Classpath in JSP bussiness Componets

Hi all,
I am developing an application with Oracle Bussines Componets, but I want to use JSP for the interface. When I try to execute one of them I get the next error:
Request URI: /webapp/CpAgestionView.jsp
Exception:
java.lang.NoClassDefFoundError: oracle/jbo/html/databeans/Res
but I have the jbohtml.zip in the classpath and that packge contains that class (Res(. What happens? Any comment would be appreciated.
Thanks

Import CLASSPATH in JSP

Hi all,
I am following a guide to install an JSP application on Tomcat.
The third point is:
Confirm JAR Files are Included in CLASSPATH
Please ensure that the .jar files in the WEB-INF/lib/ directory of your web
application are included in the CLASSPATH for your application.But I don't know how to do it (I'm not an expert of JSP).
Someone can help me to add the code line(s) in a such way that I can include the WEB-INF/lib/ in the CLASSPATH of my application.
Thanks
Enrico

I've understood now. The google's code,
<td>
         <iframe name="identity_provider" src="./ProcessResponseServlet"
          width="100%" height="100%" frameborder="1"></iframe>
</td>is wrong. I've just replaced this with:
<td>
          <iframe name="identity_provider" src="./identity_provider.jsp"
          width="100%" height="100%" frameborder="1"></iframe>
      </td>But now the problem is always the same because inside this file there is:
<form name="ServiceProviderForm" action="./CreateRequestServlet" method="post">
<input type="hidden" name="action" value="Generate SAML Request">
<input type="hidden" name="returnPage" value="service_provider.jsp">
<p><center><input type="submit" value="Generate SAML Request"></center></form>
<%
      String error = (String) request.getAttribute("error");
       String authnRequest = (String) request.getAttribute("authnRequest");
      String redirectURL = (String) request.getAttribute("redirectURL");
      if (error != null) {
      %>
        <p><center><font color="red"><b><%= error %></b></font></center><p>
      <%
      } else {
        if (authnRequest != null && redirectURL != null) {
      %>
        <p><div style="padding:6px 0px;border-top:solid 1px #3366cc;border-bottom:solid 1px #3366cc"><b>Step 3: Submitting the SAML Request</b></div></p>
        <p>You can now review the generated SAML request before submitting it to the identity provider.</p>
        <p>As noted in the <b>Pre-Transaction Details</b>, when you install this application, it will send SAML authentication requests to the <b>ProcessResponseServlet</b>, which is included in the sample code package.</p>
        <b>Generated SAML XML</b><p>
        <input type="hidden" name="redirectURL" value="<%=redirectURL%>"/>
        <div class="codediv"><%=RequestUtil.htmlEncode(authnRequest)%></div>
        <p><center>
        <input type="button" value="Submit AuthnRequest"
               onclick="javascript:parent.frames['identity_provider'].location = '<%=redirectURL%>';return true;">
        </center>
     <%
     %>And there is the file "CreateRequestServlet.class" in the "WEB-INF/classes/servlets" and the web.xml maps also this file.
But when i press the button "Generate SAML Request", I have the usual error:
HTTP Status 404 - /CreateRequestServlet/CreateRequestServlet
type Status report
message /CreateRequestServlet/CreateRequestServlet
description The requested resource (/CreateRequestServlet/CreateRequestServlet) is not available.

Classpath and JSP

HI
I had a question regarding connection of JPS with Oracle8i.
I have created a jsp page (Firstpage.jsp) for connecting to the database, Oracle. (I have provided the code at the bottom).
I am using Tomcat 3.3.
Everytime I run this page , I get an error: Class OracleDriver not found. What should I do to connect to oracle?
My questions are as follows:
1) In order to connect to the database what should be the classpath set - (what i have rite now in my classpath is .;C:\Tomcat\lib\common\servlet.jar;C:\Tomcat\webapps\ROOT\WEB-INF\classes)
2) Do i Have to make any changes in the server.xml file or tomcat-modules.jar file? If so wot changes do I have to make. Or is there any other file
3) Like java where I add classes12.zip and nls_charset12.zip to the classpath while connecting tothe dbs , Do i have to do the same ? But where should the classes12.zip and nls_charset12.zip files be ? ie. should they be in C:\oracle\ora81\jdbc\lib or should they be copied to another folder ?

