JSP problem with ANT

Hello!
I built up a web site and I want to test them using ANT. It works fine with other web page, however it doesn't work with web pages with "session" statement. For example in login.jsp I have the following statement
session.setAttribute("user", request.getParameter("userName"));
And if the user's name and password are correct, the user is directed to home.jsp, where i have the following statement to retrieve the user's name:
String id=session.getAttribute("user").toString();
In order to test the above 2 pages with ANT, I have the following code in builder.xml:
<?xml version='1.0'?>
<project name="proj" default="test" basedir=".">
<target name="test">
<get src="http://path/login.jsp?userName=id&passWord=1111" dest="1.html" />
</target>
</project>
When I run the script, I get the error that the home.jsp cannot be opened (see below)
[get] Error opening connection java.io.IOException: Server returned HTTP response code: 500 for URL: http://path/home.jsp
I am pretty sure the above error is caused by the "session" statement, because if I remove the statement in home.jsp, the page can be correctly opened. But I really need the "session" statement, Can someone tell me how to deal with it?
thanks a million.

Usually with a 500 error there's more detail in a server log somewhere. Can you find anything in stderr.log or some such?

One mistake i find in your code is while retreiving the session value its session.getAttribute("userName"), as you stored the value using the parameter 'userName'. Is it not causing problem. Please check...

Xml/html to jsp - problem with quotes in attribute values

I am trying to convert a static html document into a jsp using an xsl stylesheet, but run into problems trying to use the jsp expression syntax inside of attribute values.
Here is a sample of the source file:
<input type="text" name="firstName" value=""/>
Here is what I want the resulting jsp file to look like:
<input type="text" name="firstName" value="<jsp:expression>customer.getField("firstName") </jsp:expression>">
Here is what part of my stylesheet looks like:
<xsl:template match="input">
<xsl:copy>
<xsl:copy-of select="@type"/>
<xsl:copy-of select="@name"/>
<xsl:attribute name="value">
<xsl:text disable-output-escaping="yes"><jsp:expression></xsl:text>
<xsl:text disable-output-escaping="yes">customer.getField(</xsl:text>
<xsl:text disable-output-escaping="yes">"</xsl:text>
<xsl:value-of select="@name"/> ")
<xsl:text disable-output-escaping="yes">")</xsl:text>
<xsl:text disable-output-escaping="yes"></jsp:expression></xsl:text>
</xsl:attribute>
</xsl:copy>
</xsl:template>
The problem i have is with the <%= customer.getField("firstName") %>. I have tried several different ways of inserting the double quotes around firstName, but no matter what I try, it always uses the entity reference instead of actually putting the " character. The jsp container will not accept the entity.
I am assuming that the problem is with trying to place double quotes inside of an attribute value. Any ideas how to get around this?
Thanks
David

Which App Server are you using?
You should just be able to escape the double quotes.
If that doesn't work, it's a bug in the app-server.
Alternatively, you can use single quotes around the
attribute value.
Hope that helps,
AlexSorry, I'm an idiot. By escaping you meant the unicode character escape "\u0022". I had not tried that. However, once i realized what you meant, I tried it, and it worked. Thanks for your help.

Paper Layout in Report JSP - problem with anchors

Hi,
I am using an anchor to connect two frames. The frames are vertically expandable and horizontally fixed. When I run the report (PDF) as an rdf, I receive no errors, however when running the same report as a JSP, I get the following error : 'Object can never fit in within....<frame-name>'.
What could be the reason? Is it a bug?
Thanks,
Bharat

hi,
i've not heared about this particular issue, but i think it might be a good idea to open a tar with oracle support. it could be, that some properties get mixed up in your particular case when saving the report as JSP and therefore the RDF works and the JSP doesn't. it is certainly not a generic issue, otherwise we would have already heared about it.
another idea would be to apply the latest patchset (9.0.2.2) that contains a lot of fixes and it might fix your problem as well.

Servlet/JSP problems with WL 4.51

Hi all
          I have a set of Servlets and JSPs running on NewAtlanta's ServletExec
          servlet engine. I am currently porting them to WebLogic. I am facing a
          few problems. I do not want to change any of my HTML/JSP/Java files
          immediately. I want the same files to work in WL as it is. Pl help.
          1. The servlets in ServletExec used to be invoked as
          http://host/servlet/servletName. But in weblogic they are invoked
          as http://host/servletName. I tried registering the servlet names
          in weblogic.properties as
          weblogic.httpd.register.servlet/XServlet=com.foo.XServlet
          weblogic.httpd.initArgs.servlet/XServlet=param=value
          Now I can call this servlet as http://host/servlet/XServlet and so
          I dont have to change any html/JSP files. Will this cause any
          problems in the future?
          2. Since we used to run ServletExec on IIS, we created a virtual
          directory called /jsp in IIS under which we had all the html and
          JSP files. Our servlets will get the http requests, get data from
          database, put the results in session/request variables and dispatch
          it to appropriate JSP page. So, all our servlet code looks like
          this:
          RequestDispatcher dispatcher =
          getServletContext().getRequestDispatcher("/jsp/test.jsp");
          dispatcher.forward(request, response);
          How do I make this code work with WebLogic? Is there any way to
          create virtual directory and make it work like in IIS?
          Thanks for any help.

