"Error running javac.exe compiler" when using ant to compile Eclipse plugin

Hi
I encounter an error "Error running C:\jdk1.5.0_06\bin\javac.exe compiler" when building my project using ant1.7.
My project has 10 eclipse plugins, and each plugin is compiled by invoking following ant target

<target name="compilePlugin">
     
     
     <delete dir="${param.plugin.dir}/${build.dir}" quiet="true"/>
     
     <delete file="${param.plugin.dir}/${param.plugin.targetJarFile}" quiet="true"/>
     <mkdir dir="${param.plugin.dir}/${build.dir}"/>
     
     <javac      srcdir="${param.plugin.dir}/${param.plugin.src.dir}"
               destdir="${param.plugin.dir}/${build.dir}"
               failonerror="${javacFailOnError}"
               verbose="${javacVerbose}"
               debug="${javacDebugInfo}"
               deprecation="${javacDeprecation}"
          optimize="${javacOptimize}"
               source="${javacSource}"
               target="${javacTarget}"
               fork="${param.fork}" memoryInitialSize="256m" memoryMaximumSize="512m">
          <classpath refid="compile.classpath" />
     </javac>
     
     <copy todir="${param.plugin.dir}/${build.dir}" failonerror="true">
          <fileset dir="${param.plugin.dir}/${param.plugin.src.dir}" excludes="**/*.java, **/package.htm*" />
     </copy>
     <jar jarfile="${param.plugin.dir}/${param.plugin.targetJarFile}" basedir="${param.plugin.dir}/${build.dir}"/>
     <delete dir="${param.plugin.dir}/${build.dir}" quiet="true"/>
</target>
Since each of first 9 plugins contains less than 500 java source files, we always set "param.fork" to false when invoking this ant target.
For the 10th plugin, it has about 1000 source files. If we set "param.fork" to false, we will get the error "Error running javac.exe compiler". So we have to set "param.fork" to true when compiling it. This week, this plugin contains about 1250 files and we get the same error again when compiling it. I tried to increase the "memoryMaximumSize" to "768", but still couldn't get through it.
BTW, There are about 150 jar files in our classpath for compiling plugins. Do many jar files cause this problem?
Any help is highly appreciated.
Many thanks
Oceanman

I encountered a very similar error and I was able to resolve it by removing the following parameters from the javac task:
fork="${param.fork}"
memoryInitialSize="256m"
memoryMaximumSize="512m"My values were not the same as yours, before I removed them, the values were set to:
fork="true"
memoryInitialSize="256m"
memoryMaximumSize="256m" Not sure why this fixed my problem but it did. I was using Ant 1.7 and Java 1.6_07 hope this helps.

SGD Portlet - Failed to build using Ant - UnsupportedClassVersionError

Hi,
I've downloaded the Sun Secure Global Desktop portlet source code from here: https://portlet-repository.dev.java.net/public/Download.html and I'm trying to compile it using Ant.
I have Ant 1.7.0 and I'm using JRE 1.4.2_15. For some reason, the Ant task fails. Using the -debug and -logfile options, it points to a VersionTask class error:

I know this portlet code was just released this week, but has anybody had any success building the portlet into a .WAR file?
Thanks in advance!
Rob.

I figured it out... the tarantella-tasks.jar file had class files in it that were compiled using jdk 6, and the rest of the project was compiled using jdk 1.4.2. Luckily, the source code was there so that I could recompile the classes back to 1.4.2 and it now works.

Error compiling single ejb using appc/ejbc (long)

This may be related to my earlier post ("no longer able to build ejb
using appc (WLS 8.1)", posted this morning), but the error and the way I
encountered it were different enough that I thought I'd post as a new
topic. I've been trying to build a project using weblogic 8.1, but I've
been running into some problems.
As a test, I tried compiling a single ejb from the command line using
the new appc compiler. I compiled the source files and moved them to a
clean build directory, along with the deployment descriptors. From the
command line, I set the system classpath to the bare minimum necessary
to build the ejb-- the jdk tools.jar, the jre rt.jar, the weblogic.jar
file, the project bin directory, the log4j.jar, and my database driver
jar (see [1] and the echoed resulting classpath at [2] below). I then
invoked appc, specifying the output and source paths ([3]). The
resulting error ([4]) shows a much larger classpath, which abruptly ends
with a "?". I ran the same test using ejbc instead of appc, and I get
the very same problem (same error message). I've never encountered
problems like these before, and other than upgrading to weblogic 8.1, my
system configuration hasn't changed. Any ideas or suggestions would be
greatly appreciated!

