Problem while compiling JSP in FORTE

Hello Friends,
I am using Fore for Java 4 Community Edition, I have created a web module. I am using internal tomcat 4.0 server. When I request for a JSP which has a bean or a class file stored in the WEB-INF\classes folder either using useBean tag or if try to create an object of that class, I get compilation error as forte is not including those classes in its classpath. But when I deploy the same application on external tomcat, it works fine. Even after I mount the classes folder in the project, it doesn't solve the purpose. Please help me to get rid of this problem. My directory structure is as follows.
root - jsp and html files
root\WEB-INF\web.xml
root\WEB-INF\classes - all class files
root\WEB-INF\lib - lib jars

I am also working on Forte. Forte has an inbuilt Tomcat. You dont need to copy any files to any where in the file mount system. You need to specify the External / Internal Browser settings, So that when you try to execute it, the .jsp file can be displayed in the browser. I havent faced any problem as you said.

Running out of space while compiling JSPs

Using WL7.0 on JDK1.3.1_06 on Solaris 8 we've run into an exception
java.io.IOException: Not enough space(see below for full stack trace)
while compiling JSPs. The problem is that we are running out of RAM
because our WL7 process is quite large and when it tries to compile a
JSP it forks itself which creates another large process. On our test
machines since there might be several running instances of WL this can
lead to the problem below. The natural fix for this would be to (1)
precompile all the JSPS, (2) increase the RAM on the machine(s) in
question, or (3) somehow force weblogic not to fork when doing page
compilations.
(1) In production we precompile our pages by running the weblogic.jspc
class using arguments like -k -compileAll -depend -webapp $BRAND -d
$DEST.
Unfortunately this doesn't compile all of the pages probably because
it doesn't execute cleanly due to the fact that we have some includes
that aren't proper stand-alone JSPS (I don't know how to fix this
other than changing all of our includes to dynamic includes which is
undesirable at runtime). Any ideas here?
(2) increasing the RAM isn't practical for all places where this
problem occurs, in some cases we have maxed out the RAM on the
machines we have.
(3) Does anyone know if it is possible to tell WL not to fork when
doing a JSP page compilation?

p.s. I did some searching on the forums before I posted this and was
surprised that most of the posts on this subject were a) very old and
b) didn't come to the conclusion that it was RAM space that the
exception is referring to.

As far as I remember, this error refers to the lack of swap space to
fork the new process.
In theory, you can specify compilerclass in weblogic.xml :
weblogic-web-app
jsp-descriptor
param-name compilerclass
param-value compilerclassname
to compile in-process, but, for some reason, it doesn't work in 7.0
(it did in 6.1 - probably a bug or something). When JSPServlet initializes
in 7.0 it says:
... *.jsp: param compileCommand initialized to: compilerclassname>
and forks javac anyway.

Problems placing compiled jsp in the right directory

I have problems placing compiled jsp in the right directory.
          - My document root is weblogic/myserver/public_html
          - My jsp's are placed in weblogic/myserver/public_html/ram/jsp.
          - My folder for placing compiled jsp is in weblogic/myserver/compiled_jsp.
          - When weblogic compiles my jsp it places them in
          weblogic/myserver/compiled_jsp/jsp_servlet/_ram/_jsp
          Now I want to compile ram1.jsp and place it in above directory. I tried the
          following but it does not place class correct.
          1: java weblogic.jspc -d C:\weblogic\myserver\compiled_jsp ram1.jsp
          **** Places the class in weblogic/myserver/compiled_jsp/jsp_servlet
          2: java weblogic.jspc -d
          C:\weblogic\myserver\compiled_jsp\jsp_servlet\_ram\_jsp ram1.jsp
          C:\weblogic\myserver\compiled_jsp\jsp_servlet\_ram\_jsp\jsp_servlet\_ram1.cl
          ass
          What am I doing wrong ?
          cheers Per


          I would try this...
          cd public_html
          java weblogic.jspc -prefix compiled_jsp ram/jsp/ram1.jsp
          I'm not sure if -prefix is the exact option - something like that - maybe package_prefix.
          As always, things work better/easier when you leave things at the default value
          (jsp_servlet).