You might try
          weblogic.httpd.register.jsp/*.jsp=weblogic.servlet.JSPServlet
          but a better/ easier way would be to just move all of your jsp files to a 'jsp'
          subdirectory beneath public_html

JSP problems with NetBeans 4.1

Hi Guys,
I have the following problem. I am working with NB 4,1, and trying to import a Enterprise application with existing sources. This is the sample application in the tutorial for importing.
So I have done everything exactly as it says, and when I run the project, everything is fine, deploying and so on. The structure of the web module is so that, there is one index.html file, and after that it "leads" to a couple of JSP clients. The browser opens "http://localhost:8080/cmpcustomer-war", and when you click on one of the links, and exception is displayed which says that the file
"http://localhost:8080/customer/createCustomer.jsp" does not exist.
When I look in the project tree in NB, under the web module the jsp file exists, under WebPages dir. I click on properties on the web module, and there on the run tab??, and the "context path" is set to "customer", I don't know it must be working, I don't know wy it is not.
Thanks in advance.

every time i open the ide it generates an IO Exception and it dosen't recognise the midp classes.
i created a new user account and ran the ide from there and it opened without generating the IOException and it showed me the classes and everything, it ran beautifully. now when i closed the program and later reopened it, it generated the IOException and dosen't recognise the classes anymore.

Problem with Ant Script while deploying a BPEL Process

Hi all,
Im making use of Ant script to Deploy a BPEL process ...the bpel process simply invokes the credit rating service and returns the credit rating..credit rating service and the whole BPEL
process are deployed in the default domain...now i made a new domain and making using of Ant scripts to deploy it to this Domain in the same local server ...i followed the steps
from this blog http://blogs.oracle.com/rammenon/2007/07/deploying_bpel_process_to_mult.html now my problem is even though i mention a different Domain Name in
ant- orabpel_dev.properties its always getting deployed to Default domain........can anyone Plzzz help me.
Edited by: 0racler on Aug 15, 2009 12:09 PM

in build.properties of the project -
uncomment (remove the #) and change to the new domain
# Change below if deploying in domain other than "default"
#domain = default
when you run deployProcess target - you should see which domain is used - based on the above variable.
cheers

Could any one please tell me what should I do? The server runs well in the "localhost:8080..." I have no clue what I should do...

The problem might be that one of the jar files containing the java.rmi.* files musst be missing or perhapz, the path to these jars in the build.properties must be given wrong. CHk them there might be spelling mistake in build.properties in comman directory as jaxp.holme=${jwsdp.home}/jaxp-1.2.2 where holme must be home,
or some other mistake.
..........or if u have been un/installing too much of javastuffs try cleaning the whole Java from yr system and reinstall them that actually helped me once..................
............or chk yr HelloClient Program if its not what the tutorial provides

Swing Applet in JSP: problem with fetching data from database

<jsp:plugin type="applet" code="NewJApplet.class" codebase="applets"

<jsp:fallback>Could not load applet...</jsp:fallback>
</jsp:plugin>
if i view it in using AppletViewer it runs perfectly and display the data in JLabel. (ie, both jlblTitle and jlblNewTitle).(ie, DATA FETCHES FROM db AND DISPLAYS PROPERLY)
BUT IF I CLICK ON INDEX.JSP, ONLY jlblTitle APPEARS. jlblnNewTitle WILL BE BLANK(this label name is supposed to fetch from database)
EVERY THING IS DISPAYING PROPERLY EXCEPT DATA FROM DATABASE!!!
i signed the applet as follows :

Problems with Ant when using JDK1.4

Hi,
I am currently trying to convince JDeveloper (9.0.3.10.35) to use jdk1.4 for building and executing my project.
Now, using the IDE for building and execution everything seems to work fine after switching to the new J2SE Version in the project settings.
Ant, however, refuses to work with the new IDE. It gives an "Error: Unable to execute Ant"
On the other hand, staying with the default JDK version 1.3.1_02 (coming with JDeveloper) for ant execution results in conflicts of newer class versions (i.e. org.w3c.dom.Node) w.r.t. to <jdev>/lib/xmlparserv2.jar. The error is:
compile:
[javac] Compiling 263 source files to C:\Daten\JDeveloper\Projects\IAS39\jdev\classes
[javac] C:\Daten\JDeveloper\Projects\IAS39\src\hea\accounting\cmd\AbstractCommand.java:20: cannot access org.w3c.dom.Node

[javac] Please remove or make sure it appears in the correct subdirectory of the classpath.
[javac] protected void readKey(Node keyNode){

Obviously, I am missing something! Any help is highly appreciated!