I hope somebody answers my queries, coz im having sleepless nights

One way is to copy classes12.zip into:
<JAVA_HOME>jre\lib\ext
and setting the classspath to point to it.
Another way is to set the classpath to the Oracle's
directory where you have the driver:
oracle\ora81\jdbc\lib
No No NO!
Tomcat does not look at your classpath. It completely ignores it.
As far as Tomcat is concerned its class path is
web-inf/classes (with .class files in it)
web-inf/lib (with .jar files in it - note it will not read .zip files)
Tomcat lib directories.
For Tomcat 3.3, go here to read all about it.

EAR and long CLASSPATH at JSP compilation time

          Hi all,
          we have an EAR-packaged application with over 260 jars (mainly
          EJB) that is deployed to a managed server WL6.1SP3(AIX). Then
          we hit a JSP page of this app. and Weblogic generates the
          adecuate .java file that is passed as an argument to a forked
          process for the javac compiler with a CLASSPATH that is more
          than 22KB!! of length because of the EAR classloader schema
          (it must include all the jars of the EJB level).
          The problem is that the EAR deployment in WL6.1 generates a fixed and very long
          path for every jar that it is composed of:
          $WL_HOME/./config/DOMAIN/applications/.wl_notdelete_EARNAME
          /wlap#####/ejbjarname.jar
          and the invoke of the compiler fails with argument too long.
          We can control the EJB jar name, EARNAME, WL_HOME
          and DOMAIN to shorten the CLASSPATH, but that is not enough
          giving that the fixed part of the PATH is very long, for example:
          with DOMAIN=DOM1, WL_HOME=W, ejbjar name=EJB1, EARNAME=EAR1
          you get:
          /w/./config/DOM1/applications/.wl_notdelete_EAR1/wlap#####/EJB1.jar: that is
          68 chars * 260 jars = more than 17KB only with the
          EJB part of the CLASSPATH (plus the standard SYSTEM CLASSPATH
          and WARS CLASSPATH.)
          As workarounds we can:
          1.- Use an "pseudo exploded" EAR with EJBREMOTE and EJBHOME in clientclasses path
          with every jar and war by their own. Not very
          clean and we've lost the benefits of EAR deployment.
          2.- Consolidate a bunch of EJB in every jar. More administrative
          tasks (common xml descriptors:ejb-jar.xml,...) and less isolation
          between developer teams.
          3.- Consolidate at functionality level (source) a bunch of EJB
          in a few one. :(
          4.- Precompile every JSP outside of WEBLOGIC and generate
          the corresponding class and entries at web.xml and weblogic.xml
          5.- ...?
          or maybe:
          6.- configure this very long directory of deployment
          to a shorter deployer choosen and use relative paths.
          Is this possible? :)
          PacoG.


You may try to use JSP compiler class. Please specify 'compilerclass'
          option in weblogic.xml. This option specifies name of a Java compiler
          that is executed in WebLogic Servers's virtual machine. (Used in place of
          an executable compiler such as javac or sj.)
          Please see
          http://e-docs.bea.com/wls/docs61/webapp/weblogic_xml.html#jsp-descriptor.

Error while accessing a jsp file

          hi all,
          i am working on weblogic5.1 under solaris platform.
          my folder hierarchy is as follows weblogic_home/classes/weblogic/sun1/sun2.
          i have an import statement as follows import sun1.sun2.* in my JSP file.
          when i access this jsp file from my browser i have an error.
          the error is import package sun1 not found.
          i have set my classpath correctly(i feel so)...
          can anybody help me with this problem.
          if there is some fault in my classpath please tell me where exactly i should set my classpath for jsp files.
          thanx in advance.
          Prasad.