Problem while compiling the Device Driver source code onSolaris 8 intel pla

Hello!
We are writing Device Driver for PCI (PMC) based HS serial
communication card on Solaris 8(intel edition).The Processor
used is Celeron/Pentium III.
We are facing following problems.
1) Kindly let us know the cc compiler options for xarch=isa.
2) Presently we have included following header files.
     #include <sys/ddi.h>
     #include <sys/sunddi.h>
3)We tried to compile our driver soure file (pmc.c) using
FORTE DEVELOPER 6 UPDATE 1 with the following command.
     # cc -Xa -D_KERNEL -c pmc.c
4) The compiler is not able to reach to our source code. It prematurely fails
while compiling the system header files
5) The errors were reported during Preprocessor
compilation in /SYS/*.h header files.

"No tag library could be found with this URI" error while compiling jsp

I am using WebLogic Server 9.2 MP1, JDK 1.5.0_09, Struts 1.3.5
          I am pre-compiling jsp pages with wlappc ant task. However, I got following errors when a jsp page contains ant taglib:
          No tag library could be found with this URI. Possible causes could be that the URI is incorrect, or that there were errors during parsing of the .tld file.
          The jsp page looks like:
          <%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
          wlappc complains taglib could not be retrieved from this uri. Actually, since Struts 1.3.5, those ".tld" files are contained in strust-taglib-1.3.5.jar, folder META-INF/tld/. And I don't need to set anything in web.xml <tag-lib> tab anymore.
          All the jsp pages can be successfully compiled while being deployed to Server. So what am I missing? My build.xml file looks like:
               <target name="compile-jsp">
                    <wlappc source="${src.dir}" output="${out.dir}"
                         keepgenerated="true" optimize="true" classpathref="wl_classpath"/>
               </target>
          where "wl_classpath" contains all the struts related jar files, e.g. struts-core-1.3.5.jar, struts-taglib-1.3.5.jar, ...., and weblogic related jars, e.g. weblogic.jar.....
          I checked "beehive" samples coming with weblogic92, and found it pretty much did the same thing regarding build script and jsp files. So I am totally lost!
          Please help me out. Many thanks.
          Edited by jqian at 02/02/2007 10:24 AM

Yes sorry, you're correct. The uri I mentioned is just 1.0.
Do you have the "Oracle WebLogic Web App Extension" Facet for your web project? If not, try adding that and making sure that there is a weblogic.xml file created in the WEB-INF dir. The weblogic.xml file allows you to deploy usig a shared lib for JSTL. It should contain a library-ref element something like the following, with a version of 1.1.
<wls:library-ref>
<wls:library-name>jstl</wls:library-name>
<wls:specification-version>1.1</wls:specification-version>
<wls:exact-match>true</wls:exact-match>
</wls:library-ref>

Server Crashes while compiling JSP

          Hi,
          I have a jsp (in a web app which i have deployed on WLS 7.0)and when i invoke
          it, the server crashes and i get the below mentioned error, somewhere i read this
          is a bug in jdk. I am using the jdk shipped with WLS 7.0. Could someone urgently
          help me in this regard... I am sure that there is no problem with my jsp as sometimes
          its successfully compiled .. but most of the times i get this error/excpetion:
          An unexpected exception has been detected in native code outside the VM.

Your original post mentions issues with jsp:useBean and jsp:setProperty, now you're talking about tag libraries and directives. Can you be more specific about what you're trying to do? Are you having problems getting JDev to recognize a tag library or are you having problems with the tag library when running the app? What directive are you trying to use that causes the termination error?

Problem while creatin jsp portlet

hello all,
i get an error "500 internal server error" while creating jsp portlet. i do not write any thing in view.jsp page.
can any body tell me what is wrong with it? i am using oracle jdeveloper 10g (version 10.1.2.0.0).
thanks in advance

Hi Arshita,
This issue is corrected. You should make a search in SAP Marketplace. There is a note to correct that issue.
I cannot search from my place (mobile handy device) but you should be able to find it easily in LO-MD-BP-CM or FI-AP* or FI-AR* + TMOD* or the error number.
The note is quite recent. Probably less than 6 months.
reward points if helpful.