Hi Tim,
I just got past a similar problem by specifying the full path to javac
in build.xml. Like:
<wlappc source="${dest.dir}" compiler="C:\bea\jdk141_02\bin\javac"
/>

JSP precompilation and my .java files compilation issues / building WAR file using ANT

Hello.
I am new to working with WAR files and the whole process of it. A little
background on what we are using. We are using, WLS 6.1 SP3. I am using the
ant.bat that is supplied in the bin directory of the WLS install.
I am trying to work with ANT and getting it to build the file. I am making
progress, but at a point where I am having trouble getting my java code
files to compile using ant. I am having one issue and looking to do one
other item.
1) I would like to precompile the JSPs if possible prior to putting into the
WAR file. Not sure if this is done or not, but there was a utility when I
was working with ibm's app server that gave us the ability to do a batch
complile. Was thinking that maybe a similair concept is possibly here.
2) Having issue getting ant to compile code properly. In the compile
section of the build.xml file for ant, I tell it where the source files are,
and the destionation folder for the compiled class files. I then try to set
the classpath so that it finds the .jar files that are necessary for my
source files to complile. But, it won't find them. And not sure how come.
I may be going about this all wrong, but dont know. Here is the compile
section of the build.xml I am using:
<target name="compile" depends="prepare">
<javac srcdir="classes" destdir="${deploy.home}/WEB-INF/classes"
classpath="$(lib.home)"
debug="on" optimize="on" deprecation="off"/>
</target>
One note, I've tried many different items in the classpath line, which
don't work. if I do *.jar it fails at complie time, invalid argument. As
well as if I use *.* and so on. if I list the explicit file names, it still
doesn't seem to find them.
I was wondering if anyone could help, if you need anymore information let me
know, I can send the entire build.xml if necessary. I may be missing
items, seeing that this is my first try at using ANT.
Any help is appreciated and thanks in advance. Hopefully not sounding too
off the wall. Hopefully get some clarification and understanding.
Thank you.
Kevin.

http://e-docs.bea.com/wls/docs70/jsp/reference.html#57794
or just set the precompile flag in weblogic.xml
You can configure WebLogic Server to precompile your JSPs when a Web
Application is deployed or re-deployed or when WebLogic Server starts up
by setting the precompile parameter to true in the <jsp-descriptor>
element of the weblogic.xml deployment descriptor.

and the destionation folder for the compiled class files. I then try to set
the classpath so that it finds the .jar files that are necessary for my
source files to complile. But, it won't find them. And not sure how come.
I may be going about this all wrong, but dont know. Here is the compile
section of the build.xml I am using:
<target name="compile" depends="prepare">
<javac srcdir="classes" destdir="${deploy.home}/WEB-INF/classes"
classpath="$(lib.home)"
debug="on" optimize="on" deprecation="off"/>
</target>
maybe because you are not using curly braces there on lib.home??
if you do it the way above, you would have to list all your jars
classpath="$(lib.home)\lib1.jar:$(lib.home)\lib2.jar"
or you can nest
<javac srcdir="classes" destdir="${deploy.home}/WEB-INF/classes"
debug="on" optimize="on" deprecation="off">
     <classpath>
          <fileset dir="${lib.home}" includes="*.jar" />
     </classpath>
</javac>
One note, I've tried many different items in the classpath line, which
don't work. if I do *.jar it fails at complie time, invalid argument. As
well as if I use *.* and so on. if I list the explicit file names, it still
doesn't seem to find them.
I was wondering if anyone could help, if you need anymore information let me
know, I can send the entire build.xml if necessary. I may be missing
items, seeing that this is my first try at using ANT.
Any help is appreciated and thanks in advance. Hopefully not sounding too
off the wall. Hopefully get some clarification and understanding.
Thank you.
Kevin.

