Re: [fedora-java] Netbeans 5.0-beta2 , Sun Application Server 8.1 and Java-gcj

You have the option of not installing SJAS (there's even a NetBeans bundle that does not includes it). Then Download and install JBoss 4.0.3 which is supported by current Netbeans5 beta, configure Netbeans to use it (Runtime Window > Servers > Add Server) and you'll have all Java EE features. If you won't use EJB and JMS you may well forget about SJAS or JBoss and just use the included Tomcat for JSP, Servlets and WebServices. []s, Fernando Lozano

Before complaining, you should provide the info people requested to be able to help you. I asked you twice which Eclipse Plug-in you were using to run Tomcat, and you did not replied. I explained to you GCJ is not a complete Java implementation, so you should expect problems and incompatibilities. I also explained you that whatever you are using to run Tomcat under Eclipse is not part of the Eclipse packatges included Fedora Core, so it may hit something unimplemented or buggy in GCJ and so makes sense to know which plug-in or which procedure you did used to run Tomcat inside Eclipse. I also already explained to you why the root requirement and different packaging makes sense and how to circunvent it, without feedback. Looks like you want just to complain and expect a magic solution that doesn't requite you to work and to think. Many people on this list uses Eclise and Tomcat as suplied by Fedora Core 4, so they both work. Much more people use the original packages from JPackage in which the Fedora work was based. If you have a different setup or doen't have the Linux sysadmin knowledge to make this work, it's your fault, not the people who packaged Fedora Core. And if you do expect someone to help you, you have to behave in a way people can actually help you, but you don't behave like someone that want to get help. []s, Fernando Lozano

Just the person/team that provided the Tomcat "port" for Fedora. They should be flamed badly. I have pretty much given up trying to get tomcat running with Fedora's version. It seems that there are just too many problems with this version - and this was stated in several sites talking about it. I have downloaded tomcat binaries from apache's website, installed it in /usr/local directory, chown tomcat:tomcat the tomcat-5.5.12 directory and simply ran /usr/bin/dtomcat and tomcat started up with no errors as far as I can see. Finally - I can now see tomcat's index.jsp and my own index.html file in my web browser. I believe whomever created this tomcat version for Fedora has got some explaining to do. This is a horrible piece of junk, horrible waste of my time, and files moved all over the place that is it a major cause of confusion which departs from apache's standard configuration and installation. Heck, I cannot even simply define JAVA_HOME and find the binaries!!! Sheesh!! If anyone can point me to ONE definitive installation guide/faq that explains PRECISELY how to get tomcat running on FC4 from the original distro - please do! Nothing I tried so far even works! Yes, I got tomcat to "run" with a LOT OF WASTED TIME, and I was not able to get past the tomcat-user.xml file where it is trying to copy *some original file* to tomcat-user.xml.old and this causes *something* to throw an exception and on top of that fails to locate or serve any pages. It just spins it's wheels forever. I just cannot understand why Eclipse w/ Tomcat fails out of the box. This whole thing reminds me of M$ announcing a product when the product is not close to working just prevent customers from buying someone else's brand. Sheesh - what a piece of ****! Now... I have yet to get Eclipse to work in conjunction with Tomcat. We'll see how THAT goes.... Dan -- No virus found in this outgoing message. Checked by AVG Free Edition.

Tomcat is a java servlet application server and yet developers using eclipse are doing development work so why should it be a "root" requirement to run and/or start it? Sure beats me... But in any case and from what I can tell, no matter what I enter into the "Tomcat installation directory" textbox, the eclipse program keeps saying that the directory provided is not a valid tomcat installation directory and will not allow me to continue. I have used eclipse on windows for awhile and tomcat (or other server) selections runs fine - "root" or not and it even "installs" the server (along with Sun's version of their app server w/ DB support) which makes it pleasant for developers so why not follow the same pathway for linux-based developers? Why force configuration make us jump through hoops when all "we" care about is to develop applications? I *should* be able to choose *any* AS with Eclipse under Linux? Anyone care to jump in and tell me how to get tomcat started under Eclipse's control?

Netbeans 5.0-beta2 , Sun Application Server 8.1 and Java-gcj
by John W. Himpel 22 Dec '05

22 Dec '05

All, Not wanting to "pile on" on the thread from Dan Thurman, but I am unable to install the Netbeans 5.0 beta2 + AS 8.1 with java-gcj-compat installed (one single download & install from Sun). I can get the Netbeans portion of the install to run fine, but the AS 8.1 portion refuses to recognize a valid location for the JDK. Is this also a problem with AS8.1 not following the FHS? Or am I not pointing the the proper directory for the JDK? I can get Netbeans to generate and work with stand-alone Java apps just fine. I just can't get an Application Server to work to provide servlets and EJBs. Thanks. John

Eclipse and Tomcat
by Dan Thurman 20 Dec '05

20 Dec '05

Hi Folks, Has anyone gotten Eclipse and Tomcat working at all? Seems from google that this has not been working as far as I can tell. I started focusing on getting Tomcat to run and as far as I can tell, out of the box, tomcat5 fails to start. The first thing I noticed was that tomcat tries to start as a tomcat4 user -- tomcat4 on a tomcat v5.0 release? Heh! There already a tomcat user in the /etc/password file so I changed all places where tomcat4 user was located. In /etc/initd.d/tomcat and in /etc/tomcat5/tomcat5.conf Then I tried to start it again - nope it fails. It breaks because apparently for java v1.50 which I have installed, tomcat does not even know where to find jta.jar file. Sheesh - it looks like this file was not included because of licensing issues? Since I had java v1.4 installed, and the jta.jar was found at /usr/lib/jvm/java-1.4.2-gcj-..., I simply copied it to /var/lib/tomcat5/common/lib directory and deleted the [jta].jar broken link. Then I ran /etc/init.d/tomcat5 and now it appears to run with no errors (as far as I can tell). Now - what port is tomcat running on so that I can see if it is running! Well, it is not port 80 nor port 8080 (I am running apache at 80, and there is nothing at 8080) I cannot seem to find a tomcat listener in netstat -a so I cannot tell if tomcat is running successfully or not!?!? Can anyone give me any pointers as to how to locate what port tomcat might be running at? Thanks! Dan -- No virus found in this outgoing message. Checked by AVG Free Edition.

The specific dialog box appears when you attempt to run the web-application project (RunAs->Run on Server) and you are then to choose the application server (tomcat 4,5,5.5) and provide the tomcat installation directory otherwise you cannot run the application. I entered the pathname of /usr/share/tomcat5 and it does not allow me to continue. I tried different tomcat versions (5.0, 5.5) and neither worked. So- I am stuck - and cannot even get my application to run at this time. Any ideas? Dan -- No virus found in this outgoing message. Checked by AVG Free Edition.