Problem in compiling jsp file

Hi,
i am using tomcat 4.12 and jdk 1.4.
My login page contains 3 frames. after succesful login into ur application, 7 frames are getting called.
i have called a jsp page for each frame.
sometimes while accessing my application, i am getting jasper exception like cannot resolve symbol....
for example
D:\Program Files\Apache Group\Tomcat 4.1\work\Standalone\localhost\sample\web\helpdesklogin_jsp.java:404: cannot resolve symbol
symbol : method --ite (java.lang.String)
location: class javax.servlet.jsp.JspWriter
out.write("<tr bgcolor=\"ffffff\">\r\n ");
i do not understand the what is the problem here....
likewise i am getting jasper exception. but it is not frequently occured in the frame.
is there any relation with autoflush page directive attribute...?
if it then should i increase default buffer size ?
Reply please
Thanks

Your helpdesklogin.jsp file has a compilation error. It's hard to tell, but it looks like you mis-typed out.write() somewhere.

Problem while compiling 'dll' files in Form Server..Urgent

Hi!
I'm trying to compile the library(dll) in form server and getting a message that "can not open that file".At the same time able to compile 'fmb' files which is in the same directory.
Could you please help me?
Thank you,
Denish

I am also working on Forte. Forte has an inbuilt Tomcat. You dont need to copy any files to any where in the file mount system. You need to specify the External / Internal Browser settings, So that when you try to execute it, the .jsp file can be displayed in the browser. I havent faced any problem as you said.

Can't compile JSPs with Forte 4

I upgraded to forte 4 CE. Now I cannot compile my JSP's because they are not finding my class files.
They all worked in Forte 3 ce.
If I have class MyClass()
and try to create an instance in my JSP
MyClass mc = new MyClass()
It gives the 'cannot resolve symbol' error on MyClass object.
What happened? I haven't changed anything. I have about 10 jsps and a bunch of Classes that all worked and now don't.
I checked the product support for Forte and couldn't find anything.
If anybody else had this problem and figured it out please post your solution.
Thanks.

any and all help is greatly appreciated.
thanks

Hi
I found something vague tell me if i am correct??
The problem in my .java of the JSP was that I had missed changing the name of the variable at one place and my javac gives an error something like this.
test.java:5: cannot resolve symbol
symbol : variable i
location: class test
i=4;
^
1 error
I think the jasper compiler tries to get the line numbers in the errors given by javac to map it to appropriate line numbers in .jsp file.This line number is found betn 2 colons(eg 5 above).But this missing variable causes 2 more lines to be printed with colons.Can it be the problem??
Thanks

Problem in compiling JSP page in OC4J 10.1.3.0.0

Dear all,
I started the ocj4 container that came with Jdeveloper. After starting the ocj4 server, I try to test it with the Servlet and JSP example. The Servlet Example work fine but I encounter the following error when I run the JSP example.
2006-01-12 11:08:39.379 NOTIFICATION J2EE JSP0008 Unable to dispatch JSP Page :Exception:oracle.jsp.provider.JspCompileException: <H3>Errors compiling:C:\Program Files\Oracle\j2ee\home\application-deployments\default\defaultWebApp\persist
ence\_pages\_examples\_jsp\_jsp2\_el\_basic_2d_arithmetic_2e_jsp.java</H3><pre><
/pre>
I think this should be a setup problem, please kndly advise.

After reading the theads in the forum, I am able to get the jsp running by using full path to specify the java executable.
e.g. C:\Program Files\Java\jdk1.5.0_02\bin\java -jar oc4j.jar
This should be a path problem. After I set the path variable correctly
i.e. add C:\Program Files\Java\jdk1.5.0_<version>\bin to PATH environment variable. It work fine. I hope this help the newbie like me. :D
Indeed, I wonder why we need two jdk for the oc4j. Follow the instruction, I need to install a jdk. However, I find there is another jdk under $ORACLE_HOME\jdk. This is make the situation confusing and saw quite a lot of threads are related to this problem long time ago!