          Hi,
          1) what is your "weblogic.httpd.documentRoot=????"
          2) if it is "public_html" put your jsp there.

JDeveloper 11g Using jsp to display images

I am converting a 10.1.3.3 application to 11.1.1.3
It has 2 web modules. One is an ADF administrator module and the other is a public web that displays information including images stored as blobs.
This public module has a simple technology scope, only html, java, jsp and servlets. It is a hand me down from a few technologies ago and ran well on 10.1.3.3
To display images it uses a jsp acting as a servlet which is referenced inside other jsps. Since moving to 11g the images no longer display. If I use a java class servlet it works
however I have to use the full url, e.g. http://mydomain:myport/web/Sevlet?.... which means I have to update the details for each deployment.
I can use <h:graphicImage but this means I have to include JSF and use expression language to fill in the servlet parameters.
I don't know what has changed to cause it to fail. Weblogic?
The Libraries and Classpath include
JSP Runtime
Servlet Runtime
JSTL 1.2
The servlet jsp is as follows remembering it works in 10.1.3.3

i responded to your duplicate message 4 days ago:
is it possible to insert and retrieve images from sql server using actionscript.
you'll need server-side script to query your database and you can use the flash urlloader class to call your script.
also is it possible to create a flash scrolling gallery based on images stored in a database and everytime an image is added it is displayed in the gallery.
load the data using the urlloader class and then load the images. periodically query the database for new images if there's no direct way for flash to know a new image was added.

can any one please suggest a solution .

How does performance of JSP compare to PHP, ASP, etc?

          "One thing I've found lately is that server-side Java (JSP) is,
          surprisingly, often omitted by web hosting providers. I thought that,
          Java being the ultimate web language, just about everyone would offer
          it, but it is fairly difficult to find at reasonable prices. Apparently,
          it is a relative resource hog. One guy I talked to said that they
          wouldn't be able to put more than three JSP sites on a server, whereas
          using PHP or ASP, etc, they could do an order of magnitude better."
          A friend of mine sent me that statement above. Is this roughly a true
          statement? (I'm posting this here just as a starter. It is not aimed at
          Weblogic at all...note that Weblogic is NOT even mentioned in the quote
          above.)
          The phrase "...everyone would offer it" pertains to the fact that my friend
          has been conversing with various 'web hosting providers', and he came to
          this
          'conclusion' after talking with a bunch of them in search of a company to
          host some of his client-companies web pages.
          Thanks in advance for your experiences.
          Cheers...
          Dave


On resource needs, in my experience, JSPs (and Java servers in general) require
          considerably more memory to run, but can actually reduce the CPU requirements.
          For example I had an application written in mod_perl, and when compared to the
          J2EE port, the mod_perl version consumed 1/2 the RAM, but the J2EE version
          was suprisingly much faster in execution (sluggish pages in the mod_perl version
          were very snappy in the J2EE version, on the same exact hardware.)
          But the biggest problem for ISPs is actually the management of the servers, not so
          much the hardware resources it takes. Today J2EE servers are still relatively complex
          to manage and configure. E.g., even a small ISP using Apache can easily(!) support
          dozens or even hundreds of virtual hosts for its clients... try doing that with Weblogic
          or any other JSP/Servlet/EJB engine... nightmare!!
          Take the deployment model as an example... in Perl/PHP/Frontpage-land the ISP
          can simply give each clients a few directories (e.g., the old 'cgi-bin' and 'public_html'
          dirs) and the client is self-sufficient. When a client changes something, they just ftp
          the new files into the directory and voila, it's done. No need for hand-holding from the
          ISP.
          In contrast one can't do that with J2EE servers today... applications must be packaged
          in some specific format, resources (like JDBC DataSources, JavaMail, security roles,
          etc.) must be setup often by hand, the administrator must contend with a variety of
          classpath and JSP compiler issues, the application then must be deployed to the server
          using a proprietary tool (which can fail), the server may need to be told to "reload" the
          new application, etc., etc.
          Not very easy to manage when you have lots of clients!! Not to mention that very few
          system administrators today in ISPs have a good understanding about Java in general;
          few can tell the difference between Jdk 1.0 and Jdk 1.4; and only a tiny minority will
          know something about running J2EE servers in production at all.
          regards,
          -Ade