I experienced something similar. I tried to use JDK 1.4.2, I compile the project without errors but, when I try to run the project, which has EJBs, it fails.
If I do the same using JDK 1.3.1.x, it works fine; but I need 1.4.x.
The messages are the following:

Problems with ant

Hi,
I'm trying to add a component to the Java Pet Store and when ant tries to compile ShoppingClientFacade where I plugged in my component I get an error saying the package where my component is in, does not exist... Am I missing something in a build file? where do I specify where my component can be found?
thanks alot

Thanks for your reply,
<snip>
>
This is strange because there are other import
statements to other pet store components, which are
found flawlessly. my bean-package is located in the
components directory, just like all other components.
There must be somekind of build.xml-file inside the
apps\petstore directory where I have to specify
exactly where my component can be found. But I just
don't know where. :-(
This should not be true if you placed it, as I understand, at the same location as the other packages...
Ant knows the location - otherwise it would not find the others...
I will have a look at the build.xml, but can you recheck the package definition in your own java file?
Maybe there's a problem....

Problems with ant auto-loading the base Oracle Weblogic Libraries

I'm trying to perform an ant build of a Portal Project, and I get errors trying to compile the files from classes that are part of the Oracle WebLogic Portal Server and WebLogic System Libraries. I've tried adding the two list of jars as pathelements in an ant classpath object, but the javac isn't picking up the jars properly. I feel like there should be a script or be able to call a preconfigured version of ant for this.
I'm using an external version of ant, but using the jdk160_05 from WebLogic.
In the javac I get initial errors of things like:
[javac] /vobs/.../Portal/src/Controller.java:1: package javax.servlet.http does not exist
[javac] import javax.servlet.http.HttpSession;
[javac] ^
[javac] /vobs/.../Portal/src/Controller.java:2: package org.apache.beehive.netui.pageflow does not exist
[javac] import org.apache.beehive.netui.pageflow.PageFlowController;

not very likely. run ant with the verbose and debug flags and see what gets printed out for classpath etc (these classes are in server/lib/api.jar i think) , no special characters in your paths right?

Wlcompile - nested javac elements not working with ant 1.6.1

Hi
I have a problem with Ant 1.6.1 and wlcompile.
I get the following error: The <wlcompile> type doesn’t support the nested “javac”
element.
Heres the error msg I get in debug mode:
BUILD FAILED

I’m using windows 2000. I’ve tried with weblogic.jar from Weblogic Server 8.1
SP1 and SP2. I’ve tried with JDK 1.4.1_02 and 1.4.2_04. If I’m using Ant 1.5.3
then everything works perfectly.
I’ve tried to remove the WLS included Ant version to avoid conflicts with Ant
1.6.1 and Ant 1.5.3 (that comes with Weblogic server). I’ve tried to uninstall
Weblogic Server and just keep weblogic.jar, but I still get the same error. I’ve
tried to put weblogic.jar on the classpath, still not working. I’ve tried to remove
all jar files from $ANT_HOME/lib except those jar files needed to run my test
project - ant.jar and ant-launcher.jar, but still doesn’t work. If I change $ANT_HOME
to Ant 1.5.3 and run Ant 1.5.3 then everything works. So it seems to have something
to do with Ant 1.6.1.
Here’s my example code:
<project name="wlcompile_test" default="test" basedir=".">
     <target name="test" depends="init">
<wlcompile srcdir="${src.dir}" destdir="${build.dir}">
<javac debug="${build.debuginfo}" debuglevel="${build.debuglevel}"
nowarn="${build.nowarn}" deprecation="${build.deprecated}" source="${build.source.version}"/>
</wlcompile>
     </target>
<target name="clean" depends="init">
<delete dir="${build.dir}"/>
</target>
<target name="init">
<taskdef name="wlcompile" classname="weblogic.ant.taskdefs.build.WLCompileTask"
classpath="C:\P2Development\weblogic.jar"/>
<property name="src.dir" value="src"/>
<property name="build.dir" value="classes"/>
<property name="build.compiler" value="modern"/>
<property name="build.compiler.pedantic" value="true"/>
<property name="build.debuginfo" value="true"/>
<property name="build.debuglevel" value="lines,vars,source"/>
<property name="build.deprecated" value="false"/>
<property name="build.nowarn" value="off"/>
<property name="build.source.version" value="1.4"/>
<mkdir dir="${build.dir}"/>
</target>
</project>
And I try to run “ant test”
It doesn’t work with Ant 1.6.1 and weblogic.jar from WLS 8.1 SP1 and SP2. But
it works perfectly if I change to Ant 1.5.3.

Yes, this one is fixed in 8.1 SP3. If you need a patch before then,
contact [email protected] and reference CR136493.
