RE: Is this the way to do it?
HI Magnus,
Make use of the simple datatype 'boolean' instead of the object 'Boolean'
boolean BoolDans = false;
boolean BoolAllman = false;
boolean BoolFof = false;
boolean BoolTextil = false;
boolean BoolHp = false;
if (request.getParameter("IntresseDans") != null) {
BoolDans = true;
}
etc
There is simple datatypes for Interger (int), Long (long),...etc.
Check the Java basics book for more info.

Tomcat 4.0 - Setting Working dir ?
Hi, I need to set '%CATALINA_HOME%\work' to 'C:\Temp\work'. How can I do this? Best regards Joacim Järkeborn
RE: Tomcat 4.0 - Setting Working dir ?
> I need to set '%CATALINA_HOME%\work' to 'C:\Temp\work'. I found the setting in '%CATALINA_HOME%\conf\web.xml' jsp org.apache.jasper.servlet.JspServlet logVerbosityLevel WARNING scratchdir C:\Temp\Impact\work 3 It's placing all generated code there BUT when starting Tomcat it creates a '%CATALINA_HOME%\work' directory containing some empty directories. I can't have this since Tomcat will be on a CD later on. Any suggestions? BR Joacim
RE: Tomcat4 and Apache
> I'm installing Tomcat4 Release !! Need I to install Apache ? Nope, you can change Tomcat to listen at port 80. Apache is better to handle static data and do you need very good performance you should use Apache + tomcat. > How I connect Tomcat4 with Apache ? Yes, using mod_webapp connector. For now you need to build it but I recommend that you wait until the binary is available. From: http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.0/ "Binary and source distributions of the mod_webapp connector will be posted on Wednesday, September 19, 2001, for a variety of platforms. If you wish to build the connector in the mean time, please download the jakarta-tomcat-connectors CVS repository, and follow the build instructions in the README.txt file of the webapp subdirectory." // Jocke

RE: How do I fix the Tomcat 4.0 (Catalina) - Bootstrap Error
Do you have a Win9x system? -- 2) An "out of environment space" error when running the batch files in Win9X/ME-based operating systems. Right-click on the STARTUP.BAT and SHUTDOWN.BAT files. Click on "Properties" then on the "Memory" tab. For the "Initial environment" field, enter in something like 4096. After you click apply, Windows will create shortcuts in the directory with which you can use to start and stop the container. -- Best regards Joacim Järkeborn Consultant - Systems Development > -Original Message- > From: Chris [mailto:[EMAIL PROTECTED]] > Sent: den 21 september 2001 17:34 > To: [EMAIL PROTECTED] > Subject: How do I fix the Tomcat 4.0 (Catalina) - Bootstrap Error > > > Hi > > I have installed the Tomcat 4.0 on my machine but when I run > it I get the > following error : > Exception in thread "main" java.lang.NoClassDefFoundError: > org/apache/catalina/startup/Bootstrap > > How can I fix this or what must I set to get past this error. > I have set > JAVA_HOME and CATALINA_HOME.

RE: JSP vs. ASP
Some differences: A ASP page is compiled into memory (every time it's accessed I think) A JSP page is pre-processed into a Java class (*.java, Servlet) and then compiled (*.class). This happens ONE time only. If the JSP-page has changed it's being processed again. Everything is on disk. Then it's executed as Servlet. It takes a little more time at first but then are faster than ASP.

Poolman 2.0.4 and Tomcat 3.2.3
Hi, Since I need to get a DataSource from some JNDI I have downloaded PoolMan 2.0.4. When I am trying to run "JSP Database Client" Tomcat terminates. In /lib I have the following jars: poolman.jar, jdbc2_0-stdext.jar, jta.jar, xerces.jar, mm.mysql-2.0.4-bin.jar I also have the poolman.xml in the same dir, but this is added to CLASSPATH in /bin/tomcat.bat: if exist "%TOMCAT_HOME%\lib\poolman.xml" set CP=%CP%;%TOMCAT_HOME%\lib\poolman.xml What's wrong?

Yes, of course.