Help with JSP pre-compiling

We have a web application using Jboss4.0.5, jdk 1.6 and And 1.6.5, and now we try to do a pre-compiling as part of our build procedure.
That is the first time I am going to do a pre-comp of a major application, which includes about 1700 jsp files.
The directory tree of the application is as follows:
/project
    |--- > /web_pre-comp/pages/jsp ( it contains all the jsp files )
    |----> /web_pre-comp/WEB-INF ( it contains the web.xml file.)
    |----> /web_pre-comp/WEB-INF/tld ( it contains the tld files)
    |----> /web_pre-comp/WEB-INF/src ( it coutains the generated src file from jsp )
    |---->/web_pre-comp/WEB-INF/classes ( it contains the compiled classes once the jsp java files are generated.   )
    |----> build.xml ( the ant script )And there is my build.xml file looks like:
<project>
      <target name="pro.jsp.generate" depens="init">
       <java classname="org.apache.jasper.JspC" fork="yes">
          <classpath refid="tomcat.jsp.classpath"/>
          <arg line=" -d "/>
          <arg value="${jsp.generated.src.dir}"/>
          <arg line="-p"/>
          <arg value="${jsp.package.name}"/>
          <arg line="-webapp"/>
          <arg value="${jsp.src.dir}"/>
       </java>
   </target>
</project>When I was running the ant script, I received such message:
[java] org.apache.jasper.JasperException: The absolute uri: http://www.prounlimited.com/wandappconfig.tld cannot be resolved in either web.xml or the jar files deployed with this application
We do have suh messages included in the web.xml file.
<taglib>

        <taglib-location>/WEB-INF/tld/wandappconfig.tld</taglib-location>
    </taglib>Any Ideas how to make it working ?
Another side questions is when some java file are created from JSP, I see some "005f" included in the java file name, such as "inc_sup_princing_view.jsp" creats a
"inc_005fsup_005fpricing_005fview_jsp.java" file. Does someone know why this happen ?
Thanks a lot !

We have a web application using Jboss4.0.5, jdk 1.6
and And 1.6.5, and now we try to do a pre-compiling
as part of our build procedure. Hi Charlie,
According to your ant build script you're using Jasper compiler, but your web container is JBoss.
I know that Tomcat uses the Jasper compiler --- but I don't know if JBoss supports Jasper or not. Please check with JBoss if they support Jasper, if not they my support a different pre-compiler.
That is the first time I am going to do a pre-comp of
a major application, which includes about 1700 jsp
files.
The directory tree of the application is as follows:
/project
|--- > /web_pre-comp/pages/jsp ( it contains all
the jsp files )
|----> /web_pre-comp/WEB-INF ( it contains the
web.xml file.)
|----> /web_pre-comp/WEB-INF/tld ( it contains
the tld files)
|----> /web_pre-comp/WEB-INF/src ( it coutains the
generated src file from jsp )
|---->/web_pre-comp/WEB-INF/classes ( it contains
the compiled classes once the jsp java files are
generated.   )
|----> build.xml ( the ant script )And there is my build.xml file looks like:
<project>
<target name="pro.jsp.generate" depens="init">
<java classname="org.apache.jasper.JspC"
fork="yes">
<classpath refid="tomcat.jsp.classpath"/>
<arg line=" -d "/>
<arg value="${jsp.generated.src.dir}"/>
<arg line="-p"/>
<arg value="${jsp.package.name}"/>
<arg line="-webapp"/>
<arg value="${jsp.src.dir}"/>
java>
</target>
</project>When I was running the ant script, I received such
message:
[java] org.apache.jasper.JasperException: The
absolute uri:
http://www.prounlimited.com/wandappconfig.tld cannot
be resolved in either web.xml or the jar files
deployed with this application
Check if the tld folder is visible to the classpath tomcat.jsp.classpath used inside the Ant build file.