How to compile Java files using Ant in Eclipse

Hi All ,
I would like to compile all Java files using Ant in Eclipse.Since am very new to Ant and Eclipse can someone help me to create a build.xml file and let me know how to compile all the java files.
For ex , I have placed my java files inside the path C:\HEC\Terab.Initially the Terab folder holds 7 jar files which i had decompiled using JD compiler and placed the unzipped 7 folders (which contains the java files ).Now i have imported the HEC project into Eclipse using New ->Project ->Java Project.after importig it throwed me an error saying missing jar files.again i copied the jar files and placed inside Terab folder with other 7 folder.
Now How i can compile the java files and convert in to class files.Then after compiling the files i will again need to jar all the 7 folder.
Please tell me the steps i need to follow.How to write an build.xml file ? where i should keep it ? only one build.xml file is enough or should i write 7 build.xml file for each folder ? Please help me out...
Thanks & Regards

Problem compiling in Linux using ant

Hi,
I have a problem using ant in Linux.
When I build my application using ant in Windows it works fine, but when I try to build the same application with ant in Linux it gives me the following exception:
/identifier/MidiReader.java:5: error: Class or interface `javax.sound.midi.Sequence' not found in import.
I have already checked and the 'javax.sound.midi.Sequence' exists in import.
Can anybody help me?
Regards,
David

In your javac task (in Ant), you need to explicitly include any external JAR's required for compilation (see ant.apache.org's docs for info). Importing them in a Java source file does not tell Ant where to locate the JAR for linking.

Error deploying JDeveloper project using ant-sca-compile.xml

Hi all, I'm having problems on deploying a JDeveloper project using ant-sca-compile.xml. The output in C:\XXXX\YYYYY\SCA-INF\classes\scac.log is:

Same composite we were able to deploy successfully without any error, from Monday onward we are experiencing this issue.
We checked in Installation Guide provided by oracle. Oracle has suggested few memory related changes in ant-sca-compile.xml file.
Increasing Memory to avoid Compilation Errors
To avoid out-of-memory errors during compilation of a SOA composite application, you need to
increase the following memory settings.
To increase memory settings:
1. Open the ant-sca-compile.xml file in the SOA_HOME/bin directory.
2. Under the scac element, increase the following memory settings.
<jvmarg value="-Xms2048m"/>
<jvmarg value="-Xmx2048m"/>
<jvmarg value="-XX:PermSize=32m"/>
<jvmarg value="-XX:MaxPermSize=256m"/>
3. For Windows change the following memory settings to.
<jvmarg value="-Xms1536m"/>
<jvmarg value="-Xmx1536m"/>
<jvmarg value="-XX:PermSize=32m"/>
<jvmarg value="-XX:MaxPermSize=256m"/>
We did those changes but still experiencing same error. I checked H:\AIASOAProject\AIAReceiptInterface\ReceiptListEbizProvider\SCA-INF\classes\scac.log ; file its showing Could not create the Java virtual machine.

Compiling flex application using ANT throws error

Hi i m tryin to compile my flex project using ANT, and i have used [Embed(source="/assets/images/inuse/phonering.png")] lot of places in my project. How can i solve this error. I have lot of swf file also for css.
Thanks in advance
Rupam

OK, I checked my build script and remember having this problem. I'm deploying a war file that contains some java EE and flex code. So my solutions does not apply to your case, but check out this blog post.

what is the problem!
even i compile the code inside the Jcreator, after set required libraries to servlet.jar or servlet-api.jar
compile it, success then run it in IE, same error!!!.
what should i do.
stil a beginer in servlet and jsp anyway.

and Apache tomcat originally dont have servlet.jar but servlet-api.jar, i copy the servlet.jar from my friend servlet.jar is an OLD version, you should only use servlet-api.jar!
wrong name: HelloWorldPerhaps there is a mistake in the class or packagename of the source file. Post the source here.

