to import any source pkg into jsp it throws error. Below is stack trace.

do you know what url is being looked up? the message is complaining that the url is starting with the string "an]", which seems pretty bogus.

JSP & User Package

Hi guys, I've a problem using a package built by me in a jsp file...
I've copied the jar file pack.jar in the WEB-INF\lib dir, and when I try to import the file with <%@ page import="pack.db.*" %> it don't give to me any error, but if I write: ServerMySql server = new ServerMySql(url, db_name, user, pass); t give to me this error:
An error occurred at line: 3 in the jsp file: /login.jsp
Generated servlet error:
ServerMySql cannot be resolved (or is not a valid type) for the field login_jsp.server
An error occurred at line: 3 in the jsp file: /login.jsp
Generated servlet error:
ServerMySql cannot be resolved or is not a typeWhat can I do?

You have a class pack.db.ServerMySql (exact spelling)
It is bundled in your file pack.jar, in an appropriate folder within the zip file?
ie if you expand the zip file it produces the structure pack/db/ServerMySql.classYes
Also do you have the MySQL driver in the web-inf/lib directory?I don't think that it could make my application not to work, but I've done it too
You did restart your app server after deploying the jar file into the lib directory?Yes, I've tryed to restart my computer too...

Jboss ide jboss eclipse jsp compile problem

Hi i downlaoded eclipse with jboss ide plugin for jsp support.
now configuration is jboos server + eclipse + jboss ide but i am not able to cmpile jsp pages.even though jboss server is running on eclipse no problem in that.
thanxs in advance

Do I have to use JBoss with Tomcat or am I missing
something at configuration?You're missing something. I'll bet the problem's in your JSP file, not JBoss/Jetty - unless you've dorked with the default settings and done something to make it not work. And you don't need the j2ee12.jar in your CLASSPATH - it's already there, otherwise JBoss/Jetty wouldn't run.

Looking for Eclipse/JSP tutorial

Anyone know of any good web tutorial on JSP/Servlets using Eclipse? This will save me from asking a ton of simple questions. In my initial google search I did not find anything all that good.
TIA!

Install java jdk, install tomcat, search for 'Eclipse Europa', download and configure it to use the jdk and tomcat per its instructions (its on the same web site somewhere).
Then create a new tomcat project (its in the Eclipse menu). After reading a book on JSP, get a JSP page to display in a brower by launching tomcat via the eclipse menu. Then get a servlet to work. That's the rough procedure to get you started.Zombie antics aside, why would a JDK be necessary if he's using Eclipse? It only needs a runtime

What is wrong ?
I have Windows NT and Tomcat 5 (from jwsdp 1.2).
Thank you,
Alex.

I just tried to reproduce the problem with old version of Tomcat (4.0.2) and ... it works. It is definitely specific for Tomcat 5 (or may be one of the late Tomcat 4 as well). There is another related difference:
With Tomcat 4 I could create javabean in class subdirectory (default package) and use
<%@ page import="ex01" %>
Now with Tomcat 5 I have syntax error in this line.
This syntax error disappeared when I moved javabean into package pack01.

How to set Tomcat's JSP compilation package

Is it possible to configure what root package name Tomcat uses when creating .java files from JSPs? I've searched Google, this forum, and the Tomcat JSP documentation (http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jasper-howto.html) and cannot find any indication that it is. I found the description of all the JSP compiler servlet options, both in web.xml and on the Jakarta site, but it doesn't list any option for this. I know it's possible with Ant's JSPC task, so it's tempting to think the same can be done with Jasper, but maybe not.

You're running Jasper by running "jspc.bat" (or "jspc.sh") from Tomcat's bin directory, yes?
If so, it's
jspc.bar -p <package> ...
Usage: jspc <options> [--] <jsp files>
where jsp files is any number of:
    <file>         A file to be parsed as a jsp page
    -webapp <dir> A directory containing a web-app, all jsp pages
                   will recursivly be parsed
where options include:
    -q          Quite mode (same as -v0)
    -v[#]       Verbose mode (optional number is level, default is 2)
    -d <dir>    Output Directory
    -dd <dir>   Literal Output Directory. (package dirs will not be made)
    -l          Outputs the name of the JSP page upon failure
    -s          Outputs the name of the JSP page upon success
    -p <name>   Name of target package
    -c <name>   Name of target class name
                (only applies to first JSP page)
    -mapped     Generate separate write() calls for each HTML line in the JSP
    -die[#]     Generate an error return code (#) on fatal errors.
                If the number is absent or unparsable it defaults to 1.
    -uribase <dir> The uri directory compilations shoule be relative to
                    (Default is "/")
    -uriroot <dir> The root directory that uri files should be resolved
                    against, (Default is the directory jspc is invoked from)
    -webinc <file> Creates partial servlet mapings for the -webapp option
    -webxml <file> Creates a complete web.xml when using the -webapp option.
    -ieplugin <clsid> Java Plugin classid for Internet Explorer
    -sax2 <driverclassname> Driver class name for the SAX 2.0 parser to be used

How to set up multiple log4j configurations for multiple WAR packages?

hi all,
the EAR that i am trying to deploy has multiple WARs.
I need to configure separate loggers for each these WARs.
Could any of experts can help me out.

Hi
Depending on your needs, you may find that Set level offers the best approach:
Within a Set you have the Playbacks (Set Level, so they work for the entire set) with individual patches in the set "live" for the EWI etc as needed.
You need only map one set of controls for all the Playbacks since only 1 set can run at a time.

EAR / WAR Packaging

Dear Expert,
Do you know whether there is any guildline for packing EAR/WAR according to the J2EE standard?
For example, whether
several projects should be packed into the same EAR/WAR in order to reduce the overhead of starting up the applications (ie, one EAR containning several WAR of different projects), or
each project should be packed in a standalone EAR and WAR (ie, one EAR containing one WAR for a single project), or
all projects should be packed in the same EAR/WAR (ie, one EAR containing one WAR for multiple projects)
Many thanks.

Package not found when importing in JSP

          I'm now using Weblogic 6.0 SP 2 for development. I did a test application, containing
          EJBs, and a JSP. Package the applications to an EAR file. Then I deploy the test
          application using hot-deploy - just drop the EAR into the domain\application folder.
          When I call the JSP page, I get an error saying that the package I'm importing
          is not found. What is wrong?? The test application works on Weblogic 5.1
          My WAR file contains only the JSP and XML descriptor. Do I need to include classes
          inside??? Don't think that is correct.
          Please advise.


          It was a bad mistake. Made an error in the application.xml, which refer to an invalid
          JAR file. Made the correction and it works like magic.
          Thanks :)

JSP compile for WARs...

Hi
If I wanted to precompile my JSPs and package them into a WAR where would I put them???
Under WEB-INF/generated/jsp???? Will this work regardless of the app server vendor?
I tried to look through the JSP spec to find some info on this but couldn't find any (or I may have missed it)
Is precompiling JSPs and packaging them into a WAR considered a good practice?
Thanks
Z

Well my reasoning was that /WEB-INF/classes is packaged.....and when JSPs are compiled they are compiled into a servlet (if I am not mistaken) which is just another Java class....So it should be vendor neutral...
On Sun's App Server you can choose precompile at deployment time, but I was wondering if there is a more direct approach...
I don't think precomilation works like that. Imagine
compiling jsps for tomcat, and trying to run them in
websphere.
As far as I know precompilation is done by calling the
jsp with a request parameter called
jsp_precompile and a value of true.
