Can't compile Servlet program(error in setting classpath in XP)
I encountered a similar problem as 'hereispaddy'.
"I have recently written a servlet program. When I compile the program (let's say "HelloWorld.java"), I've got the following error message:
package javax.servlet does not exist
I've download the class files and set the classpath already. Have I missed anything? "
i would like to ask, how to set the following in Windows XP:
set CATALINE_HOME=C:\PROGRA~1\APACHE~1.0
set CLASSPATH=.;%CATALINE_HOME%\COMMON\LIB\SERVLET.JAR;C:\JDK1.4\BIN;
*ive tried in control panel->system->advanced->environment variables->
variable name:CATALINE_HOME
variable value:C:\Program Files\Apache Tomcat4.0 (and)
variable name:CLASSPATH
variable value:.;%CATALINE_HOME%\common\lib\servlet.jar;C:\jdk1.4\bin
but failed!
Could anyone kindly tell me what's wrong with my setting?
Thx a lot!!!
Does Tomcat work? Can run the examples on the home page?
The only suggestion I have at this point is to get rid of the spaces in
C:\Program Files\Apache Tomcat4.0
But I am still in Win98 , so I am just guessing.

I have jsdk2, but I can't compile servlet program
I have jsdk2 version. which create in my c:\ dirve a folder jdk1.3. I do all the program from that. But I found that some of the class files of Servlet (servletRespose etc ) is missing. What I do to recover that. Even I can't compile any servlet program from that. Pls reply to my problems.
Regards.
RanjanThe Servlet API is part of J2EE (Java 2 Enterprise Edition). It is not included in the Standard Edition.
So you need to download and install the J2EE reference implementation or another servlet engine such as Apache Tomcat ( http://jakarta.apache.org/tomcat ). Don't forget to put the Tomcat JAR files in your CLASSPATH when compiling your servlet program.

thanksHi,
I'm trying to figure out how to use this decompiler, I have downloaded it to windows 2000 platform and it unzips to 1 file with extension "1-bin" - OS doesn.'t know what to do with and neither do I ;) - I'm starting out on something here and this tool would be useful.
Thanks for any install instructions you might have.

Hi,
I've had a similiar problem with decompiling certain
classes. Try the following decompiler,
http://jrevpro.sourceforge.net, after using this one,
the code decompiled fine, this tool is also a
disassembler and quite a nifty one i might add. :)
Hope this helps!

Did you put the servlet.jar in your classpath? -
I can't compile servlets, either
I am following the instruction of Java tutorial in
"http://developer.java.sun.com/developer/onlineTraining/J2EE/Intro2/servlet/servlet.html". I copied the code for BonusCalculationServlet on my computer and tried to compile it but i couldn't. The error message it could not recognized all the javax package classes (javax.servlet...). I installed j2 ee sdk 1.3.1 and j2se 1.4.0. I set all the environmental variable correctly and i did set classpath correctly ( classpath = %J2EE_HOME%/lib/j2ee.jar).
If i use jsdk2.1(jdk1.2.1 servlet extension) then I can compile it. Can anybody help with this. ThanksYou need to install a servlet runner such as Tomcat and check out Apache Jakarta-Ant for performing your builds.
http://jakarta.apache.org/tomcat/
http://jakarta.apache.org/ant/
Tomcat has a great little Application Developer Guide. Check that out here:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/appdev/index.html
And check out a pre-assembled Ant build sample here:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/appdev/sample/
Once you have Tomcat-4.1.10 set up, make appropriate changes to paths in the sample build file to match your system, drop your servlet classes into the "src" directory creating whatever package directory structure you need inside that and then just go to the command line and type:
ant compile
Your classes will now have been compiled and you will have your WAR structure all set to deploy to Tomcat.