Compiling with JRockit using ant

I am considering switching to JRockit.
Our java code is compiled using ant, with the 'javac' task.
The javac task has an option to invoke different compilers:
- classic (the standard compiler of JDK 1.1/1.2) – javac1.1 and javac1.2 can be used as aliases.
- modern (the standard compiler of JDK 1.3/1.4/1.5/1.6) – javac1.3 and javac1.4 and javac1.5 and javac1.6 can be used as aliases.
- jikes (the Jikes compiler).
etc
The Jrockit compiler is not on this list.
I have found a suggestion (http://www2.sys-con.com/ITSG/virtualcd/Java/archives/0811/pepperdine/index.html) to use an exec call as a workaround,
but are there any alternatives? I could perhaps persuade ant to use JRockit by deinstalling any other JDK's and pointing JAVA_HOME to JRockit;
what I want however is to keep the option to use different compilers.
Has anyone got any suggestions?

The javac compiler bundled with JRockit is the exact same one that you get with the Sun JDK. Oracle licenses the JDK (class libraries, tools, etc) from Sun. So I would just set JAVA_HOME to point at JRockit as you suggest.

Building weblogic ejbs with ant...

Hi, it may be not the proper place, but I haven't found a better one...
Here comes my question:
I have an ant build.xml file where I have the following tasks defined:
<property name="ejb.dtd.location" value="weblogic/ejb/deployment/xml/ejb-jar.dtd"/>
    <condition property="ejb.dtd.location" value="weblogic/ejb20/dd/xml/ejb11-jar.dtd">
      <equals arg1="${weblogic.major.version}" arg2="6"/>
    </condition>
    <property name="weblogic.ejb.dtd.location" value="weblogic/ejb/deployment/xml/weblogic-ejb-jar.dtd"/>
    <condition property="ejb.dtd.location" value="weblogic/ejb20/dd/xml/weblogic510-ejb-jar.dtd">
      <equals arg1="${weblogic.major.version}" arg2="6"/>
    </condition>

<target name="compile.ejb" depends="init">
    <javac srcdir="${srcDir.ejb}"
          destdir="${srcDir.ejb}"
            debug="${npm.debug}">
      <classpath id="ejb.cpath">
         <pathelement path="${weblogic.sp.path}"/>
         <pathelement path="${weblogic.core.path}"/>
         <pathelement location="${outDir.core}${file.separator}npm.jar"/>
         <pathelement location="${srcDir.ejb}"/>
       </classpath>
    </javac>
</target>

<target name="make.ejb" depends="prepare, compile.ejb">
    
    <ejbjar srcdir="${srcDir.ejb}">
       <weblogic destdir="${outDir.ejb}"
                 compiler="${compiler.ejb}"
                 keepgeneric="false"
                 suffix=".jar"
                 args="-g -nowarn"
                 oldCMP="false">
         <classpath refid="ejb.cpath"/>
       </weblogic>
       <include name="**/*-ejb-jar.xml"/>
       <exclude name="**/*-weblogic-ejb-jar.xml"/>
       
       <dtd publicId="-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN"
            location="${ejb.dtd.location}"/>
       <dtd publicId="-//BEA Systems, Inc.//DTD WebLogic 5.1.0 EJB//EN"
            location="${weblogic.ejb.dtd.location}"/>
    </ejbjar>
</target>This should build my ejbs with either the wls61 ejbc or the wls51 one. Anyway ant seems to have problems finding the local dtds in the classpath, although this is specified in the documentation. When I set both location attributes to point to files it works perfect. The problem is that these are in weblogic.jar for the wls61 release. This has two solutions, but either are bad in my opinion:
1. extract the needed dtds to a temp dir with a jar task and then delete em...
2. put the proper wls.jar in the classpath so ejbc could automatically resolve the dtds
Can anyone help or may be send his ant build file, where a <dtd> nested element is used for <ejbjar> for wls61?
Thank you in advance
Anton

Anton,
Your second solution is the correct one. If you look at dtd element description under ejbjar task in the Ant manual, you'll see that vendors jars are required in Ant's classpath in order for ejbjar task to resolve DTD dependencies, in which case you don't need to specify dtd elements. I don't particularly like it either. If you find a better way to solve this problem, let me know.