Another side questions is when some java file are
created from JSP, I see some "005f" included in the
java file name, such as "inc_sup_princing_view.jsp"
creats a
"inc_005fsup_005fpricing_005fview_jsp.java" file.
Does someone know why this happen ?
The 005f is expected, it is for internal reference for the pre-compiler, nothing to worry about.

Fix many web access problems with IFS 9.0.1 on Solaris (and other OS's)...

When the installation is done according to the documentation,
web access does not work because the scripts that add entries to
the jserv.properties file add duplicate references to
wrapper.env and wrapper.classpath. Look at the jserv.properties
file below and look at the remarked-out (#) lines of the
duplicate references. For example, look at the references to the
wrapper.env=LD_LIBRARY_PATH
Oracle, please note this bug so the web access problems are
minimized when the product is intstalled.
Thank you,
William T.

# General parameters
# Set the default IP address or hostname Apache JServ binds (or

# If you have a machine with multiple IP addresses, this address
# will be the one used. If you set the value to localhost, it
# will be resolved to the IP address configured for the locahost
# on your system (generally this is 127.0.0.1). This feature is
so
# that one can have multiple instances of Apache JServ listening
on
# the same port number, but different IP addresses on the same
machine.
# Use bindaddress=* only if you know exactly what you are doing
here,
# as it could let JServ wide open to the internet.
# You must understand that JServ has to answer only to Apache,
and should not
# be reachable by nobody but mod_jserv. So localhost is usually a
# good option. The second best choice would be an internal
network address
# (protected by a firewall) if JServ is running on another
machine than Apache.
# Ask your network admin.

# Enable/disable Apache JServ logging.
# WARNING: logging is a very expensive operation in terms of
performance. You
# should reduced the generated log to a minumum or even disable
it if fast
# execution is an issue. Note that if all log channels (see
below) are
# enabled, the log may become really big since each servlet
request may
# generate many Kb of log. Some log channels are mainly for
debugging
# purposes and should be disabled in a production environment.

# Default: true
log=true
# Set the name of the trace/log file. To avoid possible
confusion about
# the location of this file, an absolute pathname is recommended.
# This log file is different than the log file that is in the
# jserv.conf file. This is the log file for the Java portion of
Apache
# JServ.
# On Unix, this file must have write permissions by the owner of
the JVM
# process. In other words, if you are running Apache JServ in
manual mode
# and Apache is running as user nobody, then the file must have
its
# permissions set so that that user can write to it.
# Syntax: log.file=[log path and filename] (String)
# Default: NONE
# Note: if the file could not be opened, try using absolute
paths.
log.file=/d3/Apache/Jserv/logs/jserv.log

log.dateFormat=[dd/MM/yyyy HH:mm:ss:SSS zz]
# Since all the messages logged are processed by a thread
running with
# minimum priority, it's of vital importance that this thread
gets a chance
# to run once in a while. If it doesn't, the log queue overflow
occurs,
# usually resulting in the OutOfMemoryError.
# To prevent this from happening, two parameters are used:
log.queue.maxage
# and log.queue.maxsize. The former defines the maximum time for
the logged
# message to stay in the queue, the latter defines maximum
number of
# messages in the queue.
# If one of those conditions becomes true (age > maxage || size
maxsize),# the log message stating that fact is generated and the log
queue is
# flushed in the separate thread.
# If you ever see such a message, either your system doesn't
live up to its
# expectations or you have a runaway loop (probably, but not
necessarily,
# generating a lot of log messages).