Please ignore my previous Thread.
Where do you get the nessecary libaries to compile servlets, and what directory of the JSDK1.4.0/ directory do you put them in (Im using Win98se)File To Compile:

How can I fix a program error so I am able to save files?
My version of Photoshop CS6 is suddenly not allowing me to save any files at all. I can't save .psd, .jpg, .gif, etc. When I try to save it it pops up with a program error message. I haven't had this program very long so I would like to get it fixed so I can start using it. Thanks!
Hello! I'm guessing that you either have allowed Photoshop to use an inadequate amount of disk space, which you can change by going to Edit>Preferences or you have run out of space on the disk you have told Photoshop to use. Either free up space, or, if you have a second hard drive, go to Edit>Preferences and it should be under General. I haven't gone through all of these preferences menus yet, so can't promise you'll find everything there, but you should at least get some leads. I know there are more specific options under preferences, but as I said, I haven't gone through those yet, and don't know where to find disk space options.
Hope this helps!

oscarhua1:install Java SE,set the path variable to the directory of the bin folder(including bin).
2:download the JavaMail 1.4 release from http://java.sun.com/products/javamail/downloads/index.html
3:extract the downloaded file to any location and add the directory of its mail.jar file to classpath.
4:download the JavaBeans Activation Framework 1.1release from
http://java.sun.com/products/javabeans/jaf/downloads/index.html#download
5:extract the downloaded file to any location and add the directory of its activation.jar file to classpath.
then everything goes smoothly

How can I compile servlets? I'm still having problems...
Ok, I've installed J2SE and it's been working perfectly using command-line compiling (javac) and also with the Eclipse IDE.
Now I want to start using Servlets and JSP so I installed the JWSDP (Java Web Services Developer Pack). I couldn't quite figure it out, so I installed J2EE on top of everything.
Eclipse doesn't recognize "import javax.servlet.*;" and neither does the command-line compiler javac.
Am I doing something wrong?I don't know anything about ServletExec or how it expects you to deploy a Web app. You're on your own there. I don't know if ServletExec supports WAR files or even follows the specifications for directory structures.
Look, there are two separate issues here: compiling and running.
Whatever you do, however you do it, you've got to have a JAR in your CLASSPATH that has the javax.servlet and javax.servlet.http packages in it when you compile. You don't need the whole J2EE app server, just the JAR with those packages.
When you deploy and run the app, you'll do it on the server. It'll have the appropriate JARs.
To me, app server and J2EE are synonymous. Yes, the j2ee.jar comes with Sun ONE if that's what you've downloaded.
You can use Tomcat, which is a free servlet/JSP engine. I believe that Sun ONE has Tomcat bundled inside. If so, it'll have the servlet.jar in there somewhere. Tomcat stores it in TOMCAT_HOME/common/lib.

Can't compile Servlets in J2EE 1.4 SDK 5.0
Hi,
I downloaded J2EE 1.4 SDK 2005Q2 UR2 which has J2SE 5.0 and has built in support for Java Servlet implementation. But when I try to complie a Servlet, compiler cribs javax.serlet.* package can't be found.
Some solutions suggested on this forum direct one to include j2ee.jar or servlet.jar in the classpath. I have added j2ee.jar in the classpath but still the same thing happens. And there's no servlet.jar in this instalation.
Any pointers???Hi,
I downloaded J2EE 1.4 SDK 2005Q2 UR2 which has J2SE
5.0 and has built in support for Java Servlet
implementation. But when I try to complie a Servlet,
compiler cribs javax.serlet.* package can't be
found.You realize, of course, that you misspelled "servlet" - you left out the 'v'. Check your code.
Some solutions suggested on this forum direct one to
include j2ee.jar or servlet.jar in the classpath. I
have added j2ee.jar in the classpath but still the
same thing happens. And there's no servlet.jar in
this instalation.Right. servlet.jar is for Tomcat 4.x and earlier; it's servlet-api.jar for Tomcat 5.x and later. J2EE reference app server uses j2ee.jar.
Did you ever think to open the JAR and make sure that the package was inside? Might be worth doing instead of taking it on faith. If you can't find it, the class loader won't, either.
Any pointers???See above. If that's not it, you think you have the JAR in your CLASSPATH but you don't. Don't argue with the compiler. Figure out what YOU did wrong.

Learnit's not CLASS_PATH, it's CLASSPATH.
Directory paths with spaces in them are problematic. Surround them with double quotes.
I think the best thing is not a CLASSPATH environment variable. Better to use the -classpath option on javac.exe when you compile.
So your command to compile might look something like:
javac -classpath .;"C:\Program Files\Tomcat\jakarta-tomcat-5.0.28\common\lib\servlet-api.jar" *.java%