'''''Firefox Options > General > Homepage'''''.
Press the button labeled ''''Use Current'''.'
=====================================
Open a new window or tab. In the address bar, type '''''about:config'''''.
If a warning screen comes up, press the '''''Be Careful''''' button.
This is where Firefox finds information it needs to run.
At the top of the screen is a search bar. Enter '''''browser.newtab.url'''''
and press enter. '''''browser.newtab.url'''''
tells Firefox what to show when a new tab is opened.
If you want, right click and select '''''Modify'''''. You can change the
setting to;<BR><BR>about:home (Firefox default home page),<BR>

about:blank (a blank page),<BR>
or you can enter any web page you want.<BR><BR>
The same instructions are used for the new window setting, listed as
'''''browser.startup.homepage'''''.

Classes not picked up from WEB-INF/classes

9ias R2: OC4j
Some classes could be found from WEB-INF/classes by JSP pages but some others could not.
WEB-INF/classes is part of the classpath in JSP's point of
view.
And if explicitly import the class such as
import abc;
in JSP pages and the class could be found.
Anybody has any idea? Or anything wrong I am doing?
Thanks!

CLASSPATH problem, deploying JSP app without right to modify classpath...

I want to deploy a JSP web app to apache server with JRun for running JSP, but I don't have the permission to copy the required library files to the classpath, nor modify the classpath to append my application's path. Is there any way to workaround? Thank you

Well, thanks for the tip. The answer is yes and no. Yes, the jar is in my classpath, but no the lib directory containing the jar is not included in the dist directory when I clean and build the project. This only happens when I include either the JavaHelp jars or just the jh.jar (which should be all I need) in the classpath. When I read the manifest file, it's clearly looking for /lib/jh.jar, but the directory does not get created on build (whereas, the lib directory is there if the JH jars are not included).
Makes no sense to me. Any idea as to what's happening here? The help system works great in the IDE.
Thanks for your help.

How to set the classpath and path from the jsp to call java class function

Hi Exprets,
I have a requirement to call a java class function which returns a hashmap object from the jsp. The java class in present in one jar file and that jar file is location somewhere in unix path. So the requirement is to set the classpath for that jar file and then create the object of the java class and then call the function.
If any one know how to achieve it, please reply as soon as possible.
thanks in advance,

It is never advisable to store large data sets in the session. But it will depend on a lot of factors:
1. How costly is the query retrieving the data from the database?
If it's a complex query with lots of joins and stuff, then it will be better to store it in the session as processing the query each time will take a lot of time and will decrease performance. On the other hand if the query is simple then it's advisable not to store it in the session, and fetch it each time.
2. Are there chances for the data to become stale within a session?
In this case storing the data is session will mean holding the stale data till the user session lasts which is not right.
3. How many data sets does the session already holds?
If there are large no. of data sets already present in the session, then it's strictly not advisable to store the data in the session.
4. Does the server employ some kind of caching mechanism?
Using session cache can definitely improve performance.
You will have to figure out, what is the best way analyzing all the factors and which would be best in the situation. As per my knowledge, session is the only place where session specific data can be stored.
Also, another thing, if the data set retrieved is some kind of data to be displayed in reports, then it would be better to use a pagination query, which will retrieve only the specific no. of rows at a time. A navigation provided in the UI will retrieve the next/previous data set to display.
Thanks,
Shakti

Where to set the classpath for custom classes in jsp

Hi,
we have created our custom classes in and ported in contentDB and that classes are internally using some jar files. Previously we have set the classpath of all the jar files provided in CDB devkit in the orion-web.xml but if are opening the explorer.jsp or any other jspx of contentDB we are getting the classcastexception and page is not opening.
Is there any problem in setting the classpath. Please if any one knows abt this, reply as soon as possible.
thanks,

I think it is Oracle 10g Release 2... since when I click the top OAS link in the Enterprise Manager Console, it took me to 'Enterprise Manager 10g Grid Control Release 2' this page.
And...10g Application Server Control Release 10.1.2.0.1, I think 2.0.1 means Release 2.
Thanks and let me know if you need something else.
